Description

用于烘干设备的冷凝器及烘干设备 技术领域
本发明属于烘干设备技术领域,具体提供一种用于烘干设备的冷凝器及烘干设备。
背景技术
烘干设备是指能够利用热空气对衣物进行烘干的机器。烘干设备主要包括洗干一体机、干衣机或者烘干机等。
以洗干一体机为例,洗干一体机是同时具备漂洗、脱水、烘干功能于一体的智能化设备,因其具备高性价比、空间包容性强、洗烘一体省时省力等特殊优势,目前在家电市场中广受用户的欢迎。
当前,洗干一体机线屑自清洁问题仍是行业面临的一大难题。由于衣物在滚筒内不断地相互摩擦的过程中会产生线屑、绒毛等,这些线屑类杂质会随气流在系统中不断循环流动,因此会产生挂附、堵塞烘干模块各零部件的现象,长此以往会延长机器的烘干时间,形成衣物的二次污染,影响整机使用寿命,降低用户的使用体验。
现有技术多在循环风路中途设置过滤网来阻隔烘干产生的衣物线屑,但由于设置过滤网的位置的结构面积有限,过滤网对线屑的阻拦效果差。
因此,本领域需要一种新的技术方案来解决上述问题。
发明内容
为了解决现有技术中的上述问题,即为了解决现有烘干设备的过滤装置对线屑过滤效果差的问题,本发明提供了一种用于烘干设备的冷凝器,所述冷凝器包括本体,所述本体内形成有中空腔室,所述中空腔室的内壁上设置有挡水结构,以便将流入所述中空腔室的冷却水流打散;所述中空腔室的前侧壁上还设置有第一弧形结构、第二弧形结构以及位于所述第一弧形结构和所述第二弧形结构之间的分流结构;所述中空腔室的后侧壁上形成有进气口;所述中空腔室的左侧壁设置为弧形, 所述左侧壁的两端分别与所述第一弧形结构和所述后侧壁平滑地连接;所述中空腔室的右侧壁设置为弧形,所述右侧壁的两端分别与所述第二弧形结构和所述后侧壁平滑地连接;其中,所述分流结构与所述进气口相对,并且所述分流结构设置为能够将从所述进气口进入的气体分割成第一气流和第二气流,以及能够使所述第一气流和所述第二气流分别大致沿所述第一弧形结构的切向方向和所述第二弧形结构的切向方向分别进入所述第一弧形结构和所述第二弧形结构,并因此使得所述第一气流能够沿所述第一弧形结构、所述左侧壁和所述后侧壁的左侧部分旋转上升,以及使得所述第二气流能够沿所述第二弧形结构、所述右侧壁和所述后侧壁的右侧部分旋转上升。
在上述冷凝器的优选技术方案中,所述挡水结构靠近所述分流结构设置。
在上述冷凝器的优选技术方案中,所述前侧壁上设置有导水槽,所述导水槽的底端与所述挡水结构连接。
在上述冷凝器的优选技术方案中,所述挡水结构设置于所述前侧壁,所述挡水结构为三角形,且所述挡水结构的中心线与所述分流结构的中心线重合,以便使冷却水均匀地分散。
在上述冷凝器的优选技术方案中,所述挡水结构为形成在所述前侧壁上的挡水凸起。
在上述冷凝器的优选技术方案中,所述后侧壁上设置有第一弧形引导结构和第二弧形引导结构,以便使所述第一气流和所述第二气流能够分别顺利地流向所述第一弧形结构和所述第二弧形结构。
在上述冷凝器的优选技术方案中,所述分流结构左右对称地设置且所述分流结构的中心线与所述进气口的中心线重合,以便使所述第一气流和所述第二气流大致等量。
在上述冷凝器的优选技术方案中,所述分流结构包括第一弧形分流部和第二弧形分流部,所述第一弧形分流部的一端与所述第一弧形结构平滑地连接,所述第一弧形分流部的另一端与所述第二弧形分流部的一端平滑地连接,所述第二弧形分流部的另一端与所述第二弧形结构平滑地连接。
在上述冷凝器的优选技术方案中,所述进气口处设置有挡板,以减小所述进气口的进气面积。
在另一方面,本发明还提供了一种烘干设备,所述烘干设备包括上述的冷凝器。
本领域技术人员能够理解的是,在本发明的优选技术方案中,通过在冷凝器的中空腔室的侧壁上设置挡水结构,以将冷却水流打散成水花,水花既可以实现在烘干程序进行的同时冲刷中空腔室的侧壁,也可以使循环气流中的线屑溶解于水花中,并且,在前侧壁上设置有第一弧形结构、第二弧形结构以及分流结构,将中空腔室的左侧壁和右侧壁均设置为弧形,从进气口进入的气体被分流结构分割成第一气流和第二气流,第一气流和第二气流能够旋转上升。通过这样的设置,使得第一气流和第二气流在冷凝器的本体中的行程变长,从而能够提高冷却效果,并且,两股旋转上升的气流携带被打散的冷却水花,在冷凝器内形成“旋风”状水花,通过控制冷却水量,在冷凝器中形成一定液位高度的涡旋状水花,气流通过此处时线屑溶解于水花中,同时,在最易形成线屑堆积的进气口,利用不断波动的水花实时冲刷冷凝器底部,能够提高对线屑的过滤效果。
进一步地,挡水结构靠近分流结构设置。通过这样的设置,使得冷却水被打散后能够在第一时间就与两股螺旋气流相遇,能够起到更好的过滤线屑以及冷凝的效果。
进一步地,挡水结构也设置于中空腔室的前侧壁,并且,挡水结构为三角形,挡水结构的中心线与分流结构的中心线重合,使得冷却水均匀地分散。通过这样的设置,使得两股螺旋气流能够携带大致等量的冷却水花上升,除湿过滤更加均匀,进步一提高了对线屑的过滤效果以及对气流的冷凝效果。
进一步地,分流结构左右对称地设置且分流结构的中心线与进气口的中心线重合。通过这样的设置,使得第一气流和第二气流能够大致等量,这样的话,当第一气流和第二气流在靠近后侧壁的位置上相遇后,就不会相互冲散,而是能够在相互作用下,平行的朝向前侧壁流动,然后分别进入设置在前侧壁上的第一弧形结构和第二弧形结构。
进一步地,后侧壁上设置有第一弧形引导结构和第二弧形引导结构,以便使第一气流和第二气流能够分别顺利地流向第一弧形结构和第二弧形结构。通过这样的设置,在第一弧形引导结构和第二弧形引导结构的引导作用下,能够避免第一气流和第二气流直接正向冲撞,在第一气流和第二气流相遇时,第一气流的运动趋势和第二气流的运动趋势均是朝向前侧壁的,所以当第一气流和第二气流相遇后,能够相互作用,使得第一气流朝向第一弧形结构运动,第二气流朝向第二弧形结构运动。
此外,本发明在上述技术方案的基础上进一步提供的烘干设备由于采用了上述的冷凝器,因而具备上述冷凝器所具备的技术效果,相比于现有的烘干设备,本发明的烘干设备能够更好地对线屑进行过滤且烘干效率更高。

基于背景技术指出的现有洗干一体机的过滤装置对线屑过滤效果差的问题,本发明提供了一种用于洗干一体机的冷凝器及洗干一体机,旨在通过冷凝器对线屑进行过滤。
本发明的洗干一体机包括箱体,箱体内设置有滚筒、冷凝器、风机、加热器和风管,加热器安装在风管内,风管的一端与滚筒连通,风管的另一端与风机的出风口连通,风机安装在冷凝器与风管之间。
在洗干一体机执行烘干程序的过程中,在风机的作用下,空气能够在滚筒、冷凝器和加热器之间循环流动,在加热器的作用下,干燥的空气被加热成干燥的热空气,然后沿着风管进入滚筒内与湿的衣物发生热交换,并将衣物中的水分带走,形成比较潮湿的热空气,然后进入冷凝器,经过冷凝器的冷凝作用,比较潮湿的热空气中的水分被冷凝 成水,被冷凝后的空气成为相对干燥的冷空气,然后进入风管经过加热器加热成干燥的热空气后进入下一个循环,如此周而复始,直至烘干程序结束。
下面,首先参照图1和图2,对本发明的冷凝器的结构进行详细地介绍,其中,图1是本发明的冷凝器的立体示意图一;图2是本发明的冷凝器的立体示意图二。
如图1和图2所示,本发明的冷凝器包括本体1和冷却水管(图中未示出),本体1的上部设置有出气口2,本体1的下部设置有进气口3,本体1的内部形成有中空腔室,中空腔室的顶部与出气口2连通,中空腔室的底部与进气口3连通。
继续参阅图1和图2,冷凝器的本体1的上部还设置有进水口4,进水口4与中空腔室连通,冷却水管的出水端与进水口4连通。其中,进水口4可以设置在本体1的中间位置,也可以设置在本体1的左右两侧。
在洗干一体机执行烘干程序的过程中,通过冷却水管能够向冷凝器的中空腔室内提供冷却水,从滚筒排出的湿热空气从进气口3进入中空腔室内,与中空腔室内的冷却水进行热交换,湿热空气中的水分被冷凝成水,被冷凝后的空气成为相对干燥的冷空气,然后通过出气口2排出,冷却水和冷凝水从下部的进气口3排出。
接着参阅图3至图9,对设置于中空腔室内的主要结构进行详细地介绍,其中,图3是本发明的冷凝器的正视图,图4是图3中A-A截面的实施例一的剖视图;图5是图3中A-A截面的实施例二的剖视图;图6是图3中B-B截面的剖视图;图7是图3中C-C截面的剖视图;图8是本发明的冷凝器的侧视图,图9是图8中D-D截面的剖视图。
如图6至图9所示,在中空腔室的侧壁上设置有挡水结构5当流入中空腔室内的冷却水流至挡水结构5时,被打散形成水花,水花既可以实现在烘干程序进行的同时冲刷中空腔室的侧壁,也可以使循环气流中的线屑溶解于水花中,随后线屑随冷凝水从进气口3流出,最终通过排水管排出机器。
通过这样的设置,使得冷凝器在实现冷凝的基础上,还能够实现对线屑的过滤,减少线屑在烘干系统中的不断循环,“净化”携带 线屑的气流,减少线屑挂附烘干模块各零部件的现象,减轻线屑堵塞烘干风道的情况。
其中,挡水结构5可以是挡水筋、挡水块或者挡水板等,这种对挡水结构5的具体结构形式的调整和改变并不偏离本发明的原理和范围,均应限定在本发明的保护范围之内。
继续参阅图3至图6,在中空腔室的前侧壁上设置有第一弧形结构11、第二弧形结构12以及位于第一弧形结构11和第二弧形结构12之间的分流结构13,中空腔室的左侧壁14和右侧壁15均设置为弧形,左侧壁14的两端分别与第一弧形结构11和后侧壁16的左端平滑地连接,右侧壁15的两端分别与第二弧形结构12和后侧壁16的右端平滑地连接。
继续参阅图3至图6,进气口3设置在中空腔室的后侧壁16上,分流结构13与进气口3相对,通过这样的设置,使得从进气口3进入的气体正好可以撞击到分流结构13上,分流结构13能够将气流分割成两股气流,记为第一气流7和第二气流8,并且,能够使第一气流7大致沿第一弧形结构11的切向方向进入第一弧形结构11,在后续气流的推动作用下,第一气流7能够沿第一弧形结构11、左侧壁14和后侧壁16的左侧部分逆时针旋转上升,以及能够使第二气流8大致沿第二弧形结构12的切向方向进入第二弧形结构12,在后续气流的推动作用下,第二气流8能够沿第二弧形结构12、右侧壁15和后侧壁16的右侧部分顺时针旋转上升。
可以理解为,中空腔室包括两个气体通道,第一弧形结构11、左侧壁14和后侧壁16的左侧部分组成第一气体通道,第二弧形结构12、右侧壁15和后侧壁16的右侧部分组成第二气体通道,气体从进气口3进入中空腔室后,被分流结构13分割成第一气流7和第二气流8,第一气流7能够沿第一气体通道的内壁旋转上升,第二气流8能够沿第二气体通告的内壁旋转上升。
本发明的冷凝器创造性地在中空腔室的前侧壁上设置了分流结构13,通过分流结构13将从进气口3进入的气体分割成第一气流7和第二气流8,使第一气流7和第二气流8各自旋转上升,通过使第一气流7和第二气流8旋转上升,使得第一气流7和第二气流8在冷凝器的本体1中的行程变长,从而能够提高冷却效果。
此外,两股旋转上升的气流携带被打散的冷却水花,在冷凝器内形成“旋风”状水花,通过控制冷却水量,在冷凝器中形成一定液位高度的涡旋状水花,气流通过此处时线屑溶解于水花中,同时,在最易形成线屑堆积的进气口3,利用不断波动的水花实时冲刷冷凝器底部,提高对线屑的过滤效果,程序运行稳定后,进出冷凝器的冷却水量达到动态平衡。
优选地,如图7至图9所示,挡水结构5靠近分流结构13设置。通过使挡水结构5靠近分流结构13设置,使得冷却水被打散后能够在第一时间就与两股螺旋气流相遇,能够起到更好的过滤线屑以及冷凝的效果。
此外,通过这样的设置,也能够使挡水结构5远离出气口2,能够避免水花从出气口2飞溅至风机,也能够避免水花被气流携带至滚筒中导致烘干效率低。
继续参阅图4和图5,图4和图5均是图3中A-A截面的剖视图,只是图4和图5中示出了两种不同形状的分流结构13,这两种分流结构13均是本发明的优选实施方式。
需要说明的是,虽然图4中所示的分流结构13和图5中所示的分流结构13的具体形状不同,但图4中的分流结构13和图5中的分流结构13均是左右对称地设置的,并且,其中心线与进气口3的中心线重合,通过这样的设置,使得第一气流7和第二气流8能够大致等量,这样的话,当第一气流7和第二气流8在靠近后侧壁16的位置上相遇后,就不会相互冲散,而是能够在相互作用下,平行的共同朝向前侧壁流动,然后分别进入设置在前侧壁上的第一弧形结构11和第二弧形结构12。
从图4中我们可以看出,图4中所示的分流结构13包括第一弧形分流部131和第二弧形分流部132,第一弧形分流部131的左端与第一弧形结构11平滑地连接,第一弧形分流部131的右端与第二弧形分流部132的左端平滑地连接,第二弧形分流部132的右端与第二弧形结构12平滑地连接。从进气口3进入的气体撞击到该分流结构13上,被分割成第一气流7和第二气流8,第一气流7沿第一弧形分流部131流向第一弧形结构11,第二气流8沿第二弧形分流部132流向第二弧形结构12。
从图5中我们可以看出,图5中的分流结构13为第一弧形结构11的右端部与第二弧形结构12的左端部共同组成的结构。从进气口3进入的气体撞击到该分流结构13上,被分割成第一气流7和第二气流8,第一气流7直接流入第一弧形结构11,第二气流8直接流入第二弧形结构12。
继续参阅图6,中空腔室的后侧壁16上设置有第一弧形引导结构161和第二弧形引导结构162,在第一弧形引导结构161的引导作用下,第一气流7能够顺利地流向第一弧形结构11,同样地,在第二弧形引导结构162的引导作用下,第二气流8也能够顺利地流向第二弧形结构12。
通过这样的设置,在第一弧形引导结构161和第二弧形引导结构162的引导作用下,能够避免第一气流7和第二气流8直接正向冲撞,在第一气流7和第二气流8相遇时,第一气流7的运动趋势和第二气流8的运动趋势均是朝向前侧壁的,所以,当第一气流7和第二气流8相遇后,能够相互作用,使得第一气流7能够顺利地朝向第一弧形结构11运动,第二气流8能够顺利地朝向第二弧形结构12运动。
需要说明的是,为了保证第一气流7和第二气流8能够各自独立地旋转上升,可以在中空腔室内设置一个中隔板,中隔板的前侧分别与第一弧形结构11和第二弧形结构12平滑地连接,中隔板的后侧分别与后侧壁16的左侧部分和右侧部分平滑地连接。通过设置中隔板,可以将中空腔室分割成两个腔室,第一气流7能够沿着左侧腔室的内壁旋转上升,第二气流8能够沿着右侧腔室的内壁旋转上升。
继续参阅图6至图9,在中空腔室的前侧壁上还设置有导水槽17,导水槽17的顶端与进水口4连接,导水槽17的底端与挡水结构5连接。在洗干一体机执行烘干程序的过程中,通过冷却水管向中空腔室内供应冷却水,冷却水进入导水槽17后,沿着导水槽17向下流动,当冷却水流至挡水结构5上时被打散成水花。
优选地,如图6至图9所示,挡水结构5也设置于中空腔室的前侧壁,并且,挡水结构5为三角形,挡水结构5的顶端对准导水槽17的底端,挡水结构5的中心线与分流结构13的中心线重合,使得冷却水均匀地分散。
通过这样的设置,使得两股螺旋气流能够携带大致等量的冷却水花上升,除湿过滤更加均匀,进步一提高了对线屑的过滤效果以及对气流的冷凝效果。其中,挡水结构5优选为形成在前侧壁上的挡水凸起。
优选地,如图1和图3所示,进气口3处设置有挡板6,以减小进气口3的进气面积。示例性地,挡板6的数量为两个,分别位于进气口3的左右两侧。
通过设置挡板6减小进气口3的进气面积,气流经过此处时,流道截面极速收窄,气流速度增大,为双旋转上升的气流提供更大的动量,从而提升气流盘旋高度。
至此,已经结合附图所示的优选实施方式描述了本发明的技术方案,但是,本领域技术人员容易理解的是,本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
