Description

洗干一体机 技术领域
本发明涉及一种洗干一体机。
背景技术
作为现有的洗干一体机，有一种洗干一体机(例如，参照专利文献1)具有：外筒；大致圆筒形的滚筒，自由旋转地配置在外筒内；吸气管道(未图示)，配置于外筒的周面壁的右上部；以及第一排气管道，配置于外筒的周面壁的左上部。在第一排气管道的上方设有与第一排气管道连通的第二排气管道，在第二排气管道的内部配置有风扇和过滤器。
在洗干一体机中进行烘干过程时，通过驱动风扇，将用于烘干洗涤物的空气从吸气管道供给向外筒内，并且将外筒内的空气从排气管道排出。流入第二排气管道内的空气中所含的尘埃、棉绒(线屑、绒毛等)被过滤器捕获。
在现有的洗干一体机中，第一排气管道形成为具有正面、背面、上表面、左侧面以及由外筒的周面壁构成的下表面并沿前后方向延伸的中空大致棱柱形。在洗干一体机的烘干过程中，从流入口流入第一排气管道的空气撞到与流入口对置的第一排气管道的后部的上部内周面上，而上部内周面形成于上表面和背面垂直地连接的上部角部，空气中所含的尘埃等容易蓄积在上部角部。因此，需要进行通过手动作业来去除蓄积在排气管道的内周面的尘埃等的维护。
此外，现有的洗干一体机中有一种洗干一体机，其运转模式具备滚筒洗净模式，能在洗涤运转前实施滚筒洗净模式下的运转，而该洗干一体机一般通过通常洗涤时的滚筒转速(例如40～45rpm)的搅拌力来进行滚筒内的洗净。因此，滚筒洗净时的水流不到达第一排气管道的上部角部，因此难以去除蓄积在第一排气管道的上部角部的尘埃等。

用于解决问题的方案
本发明的洗干一体机的特征在于，具备：外筒；大致圆筒形的滚筒，自由旋转地配置在所述外筒内；以及排气管道，经由形成于所述外筒的上部周面壁的流入口与所述外筒内连通，运转模式具备对所述排气管道的内部进行洗净的排气管道洗净模式。
优选的是，在本发明的洗干一体机中，所述流入口配置于在主视观察时相对于所述滚筒的旋转轴向左右方向的任一方偏心的位置，所述排气管道是配置为从正面侧朝向背面侧延伸且其一端侧与流入口对置的中空的箱状构件，在所述排气管道洗净模式下，以所述滚筒的上端部在所述外筒的上部周面壁附近从所述流入口不偏心的一侧朝向所述流入口偏心的一侧移动的方式，所述滚筒绕规定旋转方向被旋转驱动。
优选的是，在本发明的洗干一体机中，运转模式还具有用于对所述滚筒内部进行洗净的滚筒洗净模式，在所述排气管道洗净模式下，所述滚筒以大于所述滚筒洗净模式下的转速的转速被旋转驱动，并且向所述外筒内供水的水量多于所述滚筒洗净模式下向所述外筒内供水的水量。
优选的是，在本发明的洗干一体机中，所述排气管道洗净模式包括：第一排气管道洗净模式，是向所述外筒内供水的水量为第一水量的模式；以及第二排气管道洗净模式，在所述第一排气管道洗净模式之后实施，是向所述外筒内供水的水量为多于所述第一水量的第二水量的模式。
发明效果
根据本发明，即使在从外筒流入排气管道的空气中所含的尘埃等蓄积于排气管道的内周面的情况下，也能通过在排气管道洗净模式下进行运转来使水从外筒流入排气管道来去除蓄积在排气管道的内周面的尘埃等。由此，维护性提高，通过手动作业来洗净排气管道的内部的必要性降低。由此，能抑制由于尘埃等附着于排气管道使得排气量降低而导致的烘干性能降低、排气风量减少所引起的故障等发生，能减少通过手动作业对排气管道内进行清扫的次数。
根据本发明，在排气管道洗净模式下，外筒内的水流入排气管道内后，容易蓄于排气管道内。因此，在排气管道洗净模式下，能通过从外筒流入排气管道的水来去除蓄积在排气管道的内周面的大范围内的尘埃等。
根据本发明，在排气管道洗净模式下，容纳于外筒的内部的水量多于滚筒洗净模式的水量，并且滚筒的转速大于滚筒洗净模式下的转速，因此较多的水从外筒流入排气管道，能有效地去除蓄积在排气管道的内周面的尘埃等。
根据本发明，在排气管道洗净模式下，首先，能在排气管道内的水位低的状态下使排气管道的内部产生激烈的水流从而将尘埃等从排气管道的内周面除去后，在排气管道内的水位高的状态下使排气管道的内部产生平缓的水流从而冲洗掉从排气管道的内周面除去的尘埃等。

具体实施方式
以下，基于附图对本发明的实施方式的洗干一体机1进行详细说明。
(第一实施方式)
图1是本发明的实施方式的洗干一体机1的主视图。图1中，图示出卸除了正面板的一部分的状态以便理解箱体2内的结构。图2是从前方右斜上方观察洗干一体机1的内部结构的图。图3的(a)是从前方左斜上方观察图1的洗干一体机1的内部结构的图，图3的(b)是从左方观察图1的洗干一体机1的内部结构的图。需要说明的是，图3的(a)中省略了洗干一体机1的内部结构的一部分的图示。图4是从左侧方观察用沿前后方向的铅直面将洗干一体机1剖切时的剖面的概略剖视图。
如图1所示，本实施方式的洗干一体机1是投币洗衣店等中使用的商用的洗干一体机，由稍微竖长的箱体2构成外壳。
在箱体2内的大致中央部设有外筒3。外筒3蓄留从外部的供水设备等供给来的水，形成为沿大致水平的方向延伸的圆筒形。外筒3的中央部开口为圆形，其开口部分形成为用于投入取出洗涤物的外筒出入口6。
在箱体2的前表面的大致中央部，与外筒出入口6对应地形成有与外筒出 入口6同心圆状的稍微大于外筒出入口6的圆形的开口10。在开口10自由开闭地装接有作为供用户投入取出洗涤物时打开的开闭门的门11。门11还兼用作后述的滚筒5的洗涤物出入口22的门。
在箱体2的背面具备与外部的供水设备等连接的供水口12，供水口12与外筒3通过供水管13连接。通过将安装于供水管13的中途部的供水阀15设为“开”，从供水口12经由供水管13供给来的水向外筒3流入而蓄于外筒3内。
在外筒3的最下部形成有排水口16，在排水口16连接有排水管17。通过将安装于排水管17的中途部的排水阀18设为“开”，蓄于外筒3的水经由排水管17排出至机外。
在外筒3内配置有容纳洗涤物的滚筒5。滚筒5形成为圆筒形，设置为以中心轴N为中心自由旋转。滚筒5具有形成于其前表面中央部的用于投入取出洗涤物的洗涤物出入口20。在滚筒5的周面壁，几乎遍及整周地穿孔有许多孔5a，滚筒5的内部经由该孔5a与外筒3连通。由此，例如，在清洗过程时蓄于外筒3的水会经过孔5a也流入滚筒5内。
在滚筒5的后表面壁具备沿着中心轴N向后方突出的旋转轴30。旋转轴30的中央部由外筒3的轴承31保持为自由旋转，在旋转轴30的后端部安装有滚筒带轮32。
在外筒3的后方靠下处配置有用于对滚筒5进行旋转驱动的马达33。用于传递马达33的驱动力的驱动轴34自由旋转地设置于马达33。驱动轴34朝向前方延伸，在其前端部安装有马达带轮35。并且，在滚筒带轮32与马达带轮35之间以规定的张力卷绕有带36，当马达33驱动时，其驱动力经由马达带轮35、带36以及滚筒带轮32传递至旋转轴30，滚筒5旋转。
在外筒3的周面壁的右上部设有第一吸气管道50。在第一吸气管道50的下表面(外筒3的周面壁的外周面)的中央部稍微靠前处，形成有大致长方形的流入口51，吸气管道50经由流入口51与外筒3连通。在第一吸气管道50的上表面后部形成有圆形的吸气管道流入口52。
在第一吸气管道50的上方设有第二吸气管道53。第二吸气管道53由未图示的固定构件固定于箱体2。在第二吸气管道53的靠前的下端部形成有吸气管 道流入口54，与机外连通。在第二吸气管道53的与形成有吸气管道流入口54的那一侧相反侧的另一端的下端部，形成有圆形的吸气管道流出口55。第一吸气管道50的吸气管道流入口52与第二吸气管道53的吸气管道流出口55通过吸气管道连结管56连结。
在第二吸气管道53的内部配置有气体燃烧器(gas buner)57。气体燃烧器57例如是使从外部的气体供给路(未图示)供给来的气体燃烧并通过其燃烧热来加热周围的空气的气体燃烧器，通过将该气体燃烧器57设为接通来加热第二吸气管道53内的空气。就是说，在烘干过程时，通过气体燃烧器57的加热来生成用于烘干洗涤物的加热空气。
在外筒3的周面壁的左上部设有第一排气管道60。第一排气管道60具备：正面、背面、上表面、左侧面以及由外筒3的周面壁构成的下表面，是沿前后方向延伸的中空的箱状构件。像这样，第一排气管道60是配置为从正面侧朝向背面侧延伸且其背面侧与流入口61对置的中空的箱状构件。
在第一排气管道60的下表面(外筒3的周面壁的外周面)的后部形成有大致长方形的流入口61，第一排气管道60经由流入口61与外筒3连通。此外，在第一排气管道60的上表面形成有圆形的排气管道流出口62。
在第一排气管道60的上方设有第二排气管道63。第二排气管道63由未图示的固定构件固定于箱体2，在第二排气管道63的靠前的下端部形成有排气管道流入口64。第一排气管道60的排气管道流出口62与第二排气管道63的排气管道流入口64通过排气管道连结管65连结。
此外，在第二排气管道63的与形成有排气管道流入口64的那一侧相反侧的另一端的上端部，形成有排气管道流出口66。排气管道流出口66从箱体2的上表面向外部突出，外筒3与机外经由第一排气管道60、排气管道连结管65以及第二排气管道63连通。
在第二排气管道63的内部配置有风扇67。风扇67例如在烘干过程时被驱动，用于使滚筒5和外筒3内的空气从排气管道流出口66向机外流出。
此外，在第二排气管道63的内部，在风扇67与排气管道流入口64之间设有过滤器68。过滤器68设为从前侧朝向后侧往斜上侧倾斜而将第二排气管道 63内部划分为排气管道流入口64侧和风扇67侧，捕获来自排气管道流入口64的空气中所含的尘埃、棉绒(线屑、绒毛等)。
在第二排气管道63的正面形成有使第二排气管道63内部向前方连通的操作开口部8，在箱体2的正面壁的与操作开口部8对置的位置开口有操作窗8a。操作开口部8和操作窗8a始终由盖8b闭塞，当操作盖8b来打开操作开口部8和操作窗8a时，第二排气管道63内部向正面露出，能进行过滤器68的维护等。
如图5所示，本实施方式的洗干一体机1中，运转模式具有：洗涤物洗净模式，用于洗净容纳于滚筒5内的洗涤物；滚筒洗净模式，用于在洗涤物的洗净运转前洗净滚筒5的内部；以及排气管道洗净模式，用于洗净第一排气管道60的内部。
(洗涤物洗净模式)
洗涤物洗净模式进行与对如图6的(a)所示设于箱体2的操作部80的操作相应的运转模式下的运转。在本实施方式的洗干一体机1中，在洗涤物洗净模式下，例如以40～45rpm的滚筒转速对滚筒5进行旋转驱动。洗涤物洗净模式下的供水量(向外筒3内的供水量)可以适当设定为与对操作部80的操作相应的水量。
(滚筒洗净模式)
在门11关闭的状态下按下设于箱体2的滚筒洗净按钮81的情况下开始滚筒洗净模式下。假设在门11打开的状态下，在按下设于箱体2的滚筒洗净按钮81的情况下，会播放“请将门关闭后再按下”的声音。
在滚筒洗净模式下，向外筒3内供给低水量(在标准设定下为水位3度，但能设定为水位2～5度)的水，滚筒5以交替反复进行左旋转和右旋转的方式按标准设定旋转2分钟(也能设定为1～5分钟)。在滚筒洗净模式下，例如以40～45rpm的滚筒转速旋转驱动滚筒5。像这样，在本实施方式的洗干一体机1中，在滚筒洗净模式下，以与洗涤物洗净模式下的转速大致相同的转速对滚筒5进行旋转驱动。
在此，对向外筒3内供水的水量进行说明。如图7所示，在滚筒5停止的状态下，将滚筒5的下端所配置的水平高度设为0度，将滚筒5的中心所配置 的水平高度设为10度，并对两者之间进行十等分而将这些水平高度分别设为1度～9度。因此，例如，在滚筒洗净模式下，在供给水位3度的水的情况下，呈仅在比滚筒5的高度方向1/4的水平高度靠下方处有水的状态。
(排气管道洗净模式)
在门11打开的状态下将设于箱体2的滚筒洗净按钮81长按操作10秒后，在门11关闭的情况下开始排气管道洗净模式。需要说明的是，在本实施方式的洗干一体机1中，仅限于在存储于其内部的维护洗净运转次数已重置的状态下通过上述的操作开始排气管道洗净模式。
如图6的(a)所示，在箱体2的正面上部设有正面板82。正面板82能通过将专用钥匙插入形成于该正面板82的下端部的锁孔83来解锁，并能通过以正面板82的上端为支点向上方旋转来打开。如图6的(b)所示，当打开正面板82时，重置按钮84成为能够操作的状态，在对重置按钮84进行了操作的情况下，维护洗净运转次数会重置。
像这样，只要洗干一体机1的所有者不使用专用钥匙打开正面板82，就无法重置维护洗净运转次数。因此，洗干一体机1的所有者以外的人员无法在排气管道洗净模式下的运转已结束的状态下接着实施排气管道洗净模式下的运转。
在本实施方式的洗干一体机1中，排气管道洗净模式通第一排气管道洗净模式和在第一排气管道洗净模式之后实施的第二排气管道洗净模式这两种运转来实施。
在第一排气管道洗净模式下，向外筒3内供给中水量(水位6度)的水，滚筒5以管道洗净转速绕左旋转方向旋转2分钟。需要说明的是，第一排气管道洗净模式的供水量不限于水位6度，只要水位为例如5～7度，第一排气管道60内就容易产生水流。
需要说明的是，排气管道洗净模式下的管道洗净转速根据滚筒5的直径来设定。例如在洗干一体机1的滚筒5的直径为600mm的情况下，管道洗净转速设定为90～130rpm，优选设定为120rpm左右。此外，在洗干一体机1的滚筒5的直径为800mm的情况下，管道洗净转速设定为60～100rpm，优选设定为80rpm 左右。像这样，第一排气管道洗净模式下的滚筒5的转速大于滚筒洗净模式下的滚筒5的转速。
在本实施方式的洗干一体机1中，流入口61配置于在主视观察时相对于滚筒5的旋转轴向左方向偏心的位置，在排气管道洗净模式下，以滚筒的上端部在外筒3的上部周面壁附近从右侧(流入口61不偏心的一侧)朝向左侧(流入口61偏心的一侧)移动的方式，滚筒5绕左旋转方向被旋转驱动。
第一排气管道洗净模式的供水量为中水量(水位6度)，因此向外筒3内供水直至比滚筒5的高度方向1/4的水平高度稍微靠上方。像这样，第一排气管道洗净模式的供水量多于滚筒洗净模式的供水量。
在第二排气管道洗净模式下，向外筒3内供给高水量(水位9度)的水，滚筒5以管道洗净转速旋转1分钟。需要说明的是，第二排气管道洗净模式的供水量不限于水位9度，只要水位为例如8～10度，第一排气管道60内的水位就会上升至能对第一排气管道60内进行漂洗的程度。此外，管道洗净转速与第一排气管道洗净模式的转速相同。像这样，第二排气管道洗净模式下的滚筒5的转速大于滚筒洗净模式下的滚筒5的转速。此外，滚筒5的旋转方向与第一排气管道洗净模式的旋转方向相同。
第二排气管道洗净模式的供水量为高水量(水位9度)，因此多于第一排气管道洗净模式的供水量，向外筒3内供水直至比滚筒5的高度方向1/2的水平高度稍微靠下方。像这样，第二排气管道洗净模式的供水量多于滚筒洗净模式的供水量，且多于第一排气管道洗净模式的供水量。
如图8所示，本实施方式的洗干一体机1具有包括微型计算机的控制单元100，洗干一体机1的动作由控制单元100来控制。控制单元100具备负责系统整体的控制的中央控制部(CPU)101，存储器102连接于中央控制部101。通过控制单元100，微型计算机执行储存于存储器102的程序，由此进行预定的运转动作，并且存储器102中暂时存储有执行上述程序时所使用的数据等。控制单元100连接有操作部80、滚筒洗净按钮81、重置按钮84、供水阀15、马达33以及排水阀18。
基于图9对排气管道洗净模式下的运转流程进行说明。图9是表示排气管 道洗净模式下的运转流程的流程图。
<步骤S1>
在步骤S1中，中央控制部101反复判定是否在门11打开的状态下对滚筒洗净按钮81长按操作了10秒。在由中央控制部101判定为在门11打开的状态下对滚筒洗净按钮81长按操作了10秒的情况下，前进至步骤S2。
<步骤S2>
在步骤S2中，中央控制部101反复判定门11是否已关闭。在由中央控制部101判定为门11已关闭的情况下，前进至步骤S3。
<步骤S3>
在步骤S3中，中央控制部101实施排气管道洗净模式的第一排气管道洗净模式下的运转。因此，在步骤S3中，中央控制部101控制供水阀15向外筒3内供给中水量(水位6度)的水，并且在供水结束后控制马达33使滚筒5以排气管道洗净转速旋转。当第一排气管道洗净模式下的运转结束时，前进至步骤S4。
<步骤S4>
在步骤S4中，中央控制部101实施排气管道洗净模式的第二排气管道洗净模式下的运转。因此，在步骤S4中，中央控制部101控制供水阀15向外筒3内供给高水量(水位9度)的水，并且在供水结束后控制马达33使滚筒5以排气管道洗净转速旋转。当第二排气管道洗净模式下的运转结束时，前进至步骤S5。
<步骤S5>
在步骤S5中，中央控制部101控制马达33使滚筒5停止，并且控制排水阀18排出外筒3内的水。
基于图10和图11对进行排气管道洗净模式下的运转时的第一排气管道60内的动作进行说明。图10和图11是表示排气管道洗净模式下的第一排气管道60内的动作的图。
如10的(a)所示，一般而言，在需要进行排气管道洗净模式的维护的情 况下，在第一排气管道60的内周面堆积有尘埃。
在该状态下，当排气管道洗净模式的第一排气管道洗净模式开始时，如图10的(b)所示，水从滚筒5喷出，水从外筒3经由流入口61流入第一排气管道60内。从设于滚筒5的背面侧的流入口61流入的水也流向正面侧。在此，水朝向第一排气管道60的正面侧的被堵塞的下端部流入第一排气管道60内，因此流入的水容易蓄于第一排气管道60内。
像这样，在第一排气管道洗净模式下，向外筒3内供水的水量较少，因此如图10的(c)所示，第一排气管道60内的水位并不高。在该状态下，通过滚筒5旋转，会在第一排气管道60内形成激烈的水流。通过该激烈的水流，从第一排气管道60的内周面除去堆积在第一排气管道60的内周面的尘埃。
在从第一排气管道60的内周面除去了尘埃的状态下，开始排气管道洗净模式的第二排气管道洗净模式。在第二排气管道洗净模式下，向外筒3内供水的水量较多，因此如图11的(a)所示，第一排气管道60内的水位变高。在该状态下，通过滚筒5旋转，会以不在第一排气管道60内形成激烈的水流的方式冲洗第一排气管道60的内周面，汇集从第一排气管道60的内周面除去的尘埃。
当排气管道洗净模式的第二排气管道洗净模式结束，滚筒5停止而滚筒5内的水排出时，如图11的(b)所示，从第一排气管道60的内周面除去的尘埃从流入口61向外筒3内或滚筒5内移动，与水一并从排水口16排出。
本实施方式的洗干一体机1具备：外筒3；大致圆筒形的滚筒5，自由旋转地配置于外筒3内；以及第一排气管道60，作为排气管道经由形成于外筒3的上部周面壁的流入口61与外筒3内连通，运转模式具备对第一排气管道60的内部进行洗净的排气管道洗净模式。
当采用这样的结构时，即使在从外筒3流入第一排气管道60的空气中所含的尘埃等蓄积于第一排气管道60的内周面的情况下，也能通过在排气管道洗净模式下进行运转来使水从外筒3流入第一排气管道60来去除蓄积在第一排气管道60的内周面的尘埃等。因此，维护性提高，通过手动作业来洗净第一排气管道60的内部的必要性降低。由此，能抑制由于尘埃等附着于第一排气管道60使得排气量降低而导致的烘干性能降低、排气风量减少所引起的故障等发生， 能减少通过手动作业对第一排气管道60内进行清扫的次数。
在本实施方式的洗干一体机1中，流入口61配置于在主视观察时相对于滚筒5的旋转轴向左方向偏心的位置，作为排气管道的第一排气管道60是配置为从正面侧朝向背面侧延伸且其一端侧与流入口61对置的中空的箱状构件，在排气管道洗净模式下，以滚筒5的上端部在外筒3的上部周面壁附近从流入口61不偏心的一侧朝向流入口61偏心的一侧移动的方式，滚筒5被旋转驱动。
当采用这样的结构时，外筒3内的水容易在流入第一排气管道60内之后蓄于第一排气管道60内。因此，在排气管道洗净模式下，能通过从外筒3流入第一排气管道60的水来去除蓄积于第一排气管道60的内周面的大范围内的尘埃等。
在本实施方式的洗干一体机1中，运转模式还具有用于对滚筒5的内部进行洗净的滚筒洗净模式，在排气管道洗净模式下，滚筒5以大于滚筒洗净模式下的转速的转速被旋转驱动，并且向外筒3内供水的水量多于滚筒洗净模式下向外筒3内供水的水量。
当采用这样的结构时，在排气管道洗净模式下，向外筒3内供水的水量多于滚筒洗净模式的水量，并且滚筒5的转速大于滚筒洗净模式下的转速，因此会有较多的水从外筒3流入第一排气管道60，能有效去除蓄积在第一排气管道60的内周面的尘埃等。
在本实施方式的洗干一体机1中，排气管道洗净模式包括：第一排气管道洗净模式，是向外筒3内供水的水量为第一水量(水位6度)的模式；以及第二排气管道洗净模式，在第一排气管道洗净模式之后实施，是向外筒3内供水的水量为多于第一水量的第二水量(水位9度)的模式。
当采用这样的结构时，在排气管道洗净模式下，首先，能在第一排气管道60内的水位低的状态下使第一排气管道60的内部产生激烈的水流从而将蓄积在第一排气管道60的内周面的尘埃等除去后，在第一排气管道60内的水位高的状态下使第一排气管道60的内部产生平缓的水流从而冲洗掉从第一排气管道60的内周面除去的尘埃等。
以上，对本发明的实施方式进行了说明，但本实施方式的结构不限定于上 述结构，能进行各种变形。
例如，虽然在上述实施方式中，对洗干一体机1中流入口61配置于在主视观察时相对于滚筒5的旋转轴向左方向偏心的位置的情况进行了说明，但不限于此。在洗干一体机1中，流入口61也可以配置于在主视观察时相对于滚筒5的旋转轴向右方向偏心的位置。
虽然在上述实施方式中，对洗干一体机1中第一排气管道60是配置为从正面侧朝向背面侧延伸且其背面侧与流入口61对置的中空的箱状构件的情况进行了说明，但不限于此。在洗干一体机1中，第一排气管道60也可以是配置为从正面侧朝向背面侧延伸且其正面侧与流入口61对置的中空的箱状构件。本发明的排气管道的结构是任意的。
虽然在上述实施方式中，对排气管道洗净模式下滚筒5绕左旋转方向被旋转驱动的情况进行了说明，但不限于此。在排气管道洗净模式下，滚筒5也可以绕右旋转方向被旋转驱动。此外，在排气管道洗净模式下，滚筒5也可以被旋转驱动为交替反复绕左旋转方向和绕右旋转方向。
虽然在上述实施方式中，排气管道洗净模式通过第一排气管道洗净模式和在第一排气管道洗净模式之后实施的第二排气管道洗净模式这两种运转来实施，但不限于此。排气管道洗净模式也可以通过一种运转来实施，还可以通过三种以上运转来实施。此外，虽然示出了与排气管道洗净模式的第一排气管道洗净模式和第二排气管道洗净模式有关的运转时间的例子，但这些运转时间是任意的。
虽然在上述实施方式中，在门11打开的状态下将滚筒洗净按钮81长按操作了10秒后，在门11关闭的情况下开始排气管道洗净模式，但不限于此。用于开始排气管道洗净模式的操作等是任意的。
在上述实施方式中，运转模式具有滚筒洗净模式，但也可以应用于运转模式不具有滚筒洗净模式的洗干一体机。
其他的结构也可以在不脱离本发明的主旨的范围内进行各种变形。
