技术领域
本申请涉及衣物处理洗衣机技术领域，尤其涉及一种洗衣机及其控制方法。
背景技术
随着生活节奏的加快，毛衣、棉衣这些大件衣物晾晒问题让不少人犯难，湿漉漉的衣物在低温天气久晾不干，为了解决衣物久晾不干的问题，具有干衣功能的洗衣机应运而生，具有干衣功能的洗衣机的出现让衣物久凉不干不再是烦恼。
现有的具有干衣功能的洗衣机工作原理是空气经过加热器被加热后，热空气加热衣服，变成湿热空气直接排出洗衣机外部或通过冷凝系统，将湿气凝固成水之后排出，形成循环，不断地将衣服的湿气排走，达到烘干衣服的目的。然而，上述具有干衣功能的洗衣机能够对洗涤后的衣物进行烘干，不具备衣物去皱的功能，影响了用户的使用体验。
发明内容
本申请的实施例提供的洗衣机及其控制方法，用于解决现有的具有干衣功能的洗衣机不能衣物除皱的问题。
为达到上述目的，第一方面，本申请的实施例提供的洗衣机，包括：箱体；设置于所述箱体中的干衣筒，所述干衣筒的前端具有衣物投放口，后端开设有与所述干衣筒的筒腔连通的连接口；风机；送风道，所述送风道的入口与所述 风机的出风口连通，出口位于所述干衣筒的前端，且与所述衣物投放口连通；加热件，所述加热件设置于所述送风道中；除湿装置，所述除湿装置的进气口与所述连接口连通，出气口通过吸风道与所述风机的吸风口连通；喷水装置，所述喷水装置用于向所述吸风道中喷水。
第二方面，本申请的实施例提供了一种用于第一方面中所述的具有干衣功能的洗衣机的控制方法，包括以下步骤：控制加热件进入发热状态，以使温度传感器所检测的温度值位于预设温度范围内；控制风机、喷水装置以预设方式工作，以使所述具有干衣功能的洗衣机进入蒸汽洗涤模式；当进入所述蒸汽洗涤模式的时间t满足第一预设条件时，控制所述喷水装置处于停止工作状态，并控制所述风机以第一预设转速r1运行，以使所述具有干衣功能的洗衣机进入烘干模式。
本申请的实施例提供的具有干衣功能的洗衣机及其控制方法，通过增设喷水装置，这样，该具有干衣功能的洗衣机在工作时，喷水装置喷至吸风道中的水被风机吸入，并分散成小液滴，小液滴在送风道中与加热件接触并生成高温水蒸汽，高温水蒸气被送入干衣筒对衣物蒸汽洗涤，通过对衣物的蒸汽洗涤就可以对衣物进行除皱处理，提升了用户的使用体验；同时，该洗衣机工作时蒸汽的产生是在现有的烘干系统中增加喷水装置实现的，结构较简单，无需增设蒸汽发生装置，从而有利于降低该洗衣机的设计和制造成本。

第一方面，本申请实施例提供了具有干衣功能的洗衣机，如图1和图2所示，包括：箱体1；设置于箱体1中的干衣筒2，干衣筒2的前端具有衣物投放口21，后端开设有与干衣筒2的筒腔连通的连接口22；风机3；送风道4，送风道4的入口A与风机3的出风口连通，出口B位于干衣筒2的前端，且与衣物投放口21连通；加热件5，加热件5设置于送风道4中；除湿装置6，除湿装置6的进气口61与连接口22连通，出气口62通过吸风道7与风机3的吸风口连通；喷水装置8，喷水装置8用于向吸风道7中喷水。
其中，除湿装置6可以为冷凝器，冷凝器中设有连接于进气口61与出气口62之间的冷凝风道，冷凝风道内设有冷凝水通道，冷凝水通道与进水系统连通，当湿热风由进气口61进入冷凝风道内时，与冷凝水通道中的水发生热交换，湿热风中的水分冷凝，从而达到除去湿热风中水分的作用，除去水分的风由出气口62排出；喷水装置8可以设置成以下结构：如图2所示，喷水装置8包括喷头81，该喷头81设置于吸风道7中，且与进水阀82通过管路连通。喷水装置8工作时，进水阀82开启，水由进水阀82、管路进入喷头81中，并喷至吸风道7中。
如图2所示，上述具有干衣功能的洗衣机在工作时，风机3、加热件5开启，喷水装置8开启，并向吸风道7中喷水，在风机3吸力的作用下水沿吸风道7进入风机3，然后被风机3旋转的叶片31打散成小液滴，小液滴随风进入 至送风道4，然后小液滴与温度较高的加热件5接触，并汽化成高温蒸汽，接着高温蒸汽由衣物投放口21进入到干衣筒2内，对干衣筒2内的衣物进行蒸汽洗涤；
当蒸汽洗涤达到预设时间后，关闭喷水装置8，以进入烘干模式，在烘干模式下，如图1所示，从风机3的出风口吹出的风进入送风道4，经加热件5的加热后变成热风，热风经衣物投放口21进入到干衣筒2中，带走衣物上的水分，以对衣物进行烘干，带走衣物水分的热风变成饱含水蒸汽的湿热风，湿热风由连接口22进入除湿装置6进行除湿处理变成干燥的风，最终干燥的风经吸风道7进入风机3以完成一个风循环。风机3吹出的风不断在送风道4、干衣筒2、除湿装置6、吸风道7之间循环直至将干衣筒2中的衣物烘干为止。
本申请实施例提供的具有干衣功能的洗衣机，如图2所示，通过增设喷水装置8，这样，该具有干衣功能的洗衣机在工作时，喷水装置8喷至吸风道7中的水被风机3吸入，并分散成小液滴，小液滴在送风道4中与加热件5接触并生成高温水蒸汽，高温水蒸气被送入干衣筒2对衣物蒸汽洗涤，通过对衣物的蒸汽洗涤就可以对衣物进行除皱处理，提升了用户的使用体验；同时，该洗衣机工作时蒸汽的产生是在现有的烘干系统中增加喷水装置8实现的，结构较简单，无需增设蒸汽发生装置，从而有利于降低该洗衣机的设计和制造成本。
为了防止在烘干模式下送风道4输入至干衣筒2中的风的温度过高，如图2所示，该具有干衣功能的洗衣机还包括温度传感器9，温度传感器9设置于送风道4中，且位于加热件5靠近送风道4的出口的一侧。这样温度传感器9就可以对送风道4内经过加热件5的风进行温度检测，当风的温度超过预设温度范围的上限值时，加热件5停止工作，从而可以避免风的温度过高，进而可以防 止过热的风进入到干衣筒2中损伤衣物。
其中，如图2所示，加热件5可以设置于送风道4的出口处。
加热件5的类型不唯一，比如，如图2所示，加热件5可以为加热管或者加热棒。另外，加热件5也可以为加热丝。相较于加热丝，加热管或者加热棒更加稳固，不容易在工作时烧断。
风机3的类型也不唯一，比如，如图2所示，风机3可以为离心风机；另外，风机3也可以为轴流风机。相较于轴流风机，离心风机的吸力更大，能够将喷水装置8喷入吸风道7中更多的水吸入并打散；同时由于离心风机是径向出风，离心风机的旋转的叶片31产生的离心力可以方便地将打散的小液滴从径向甩出，从而更加有利于加热件5位置处蒸汽的生成。
本申请实施例提供的具有干衣功能的洗衣机可以为干衣机，也就是不具有洗涤的功能。另外，如图1和图2所示，该具有干衣功能的洗衣机也可以为滚筒洗衣机(也可称之为洗烘一体机)，滚筒洗衣机的滚筒为干衣筒2。这样可以使该洗衣机具有洗涤、烘干、蒸汽熨烫多种功能，以满足用户的需求。
第二方面，本申请实施例还提供了一种用于第一方面中的具有干衣功能的洗衣机的控制方法，包括以下步骤：如图2和图3所示；
S100、控制加热件5进入发热状态，以使温度传感器9所检测的温度值位于预设温度范围内；
其中，加热件5的发热状态不仅包括加热件5通电加热的状态，也包括加热件5断电后具有余热的状态；预设温度范围可以设置为67℃～70℃。
S200、控制风机3、喷水装置8以预设方式工作，以使具有干衣功能的洗衣机进入蒸汽洗涤模式；
其中，在风机3工作之前，控制系统可以对风机3的闭合回路进行检测，以确定风机3是否正常工作，如果风机3回路出现信号异常，则发出报警信号。
S300、当进入蒸汽洗涤模式的时间t满足第一预设条件时，控制喷水装置8处于停止工作状态，并控制风机3以第一预设转速r1运行，以使具有干衣功能的洗衣机进入烘干模式。
其中，第一预设转速r1可以为3800rpm。
本申请实施例提供的具有干衣功能的洗衣机的控制方法所解决的问题以及产生的技术效果，与第一方面中具有干衣功能的洗衣机所解决的问题以及产生的技术效果相同，在此不在赘述。
步骤S200中，风机3、喷水装置8的工作方式有多种，比如在本申请的一些实施例中，步骤S200可以包括以下步骤：如图2和图4所示；
S210、控制风机3以第二预设转速r2运行，并开启喷水装置8；
其中，第二预设转速r2的范围可以为3800-5000rpm。
S220、当喷水装置8的工作时间达到第一预设时长t1时，关闭喷水装置8，并控制风机3以第三预设转速r3运行第二预设时长t2；
其中，第二预设转速r2大于第三预设转速r3，第三预设转速r3的范围可以为600-100rpm；n为正整数；进入蒸汽洗涤状态的时间t等于n(t1+t2)；第一预设时长t1可以为30s，第二预设时长t2可以为1min。
循环执行n次步骤S210～S220，直至进入蒸汽洗涤模式的时间t满足第一预设条件。
在该实施例中，喷水装置8是通过间歇性的工作来保证加热件5所产生的水蒸汽符合要求，并且喷水装置8的工作与停止的切换，是由工作时间与停止 工作的时间来决定的。在步骤S210中，喷水装置8是在风机3处于高速(第二预设转速r2)运行时开启，这样可以保证风机3产生足够的吸力将喷水装置8喷出的水吸入，处于高速运行状态的风机3的叶片31有足够的动力可以将水分散成较小的小液滴，从而以便于后续加热件5将小液滴转化为水蒸气；当喷水装置8工作一段时间后，加热件5的表面因蒸发小液滴会造成温度下降，由于加热件5温度过低会影响水蒸气的生成，因此，在步骤S220中，当喷水装置8的工作时间达到第一预设时长t1时，将喷水装置8关闭，并将风机3的转速调至低速运行(第三预设转速r3)，此时，加热件5可以利用喷水装置8停止工作的这段时间通过通电加热等方式使其温度恢复至预设温度范围，从而保证水蒸气的正常产生。
此外，在本申请的一些实施例中，步骤S200还可以包括以下步骤：
S°210、控制风机3以第二预设转速r2运行，并开启喷水装置8；
S°220、当温度传感器9所检测的温度值低于预设温度范围的下限值时，关闭喷水装置8，并控制风机3以第三预设转速r3运行第二预设时长t2；
循环执行n次步骤S°210～S°220，直至进入蒸汽洗涤模式的时间t满足第一预设条件。
在该实施例中，喷水装置8也是通过间歇性的工作来保证加热件5所产生的水蒸汽符合要求，并且喷水装置8的工作与停止的切换，是由温度传感器9所检测的温度值来决定的。
本申请一些实施例中，在步骤S200执行之前，还可以包括以下步骤：如图2和图3所示；
S80、根据干衣筒2中所放置衣物的重量，确定具有干衣功能的洗衣机的工 作时间T；
其中，确定具有干衣功能的洗衣机的工作时间T可以在步骤S100之前执行，也可以在步骤S100之后执行，在此不做具体限定；洗衣机的工作时间T的范围可以设置为15-45min；在该具有干衣功能的洗衣机为滚筒洗衣机时，可以通过检测驱动电机的输入电流来确定衣物的重量，该驱动电机为驱动滚筒(干衣筒2)转动的电机；除此之外，也可以在干衣筒2中设置力传感器来检测所放置衣物的重量。
S90、控制风机3以第四预设转速r4运行第三预设时长t3；
其中，第四预设转速r4小于第二预设转速r2，第四预设转速r4的范围可以设置为600-100rpm；控制风机3以第四预设转速r4运行可以在加热件5进入发热状态之前执行，也可以在加热件5进入发热状态之后执行，在此不做具体限定；第三预设时长t3可以设置为3min。
在该实施例中，通过衣物的重量来确定具有干衣功能的洗衣机的工作时间T，可以合理分配蒸汽洗涤模式以及烘干模式的时间，避免衣物蒸汽洗涤或者烘干的时间过长或过短；控制风机3以第四预设转速r4(低速)运行第三预设时长t3，可以保证风机3的转速在后续顺利切换至第二预设转速r2(高速)，避免风机3直接进入高速运行所产生的振动。
本申请一些实施例中，在步骤S300之后，还包括以下步骤：如图2和图3所示；
S400、当进入烘干模式的时间满足第四预设时长t4时，控制加热件5、风机3停止工作，以使具有干衣功能的洗衣机进入冷却模式。
其中，第四预设时长t4可以设置为10min。
在该实施例中，通过设置冷却模式，可以在烘干后将衣物冷却一段时间，避免用户在取衣物时被烫伤。
如图3所示，步骤S300中的第一预设条件不唯一，比如在本申请的一些实施例中，第一预设条件可以为：T>t+t3+t4+t5；其中，t5为具有干衣功能的洗衣机进入冷却模式的时长，进入冷却模式的时长t5的范围可以设置为5-10min；也就是：具有干衣功能的洗衣机的工作时间T要大于蒸汽洗涤模式的时间t、烘干模式的时间t4、冷却模式的时间t5以及第三预设时长t3之和。
另外，在本申请的一些实施例中，第一预设条件也可以为：T＝t+t3+t4+t5。当T>t+t3+t4+t5，也就是将具有干衣功能的洗衣机的工作时间T设置得比实际运行的时间长一些，留有一定的时间冗余，这样可以更好地分配各个模式的运行时间。
本申请的一些实施例中，步骤S100可以包括以下步骤：如图2和图5所示；
控制加热件5加热；
当温度传感器9所检测的温度值大于等于预设温度范围的上限值(比如70℃)时，控制加热件5停止加热；
当温度传感器9所检测的温度值小于预设温度范围的下限值(比如67℃)时，控制加热件5加热。
在该实施例中，是通过温度传感器9所检测的温度值来控制加热件5加热与停止，以使温度传感器9所检测的温度值位于预设温度范围内，这样可以准确地控制加热件5的表面温度，以在蒸汽洗涤模式下保证水蒸汽的正常产生，在烘干模式下避免进入干衣筒2内的温度过高损伤衣物。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
