Description

一种衣物处理设备的控制方法及衣物处理设备 技术领域
本发明属于衣物处理设备技术领域，具体地说，涉及一种衣物处理设备的控制方法及衣物处理设备。
背景技术
随着人们生活水平的日益提高，人们对衣物的洗护需求种类也越来越丰富。例如，现今大多数洗衣机都提供了洗涤水加热功能，在开始洗衣前对内筒中的洗涤水进行加热，从而采用温度更高的温水或热水对衣物进行洗涤，可以增强衣物的洗涤效果。而现有技术中，为实现对洗涤水加热温度的控制，同时也为了及时获知加热装置工作状态，避免出现过热风险，一般通过设置温度传感器并在加热过程中持续获取洗涤水的温度。
然而近年来，洗衣机行业均进行无孔内筒洗衣机的开发，不同于传统的洗衣机在洗涤过程中通过外筒盛水，内筒盛放衣物，其在内筒上不再设置脱水孔，使得内筒在洗涤过程中可以独立盛放洗涤水。通过上述方式可以避免洗涤过程中内、外筒之间存水的情况，节省了洗涤水的用量，同时也很大程度上避免了内、外筒之间的脏污积累，从而避免了内、外筒之间的脏污进入内筒中污染衣物的情况，实现了洗衣干净卫生。但由于洗涤过程中内筒与外筒之间无水，无法通过传统洗衣机中在外筒内设置加热管的形式对洗涤水进行加热，同样也无法通过在外筒内设置温度传感器的方式实现洗涤水温度的检测。
为解决这一问题，目前主要应用电磁加热技术对由含铁质材料制成的内筒进行无接触加热，从而实现加热洗涤水的目的。在上述内、外筒间无水的洗衣机中，洗涤水的加热通过安装在内筒外部的电磁加热模块完成，电磁加热模块自身不与洗涤水接触。但这一加热方式也造成了一定的风险，如电磁加热模块自身的散热出现故障时可能产生较高温度，或者在洗衣机出现进水异常导致内筒中水位不足时，内筒在电磁加热模块作用下自身快速升温可能损伤衣物甚至引发火灾。因此，针对采用电磁加热模块的洗衣机，如何保证加热过程中的安全性，及时发现故障的发生显得尤为重要。
另一方面，在上述内、外筒间无水的洗衣机中，安装在外筒上的温度传感器也无法直接与洗涤水接触，只能通过测量内、外筒之间的环境温度间接获取洗涤水的温度，准确性较差，无法实现对洗涤水加热温度的精确控制。
与之类似，在具有干衣功能的衣物处理设备运行干衣程序时，温度检测装置也只能获取衣物处理筒内部或外部一定区域的环境温度，而无法实现整体烘干温度的准确获取，进而对烘干温度的控制不够准确，也可能无法及时发现加热过程中的过热故障。
有鉴于此，特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种衣物处理设备的控制方法及衣物处理设备，可根据所需达到的目标加热温度T计算出所需的加热时间t，并在加热过程中的一个或多个时刻对温度进行检测，用于判断是否出现加热故障，从而可以在发生加热故障时及时做出响应，提高了加热安全性。

进一步地，温度检测装置在加热装置的加热过程中持续进行温度检测操作，当检测到的实时温度T’与预设温度T 0’一致时，获取当前时间节点下加热装置的持续加热时间t 2；
衣物处理设备预设有达到预设温度T 0’所需的持续加热时间取值范围，若当前的持续加热时间t 2超出所述持续加热时间取值范围时，判定出现加热故障；
优选地，衣物处理设备预存持续加热时间取值范围与目标加热温度T的取值的对应关系，获取目标加热温度T后，根据持续加热时间取值范围与T的对应关系调取相应的持续加热时间取值范围，用于与持续加热时间t 2进行比较；
优选地，衣物处理设备预存预设温度T 0’的取值与目标加热温度T的取值的对应关系；获取目标加热温度T后，根据T 0’与T的对应关系调取相应的预设温度T 0’的取值，用于在加热过程中获取对应的持续加热时间t 2。
进一步地，衣物处理设备获取目标加热温度T后，与预设目标温度T 0进行比较；
若T>T 0，加热装置启动后，温度检测装置间歇进行温度检测操作，根据检测到的实时温度T’以及加热装置执行加热操作的持续加热时间t 1计算升温速率v，并根据升温速率v判断是否出现加热故障；
若T≤T 0，温度检测装置在加热装置的加热过程中持续进行温度检测操作，获取实时温度T’达到预设温度T 0’时的持续加热时间t 2，并根据持续加热时间t 2判断是否出现加热故障。
进一步地，根据加热公式P*Φ*t＝k*m*(T-T 1)计算得到加热时间t，其中，k为与被加热物质相关的加热系数，Φ为加热装置将电能转化为热能的效率，且Φ<1；
优选地，衣物处理设备根据目标加热温度T的取值大小确定效率Φ的取值；
更优地，衣物处理设备预存目标加热温度T的取值与效率Φ的取值的对应关系，获取目标加热温度T的取值后，根据T与Φ的对应关系调取相应的效率Φ的取值，用于计算加热时间t。
进一步地，若所述负载量m为进水量，初始温度T 1为进水温度，所述加热公式中，加热系数k根据公式k＝ξ*c 0计算得到；其中，c 0为水的比热容，ξ为与衣物材质相关的修正系数；
优选地，衣物处理设备预存衣物的材质信息与修正系数ξ的取值的对应关系；衣物处理设备获取待洗衣物的材质信息，根据材质信息与ξ的对应关系调取相应的修正系数ξ的取值，用于计算加热时间t。
进一步地，在每次检测得到实时温度T’后，若判定出现加热故障，则控制加热装置停止加热，衣物处理设备发出报警信号；否则，当加热装置执行加热操作的持续时间达到加热时间t时，控制加热装置结束加热操作。
本发明的另一目的是提供一种衣物处理设备，采用上述所述的衣物处理设备的控制方法。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明的衣物处理设备可根据所需达到的目标加热温度T计算出所需的加热时间t，并在加热过程中的一个或多个时间节点对温度进行检测，用于判断是否出现加热故障。以上控制方法既可以用于控制内筒独立盛水的洗衣机的洗涤水加热过程，也可以用于控制衣物处理设备的运行干衣程序时的加热过程，从而可以在发生加热故障时及时做出响应，提高了加热安全性。
本发明的衣物处理设备通过温度检测装置获取加热过程中的升温速率v，或者达到加热预设温度T 0’所需的持续加热时间t 2，当升温速率v过快，或持续加热时间t 2过短时，说明出现了加热故障，存在过热风险，可以及时停止加热，避免安全事故的发生。当不存在加热故障时，通过计算得到的加热时间t控制加热装置结束加热操作，可以较为准确地控制加热过程最终达到目标加热温度T。
本发明的衣物处理设备中，当目标加热温度T较低时，所需的加热时间t较短，升温速率v变化较小，采用持续加热时间t 2进行判断更容易实现；当目标加热温度T较高时，所需的加热时间t较长，采用升温速率v进行判断可避免温度检测装置长时间持续工作，从而可以延长其使用寿命。衣物处理设备可根据目标加热温度T的取值自动选择采用升温速率v或持续加热时间t 2用于判断是否出现加热故障，自动化程度高。
本发明的衣物处理设备中，将电能至热能的转化效率，以及衣物材质对洗涤水比热容的影响均计入加热时间t的计算中，计算得到的加热时间t更加符合实际情况，从而可以使洗涤水被加热的温度控制更加准确。

以下通过不同实施例分别对上述控制方法在不同加热过程中的应用进行说明。
实施例一
本实施例提供一种衣物处理设备及其控制方法，所述控制方法具体用于衣物处理设备运行洗衣程序时的洗涤水加热过程。
如图1至图2所示，本实施例的衣物处理设备包括外壳100，以及设置在外壳100内的外筒200和内筒300，内筒300可转动的同轴设置在外筒200内部，可独立盛放洗涤水。
具体地，内筒300的筒壁上不设置脱水孔，筒口处设置可打开/关闭的内筒门320，在洗涤过程中内筒门320关闭，内筒300内部形成封闭状态，可以独立盛放洗涤水。内筒300的筒壁上设置排水孔，排水孔在洗涤过程中被密封组件封堵，在内筒300达到一定转速时，密封组件可以在离心力的作用下打开排水孔，实现洗涤水的排出。
详细地，内筒300的筒壁上对应排水孔的位置安装有提升筋310，提升筋310的壳体上开有孔，提升筋310内部内集成设置离心排水结构，离心排水结构的初始状态为封堵状态，保持内筒300封闭独立盛放洗涤水，在离心力作用下离心排水结构可开启，使得洗涤水能够通过排水孔排出。
外筒200的筒底具有中心安装孔，其中固定安装轴承结构。与内筒300紧固连接的驱动轴穿过所述轴承，与位于外筒200的筒底外侧的电机输出轴连接。所述驱动轴具有中空结构，驱动轴的中空结构与进水管连通，用于向内筒300中进水，驱动轴与进水管的连接处具有动密封结构。外筒200的底部连通排水装置400，从内筒300排出的水经过外筒200进入排水装置400，再经由与排水装置400连通的排水管410排出衣物处理设备的外壳100。
衣物处理设备上部具有控制面板130，外壳100的上表面为上台面板120，上台面板120下方位于外壳100内部还设有洗涤剂盒150，用于实现洗涤剂向内筒300的自动添加。外壳100的前侧设置可打开/关闭的机门110，用于实现衣物的取放。外壳100的底部安装底脚140，用于支撑整个衣物处理设备。
本实施例中，为实现洗涤水的加热功能，衣物处理设备中还设置加热装置。具体地，所述加热装置为电磁加热装置500，内筒300的筒壁由含铁质材料制成。当电磁加热装置500的线圈510中被通入高频交流电时，可产生高频交变磁场，其磁感线作用在内筒300的筒壁上，可激发内筒300的筒壁产生涡流。涡流克服内筒300的内阻流动时完成电能向热能的转换，实现内筒300自身发热，进而将产生的热量传递至内筒300中的洗涤水，实现洗涤水的加热。加热过程中，内筒300在外筒200中转动，使内筒300的筒壁均匀发热，从而将热量均匀地传递至洗涤水。
本实施例的优选方案中，线圈510由铜导线呈螺旋状绕制形成若干同心圆，电磁加热装置500还包括由绝缘材料制成的封装壳体520，将线圈510包覆于封装壳体520内部，避免洗涤水与线圈510接触，提高电磁加热装置500的可靠性和安全性。
本实施例中，封装壳体520包覆的线圈510整体安装在外筒200内部，位于内筒300的下方靠近外筒200筒底的区域。外筒200上与排水装置400连通的排水口设置在外筒200底部靠近筒口的区域，与电磁加热装置500的安装互补干扰。封装壳体520上具有与外筒200卡接或紧固的固定结构。优选在封装壳体520内部线圈510的下方还设置若干磁条，用于屏蔽向下辐射的磁感线，减少磁场的外泄，保证电磁加热装置500的加热效率。
本实施例的另一种方案中，电磁加热装置还可以设置在外筒下方，外筒由不受磁场激发的绝缘材料制成，电磁加热装置产生的磁感线可穿透外筒作用在内筒上。
本实施例中，电磁加热装置500的线圈510与位于封装壳体520外侧的接线端子连接，所述接线端子通过导线与位于外筒200外部的整流器530连接。具体地，整流器530与衣物处理设备的供电线连接，将供电线输送的家用交流电转变为直流电，再经过IGBT功率管转 变为高频交流电，沿穿过外筒200筒底的导线输入线圈510中。
本实施例的进一步方案中，为实现洗涤水加热温度的控制，在外筒200上安装有温度检测装置210，温度检测装置210的检测端位于内筒300与外筒200之间，用于检测内筒300与外筒200之间的温度。在洗涤水被加热的过程中，由于内筒300自身发热，内筒300与外筒200之间的环境温度也相应上升，通过温度检测装置210检测内筒300与外筒200之间的环境温度，一定程度上可以反映洗涤水被加热的温度状态。
温度检测装置210可以为红外温度传感器、热电偶等可实现温度检测的传感器。
但在上述方案中，洗涤水温度由温度检测装置210测量内筒300与外筒200之间的环境温度间接获得，由于所述环境温度还会受到诸多因素的影响，无法精确得出洗涤水的实际温度，导致对洗涤水温度的控制准确性较差，难以实现最优的洗涤效果。
为此，如图3所示，本实施例还提供了一种上述衣物处理设备的控制方法，包括：
衣物处理设备获取进水量m，进水温度T 1，以及目标加热温度T；
根据所述进水量m，进水温度T 1，以及目标加热温度T计算出达到所述目标加热温度T所需的加热时间t；
控制加热装置启动执行加热操作；
在达到加热时间t之前，控制温度检测装置进行至少一次温度检测操作，根据温度检测装置检测得到的实时温度T’判断是否出现加热故障。
在上述方案中，目标加热温度T由衣物处理设备接收用户的设置信息获取，在衣物处理设备的进水管上分别设置流量传感器和温度探头，所述流量传感器用于检测进水量m，温度探头用于检测进水温度T 1。衣物处理设备可根据洗涤水所需达到的目标加热温度T计算出所需的加热时间t，并在加热过程中的一个或多个时间节点对温度进行检测，用于判断是否出现加热故障，从而可以在发生加热故障时及时做出响应，提高了加热安全性。
具体地，本实施例中，在每次检测得到实时温度T’后，若判定出现加热故障，则控制加热装置停止加热，衣物处理设备发出报警信号。否则，当加热装置执行加热操作的持续时间达到加热时间t时，控制加热装置结束加热操作。
在上述方案中，当出现加热故障时，由于存在过热风险，衣物处理设备可及时停止加热，从而避免安全事故的发生。当不存在加热故障时，衣物处理设备通过计算得到的加热时间t控制加热装置结束加热操作，相比于通过检测内筒与外筒之间的温度判断是否洗涤水温度达 到目标加热温度T的方式，可以更加准确地控制洗涤水达到目标加热温度T。
本实施例的具体方案中，衣物处理设备根据加热公式P*Φ*t＝k*m*(T-T 1)计算得到加热时间t。其中，P为加热装置的加热功率，k为与被加热物质相关的加热系数，本实施例中即为洗涤水的比热容，Φ为加热装置将电能转化为热能的效率，且Φ<1。也即，加热时间t＝k*m*(T-T 1)/(P*Φ)。
优选地，衣物处理设备根据目标加热温度T的取值大小确定效率Φ的取值。对应用户设定的不同的目标加热温度T，加热装置将电能转化为热能的效率Φ也不相同。一般情况下，T的取值越高，Φ的取值越小。
更优地，衣物处理设备预存目标加热温度T的取值与效率Φ的取值的对应关系，获取目标加热温度T的取值后，根据T与Φ的对应关系调取相应的效率Φ的取值，用于计算加热时间t。所述的T与Φ的对应关系通过预先进行的大量实验测试得出，直接写入衣物处理设备的控制系统中，在衣物处理设备运行加热程序时直接调用，便于控制。
本实施例的进一步方案中，所述加热公式中，加热系数k根据公式k＝ξ*c 0计算得到。其中，c 0为水的比热容，且c 0＝4.2×10 3J/(㎏·℃)，ξ为与衣物材质相关的修正系数。
优选地，衣物处理设备预存衣物的材质信息与修正系数ξ的取值的对应关系。衣物处理设备获取待洗衣物的材质信息，根据材质信息与ξ的对应关系调取相应的修正系数ξ的取值，用于计算加热时间t。
在上述方案中，洗涤水中衣物的材质会对洗涤水的比热容造成影响，通过引入修正系数ξ对纯水的比热容c 0进行修正得到洗涤水的比热容，也即加热公式中的加热系数k，用于计算加热时间t，可以得到更加符合实际情况的加热时间t，进而对洗涤水被加热的温度控制更加准确。
待洗衣物的材质信息，例如棉麻、羊毛或羽绒等由用户在设置洗衣程序时手动输入，或者衣物处理设备根据用户选择的洗衣程序类型对应出待洗衣物的材质信息，进而通过材质信息与ξ的对应关系调取相应的修正系数ξ的取值，用于计算洗涤水的比热容，得到加热公式中的加热系数k，进而可计算得到加热时间t。
本实施例的进一步方案中，温度检测装置在加热装置的加热过程中间歇或持续检测内筒与外筒之间的温度，获取加热装置启动后不同时间节点下的实时温度T’。
具体地，本实施例中，温度检测装置在加热装置的加热过程中间歇进行温度检测操作， 根据检测到的实时温度T’以及加热装置执行加热操作的持续时间t 1计算升温速率v。
衣物处理设备具有预设的升温速率取值范围，当计算得到的升温速率v超出所述升温速率取值范围时，判定出现加热故障。
优选地，衣物处理设备预存升温速率取值范围与目标加热温度T的取值的对应关系，获取目标加热温度后，根据升温速率取值范围与T的对应关系调取相应的升温速率取值范围，用于与计算得到的升温速率v进行比较。
在上述方案中，对于不同的目标加热温度T，预先通过大量的实验测试得出加热过程中，内筒与外筒之间温度在正常情况下的升温速率取值范围。加热装置启动后，温度检测装置在特定的时间节点进行温度检测操作，并根据检测结果计算当前的升温速率v，若升温速率v超出所述升温速率取值范围，说明加热过程出现异常。尤其是升温速率v大于升温速率取值范围的上限时，说明升温过快，很可能出现了进水不足或无水加热的情况，立即停止加热以免造成安全事故。
例如，用户设定的目标加热温度T为60℃，在获取进水量m和进水温度T 1后计算得到的加热时间t为50min，根据升温速率取值范围与T的对应关系调取相应的升温速率取值范围为0.8±0.2℃/min。
加热过程中，控制温度检测装置在加热装置启动后的10min，20min，30min和40min分别进行温度检测操作并计算升温速率v，若升温速率v满足所述升温速率取值范围，例如v＝1.0℃/min，说明加热过程正常，可继续加热直至加热装置启动后50min停止加热。若任意一次计算得到的升温速率v超出所述升温速率取值范围，例如v＝1.1℃/min，说明升温过快，很可能出现了进水不足或无水加热的情况，立即控制加热装置停止加热。
例如，用户设定的目标加热温度T为90℃，在获取进水量m和进水温度T 1后计算得到的加热时间t为140min，根据升温速率取值范围与T的对应关系调取相应的升温速率取值范围为0.5±0.2℃/min。
加热过程中，控制温度检测装置在加热装置启动后的20min，40min，60min，80min，100min和120min分别进行温度检测操作并计算升温速率v，若升温速率v满足所述升温速率取值范围，例如v＝0.7℃/min，说明加热过程正常，可继续加热直至加热装置启动后140min停止加热。若任意一次计算得到的升温速率v超出所述升温速率取值范围，例如v＝0.8℃/min，说明升温过快，很可能出现了进水不足或无水加热的情况，立即控制加热装置停止加热。
本实施例中，衣物处理设备根据用户设定的目标加热温度T计算出所需的加热时间t，以控制洗涤水的加热过程。在加热过程中的一个或多个时间节点对内、外筒之间的实时温度T’进行检测，并计算出升温速率v，与预设的升温速率取值范围进行比较。若升温速率v超出所述升温速率取值范围，判定发生了加热故障，控制加热装置停止加热，可以在衣物处理设备出现加热故障时及时做出响应，提高了加热安全性。若升温速率v一直满足所述升温速率取值范围，在加热装置的持续加热时间达到计算的加热时间t时，结束加热过程，可以更加准确地控制洗涤水达到目标加热温度T。
实施例二
如图4所示，本实施例与上述实施例一的区别在于：所述的温度检测装置在加热装置的加热过程中持续进行温度检测操作，当检测到的实时温度T’与预设温度T 0’一致时，获取当前时间节点下加热装置的持续加热时间t 2。
衣物处理设备预设有达到预设温度T 0’所需的持续加热时间取值范围，若当前的持续加热时间t 2超出所述持续加热时间取值范围时，判定出现加热故障。
优选地，衣物处理设备预存持续加热时间取值范围与目标加热温度T的取值的对应关系，获取目标加热温度T后，根据持续加热时间取值范围与T的对应关系调取相应的持续加热时间取值范围，用于与持续加热时间t 2进行比较。
在上述方案中，对于不同的目标加热温度T，预先通过大量的实验测试得出加热过程中，内筒与外筒之间温度在正常情况下达到特定的预设温度T 0’所需的持续加热时间取值范围。加热装置启动后，温度检测装置持续进行温度检测操作，在实时温度T’达到预设温度T 0’时获取当前的持续加热时间t 2，若持续加热时间t 2超出所述持续加热时间取值范围，说明加热过程出现异常。尤其是持续加热时间t 2小于持续加热时间取值范围的下限时，说明加热过快，很可能出现了进水不足或无水加热的情况，立即停止加热以免造成安全事故。
本实施例的进一步方案中，衣物处理设备预存预设温度T 0’的取值与目标加热温度T的取值的对应关系。获取目标加热温度T后，根据T 0’与T的对应关系调取相应的预设温度T 0’的取值，用于在加热过程中获取对应的持续加热时间t 2。
在上述方案中，预设温度T 0’的取值为正常情况下，加热至所需的目标加热温度T过程中，内、外筒之间所能达到的最高温度，也即，不同的目标加热温度T对应有不同的预设温度T 0’取值。由于不同目标加热温度T下内、外筒之间的温度变化过程不同，分别采用不同的预设 温度T 0’取值进行加热故障的判断，对加热故障的判定更加及时准确。预先通过大量的实验测试得出T 0’与T的对应关系，在衣物处理设备运行加热程序时直接调用，控制逻辑简单，易于实现。
例如，用户设定的目标加热温度T为30℃，在获取进水量m和进水温度T 1后计算得到的加热时间t为10min，根据持续加热时间取值范围与T的对应关系调取相应的持续加热时间取值范围为10±5min。
加热过程中，控制温度检测装置持续进行温度检测操作，当检测到得到实时温度T’达到30℃下的预设温度T 0’时，获取当前的持续加热时间t 2，若持续加热时间t 2满足所述持续加热时间取值范围，例如t 2＝9min，说明加热过程正常，可继续加热直至加热装置启动后10min停止加热。若持续加热时间t 2超出所述升温速率取值范围，例如t 2＝2min，说明升温过快，很可能出现了进水不足或无水加热的情况，立即控制加热装置停止加热。
例如，用户设定的目标加热温度T为50℃，在获取进水量m和进水温度T 1后计算得到的加热时间t为30min，根据持续加热时间取值范围与T的对应关系调取相应的持续加热时间取值范围为30±15min。
加热过程中，控制温度检测装置持续进行温度检测操作，当检测到得到实时温度T’达到50℃下的预设温度T 0’时，获取当前的持续加热时间t 2，若持续加热时间t 2满足所述持续加热时间取值范围，例如t 2＝25min，说明加热过程正常，可继续加热直至加热装置启动后30min停止加热。若持续加热时间t 2超出所述升温速率取值范围，例如t 2＝14min，说明升温过快，很可能出现了进水不足或无水加热的情况，立即控制加热装置停止加热。
本实施例中，温度检测装置在加热过程中持续对内、外筒之间的实时温度T’进行检测，在实时温度T’达到预设温度T 0’时获取当前的持续加热时间t 2，与预设的持续加热时间取值范围进行比较。若持续加热时间t 2超出所述持续加热时间取值范围，判定发生了加热故障，控制加热装置停止加热，可以在衣物处理设备出现加热故障时及时做出响应，提高了加热安全性。若持续加热时间t 2满足所述持续加热时间取值范围，在加热装置的持续加热时间达到计算的加热时间t时，结束加热过程，可以准确地控制洗涤水达到目标加热温度T。
实施例三
如图5所示，本实施例为上述实施例一或二的进一步限定，所述的衣物处理设备获取目标加热温度T后，与预设目标温度T 0进行比较。
若T>T 0，加热装置启动后，温度检测装置间歇进行温度检测操作，根据检测到的实时温度T’以及加热装置执行加热操作的持续时间t 1计算升温速率v，并根据升温速率v判断是否出现加热故障；
若T≤T 0，温度检测装置在加热装置的加热过程中持续进行温度检测操作，获取实时温度T’达到预设温度T 0’时的持续加热时间t 2，并根据持续加热时间t 2判断是否出现加热故障。
具体地，当用户设定的目标加热温度T大于预设目标温度T 0，也即目标加热温度T较高时，对应的加热时间t也相应较长。此时衣物处理设备采用温度检测装置间歇进行温度检测操作，计算出升温速率v以判断是否出现加热故障的方式控制加热过程。具体的控制过程与实施例一中相同。
当用户设定的目标加热温度T小于等于预设目标温度T 0，也即目标加热温度T较低时，对应的加热时间t也相应较短。此时衣物处理设备采用温度检测装置持续进行温度检测操作，根据实时温度T’达到预设温度T 0’所需的持续加热时间t 2判断是否出现加热故障的方式控制加热过程。具体的控制过程与实施例二中相同。
在上述方案中，当目标加热当目标加热温度T较高时，所需的加热时间t较长，采用升温速率v进行判断的方式可以避免温度检测装置长时间持续工作，进而避免了温度检测装置产时间持续工作造成的测量准确度下降的问题，可以延长其使用寿命。当目标加热温度T较低时，所需的加热时间t较短，若采用升温速率v进行判断的方式，两次温度检测操作之间的时间间隔较短，同时，升温速率出现异常时，其变化的幅度也相对较小，可能造成衣物处理设备的误判，而采用持续加热时间t 2进行判断的方式更容易实现，而且判断更加准确，可以及时发现加热故障。
本实施例中，衣物处理设备在获取目标加热温度后，可以根据目标加热温度T的取值自动选择采用升温速率v或持续加热时间t 2用于判断是否出现加热故障，从而实现对加热故障更准确的判断，并保护温度检测装置，延长其使用寿命，智能化程度高。
实施例四
本实施例提供一种衣物处理设备及其控制方法，所述衣物处理设备具有干衣功能，所述控制方法具体用于衣物处理设备运行干衣程序时的加热过程。
本实施例中，所述衣物处理设备包括放置衣物的衣物处理筒，以及向衣物处理筒中通入高温空气的风道。衣物处理设备还包括温度检测装置，其可安装于衣物处理筒的内部或外部， 从而检测周围的环境温度，根据检测结果控制干衣过程中的烘干温度。
但由于温度检测装置获取的仅为周围一定区域的环境温度，无法获取待烘干衣物所处环境的整体温度准确值，进而对烘干温度的准确性控制较差。为此，本实施例提供了一种衣物处理设备的控制方法，包括：
衣物处理设备获取衣物处理筒中的衣物量m，初始状态下所述衣物处理筒的内部/外周的温度T 1，以及目标加热温度T；
根据所述衣物量m，初始状态下衣物处理筒的内部/外周的温度T 1，以及目标加热温度T计算出达到所述目标加热温度T所需的加热时间t；
控制加热装置启动执行加热操作；
在达到加热时间t之前，控制温度检测装置进行至少一次温度检测操作，根据温度检测装置检测得到的实时温度T’判断是否出现加热故障。
在上述方案中，目标加热温度T由衣物处理设备接收用户的设置信息获取，衣物量m可由衣物处理设备内部的重量传感器获取，温度检测装置在干衣程序启动时即进行一次温度检测操作，从而获取初始状态下衣物处理筒的内部/外周的温度T 1。
在加热过程中，温度检测装置在加热装置的加热过程中间歇或持续检测衣物处理筒的内部/外周的温度，获取加热装置启动后不同时间节点下的实时温度T’。若判定出现加热故障，则控制加热装置停止加热，衣物处理设备发出报警信号。否则，当加热装置执行加热操作的持续时间达到加热时间t时，控制加热装置结束加热操作。
本实施例中，衣物处理筒在干衣程序运行过程中转动，温度检测装置固定安装在衣物处理设备内部，位于衣物处理筒外部，此时温度检测装置检测的初始温度T 1，以及实时温度T’均为衣物处理筒外周的温度。
本实施例的具体方案中，衣物处理设备根据加热公式P*Φ*t＝k*m*(T-T 1)计算得到加热时间t。其中，P为加热装置的加热功率，k为与被加热物质相关的加热系数，本实施例中k的具体取值与待烘干的衣物材质有关，Φ为加热装置将电能转化为热能的效率，且Φ<1。也即，加热时间t＝k*m*(T-T 1)/(P*Φ)。
衣物处理设备预存衣物的材质信息与加热系数k的取值的对应关系。衣物处理设备获取待烘干衣物的材质信息，根据材质信息与k的对应关系调取相应的加热系数k的取值，用于计算加热时间t。
待烘干衣物的材质信息，例如棉麻、羊毛或羽绒等由用户在设置干衣程序时手动输入，或者由衣物处理设备设置的识别装置对衣物进行识别，进而通过得到的材质信息与k的对应关系调取相应的加热系数k的取值，用于计算得到加热时间t。
本实施例中，衣物处理设备根据温度检测装置获取的实时温度T’判断是否发生加热故障的具体方法可采用实施例一至三中任意一项的控制方法，在此不再赘述。
本实施例的衣物处理设备及控制方法可以在衣物处理设备运行干衣程序时，对其加热过程进行控制，根据用户设定的目标加热温度T计算出所需的加热时间t，在通过温度检测装置间歇或持续进行温度检测，判断是否出现加热故障。在加热故障发生时，可以及时作出响应，控制加热装置停止加热，避免安全事故的发生。若未发生加热故障，加热装置持续工作直至达到加热时间t后，结束加热过程，可以更准确的控制烘干温度达到目标加热温度T。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
