Description

洗衣机 技术领域
本发明涉及一种例如进行清洗过程、漂洗过程以及脱水过程的洗衣机。
背景技术
现有的洗衣机中，有一种不具有烘干功能的洗衣机，其自动地进行从清洗过程到漂洗过程和脱水过程，还有一种具有烘干功能的洗衣机，其自动地进行从清洗过程到漂洗过程、脱水过程和烘干过程。
现有的洗衣机中，可以考虑向滚筒内供给臭氧，通过臭氧水来进行漂洗洗涤物的过程(所谓的除菌漂洗)。因此，在这种洗衣机中，通过臭氧产生装置产生臭氧并将该臭氧供给至滚筒内，但是供给至滚筒内的臭氧并没有全部溶入水中，因此滚筒内充满臭氧。
在通常的运转中，进行除菌漂洗之后，进行脱水过程再结束洗涤，因此在洗涤适当结束的情况下，滚筒内的臭氧浓度会变低，即使打开洗衣机的门也没有问题。
但是，当在脱水过程中洗涤物的偏倚大时，有时无法启动脱水。洗衣机中，在脱水过程中断的情况下，会在进行解开洗涤物的运转之后重新开始脱水过程，但是之后，当脱水过程被反复中断了规定次数时，会无法启动脱水，因此脱水过程中止。
这种情况下，洗衣机的显示部会显示错误，进行促使用户作出解开洗涤物的动作的处理。这时，由于洗涤没有恰当地结束，因此滚筒内的臭氧浓度不够低。因此，在洗衣机中进行了除菌漂洗的情况下，在这之后会锁定洗衣机的门使其打不开，直到滚筒内的臭氧浓度足够低。
因此，在脱水过程中止的情况下，尽管滚筒停止，但是直到滚筒内的臭氧浓度足够低为止，都不能打开洗衣机的门。因此，用户不能进行解开洗涤物的 动作，因此洗衣机的运转会长时间停止。
此外，已知臭氧在水中的溶解度根据水温而不同。例如，图16示出了氧和臭氧相对于纯水的溶解度(引用自文献：环境领域中臭氧的实际使用(医疗·环境臭氧研究会，增刊3号，2007)的表1－6)。臭氧的溶解度在水温为0℃时为1.124g/L，与此相对，在水温为25℃时为0.613g/L。因此，可知与水温为0℃的情况相比，水温为25℃的情况下臭氧不易溶于水中。
在洗衣机中为了进行除菌漂洗，滚筒内需要规定浓度的臭氧水，为了通过臭氧电极产生规定量的臭氧，对臭氧电极进行通电。在供水温度低的情况下，由于臭氧容易溶入水中，因此供给至滚筒内的臭氧水的浓度变高。与此相对，在供水温度高的情况下，由于臭氧不易溶于水中，因此供给至滚筒内的臭氧水的浓度变低。
洗衣机中，为了能应对各种供水温度，即使在供水温度高而臭氧不易溶于水时，也需要配合高的供水温度将臭氧电极的通电时间设定地较长，以便得到为了进行除菌漂洗而需要的规定浓度的臭氧水。
因此，由于现有的洗衣机无论供水温度如何，都将臭氧电极的通电时间设定为固定，因此在供水温度低的情况下，臭氧电极的通电时间被设定为超过必要时间。由此，在供水温度低的情况下，滚筒内的臭氧浓度可能会超过必要的浓度。
因此，即使洗衣机中在除菌漂洗后滚筒内的臭氧浓度高时，也需要将锁门时间设定得长，以便不解除门的锁定直到滚筒内的臭氧浓度足够低为止。由于现有洗衣机无论供水温度如何，都将锁门时间设定为固定，因此锁门时间被设定得较长，从而存在洗衣机的运转效率降低的问题。

具体实施方式
以下，参照附图对本发明的实施方式的洗衣机进行说明。
(第一实施方式)
如图1所示，洗衣机1为滚筒式洗衣机，具备构成外观的箱体即洗衣机主体10。洗衣机主体10的前表面10a从中央部倾斜至上部，在倾斜的面上形成有洗涤物的投入口11。投入口11由自由开闭的门12覆盖。
在洗衣机主体10内，外筒20由多个减振器21弹性支承。在外筒20内，自由旋转地配置有滚筒22。外筒20和滚筒22以后表面侧变低的方式相对于水平方向倾斜。由此，滚筒22绕沿相对于水平方向倾斜的方向延伸的旋转轴旋转。
外筒20的前表面的开口部20a和滚筒22的前表面的开口部22a与投入口11对置，与投入口11一起由门12关闭。在滚筒22的周壁形成有许多脱水孔22b。进一步地，在滚筒22的周壁，沿周向以大致相等的间隔设置有三个提升筋23。
在滚筒22的后部，自由旋转地配置有旋转翼24。旋转翼24具有大致圆盘形状。在旋转翼24的表面，形成有从中央部向径向外侧延伸的多个突状部24a。旋转翼24与滚筒22同轴进行旋转。
在外筒20的后方，配置有产生驱动滚筒22和旋转翼24的转矩的马达30。
如图2所示，洗衣机1具备：用于向外筒20内的滚筒22进行普通供水的供水路51、从供水路51分支的臭氧供水路52、用于向外筒20内进行热水的供给的热水供给路53、用于排出外筒20内的水的排水路54以及用于向外筒20内供给柔顺剂、洗涤剂的柔顺剂供给路55和洗涤剂供给路56。在热水供给路53连接有热水供给器53A，被供给为热水供给器53A设定的热水供给设定温度的热水。
供水路51、热水供给路53、柔顺剂供给路55和洗涤剂供给路56与设置于外筒20的上方的集水导入部57连接，臭氧供水路52与外筒20的上方连接，排水路54与外筒20的下方连接。在外筒20的上端附近，设置有用于将超过水位上限的水排出的溢流通路58。
洗衣机1能实施清洗过程、漂洗过程、除菌漂洗过程、热水供给漂洗过程、脱水过程等。因此，洗衣机1中，通过适当地开闭作为各个给排系统的阀的供水阀51a、臭氧供水阀52a、热水供给阀53a、排水阀54a，进行普通供水、臭氧水供给、热水供给、排水。在供水阀51a和热水供给阀53a的上游分别配置有供水粗滤器51b、53b。
在外筒20的上端附近连接有排气路60，滚筒22内的空气、臭氧通过排气路60向机外排出。在排气路60配置有活性炭60a，经过排气路60的气体在经 过活性炭60a之后向机外排出，由此，经过排气路60的臭氧的一部分被活性炭60a消耗。
洗衣机1能进行向滚筒22供给臭氧水并通过臭氧水来漂洗洗涤物的过程(所谓的除菌漂洗)。因此，在用于向滚筒22的内部供给臭氧水的臭氧供水路52配置有产生臭氧的臭氧产生装置61。
如图3所示，臭氧产生装置61包括臭氧电极63，臭氧电极63配置于大致水平地设置于臭氧供水路52的一部分的臭氧产生区域62。本实施方式中，配置有三根臭氧电极63a、63b、63c来作为臭氧电极63。臭氧产生装置61中，使三根臭氧电极63a、63b、63c串联穿过，通过水的电解而产生臭氧。
在臭氧供水路61的臭氧产生区域62，于上游侧形成有向上延伸的第一连接部62a，于下游侧形成有向下延伸的第二连接部62b。因此，通过对臭氧电极63进行通电，使得与臭氧电极63的表面接触的水被分解而产生臭氧气体，该臭氧气体溶解在水中而成为臭氧水。
图4是本实施方式的洗衣机1的控制框图。如图4所示，洗衣机1的控制部80例如由微型计算机等构成，具备CPU、储存有控制洗衣机1的动作的程序的ROM以及暂时存储执行上述程序时所用的数据等的RAM。洗衣机1的运转动作由该控制部80控制。
控制部80具有锁门时间确定部80a、缩短速度确定部80b以及热水供给温度存储单元80c。此外，控制部80连接有操作部81、马达30、供水阀51a、排水阀54a、臭氧供水阀52a、臭氧产生装置61以及锁门装置82。
锁门时间确定部80a确定除菌漂洗过程之后将门12维持在锁定状态的锁门时间。因此，锁门时间确定部80a考虑除菌漂洗过程之后直到滚筒22内的臭氧浓度充分降低至规定浓度以下为止的消臭氧时间来确定锁门时间。
由此，根据由锁门时间确定部80a确定的锁门时间控制锁门装置82，使得直到滚筒22内的臭氧浓度降低至规定浓度以下为止，打不开门12。
除菌漂洗过程中，进行供水直到臭氧水达到滚筒22内的臭氧漂洗设定水位之后，进行供水直到普通水达到滚筒22内的规定水位。在为了进行除菌漂洗而进行供水直到普通水达到滚筒22内的规定水位的状态下，滚筒22内需要规定 浓度以上的臭氧水。
因此，进行供水直到臭氧水达到滚筒22内的臭氧漂洗设定水位的臭氧水的浓度需要为如下的浓度：在进行供水直到普通水达到滚筒22内的规定水位之后，滚筒22内的臭氧水的浓度达到规定浓度以上。
如上所述，在供水温度低的情况下，由于臭氧容易溶入水中，因此供给至滚筒22内的臭氧水的浓度变高。与此相对，在供水温度高的情况下，由于臭氧不易溶于水中，因此供给至滚筒22内的臭氧水的浓度低。
因此，即使在除菌漂洗后滚筒内的臭氧浓度高时，为了充分降低滚筒内的臭氧浓度，考虑到供水温度低的情况，无论供水温度如何，锁门时间确定部80b都确定为固定的锁门时间T0。因此，由锁门时间确定部80a确定的锁门时间T0在供水温度高的情况下会超过必要的时间。
缩短速度确定部80b在进行热水供给漂洗过程之后，根据热水供给漂洗过程中的滚筒22内的水温，确定作为缩短锁门时间的速度的缩短速度。使用存储于热水供给温度存储单元80c的热水供给器53A的热水供给设定温度作为热水供给漂洗过程中的滚筒22内的水温。需要说明的是，无论除菌漂洗过程的供水温度如何，缩短速度确定部80b都将除菌漂洗过程之后直到进行热水供给漂洗过程的缩短速度确定为固定的缩短速度ΔT 0。
洗衣机1中，在除菌漂洗过程之后，在向滚筒22供给了热水的状态下进行热水供给漂洗过程。当滚筒22内的水温高时，会促进臭氧分解，加快滚筒22内的臭氧浓度的降低。
因此，在进行了热水供给漂洗过程的情况下，直到经过由锁门时间确定部80a确定的锁门时间，滚筒22内的臭氧浓度变为规定浓度以下。
因此，缩短速度确定部80b根据热水供给漂洗过程中的滚筒22内的水温来确定缩短速度，使得与进行热水供给漂洗相应的的锁门时间快速达到0。缩短速度是每一定时间分解臭氧的速度。使用存储于热水供给温度存储部80c的热水供给设定温度作为热水供给漂洗过程中的滚筒22内的水温。
具体而言，如图5所示，缩短速度确定部80b在热水供给漂洗过程中的漂洗水温T S低于T S1℃的情况下，将缩短速度确定为ΔT 1，在漂洗水温T S为T S1℃ 以上且低于T S2℃的情况下，将缩短速度确定为ΔT 2，在漂洗水温T S为T S2℃以上的情况下，将缩短速度确定为ΔT 3。图5中，T S1＜T S2，0＜ΔT 1＜ΔT 2＜ΔT 3。因此，缩短速度越快，规定的锁门时间变为0所需的时间越短。
例如，在由锁门时间确定部80a确定的锁门时间为T，由缩短速度确定部80b确定的缩短速度为ΔT的情况下，如图6所示，每当锁门时间T经过一定时间t则缩短速度ΔT就会缩短。因此，当锁门时间T－n×ΔT(其中，n为整数)达到0时，滚筒22内的臭氧浓度变为规定浓度以下。
热水供给温度存储单元80c存储连接有热水供给路53的热水供给器53A的热水供给设定温度。
操作部81包括用于进行除菌漂洗的除菌漂洗按钮81a。操作部81将与用户所操作的按钮对应的输入信号输出至控制部80。
控制部80通过控制马达30来控制滚筒22的转速。
控制部80通过控制供水阀51a和排水阀54a来进行向外筒20内的供水和从外筒20内的排水。
控制部80通过控制臭氧供水阀52a和臭氧产生装置61，在进行除菌漂洗时从臭氧供水路52向滚筒22内供给臭氧水。
控制部80通过控制将门12切换为锁定状态或解锁状态的锁门装置82，从而进行门12的锁定和解锁。
接着，基于图7对洗衣机1的运转动作进行说明。洗衣机1例如具有清洗过程、漂洗过程、除菌漂洗过程、热水供给漂洗过程以及脱水过程，并且能进行不具有烘干过程的洗涤模式的运转。需要说明的是，本实施方式中，对如下情况进行说明：在清洗过程结束之前，用户按下操作部81的除菌漂洗按钮81a，投入规定的金额，从而进行使用了臭氧水的除菌漂洗过程。
＜步骤S1：清洗过程＞
步骤S1中，首先，使用者打开门12，向滚筒22内放入洗涤物，关闭门12。当清洗过程开始时，控制部80打开用于供给普通洗涤水的供水阀51a，向滚筒22供给普通水。此时，控制部80关闭排水阀54a，供给来的水蓄于外筒20和 滚筒22内。然后，当供给了规定量的水时，控制部80关闭供水阀51a，驱动(接通)马达30而使滚筒22旋转。
然后，当规定时间的清洗动作结束时，控制部80打开排水阀54a，滚筒22内的清洗水经由排水路54向机体外部排出。排水后，控制部80通过马达30使滚筒22高速旋转，进行将洗涤物中所含的洗涤水脱去的中间脱水。通过中间脱水而从洗涤物中脱去的洗涤水排出至滚筒22内，经由排水路54向机体外部排出。
＜步骤S2：漂洗过程＞
当步骤S1中的清洗过程结束时，在步骤S2中进行漂洗过程。当漂洗过程开始时，控制部80关闭排水阀54a，打开用于供给普通洗涤水的供水阀51a，向滚筒22供给规定量的漂洗水。然后，当供给了规定量的水时，控制部80关闭供水阀51a，通过马达30使滚筒22旋转，进行规定时间的滚筒22内的洗涤物的漂洗。
当漂洗结束时，控制部80打开排水阀54a，将滚筒22内的漂洗水经由排水路54向机体外部排出。排水后，通过与上述相同的脱水动作进行中间脱水，脱去洗涤物中所含的漂洗水。该脱去的漂洗水也如上所述，经由排水路54向机体外部排出。
＜步骤S3：除菌漂洗过程＞
当步骤S2中的漂洗过程结束时，在步骤S3中进行除菌漂洗过程。当除菌漂洗过程开始时，控制部80关闭排水阀54a，打开臭氧供水阀52a，经由臭氧供水路52向滚筒22供给臭氧水。然后，控制部80关闭臭氧供水阀52a，停止供给臭氧水，打开用于供给普通水的供水阀51a，将普通水作为漂洗水向滚筒22供给。
然后，当供给漂洗水时，控制部80通过马达30使滚筒22旋转，使用臭氧水进行规定时间的滚筒22内的洗涤物的除菌漂洗。当除菌漂洗结束时，控制部80打开排水阀54a，将滚筒22内的漂洗水经由排水路54向机体外部排出。
＜步骤S4：热水供给漂洗过程＞
当步骤S3中的除菌漂洗过程结束时，在步骤S4中进行热水供给漂洗过程。 当热水供给漂洗过程开始时，控制部80关闭排水阀54a，打开热水供给阀53a，经由热水供给路53向滚筒22供给热水。需要说明的是，在开始供给热水时滚筒22内有水的情况下，控制部80打开排水阀54a，将滚筒22内的水排出之后，打开热水供给阀53a，经由热水供给路53向滚筒22供给热水。因此，能防止滚筒22内水温低的水与供给的热水混合。
然后，当热水供给结束时，控制部80通过马达30使滚筒22旋转，通过供给热水对滚筒22内的洗涤物进行规定时间的热水供给漂洗。当热水供给漂洗结束时，控制部80打开排水阀54a，将滚筒22内的漂洗水经由排水路54向机体外部排出。
＜步骤S5：脱水过程＞
当步骤S4中的热水供给漂洗过程结束时，在步骤S5中进行脱水过程。当脱水过程开始时，控制部80使滚筒22的转速向目标转速上升，当达到目标转速时，进行脱水运转直到经过规定脱水时间。当脱水过程结束时，控制部80将滚筒22的旋转停止，结束洗涤模式的动作。在脱水过程中脱去的水也如上所述经由排水路54向机体外部排出。
基于图8对本实施方式中的确定锁门时间的缩短速度的流程进行说明。
＜步骤S101＞
当步骤S101中的热水供给漂洗过程开始时，控制部80打开热水供给阀53a，经由热水供给路53向滚筒22供给热水。
＜步骤S102＞
在步骤S102中，控制部80继续向滚筒22供给热水直到滚筒22内的漂洗水位达到热水供给漂洗设定水位。
＜步骤S103＞
当滚筒22内的漂洗水位达到热水供给漂洗设定水位时，在步骤S103中，控制部80停止热水供给。
＜步骤S104＞
步骤S104中，控制部80判定存储于热水供给温度存储部80a的热水供给 设定温度是否低于T n1℃。
＜步骤S105＞
在步骤S104中控制部80判定热水供给设定温度低于T n1℃的情况下，在步骤S105中，控制部80将缩短速度确定为ΔT1，结束处理。
＜步骤S106＞
在步骤S104中控制部80判定热水供给设定温度为T n1℃以上的情况下，进入步骤S106，控制部80判定热水供给设定温度是否低于T n2℃。
＜步骤S107＞
在步骤S106中控制部80判定热水供给设定温度低于T n2℃的情况下，在步骤S107中，控制部80将缩短速度确定为ΔT 2，结束处理。
＜步骤S108＞
在步骤S106中控制部80判定热水供给设定温度为T n2℃以上的情况下，进入步骤S108，控制部80将缩短速度确定为ΔT 3，结束处理。
本实施方式的洗衣机1具备：供水路51，用于向配置于洗衣机主体10内的滚筒22进行普通供水；臭氧供水路52，用于向滚筒22进行臭氧水的供给；臭氧电极63，使臭氧供水路52内产生臭氧；热水供给路53，用于向滚筒22供给热水；以及作为控制单元的控制部80，对将可开闭地设置于洗衣机主体10的门12切换为锁定状态或解锁状态的锁门装置82进行控制，在进行除菌漂洗过程之后，在从热水供给路53向滚筒22供给了热水的状态下实施热水供给漂洗过程，其中，除菌漂洗过程是在从臭氧供水路52向滚筒22内供给了臭氧水的状态下进行漂洗的过程。
由此，本实施方式的洗衣机1中，在进行除菌漂洗过程之后，在向滚筒22供给了热水的状态下实施热水供给漂洗过程，由此能促进臭氧在滚筒22内分解，缩短滚筒22内的臭氧浓度充分降低所需的时间。因此，能缩短门12被锁定的锁门时间。此外，能延长活性炭60a和止水密封件的使用期限。
本实施方式的洗衣机1具备：作为锁门时间确定单元的锁门时间确定部80a，确定在进行除菌漂洗过程之后将门12维持在锁定状态的锁门时间；以及作为缩 短速度确定单元的缩短速度确定部80b，根据热水供给漂洗过程中的滚筒22内的水温，确定锁门时间的缩短速度，缩短速度确定部80b以热水供给漂洗过程中的滚筒22内的水温越高则缩短速度越快的方式来确定缩短速度。
由此，本实施方式的洗衣机1中，根据热水供给漂洗过程中的滚筒22内的水温，确定与滚筒22内的水温对应的锁门时间的缩短速度。因此，能适当地缩短锁门时间来进行门12的解锁。
(第二实施方式)
基于图9～图15对本发明的第二实施方式的洗衣机进行说明。
本实施方式的洗衣机与第一实施方式的洗衣机1主要的不同点在于，相对于第一实施方式中确定固定的锁门时间，本实施方式中，确定与供水温度对应的锁门时间，相对于第一实施方式中确定与热水供给漂洗过程中的水温对应的缩短速度，本实施方式中，在确定与热水供给漂洗过程中的水温对应的缩短速度之后，根据热水供给漂洗过程中的滚筒内的漂洗水位和漂洗时间来校正该缩短速度。此外，本实施方式的洗衣机具备检测滚筒22内的水温的水温检测传感器85。对于本实施方式的洗衣机的结构中与第一实施方式的洗衣机1相同的结构省略说明。
如图9所示，控制部180具有锁门时间确定部180a和缩短速度确定部180b。缩短速度确定部180b包括校正部180c。此外，在控制部180连接有操作部81、马达30、供水阀51a、排水阀54a、臭氧供水阀52a、臭氧产生装置61、锁门装置82以及检测滚筒22内的水的温度的水温检测传感器85。
锁门时间确定部180a根据除菌漂洗过程中的供水温度，确定在除菌漂洗过程之后将门12维持于锁定状态的锁门时间。作为供水温度，使用在臭氧水的供给结束而臭氧电极63的通电停止时由水温检测传感器85检测出的滚筒22内的水温。
具体而言，如图10所示，在供水温度T p低于T p1℃的情况下，锁门时间确定部180a将锁门时间确定为T 1，在供水温度T p为T p1℃以上且低于T p2℃的情况下，将锁门时间确定为T 2，在供水温度T p为T p2℃以上的情况下，将锁门时间确定为T 3。图10中，T p1＜T p2，T 1＞T 2＞T 3。
即，在供水温度低的情况下，由于臭氧容易溶入水中，因此供给至滚筒22内的臭氧水的浓度高，因此锁门时间确定部180a将锁门时间确定为较长的时间。与此相对，在供水温度高的情况下，由于臭氧不易溶于水中，因此供给至滚筒22内的臭氧水的浓度低，因此锁门时间确定部180a将锁门时间确定为较短的时间。
(1)缩短速度确定部180b根据除菌漂洗过程中的供水温度，确定在除菌漂洗过程之后缩短锁门时间的速度即第一缩短速度。作为供水温度，使用在臭氧水的供给结束而臭氧电极63的通电停止时，由水温检测传感器85检测出的滚筒22内的水温。
具体而言，如图10所示，在供水温度T p低于T p1℃的情况下，缩短速度确定部80b将缩短速度确定为ΔT 1’，在供水温度T p为T p1℃以上且低于T p2℃的情况下，将缩短速度确定为ΔT 2’，在供水温度T p为T p2℃以上的情况下，将缩短速度确定为ΔT 3’。图10中，T p1＜T p2，0＜ΔT 1’＜ΔT 2’＜ΔT 3’。因此，缩短速度越快，锁门时间变为0所需的时间越短。
(2)缩短速度确定部180b根据与热水供给漂洗过程中的滚筒22内的水温对应的缩短速度，确定作为缩短锁门时间的速度的第二缩短速度。作为热水供给漂洗过程中的滚筒22内的水温，使用热水供给漂洗过程中由水温检测传感器85检测出的滚筒22内的水温。
具体而言，与第一实施方式相同，如图5所示，在热水供给漂洗过程中的漂洗水温T S低于T S1℃的情况下，缩短速度确定部180b将缩短速度确定为ΔT 1，在漂洗水温T S为T S1℃以上且低于T S2℃的情况下，将缩短速度确定为ΔT 2，在漂洗水温T S为T S2℃以上的情况下，将缩短速度确定为ΔT 3。图5中，T S1＜T S2，ΔT 1＜ΔT 2＜ΔT 3。因此，缩短速度越快，规定的锁门时间变为0所需的时间越短。
因此，在进行除菌漂洗过程之后直到进行热水供给漂洗过程，缩短速度确定部180b将缩短锁门时间的缩短速度确定为第一缩短速度。由此，在进行除菌漂洗过程之后直到进行热水供给漂洗过程，根据第一缩短速度来缩短锁门时间。
在进行热水供给漂洗过程之后，缩短速度确定部180b将缩短锁门时间的缩 短速度确定为第二缩短速度。由此，在进行热水供给漂洗过程之后，根据第二缩短速度来缩短锁门时间。
因此，洗衣机1中，在进行热水供给漂洗过程之后，进行除菌漂洗过程之后直到进行热水供给漂洗过程而确定的第一缩短速度被重新设定为第二缩短速度。
校正部180c根据热水供给漂洗过程中的滚筒22内的漂洗水位和漂洗时间进行校正。热水供给漂洗过程中的滚筒22内的漂洗水位在洗衣机中被预先设定。
具体而言，如图11所示，在漂洗水位H t低于H 1的情况下，校正部180c将缩短速度校正值确定为ΔT h1，在漂洗水位H t为H 1以上且低于H 2的情况下，将缩短速度校正值确定为ΔT h2，在漂洗水位H t为H 2以上的情况下，将缩短速度校正值确定为ΔT h3。图11中，H t＜H 2，0＜ΔT h1＜ΔT h2＜ΔT h3。
因此，校正部180c以使由缩短速度确定部180b确定的缩短速度与缩短速度校正值相应地增加的方式进行校正。由此，以漂洗水位越高则缩短速度越快的方式校正缩短速度。这是因为，在热水供给漂洗过程中，漂洗水位越高，则滚筒22内的水越被搅拌，滚筒22内的臭氧越容易与搅拌的水碰撞而被消耗。
此外，如图12所示，在漂洗时间T t低于T t1的情况下，校正部180c将缩短速度校正值确定为ΔT t1，在漂洗水温T t为T t1以上且低于T t2的情况下，将缩短速度校正值确定为ΔT t2，在漂洗水温T t为T t2以上的情况下，将缩短速度校正值确定为ΔT t3。图12中，T t1＜T t2，0＜ΔT t1＜ΔT t2＜ΔT t3。
因此，校正部180c以使由缩短速度确定部180b确定的缩短速度与缩短速度校正值相应地增加的方式进行校正。由此，以漂洗时间越长则缩短速度越快的方式校正缩短速度。这是因为，在热水供给漂洗过程中，则漂洗时间越长，滚筒22内的臭氧越容易与搅拌的水碰撞而被消耗。
本实施方式中，基于图13，对确定锁门时间和缩短速度的流程进行说明。
＜步骤S201＞
在步骤S201中，当除菌漂洗过程开始时，控制部80打开臭氧供水阀52a并且开始臭氧电极63的通电，开始经由臭氧供水路52向滚筒22供给臭氧水。
＜步骤S202＞
在步骤S202中，控制部80继续向滚筒22供给臭氧水直到滚筒22内的水位达到臭氧漂洗设定水位。
＜步骤S203＞
当滚筒22内的水位达到臭氧漂洗设定水位时，在步骤S203中，控制部80关闭臭氧供水阀52a并且停止臭氧电极63的通电，停止臭氧水的供给。
＜步骤S204＞
在步骤S204中，控制部80通过水温检测传感器85检测滚筒22内的水温作为供水温度。因此，控制部80检测与供给至配置于臭氧供水路52的臭氧电极63的水的温度大致相同温度的供水温度T p。
＜步骤S205＞
在步骤S205中，控制部80判定供水温度是否低于T p1℃。
＜步骤S206＞
在步骤S205中控制部80判定供水温度低于T p1℃的情况下，在步骤S206中，控制部80将锁门时间确定为T 1并且将缩短速度确定为ΔT 1’，结束处理。
＜步骤S207＞
在步骤S205中控制部80判定供水温度为T p1℃以上的情况下，进入步骤S207，控制部80判定供水温度是否低于T p2℃。
＜步骤S208＞
在步骤S207中控制部80判定供水温度低于T p2℃的情况下，在步骤S208中，控制部80将锁门时间确定为T 2并且将缩短速度确定为ΔT 2’，结束处理。
＜步骤S209＞
在步骤S207中控制部80判定供水温度为T p2℃以上的情况下，进入步骤S209，控制部80将锁门时间确定为T 3并且将缩短速度确定为ΔT 3’，结束处理。
本实施方式中，基于图14，对确定锁门时间的缩短速度的流程进行说明。
＜步骤S301＞
当步骤S301中的热水供给漂洗过程开始时，控制部80打开热水供给阀53a，经由热水供给路53向滚筒22供给热水。
＜步骤S302＞
在步骤S302中，控制部80继续向滚筒22供给热水直到滚筒22内的漂洗水位达到设定水位。
＜步骤S303＞
当滚筒22内的漂洗水位达到设定水位时，在步骤S303中，控制部80关闭热水供给阀53a，停止供给热水。
＜步骤S304＞
在步骤S304中，控制部80通过水温检测传感器85检测滚筒22内的水温作为热水供给漂洗过程中的漂洗水温。因此，控制部80检测向滚筒22内供给热水之后的漂洗水温T s。
＜步骤S305＞

本实施方式的洗衣机具备：供水路51，用于向配置于洗衣机主体10内的滚筒22进行普通供水；臭氧供水路52，用于向滚筒22进行臭氧水的供水；臭氧电极61，使臭氧供水路52内产生臭氧；热水供给路53，用于向滚筒22供给热水；水温检测传感器85，检测滚筒22内的水温；作为控制单元的控制部80，对将可开闭地设置于洗衣机主体10的门12切换为锁定状态或解锁状态的锁门装置82进行控制；作为锁门时间确定单元的锁门时间确定部80a，根据在从臭氧供水路52向滚筒22内供给了臭氧水的状态下进行漂洗的除菌漂洗过程中的滚筒22内的水温，确定将门12维持在锁定状态的锁门时间；作为第一缩短速度确定单元的缩短速度确定部80b，根据除菌漂洗过程中的滚筒22内的水温，确定锁门时间的第一缩短速度；以及作为第二缩短速度确定单元的缩短速度确定部80b，根据在进行除菌漂洗过程之后在从热水供给路53向滚筒22供给了热水的状态下实施的热水供给漂洗过程中的滚筒22内的水温，确定锁门时间的第二缩短速度，在进行除菌漂洗过程之后直到进行热水供给漂洗过程，根据第一缩短速度来缩短锁门时间，在进行热水供给漂洗过程之后，根据第二缩短速度 来缩短锁门时间。
本实施方式的洗衣机中，在进行除菌漂洗过程之后直到进行热水供给漂洗过程，根据基于除菌漂洗过程中的滚筒22内的水温而确定的第一缩短速度来缩短锁门时间，在进行热水供给漂洗过程之后，根据基于热水供给漂洗过程中的滚筒22内的水温而确定的第二缩短速度来缩短锁门时间。因此，在进行除菌漂洗过程之后进行热水供给漂洗过程的情况下，能根据热水供给漂洗过程中的滚筒22内的水温，重新设定锁门时间的缩短速度。因此，能适当地缩短锁门时间来进行门的解锁。
本实施方式的洗衣机具备：作为缩短速度校正单元的校正部80c，以热水供给漂洗过程中的滚筒22内的水位越高则缩短速度越快的方式校正缩短速度。

由此，本实施方式的洗衣机中，能根据热水供给漂洗过程中的漂洗时间，适当地校正锁门时间的缩短速度。
(第三实施方式)
基于图15对本发明的第三实施方式的洗衣机进行说明。
本实施方式的洗衣机与第一实施方式的洗衣机1主要的不同点在于，本实施方式中，在进行除菌漂洗过程之后中止了脱水过程的情况下，从热水供给路53向滚筒22供给热水。对于本实施方式的洗衣机的结构中与第一实施方式的洗衣机1相同的结构省略说明。
如图15所示，控制部280具有锁门时间确定部80a、缩短速度确定部80b、热水供给温度存储单元80c以及偏心检测部280d。此外，控制部280连接有操作部81、马达30、供水阀51a、排水阀54a、臭氧供水阀52a、臭氧产生装置61、锁门装置82以及振动开关31。
本实施方式中，在外筒20装配有通过振动而接通/断开的振动开关31，该 振动因滚筒22的旋转而产生。
偏心检测部280d根据来自振动开关31的检测信号，在脱水过程中滚筒22进行旋转时，检测滚筒22内的洗涤物的偏倚(偏心)。具体而言，在振动开关31的接通、断开信号中接通时间的间隔比规定时间长的情况下，偏心检测部280d将滚筒22的振动视为异常振动，检测出滚筒22内的洗涤物的偏倚为规定的偏倚以上。即，在洗涤物未均匀地贴附于滚筒22的周壁而产生规定量以上的偏倚的情况下，偏心检测部280d检测出滚筒22内的洗涤物的偏倚为规定的偏倚以上。本实施方式的洗衣机中，在滚筒22内的洗涤物的偏倚为规定的偏倚以上的情况下，脱水过程中断，进行解开运转，但是当脱水过程的中断反复了两次以上的规定次数时，中止脱水过程。
本实施方式的洗衣机能取得与第一实施方式的洗衣机1相同的效果。
本实施方式的洗衣机具备：供水路51，用于向配置于洗衣机主体10内的滚筒22进行普通供水；臭氧供水路52，用于向滚筒22进行臭氧水的供给；臭氧电极63，使臭氧供水路52内产生臭氧；热水供给路53，用于向滚筒22供给热水；以及作为偏心检测单元的偏心检测部280d，检测滚筒22内的洗涤物的偏倚，所述洗衣机在进行除菌漂洗过程之后，进行脱水过程，在因脱水过程中由偏心检测部280d检测出的洗涤物的偏倚为规定的偏倚以上而中止了脱水过程的情况下，从热水供给路53向滚筒22供给热水，其中，除菌漂洗过程是在从臭氧供水路52向滚筒22内供给了臭氧水的状态下进行漂洗的过程。
由此，本实施方式的洗衣机中，在因洗涤物的偏倚大而中止了脱水过程的情况下，能通过向滚筒22供给热水，促进臭氧在滚筒22内分解，缩短滚筒22内的臭氧浓度充分降低所需的时间。
以上，对本发明的实施方式进行了说明，但是各部分的具体结构不只局限于上述的实施方式。
上述第一～第三实施方式中，滚筒22绕相对于水平方向沿倾斜方向延伸的旋转轴进行旋转，但滚筒22也可以绕沿水平方向延伸的旋转轴进行旋转。此外，本发明能适用于具有绕沿垂直方向延伸的旋转轴进行旋转的滚筒的洗衣机。
上述第二实施方式中，以由检测滚筒22内的水温的水温检测传感器85检 测出的水温来作为进行除菌漂洗过程时供给至臭氧电极63的水的温度即供水温度，但是也可以是如下情况：例如，集中导入部57中具备检测供给至滚筒22内的水的温度的供水温度传感器，以由该供水温度传感器检测出的水温来作为进行除菌漂洗过程时供给至臭氧电极63的水的温度即供水温度。此外，臭氧供水路52中也可以具备检测供给至臭氧电极63的水的温度的供水温度传感器。
上述实施方式中，虽然分三个阶段切换图5的缩短速度、图10的锁门时间、图11的缩短速度校正值、图12的缩短速度校正值，但是切换的阶段数不局限于此。
上述实施方式中，对不具有烘干功能的洗衣机1进行了说明，但是本发明也能适用于具有烘干功能的洗衣机。
