图1是根据本发明一个实施例的冰箱的示意性结构框图，参见图1所示，本发明的冰箱100包括给间室提供冷量的压缩机140、循环风道、位于循环风道内的蒸发器和风机110，用于启闭连通间室和循环风道的多个出风口的风门150，给风机110进行化霜的加热装置130、报警设备120。控制设备200与其他电气元件通讯连接，控制设备200包括可包括存储器220和处理器210，存储器内220存储有计算机程序221，计算机程序221被处理器210执行时用于实现以下任一实施例中的冰箱的控制方法。
其中，加热装置130可包括位于蒸发器下方的加热丝或加热管等。
其中，风机110包括PWM输入端，用于控制所述风机110的输入占空比，实现风机110转速控制；同时，所述风机110还包括反馈输出端，向所述主控单元提供风机110实际转速。
其中，控制设备200可以与冰箱100数据相连，其可以布置在服务器、云端等网络侧设备处；控制设备200也可以为集控设备，布置在冰箱100所在的环境或周围环境中。控制设备200与冰箱100的数据连接方式包括但不限于无线传输、红外传输、超声传输等；另外，控制设备200还可以作为冰箱100的一部分，设置在冰箱100的内部。
图2是根据本发明一个实施例的冰箱的控制方法的流程示意图。参见图2所示，本发明由上述任一实施例的控制设备200执行的冰箱的控制方法可以至少包括如下步骤S202-S206。
步骤S202：获取冰箱100的风机110的运行状态，根据运行状态识别风机110是否处于故障状态；
步骤S204：若是，确定风机110的故障类型，获取冰箱100内预先配置的与故障类型对应的故障消除策略；
步骤S206：控制冰箱100按照相应的故障消除策略运行。
其中，上述判断风机是否处于故障状态包括但不限于通过以下方式：通过PWM控制输入端输入既定功率P0，风机反馈的实际转速n与既定功率P0下的风机既定转速N存在一定的转速差值或风机110未反馈信号，则确定风机110处于故障状态。
本发明实施例中，获取冰箱100的风机110的运行状态并根据运行状态 识别到风机110处于故障状态后，则确定风机110的故障类型，获取冰箱100内预先配置的与故障类型对应的故障消除策略，控制冰箱100按照相应的故障消除策略运行，从而可使风机110尽快达到正常状态，避免影响冰箱100的制冷效果。
其中，上述确定风机110的故障类型包括但不限于通过以下方式：通过PWM控制输入端输入既定功率P0后，若风机110反馈的实际转速n与既定功率P0下的风机110既定转速N存在一定的转速差值，则可确定风机110的故障类型是结霜故障；若风机110未反馈信号，则可确定风机110的故障类型是断电故障。
进一步地，上文步骤S204提到的获取冰箱100内预先配置的与故障类型对应的故障消除策略，可以包括：若故障类型为断电停机，则获取故障报警策略；若故障类型为冻死停机，则获取故障化霜策略。
接下来，控制冰箱100按照故障报警策略运行，可以包括：控制冰箱100发出报警信号；且检测冰箱100的间室的温度超过第一设定温度，控制冰箱100的压缩机140和风门150开启直至间室的温度低于第二设定温度，控制压缩机140和风门150关闭。
其中，可选通过冰箱100上设置的报警设备120发出报警信号以提醒用户冰箱100的风机110出现断电故障以尽快对其维修。检测冰箱100的间室的温度超过第一设定温度，控制冰箱100的压缩机140和风门150开启直至间室的温度低于第二设定温度，控制压缩机140和风门150关闭，通过自然对流维持冰箱100间室温度从而可避免风机出现断电故障后冰箱100间室温度波动大，影响冰箱100制冷效果。
另外，控制冰箱100按照故障化霜策略运行，可以包括：控制冰箱100的压缩机140关闭、加热装置130开启，直至冰箱100的化霜传感器检测到的温度达到第三设定温度，关闭加热装置130。
其中，在确定风机110出现结霜故障后，控制冰箱100及时按照故障化霜策略运行，以免影响制冷效果，在化霜传感器检测到的温度达到第三设定温度后，关闭加热装置130，从而可避免造成间室温度过高。
进一步地，在本发明一个实施例中，上述关闭加热装置130后，该方法还可以包括：判断风机110是否处于故障状态；若风机110处于故障状态，则控制冰箱100继续按照故障化霜策略运行直至冰箱100按照故障化霜策略 运行的时长达到第一设定时长；或在风机110处于正常状态时，控制冰箱100退出故障化霜策略；若风机110处于正常状态，则控制冰箱100按照普通化霜策略运行。其中，普通化霜策略即冰箱100运行预设时长后，控制压缩机140、风机110关闭、加热装置130开启，直至化霜传感器检测到温度达到预设温度时，控制加热装置130关闭，压缩机140、风机110开启。
其中，在判断风机110处于故障状态的情况下，则控制冰箱100继续按照故障化霜策略运行后直至冰箱100按照故障化霜策略运行的时长达到第一设定时长控制冰箱100退出故障化霜策略，从而可防止冰箱100运行化霜策略时间过长而导致冰箱100间室温度过高。
在本发明一个实施例中，上述控制冰箱100继续按照故障化霜策略运行，可包括：化霜传感器检测到温度达到第四设定温度，控制加热装置130开启；化霜传感器检测到温度达到第三设定温度，控制加热装置130关闭；并在每次控制加热装置130关闭时判断风机110是否处于故障状态和/或冰箱100按照故障化霜策略运行的时长是否达到第一设定时长，第四设定温度小于第三设定温度。
其中，第四设定温度可选为18-22度，优选为20度，第三设定温度可选为8-12度，优选为10度，第三设定温度和第四设定温度可根据实际情况设定，本发明不做过多限定。
其中，化霜传感器检测到温度达到第四设定温度，控制加热装置130开启；化霜传感器检测到温度达到第三设定温度，控制加热装置130关闭。循环上述步骤可避免冰箱100间室温度过高。
在本发明一个实施例中，为了进一步避免冰箱100间室温度过高，每次判断风机110处于故障状态和冰箱100按照所述故障化霜策略运行的时长小于第一设定时长时控制压缩机140开启；化霜传感器检测到温度达到第四设定温度，控制压缩机140关闭。
另外，在本发明一个实施例中，因冰箱100按照故障化霜策略运行的时长达到第一设定时长而控制冰箱100退出所述故障化霜策略后，该方法还可以包括：判断风机110是否处于故障状态；若风机110处于故障状态，则控制冰箱100按照普通化霜策略运行，运行第二设定时长后，判断风机110是否处于故障状态，若风机110仍处于故障状态，再次控制冰箱100按照故障化霜策略运行。
优选地，冰箱100再次按照故障化霜策略运行后，直到风机110处于正常状态，退出故障化霜策略。
事实上，冰箱100按照故障化霜策略运行的时长达到第一设定时长时，风机110上的冰霜会消融一部分或全部，若此时判断风机110仍处于故障状态，则说明风机110上还有一部分的冰霜。为避免冰箱100间室温度过高，此时控制冰箱100进入普通化霜策略，控制冰箱100按照普通化霜策略运行第二设定时长可使冰箱100储存足够的冷量以应对接下来冰箱100可能再次执行故障化霜策略的情况。冰箱100按照普通化霜策略运行第二设定时长时若判断风机110仍处于故障状态，由于风机110上的冰霜相对较少，再次控制冰箱100按照故障化霜策略运行后，直到风机110处于正常状态，退出故障化霜策略，从而可将冰霜尽快完全消融，使冰箱100尽快回归正常制冷状态。
图3是根据本发明一个实施例的冰箱100的控制方法的完整流程示意图。为了使本发明的上述技术方案内容更加清楚、明白，接下来，参照图3对本发明提出的冰箱100的控制方法进行更加完整、全面的阐述。参见图3所示，该方法可以至少包括如下步骤S302-S336。
步骤S302：判断冰箱100的风机是否处于故障状态；若是，执行步骤S304；若否，返回继续判断风机是否处于故障状态；
本步骤中，判断风机110是否处于故障状态包括但不限于通过以下方式：通过PWM控制输入端输入既定功率P0，风机110反馈的实际转速n与既定功率P0下的风机110既定转速N存在一定的转速差值或风机110未反馈信号，则确定风机110处于故障状态。
步骤S304：确定风机110的故障类型；
本步骤中，确定风机110的故障类型包括但不限于通过以下方式：通过PWM控制输入端输入既定功率P0后，若风机110反馈的实际转速n与既定功率P0下的风机110既定转速N存在一定的转速差值，则可确定风机110的故障类型是结霜故障；若风机110未反馈信号，则可确定风机110的故障类型是断电故障。
步骤S306：判断风机110的故障类型是否是结霜故障；若是，执行步骤S308；若否，执行步骤S310；
步骤S308：控制冰箱100按照故障化霜策略运行，m＝1；其中，m是冰 箱100按照故障化霜策略运行的次数；接下来执行步骤S312；
步骤S310：确定风机110的故障类型为断电故障，控制冰箱100按照故障报警策略运行；控制冰箱100发出报警信号；且检测冰箱100的间室的温度超过第一设定温度，控制冰箱100的压缩机140和风门150开启直至间室的温度低于第二设定温度，控制压缩机140和风门150关闭；
本步骤中，控制发出报警信号以提醒用户冰箱100的风机110出现断电故障以尽快对其维修。检测冰箱100的间室的温度超过第一设定温度，控制冰箱100的压缩机140和风门150开启直至间室的温度低于第二设定温度，控制压缩机140和风门150关闭，通过自然对流维持冰箱100间室温度从而可避免风机110出现断电故障后冰箱100间室温度波动大、影响冰箱100制冷效果。
步骤S312：控制加热装置130开启、压缩机140关闭；接下来执行步骤S314；
步骤S314：判断化霜传感器检测到的温度是否达到第三设定温度？若是，执行步骤S316；若否，继续执行加热装置130开启、压缩机140关闭；
步骤S316：控制加热装置130关闭；接下来执行步骤S318；
本步骤中，在确定风机110出现结霜故障后，控制冰箱100及时按照故障化霜策略运行，以免影响制冷效果，在化霜传感器检测到的温度达到第三设定温度后，关闭加热装置130，从而可避免造成冰箱100间室温度过高。
步骤S318：判断风机110是否处于故障状态？若是，执行步骤S320；若否，执行步骤S322；
步骤S320：判断冰箱100按照故障化霜策略运行的次数m是否大于1；若否，执行步骤S324；若是，执行步骤S326；
本步骤中，若冰箱100按照故障化霜策略运行的次数m大于1，则说明风机110上冰霜相对较少，此时则控制冰箱100一直执行故障化霜策略直至风机110处于正常状态。
步骤S322：控制冰箱100执行普通化霜策略，m＝0；
步骤S324：判断冰箱100按照故障化霜策略运行的时长是否达到第一设定时长？若否，执行步骤S326；若是，执行步骤S328；
步骤S326：控制压缩机140开启，接下来执行步骤S336；
步骤S328：判断风机110是否处于故障状态？若是，执行步骤S330； 若否，执行步骤S322；
步骤S330：控制冰箱100执行普通化霜策略第二预设时长；接下来执行步骤S332；
本步骤中，冰箱100第一次按照故障化霜策略时长达到第一预设时长且风机110处于故障状态，控制冰箱100执行普通化霜策略可避免间室温度过高，控制冰箱100按照普通化霜策略运行第二设定时长可使冰箱100储存足够的冷量以应对接下来冰箱100可能再次执行故障化霜策略。
步骤S332：判断风机110是否处于故障状态？若是，执行步骤S334；若否，执行步骤S322；
步骤S334：冰箱100按照故障化霜策略运行的次数m等于2，接下来返回步骤S308；
步骤S336：判断化霜传感器检测到的温度是否达到第四设定温度？若是，返回步骤S312；若否，继续控制压缩机140开启。
本步骤中，控制压缩机140开启直至化霜传感器检测到的温度达到第四设定温度再关闭压缩机140、加热装置130，从而可进一步避免间室温度过高。
在本发明的提供的方法中，获取冰箱100风机110的运行状态并根据运行状态识别到风机110处于故障状态后，则确定风机110的故障类型，获取冰箱100内预先配置的与故障类型对应的故障消除策略，控制冰箱100按照相应的故障消除策略运行，从而可使风机110尽快达到正常状态，避免影响冰箱100的制冷效果。
进一步地，若故障类型为断电故障，则在当检测冰箱100间室的温度超过第一设定温度时，控制冰箱100的压缩机140和风门150开启直至间室的温度低于第二设定温度，控制压缩机140和风门150关闭，从而可有效避免风机110出现故障后，冰箱100间室温度波动大。
