 有益效果
与现有技术相比，本申请实施例提供的除湿机的无霜运行方法，操作时，首先可利用温度监测模组感知监测除湿机主体内的蒸发器表面的温度变化，当蒸发器的表面温度小于或等于零下1℃时，蒸发器的表面便会发生结霜倾向或轻微的结霜，此时温度监测模组即可将模组模组传送相应的电信号，而控制模组可根据温度监测模组所回传的电信号驱动调节与蒸发器相连接的可调节流装置运行，使得可调节流装置增大流入蒸发器内的高温制冷剂的流量，如此蒸发器的表面温度便会因为蒸发器内的高温制冷剂的余热而迅速提升，这样便能够及时化除蒸发器表面的轻微结霜并避免了后续运行过程中蒸发器表面结霜现象的发生。如此，根据上述方法运行的除湿机便能够在环境温度为8℃~13℃的低温环境内稳定工作而不发生结霜现象。
本申请实施例提供的除湿机的有益效果在于：本申请的除湿机，由于包括有可调节流装置、控制模组和温度监测模组，那么其在低温环境中工作时，温度监测模组便能够对除湿机内的蒸发器表面的温度进行实时监测，当蒸发器表面的温度低于预设的温度值时，蒸发器的表面发生结霜倾向或轻微结霜时，温度监测模组即可将相应的电信号回传至控制模组，而控制模组则可根据该电信号来驱动调节可调节流装置增大流入蒸发器内的高温制冷剂，进而使得蒸发器的表面温度提升，进而化除蒸发器表面的轻微结霜并使得除湿机在低温环境中运行的过程中，蒸发器的表面避免发生结霜。

实施例一。
如图1所示，本实施例提供的除湿机的无霜运行方法，其用于使得除湿机在低温环境中实现无霜化运行，具体地，除湿机的无霜运行方法包括以下步骤：
S100：提供可调节流装置20，将可调节流装置20安装于除湿机主体10内，并将可调节流装置20连接于除湿机主体10内的蒸发器30上以调节进入蒸发器30内的高温制冷剂的流量；其中，可调节流装置20的高温制冷剂输出端与蒸发器30相连接，可调节流装置20的高温制冷剂输入端与除湿机内的压缩机的高温制冷剂输出端相连接。
S200：提供控制模组40，将控制模组40安装于除湿机主体10内，且将控制模组40与可调节流装置20电连接；
S300：提供温度监测模组50，将温度监测模组50安装于蒸发器30上以监测蒸发器30的表面温度，并将温度监测模组50与控制模组40电连接；
S400：当蒸发器30的表面温度小于或等于零下1℃时，温度监测模组50将该温度信息反馈至控制模组40，控制模组40根据该温度信息驱动调节可调节流装置20增大流入蒸发器30内的高温制冷剂的流量。在实际工况条件下，当环境温度低于10℃（低温环境）时，除湿机的蒸发器30的温度多会落0℃以下，当蒸发器30温度低于零下1℃时，会开始出现结霜现象，而当蒸发器30温度低于零下1℃时，结霜现象尤甚。故本申请将温度监测模组50的温度探测点设置在零下1℃左右。同时，当蒸发器30的表面温度介于0℃和零下1℃之间时，控制模组40还可驱动调节可调节流装置20适度地增大流入蒸发器30内的高温制冷剂的流量。而当蒸发器30的表面温度高于0℃后，则控制模组40无需介入对可调节流装置20的调控，可调节节流装置20可依照预先设定好的流量参数向蒸发器30内正常输入高温制冷剂。
本申请实施例提供的除湿机的无霜运行方法，操作时，首先可利用温度监测模组50感知监测除湿机主体10内的蒸发器30表面的温度变化，当蒸发器30的表面温度小于或等于零下1℃时，蒸发器30的表面便会发生结霜倾向或轻微的结霜，此时温度监测模组50即可将模组模组传送相应的电信号，而控制模组40可根据温度监测模组50所回传的电信号驱动调节与蒸发器30相连接的可调节流装置20运行，使得可调节流装置20增大流入蒸发器30内的高温制冷剂的流量，如此蒸发器30的表面温度便会因为蒸发器30内的高温制冷剂的余热而迅速提升，这样便能够及时化除蒸发器30表面的轻微结霜并避免了后续运行过程中蒸发器30表面结霜现象的发生。如此，根据上述方法运行的除湿机便能够在环境温度为8℃~13℃的低温环境内稳定工作而不发生结霜现象。
进一步地，当温度监测模组50感测到蒸发器30表面温度已处于0℃~零下1℃之间时，即可向控制模组40发出停止信号，控制模组40在收到停止信号后可驱动可调节流装置20将流入蒸发器30内的高温制冷剂的流量回复至正常水平。
在本实施例中，步骤S400还包括以下步骤：
S410：提供延时模组（图未示），将延时模组安装于除湿机主体10内，并将延时模组与控制模组40电连接，通过延时模组控制控制模组40每隔大于或等于30min的时间段对调节可调节流装置20进行一次驱动调节。具体地，由于延时模组的存在，这样其便能够有效避免可调节流装置20过于频繁地进行增大高温制冷剂的操作过程，进而能够有效地保证可调节流装置20的工作寿命。
在本实施例中，如图2所示，可调节流装置20包括第一节流机构（图未示），第一节流机构连接于蒸发器30并与控制模组40电连接。且第一节流机构为电子节流器。具体地，通过将第一节流机构设定为电子节流器，这样便显著提升了节流器的节流精确度，进而便显著提升了进入到蒸发器30内的高温制冷剂的流量的精确度，由此便能够使得蒸发器30的化霜和预防结霜的过程变的更为精确可控。
实施例二。
如图3所示，本实施例与实施例一的区别在于：可调节流装置20包括第二节流机构21，第二节流机构21包括常温节流器211、低温节流器212、第一控制阀213和第二控制阀214，常温节流器211和低温节流器212均连接于蒸发器30上，第一控制阀213与常温节流器211相连接以控制常温节流器211的通断，第二控制阀214与低温节流器212相连接以控制低温节流器212的通断。同时，第一控制阀213和第二控制阀214均为电磁阀，且第一控制阀213和第二控制阀214均与控制模组40电连接；当蒸发器30的表面温度小于或等于零下1℃时，控制模组40控制第一控制阀213关闭常温节流器211，第二控制阀214开启低温节流器212；当蒸发器30的表面温度大于或等于0℃时，控制模组40控制第二控制阀214关闭低温节流器212，第一控制阀213开启常温节流器211。低温节流器212的高温制冷剂的通过流量大于常温节流器211的高温制冷剂的通过流量。如此，由于常温节流器211和低温节流器212的存在，那么当蒸发器30的表面温度小于或等于零下1℃时，控制模组40即可控制低温节流器212运行，而由于低温节流器212的流量大于常温节流器211的流量，其中，常温节流器211可为标准节流器（参照环境温度27℃，60％湿度设计），而低温节流器212可为根据环境温度在8~10℃，80％湿度的参数指标来设计高温制冷剂的通过流量，进而使得在上述环境温度和湿度水平下，低温节流器212即可将足够的高温制冷剂输入于蒸发器30内，从而使得蒸发器30表面形成的霜化除，并使得除湿机在低温环境中运行时，其内的蒸发器30避免结霜。而当蒸发器30的表面温度大于或等于0℃时，控制模组40即可控制常温节流器211运行，从而节省除湿机的运行成本。而根据实际测试结果来看，当除湿机在低温环境中运行时，采用低温节流器212可使得除湿量提升60％，而消耗功率则能够降低10％。
在本实施例中，常温节流器211和低温节流器212均为五金节流器。具体地，通过将常温节流器211和低温节流器212均设定为五金节流器，那么得益于五金节流器支撑成本低的优点，上述的除湿机的无霜运行方法便可应用于一般的家用制冷设备的运行中。
在本实施例中，常温节流器211和低温节流器212并联设置。具体地，通过将常温节流器211和低温节流器212并联设置，这样一方面方便常温节流器211和低温节流器212在除湿机主体10内的装配，另一方面也便于常温节流器211和低温节流器212与第一控制阀213和第二控制阀214的安装连接。
本实施例的其余部分与实施例一相同，在本实施例中未解释的特征，均采用实施例一的解释，这里不再进行赘述。
实施例三。
如图4所示，本实施例与实施例二的区别在于：可调节流装置20还包括第三节流机构22，第三节流机构22包括第一节流器221、第二节流器222和第三控制阀223，第一节流器221和节流器并联设置并均连接于蒸发器30，第三控制阀223安装于第二节流器222上以控制第二节流器222的通断。第三控制阀223与控制模组40电性连接，当蒸发器30的表面温度低于或等于零下1℃时，控制模组40控制第三控制阀223开启第二节流器222；当蒸发器30的表面温度大于或等于0℃时，控制模组40控制第三控制阀223关闭第二节流器222。第二节流器221的高温制冷剂的通过流量大于第一节流器222的高温制冷剂的通过流量。具体地，通过使得第三节流机构22包括第一节流器221、第二节流器222和第三控制阀223，并使得第一节流器221的高温制冷剂的通过流量小于第二节流器222的高温制冷剂的通过流量。那么当蒸发器30的表面温度低于或等于零下1℃时，第一节流器221可维持进入蒸发器30的高温制冷剂的流量不变，而控制模组40此时可控制第三控制阀223开启第二节流器222，进而使得第二节流器222进一步向蒸发器30内输入高温制冷剂，进而使得蒸发器30表面温度上升，化除和防止结霜。
本实施例的其余部分与实施例二相同，在本实施例中未解释的特征，均采用实施例二的解释，这里不再进行赘述。
实施例四。
如图4所示，本实施例与实施例三的区别在于：第一节流器221的高温制冷剂的通过流量等于第二节流器222的高温制冷剂的通过流量。具体地，通过使得第一节流器221和第二节流器222的高温制冷剂的通过流量相同，这样便相当于在蒸发器30的表面温度低于或等于零下1℃时，为蒸发器30输入了双倍流量的高温制冷剂，进而显著提升了蒸发器30的化除结霜的效率，同时也保证了蒸发器30在长期低温环境中运行时，表面不结霜。
实施例五。
如图2所示，本实施例提供了一种除湿机，包括除湿机主体10，除湿机还包括用于向除湿机主体10内的蒸发器30内输入高温制冷剂的可调节流装置20、控制模组40和温度监测模组50，可调节流装置20安装于除湿机主体10内并连接于蒸发器30上，控制模组40安装于除湿机主体10内，可调节流装置20与控制模组40电连接，温度监测模组50安装于蒸发器30上，且温度监测模组50与控制模组40电连接。
本申请实施例提供的除湿机，由于包括有可调节流装置20、控制模组40和温度监测模组50，那么其在低温环境中工作时，温度监测模组50便能够对除湿机内的蒸发器30表面的温度进行实时监测，当蒸发器30表面的温度低于预设的温度值时，蒸发器30的表面发生结霜倾向或轻微结霜时，温度监测模组50即可将相应的电信号回传至控制模组40，而控制模组40则可根据该电信号来驱动调节可调节流装置20增大流入蒸发器30内的高温制冷剂，进而使得蒸发器30的表面温度提升，进而化除蒸发器30表面的轻微结霜并使得除湿机在低温环境中运行的过程中，蒸发器30的表面避免发生结霜。
在本实施例中，除湿机还包括延时模组（图未示），延时模组安装于除湿机主体10内，且延时模组与控制模组40电连接以控制控制模组40驱动调节可调节流装置20的时间间隔。具体地，由于延时模组的存在，这样其便能够有效避免可调节流装置20过于频繁地进行增大高温制冷剂的操作过程，进而能够有效地保证可调节流装置20的工作寿命。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的思想和原则之内所作的任何修改、等同替换或改进等，均应包含在本申请的保护范围之内。
