下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
结合图1-6所示，本申请实施例提供了一种衣物处理装置，其包括：
后筒4、内筒、主冷凝器和冷凝器延伸部，所述后筒4包括后筒内壁，所述内筒包括 内筒外壁，所述冷凝器延伸部包括所述后筒内壁与所述内筒外壁组成的空间、后筒喷淋管4-4、后筒内壁和内筒外壁，所述后筒喷淋管4-4能对所述后筒内壁、所述内筒外壁以及后筒内壁与内筒外壁组成的空间中至少之一的湿热空气进行喷水以进行冷凝换热；所述主冷凝器包括设置在所述后筒的外壁上的冷凝风道1和设置于所述冷凝风道1上的冷凝器喷淋管1-4，所述冷凝器喷淋管1-4能对进入所述冷凝风道1中的湿热空气进行喷水以进行冷凝换热。
本申请通过主冷凝器包括设置在所述后筒的外壁上的冷凝风道和设置于所述冷凝风道上的冷凝器喷淋管，使得所述冷凝器喷淋管能对进入所述冷凝风道中的湿热空气进行喷水以进行冷凝换热，并且同时还通过冷凝器延伸部包括所述后筒内壁与所述内筒外壁组成的空间、后筒喷淋管、后筒内壁和内筒外壁，所述后筒喷淋管能对所述后筒内壁、所述内筒外壁以及后筒内壁与内筒外壁组成的空间中至少之一的湿热空气进行喷水以进行冷凝换热，使得形成主冷凝器加冷凝器延伸部两个部分均同时对湿热空气进行冷凝降温的双冷凝结构，提高了除湿效率，提高了冷凝效率，有效解决了洗干一体机整体布局限制冷凝器多为空间较小的通道，不便于使蒸汽和外界水源充分接触从而导致存在冷凝效率较低的问题，合理地利用了现有空间，延长了空气循环过程中蒸汽和外接水源的接触路径，从而实现冷凝效率提升，提高了洗干机的烘干效率。
在一些实施方式中，所述后筒4上设置有第一排气口4-1和第二排气口4-2，所述冷凝风道1为具有至少三通道的通道结构，其上设置有第一吸气口1-1和第二吸气口1-2和第三排气口1-3，所述第一排气口4-1与所述第一吸气口1-1连通以能将所述后筒4内部的湿热空气导至所述冷凝风道1中，所述第二排气口4-2与所述第二吸气口1-2连通以能将所述后筒4内部的经过后筒冷凝后的空气导至所述冷凝风道1中，所述第三排气口1-3能将所述冷凝风道1中的空气输送至加热风道中。本申请还通过后筒上设置的第一排气口和冷凝风道上设置的第一吸气口，能够通过第一吸气口和第一排气口从后筒内部吸入湿热气体进入冷凝风道中，并在冷凝器喷淋管喷出的水冷凝降温的作用下进行气液分离，有效出去水分，使得气体干燥并循环进入内筒中继续烘干作用，通过第二排气口和第二吸气口，能够通过第二吸气口和第二排气口从内筒的上部吸走主要是经过冷凝换热后的空气，进入冷凝风道中，并且还通过第三排气口能够有效地将冷凝风道中的气体通过其排出至加热风道中，使得冷凝风道形成为三通道结构(三通特征冷凝器(一端连接风机、另两端连接洗衣机外筒)；冷凝器延伸部(洗衣机外筒内壁与洗衣机内筒外壁其间的夹层作为冷凝器延伸部))，有效地将将歧管与冷凝风道形成为一个整体结构。
图2是双冷凝系统的原理的另一种表达，图中可知，自电加热吹出的热风，进入滚筒 内可以简单分为3路，第一路经过冷凝风道1，进行冷凝，第二路经过后筒4，进行冷凝，最后还有一路直接经过第二排气口4-2，进入第二吸气口1-2，此流路为低效的烘干循环。
冷凝风道1其具有第一吸气口1-1和第二吸气口21-2和第三排气口1-3，其中第三排气口1-3空间位置靠上与风机蜗壳组件连接；第一吸气口1-1空间位置偏下距离第三排气口1-3较远，冷凝器喷淋管1-4位于第一吸气口1-1高位；蒸汽从第一吸气口1-1进入冷凝风道1自低位向高位流动最终由经第三排气口1-3排出冷凝风道1，过程中外界水源由冷凝器喷淋管1-4喷入与此部分蒸汽进行混合冷凝；冷凝吸出水分和外界水分会和经由第一吸气口1-1、第一排气口4-1、流入后筒4经由排水口4-5排出。
冷凝风道1的第二吸气口1-2位于第一吸气口1-1高位与第三排气口1-3靠近；后筒内4另有一部分蒸汽存在于洗衣机外筒内壁与洗衣机内筒外壁其间图上实例为外筒底部和内筒底部之间，该位置有后筒喷淋管4-4和以特殊规则排布的导水结构4-3(优选导水筋)，外界水源由后筒喷淋管4-4喷入由以特殊规则排布的导水结构4-3风流延展行程较大的过水区域与该部分蒸汽接触冷凝，冷凝吸出水分和外界水分会经由排水口4-5排出；之后该部分气体经由第二排气口4-2、第二吸气口1-2进入冷凝风道1，该部分气体中会残存少量未冷凝蒸汽在冷凝风道1中借助由冷凝器喷淋管1-4引入的外界水，进行冷凝。
在一些实施方式中，所述第一排气口4-1位于所述第二排气口4-2的下方，所述第一吸气口1-1位于所述第二吸气口1-2的下方。本申请的第一排气口位于下方，能够主要导出后筒内部的湿热蒸汽，其多数未经过后筒冷凝的换热过程，湿度较大，第二排气口位于上方，能够主要导出后筒上方经过冷凝换热后的空气，此部分气体主要为被除湿后的干空气，因此位于上方。
在一些实施方式中，将所述后筒4的后壁沿着高度方向从上至下均分为三等分，则所述第一排气口4-1位于所述后筒4的下三分之一的范围，所述第二排气口4-2位于所述后筒4的上三分之一的范围。图4为双冷凝洗干机后筒结构示意图，表明一种后筒结构。一般情况下，将后筒均分三等分，第二排气口4-2位于上三分之一处，第一排气口4-1位于下三分之一处，这样分布是因为需要较大较长的冷凝水接触面积，以增加效率。
在一些实施方式中，所述第二排气口4-2的中心线垂直于所述后筒的后筒壁设置。一般情况下第二排气口4-2的中心线垂直于后筒后筒壁，若是平行于后筒后筒壁，则有可能会出现第二排气口4-2到第二吸气口1-2之间的管路，冷凝出来的冷凝水滴落到衣物上，影响烘干，而开设与后筒后筒壁上的第二排气口冷凝出来的冷凝水则会沿着后筒内壁流下，不会打湿衣物，影响烘干，提高烘干程度。
在一些实施方式中，所述第一排气口4-1的孔径与所述第二排气口4-2的直径的比值 在2/3～4范围内。第一排气口4-1的直径与第二排气口4-2的当量直径的比值在80/120(第一优选规格)至80/20(第二优选规格)为最优，是因为，在风机转速不变的情况下，将第二排气口4-2的直径相对变大即比值变小，就会增多通过路径3的气体，无效或低效的循环增多，降低烘干效率,但是若第二排气口4-2直径相对变小即第一排气口4-1/第二排气口4-2的比值变大，则会出现通过路径2的气体减少，降低后筒冷凝的效率，从而增长烘干时间，而且第一排气口4-1/第二排气口4-2的大小还会影响通过第二排气口4-2的气体流速，若是第二排气口4-2直径相对减小，则流速过高，容易将后筒喷淋管4-4甚至是冷凝器喷淋管1-4，流出的水倒吸入风机及后端管道，经电加热喷回到滚筒，降低温度增加湿度，再次打湿衣物。考虑到内部空间的有限，第二排气口4-2的直径尺寸不能太粗，太粗会导致无效换热增大，也不能太细否则后筒冷凝的效果不佳，因此选择在2/3～4范围内能够同时保证后筒冷凝换热还能防止或减小无效换热。
在一些实施方式中，在所述后筒4的后筒壁的平面投影内，所述第一排气口4-1的中心与所述第二排气口4-2的中心沿着水平方向的长度为L，所述后筒4的直径为D，并有L/D＝0.15～0.35。第二吸气口1-2直径与第二排气口4-2一致，第一吸气口1-1与第一排气口4-1一致。一般情况下，第二吸气口1-2与第一吸气口1-1经过圆心垂直地表的两条线的水平长度距离即图中L，其中L与滚筒直径之比在0.15～0.35为宜。L过长会增大该路风道的散热面积，因为这一段管路本身不加热，过长会影响筒内温度，降低效率。过短，即第二排气口4-2开口位置水平距离更加靠近第一排气口4-1，就会降低远离第一排气口4-1一侧的后筒面积的冷凝利用率，降低烘干效率。
在一些实施方式中，所述后筒内壁上还设置有多个导水结构4-3，所述后筒4的底部还设置有排水口4-5；所述后筒喷淋管4-4从所述后筒4的外部穿设至所述后筒内壁的位置，以能将水喷淋至所述后筒内壁上。本申请的后筒喷淋管将水喷淋到后筒内壁上，能够使得湿热空气在后筒内壁上完成换热，除湿降温，有效避免了直接喷射到后筒内部而将衣物打湿等情况发生，并且增大换热面积，提高换热效率。
实施方式中后筒4由于有后筒喷淋管4-4引入外界水源和以特殊规则排布的导水结构4-3展开过水面积还借助第二排气口4-2、第二吸气口1-2、排气口1-3、风机蜗壳组件为空气路径和动力源这几个特征成为了冷凝器延伸部。合理利用整机空间，不增加整机成本的同时，延长冷凝路径、加大换热相变面积、加大循环气体流量，提高烘干效率、缩短时间、节约用电。
在一些实施方式中，当所述冷凝风道1上还设置有第三排气口1-3时，所述衣物处理装置还包括加热风道3和加热器5，所述加热风道3上具有吸气口2，所述吸气口2与所 述冷凝风道1上的所述第三排气口1-3连通，所述加热风道3的另一端能与所述内筒和/或所述后筒连通，所述加热器5设置于所述加热风道3中。
在一些实施方式中，所述加热风道3中还设置有风机6；和/或，所述衣物处理装置为洗干一体机。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
