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。
本公开实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开实施例的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
除非另有说明，术语“多个”表示两个或两个以上。
本公开实施例中，字符“/”表示前后对象是一种“或”的关系。例如，A/B表示：A或B。
术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
结合图1所示，本公开实施例提供一种用于控制空调器的方法，包括：
S10、控制空调器运行空气调节模式并获取空调器的冷媒循环状态；
S20、在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长；
S30、重复以上操作预设次数后，在空调器仍然存在冷媒循环异常的情况下，确定空调器发生冷媒泄漏。
本公开实施例可以提供一种多次获取冷媒循环状态并控制空调器相关部件运行的方法，以避免对空调器冷媒泄漏造成误判。具体地，可以控制空调器运行空气调节模式并获取空调器的冷媒循环状态，在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长；重复以上操作预设次数后，在空调器仍然存在冷媒循环异常的情况下，确定空调器发生冷媒泄漏。
本公开实施例采用预设次数重复执行空调器冷媒循环状态的获取，以及在冷媒循环状态为冷媒循环异常的情况下，控制压缩机停机以及内风机持续运转达第一预设时长，若空调器仍然存在冷媒循环异常的现象，则确定空调器发生冷媒泄漏。这样一方面能够避免压缩机过热造成损坏，另一方面通过重复执行该过程达到预设次数，能够降低对冷媒泄漏的误判率，较为准确地判断出空调器是否出现了冷媒泄漏。这样，能够避免空调器进行不必要的停机，避免影响用户体验。
冷媒循环异常，例如，冷媒管路中的冷媒存在流量过大或过小的现象。当检测出空调器存在冷媒循环异常的情况时，未必就是发生了冷媒泄漏，引起冷媒循环异常的原因可能是局部管路发生堵塞，也可能是冷媒管路发生泄漏，还有可能是其它情况。有些程度较轻的堵塞，无需空调器停机也可能实现疏通，则不属于冷媒泄漏的情况，如果将 其认定为冷媒泄漏而控制空调器停机，不仅影响用户体验，后续还会浪费不必要的人力物力来维修。
在发生冷媒泄漏的时候，会造成压缩机过热运行，控制压缩机停机，能够避免压缩机过热运行造成损坏，对压缩机进行保护。控制室内风机保持运转达到第一预设时长，能够使空调器内部温度恢复到室内温度，这样就可以保证每次获取冷媒循环状态时，冷媒循环的初始状态保持一致，防止因为上次检测时空调运转使内部温度，冷媒循环初始状态不一致降低造成误判，增加每次检测的准确性。
作为一种示例，可以通过检测内盘管温度确定空调器的冷媒循环状态。如果在空调上电后，进行温度控制时，内盘管温度在一定时间内变化幅度过小，则表明冷媒循环状态出现异常。在空调器出现冷媒循环异常时，控制室内风机保持运转达到第一预设时长，能够使内盘管温度恢复到室内温度，这样就可以保证每次获取内盘管温度时，内盘管的初始温度保持一致，防止因为上次检测时空调运转使内盘管温度改变，内盘管初始温度不一致降低造成误判，增加每次检测的准确性。
需要说明的是，获取空调器的冷媒循环状态时，是在空调器运行空气调节模式时进行，例如空调器运行制冷/制热时，冷媒在循环流动，这样来获取冷媒循环状态。
可选地，第一预设时长可以为8min、9min，10min或12min等。例如，第一预设时长为10min，在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到10min。
作为一种示例，可以通过设置与压缩机和室内风机连接的控制器，控制压缩机停机且控制室内风机保持运转达到第一预设时长。
作为一种示例，可以在空调器内设置计时电路，使计时电路与室内风机连接，通过计时电路检测室内风机运转时间，以使控制器能够控制室内风机保持运转达到第一预设时长。
“以上操作”是指获取空调器的冷媒循环状态；在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长。
重复以上操作预设次数后，是指重复执行“获取空调器的冷媒循环状态；在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长”达到预设次数。例如，重复执行以上操作两次，即，在执行完“获取空调器的冷媒循环状态；在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长”之后，再执行上述操作 两次，一共执行了上述操作三次。
本公开实施例重复以上操作预设次数，然后如果空调器仍然存在冷媒循环异常的情况，则可以认定空调器发生冷媒泄漏，这样能够充分确认空调器确实发生了冷媒泄漏。冷媒循环异常可能并非是冷媒泄漏引起，如果只是发生了程度较轻的管道堵塞，那么在控制压缩机停机和重新启动后，可能堵塞处已经被冲开，冷媒循环异常的故障得到解除，则不必停机；如果确实存在冷媒泄漏，那么通过重复预设次数，能够充分确认该冷媒循环异常是由冷媒泄漏引起，从而停机。
可选地，预设次数为2次。这样，在重复执行获取冷媒循环状态以及控制相应部件运作两次以后，如果空调器仍然存在冷媒循环异常，则确定空调器发生冷媒泄漏。
在一些实施例中，确定空调器冷媒循环异常之后，还包括：控制空调室外机进行警示。通过警示告知用户存在冷媒循环异常的现象。
作为一种示例，可以通过控制空调室外机的信号灯闪烁进行警示。例如，控制空调室外机的信号灯闪烁28次。
在一些实施例中，确定空调器发生冷媒泄漏之后，还包括：控制空调器的显示面板显示冷媒循环异常故障。通过空调器的显示面板告知用户空调器冷媒循环异常，此处冷媒循环异常故障对应冷媒泄漏的情况，为便于用户理解，可采用“冷媒循环异常故障”来描述该故障。
在一些实施例中，获取空调器的冷媒循环状态，包括：
检测空调器的冷媒流量；
在检测的冷媒流量超过预设流量范围的情况下，确定空调器存在冷媒循环异常现象。
冷媒流量能够反映空调器的冷媒循环状态，在冷媒循环正常的时候，对应冷媒流量的正常范围值，将该正常范围值作为预设流量范围，在检测的冷媒流量超过预设流量范围的情况下，表明冷媒流量不正常，空调器存在冷媒循环异常现象。采用冷媒流量衡量冷媒循环状态较为贴切。
作为一种示例，可以通过在空调器的冷媒管路上设置流量传感器来获取空调器的冷媒循环状态。预设流量范围可以按照现有的空调器冷媒流量进行设定。
需要说明的是，在实际应用过程中，预设流量范围可以结合空调器自身冷媒流量的正常范围进行的取值，在其范围内确定预设流量范围的边界值，并使其满足上述要求。
在一些实施例中，控制空调器运行空气调节模式包括：控制空调器的室内风机以 高风速、中风速或低风速运行空气调节模式。控制室内风机以高风速、中风速或低风速运行空气调节模式均能够检测器冷媒循环状态。
在一些实施例中，控制空调器的室内风机以高风速、中风速或低风速运行空气调节模式，包括：
在空调器首次运行空气调节模式的情况下，控制空调器的室内风机以高风速运行；
在空调器非首次运行空气调节模式的情况下，控制空调器的室内风机以中风速或低风速运行。
首次运行空气调节模式时，空调器可以采用高风速进行空气调节，以期望空调器内部状态能够产生较大的波动，如存在冷媒循环异常，则检测结果较为明显。例如，空调器以高风速进行空气调节，内盘管温度应快速下降，与室外温度产生较大的温差，若检测到内盘管温度变化过小，则可以较准确地确定存在冷媒循环异常。
在非首次运行空气调节模式时，为了进一步验证是否存在冷媒循环异常，采用与高风速不同的风速进行空气调节，例如以中风速或低风速进行调节，以检测是否还出现冷媒循环异常。
作为一种示例，在空调器非首次运行空气调节模式的情况下，控制空调器的室内风机以中风速或低风速运行，包括：
第二次运行空气调节模式时，控制空调器的室内风机以中风速运行；
第三次运行空气调节模式时，控制空调器的室内风机以低风速运行。
第二次室内风机以中风速运行，第三次室内风机以低风速运行，通过风速的区分，能够不断验证是否确实存在冷媒异常，从而最终确定存在冷媒泄漏的情况。第三次采用低风速运行空气调节模式，空调器内部状态波动较小，如果在该状态下，仍然能够确定存在冷媒循环异常，则对于冷媒泄漏的确定更加准确。本公开实施例通过进行多种风量下的检测可以提高检测准确性，防止造成误判。
需要说明的是，不同的空调器可能对应有不同的风速档位，在实际使用过程中，可以结合空调器自身风速档位的取值范围来确定高风速、中风速和低风速的范围，在高风速、中风速和低风速的范围内确定高风速、中风速和低风速的具体数值，并使其满足上述要求。
在一些实施例中，室内风机保持运转包括：室内风机保持低风速或中风速运转。
本公开实施例通过控制室内风机保持低风速或中风速运转，能够使空调器内部温度恢复到室内温度，保证每次获取冷媒循环状态时，冷媒循环的初始状态保持一致，增 加每次检测的准确性。室内风机保持低风速或中风速运转，能够避免该过程的能耗过大。
在一些实施例中，确定空调器发生冷媒泄漏之后，还包括：控制压缩机停机，且室内风机保持运转达到第二预设时长后停止。
本公开实施例在确定空调器发生冷媒泄漏之后，通过控制压缩机停机来防止压缩机过热损毁，通过控制室内风机保持运转达到第二预设时长后停止，使空调器内部恢复至室内温度。
作为一种示例，第二预设时长可以是30s、35s、40s、45s等。例如，第二预设时长为30s。
作为一种示例，控制压缩机停机，且室内风机保持运转达到第二预设时长后停止，且控制空调器显示面板显示冷媒循环异常故障。
结合图2所示，示例性地，用于控制空调器的方法，包括：
S10、控制空调器运行空气调节模式并获取空调器的冷媒循环状态；
S20、在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长；
S30、重复以上操作预设次数后，在空调器仍然存在冷媒循环异常的情况下，确定空调器发生冷媒泄漏；
S40、控制压缩机停机，且室内风机保持运转达到第二预设时长后停止。
通过该示例，能够较为准确地确定空调器存在冷媒泄漏现象，并保护压缩机，防止压缩机过热损毁。
在一些实施例中，第二预设时长小于第一预设时长。由于已经确定发生冷媒泄漏，故使室内风机保持运转达到第二预设时长后停止即可，小于第一预设时长，不必运转时间过久，这样能够节省电能。
在一些实施例中，在获取空调器的冷媒循环状态之前，还包括：
获取空调器的上电信息或停机时长信息；
在空调器为首次上电或停机超过第三预设时长的情况下，启动获取空调器的冷媒循环状态的程序。
本公开实施例在空调器为首次上电或停机超过第三预设时长的情况下，启动获取空调器的冷媒循环状态的程序，能够有效监测冷媒循环状态，及时监测出冷媒泄漏的情况。如果空调器为首次上电，存在冷媒泄漏的可能性大于非首次上电，此时，应当对冷媒循环状态进行获取，避免空调器在冷媒泄漏的情况下运行，避免烧毁压缩机。
如果空调器停机超过第三预设时长，则发生冷媒泄漏的可能性也较大，此时，应当对冷媒循环状态进行获取，以及时监测冷媒循环情况，避免空调器在冷媒泄漏的情况下运行。
作为一种示例，第三预设时长可以是1h、1.5h、2h等。例如，第三预设时长为1h。
在一些实施例中，第三预设时长大于第一预设时长。在第三预设时长大于第一预设时长的情况下，表明空调器停机较久，应当进行冷媒泄漏的检测，若发生了冷媒泄漏的情况，能够准确确认，有效避免空调器在冷媒泄漏的情况下运行。
结合图3所示，在一些实施例中，获取空调器的冷媒循环状态，包括：
S11、获取预定时间内空调器的压缩机运行频率以及内盘管温度的变化幅度；
S12、在压缩机运行频率大于或等于预设频率，且变化幅度小于或等于预设幅度的情况下，确定空调器发生冷媒循环异常。
本公开实施例可以提供一种用于控制空调器的方法，以使获取空调器的冷媒循环状态。具体地，可以获取预定时间内空调器的压缩机运行频率以及内盘管温度的变化幅度；在压缩机运行频率大于或等于预设频率，且变化幅度小于或等于预设幅度的情况下，确定空调器发生冷媒循环异常。
本公开实施例确保压缩机运行正常的情况下，通过内盘管温度变化幅度，能够较为准确的获取空调器的冷媒循环状态。
压缩机的运行频率能够反映压缩机的运行状态，通过获取压缩机的运行频率，可以获知压缩机是否正常运行。内盘管温度的变化幅度能够反映冷媒循环状态，通过获取内盘管温度的变化幅度，可以获知冷媒循环状态是否异常。
作为一种示例，可以设置与压缩机连接的振动传感器来检测压缩机的运行频率。
作为一种示例，可以在内盘管设置温度传感器检测内盘管温度。
作为一种示例，预设幅度为1.5℃。内盘管温度的变化幅度如果小于或等于1.5℃，则认为冷媒循环异常。
作为一种示例，预设频率为大于或等于40Hz，或，大于或等于50Hz。
在压缩机运行频率大于或等于预设频率，且变化幅度小于或等于预设幅度的情况下，表明空调器存在冷媒循环异常的现象。因为，在压缩机的运行频率大于或等于预设频率的情况下，表明压缩机正常运行，但内盘管温度的变化幅度却过小，表明冷媒循环异常。
在一些实施例中，在室外温度属于第一区间的情况下，预设频率为第一频率；在 室外温度属于第二区间的情况下，预设频率为第二频率；第二区间的最大值小于第一区间的最小值，第二频率小于第一频率。
在实际处理过程中，可以预先划分表示室外温度大小的区间，例如，划分2个区间，其中，第二区间的最大值小于第一区间的最小值。如果室外温度属于第一区间，则表示室外温度较高。如果室外温度属于第二区间，则表示室外温度中等。
在室外温度较高的情况下，压缩机正常运行时的频率高于室外温度中等情况下的频率，因此，将压缩机的预设频率设为第一频率和第二频率，在室外温度属于第一区间的情况下，预设频率为第一频率；在室外温度属于第二区间的情况下，预设频率为第二频率；第二区间的最大值小于第一区间的最小值，第二频率小于第一频率。这样，能够对冷媒循环异常的判断更加准确。
结合图4所示，示例性地，用于控制空调器的方法，包括：
S11、获取预定时间内空调器的压缩机运行频率以及内盘管温度的变化幅度；
S12、在压缩机运行频率大于或等于预设频率，且变化幅度小于或等于预设幅度的情况下，确定空调器发生冷媒循环异常；
S20、在空调器的冷媒循环状态为冷媒循环异常的情况下，控制空调器的压缩机停机且室内风机保持运转达到第一预设时长；
S30、重复以上操作预设次数后，在空调器仍然存在冷媒循环异常的情况下，确定空调器发生冷媒泄漏。
