本申请涉及空调除霜技术领域，例如涉及一种空调及其除霜的控制方法。
背景技术
随着人们生活水平的提高，空调设备也已经走进了千家万户，家用空调、中央空调的使用越来越普遍，用户对于空调舒适度的要求也越来越高，空调使用过程中所存在的问题也逐渐暴漏出来，其中一个就是空调在严寒气候下运行时的室外机结霜冻结的问题。在空调在低温地区或者风雪较大的地区运行时，室外机的冷凝器外表面所凝结水流会滴落到底盘上，空调器长时间运行情况下，会导致空调器的冷凝器和底盘均出现结冰问题，室外机上凝结的冰层会阻碍内部的冷媒与室外环境的热量交换，使得空调的制冷效率下降，为了保证空调的制热效果，空调不得不提高功率运行，这也导致了电能的额外消耗和用户使用成本的提高。
因此，针对空调的室外机结霜结冰的问题，现有的部分空调配置有除霜功能，例如，利用设置于室外机的加热装置对室外机进行加热，或者，利用制冷模式下压缩机排出的高温冷媒对室外换热器进行化霜融冰。这里，在空调启用除霜功能之前，空调一般是利用室外传感器检测到的外盘管温度与霜点温度结合进行判断是否已经达到了容易凝结冰霜的温度状况，进而判断是否启用除霜功能。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：相关技术中为了避免空调在低温环境下连续频繁的启用除霜功能而影响正常制热工作的问题，一般是设定空调在除霜完成之后的固定时长内不再启动除霜功能，如设定20分钟、30分钟的除霜时间间隔；这种方式存在的弊端就是影响空调室外机结霜程度的因素不仅包括外界环境因素，还包括空调自身状态的影响因素，由于空调每次除霜完成之后自身各部件的工作状态也会发生变化，如果仍以该种固定的除霜时间间隔的方式控制空调是否启用除霜功能，则实际上会与空调实际的结霜状态存在较大的误差，如在极度严寒天气状况下，如果除霜时间间隔设定较长时间，那么空调在除霜时间间隔的时间段内就容易凝结较多的冰霜，而此时空调由于除霜时间间隔的限制则不会立即启用除霜功能，因而就会影响到空调的正常使用。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
图1是本公开实施例提供的空调除霜的控制方法的流程示意图。
如图1所示，本公开实施例提供了一种空调除霜的控制方法，包括：
S101、在空调执行除霜流程完成的情况下，获取空调已执行的除霜流程的除霜时长；
在本公开实施例中，对除霜间隔时长进行修正的操作是在空调已经完成某一次除霜流程之后进行。
这里，空调在完成一次除霜流程之后，该次除霜流程所占用的除霜时长也是可以确定的；这样，在本公开实施例中，空调即是在空调完成某一次除霜流程之后，通过空调该次除霜流程的除霜时长对除霜间隔时长进行修正，修正后的除霜间隔时长是用于下一次待执行的除霜流程的除霜判断。
可选的，本公开实施例中的空调设置有计时模块，计时模块可用于统计空调每次执行的除霜流程的除霜时长，即在空调执行除霜流程的初始时刻开始计时并在完成时刻结束计时，则初始时刻至完成时刻之间的时间即为本次除霜流程的除霜时长；并且，空调的计时模块所统计的除霜时长作为历史运行数据进行保存。
S102、基于空调已执行的除霜流程的除霜时长，对本次除霜流程至下一次除霜流程之间的除霜间隔时长进行修正；
在一些可选的实施例中，被修正的除霜间隔时长为空调预存的一个或一个以上不同时长数值的设定时长值，如2分钟，7分钟，等等；步骤S102中，空调基于除霜流程的除 霜时长对其选定的设定时长值进行修正的操作；
在另一些可选的实施例中，被修正的除霜间隔时长为空调执行的除霜流程与其前一次除霜流程之间的除霜间隔时长；因此，在本公开实施例中，在执行步骤S102之前，本公开实施例的控制方法的步骤还包括：获取空调执行的除霜流程与其前一次除霜流程之间的除霜间隔时长，并将除霜间隔时长作为待修正的除霜间隔时长。
这里，空调设置有计时模块，计时模块可用于统计空调已执行的除霜流程的完成时刻与当前时刻的间隔时长；在上述实施例中，待修正的除霜间隔时长为相邻的两次的除霜流程之间的间隔时长，即前一除霜流程的完成时刻与本次除霜流程的开始时刻之间的时长。
S103、在基于修正后的除霜间隔时长确定满足间隔时长条件的情况下，控制空调进行是否触发下一次除霜流程的除霜判断。
在本公开实施例中，间隔时长条件包括空调已执行的除霜流程的完成时刻与当前时刻的间隔时长大于或等于修正后的除霜间隔时长。因此，若空调满足该间隔时长条件，则控制空调进行是否触发下一次除霜流程的除霜判断；若空调不满足该间隔时长条件，则控制空调不进行是否触发下一次除霜流程的除霜判断。
这里，不同于相关技术中采用固定的除霜间隔时长的控制方式，本公开实施例利用空调执行除霜流程的除霜时长对本次所述除霜流程至下一次除霜流程之间的除霜间隔时长进行修正；则能够在前一次除霜时间较长、除霜效果较好的情况下，延长相连的两次除霜流程之间的时间间隔，以避免对空调在制热工况下的正常制热工作的干扰；而在前一次除霜时间较短、除霜效果较差的情况下，缩短相邻的两次除霜流程之间的时间间隔，以避免室外机中的冰霜凝结过多而降低空调制热效率的问题。
本公开实施例提供的空调除霜的控制方法能够利用空调执行除霜流程的除霜时长对本次所述除霜流程至下一次除霜流程之间的除霜间隔时长进行修正，从而可以降低现有技术中因利用固定的除霜时间间隔的方式控制空调是否启用除霜功能所导致空调除霜功能启用受限、不能及时触发除霜功能的问题，实现了对空调除霜功能更加精准的控制。
在一些可选的实施例中，步骤S103中的控制空调进行是否触发下一次除霜流程的除霜判断的具体执行过程包括：在空调满足预设的除霜条件的情况下，判定空调触发下一次除霜流程；在空调不满足预设的除霜条件的情况下，判定空调不触发下一次除霜流程。
可选的，预设的除霜条件包括空调的室外盘管温度小于霜点温度。
这里，为控制空调进行是否触发下一次除霜流程的除霜判断，本公开实施例的步骤还包括：获取空调的室外盘管温度；将室外盘管温度与霜点温度进行比较，在室外盘管温度小于霜点温度的情况下，判定空调触发下一次除霜流程；在外盘管温度大于或等于霜点温度的情况下，判定空调不触发下一次除霜流程。
在本公开实施例中，空调的室外机另设有一温度传感器，该温度传感器可用于检测室外机的盘管的实时的室外盘管温度；因此，上述步骤即是获取该温度传感器所检测到的室外盘管温度；
示例性的，设定的霜点温度为-1℃；当从温度传感器获取得到的室外盘管温度为-2℃时，-2℃<-1℃，则判定空调触发下一次除霜流程；而当从温度传感器获取得到的室外盘管温度为3℃时，-1℃<3℃，则判定空调触发下一次除霜流程。
这里，本申请控制方法的流程步骤还包括：获取空调在本次开机启动之后除霜流程的执行次数；在除霜流程的执行次数等于0的情况下，基于室外盘管温度和霜点温度控制空调进行是否触发下一次除霜流程的除霜判断；在除霜流程的执行次数不等于0的情况下，则执行步骤S101至S103的控制流程。
空调在开机启动之后对除霜流程的执行次数进行计数操作，计数的初始值为0；空调每执行一次除霜流程，则计数加1；因此，在空调本次开机启动之后、首次执行除霜流程之前，空调对除霜流程的计数为0，此时则基于室外盘管温度和霜点温度控制空调进行是否触发下一次除霜流程的除霜判断。
在空调本次运行结束关机时，空调将除霜流程的计数清零。
图2是本公开又一实施例提供的空调除霜的控制方法的流程示意图。
如图2所示，本公开实施例提供了一种空调除霜的控制方法，该控制方法所限定的流程是在空调已经完成某一次除霜流程之后进行；具体包括：
S201、获取空调已执行的除霜流程的除霜时长；
S202、基于除霜时长和预设的第一关联关系，匹配得到除霜时长对应的时长修正值；
在本公开实施例中，第一关联关系配置为表征一个或一个以上除霜时长与时长修正值的对应关系；预设的第一关联关系中，当除霜时长小于或等于第一时长时，时长修正值为正值；当除霜时长大于第一时长且小于或等于第二时长时，时长修正值为零；当除霜时长大于第二时长时，时长修正值为负值。
示例性的，表1中示出了一种可选的除霜时长与时长修正值的对应关系。
除霜时长(单位：分钟) 时长修正值(单位：分钟)
t<3 5
3≤t<5 0
5<t -5
表1
表1中，第一时长为3分钟，除霜时长小于或等于3分钟时对应的时长修正值为5分钟；第二时长为5分钟，除霜时长大于3分钟且小于或等于5分钟时对应的时长修正值为0分钟；除霜时长大于或等于5分钟时其对应的时长修正值为-5分钟，等；因此在步骤S202中，空调通过该表格可以查找匹配出对应除霜时长的时长修正值。
该关联关系为空调出厂前通过实验等方式计算确定的数值，并预存在空调的电脑板、处理器等控制装置中。
S203、基于匹配得到的时长修正值对待修正的除霜间隔时长进行修正；
在本公开实施例中，步骤S203中计算待修正的除霜间隔时长和时长修正值之和，得到修正后的除霜间隔时长。
S204、获取空调已执行的除霜流程的完成时刻与当前时刻的间隔时长；
S205、判断修正后的除霜间隔时长是否满足间隔时长条件，若是，则执行步骤S206；若否，则返回步骤S204；
S206、控制空调进行是否触发下一次除霜流程的除霜判断。
在本公开实施例中，步骤S206的具体执行过程可以参照前文中的实施例，在此不作赘述。
本公开实施例中所公开的提供的空调除霜的控制方法通过预设的关联关系查找匹配对应空调执行除霜流程的除霜时长的时长修正值，进而根据时长修正值对除霜间隔时长进行修正，能够精确的调整与当前工况相适配的相邻的除霜流程的时间间隔，使得空调更加精确的触发空调的除霜流程。
图3是本公开又一实施例提供的空调除霜的控制方法的流程示意图。
如图3所示，本公开实施例提供了一种空调除霜的控制方法，该控制方法所限定的流程是在空调已经完成某一次除霜流程之后进行；具体包括：
S301、获取空调本次开机的制热模式的累计运行时长；
在本公开实施例中，在空调本次开机之后开始计时，累计运行时长为当前时刻的与空调开机的时刻之间的制热模式的总时长；
例如，空调本次开机的时刻为6:00，空调执行步骤S301的时刻为8:10，其中，6:00至6:30为制热运行状态，6:30至6:50为待机状态，6:50至7:30为制热运行状态，7:30至7:35为除霜流程所限定的除霜状态，7:35至8:00为制热运行状态，8:00至8:02为除霜状态，8:02至8:10为制热运行状态，则可以获取的空调本次开机的制热状态的运行时段包括6:00至6:30的30分钟、6:50至7:30的40分钟、7:35至8:00的25分钟以及8:02至8:10的8分钟，相加之和得到的103分钟即为制热模式的累计运行时长。
在本公开实施例中，本申请结合制热的累计运行时长和除霜时长共同对除霜间隔时长进行修正。
S302、获取空调已执行的除霜流程的除霜时长；
步骤S302中获取的为距离当前最近的一次除霜流程的除霜时长，如结合步骤S301示出的本公开实施例中8:00至8:02的时间段的8分钟；
S303、基于时长组合和预设的第二关联关系，匹配得到时长组合对应的时长修正值；
在本公开实施例中，第二关联关系配置为表征一个或一个以上时长组合与时长修正值的对应关系；时长组合至少包括除霜时长和制热模式的累计运行时长各自所处的时长区间。
示例性的，表2中示出是一个可选的时长组合与时长修正值的对应关系。
时长组合(单位：分钟) 温度修正值(单位：℃)
t<3且T<T1 5
3<t≤5且T<T1 0
5<t≤9且T>T1 -1
表2
其中，t为除霜时长，T为制热模式的累计运行时长。在步骤S304中，空调通过该表格可以查找匹配出对应时长组合的时长修正值。
该关联关系为空调出厂前通过实验等方式计算确定的数值，并预存在空调的电脑板、处理器等控制装置中。
S304、基于匹配得到的时长修正值对待修正的除霜间隔时长进行修正；
在本公开实施例中，步骤S307中计算待修正的除霜间隔时长和时长修正值之和，得到修正后的除霜间隔时长。
S305、获取空调已执行的除霜流程的完成时刻与当前时刻的间隔时长；
S306、判断修正后的除霜间隔时长是否满足间隔时长条件，若是，则执行步骤S307；若否，则返回步骤S305；
S307、控制空调进行是否触发下一次除霜流程的除霜判断。
在本公开实施例中，步骤S307的具体执行过程可以参照前文中的实施例，在此不作赘述。
本公开实施例中所公开的提供的空调除霜的控制方法通过预设的关联关系查找匹配对应时长组合的时长修正值，进而根据时长修正值对除霜间隔时长进行修正，这里，时长组合可以同时反映空调本次开机运行之后制热模式和最近一次的除霜流程这两个不同流程所占用的时长，由于空调以制热模式运行室外机吸收热量，因此也会影响到结霜程度，这样，将最近一次的除霜流程的除霜时长与制热模式的累计运行时长综合进行考虑，使其能够更容易触发下一次除霜流程，这样，使得空调更加精确的触发适配当前工况的除霜流程。
