Description

用于制冷系统的储液器及冰箱 技术领域
本发明涉及家电技术领域，特别是涉及一种用于制冷系统的储液器及冰箱。
背景技术
冰箱的制冷系统是由压缩机、冷凝器、过滤器、毛细管、蒸发器、回气管等主要部件和一些管道连接而成。冰箱的储液器设计在蒸发器和回气管之间，一是使制冷剂气液分离，液体制冷剂先储存在储液器中，保证回到压缩机的是气体，防止压缩机发生液击，二是储存一定量的液体制冷剂，根据环境温度，调节用于制冷系统循环的制冷剂量。
现有储液器设计是在储液器进气管底部设有回油孔，当制冷剂和压缩机油混合物进入储液器后，油品因为比重大下沉到储液包底部，气态制冷剂经过出气管回到压缩机重新进入制冷循环。压缩机油会在进气管内的气流冲击作用下进入储液器上部吸入压缩机内部润滑。但是，由于压缩机油品比重大，压缩机油品不能完全充分的回到压缩机。其次，压缩机回油孔开在制冷剂液面以下，导致回油孔内也会有制冷器气泡冲出，造成气吹液现象，产生噪音。进一步地，上述储液器内的液态制冷剂气化效率也比较低。
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用于制冷系统的储液器及冰箱。
本发明一个进一步的目的是要提高储液器内的液态制冷剂气化效率，进而提高冰箱的制冷效率。
本发明另一个进一步的目的是要提高压缩机油品的回收效率。
本发明另一个进一步的目的是要减少储液器产生的噪音。
特别地，本发明提供了一种用于制冷系统的储液器，包括：筒体，其内限定有气液分离腔；进气管，用于连接制冷系统的蒸发器的蒸发管，并从筒体的一端伸入气液分离腔，并且进气管伸入气液分离腔的一端设置有与进气管的管口相对的挡片，从而使得进气管排出的混合物撞击挡片后从挡片和进气管之间的间隔排入气液分离腔。
进一步地，储液器还包括：多个支撑筋，从进气管伸入气液分离腔的一端沿进气管的延伸方向伸出；并且挡片固定连接于支撑筋上，以利用多个支撑筋形成挡片和进气管之间的间隔。
进一步地，进气管伸入气液分离腔的部分随伸入长度的增加其管径渐缩。
进一步地，储液器还包括：排气管，其从筒体的另一端伸入气液分离腔，并且排气管的伸入气液分离腔的一端与挡片之间具有设定的间隔。
进一步地，排气管伸入气液分离腔的长度小于进气管伸入气液分离腔的长度。
本发明还提供了一种冰箱，该冰箱包括蒸发器以及上述任一项所述的储液器，储液器与蒸发器的蒸发管相连。
进一步地，冰箱还包括：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；蒸发器整体呈扁平长方体状，布置于冷却室的前部；储液器设置于蒸发器的后部。
进一步地，储液器从具有进气管的一端起始倾斜向上设置。
进一步地，蒸发器为翅片蒸发器，其包括：一组翅片，沿箱体的前后方向平行设置；蒸发管，穿设于翅片之间；支撑端板，设置于翅片的两侧；蒸发管的出口设置于一侧支撑端板的后部，并弧形延伸至储液器。
进一步地，蒸发器相对于水平方向沿冰箱的进深方向倾斜放置，倾斜方向为从前至后向上，并且冰箱还包括：风道盖板，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，并且风道盖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；离心风机，整体倾斜地设置于蒸发器的后侧，并用于促使形成从冷却室前方的空气经由蒸发器排向送风风道的制冷气流，并且离心风机的进风口的中心至底部内胆两侧侧板的距离不同，进风口的中心至底部内胆靠近于蒸发管的出口一侧侧壁的距离大于至底部内胆远离于蒸发管的出口一侧侧壁的距离。
本发明的用于制冷系统的储液器及冰箱，由于在储液器内与进气管相对的位置设置有挡片，因此进气管排出的制冷剂在撞击挡片后雾化，雾化后的液态制冷剂可以更加快速的气化，从而提高储液器内的液态制冷剂气化效率，进而提高冰箱的制冷效率，而且避免了液态制冷剂进入压缩机，对压缩机产生不利影响。
进一步地，本发明的用于制冷系统的储液器及冰箱，通过进气管相对的位置设置有挡片，使得进气管排出的压缩机油品在撞击挡片后雾化，雾化后的油品也会更有效率的返回到出气管进入压缩机，实现压缩机有效润滑，提高油品的回收效率。
进一步地，本发明的用于制冷系统的储液器及冰箱，减少了位于进气管底部的回油孔的设计，从而避免了制冷剂气泡通过回油孔冒出，进而减少了储液器产生的噪音。
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

具体实施方式
在本实施例的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“水平”、“底”、“进深”等指示的方位或位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。
本实施例首先提供了一种用于制冷系统的储液器100，该储液器100可以包括筒体110和进气管130。筒体110内限定有气液分离腔120。进气管130用于连接制冷系统的蒸发器220的蒸发管222，并从筒体110的一端伸入气液分离腔120，并且进气管130伸入气液分离腔120的一端设置有与进气管130的管口相对的挡片140，从而使得进气管130排出的混合物撞击挡 片140后从挡片140和进气管130之间的间隔排入气液分离腔120。
一般性地，制冷系统还可以包括压缩机250、冷凝器260、过滤器270、节流元件280，其中节流元件280可以是毛细管。由于制冷系统的工作原理是本领域技术人员所公知的，在此不做赘述。本实施例的方案中储液器100设置在压缩机250与蒸发器220之间，将从蒸发器220流向压缩机250的制冷剂进行气液分离，避免液态制冷剂进入压缩机250从而影响压缩机250的正常工作。
本实施例的方案通过设置挡片140，使得从进气管130排出的混合物与挡片140发送撞击，从而促使混合物雾化。本实施例中的从进气管130内排出的混合物是制冷剂和压缩机油品的气液混合物，混合物中的制冷剂液体与挡片140碰撞发生雾化，雾化后的液态制冷剂可以更加快速的气化，从而提高了储液器100内的液态制冷剂的气化效率，进而提高了冰箱10的制冷效率，同时避免了液态制冷剂进入压缩机250对压缩机250产生不利影响。
进一步地，本实施例中的混合物中的压缩机油品与挡片140撞击发生雾化，雾化后的压缩机油品更容易被气流的带动进入压缩机250，从而实现压缩机250的有效润滑，提高油品的回收效率。
储液器100还可以包括多个支撑筋150。多个支撑筋150从进气管130伸入气液分离腔120的一端沿进气管130的延伸方向伸出。并且挡片140固定连接于支撑筋150上，以利用多个支撑筋150形成挡片140和进气管130之间的间隔。
本实施例的方案通过设置多个支撑筋150共同作用，将挡片140固定在与进气管130管口相对的位置，从而使得挡片140的结构位置更加稳定，在进气管130排出的气流的冲击下，挡片140依然能够保持在固定位置，进而保证从进气管130排出的混合物的有效雾化。
进气管130伸入气液分离腔120的部分可以随伸入长度的增加其管径渐缩。本实施例的方案通过将进气管130伸入气液分离腔120的部分设置成随伸入长度的增加其管径渐缩，即将进气管130设置为锥形管，使得从进气管130排出的混合物气流与挡板发生碰撞时的撞击力度更大，从而提高混合物的雾化效果。
储液器100还可以包括排气管160。排气管160从筒体110的另一端伸入气液分离腔120，并且排气管160的伸入气液分离腔120的一端与挡片140 之间具有设定的间隔。
本实施例中的排气管160将进入气液分离腔120的制冷剂气流送入压缩机250，将排气管160设置为其伸入气液分离腔120的一端与挡片140之间具有设定的间隔，从而便于气态制冷剂进入排气管160。进一步地，由于排气管160与挡片140之间存在间隔，即排气管160与进气管130之间存在一定的距离，当储液器100内存储有大量的液态制冷剂时，过量的液态制冷剂会从进气管130管口处回流至蒸发器220，从而保证沉积在储液器100内的液态制冷剂不会进入排气管160，进而避免了液态制冷剂进入压缩机250后对压缩机250的运行产生不利影响。
排气管160伸入气液分离腔120的长度可以小于进气管130伸入气液分离腔120的长度。本实施例的方案中，储液器100内的液态制冷剂的液面的最高位置为进气管130的管口位置，当液态制冷剂过多时，液态制冷剂会从进气管130的管口处回流。也就是说，排气管160伸入气液分离腔120的长度越大，储液器100内可以存储的液态制冷剂越多，通过设置排气管160伸入气液分离腔120的长度小于进气管130伸入气液分离腔120的长度，可以保证储液器100内有较大的液态制冷剂的存储空间，当储液器100内雾化的制冷剂达到饱和时，会自然的凝聚成液态囤积在储液器100底部，将过剩的制冷剂储存。通过在储液器100内储存一定量的液体制冷剂，可以根据环境温度，调节用于制冷系统循环的制冷剂量，当环境温度降低时，参与系统循环的制冷剂减少，储液器100可以将过量的制冷剂储存起来；当环境温度升高时，系统需要较多的制冷剂循环量，储液器100储存的制冷剂又参与制冷循环，使冰箱10在不同环境温度下都能获得较好的制冷效果。
本实施例还提供了一种冰箱10，该冰箱10可以包括蒸发器220以及上述的任意一种的储液器100。该储液器100与蒸发器220的蒸发管222相连。
本实施的方案通过设置储液器100与蒸发器220的蒸发管222相连，从而使得通过蒸发管222从蒸发器220流入储液器100的制冷剂气液分离，液体制冷剂先储存在储液器100中，保证回到压缩机250的是气体，防止压缩机250发生液击。
本实施例的冰箱10还可以包括箱体200。箱体200具有底部内胆210，底部内胆210限定有冷却室212和储物空间211，冷却室212设置于储物空间211的下方。蒸发器220整体呈扁平长方体状，布置于冷却室212的前部。 储液器100设置于蒸发器220的后部。箱体200前侧还设置有门体，以打开或关闭储物空间211，为了示出箱体200内部结构，图中隐去了门体。
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。本实施例中的底部内胆210指位于冰箱10最下方的内胆。
在本实施例中，位于冰箱10底部的底部内胆210通过分隔板213限定出储物空间211以及位于储物空间211的下方的冷却室212。其中，底部内胆210限定的储物空间211可以为冷冻间室。此外，储物空间211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。
储液器100从具有进气管130的一端起始倾斜向上设置。本实施例的方案中储液器100倾斜设置的角度可以为10度到35度，通过将储液器100设置为从具有进气管130的一端起倾斜向上设置，一方面更贴合底部内胆210的形状，占用冷却室212的空间小，提高了冷却室212的空间利用效率，另一方面，储液器100倾斜设置，便于储液器100内存储的过量液态制冷剂回流到蒸发器220，从而进一步保证了储液器100内沉积的液态制冷剂不会进入排气管160。
蒸发器220为翅片蒸发器，该翅片蒸发器可以包括：一组翅片、蒸发管222和支撑端板221。一组翅片沿箱体200的前后方向平行设置。蒸发管222穿设于翅片之间。支撑端板221设置于翅片的两侧。蒸发管222的出口设置于一侧支撑端板221的后部，并弧形延伸至储液器100。
本实施例的方案采用了翅片蒸发器，不仅结构紧凑、占用面积小，而且其传热系数高，从而进一步提高了蒸发器220的换热效率，并保障了冰箱10的制冷存储功能。
蒸发器220相对于水平方向沿冰箱10的进深方向倾斜放置，倾斜方向为从前至后向上，并且冰箱10还可以包括风道盖板230和离心风机240。风道盖板230设置于底部内胆210的后壁的前方，并与底部内胆210的后壁限定出送风风道，并且风道盖板230开设有至少一个送风口231，送风口231用于连通送风风道以及储物空间211。离心风机240整体倾斜地设置于蒸发器220的后侧，并用于促使形成从冷却室212前方的空气经由蒸发器220排向送风风道的制冷气流，并且离心风机240的进风口241的中心至底部内胆 210两侧侧板的距离不同，进风口241的中心至底部内胆210靠近于蒸发管222的出口一侧侧壁的距离大于至底部内胆210远离于蒸发管222的出口一侧侧壁的距离。
现有技术中的蒸发器底置式冰箱，蒸发器水平放置，当气流进入冷却室容易在蒸发器的前端发生聚集现象，不能流畅的进入蒸发器换热。而本实施例的蒸发器220倾斜放置，使得冷却室212内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。
本实施例的方案通过在底部内胆210的后部设置风道盖板230和离心风机240，从而提高制冷空气从冷却室212流入储物空间211的流通速率，进一步保障冰箱10的制冷存储效果。本实施例的方案中送风口231可以设置为一个或多个，如图3所示的一个实施例中，风道盖板230上设置有4个送风口231，使得送风更加均匀、流畅。
实施例的方案中采用了离心风机240，其运行平稳，维护方便，且坚固耐用。进一步地，本实施例中的离心风机240设置为进风口241的中心至底部内胆210靠近于回气管170一侧侧壁的距离大于至底部内胆210远离于回气管170一侧侧壁的距离，也就是说，送风风机的进风口241的中心偏向于底部内胆210的左壁，即送风风机设置于底部内胆210偏向于左侧的位置，使得制冷空气从风机的出风口向送风风道内的流通更加顺畅，从而进一步提高风机地送风效率。上述离心风机240的安装位置的设置是根据空间要求以及制冷性能要求做出的结构优化，并且得到试制产品的效果验证。
本实施例的方案通过在储液器100内与进气管130管口向相对的位置设置挡片140，使得从进气管130排出的混合物与挡片140发送撞击，从而促使混合物雾化。一方面，混合物中的制冷剂液体与挡片140碰撞发生雾化，雾化后的液态制冷剂可以更加快速的气化，从而提高了储液器100内的液态制冷剂的气化效率，进而提高了冰箱10的制冷效率，同时避免了液态制冷剂进入压缩机250对压缩机250产生不利影响。另一方面，混合物中的压缩机油品与挡片140撞击发生雾化，雾化后的压缩机油品更容易被气流的带动进入压缩机250，从而实现压缩机250的有效润滑，提高压缩机油品的回收效率。
进一步地，本实施例的方案减少了位于进气管130底部的回油孔的设计，从而避免了制冷剂气泡通过回油孔冒出，进而减少了储液器100产生的噪音。
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。
