技术领域
本发明涉及空调技术领域,具体而言,涉及一种空调器中四通阀故障的处理方法、处理装置及空调器。
背景技术
现有的冷暖空调器均采用四通阀换向进行模式切换,使用频率比较高,但随着空调器的运行,空调器会产生异物,比如:压缩机缸体磨损颗粒,系统焊渣等,虽然大多数空调器中均设置有过滤网、过滤器等用于隔离异物,但仍有一些异物因产生位置特殊,或直径较小等原因不能够被滤网隔离,因此,该类异物极易进入到四通阀活塞上泄孔内,而造成四通阀发生不换向或不完全换向的故障。同时,四通阀不换向或不完全换向的故障导致空调器不能正常工作时,其维修工作量非常大。
因此,如何设计出一种能够在四通阀出现换向故障时,对四通阀进行自动维修的空调器中四通阀故障的处理方法及处理装置成为目前亟待解决的问题。

在该技术方案中,在对四通阀进行供电预设时间或电磁阀换向预设次数后,空调器还可判断四通阀能否正常换向,从而在四通阀能够正常换向时,即可判断出异物已经被冲除掉了,因而即可结束对该四通阀的故障处理,反之,若四通阀依旧不能够正常换向,则说明异物不能被冲除掉,因此,便可发出语音、声音、光等报警提示,以提示用户对空调器进行手动维修,从而使得该空调器,一方面能够在四通阀出现换向故障时,对四通阀自动进行维修,另一方面,还可在空调器对四通阀进行自动维修失败后及时通知用户,以便用户对其进行手动维修。

在上述技术方案中,优选地,所述判断所述四通阀能否正常换向具体包括:将空调器的工作模式设定为预设工作模式;检测室内换热器的温度和室内环境的温度,和/或检测室内换热器的温度和室外换热器的温度,和/或检测室外换热器的温度和室外环境的温度;通过所述室内换热器的温度和所述室内环境的温度之差,和/或所述室内换热器的温度和所述室外换热器的温度之差,和/或所述室外换热器的温度和所述室外环境的温度之差确定出所述空调器的实际运行模式;判断所述空调器的实际运行模式与所述预设工作模式是否匹配,若所述空调器的实际运行模式与所述预设工作模式匹配,则判定所述四通阀能够正常换向,若所述空调器的实际运行模式与所述预设工作模式不匹配,则判定四通阀不能正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行 模式的具体过程为:判断所述室内换热器的温度是否大于等于所述室内环境的温度与第一预设温度值之和,若所述室内换热器的温度大于等于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式匹配;其中,所述第一预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室内环境的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器相当于一个蒸发器,其内的冷媒在蒸发吸热后产生冷量,而其产生的冷量只能够通过热传递而传递到室内,因此,室内的冷量来源于室内换热器,而根据能量的传递定律可知,室内换热器的温度必然要低于室内环境温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室内环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室内换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第一预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在设定的工作模式为制冷或抽湿模式的前提下判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的高于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室 内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式的具体过程为:判断所述室内换热器的温度是否小于等于所述室内环境的温度与第二预设温度值之和,若所述室内换热器的温度小于等于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温度大于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第二预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室内环境的热量来源于室内换热器,因此,室内换热器的温度必然要高于室内环境的温度,因此,在预设工作模式为制热模式时,若室内换热器的温度还低于等于室内环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制热时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第二预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制热模式下,在判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的低于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的具体过程为:判断所述室内换热器的温度是否大于等于所述室外换热器的温度,若所述室内换热器的温度大于等于所述室外换热器的温度,则判定所述空调器的实际运行模式不为制冷或抽湿模式,即所述空调器的实际运行模 式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室外换热器的温度,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室外换热器的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器为蒸发器,室外换热器为冷凝器,从而通过冷媒在室内换热器中的不断蒸发吸热及在室外换热器中的不断冷凝散热而将室内的热量不断地散出到室外,进而达到制冷或抽湿的目的。因此根据能量的传递定律可知,在空调器制冷或抽湿时,室内换热器的温度必然要低于室外换热器的温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀依旧不能够正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的具体过程为:判断所述室内换热器的温度是否小于等于所述室外换热器的温度,若所述室内换热器的温度小于等于所述室外换热器的温度,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温度大于所述室外换热器的温度,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式为制热模式时,室外换热器中的冷媒蒸发吸热后将热量源源不断地输送到室内换热器中,进而通过热传递散将热量散发到室内,因此,室内换热器的温度必然要高于室外换热器的温度,因此,在设定的工作模式为制热模式时,若室内换热器的温度还低于等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制热模式,从而可知四通阀依旧不能够正常换向,反之,在室内换热器的温度高于室外换热器的温度时,则可说明四通阀已经能够正常换向,因此即可结束对四通阀的维修。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时, 通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室外换热器的温度是否大于等于所述室外环境的温度与第三预设温度值之和,若所述室外换热器的温度大于等于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温度小于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第三预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室外换热器的温度和室外环境的温度进行四通阀的故障判断过程也不一样,具体地,在空调器进行制冷或抽湿时,室外换热器相当于一个冷凝器,其通过冷媒的冷凝散热将室内的热量散发到室外环境中,因此,只有室外换热器的温度低于室外环境的温度时,空调器才能够实现制冷或抽湿,即空调器制冷或抽湿时,室外换热器的温度必然要低于室外环境温度,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度还高于或等于室外环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室外换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第三预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制冷或抽湿模式下,对四通阀能否正常换向的判断过程中,只有在室外换热器的温度比室外环境温度的高1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室 外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式具体为:判断所述室外换热器的温度是否小于等于所述室外环境的温度与第四预设温度值之和,若所述室外换热器的温度小于等于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温度大于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第四预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室外换热器通过冷媒的蒸发吸热不断地将热量输送到室内,即室外换热器源源不断地从室外环境中吸取热量,从而使得室外换热器的高于室外环境的温度,因此,在用户设定的工作模式为制热模式时,若室外换热器的温度还低于等于室外环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制热时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案提供的四通阀故障的处理方法也适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第四预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采用检测时,一般存在着1℃的正负偏差,因此,在制热模式下,对四通阀能否正常换向的判断过程中,只有在室外换热器的温度比室外环境温度的低1℃及更多时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
本发明第二方面的实施例提供了一种空调器中四通阀故障的处理装置,包括:采集单元,用于采集四通阀换向状态信号;处理单元,在采集到的所述四通阀换向状态信号为异常信号时,向所述四通阀发送换向控制信号,使所述四 通阀进行换向。
根据本发明第二方面的实施例提供的空调器中四通阀故障的处理装置,可通过采集四通阀的换向状态信号,并在采集到异常的换向状态信号后向四通阀发送换向控制信号,以使四通阀进行换向,进而便可通过四通阀滑块的换向而将四通阀活塞上泄孔内的异物给冲除掉,进而使得四通阀能够正常换向。该技术方案,通过对四通阀的换向状态信号进行采集,进而可在四通阀出现换向异常时,及时对四通阀进行自动维修。
其中,具体地,该空调器中四通阀故障的处理装置可与空调器中四通阀故障的检测装置相结合使用,从而可利用四通阀故障的检测装置对四通阀的是否出现换向故障进行检测,并在四通阀出现换向故障时发出异常的换向状态信号,从而该空调器中四通阀故障的处理装置便可根据采集到的异常的换向状态信号对四通阀进行及时维修。
在上述技术方案中,优选地,所述处理单元具体用于:在预设时间内以预设频率向所述四通阀间歇性地发送供电信号,使所述四通阀进行多次换向;或向所述四通阀间歇性地发送供电信号,使所述四通阀换向预设次数。
在该技术方案中,可通过向四通阀发送间隙性的供电信号,而使四通阀进行多次换向,具体地,一方面,可通过对发送的电信号的总时间和单位时间内电信号的频率进行控制,而对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于预设时间与预设频率之积。另一方面,也可不管发送的电信号的总时间和单位时间内电信号的频率而直接通过设置发送的电信号的次数来对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于电信号的发送次数。
在上述技术方案中,优选地,所述处理单元还用于:在所述向所述四通阀发送换向控制信号,使所述四通阀进行换向之后,判断所述四通阀是否能正常换向,若所述四通阀不能正常换向,则进行报警提示。具体地,可在向所述四通阀间歇性地发送供电信号所述预设时间或所述四通阀换向预设次数后,判断所述四通阀是否能正常换向,若所述四通阀不能正常换向,则进行报警提示。
在该技术方案中,在对四通阀进行供电预设时间或电磁阀换向预设次数后,空调器还可判断四通阀能否正常换向,从而在四通阀能够正常换向时,即可判断出异物已经被冲除掉了,因而即可结束对该四通阀的故障处理,反之, 若四通阀依旧不能够正常换向,则说明异物不能被冲除掉,因此,便可发出语音、声音、光等报警提示,以提示用户对空调器进行手动维修,从而使得该空调器,一方面能够在四通阀出现换向故障时,对四通阀自动进行维修,另一方面,还可在空调器对四通阀进行自动维修失败后及时通知用户,以便用户对其进行手动维修。
在上述技术方案中,优选地,所述处理单元还用于:在所述向所述四通阀发送换向控制信号,使所述四通阀进行换向之前,判断压缩机是否处于运行状态,若所述压缩机处于运行状态,则关闭所述压缩机。
在该技术方案中,在对四通阀进行多次供电、断电之前,还可检测压缩机是否处于运行状态,从而在预缩机运转时,则可直接关掉压缩机,从而可减轻四通阀换向时四通阀的滑块两端的阻力。当然,在实际过程中,若不考虑四通阀换向时滑块的阻力,也可不关闭压缩机而直接对四通阀进行多次供电、断电控制。
在上述技术方案中,优选地,所述处理单元具体包括:设定单元,将所述空调器的工作模式设定为预设工作模式;检测单元,用于检测室内换热器的温度和室内环境的温度,和/或用于检测室内换热器的温度和室外换热器的温度,和/或用于检测室外换热器的温度和室外环境的温度;确定单元,用于根据所述室内换热器的温度和所述室内环境的温度之差,和/或所述室内换热器的温度和所述室外换热器的温度之差,和/或所述室外换热器的温度和所述室外环境的温度之差确定出所述空调器的实际运行模式;判断单元,判断所述空调器的实际运行模式与所述预设工作模式是否匹配,并在所述空调器的实际运行模式与所述预设工作模式匹配时,判定所述四通阀能够正常换向,及在所述空调器的实际运行模式与所述预设工作模式不匹配时,判定所述四通阀不能正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否大于等于所述室内环境的温度与第一预设温度值之和,若所述室内换热器的温度大于等于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式不是制 冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式匹配;其中,所述第一预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室内环境的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器相当于一个蒸发器,其内的冷媒在蒸发吸热后产生冷量,而其产生的冷量只能够通过热传递而传递到室内,因此,室内的冷量来源于室内换热器,而根据能量的传递定律可知,室内换热器的温度必然要低于室内环境温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室内环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室内换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第一预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在设定的工作模式为制冷或抽湿模式的前提下判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的高于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。

在该技术方案中,当预设工作模式为制热模式时,室外换热器中的冷媒蒸发吸热后将热量源源不断地输送到室内换热器中,进而通过热传递散将热量散发到室内,因此,室内换热器的温度必然要高于室外换热器的温度,因此,在设定的工作模式为制热模式时,若室内换热器的温度还低于等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制热模式,从而可知四通阀依旧不能够正常换向,反之,在室内换热器的温度高于室外换热器的温度时,则可说明四通阀已经能够正常换向,因此即可结束对四通阀的维修。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室外换热器的温度是否大于等于所述室外环境的温度与第三预设温度值之和,若所述室外换热器的温度大于等于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式不是制 冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温度小于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第三预设温度值大于等于检测所述室外换热器的温度时的检测误差值。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点,下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明,但是,本发明还可以采用其他不同于在此描述的其他方式来实施,因此,本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1描述根据本发明一些实施例的空调器中四通阀故障的处理方法。
如图1所示,本发明第一方面的实施例提供了一种空调器中四通阀故障的处理方法,包括:步骤102,采集四通阀换向状态信号;步骤104,在采集到的所述四通阀换向状态信号为异常信号时,向所述四通阀发送换向控制信号,使所述四通阀进行换向。
本发明第一方面的实施例提供的空调器中四通阀故障的处理方法,可通过采集四通阀的换向状态信号,并在采集到异常的换向状态信号后向四通阀发送换向控制信号,以使四通阀进行换向,进而便可通过四通阀滑块的换向而将四通阀活塞上泄孔内的异物给冲除掉,进而使得四通阀能够正常换向。该技术方案,通过对四通阀的换向状态信号进行采集,进而可在四通阀出现换向异常时,及时对四通阀进行自动维修。
其中,具体地,该空调器中四通阀故障的处理方法可与空调器中四通阀故障的检测方法相结合使用,从而可利用四通阀故障的检测方法对四通阀的是否出现换向故障进行检测,并在四通阀出现换向故障时发出异常的换向状态信号,从而该空调器中四通阀故障的处理方法便可根据采集到的异常的换向状态信号对四通阀进行及时维修。
在上述技术方案中,优选地,所述向所述四通阀发送换向控制信号,使所述四通阀进行换向具体为:在预设时间内以预设频率向所述四通阀间歇性地发送供电信号,使所述四通阀进行多次换向;或向所述四通阀间歇性地发送供电信号,使所述四通阀换向预设次数。
在该技术方案中,可通过向四通阀发送间隙性的供电信号,而使四通阀进行多次换向,具体地,一方面,可通过对发送的电信号的总时间和单位时间内电信号的频率进行控制,而对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于预设时间与预设频率之积。另一方面,也可不管发送的电信号的总时间和单位时间内电信号的频率而直接通过设置发送的电信号的次数来对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于电信号的发送次数。
在另一个实施例提供的空调器中四通阀故障的处理方法中,如图2所示,包括:步骤202,采集四通阀换向状态信号;步骤204,在采集到的所述四通阀换向状态信号为异常信号时,判断压缩机是否处于运行状态,若所述压缩机处于运行状态,则关闭所述压缩机;步骤206,在预设时间内以预设频率向所述四通阀间歇性地发送供电信号,使所述四通阀进行多次换向;或向所述四通阀间歇性地发送供电信号,使所述四通阀换向预设次数;步骤208,在向所述四通阀间歇性地发送供电信号所述预设时间或所述四通阀换向预设次数后,判断所述四通阀是否能正常换向,若所述四通阀不能正常换向,则进行报警提示。
在步骤204中,在对四通阀发送换向控制信号之前,还可检测压缩机是否处于运行状态,从而在压缩机运转时,则可直接关掉压缩机,从而可减轻四通阀换向时四通阀的滑块两端的阻力。当然,在实际过程中,若不考虑四通阀换向时滑块的阻力,也可不关闭压缩机而直接向四通阀发送换向控制信号,即直接对四通阀进行多次供电、断电控制。
在步骤208中,在对四通阀进行供电预设时间或电磁阀换向预设次数后,空调器还可判断四通阀能否正常换向,从而在四通阀能够正常换向时,即可判断出异物已经被冲除掉了,因而即可结束对该四通阀的故障处理,反之,若四通阀依旧不能够正常换向,则说明异物不能被冲除掉,因此,便可发出语音、声音、光等报警提示,以提示用户对空调器进行手动维修,从而使得该空调器,一方面能够在四通阀出现换向故障时,对四通阀自动进行维修,另一方面,还可在空调器对四通阀进行自动维修失败后及时通知用户,以便用户对其进行手动维修。
在上述技术方案中,优选地,所述判断所述四通阀能否正常换向具体包括:将空调器的工作模式设定为预设工作模式;检测室内换热器的温度和室内环境的温度,和/或检测室内换热器的温度和室外换热器的温度,和/或检测室外换热器的温度和室外环境的温度;通过所述室内换热器的温度和所述室内环境的温度之差,和/或所述室内换热器的温度和所述室外换热器的温度之差,和/或所述室外换热器的温度和所述室外环境的温度之差确定出所述空调器的实际运行模式;判断所述空调器的实际运行模式与所述预设工作模式是否匹配,若所述空调器的实际运行模式与所述预设工作模式匹配,则判定所述四通阀能够正常换向,若所述空调器的实际运行模式与所述预设工作模式不匹配,则判定四通阀不能正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否大于等于所述室内环境的温度与第一预设温度值之和,若所述室内换热器的温度大于等于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反 之,若所述室内换热器的温度小于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式匹配;其中,所述第一预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室内环境的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器相当于一个蒸发器,其内的冷媒在蒸发吸热后产生冷量,而其产生的冷量只能够通过热传递而传递到室内,因此,室内的冷量来源于室内换热器,而根据能量的传递定律可知,室内换热器的温度必然要低于室内环境温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室内环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室内换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第一预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在设定的模式为制冷或抽湿时,在判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的高于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式具体为:判断所述室内换热器的温度是否小于等于所述室内环境的温度与第二预设温度值之和,若所述室内换热器的温度小于等于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温 度大于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第二预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室内环境的热量来源于室内换热器,因此,室内换热器的温度必然要高于室内环境的温度,因此,在预设工作模式为制热模式时,若室内换热器的温度还低于等于室内环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制热时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第二预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制热模式下,在判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的低于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否大于等于所述室外换热器的温度,若所述室内换热器的温度大于等于所述室外换热器的温度,则判定所述空调器的实际运行模式不为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室外换热器的温度,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室外换热器的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器 进行制冷或抽湿时,室内换热器为蒸发器,室外换热器为冷凝器,从而通过冷媒在室内换热器中的不断蒸发吸热及在室外换热器中的不断冷凝散热而将室内的热量不断地散出到室外,进而达到制冷或抽湿的目的。因此根据能量的传递定律可知,在空调器制冷或抽湿时,室内换热器的温度必然要低于室外换热器的温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀依旧不能够正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否小于等于所述室外换热器的温度,若所述室内换热器的温度小于等于所述室外换热器的温度,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温度大于所述室外换热器的温度,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式为制热模式时,室外换热器中的冷媒蒸发吸热后将热量源源不断地输送到室内换热器中,进而通过热传递散将热量散发到室内,因此,室内换热器的温度必然要高于室外换热器的温度,因此,在设定的工作模式为制热模式时,若室内换热器的温度还低于等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制热模式,从而可知四通阀依旧不能够正常换向,反之,在室内换热器的温度高于室外换热器的温度时,则可说明四通阀已经能够正常换向,因此即可结束对四通阀的维修。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室外换热器的温度是否大于等于所述室外环境的温度与第三预设温度值之和,若所述室外换热器的温度大于等于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若 所述室外换热器的温度小于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第三预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室外换热器的温度和室外环境的温度进行四通阀的故障判断过程也不一样,具体地,在空调器进行制冷或抽湿时,室外换热器相当于一个冷凝器,其通过冷媒的冷凝散热将室内的热量散发到室外环境中,因此,只有室外换热器的温度低于室外环境的温度时,空调器才能够实现制冷或抽湿,即空调器制冷或抽湿时,室外换热器的温度必然要低于室外环境温度,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度还高于或等于室外环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室外换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第三预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制冷或抽湿模式下,对四通阀能否正常换向的判断过程中,只有在室外换热器的温度比室外环境温度的高1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式具体为:判断所述室外换热器的温度是否小于等于所述室外环境的温度与第四预设温度值之和,若所述室外换热器的温度小于等于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温 度大于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第四预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室外换热器通过冷媒的蒸发吸热不断地将热量输送到室内,即室外换热器源源不断地从室外环境中吸取热量,从而使得室外换热器的高于室外环境的温度,因此,在用户设定的工作模式为制热模式时,若室外换热器的温度还低于等于室外环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制热时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案提供的四通阀故障的处理方法也适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第四预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采用检测时,一般存在着1℃的正负偏差,因此,在制热模式下,对四通阀的能否正常换向的判断的过程中,只有在室外换热器的温度比室外环境温度的低1℃及更多时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
图3a示出了根据本发明的一个实施例的空调器中四通阀故障的处理装置300的结构示意框图。
本发明第二方面的实施例提供了一种空调器中四通阀故障的处理装置300,如图3a所示,包括:采集单元310,用于采集四通阀换向状态信号;处理单元320,在采集到的所述四通阀换向状态信号为异常信号时,向所述四通阀发送换向控制信号,使所述四通阀进行换向。
根据本发明第二方面的实施例提供的空调器中四通阀故障的处理装置300,可通过采集四通阀的换向状态信号,并在采集到异常的换向状态信号后 向四通阀发送换向控制信号,以使四通阀进行换向,进而便可通过四通阀滑块的换向而将四通阀活塞上泄孔内的异物给冲除掉,进而使得四通阀能够正常换向。该技术方案,通过对四通阀的换向状态信号进行采集,进而可在四通阀出现换向异常时,及时对四通阀进行自动维修。
其中,具体地,该空调器中四通阀故障的处理装置300可与空调器中四通阀故障的检测装置相结合使用,从而可利用四通阀故障的检测装置对四通阀的是否出现换向故障进行检测,并在四通阀出现换向故障时发出异常的换向状态信号,从而该空调器中四通阀故障的处理装置便可根据采集到的异常的换向状态信号对四通阀进行及时维修。
在上述技术方案中,优选地,所述处理单元320具体用于:在预设时间内以预设频率向所述四通阀间歇性地发送供电信号,使所述四通阀进行换向;或向所述四通阀间歇性地发送供电信号,使所述四通阀换向预设次数。
在该技术方案中,可通过向四通阀发送间隙性的供电信号,而使四通阀进行多次换向,具体地,一方面,可通过对发送的电信号的总时间和单位时间内电信号的频率进行控制,而对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于预设时间与预设频率之积。另一方面,也可不管发送的电信号的总时间和单位时间内电信号的频率而直接通过设置发送的电信号的次数来对电磁阀的换向次数进行控制,此时,电磁阀的换向次数等于电信号的发送次数。
在上述技术方案中,优选地,所述处理单元320还用于:在所述向所述四通阀发送换向控制信号,使所述四通阀进行换向之后,判断所述四通阀是否能正常换向,若所述四通阀不能正常换向,则进行报警提示。具体地,可在向所述四通阀间歇性地发送供电信号所述预设时间或所述四通阀换向预设次数后,判断所述四通阀是否能正常换向,若所述四通阀不能正常换向,则进行报警提示。
在该技术方案中,在对四通阀进行供电预设时间或电磁阀换向预设次数后,空调器还可判断四通阀能否正常换向,从而在四通阀能够正常换向时,即可判断出异物已经被冲除掉了,因而即可结束对该四通阀的故障处理,反之,若四通阀依旧不能够正常换向,则说明异物不能被冲除掉,因此,便可发出语音、声音、光等报警提示,以提示用户对空调器进行手动维修,从而使得该空 调器,一方面能够在四通阀出现换向故障时,对四通阀自动进行维修,另一方面,还可在空调器对四通阀进行自动维修失败后及时通知用户,以便用户对其进行手动维修。
在上述技术方案中,优选地,所述处理单元320还用于:在所述向所述四通阀发送换向控制信号,使所述四通阀进行换向之前,判断压缩机是否处于运行状态,若所述压缩机处于运行状态,则关闭所述压缩机。
在该技术方案中,在对四通阀进行多次供电、断电之前,还可检测压缩机是否处于运行状态,从而在预缩机运转时,则可直接关掉压缩机,从而可减轻四通阀换向时四通阀的滑块两端的阻力。当然,在实际过程中,若不考虑四通阀换向时滑块的阻力,也可不关闭压缩机而直接对四通阀进行多次供电、断电控制。
在上述技术方案中,优选地,如图3b所示,所述处理单元320具体包括:设定单元322,将所述空调器的工作模式设定为预设工作模式;检测单元324,用于检测室内换热器的温度和室内环境的温度,和/或用于检测室内换热器的温度和室外换热器的温度,和/或用于检测室外换热器的温度和室外环境的温度;确定单元326,用于根据所述室内换热器的温度和所述室内环境的温度之差,和/或所述室内换热器的温度和所述室外换热器的温度之差,和/或所述室外换热器的温度和所述室外环境的温度之差确定出所述空调器的实际运行模式;判断单元328,判断所述空调器的实际运行模式与所述预设工作模式是否匹配,并在所述空调器的实际运行模式与所述预设工作模式匹配时,判定所述四通阀能够正常换向,及在所述空调器的实际运行模式与所述预设工作模式不匹配时,判定所述四通阀不能正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否大于等于所述室内环境的温度与第一预设温度值之和,若所述室内换热器的温度大于等于所述室内环境的温度与所述第一预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室内环境的温度与所述第一预设温度值 之和,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式匹配;其中,所述第一预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室内环境的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器相当于一个蒸发器,其内的冷媒在蒸发吸热后产生冷量,而其产生的冷量只能够通过热传递而传递到室内,因此,室内的冷量来源于室内换热器,而根据能量的传递定律可知,室内换热器的温度必然要低于室内环境温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室内环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室内换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第一预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在设定的模式为制冷或抽湿时,在判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的高于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室内换热器的温度和室内环境的温度之差确定出所述空调器的实际运行模式具体为:判断所述室内换热器的温度是否小于等于所述室内环境的温度与第二预设温度值之和,若所述室内换热器的温度小于等于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温度大于所述室内环境的温度与所述第二预设温度值之和,则判定所述空调器的 实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第二预设温度值大于等于检测所述室内换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室内环境的热量来源于室内换热器,因此,室内换热器的温度必然要高于室内环境的温度,因此,在预设工作模式为制热模式时,若室内换热器的温度还低于等于室内环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室内换热器的温度时的检测误差,因此,在预设工作模式为制热时,若室内换热器的温度越高于或越低于室内环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第二预设温度值大于等于1℃。
具体地,在现有的空调器中,对室内换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制热模式下,在判断四通阀能否正常换向时,只有在室内换热器的温度比室内环境温度的低于1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否大于等于所述室外换热器的温度,若所述室内换热器的温度大于等于所述室外换热器的温度,则判定所述空调器的实际运行模式不为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,反之,若所述室内换热器的温度小于所述室外换热器的温度,则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式不同时,在利用室内换热器的温度和室外换热器的温度判断四通阀能否正常换向的过程也不一样,具体地,在空调器进行制冷或抽湿时,室内换热器为蒸发器,室外换热器为冷凝器,从而通过冷 媒在室内换热器中的不断蒸发吸热及在室外换热器中的不断冷凝散热而将室内的热量不断地散出到室外,进而达到制冷或抽湿的目的。因此根据能量的传递定律可知,在空调器制冷或抽湿时,室内换热器的温度必然要低于室外换热器的温度,因此,在预设工作模式为制冷或抽湿模式时,若室内换热器的温度还高于或等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀依旧不能够正常换向。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室内换热器的温度和室外换热器的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室内换热器的温度是否小于等于所述室外换热器的温度,若所述室内换热器的温度小于等于所述室外换热器的温度,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室内换热器的温度大于所述室外换热器的温度,则判定所述空调器的实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配。
在该技术方案中,当预设工作模式为制热模式时,室外换热器中的冷媒蒸发吸热后将热量源源不断地输送到室内换热器中,进而通过热传递散将热量散发到室内,因此,室内换热器的温度必然要高于室外换热器的温度,因此,在设定的工作模式为制热模式时,若室内换热器的温度还低于等于室外换热器的温度,则必然可知,空调器的实际运行模式不是制热模式,从而可知四通阀依旧不能够正常换向,反之,在室内换热器的温度高于室外换热器的温度时,则可说明四通阀已经能够正常换向,因此即可结束对四通阀的维修。
在上述技术方案中,具体地,在所述预设工作模式为制冷或抽湿模式时,通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式的过程具体为:判断所述室外换热器的温度是否大于等于所述室外环境的温度与第三预设温度值之和,若所述室外换热器的温度大于等于所述室外环境的温度与所述第三预设温度值之和,则判定所述空调器的实际运行模式不是制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温度小于所述室外环境的温度与所述第三预设温度值之和, 则判定所述空调器的实际运行模式为制冷或抽湿模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第三预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式不同时,在利用室外换热器的温度和室外环境的温度进行四通阀的故障判断过程也不一样,具体地,在空调器进行制冷或抽湿时,室外换热器相当于一个冷凝器,其通过冷媒的冷凝散热将室内的热量散发到室外环境中,因此,只有室外换热器的温度低于室外环境的温度时,空调器才能够实现制冷或抽湿,即空调器制冷或抽湿时,室外换热器的温度必然要低于室外环境温度,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度还高于或等于室外环境温度,则必然可知,空调器的实际运行模式不是制冷或抽湿模式,即四通阀未正常换向或未完全换向,进而即可判定出四通阀并不能够正常换向,但考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制冷或抽湿时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能正常换向,因此,该技术方案适当地考虑了检测室外换热器的温度时的检测误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第三预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采样检测时,一般存在着1℃的正负偏差,因此,在制冷或抽湿模式下,对四通阀能否正常换向的判断过程中,只有在室外换热器的温度比室外环境温度的高1℃及以上时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
在上述技术方案中,具体地,在所述预设工作模式为制热模式时,通过室外换热器的温度和室外环境的温度之差确定出所述空调器的实际运行模式具体为:判断所述室外换热器的温度是否小于等于所述室外环境的温度与第四预设温度值之和,若所述室外换热器的温度小于等于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的实际运行模式为非制热模式,即所述空调器的实际运行模式与所述预设工作模式不匹配,若所述室外换热器的温度大于所述室外环境的温度与所述第四预设温度值之和,则判定所述空调器的 实际运行模式为制热模式,即所述空调器的实际运行模式与所述预设工作模式相匹配;其中,所述第四预设温度值大于等于检测所述室外换热器的温度时的检测误差值。
在该技术方案中,当预设工作模式为制热模式时,室外换热器通过冷媒的蒸发吸热不断地将热量输送到室内,即室外换热器源源不断地从室外环境中吸取热量,从而使得室外换热器的高于室外环境的温度,因此,在用户设定的工作模式为制热模式时,若室外换热器的温度还低于等于室外环境温度,则必然可知,空调器的实际运行模式不是制热模式,从而即可判定出四通阀未换向或未完全换向,即四通阀依旧不能够正常换向,但同样考虑到检测室外换热器的温度时的检测误差,因此,在用户设定的工作模式为制热时,若室外换热器的温度越高于或越低于室外环境温度,其并不一定能够说明四通阀不能够正常换向,因此,该技术方案提供的四通阀故障的处理方法也适当地考虑了温度检测的误差,从而可防止因为温度检测误差的原因而错误地判断出四通阀依旧不能正常换向的情况发生。
在上述技术方案中,优选地,所述第四预设温度值大于等于1℃。
具体地,在现有的空调器中,对室外换热器进行温度采用检测时,一般存在着1℃的正负偏差,因此,在制热模式下,对四通阀的能否正常换向的判断过程中,只有在室外换热器的温度比室外环境温度的低1℃及更多时才能说明四通阀依旧不能正常换向,从而可避免在四通阀能够正常换向时,而错误地认为四通阀依旧不能够正常换向的情况发生。
如图4所示,本发明第三方面的实施例提供了一种空调器400,包括第二方面任一项实施例所述的空调器中四通阀故障的处理装置300。
本发明第三方面的实施例提供的空调器400,包括第二方面任一项实施例所述的空调器中四通阀故障的处理装置300,因此,具有第二方面任一项实施例所述的空调器中四通阀故障的处理装置的有益效果,在此不再赘述。
下面结合图5描述根据本发明的另一个实施例的所述空调器中四通阀故障的处理方法,具体包括以下步骤:步骤501,采集四通阀换向状态信号;步骤502,在采集到的所述四通阀换向状态信号为异常信号时,判断压缩机是否处于运行状态,若所述压缩机处于运行状态,则关闭所述压缩机;步骤503, 在预设时间内以预设频率向所述四通阀间歇性地发送供电信号,使所述四通阀进行多次换向;或在采集到的所述四通阀换向状态信号为异常信号时,向所述四通阀间歇性地发送供电信号,使所述四通阀换向预设次数;步骤504,在向所述四通阀间歇性地发送供电信号所述预设时间或所述四通阀换向预设次数后,将空调器的工作模式设定为预设工作模式;步骤505,检测室内换热器的温度和室内环境的温度,若预设工作模式为制热或抽湿模式,则转步骤506,若所述预设工作模式为制热模式,则转步骤507;步骤506,判断室内换热器的温度T2是否大于等于室内环境的温度T1与第一预设温度值a℃之和,若T2≥T1+a℃,则转步骤508,若T2<T1+a℃,则转步骤509;步骤507,判断室内换热器的温度T2是否小于等于室内环境的温度T1与第二预设温度值b℃之和,若T2≤T1+b℃,则转步骤508,若T2>T1+b℃,则转步骤509;步骤508,进行报警提示;步骤509,判定四通阀能够正常换向。
在步骤506和步骤507中,具体地,比如,第一预设温度值a和第二预设温度值b可选取1℃,则当预设工作模式为制热模式时,若检测出室内环境温度T1为15℃,室内换热器的温度T2为15.5℃,即T2<T1+1℃,则认为四通阀依旧不能够正常换向(此时,0.5摄氏度的温差有可能为系统采样偏差,因此,虽然室内换热器的温度T2大于室内环境温度T1,但依旧判定四通阀不能够正常换向,因为,若四通阀能够正常换向的话,室内换热器的温度应该会远远大于室内环境温度),从而即可说明,经过多次供电、断电后而使四通阀换向多次后,依旧不能够解决四通阀的换向故障,此时,则可直接进行报警提示,以便及时通知用户对四通阀进行手动维修。同理,当预设工作模式为制热模式时,若检测出室内环境温度T1为15℃,室内换热器的温度T2为20℃,即T2>T1+1℃,则认为四通阀能够正常换向,从而即可结束对四通阀的故障过程。
