本发明涉及洗衣设备技术领域，尤其是一种具有水加热功能的无孔内筒洗衣机。
背景技术
洗衣机是人们日常生活中比较常用的家用电器之一。洗衣机的使用，为人们的生活带来便利。现有技术中的滚筒洗衣机，外筒盛水，内筒旋转洗涤，内筒壁上设置有孔，用于向内筒中进洗涤水或者用于对内筒中的衣物进行脱水，洗涤水长时间在内外筒之间流动，导致内、外筒的夹层之间会积存脏污、水垢，造成大量细菌繁殖，对衣物造成二次污染，严重威胁消费者的健康，并且内筒和外筒中间夹层之间的水的填充造成无用的水浪费，因此，人们设计了无孔内筒洗衣机。
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，不能通过温度检测装置检测获得洗涤水的加热温度。
有鉴于此，特提出本发明。

进一步地，洗衣机控制面板上设置用于触发处理模块工作的触发单元，所述触发单元可以为操控按键，或者触动开关等，所述触发单元分别与处理模块和控制模块连接，控制模块在接收到触发单元的操控指令后，控制处理模块工作，计算并显示加热温度T。
通过采用上述方案，在加热的过程中，用户若随时想查看加热温度T，可通过操控触发单元，触发处理模块工作，计算并显示加热温度T，满足用户多样化的需求。
进一步地，在一种实施方式中，所述温度获取模块包括用于通讯连接以获得洗衣机进水的初始水温的温度调取模块，所述温度调取模块与智能水龙头和/或热水器通讯连接；所述温度调取模块将调取到的智能水龙头和/或热水器的水温值，反馈至控制模块，作为洗衣机进水的初始水温。
在上述方案，温度获取模块可以调取智能水龙头或者热水器或者智能水表的水温值，作为洗衣机进水的初始水温，无需通过温度传感器检测获得初始水温，简化洗衣机的结构及控制程序，且能够更智能、快捷的获取初始水温，提高洗衣机洗衣的智能性。
或者，温度调取模块可以分别调取智能水龙头的水温值为T 水龙头和调取热水器的水温值为T 热水器，并反馈至控制模块，控制模块计算出洗衣机的初始水温T 0＝(T 水龙头+T 热水器)/2，通过计算二者的平均值作为洗衣机的初始水温，提高初始水温的准确性，减少误差。
或者在另一种实施方式中，所述温度获取模块包括用于直接检测洗衣机进水的初始水温的温度检测装置，所述温度检测装置为安装在洗衣机进水阀处或者进水管路上额度温度传感器，以获得洗衣机进水的初始水温T 0。

实施例二
本实施例主要是对实施例一中，如何通过温度检测装置检测获得初始水温T 0进行详细说明。
参见图3所示，本实施例提供了一种洗衣机，包括：内筒17，洗涤衣物时独立盛放洗涤水；进水系统，所述进水系统与所述内筒17连通；温度检测装置(图中未示出)，设置在进水系统内检测进水温度。通过在进水系统内设置的温度检测装置可以实时检测到进水的温度，保证洗衣机的控制系统对内筒17中的水温进行控制进而达到较好的洗涤效果。
在上述方案中，所述洗衣机还包括设置在进水系统内检测进水量的流量检测装置(图中未示出)；优选地，所述温度检测装置为温度传感器，所述流量检测装置为流量传感器。通过流量传感器的计量向内筒17中进水量，保证洗衣机的控制系统对内筒17中的水量进行控制达到较好的洗涤效果，流量传感器实时监测内筒17内进水时的流量。本实施例采用流量传感器解决了无孔内筒滚筒洗衣机根据设定进水量的进水问题，确保了洗涤效果，结构简单，操控方便。

为了保证测量温度的精准度，可以通过采用求平均值的方式，得出内筒内的初始水温t 0，具体的，所述初始水温t 0＝(t 1+t 2+t 3+t 4+……tn)/n，其中n≥3；t 1～tn为在洗衣机进水过程中，温度检测装置在不同时间检测到的不同水温值。
优选地，所述温度检测装置在每间隔一定时间检测一次初始水温值，进一步提高测量的初始水温t 0的准确度，避免在集中时间测量的水温值与实际平均水温值会存在较大的偏差。
当洗衣机执行水加热程序时，洗衣机的控制单元根据温度检测装置检测到的进水的初始温度结果、以及获取洗衣机的进水量及加热时间，洗衣机根据水加热公式：T＝(P*t)/(C*m)+T 0获得到水的加热温度，在判断到计算的洗涤水的加热温度T达到目标加热温度T 目标时，停止加热，避免了电磁加热装置的加热温度过高，不及时切断电磁加热装置，对洗涤衣物造成损伤，造成一定的安全隐患。或者加热温度过低，影响洗涤效果。此外，在加热过程中实时显示计算得到的加热温度值，便于用户直观获取加热的温度信息，提升用户的使用体验。
