Description

冷藏送风总成以及对开门冰箱
本申请要求了申请日为2018年2月9日，申请号为201810136706.9，发明名称为“冷藏送风总成以及对开门冰箱”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及制冷设备技术领域，涉及一种冰箱，尤其是一种带有预先组装的冷藏送风总成的对开门冰箱。
背景技术
现有技术的单系统对开门冰箱冷藏室送风风门一般都是安装在冷藏室内部，为了保证风门密封及冷藏室送风效果，在冷藏室上部设置有冷藏送风风道，风道内设置有风门，控制由蒸发器进入冷藏室的送风量，从而实现冷藏室温度的控制。
图1所示为现有技术的一种对开门冰箱风道的剖视图。如图所示，这种对开门冰箱的冷冻室a与冷藏室b左右并排设置，其进一步包括：冷冻内胆1、风机盖板2、冷冻风机3、风机支架4、蒸发器5、中梁泡沫6、冷藏风门7、冷藏风道泡沫8、冷藏风道盖板9、发泡箱体10。其中，所述冷藏风门7设置于冷藏室b内。
图2所示为图1现有技术的对开门冰箱的剖视图。如图所示，在冰箱工作过程中，蒸发器5制冷，冷冻风机3工作，冷冻风机3将制冷后的空气通过风机盖板2和中梁泡沫6分别送入冷冻室a和冷藏室b。在冷藏室b的送风入口设置有冷藏送风风道，冷藏送风风道由冷藏风门7、冷藏风道泡沫8、和冷藏风道盖板9组成。当冷藏室需要制冷时，冷藏风门7打开，冷空气通过冷藏风道泡沫8和冷藏风道盖板9进入冷藏室，对冷藏室进行制冷；当冷藏室不需要制冷时，冷藏风门7关闭，冷空气无法进入冷藏室内部。
在现有技术的这种冰箱风道由于从蒸发器进入冷藏室的空气温度比较低(低于10摄氏度)，为了避免冷藏室风道出现凝露现象，冷藏送风风道会内部会采用聚苯乙烯泡沫进行隔热，导致冷藏送风风道的尺寸比较大，使冰箱冷藏室内部有效容积减少10L以上，不能满足用户对于冰箱冷藏室容量的要求。
图3所示为图1现有技术的制冷过程中空气循环示意图。如图所示，在冷藏制冷过程中，通 过蒸发器的冷空气经过冷冻风机，一部分风直接吹入冷冻室内部a，另一部分风通过冷藏风门，然后经过中梁泡沫，再经过冷藏风道送入冷藏室b内部。进入冷冻室a和冷藏室b的空气对食物进行制冷后，通过冷藏回风和冷冻回风到达蒸发器底部，依次循环。
在现有技术中，在冷藏室b不需要制冷，冷藏风门关闭情况下，一旦出现冷藏风道泡沫对接不好或者密封垫变形情况下，冷气会通过B风道漏风进入冷藏室b中，导致冷藏室温度过低，造成冷藏室b内食物冻坏。
综上所述，如何尽可能扩大冷藏室有效容量，并有效避免冷气泄漏成为了冰箱结构设计领域技术人员亟待解决的问题。
发明内容
为解决上述问题，本发明提供一种冷藏送风总成以及对开门冰箱，能够扩大冷藏室有效容量，并有效避免冷却泄漏。
为实现上述目的，本发明一实施方式提供一种冷藏送风总成，其应用于对开门冰箱，该对开门冰箱包括左右并排的冷冻室以及冷藏室、冷冻风机、风机支架、蒸发器、发泡箱体、冷冻冷藏中梁，所述冷藏送风总成进一步包括：冷藏送风风门，所述冷藏送风风门设置于所述冷冻室内靠近于所述冷冻风机的位置；冷藏送风风道，其两端分别连通所述冷冻室以及所述冷藏室，包括先沿水平方向延伸到冷冻冷藏中梁上段的第一段，以及沿着冷冻冷藏中梁向下段延伸的第二段；风门隔热件，包覆于所述冷藏送风风门外侧；中梁风道隔热件，包覆于所述冷藏送风风道第一段。
作为本发明一实施方式的进一步改进，所述对开门冰箱还包括支架卡爪，通过所述风门隔热件以及所述支架卡爪将所述冷藏送风风门固定在所述风机支架上。
作为本发明一实施方式的进一步改进，所述风机支架、冷冻风机、冷藏送风风门、风门隔热件、中梁风道隔热件预先组装成所述冷藏送风总成。
作为本发明一实施方式的进一步改进，所述风门隔热件以及中梁风道隔热件为聚苯乙烯泡沫。
作为本发明一实施方式的进一步改进，所述风门隔热件以及中梁风道隔热件的厚度介于15mm至25mm的范围内。
作为本发明一实施方式的进一步改进，所述风门隔热件以及中梁风道隔热件的厚度为20mm。
作为本发明一实施方式的进一步改进，所述风门隔热件以及中梁风道隔热件为其他类型的塑料。
作为本发明一实施方式的进一步改进，所述塑料隔热件或者新型复合材料隔热件上设置有加 热丝或者真空隔热板。
作为本发明一实施方式的进一步改进，所述冷藏送风风道的第二段与所述冷冻冷藏中梁的长度比例介于0.2到0.9之间。
本发明一实施方式还提供一种对开门冰箱，其包括左右并排的冷冻室以及冷藏室、冷冻风机、风机支架、蒸发器、发泡箱体，以及如上所述的冷藏送风总成。
与现有技术相比，本发明能够扩大冷藏室有效容量，并有效避免冷却泄漏。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
需要理解的是，除非另有明确的规定和限定，在本发明的描述中，术语“中心”、“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于用户面对冰箱的门体一侧为视角所确定的，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。此外，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。
请参阅图4为本发明一实施方式的对开门冰箱风道的剖视图。如图所示，这种对开门冰箱的冷冻室a’与冷藏室b’左右并排设置，其进一步包括：冷冻内胆1’、风机支架2’、冷冻风机3’、蒸发器4’、冷藏送风风门5’、风门隔热件6’、冷藏内胆7’、中梁送风隔热件8’、冷藏风道9’、发泡箱体10’。
为了避免冷藏风道占用冷藏室有效容积，本发明取消了现有技术中设置在冷藏室中的冷藏风门，取而代之的是，在冷冻室中设置冷藏送风风门，该冷藏送风风门集成于蒸发器上部，这样可 以有效的提高冷藏室的容积率，同时为了方便冷藏送风风门密封，在冷藏送风风门外侧还包覆有风门隔热件，通过风门隔热件和支架卡爪把冷藏送风风门固定在风机支架上。在冰箱组装时，首先，把风机支架2’、冷冻风机3’、冷藏送风风门5’、风门隔热件6’提前集成组装在一起，形成冷藏送风总成；然后，直接把冷藏送风总成安装到冷冻室内。
进一步地，由于冷藏送风风门设置在冷冻室内，因此为了防止冷藏送风风门结冰，一般在冷藏送风风门上增设盖板，并在盖板上安装加热丝。
进一步地，为了防止冷冻室内的冷藏送风通道内部结冰，风门隔热件需要延伸包覆至少部分所述冷藏送风风道，且有一定的隔热厚度。在一个实施方式中，风门隔热件为聚苯乙烯泡沫，且厚度介于15mm至25mm的范围内。最佳地，聚苯乙烯泡沫厚度为20mm左右。
进一步地，如果采用聚苯乙烯泡沫之外的其他材料，例如，其他类型的塑料。如采用其他材料，相应地，隔热件的厚度会发生变化。
进一步地，为了防止冷藏风门结冰，一般在塑料隔热件上设置有加热丝或者真空隔热板。
进一步地，冷藏风道可以只沿水平方向延伸到中梁上段，并由较少的出风口引出到冷藏室。更佳地，冷藏风道包括先沿水平方向延伸到中梁上段的第一段，然后沿着中梁向下延伸的第二段，并由更多的出风口引出到冷藏室，籍此提高冰箱冷藏室的制冷效率。
图6为本发明一实施方式的制冷过程中空气循环示意图，本发明将冷藏送风风门设置在冷冻室a’内部，还能够有效解决现有技术中存在的冷藏风道漏风问题。如图所示，当冷藏室b’需要制冷时，冷冻风机工作，冷藏风门打开，此时冷空气通过冷藏送风风门5’→风门隔热件6’→中梁风道隔热件8’→冷藏风道9’进入冷藏室；当冷藏室b’不需要制冷时，冷藏风门关闭，可以完全切断冷冻室a’与冷藏送风风门5’，避免冷藏室b’漏风。
进一步地，如图6所示，冷藏风道不同位置的外侧包覆有隔热件，例如包覆在冷藏送风风门外侧的风门隔热件，先沿水平方向延伸到中梁上段的风道第一段外包覆中梁风道隔热件，籍此缓解冷藏室靠近冷冻室一侧内壁的凝露现象。在本发明的其他实施方式中，还可以进一步沿着冷冻冷藏中梁向下段延伸的第二段外包覆附加隔热件，进一步缓解缓解冷藏室靠近冷冻室一侧内壁的凝露现象。
与现有技术相比，本发明一实施方式对开门冰箱具有更大的冷藏室又小容量，且有效地避免冷气泄漏。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
