Description

滚筒式洗衣干衣机 技术领域
本发明涉及一种滚筒式洗衣干衣机，其具备在旋转的脱水筒内对洗涤完的衣物进行烘干的功能。
背景技术
作为这种洗衣干衣机，例如已知专利文献1所示的洗衣干衣机。图7是表示相同现有例的立体图，图8是图7的A-A线阶梯剖面图。该洗衣干衣机在壳体1的内部配设有由门3大致密闭的外筒2，在外筒2内以未图示的大致水平的主轴为中心旋转自如地安放有周面大致圆筒形状且贯穿设置有许多通气孔4a的滚筒式的脱水筒4。
在洗涤功能中，构成向外筒2内供水的未图示的供水系统，并构成从外筒2排水的未图示的排水系统，在中低速区域对脱水筒4进行旋转驱动，由此容纳于脱水筒4内的洗涤物的捶洗、揉洗被执行。漂洗时的动作也同样。在执行清洗、漂洗后实施脱水过程时，将贮存于外筒2内的水排出至机外，通过使脱水筒4在高速区域旋转，利用离心力使渗入洗涤物中的水从洗涤物排出，穿过通气孔4a使其飞溅至外筒2侧，由排水路14进行排出。
此外，为了实现烘干功能，在外筒2的一部分形成有热风吹出部21，在该热风吹出部21形成有作为热风供给路的管道22，与吸气路23之间由波纹管状的连结管24连接。即，在该结构中，吸气路23、连结管24以及热风供给路22构成吸气风路X。此外，在吸气路23的内部，作为加热单元配设有使用了城市燃气或者丙烷气的燃气式加热器25。
另一方面，在外筒2的另一部分形成有排气部31，沿外筒2的外周面从排气部31大致笔直地朝向前方形成有排气取出路32，与排气路33之间由波纹管状的连结管37连接。排气路33的末端构成在壳体1开口的排气排出口33a。即，在该结构中，排气取出路32、连结管37以及排气路33构成排气风路Y。此外， 在排气路33的内部，作为送风单元配设有风扇36。
在烘干运转时，风扇36被旋转驱动。通过该风扇36的工作，如图8中由空心箭头所示，形成有如下气流：外部空气被吸入并经过吸气路23、连结管24、热风供给路22，从热风吹出部21供给至外筒2内，穿过外筒2内的空气从排气部31经过排气取出路32、连结管37、排气路33，从排气排出口33a向机外排出。此时，当通过加热器25进行燃气加热时，由加热器25加热后的高温空气被供给至外筒2内。然后，在外筒2内，高温空气从通气孔4a进入脱水筒4内，穿过脱水筒4内时，在所容纳的湿洗涤物与高温空气之间进行热交换，洗涤物被烘干。包含从洗涤物排出的水蒸气的湿空气穿过通气孔4a来到外筒2侧，最终从排气排出口33a向机外排出。
此外，在像这样从外筒2的侧方吹入热风的构造的洗衣干衣机中，为了高效地将热风导入脱水筒4的内部，由整流板29构成热风吹出部21的一部分，将热风的流向调整为朝向脱水筒4。整流板29最大限度地延长至脱水筒4的附近会使热风的泄漏变少，使烘干性能提高，因此，如果关注其效果，则考虑：在构成热风供给路22的管道内，最好将整流板29设置到不与脱水筒4接触的极限位置。

发明内容
发明所要解决的问题
然而，有时会在毛很长的衣物、地毯的一部分等、或者在洗涤前忘记去除的钉、金属件等异物从脱水筒4的孔飞出的状态下进行脱水。此时，在飞出的部分处于穿过与整流板29对置的位置的位置关系的情况下，在脱水中飞出的衣物、金属件等异物与整流板29连续碰撞时，整流板29会破损，进而破损后的整流板29会损伤脱水筒4、外筒2，直至导致脱水筒4的破损、外筒2的漏水的风险也不能不考虑。反过来说，在假设了这样的事情的情况下，必须将整流 板29以最小限度的距离远离脱水筒4，来提高烘干性能实际上是困难的。
根据这样的情况，迫切希望一种洗衣干衣机，其即使将整流板29尽可能接近脱水筒4来提高烘干性能，来自孔4a的衣物等的飞出也不会成为较大障碍。
本发明是着眼于这样的问题而做出的，其目的在于，实现一种以往没有的洗衣干衣机，其即使采用提高烘干性能的结构，也防止了在脱水时与来自脱水筒的飞出物产生干扰。
用于解决问题的方案
本发明为了解决以上这样的问题，采用了以下这样的方案。
即，本发明的滚筒式洗衣干衣机具备：外筒，供热风吹出部开口；滚筒式的脱水筒，旋转自如地配设于所述外筒内且在周壁设有孔；以及吸气风路，一端连接于所述外筒的热风吹出部，紧接着所述脱水筒在高旋转区域的脱水过程，实施所述脱水筒在中低速旋转区域的烘干过程，其特征在于，设置有驱动单元，所述驱动单元设置为能够使所述热风吹出部的至少一部分相对于所述脱水筒接触/分离，并且在脱水过程时使所述热风吹出部从所述脱水筒退避，在烘干过程时使所述热风吹出部接近所述脱水筒。
此外，本发明的特征在于，所述热风吹出部的一部分由将从该热风吹出部排出至所述外筒内的气流的方向调整为朝向所述脱水筒的方向的整流板构成，将该整流板设置为能够相对于所述脱水筒接触/分离，并能够由所述驱动单元驱动。
此外，本发明的特征在于，所述热风吹出部的一部分由能够相对于所述脱水筒接触/分离的可动管道构成，该管道配置于在与所述脱水筒对置的位置具有开口部的固定管道内，并能够由驱动单元驱动。
此外，本发明的特征在于，所述驱动单元利用重力将所述热风吹出部的至少一部分保持在接近位置，利用所述脱水筒的转速升高时的振动来克服重力，而将所述热风吹出部驱动至退避位置。
此外，本发明的特征在于，所述驱动单元具备：活塞，能够在气缸内升降；带轮，能够绕固定轴旋转；曲轴，一端连接于所述活塞，另一端连接于从所述带轮的固定轴偏心的位置；以及传递元件，一端连接于所述整流板，另一端缠 绕于所述带轮，所述驱动单元构成为：通过由振动实现的所述活塞的升降动作，进行所述传递元件向带轮的卷绕，或者进行由重力实现的所述传递元件从带轮的放出。
发明效果
根据以上说明的本发明，由于在脱水过程时热风吹出部通过驱动单元从脱水筒退避，因此能够避免由与衣物、异物等飞出物的干扰导致的机构零件的破损的风险，由于在烘干过程时热风吹出部通过驱动单元接近脱水筒，因此能够提高烘干性能。
此外，根据使用了整流板的本发明，整流板是在将热风从外筒的孔由适当方向导入外筒内的基础上实现功能的，通过使该整流板接触/分离，能够避免干扰，并且能够得到更高的烘干性能。
此外，根据使用了可动管道的本发明，通过使整个可动管道接触/分离，能够避免干扰，并且能够防止从固定管道吹出的热风在脱水筒与外筒之间泄漏。
此外，根据在驱动单元中利用重力以及振动的本发明，在进行向接近位置的保持和向退避位置的驱动时，不需要能量源，不会增加产品的耗电。此外，不需要电机等动力源，能够抑制零件材料费的上升。此外，特别是，也不需要控制。
此外，根据在驱动单元中利用曲柄机构的本发明，能够由简单的组成零件构成驱动单元，带轮、曲轴的配置的自由度也提高。

本实施方式的洗衣干衣机的基本结构以及作用如基于图7以及图8进行的说明，图1是本实施方式的洗衣干衣机的主要部分说明图。以下，在本实施方式中，在对与图7以及图8共同的部分的概要进行了说明的基础上，以不同的部分为中心展开说明。
该洗衣干衣机具备：外筒2，供热风吹出部21开口；滚筒式的脱水筒4，旋转自如地配设于外筒2内且在周壁设有孔4a；以及吸气风路X，一端连接于外筒2的热风吹出部21，所述洗衣干衣机控制为：接着脱水筒4的在高旋转区域的脱水过程，实施脱水筒4的在中低速旋转区域的烘干过程。
在这样的结构中，当使热风吹出部21最大限度地接近脱水筒4的附近时，会产生衣物、异物等飞出物Z与热风吹出部21的构成元件发生干扰这样的不良情况。例如，如相当于脱水筒4、外筒2、吸气风路X的一部分的图2的比较例所示，考虑如下情况：对于热风吹出部21的一部分，将从该热风吹出部21排出至外筒2内的气流的方向调整为朝向脱水筒4的方向的整流板29固定于构成热风供给路的管道22内而设置。在将热风的流向调整为朝向脱水筒4时，当使整流板29如图示那样最大限度地延长至脱水筒4的附近时，存在洗涤物、异物等飞出物Z与整流板29发生干扰的不良情况，当为了避免该情况，而将整流板29的顶端29a配置为比图示的位置更远离脱水筒4时，存在烘干性能降低这样的进退两难的困境。
因此，在图1所示的本实施方式中，设有驱动单元5，所述驱动单元5设置为能够使热风吹出部21的至少一部分相对于脱水筒4在接近位置P与退避位置Q之间接触/分离，并且在脱水过程时使热风吹出部21从脱水筒4退避，在烘干过程时使热风吹出部21接近脱水筒4。在图示例中，后述的将整流板29的顶端 29a与管道22的安装端22a连结的线相当于热风吹出部21的接近位置(P)，管道22的安装线相当于整流板29退避时的热风吹出部29的退避位置(Q)。
通过这样构成，由于在脱水过程时热风吹出部21通过驱动单元5从脱水筒4退避，因此能够避免由与衣物、异物等飞出物Z的干扰导致的热风吹出部21的构成部分即整流板29的破损的风险，由于在烘干过程时热风吹出部29通过驱动单元5接近脱水筒4，因此能够提高烘干性能。
此外，上述的整流板29构成热风吹出部29的一部分，起到将从热风吹出部29排出至外筒2内的气流的方向调整为朝向脱水筒4的方向的作用，通过将该整流板29设置为能够相对于脱水筒4接触/分离并由驱动单元5驱动，从而实现热风吹出部29的接触/分离动作。
因此，整流板29是在将热风从脱水筒4的孔4a由适当方向导入脱水筒4内的基础上实现功能的，通过使该整流板29接触/分离，能够避免干扰，并且能够实现更高的烘干性能。
该实施方式的整流板29由耐热性、耐水性、强度优异的材料(例如SUS304)构成，基端29b通过铰链H能够旋转地安装于管道22的内壁，顶端29a为自由端。整流板29在图示例中仅配置一块，但也可以根据需要配置多块。
驱动单元5构成为：利用重力将热风吹出部21的至少一部分保持在接近位置P，利用脱水筒4的转速升高时的振动来克服重力，而将热风吹出部21驱动至退避位置Q。
具体而言，驱动单元5具备：活塞52，能够在气缸51内升降；带轮53，能够绕固定轴m旋转；曲轴54，一端连接于活塞52，另一端连接于从带轮53的固定轴m偏心的位置；以及作为传递元件的金属线55，一端连接于整流板29的顶端29a，另一端缠绕于带轮53的卷绕部53a，所述驱动单元5构成为：通过由振动实现的活塞52的升降动作，进行金属线55向带轮53的卷绕，或者进行由重力实现的金属线55从带轮53的放出。气缸51和固定轴m固定于在外筒2形成的管道22的外壁，金属线55经由设于管道22的一部分的插通孔22b插通于管道22内。
以从朝向曲轴54的带轮53的连接点n从图1的位置移动并到达了下止点 的状态起，当活塞52在脱水过程时通过转速升高时的振动而上升时，向卷绕方向驱动带轮53的方式，设定连接点n的位置以及曲轴54与活塞52的连接点r的位置。卷绕部53a的直径与金属线55的长度设定为如下关系：在金属线55被放出最大时，整流板29与脱水筒4大致正交，在活塞52动作了多个行程时，整流板29与管道22的上壁22c抵接，而使金属线55的进一步卷绕被禁止。反之，设定为如下关系：在脱水过程前、或者脱水过程后，作用于整流板29的重力超过作用于活塞52、曲轴54的重力，由此活塞52上升，整流板29下降。
像这样，由于驱动单元5仅利用重力和振动，因此在进行热风吹出部21的向接近位置P的保持和向退避位置Q的驱动时，不需要能量源，不会增加产品的耗电。此外，不需要电机等动力源，能够抑制零件材料费的上升。此外，特别是也不需要控制。
此外，对于驱动单元5，能够由简单的组成零件构成驱动单元，带轮53、曲轴52的配置的自由度也提高了。
需要说明的是，整流板的接触/分离动作不限定于旋转动作，例如也可以利用如图3所示那样的进退动作。该整流板29x容纳于在管道22内配置的引导件29y内，使顶端29xa与脱水筒4对置，将基端连接于作为与图1同样的驱动单元5的传递元件的金属线55，对金属线55向带轮53的缠绕方向、曲轴54与带轮53的连接点n的位置、曲轴54与活塞52的连接点r的位置进行了调整。
即使这样构成，整流板29通过自重接近脱水筒4，此外通过转速升高时的振动使活塞52升降而进行后退，也能够与上述实施方式同样地将热风吹出部21切换至接近位置P和退避位置Q。
<第二实施方式>
接着，参照图4～图6对本发明的第二实施方式进行说明。图4的结构与图1的结构相比，主要是热风吹出部121以及驱动单元105的结构不同，其它的洗衣干衣机的结构相同，因此省略说明。
该热风吹出部121使用能够相对于脱水筒4接触/分离的可动管道106构成，该可动管道106配置于在与脱水筒4对置的位置具有开口部107a的固定管道107内，并能够由驱动单元105驱动。
固定管道107固定于外筒2，可动管道106能够旋转地安装于该固定管道107。可动管道106的开口部106a朝向脱水筒4，经由设于外筒2的窗102在接近脱水筒4的位置与从此处退避的位置之间可动。驱动单元105在此并非利用自重和振动，而构成为：采用驱动器，其输出轴对连接有可动管道106的顶端的传递元件例如杆155进行进退驱动。当然，也可以如上述第一实施方式那样，利用重力和振动来构成。
通过这样的构成，当使可动管道106接触/分离时，在可动管道106的开口部106a接近脱水筒4的图6的状态下，其开口部106a成为热风吹出部121的接近位置P，在可动管道106的开口部106a远离脱水筒4的图5的状态下，固定管道107的开口部107a成为热风吹出部121的退避位置Q，起到与上述第一实施方式一致的作用效果。
该情况下，可动管道106成为接近位置P，由此，热风不会在外筒2与脱水筒4之间泄漏，能够高效地将热风供给至脱水筒4。
以上，对本发明的实施方式进行了说明，但各部分的具体结构不仅限于上述的实施方式。
例如，本发明不仅适用于具有水平轴的洗衣干衣机，也能够同样适用于具有倾斜轴的洗衣干衣机。
其它的结构在不脱离本发明的主旨的范围内可以进行各种变形。
