Description

冰箱的故障提示方法 技术领域
本发明涉及制冷家电领域，尤其涉及一种冰箱的故障提示方法。
背景技术
近年来，冰箱逐渐趋近于智能化。例如在门体上设置显示屏，给用户提供便利的调控方式，还能显示冰箱的运行信息，并且在冰箱出现故障时，会通过显示屏显示故障代码、或故障信息、或故障原因等故障信息，用户可以通过电话向维修中心汇报故障信息，维修人员根据故障信息携带需要的配件及工具上门维修。由此可见，设置有显示屏的冰箱给用户使用和售后维护均带来了极大的方便。
但是在特殊的应用场合，仍然存在大批量的无显示屏的冰箱。目前无显示屏的冰箱到用户家里之后，如果出现故障了又没有直观的故障判断方法，只能通过专业的售后人员上门检查，查清原因后，再回去准备配件工具等，二次上门维修，浪费了大量的人力和时间，也影响了用户使用。
有鉴于此，有必要提供一种新的冰箱的故障提示方法，以解决上述问题。
发明内容

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本发明一较佳实施例的冰箱的故障提示方法的流程示意图；
图2为本发明另一较佳实施例的冰箱的故障提示方法的流程示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明 保护的范围。
请参阅图1～图2所示，本发明旨在针对无显示屏的冰箱提供一种冰箱的故障提示方法，该方法不依赖于显示屏获取信号和发出信号，但是也可以用于有显示屏的冰箱。
所述冰箱的故障提示方法包括如下步骤：S1获取到冰箱故障自检信号后，进入故障自检提示模式，冰箱运行故障自检程序；S2判断冰箱是否有故障，若是，则发出故障提示信号；若无，则退出故障自检提示模式。
具体地，步骤S1包括：获取到冰箱上的工作元件被执行特定动作后进入故障自检提示模式。其中，所述工作元件为所述冰箱通用的、既有的工作元件，例如：冰箱门体、主控板、冷藏室照明灯等，无需额外增加显示屏等结构提高冰箱的成本，即可进入故障自检提示模式。
一实施例中，通过冰箱门体被执行特定动作进入故障自检提示模式。所述“工作元件被执行特定动作”包括在第一预设时间段内开关门N次。
本发明充分考虑到儿童、青少年、中年、老年人等不同用户群体的行动敏捷性，将所述预设时间段设定为N秒～2N秒，大家可以在规定的时间内完成规定的开关门次数。
并且，本发明充分考虑到用户可能会因各种原因在短时间内多次开门拿东西，将所述N设定为3～6，避免用户因为正常使用或误操作而频繁进入到故障自检提示模式。
另一实施例中，通过冷藏室的照明灯被执行特定动作进入故障自检提示模式。所述“工作元件被执行特定动作”包括在第二预设时间段内开关灯N’次。
所述第二预设时间段设定为N’秒～1.5N’秒，大家可以在规定的时间内完成规定的照明灯开关次数。和/或，所述N’设定为3～6。
另一实施例中，通过冰箱的主控板被执行特定动作进入故障自检提示模式。
所述“工作元件被执行特定动作”包括但不限于：按下冰箱主控板上的TEST按键，或按住冰箱主控板上的TEST按键长达第三预设时间段，所述第三预设时间段为3秒～5秒；或对冰箱主控板进行掰边。
进一步地，发明人通过对冰箱各个部件进行分析，按照其发生故障的概率、对冰箱工作的影响等，设定各部件故障检测的优先级顺序为：化霜故障、冷冻风机故障、冷藏风机故障、冷冻电位器故障、冷藏电位器故障、化霜传感器故障、冷冻传感器故障、冷藏传感器故障、环温传感器故障。
冰箱运行故障自检程序时，从前往后依次检测各个故障。
步骤S2中，判断冰箱是否有故障，并输出故障提示信号包括但不限于以下几种：
一实施例中，检测出其中一个故障即输出有故障的信号。例如，冰箱检测到冷冻风机有故障后，就不再继续检测其他部件，直接输出有故障的信号。此时，需要在解除当前故障后，再次进入故障自检提示模式，判断冰箱是否还有故障。该方法可以避免因为当前故障对后续部件的检测出现误检的情况。
另一实施例中，冰箱运行故障自检程序时，在所有的部件按照上述优先级顺序自检完成后，才输出是否有故障的信号。可以一次性检测出多个故障，避免维修人员多次上门维修，节约人力成本。
进一步地，当冰箱存在至少两个故障时，发出一个故障提示信号后，给出仍有故障的故障继续提示信号，退出故障自检提示模式。此时，需要用户或工作人员根据当前故障是否会导致对后续部件的检测造成故障的误判，判断是否要解除当前故障后再进入下一轮的故障自检提示模式，还是直接进入下一轮的故障自检模式。
或，冰箱存在至少两个故障时，发出一个故障提示信号后，间隔第四预设时间段后，继续发出下一个故障提示信号。所述第四预设时间段通常为3秒～5秒。
进一步地，基于上述任意一种实施例，依次发出所有故障提示信号后，发出无故障提示信号并退出故障自检提示模式。
另外，若自检程序结束后发现无故障，则发出无故障提示信号后退出故障自检提示模式。一实施例中，所述无故障提示信号为蜂鸣器发出的开门无效音。
表1通过蜂鸣器针对不同故障发出不同故障提示音。
Figure PCTCN2022102156-appb-000001
步骤S2中通过冰箱上的工作元件发出故障提示信号。同样地，所述工作元件为所述冰箱通用的、既有的工作元件，例如：主控板、冷藏室照明灯等，无需额外增加显示屏等结构提高冰箱的成本，即可给用户输出故障信号。
一实施例中，通过冰箱的蜂鸣器发出故障提示音，给出故障信号。且针对不同的故障，蜂鸣器发出不同的故障提示音；或，针对不同的故障，蜂鸣器发出不同次数的故障提示音；或，针对不同的故障，蜂鸣器发出不同的故障提示音，且故障提示音的次数不同。具体实施例可参考表1。
冰箱运行故障自检程序时，从前往后依次检测如下故障：化霜故障、冷冻风机故障、冷藏风机故障、冷冻电位器故障、冷藏电位器故障、化霜传感器故障、冷冻传感器故障、冷藏传感器故障、环温传感器故障。
当检测出其中一个故障时，即停止继续自检，通过蜂鸣器发出与故障对应的故障提示音。
或者，在所有的部件自检完成后，通过蜂鸣器依次输出与所有故障对应的故障提示音。
具体地，冰箱存在至少两个故障时，蜂鸣器发出一个故障提示音后，给出仍有故障的故障继续提示音，退出故障自检提示模式。或，冰箱存在至少两个故障时，蜂鸣器发出一个故障提示音后，间隔第四预设时间段后，继续发出下一个故障提示音，所述第四预设时间段为3秒；并在依次发出与所有故障对应的故障提示音后，发出无故障提示音并退出故障自检提示模式。
表2通过照明灯针对不同故障发出不同故障提示光。
Figure PCTCN2022102156-appb-000002
另一实施例中，通过冰箱冷藏室的照明灯发出故障提示光给出故障提示，且不同的故障对应不同的故障提示光。
具体地，针对不同的故障，照明灯发光的时长不同。或，针对不同的故障，照明灯闪烁次数 不同；或，针对不同的故障，照明灯发出不同颜色的光。具体实施例可参考表2。
当然，所述故障提示光也可以为照明灯发光的时长、照明灯的闪烁次数、照明灯的发光颜色中的任意两种的组合。
冰箱运行故障自检程序时，从前往后依次检测如下故障：化霜故障、冷冻风机故障、冷藏风机故障、冷冻电位器故障、冷藏电位器故障、化霜传感器故障、冷冻传感器故障、冷藏传感器故障、环温传感器故障。
当检测出其中一个故障时，即停止继续自检，通过照明灯参考表2发出与故障对应的故障提示光。
或者，在所有的部件自检完成后，通过照明灯参考表2依次输出与所有故障对应的故障提示光。
具体地，冰箱存在至少两个故障时，照明灯发出一个故障提示光后，给出仍有故障的故障继续提示光，退出故障自检提示模式。或者，冰箱存在至少两个故障时，照明灯发出一个故障提示光后，间隔第四预设时间段后，继续发出下一个故障提示光，所述第四预设时间段为3秒；并在依次发出与所有故障对应的故障提示光后，发出无故障提示光并退出故障自检提示模式。
进一步地，基于上述任意实施例，为了防止用户或维修任何误判，针对每次故障都发出两次以上的故障信号后再退出，两次之间的间隔时间可以为5秒，但是与先后发出两个故障对应的故障信号的间隔时间不同。
上述步骤S1的任意一种方案可以与上述步骤S2的任意一种方案配合使用，具体实施例可参考图1和图2所示。
综上所述，本发明的冰箱的故障提示方法，在冰箱有故障时，则通过冰箱上的工作元件发出故障提示信号。工作元件为冰箱通用的、既有的工作元件，无需额外增加显示屏等结构提高冰箱的成本，即可提示故障，对用户和维修人员友好。

上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本 发明的保护范围之内。
