参照图1至图8，对本发明的一种具体的优选实施方式进行描述。
如图1和图2所示，本发明的热泵洗烘一体机包括箱体1和设置在箱体1内的筒模块2(也可以称作外筒)和热泵模块3，热泵模块3能够向筒模块2内供应热空气，以对衣物进行烘干。
如图2至图4所示，本发明的热泵模块3包括顺次连接的第一烘干风道33、风机32和第二烘干风道31，第二烘干风道31内设置有蒸发器34，第一烘干风道33内设置有冷凝器35，筒模块2上设置有与第二烘干风道31连通的第二风口(图中未示出)和与第一烘干风道33连通的第一风口(图中未示出)。
本实施方式中，筒模块2内的湿热空气在风机32的作用下进行循环流通，经第二风口依次进入第二烘干风道31、第一烘干风道33、第一风口进入筒模块2内，在蒸发器34的作用下，使湿热空气中的水分凝结后从气流中分离，在冷凝器35的作用下，使空气的温度上升，以向筒模块2内供应热空气，实现对筒模块2内衣物的干燥，进而对衣物进行烘干。
优选地，如图1和图2所示，第二烘干风道31、风机32和第一烘干风道33均设置在筒模块2的上方。
进一步地，如图2至图4所示，第二烘干风道31包括连通的第二导流部311和第二风道312，第二导流部311和第二风道312设置在筒模块2的后上方，即靠近筒模块2的后端设置，蒸发器34设置在第二风道312内，第二风口设置在筒模块2的后上方，即第二风口也靠近筒模块2的后端设置，便于使第二导流部311与第二风口连通。第二风道312沿水平方向延伸，并且，第二风道312的延伸方向与筒模块2的轴线方向垂直。
其中，第二导流部311和第二风道312优选设置为可拆卸固定连接。
进一步地，如图2至图4所示，第一烘干风道33包括连通的第一风道331和第一导流部332，第一导流部332和第一风道331设置在筒模块2的左上方或右上方，冷凝器35设置在第一风道331内，第一风口设置在筒模块2的前上方，即第一风口靠近筒模块2的前端设置，第一导流部332与第一风口连通。第一风道331也沿水平方向延伸，并且，第一风道331的延伸方向与筒模块2的轴线方向平行，也就是说，第一风道331的延伸方向与第二风道312的延伸方向垂直，两个换热风道呈近似L形布置。
其中，第一风道331和第一导流部332优选设置为可拆卸固定连接。
本实施方式针对在箱体1内筒模块2上方空间的结构特点，具体地，以滚筒式热泵洗烘一体机为例，一般左上方前端空间内需要设置衣物处理剂投放盒，相应地，后上方和右上方具有一定的空闲空间，因此，本实施方式的热泵洗烘一体机根据箱体1内部空间的特点，将第二烘干风道31设置在后上方空间，第一烘干风道33设置在右上方，风机32设置在第二烘干风道31与第一烘干风道33之间，位于右上方的拐角处。从整体布局来看，第二烘干风道31、风机32和第一烘干风道33整体呈垂直分布，能够最大限度的利用空余空间，同时还能够保证热泵洗烘一体机的整机高度尺寸保持不变。
需要说明的是，筒模块2的前端具有衣物取放口，本领域技术人员可以将该衣物取放口当作第一风口，即使第一导流部332与该衣物取放口连通，或者，也可以如图2所示，在筒模块2的前上方单独开设一个风口作为第一风口，这种关于第一风口的具体设置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。
进一步地，为了能够在有限的空间内尽可能地提高换热效率，保证烘干效果，需要尽可能地增大蒸发器34和冷凝器35的换热主体，因此，第二风道312和第一风道331具有适配于其所在空间的外部轮廓，以使得第二风道312内所容纳的蒸发器34的换热主体和第一风道331内所容纳的冷凝器35的换热主体尽可能地增大。
具体地，如图2和图3所示，第二风道312设置在筒模块2的后上方，大致位于筒模块2的中间位置处，并且由于筒模块2为圆筒形结构，在圆筒形结构的中间位置处大致处于平面，因此，第二风道312大致呈矩形结构，即第二风道312大致呈扁平状，横截面近似矩形，相应地，其内部的蒸发器34的换热主体呈规则的矩形排布。第一风道331设置在筒模块2的右上方，为了与筒模块2的圆筒形结构相适配，并充分利用该部分空间，第一风道331设置为非矩形结构，即在该部分空间内，第一风道331设置为“7”形结构，即呈上宽下窄的结构，并且第一风道331上靠近筒模块2的面设置为内凹弧面，该内凹弧面与筒模块2共中心轴线，相应地，其内部的冷凝器35的换热主体也呈“7”形结构排布。
需要说明的是，上述所描述的第二风道312和第一风道331的形状以及分别在其内部设置的蒸发器34和冷凝器35所对应的换热主体的排布形状仅是示例性地，本领域技术人员也可以根据实际情况进行其他形状的排布，只要能够充分利用箱体1与筒模块2之间的空间，使得第二风道312和第一风道331的底部轮廓与筒模块2的筒壁轮廓相匹配，并且换热风道内部的换热主体能够最大限度地提高换热效率即可，本发明对此不作任何限制。
再进一步地，风机32设置在右上方的拐角处，为充分利用该部分空间，风机32竖向设置，风机32的进风口的中心轴线(即风机32的叶轮的轴线)沿箱体1横向水平延伸，即与筒模块2的轴线方向垂直，风机32的出风口的中心轴线(风机32的出风口的中心轴线与风机32的叶轮的轴线垂直)沿箱体1纵向水平延伸，即与筒模块2的轴线方向平行，也就是说，风机32的进风口的中心轴线的延伸方向与第二风道312的延伸方向相同，风机32的出风口的中心轴线的延伸方向与第一风道331的延伸方向相同，第二烘干风道31与风机32的进风口连通，第一烘干风道33与风机32的出风口连通，这样就使得第二烘干风道31与第一烘干风道33以风机32为中心相对呈垂直分布，能够最大限度的利用箱体1与筒模块2之间的空余空间，以进一步保证热泵洗烘一体机的整机高度尺寸保持不变。
此外，第二导流部311和第一导流部332的设置形式也是以能够满足充分利用箱体1与筒模块2之间的空间，具体地，如图1和图2所示，第二导流部311和第一导流部332均设置为弯折形结构，且靠近筒模块2的面设置为内凹弧面，与筒模块2的筒壁表面相适配。其中，第二导流部311和第一导流部332均优选采用柔性材料制成，例如采用橡胶管等。
再进一步地，第二导流部311、第二风道312、风机32、第一风道331和第一导流部332均与筒模块2的筒壁之间具有间隔，以保证与筒模块2之间的安全距离，从而保证各自正常工作。
优选地，如图2至图4所示，本发明的第二烘干风道31还包括第二导流管313，第二导流管313的第一端与第二风道312连通，第二导流管313的第二端与风机32的进风口连通。第二导流管313的口径大小自第二导流管313的第一端至第二导流管313的第二端方向逐渐收窄，以使空气能够收聚至风机32的进风口。
其中，第二导流管313的延伸方向与第二风道312的延伸方向一致。需要说明的是，第二导流管313与第二风道312可以固定连接，或者，也可以一体设置。
优选地，如图2至图4所示，本发明的第一烘干风道33还包括第一导流管333，第一导流管333的第一端与风机32的出风口连通，第一导流管333的第二端与第一风道331连通。第一导流管333的口径大小自第一导流管333的第一端至第一导流管333的第二端方向逐渐放宽，以使经风机32的出风口流出的空气能够向第一风道331内扩散。
其中，第一导流管333的延伸方向与第一风道331的延伸方向一致。需要说明的是，第一导流管333与第一风道331可以固定连接，或者，也可以一体设置。
进一步地，如图4所示，第一导流管333内设置有导流件3331，以对空气具有导流作用，使经风机32的出风口流出的空气能够向第一风道331内均匀扩散，从而使空气能够均匀流经冷凝器35，避免空气聚集在冷凝器35的某一区域，实现均匀换热，保证换热效率。
优选地，如图4所示，导流件3331设置为板状结构。
其中，导流件3331从第一导流管333的进风端一直延伸至冷凝器35的迎风端面。
需要说明的是，每个导流件3331可以是弯曲的板状结构，也可以是平直的板状结构。
优选地，如图4所示，在第一导流管333内设置有多个导流件3331，多个导流件3331沿垂直于气流的流动方向间隔分布，多个导流件3331将第一导流管333的内部分隔成多个导流通道，经风机32的出风口流出的气流能够分别经各个导流通道流经冷凝器35的换热主体，以进行均匀换热。
示例性地，如图4所示，导流件3331的数量为两个，两个导流件3331将第一导流管333的内部分隔成三个导流通道。
优选地，如图2所示，本发明的热泵模块3还包括压缩机36，压缩机36设置在筒模块2的下方。
示例性地，压缩机36竖立设置在筒模块2的左下方，当然，压缩机36也可以是卧式设置，只要能够适配安装在筒模块2与箱体1之间的下部空间内即可。压缩机36、蒸发器34和冷凝器35彼此连通构成冷媒循环回路，冷媒与流经蒸发器34的湿热空气进行换热，能够使湿热空气中的水分凝结后从气流中分离，冷媒与流经冷凝器35的空气进行换热，能够使空气的温度升高，从而向筒模块2内供应热空气。
上述实施方式及各种拓展实施例，通过对热泵模块3在热泵洗烘一体机内的分布布局进行设计，能够保证整机高度尺寸保持不变的情况下最大限度的利用空余空间，同时还在有限的空间内尽可能地提高换热效率，保证烘干效果。此外，热泵模块3中各个部件之间采用可拆卸式固定连接，尤其是蒸发器34和冷凝器35采用分体式设计，与现有的热泵模块3采用模块化设置相比，利于单独更换，节省成本。
优选地，如图4所示，本发明的第二烘干风道31上设有新风进口3122，新风进口3122位于蒸发器34与风机32之间。
通过在第二烘干风道31上设置新风进口3122，在执行烘干程序的过程中，能够将外部干燥的新风引入，有利于提高烘干效率，此外，通过将新风进口3122设于蒸发器34与风机32之间，能够引入更多的新风，且进入的新风的温度不会受到蒸发器34温度的影响，更有利于提高烘干效率。
示例性地，如图4所示，新风进口3122设置在第二导流管313上。当然，本领域技术人员也可以将新风进口3122设置在第二风道312上。
优选地，如图4所示，第一烘干风道33上设有新风出口3321，新风出口3321位于冷凝器35的下游。
衣服洗完后，如果用户没有及时地将衣物取出，可以启动风机32，压缩机36不启动，使气流在筒模块2与烘干风道内循环流动，新风从新风进口3122不断地进入，一部分气流会从新风出口3321排出，以避免筒模块2内气压过高而发生危险，此外，通过将新风出口3321设置在冷凝器35的下游，能够减少风阻且便于装配。
优选地，本发明的热泵洗烘一体机还包括排风管(图中未示出)以及安装在排风管上的电控阀，排风管的一端与新风出口3321连通，排风管的另一端与箱体1的外部连通，电控阀用于控制排风管的通断状态。
通过设置排风管与新风出口3321连通，能够将从新风出口3321排出的湿空气直接引导至箱体1的外面，避免造成箱体1内部的湿度过大，此外，当不需要通过新风出口3321排气时，电控阀处于关闭状态。
优选地，箱体1的前面板上设有排风口(图中未示出)，排风管的另一端与排风口连通。
通过在箱体1的前面板上设置排风口，排风口通过排风管与新风出口3321连通，从新风出口3321排出的空气从箱体1的前侧排出，有利于快速扩散。
优选地，本发明的热泵洗烘一体机还包括衣物处理剂投放盒和泄压管(图中未示出)，泄压管的第一端与筒模块2连通，泄压管的第二端与衣物处理剂投放盒连通，泄压管的第一端与第二端之间具有水封管段，水封管段的高度低于泄压管的第一端和第二端以在水封管段内形成水封。
其中，衣物处理剂投放盒用于投放衣物处理剂(例如洗涤剂、柔顺剂等)，在执行烘干程序的过程中，由于新风的进入，筒模块2内的压力逐渐变大，在该压力的作用下，水封管段内的水逐渐朝向泄压管的第二端移动，直至水从泄压管排出，筒模块2内气流沿着泄压管进入衣物处理投放盒内，并通过衣物处理剂投放盒排放到箱体1的外面，实现泄压。
优选地，本发明的热泵洗烘一体机还包括排水管以及与排水管连通的排水泵，排水管与筒模块2连通，热泵洗烘一体机还包括压力传感器，压力传感器用于检测筒模块2内的压力，压力传感器与排水泵通讯连接。
在执行烘干程序的过程中，通过压力传感器对筒模块2内的压力进行检测，当筒模块2内的压力超过设定上限值时，启动排水泵进行泄压。
需要说明的是，可以将压力传感器与热泵洗烘一体机的控制器通讯连接，压力传感器检测的数据传输给控制器，由控制器来进行运算分析，当筒模块2内的压力超过设定上限值时，控制器控制排水泵启动泄压。
优选地，如图1至图6所示，本发明的热泵洗烘一体机还包括过滤装置4，第二烘干风道31上设有第一插接口3121，箱体1在与第一插接口3121对应的位置设有第二插接口11，过滤装置4包括外壳43以及安装在外壳43内的过滤组件，过滤组件能够沿外壳43的长度方向相对于外壳43移动，外壳43固定安装在箱体1与第二烘干风道31之间，外壳43的两端分别与第一插接口3121和第二插接口11连通，过滤组件包括第一支架41、第二支架42以及安装在第二支架42上的滤网(图中未示出)，第一支架41和第二支架42沿外壳43的长度方向分布且可拆卸连接，第一支架41延伸至第二插接口11，第二支架42和滤网依次穿过第二插接口11和第一插接口3121伸入到第二烘干风道31内且位于蒸发器34的上游。
过滤装置4用于对第二烘干风道31内的气流进行过滤，将气流携带的线屑等杂质截留下来，通过在箱体1和第二烘干风道31上设置插接口，当需要对过滤装置4进行清理时，可以将过滤组件从第二烘干风道31和箱体1上抽出来，此外，通过将第一支架41与第二支架42设置为可拆卸连接，在将第一支架41抽出后，将第一支架41与第二支架42拆开，再将第二支架42抽出，能够减少需要的拆卸空间，便于用户拆卸，并且，也便于对第二支架42上的滤网进行清洗，另外，通过使外壳43的两端分别与第一插接口3121和第二插接口11连通，在安装过滤组件时，便于将过滤组件顺利的插入第二烘干风道31内，用户体验更佳。
示例性地，如图1至图3所示，第一插接口3121设置在第二风道312的朝向箱体1的前面板的侧壁上，第二插接口11设置在箱体1的前面板上，过滤装置4的延伸方向与筒模块2的轴线平行，这样一来，用户可以从洗烘一体机的前侧将过滤组件抽出，更加方便。
优选地，如图6至8所示，本发明的过滤装置4还包括锁销44，锁销44安装在第一支架41上，锁销44上设有第一锁止结构441，第二支架42上设有第二锁止结构4211，锁销44在处于锁止位时，第一锁止结构441与第二锁止结构4211相配合以将第二支架42与第一支架41锁定，锁销44在处于解锁位时，第一锁止结构441与第二锁止结构4211分离，以便将第二支架42与第一支架41拆卸分离。
示例性地，第一支架41上设有竖直延伸的容纳槽(图中未示出)，容纳槽的顶部呈敞口设置，锁销44安装在该容纳槽内且能够沿竖直方向上下移动以便在锁止位与解锁位之间进行切换，第一锁止结构441包括两个锁钩，两个锁钩沿竖直方向间隔分布，第二锁止结构4211包括两个设置在第二支架42的端部的两个锁孔，在锁销44的底部与容纳槽之间安装有一个复位弹簧(图中未示出)，在复位弹簧的作用下，两个锁钩分别插入相对应的锁孔内，以将第一支架41与第二支架42锁止，当需要拆卸两个支架时，向下按压锁销44，使锁钩与锁孔分离，即可将第一支架41与第二支架42拆开。
需要说明的是，第一锁止结构441和第二锁止结构4211并不限于上述介绍的锁钩与锁孔相配合的结构，例如，还可以设置为两个相对的锁钩等等，这种对第一锁止结构441和第二锁止结构4211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。

示例性地，如图6和图7所示，第二锁止结构4211设置在第一滤网架421的第二端，第一支架41靠近第二支架42的端面具有插口(图中未示出)，第一滤网架421的第二端穿过该插口伸入到第一支架41内，第二滤网架422的第二端不穿过该插口，第二滤网架422的第二端位于第一支架41的外侧，即第二滤网架422的长度小于第一滤网架421的长度。
