随着人们生活质量的不断提高，人们对洗衣机洗衣效果的要求也越来越高。因此，用户在洗涤过程中一般都会对洗涤水进行加热，不仅可以提高洗涤剂的去污能力，同时加热的洗涤水还可以对衣物杀菌消毒，因此，具有水加热功能的无孔内筒洗衣机备受青睐。在外筒内设置加热装置，通过控制加热装置将洗涤水加热到设定的温度值，在这一过程中，需要对洗涤水的温度进行检测，确保洗涤水能够加热到设定的温度值。
一般洗衣机是通过设置在外筒内温度传感器获取洗涤水的加热温度，然而，由于无孔内筒洗衣机在内筒和外筒之间无水，是很难通过设置在外筒上的温度传感器来检测内筒内洗涤水的加热温度的。并且由于无孔洗衣机的内筒是为可转动设置的，内筒里无法安装温度检测装置，不能通过设置在内筒内的温度检测装置直接检测获得洗涤水的加热温度。

下面结合实施例对本发明进行进一步地详细的说明。
如图1所示，本实施例提供了一种洗衣机，包括：内筒1，洗涤衣物时独立盛放洗涤水；加热装置，加热所述内筒1内的洗涤水；集水装置3，设置在内筒1外，内筒1中的洗涤水可被排出至所述集水装置3内，所述集水装置3内设置有测温元件，通过所述测温元件对集水装置3内收集的洗涤水进行测温，进而得出内筒1内洗涤水的温度。本实施例通过对集水装置3内收集的洗涤水进行测温得出内筒1内的加热水温，测温方法简单高效，易于实现，有效地解决了无孔内筒洗衣机洗涤水加热温度检测困难的问题。
在一种实施方式中，所述洗衣机还包括同轴设置在内筒1外的外筒2，所述集水装置3为外筒2，外筒2内设置有测温元件，在进行加热的过程中，通过将内筒1中的洗涤水排出至外筒2内，通过外筒2内设置的测温元件对外筒2内收集的洗涤水进行测温，进而得出内筒1内洗涤水的温度。通过将外筒2作为集水装置3，一物多用，无需额外增设集水装置3，简化了洗衣机的结构。
或者，在另一种实施方式中，所述集水装置3为设置在外筒2内，所述集水装置3内设置有测温元件，在加热的过程中，可通过将内筒1中的洗涤水排出至外筒2内的集水装置3内，再通过测温元件对集水装置3内收集的洗涤水进行测温，进而得出内筒1内洗涤水的温度。通过在外筒2内单独设置的集水装置3，对内筒1中排出的洗涤水进行收集测温，测温效果更精准，且内外筒之间不会积存杂质水垢，提升洗衣机的清洁效果。
或者，在另一种实施方式中，所述集水装置3为连接在洗衣机的排水管路上的 集水结构，所述集水装置3内设置有测温元件，在加热的过程中，内筒1内的部分洗涤水通过洗衣机的排水管路排出至集水装置3内，再通过设置在集水装置3内的测温元件对集水装置内的洗涤水进行测温，进而得出内筒1内洗涤水的温度。本实施方式中，所述集水装置3与洗衣机的排水管路连通，通过借助内筒1上的排水阀等排水结构即可实现向集水装置3排水，无需额外再在内筒1开设排水孔、设置排水阀等结构，在能够实现测温目的的同时，简化了洗衣机的结构。
进一步地，所述测温元件为设置在集水装置3内的温度传感器31，所述温度传感器31对进入到集水装置3内的洗涤水的温度进行测温，并将测温结果反馈至洗衣机的控制单元。通过温度传感器31对集水装置3中的水温进行检测，向洗衣机的主控制器提供集水装置3当前的加热水温，便于主控制器对内筒1中的水温进行控制，以达到较好的洗涤效果。
本实施例中，所述温度传感器31为电阻式温度检测器；或者，为半导体传感器；或者，为热电偶；或者，为NTC温度传感器。较为优选地，为NTC温度传感器，其是由具有负温度系数的热敏电阻与导线连接而成，利用NTC热敏电阻在一定的测量功率下，电阻值随着温度上升而迅速下降。利用这一特性，可将NTC热敏电阻通过测量其电阻值来确定相应的温度，并通过信号线传输至洗衣机的主控制器，从而达到检测和控制内筒1内水温的目的。
需要说明的是，所述集水装置3无论是外筒2，还是为外筒2内/外设置的单独构件，均能够实现通过对集水装置3内收集的洗涤水进行测温，得到内筒1内洗涤水温度的目的。优选地，本实施例中以所述集水装置3为外筒2内的单独构件为例进行详细说明。
具体地，所述内筒1的周壁上开设有可将内筒1内的洗涤水排出至集水装置3内的排水孔，所述集水装置3设置在外筒2内壁上形成对应所述排水孔的集水腔室，所述集水装置3靠近所述排水孔侧设有接水口。所述排水孔呈打开状态时，内筒1内的洗涤水在重力/离心力的作用下，由所述排水孔排出，经所述接水口排至集水装置3的集水腔室内。
在一种方案中，所述集水装置3为设置在外筒2内的独立构件，所述集水装置3包括独立具有集水腔室的壳体结构，所述集水装置3包括固定在外筒2内壁的外侧底壁、以及连接在外侧底壁外周的周侧壁、以及靠近内筒1侧的内侧壁，所述集水 装置3的外侧底壁、周侧壁以及内侧壁内部形成所述集水腔室。所述集水装置可以直接螺纹连接或者卡接安装在外筒2的内壁上，或者也可以通过支架、支杆等支撑结构支撑固定在外筒2的内壁上。
或者，在另一种方案中，所述集水装置3包括与外筒2的内壁共同构造形成集水腔室的壳体结构，所述集水装置3包括直接连接在外筒2内壁的上下端开口的周侧壁、以及连接在周侧壁靠近内筒1开口侧的内侧壁，所述集水装置3的周侧壁、内侧壁与外筒2的内壁共同围合形成所述集水腔室。
优选地，所述集水装置3靠近所述排水孔侧具有与内筒1外周壁弧度相同的弧形内侧壁，所述弧形内侧壁与内筒1的外周壁平行间隔设置，所述弧形内侧壁贴近所述内筒1的外周壁，且与内筒1的外周壁之间具有一定的间隙空间，以避免集水壳与内筒1的周壁接触干扰内筒1的转动。
所述接水口开设在所述弧形内侧壁上，所述接水口在内筒1周壁上的投影覆盖所述排水孔，即所述排水孔位于所述接水口在内筒1周壁上的投影范围内；或者，所述集水装置3靠近所述排水孔侧为敞口设置，所述集水装置3的敞口端形成所述接水口，所述集水壳为一侧敞口的槽状结构。
优选地，沿着内筒1的长度方向，所述排水孔开设在内筒1筒体的中间周圈位置，所述排水孔开设在内筒1的中间位置，相比于开设在前后两侧，中间位置的洗涤水仅与内筒1筒体接触，不会与内筒底或者内筒门接触，热量损失相对较少，筒体中部的水温更具代表性，测温结果更准确。
更优地，所述集水装置3安装在外筒2的最底部，所述温度传感器31设置在集水装置3的最底部，通过上述设计，即使内筒1排出较少量的洗涤水，也会在重力的作用下汇集至集水装置3的最底部，通过温度传感器31对其进行测量。
优选地，本实施例中，所述集水装置3的集水壳采用保温性能较好的材料制成，或者设置有保温夹层，以减少集水腔室内收集的洗涤水的热量损失，减少测量误差。
本实施例提供的洗衣机，内筒1中的洗涤水可以通过以下两种方案排出至外筒2内的集水装置3内。
第一种方案
如图1所示，本方案提供的洗衣机，内筒1内的洗涤水在重力的作用下排出至 集水装置3内。
具体地，所述集水装置3安装在外筒2的最底部，所述排水孔呈打开状态时，内筒1内的洗涤水在重力的作用下可直接自动排出至集水腔室内。通过上述设计，无需通过离心力的作用将内筒1中的水甩出至集水装置3，利用重力的作用，内筒1内的洗涤水可直接排出至集水装置3内，排水方法更加简单。
所述排水孔上安装有常闭的排水阀11，所述排水阀11为内筒1的内部且位于内筒1上的提升筋12的内部空腔内，通过将所述排水孔开设在提升筋安装区域内、所述排水阀11设置在提升筋12内，一方面用户从内侧看不到所述排水孔和排水阀11，提升洗衣机的美观性，另一方面也有效地避免了将排水孔开设在提升筋安装区域以外的内筒1周壁上，内筒1内的衣物会在重力的作用下堆积在所述排水孔上，会阻碍干涉所述排水阀11开启，出现内筒1中的洗涤水很难向集水装置3排放的现象。
此外，通过将排水孔和排水阀11隐藏设置在提升筋12的空腔内，提升筋12的壳体会对所述排水阀11起到一定的支撑保护作用，使得排水阀11在提升筋12的空腔内有足够的自由活动空间，避免排水阀11与其他部件产生摩擦损伤。
所述外筒2上安装有可将排水阀11顶开进行排水的顶杆机构32，所述顶杆机构32包括顶杆和驱动所述顶杆伸缩运动的顶杆电机；所述顶杆在顶杆电机的驱动下，伸入到所述排水孔内，顶开所述排水阀11，将内筒1中的洗涤水被排出至所述集水装置3内。
所述顶杆与所述排水孔的位置对应，所述顶杆的外径小于所述排水孔的内径，所述顶杆穿过所述集水壳且具有一定的纵向延伸长度，所述顶杆在顶杆电机的驱动下向上运动伸入到所述排水孔内，将所述排水阀11打开，向集水装置3内排水，在集水装置3内达到预设的水量时，所述顶杆电机带动顶杆向下运动，所述排水阀11复位封堵在所述排水孔上。
进一步地，所述的外筒2上还设置用于锁止内筒1转动的锁止机构，所述锁止机构将内筒1锁止后顶杆机构32将排水阀11顶开向集水装置3内进行排水。通过设置的锁止机构能够使得排水孔与集水装置3的接水口能够精准定位、对齐，避免由于排水孔与接水口的位置不对应或者存在偏差，导致洗涤水被排到集水装置3外，不仅造成浪费，还会影响洗涤效果及测温效率。
具体地，所述的锁止机构安装在外筒2上靠近驱动电机4的侧壁上，锁止机构 包括伸缩运动的锁止杆和驱动锁止杆伸缩运动的锁止电机，所述驱动电机4的转子上对应锁止杆设置与其配合的锁止槽，当锁止杆在锁止电机的驱动下伸出插入锁止槽内时，内筒1被锁止。
优选地，还包括用于检测内筒1转动位置的位置检测装置，在所述位置检测装置检测到内筒1上的排水孔与集水装置3的接水口位置对应时，所述锁止机构动作将内筒1位置锁定，通过设置的位置检测装置进一步保证了排水孔与接水口位置的对应性。

作为本实施例的一种实施方式，所述的位置传感器为电磁式位置传感器，或者光电式位置传感器，或者差动电压式传感器，或者电涡流式传感器，或者电容式传感器，或者干簧管式传感器，或者霍尔式传感器。
第二种方案
本方案提供的洗衣机，内筒1内的洗涤水是在离心力的作用下排出至集水装置3内。
具体地，所述排水孔上安装有离心阀，所述集水装置3包括设置在外筒2内的弧形/环形壳体结构，所述接水口为沿着内筒1的旋转方向设在所述弧形/环形壳体结构上的弧形/环形接水口。
优选地，所述集水装置3为设置在外筒2内的一环形壳体结构，所述集水装置3内具独立的集水腔室或者与所述外筒2的内壁共同构成所述集水腔室，所述接水口为对应所述排水孔的位置开设的环形接水口。
通过控制内筒1转速达到或者超过设定转速N0，离心阀受到离心力将排水孔打开，内筒1内的洗涤水在离心力的作用下甩出至集水装置3内，通过测温元件对集水装置内收集的洗涤水的温度进行检测，进而得出内筒1内洗涤水的温度。
优选地，所述弧形/环形接水口的两侧边沿上设有逐渐外扩设置的导向接口结构 通过设置的导向接口结构起到汇集引导水流的作用，提高洗涤水收集的效率，同时也有避免从所述排水孔排出的洗涤水甩至集水装置3外，造成浪费的问题。
更优地，所述导向接口结构为与内筒1的周壁弧度相同的弧形状结构，所述导向接口结构为沿着所述接水口逐渐向外延伸设置的弧形外扩结构，起到较好的收集水流的作用，所述导向接口结构贴近所述内筒1的外周壁设置，且具有一定的间隙，在最大限度地保证洗涤水外泄的作用的同时，避免干涉到内筒1的转动。
通过上述两种方案，均可实现本发明中向集水装置3排放部分洗涤水的目的，通过洗衣机排水管路向集水装置3排水的方案与洗衣机正常排水的控制方式相同，因此再此酒不再赘述。
本实施例中，所述内筒1的内壁具有用于安装提升筋12的提升筋安装区域，所述排水孔开设在位于提升筋安装区域内的内筒1周壁上。通过将排水孔开设在位于提升筋安装区域的内筒1周壁上，一方面提升筋12会将排水孔覆盖，隐藏所述排水孔的设置，提升洗衣机的美观性。另一方面也有效地避免了将排水孔开设在提升筋安装区域以外的内筒1周壁上，内筒1内的衣物会在重力的作用下堆积在所述排水孔上，会阻碍干涉排水阀11或者离心阀的打开。
所述提升筋安装区上安装有提升筋12，通过设置的提升筋12用于内筒1中的衣物提升，提升到一定高度时衣物被抛落，形成对衣物的摔打洗涤，具有拨水和摩擦衣物的功能，提升衣物的洗涤效果。
所述提升筋12内部具有与所述排水孔连通的空腔，所述提升筋12上开设有多个连通所述空腔和内筒1内部腔室的过水孔。内筒1内的洗涤水可通过提升筋12上的过水孔进入到提升筋12的内部空腔内再由所述排水孔排出至集水装置3内。
所述排水阀11或者离心阀均设置在提升筋12内，通过将所述排水阀11或者离心阀设置在提升筋12内，一方面用户从内侧看不到所述排水阀11或者离心阀，提升洗衣机的美观性，此外，通过将排水阀11或者离心阀隐藏设置在提升筋12的空腔内，提升筋12的壳体会对所述排水阀11或者离心阀起到一定的支撑保护作用，使得排水阀11或者离心阀在提升筋12的空腔内有足够的自由活动空间，以打开所述排水孔。
本实施例中，所述加热装置为安装在机壳或者外筒2上的电磁加热装置，所述电磁加热装置通过电磁加热的方式加热所述内筒1，进而加热内筒1内的洗涤水。采 用电磁加热装置对内筒1进行加热，进而加热内筒1中的衣物以及内筒1中的洗涤水，结构简单，装配效率高，提高了产品的实用推广。
具体地，所述电磁加热装置包括电磁加热线圈和整流器，加热程序启动，电流电压经过整流器转换为直流电，使得直流电变为超过音频的高频交流电，将高频交流电输出给所述电磁加热线圈上，由此产生高频交变磁场，其电磁感应线作用在金属材质的外筒2上，在金属内筒1内因电磁感应就有强大的涡流产生，涡流克服内筒1的内阻流动时完成电能向热能的转换，实现内筒1发热，进而实现加热内筒1内封装的洗涤水的目的。
进一步地，所述集水装置3还包括可将集水腔室内收集的洗涤水排出的集水排水管路，所述集水排水管路上设置有控制阀。所述集水排水管路可直接与洗衣机的排水系统连接，在温度传感器31测温完毕后，控制所述控制阀打开，将集水装置3内的洗涤水随着洗衣机的排水系统排出。
优选地，所述集水排水管路上还设置有循环泵，所述集水排水管路与洗衣机的进水系统连通，所述集水排水管路的出水端与洗衣机的进水管路或者进水盒等进水结构连通，所述集水装置3内收集的洗涤水在循环泵的作用下可被抽吸循环回至内筒1内。
通过上述设计，使得所述集水装置3内的洗涤水能够再次循环回至内筒1内进行洗涤利用，避免被加热的洗涤水直接排出，造成的能源浪费的问题，进一步降低了测温的成本，节约了水资源。
如图1、图2所示，本实施例还提供了一种具有上述洗衣机的控制方法，在加热的过程中，控制内筒1中的洗涤水排出至集水装置3内，并通过测温元件对集水装置3内收集的洗涤水进行测温，进而得出内筒1内的洗涤水温度。
具体地，在内筒1进水完毕后，控制加热装置启动加热内筒1内的洗涤水；在加热的过程中，控制内筒1中的洗涤水排出至集水装置3内，并对集水装置3内收集的洗涤水进行测温；所述洗衣机的控制单元根据集水装置3内洗涤水的测温结果得出内筒1内洗涤水的加热温度，并根据得到的内筒1内的洗涤水的加热温度来控制加热装置的工作情况。
通过对集水装置3内洗涤水的温度进行检测，可以直接转换为内筒1内洗涤水的温度，洗衣机的控制单元判断当前的加热水温是否达到目标温度T 目标，若是则可 控制加热装置停止加热，若否则可控制加热装置保持通电，继续加热，或者也可以根据当前检测到水温值与目标温度T 目标的差值大小，来控制是否需增大或减少加热装置的功率等。例如，在判断到当前的水温值与目标温度T 目标相差较大时，可以增大加热装置的加热功率，以提升加热效率。
或者，在另一种实施方式中，沿着内筒1筒体的长度方向，在外筒2上间隔设置有多个集水装置3，内筒1筒体上对应间隔设有多个排水孔，所述温度传感器31对应为多个，一一对应设置在集水装置3内。
通过对内筒1内不同位置的洗涤水进行测温，多个温度传感器31将检测到的温度值T 1、T 2、T 3、、、T n分别传输给洗衣机的控制单元，所述控制单元计算分析得出内筒内的水温T 1′、T 2′、T 3′、、、T n′，其中，当前水温T n′＝x·T n+c，x为系数，c为常数，n≥1。洗衣机的控制单元计算得出内筒1内洗涤水的平均水温T′＝(T 1′+T 2′+T 3′+、、、T n′)/n，同时判断是否到达目标温度T 目标，若是，则控制加热装置断电；若否，则控制加热装置保持通电继续加热。
上述方法中，通过设置的多个集水装置3对内筒1内不同部位的洗涤水进行检测，通过求平均值的方法计算得出内筒1内洗涤水的平均温度，测量误差更小，测量结果更准确。
进一步地，在加热的过程中，所述集水装置3每间隔一定的预设时间检测一次内筒1中的加热水温。或者，在加热装置开始加热后的设定t 1时间后，再通过所述集水装置3每间隔一定的预设时间检测一次内筒1中的加热水温，目标加热温度T 目 标越高，设定的t 1时间越长，减轻集水装置3的工作量，降低能耗。
优选地，洗衣机的显示屏每间隔一定的预设时间显示一次集水装置3检测到的洗涤水的加热温度，给用户以更直观的参考，提升用户的使用体验。
更优选地，在控制加热装置启动的同时控制内筒1缓慢转动，以使内筒1进行均匀受热；在达到预设的检测时间时，控制内筒1转动至排水孔与集水装置3的接水口位置对应的位置。具体地，所述位置检测装置检测内筒1的位置，在判断到内筒1转动至排水孔与接水口的位置对应时，控制锁止机构动作将内筒1锁止。
所述锁止机构将内筒1锁止后，控制顶杆机构32将排水阀11顶开，即控制所述顶杆电机工作，驱动所述顶杆向上运动，将排水阀11顶开，排水孔被打开，内筒1中的洗涤水会流向集水装置3内。在判断到集水腔室内收集的洗涤水达到设定值时， 温度传感器31开始检测集水装置3内的水温，并反馈至控制单元，控制单元根据测温结果控制加热装置的通断。
更选地，在每次测温后，控制集水排水管路上的控制阀和循环泵打开，将集水腔室内的水循环回至内筒1内。通过上述方法，将集水装置3内的水再次循环回至内筒1内继续洗涤利用，避免了被加热的洗涤水直接排出造成的能源浪费的问题，降低了洗衣成本，用户体验更好。
在另外一种控制方法中，如图3所示，通过离心排水的方法将内筒1中的洗涤水甩出至集水装置3内，在达到预设的检测时间时，控制内筒1转速达到或者超过设定转速N 0，使得离心阀受到离心力将排水孔打开，内筒1内的洗涤水在离心力的作用下甩出至集水装置3内；在集水装置3内收集的洗涤水达到设定量时，所述测温元件开始对集水装置3内收集的洗涤水的温度进行检测，并将检测结果反馈至洗衣机的控制单元，进而得出内筒1中洗涤水的温度。
本实施例提供的上述两种洗衣机的控制方法，测温方法简单高效，易于实现，有效地解决了无孔内筒洗衣机洗涤水加热温度检测困难的问题。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案做出的各种变化和改进，均属于本发明的保护范围。
