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图；
图2是根据本发明一个实施例的冰箱的分解图，其中隐去了外壳；
图3是根据本发明一个实施例的冰箱的截面图，其中隐去了外壳；
图4是图3的A处放大图；
图5是根据本发明一个实施例的冰箱中接水盘与加热丝安装关系的示意图；
图6是根据本发明一个实施例的冰箱中接水盘的示意图；
图7是根据本发明一个实施例的冰箱中加热丝的示意图。
具体实施方式
在本实施例的描述中，需要理解的是，术语“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“进深”等指示的方位或置关系为基于冰箱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。
请参见图1，本实施例的冰箱1一般性地可包括箱体10，箱体10可以包括外壳、内胆、隔热层及其他附件等。外壳是冰箱1的外层结构，保护着整个冰箱1。为了隔绝与外界的热传导，在箱体10的外壳和内胆之间加有隔热层，隔热层一般通过发泡工艺构成。内胆可以为一个或多个，根据功能可以任意被划分为冷藏内胆、变温内胆、冷冻内胆等，具体的内胆个数以及功能可以根据冰箱1的使用需求进行配置。在本实施例中内胆至少包括底部内胆100，底部内胆100一般可为冷冻内胆。
请参见图2和图3，本实施例的冰箱1的底部内胆100的底部设置有冷却室140，冷却室140内设置有蒸发器220，蒸发器220为冰箱1提供冷量。具体地，底部内胆100的下方设置有分隔盖板210，分隔盖板210横向设置于底部内胆100内，用于将底部内胆100分隔出冷却室140和位于冷却室140上方的冷冻室160。
也即是，本实施例中的蒸发器220位于底部内胆100的下方，这种设置方式能够避免传统冰箱中蒸发器占用冷冻室后部空间而导致冷冻室的进深减小，尤其对于对开门的冰箱来说，在冷冻室横向尺寸本就较小的情况下，增加其深度尺寸尤为重要，由此提升了冰箱1的空间利用率，方便了体积较大且不易分隔物品的存放。
另外，传统冰箱中，位于最下方的冷冻室所处位置较低，用户需要大幅度弯腰或蹲下才能对该冷冻室进行取放物品的操作，不便于用户使用，尤其 不方便老人使用。而本实施例中，由于冷却室140占用了底部内胆100的下方空间，抬高了冷却室140上方的冷冻室160的高度，降低用户对冷冻室160进行取放物品操作时的弯腰程度，从而可提升用户的使用体验。
请参见图3，在本实施例中，蒸发器220布置于冷却室140的前部，并倾斜设置在冷却室140中。这种方式突破了现有技术减少进深尺寸需要使蒸发器水平放置的技术桎梏。虽然扁平长方体的蒸发器220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140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220倾斜设置的布局方式是本实施例做出的主要技术改进之一。在一些具体的实施例中，蒸发器220的倾斜角度范围设置为7～8°，例如可以设置为7°、7.5°、8°，优选为7.5°。
请参见图2和图3，在本实施例中，冰箱1还可以包括送风组件，送风组件设置于蒸发器220的后方。送风组件可以包括离心风机和送风风道150。其中离心风机倾斜地设置于蒸发器220的后方，其吸风口朝向前下方，出风口朝向后方，并配置成促使形成经由蒸发器220送向冷冻室160的制冷气流，送风风道150与离心风机的出风口连通，并向上延伸，配置成将离心风机排出的气流输送至冷冻室160。离心风机的前端至蒸发器220的水平距离占箱体10沿前后方向的进深尺寸的比例小于4.5％，例如设置为4.3％。
请参见图2和图3，冰箱1还可以包括风道背板240，风道背板240设置于底部内胆100的后壁的前方，其可以大致平行于底部内胆100的后壁，以与底部内胆100的后壁共同限定出送风风道150，送风风道150与制冷风机的出风口连通，并向上延伸。并且风道背板240开设有至少一个送风口242，送风口242用于连通送风风道150以及冷冻室160。由于送风风道150与冷却室140相连通，且分隔盖板210作为冷却室140的分隔部，因此，风道背板240可以与分隔盖板210相抵接，以起到密封冷却室140和送风风道150之间间隙的作用。在一些优选的实施例中，制冷风机还可以为离心式风机。
请参见图2和图3，制冷风机还可以包括风机叶片250、风机上盖252和风机底壳254。风机上盖252从风道背板240的下端倾斜向下伸入冷却室140内，风机底壳254罩扣在风机上盖252上，风机叶片250设置在风机上盖252和风机底壳254形成的风机腔内(图中未标号)。风道背板240与风 机上盖252还可以配置成一体成型件，以简化安装流程，降低成本，又可以使得整个风道结构更加稳固。
请参见图2和图3，冰箱1还可以包括回风罩230，回风罩230设置于冷却室140的前部，其上开设有连通冷却室140和冷冻室160的至少一个前回风口232。
冷却室140内的蒸发器220与周围的空气进行换热，使其温度降低以形成制冷气流，在制冷风机促使下，制冷气流从冷却室140排向送风风道150，然后从风道背板240上的送风口242进入冷冻室160，以与冷冻室160的空气进行换热，降低冷冻室160的温度。制冷气流换热后可以通过回风罩230上的前回风口232回流至冷却室140，继续与蒸发器220进行换热，从而形成循环的气流路径。
请参见图2至图5，本实施例中的底部内胆100的底壁上开设有接水槽1241，接水槽1241的底部开设有排水口1241a；冰箱1还包括接水盘300和加热丝400，接水盘300设置于蒸发器220与底部内胆100的底壁之间，配置成承接蒸发器220上的水，并且接水盘300与接水槽1241相对的区域设置有多个通孔322，加热丝400盘绕设置于接水盘300与蒸发器220之间，配置成为蒸发器220化霜提供热量，并且加热丝400具有穿过通孔322向接水槽1241延伸的延伸部412。
冰箱1在使用过程中由于蒸发器220的温度相对外部温度较低，可能出现蒸发器220将外部空气中的水蒸气凝结后结霜附着在蒸发器220的表面，这样容易影响冰箱的制冷效果及效率，甚至会出现质量故障。
加热丝400盘绕设置于接水盘300与蒸发器220之间，其可以按照一定的参数对蒸发器220进行间隔性地加热，以融化蒸发器220上的结霜。比如当冰箱1的压缩机开始工作时，蒸发器220的温度降低，此时产生的凝结水或者化霜水的量较大，加热丝400启动，开始进行除霜工作。当然，加热丝400的启停还可以为受控于其他控制逻辑，为了不模糊本发明的发明点，在此不作过多阐述。
接水盘300设置于蒸发器220与底部内胆100的底壁之间，当蒸发器220上的结霜被加热丝400融化后，接水盘300能够承接并收集这些化霜水，并将化霜水导流至底部内胆100的底壁上的接水槽1241中。接水槽1241的底部开设有排水口1241a，该排水口1241a一般性地可以连通接水槽1241和位 于底部内胆100后侧下方的压机舱，以使得这些化霜水在压机舱中被蒸发，进而防止化霜水滴落在冰箱1的其他元器件上造成故障。
排水口1241a位于接水槽1241的底部，加热丝400设置于接水盘300与蒸发器220之间。也就是说，排水口1241a与加热丝400具有一定的距离，而且两者之间还间隔有接水盘300，这可能会导致一些较大体积的冰块掉落在排水口1241a时，加热丝400无法及时地融化该冰块，导致排水口1241a被堵塞，排水不利。
因此，为了克服上述缺陷，在本实施例的冰箱中，接水盘300与接水槽1241相对的区域设置有多个通孔322，加热丝400具有穿过通孔322向接水槽1241延伸的延伸部412。该延伸部412至少一部分设置在接水槽1241中，其可以缩短加热丝400与排水口1241a之间的间距，使得加热丝400的热量能够及时地传递至排水口1241a处，防止排水口1241a被堵塞。另外，由于加热丝400设置于接水盘300与蒸发器220之间，当延伸部412穿过通孔322向接水槽1241延伸，还能够限定接水盘300与加热丝400之间的位置。
另外，通过延伸部防止排水口堵塞的同时，也可以避免在排水口额外增加加热丝，进而降低了冰箱的成本。
在本发明一些具体的实施例中，延伸部412可以由加热丝400的中部向接水盘300的方向弯曲形成，加热丝400的直径可以略小于通孔322的尺寸，以允许延伸部412能够穿设于通孔322，例如，加热丝400的直径可以为4.5mm，通孔322的宽度可以为6mm等，在此不一一列举。
加热丝400还可以被配置为铝管加热丝，接水盘300还可以被配置为铝制接水盘，铝制接水盘300主要作用是可以把加热丝400的热量有效、快速地传递到蒸发器220的各个部位，以增大蒸发器220的受热面积，提高化霜效率。
在本发明一些具体的实施例中，延伸部412的底端与排水口1241a的距离还可以配置成3mm～5mm范围内任意数值，例如，3mm、4mm或者5mm等，以满足在不影响排水口1241a排水效果的前提下，最大限度地靠近排水口1241a，防止排水口1241a被堵塞。
请参见图3和图4，在本发明一些实施例中，底部内胆100的底壁可以包括第一倾斜部122、下凹部124、第二倾斜部126和第三倾斜部128，第一倾斜部122从底部内胆100的底壁的前端从前至后向下倾斜设置，下凹部124 设置于第一倾斜部122的后侧，并配置成从横向中部向两侧向上倾斜，从而在横向中部形成接水槽1241，第二倾斜部126从接水槽1241的后端从前至后向上倾斜设置，第三倾斜部128从第二倾斜部126的后端从前至后向上倾斜设置。
在本实施例中，第二倾斜部126相对于底部内胆100的底壁的前端倾斜设置，蒸发器220可以直接或间接地设置在第二倾斜部126上，而且接水槽1241形成于位于第二倾斜部126下侧的下凹部124处，这可以使得当蒸发器220倾斜地设置于第二倾斜部126时，其上的化霜水能够向下顺畅地排入接水槽1241内。
在一些具体的实施例中，第三倾斜部128的倾斜角度大于第二倾斜部126的倾斜角度，且第三倾斜部128相对于水平方向的倾斜角度还可以设置为36～37°，例如可以设置为36°、36.5°、37°，优选为36.7°。
请参见图4至图6，在本发明一些实施例中，接水盘300包括前部板段310、中部板段320和后部板段330，前部板段310位于接水盘300的前端，并与第一倾斜部122之间形成间隔；中部板段320从前部板段310的后端倾斜向上延伸，其前部位于接水槽1241的上方并开设有多个通孔322，并且其后部贴靠于第二倾斜部126；后部板段330从中部板段320的后端倾斜向上延伸，并贴靠于第三倾斜部128。
蒸发器220整体呈扁平长方体状，设置于中部板段320上，其前端底部抵靠于中部板段320与前部板段310的交界处，从而使蒸发器220以第二倾斜部126的倾斜角度设置，以取得上述实施例中蒸发器220倾斜设置的技术效果。
在本实施例中，前部板段310可以抵靠于第一倾斜部122处，中部板段320从前部板段310的后端倾斜向上延伸，后部板段330从中部板段320的后端倾斜向上延伸，当蒸发器220设置在位于中部板段320上时，前部板段310、中部板段320和后部板段330可以完全包裹蒸发器220，以最大限度地收集蒸发器220上的化霜水。
进一步地，在本实施例中，由于蒸发器220设置在中部板段320上，中部板段320从前部板段310的后端倾斜向上延伸，其前部位于接水槽1241的上方。也就是说，蒸发器220的前部也朝向接水槽1241倾斜，这也可以缩短蒸发器220的前部与接水槽1241之间的距离，进而缩短了加热丝400 整体与接水槽1241之间的距离。而本发明正是由延伸部412和蒸发器220倾斜设置这两种方式共用配合来实现缩短加热丝400与接水槽1241之间的距离，以对排水口1241a处进行加热。
请参见图4，第一倾斜部122还可以形成有凸起部180，前部板段310可以搭靠在凸起部上，以使得前部板段310与第一倾斜部122之间形成间隔，该间隔能够连通接水槽1241与冷却室140，保持接水槽1241与冷却室140的压力相等，利于排水。
在一些具体的实施例中，前部板段310与第一倾斜部122的间隔距离还可以配置成20mm～45mm范围内任意数值，例如20mm、30mm或者45mm等。
请参见图2和图7，在本发明一些实施例中，加热丝400包括多个平行区段410和多个连接区段420，多个平行区段410沿相对于冰箱1的横向平行间隔设置，延伸部412形成于平行区段410上；每个连接区段420弯曲延伸设置于两个相邻的平行区段410的同侧端部之间，以使得多个平行区段410依次串接。
也即是，本实施例中的加热丝400呈S型盘绕设置，平行区段410的数量以及相邻两个平行区段410的间隔距离可以根据蒸发器220的面积进行配置，以使得蒸发器220能够受热均匀。延伸部412可以由平行区段410向下弯曲后形成，以凸出加热丝400的表面并向下延伸，对排水口1241a处进行加热。
请参见图6和图7，加热丝400还可以包括扩展区段430，其中部贴靠于前部板段310设置，并向两侧延伸至靠近底部内胆100侧壁的位置，以对蒸发器220前方区域进行化霜加热。对于蒸发器220顶部在化霜过程掉落的冰块以及侧部回风口处出现的冰块进行化除，使得加热丝的作用区域更加全面，进一步保障了化霜排水顺利进行。
对应地，接水盘300的侧部还可以向两侧延伸形成扩展板段340，用于承载扩展区段430。
请参见图6，在本发明一些实施例中，中部板段320的上表面的后部与多个连接区段420相对的位置上设置有多个限位部350，以对连接区段420进行限位。
在本实施例中，限位部350可以为从中部板段320的上表面拱起的多个 卡槽，位于同侧的连接区段420可以伸入卡槽内，以将加热丝400与中部板段320进行限位，以简化组装流程。在一些优选的实施例中，限位部350呈半圆球状，其尽量降低对制冷气流的影响。
请参见图6，中部板段320的上表面的前部还开设有多个排水孔360，以将接水盘300上承接的水通过排水孔360以及通孔322与延伸部412之间的间隙排入接水槽1241。
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。
