附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解,这些附图未必是按比例绘制的。附图中:
图1是根据本发明一个实施例的空调器滤网清洗提示方法的示意图;
图2是根据本发明另一个实施例的空调器滤网清洗提示方法的示意图;
图3是根据本发明再一个实施例的空调器滤网清洗提示方法的示意图;
图4是根据本发明又一个实施例的空调器滤网清洗提示方法的示意图;
图5是根据本发明一个实施例的空调器的示意框图。
具体实施方式
本实施例首先提供了一种空调器滤网清洗提示方法,图1是根据本发明 一个实施例的空调器滤网清洗提示方法的示意图。
如图1所示,本实施例的空调器滤网清洗提示方法至少可以包括步骤S102至步骤S108:
步骤S102,获取空调器室内风机在预设档位下的第一电流,以得到第一电流值;
步骤S104,判断第一电流值是否在预设的第一电流阈值范围内,若否,则控制空调器执行自清洁;
步骤S106,在空调器自清洁结束后,控制空调器室内风机按照预设的检测模式运行,并获取空调器室内风机在检测模式下的检测电流;
步骤S108,提取检测电流的特征信息,并根据特征信息判断空调器室内风机是否异常,并在确定异常时,控制空调器发出滤网清洗提示信号,以提示用户进行滤网清洗。
本发明实施例提供了一种空调器滤网清洗提示方法,基于本发明实施例可以实现对运行中空调器室内风机的电流的检测和判断,在检测到预设档位下的第一电流值不在预设的第一电流阈值范围内时,自动控制空调器执行自清洁,使得空调器蒸发器保持干净。并且可以通过对自清洁后空调器室内风机在检测模式下的检测电流的特征信息的判断,实现对引起滤网清洗提示误报的可能性进行排查,进而有效排除了因蒸发器脏和/或蒸发器上有冷凝水等原因导致的空调器室内风机的电流异常引发的滤网清洗提示误报现象,有效减少滤网清洗提示误报现象的发生,提高了滤网清洗提示的准确性,提升了用户的使用体验。
针对上述步骤S102,本发明提供了一种具体实施方式,包括:记录空调器的累计运行时间;在累计运行时间大于等于第一预设时间时,获取空调器室内风机在预设档位下的第一电流值。这里累计运行时间为空调器安装于使用环境首次上电开始至当前时间点结束的时间段内空调器单次运行时间的累加,可以通过计时装置记录空调器的累计运行时间。
实际应用中,由于空调器室内风机的电流还与空调器室内风机所处的空气温度有关,不同空气温度下,空调器室内风机在相同档位下的正常电流范围也会不同,在判断第一电流值是否在预设的第一电流阈值范围内之前,可以建立空气温度和第一电流阈值范围的映射关系,并获取当前空气温度,之后将第一电流值与当前空气温度对应的第一电流阈值范围进行对比,以提高 判断精确性。
步骤S104中提及的控制空调器执行自清洁,可以包括:接收自清洁命令,控制空调器执行制冷模式以使蒸发器结霜;在蒸发器结霜第二预设时间后,控制空调器执行制热模式以对蒸发器进行化霜,以利用化霜水冲洗蒸发器;在蒸发器化霜第三预设时间后,控制空调器执行制热模式以将蒸发器上的化霜水吹干。通过自清洁可以将蒸发器上附着的灰尘冲走,并且可以将蒸发器上残留的化霜水烘干,有助于减少滤网清洗提示误报。
对于上述步骤S106中的控制空调器室内风机按照预设的检测模式运行,并获取空调器室内风机在检测模式下的检测电流,以及上述步骤S108中的提取检测电流的特征信息,并根据特征信息判断空调器室内风机是否异常,本发明提供了两种实施方式。
在一可选实施例中,可以控制空调器室内风机按照预设的第一检测模式运行,其中,第一检测模式可以配置成使空调器室内风机在预设档位下运行,然后获取空调器室内风机在预设档位下的第二电流,进而检测预设档位下的第二电流大小,以得到第二电流值,并判断第二电流值是否在预设的第二电流阈值范围内,若否,则判断空调器室内风机异常。在本可选实施例中,第一检测模式配置成使空调器室内风机在预设档位下运行,也就是说,在自清洁后,空调器室内风机的档位不变,仍保持自清洁前的预设档位,通过预设档位下的第二电流值与第二电流阈值范围的比较来判断空调器室内风机是否异常。基于本可选实施例的方案可以在自清洁后对空调器室内风机在预设档位下的电流进行再次检测,进而将再次检测到的第二电流值与第二电流值阈值范围进行比较,从而可以判断出空调器室内风机是否异常。这里第二电流阈值范围与第一电流阈值范围可以一致,也可以不一致。例如,设定a≤b≤c≤d,预设的第一电流阈值范围为[a,d],则预设的第二电流阈值范围可以是[a,d]、[a,c]、[a,b]以及[b,c]等。
实际应用中,由于空调器室内风机的电流还与空调器室内风机所处的空气温度有关,不同环境温度下,空调器室内风机在相同档位下的正常电流范围也会不同,在判断第二电流值是否在预设的第二电流阈值范围内之前,可以建立空气温度和第二电流阈值范围的映射关系,并获取当前空气温度,之后将第二电流值与当前空气温度对应的第二电流阈值范围对比,以提高判断精确性。
在另一可选实施例中,可以控制空调器室内风机按照预设的第二检测模式运行,其中,第二检测模式配置成使空调器室内风机在设定的多个档位间切换运行,并获取空调器室内风机在设定的多个档位下的多个运行电流,进而基于多个运行电流获取空调器室内风机在设定的多个档位间切换运行下的电流变化规律,判断电流变化规律是否与预设的电流变化趋势一致,若否,则判断空调器室内风机异常。在本可选实施例中,第二检测模式配置成使空调器室内风机在设定的多个档位间切换运行,并且在自清洁后,可以对空调器室内风机在设定的多个档位间切换时的每个设定档位下的运行电流进行检测,进而可以获得多个档位下的多个运行电流值,根据该多个运行电流值获取空调器室内风机在设定的多个档位间切换运行下的电流变化规律,并将该电流变化规律与预设的电流变化趋势进行比较,以判断空调器室内风机是否异常。基于本可选实施例的方案能够通过空调器室内风机在设定的多个档位间切换运行时的电流变换规律和预设的电流变化趋势的对比来判断空调器室内风机是否异常,提高了判断的精确性,进一步减少了滤网清洗提示误报。
在一实施例中,基于多个运行电流获取空调器室内风机在设定的多个档位间切换运行下的电流变化规律,可以包括:提取多个运行电流的特征信息,并根据提取到的特征信息确定空调器室内风机在设定的多个档位间切换运行下的电流变换规律。特征信息可以包括:电流大小或电流变化特征。这里电流变化特征指在电流动态变化过程中电流的变化关系,例如线性度、变动速度等。
当提取的特征信息为电流时,预设的电流变化趋势可以是电流大小关系,例如从低到高、从高到低、或呈周期性变换。
当提取的特征信息为电流变化特征时,预设的电流变化趋势可以是电流的线性度,也可以是电流的变动速度。
举例说明,在第二检测模式下设定有四个档位:第一档位、第二档位、第三档位和第四档位,每个档位下的风量不同,上述四个档位分别对应微风、低风、中风、高风,设定空调器室内风机在第一档位、第二档位、第三档位和第四档位之间切换运行,对应第一档位、第二档位、第三档位和第四档位的运行电流分别为e,f,g,h。在确定e,f,g,h之间的变化规律时,可以获取e,f,g,h的电流值,然后根据e,f,g,h的电流值大小确定e,f, g,h之间的变化规律,如从低到高,还可以计算e,f,g,h的线性度,进而根据e,f,g,h的线性度确定e,f,g,h之间的变化规律,还可以计算e,f,g,h的变动速度,进而根据变动速度确定e,f,g,h之间的变化规律。确定完各档位下的运行电流的变化规律后,对比预设的电流变化趋势和e,f,g,h之间的变化规律,若该变换规律和预设的电流变化趋势一致,则可以判定空调器正常,此时无需进行滤网清洗提示。但如果e,f,g,h之间的变化规律与预设的电流变化趋势不一致,则判定空调器异常,并控制空调器发出滤网清洗提示信号以提醒用户进行滤网清洗。
为了更好地对比电流变化情况,可以将预设的电流变换趋势绘制成图表一,将多个档位下的多个运行电流绘制成图表二,进而将图表一和图表二进行对比,根据对比结果判断空调器是否异常。当然,也可以将电流变换趋势以及多个档位下的多个运行电流同时绘制在一个图表中,进而在一个图表中对比电流变化情况。
对于步骤S108中提及的控制空调器发出滤网清洗提示信号,本发明提供了多种可选方案。例如,空调器可以包括显示面板,控制空调器发出滤网清洗提示信号可以包括:将滤网清洗提示信号显示在显示面板上。又例如空调器可以包括语音播报装置,控制空调器发出滤网清洗提示信号可以包括:将滤网清洗提示信号发送至语音播报装置,以通过语音播报装置播放滤网清洗提示信号。再例如,空调器可以与移动终端信号连接,控制空调器发出滤网清洗提示信号可以包括:将滤网清洗提示信号发送至与该空调器信号连接的移动终端,以触发移动终端进行滤网清洗提示。
图2是根据本发明另一个实施例的空调器滤网清洗提示方法的示意图。如图2所示,在本实施例中,步骤S108之后,还可以包括步骤S110至步骤S114:
步骤S110,检测滤网安装事件;
步骤S112,在检测到滤网安装事件时,获取空调器室内风机在预设档位下的第三电流值;
步骤S114,判断第三电流值是否在预设的第三电流阈值范围内,若否,则控制空调器发出排查遮挡物提示信号,以提示用户进行遮挡物排查。
基于本实施例提供的方案,能够检测滤网安装事件,并在检测到滤网安装事件时,获取空调器室内风机在预设档位下的第三电流值,进而在第三电 流值不在第三电流阈值范围内时,控制空调器发出排查遮挡物提示信号,以提示用户进行遮挡物排查,从而有效排除了因进风口存在遮挡物导致的空调器室内风机的电流异常引发的滤网清洗提示误报现象,进一步减小了滤网清洗提示误报。
空调器滤网脏堵时,需拆下清洗或更换新滤网,并将清洗后的滤网或新滤网重新安装于空调器室内机上,在这种情形下,为了获知滤网安装事件,空调器进一步可以包括传感器,进而通过传感器来检测滤网安装事件。
图3是根据本发明再一个实施例的空调器滤网清洗提示方法的示意图。如图3所示,在本实施例中,空调器滤网清洗提示方法还可以包括步骤S302和步骤S304:
步骤S302,在空调器安装于使用环境首次上电后,获取空调器室内风机在预设档位下的第四电流值;
步骤S304,判断第四电流值是否在预设的第四电流阈值范围内,若否,则控制空调器发出排查遮挡物提示信号,以提示用户进行遮挡物排查。
使用环境可以是用户的家中或工作环境中,本实施例可以获取空调器安装于使用环境首次上电后在预设档位下的第四电流值,由于此时蒸发器和滤网脏、蒸发器上附着冷凝水的可能性极低,因此,在第四电流值不在预设的第四电流阈值范围内时,可以判定进风口有遮挡物存在,进而控制空调器发出排查遮挡物提示信号,以提示用户进行遮挡物排查。
图4是根据本发明又一个实施例的空调器滤网清洗提示方法的示意图。如图4所示,在本实施例中,空调器滤网清洗提示方法还可以包括步骤S402和步骤S404:
步骤S402,在空调器出厂测试过程中,获取空调器室内风机在预设档位下的第五电流值;
步骤S404,判断第五电流值是否在预设的第五电流阈值范围内,若否,则控制空调器发出蒸发器故障提示信号,以提示用户检修蒸发器。
在本实施例中,由于空调器出厂测试过程中,蒸发器和滤网脏、蒸发器上附着冷凝水的可能性没有,因此,在第五电流值不在预设的第五电流阈值范围内时,则可以判定蒸发器故障,同时控制空调器发出蒸发器故障提示信号,以提示生产测试人员检修蒸发器。例如,在空调器出厂测试过程中,若获取空调器室内风机在预设档位下第五电流值小于第五电流阈值范围的最 小值,则认为蒸发器倒片严重,需重新返修蒸发器。
需要说明的是,本实施例中的第一电流阈值范围、第二电流阈值范围、第三电流阈值范围、第四电流阈值范围以及第五电流阈值范围可以一致,也可以不一致。通过设定多个电电流阈值范围,使得滤网清洗提示更加灵活。
依据本发明另一个方面,在一实施例中,还提供了一种空调器500,图5是根据本发明一个实施例的空调器500的示意框图。如图5所示,本实施例的空调器500可以包括:控制器510,包括存储器511以及处理器512,存储器511内存储有程序,程序被处理器512执行时用于实现根据上述任一实施例的空调器滤网清洗提示方法。
在本发明实施例提供的方案中,通过获取空调器室内风机在预设档位下的第一电流值,并判断第一电流值是否在预设的第一电流阈值范围内,若否,则控制空调器执行自清洁,并在空调器自清洁结束后,通过控制空调器室内风机按照预设的检测模式运行,并获取空调器室内风机在检测模式下的检测电流,然后提取检测电流的特征信息,并根据提取到的特征信息判断空调器室内风机是否异常,并在确定空调器异常时,控制空调器发出滤网清洗提示信号,从而能够提示用户进行滤网清洗。本发明实施例可以实现对运行中空调器室内风机的电流的检测,在检测到预设档位下的第一电流值不在预设的第一电流阈值范围内时,自动控制空调器执行自清洁,使得空调器蒸发器保持干净,同时通过对自清洁后空调器室内风机在检测模式下的检测电流的特征信息的判断,可以对引起滤网清洗提示误报的可能性进行排查,有效排除了因蒸发器脏和/或蒸发器上有冷凝水等原因导致的空调器室内风机的电流异常引发的滤网清洗提示误报现象,有效减少滤网清洗提示误报现象的发生,提高滤网清洗提示的准确性,提升用户的使用体验。
进一步地,本发明实施例的检测模式可以配置成使空调器室内风机在设定的多个档位间切换运行,因而,能够通过空调器室内风机在设定的多个档位间切换运行时的电流变换规律和预设的电流变化趋势的对比来判断空调器室内风机是否异常,提高了判断的精确性,进一步减少了滤网清洗提示误报。
至此,本领域技术人员应认识到,虽然本文已详尽示出和描述了本发明的多个示例性实施例,但是,在不脱离本发明精神和范围的情况下,仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或 修改。因此,本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
