根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
通过阅读下文优选实施方式的详细描述，各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的，而并不认为是对本发明的限制。而且在整个附图中，用相同的参考符号表示相同的部件。在附图中：
图1是根据本发明一个实施例的冰箱的结构示意图；
图2是根据本发明一个实施例的超声辅助处理装置的结构示意图；
图3是根据本发明一个实施例的冰箱的示意框图；
图4是根据本发明一个实施例的超声辅助处理装置的故障监测方法的示意图；以及
图5是根据本发明一个实施例的超声辅助处理装置的故障监测方法的流程图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
为解决上述问题，本发明提供了一种冰箱10。图1是根据本发明一个实 施例的冰箱10的结构示意图。该冰箱10一般性地可包括箱体100，箱体100内形成有一个或多个储物间室110，储物间室110根据制冷温度可以被配置形成冷藏储物空间、冷冻储物空间、变温储物空间等。具体地，储物间室110的数量，功能、布局方式可以根据需求进行配置。
本发明的冰箱10还可以进一步地包括超声辅助处理装置200(图1中未示出)，本实施方式中，超声辅助处理装置200设置在冰箱10的冷藏储物空间内，当然，在一些情况下，超声辅助处理装置200也可以设置在冷冻储物空间内或变温储物空间内，超声辅助处理装置200的功能包括但不限于辅助腌制、辅助冻结等。超声辅助处理装置200可以通过抽屉的形式搭载于冷藏储物空间内或直接放置在冷藏储物空间内。
图2是根据本发明一个实施例的超声辅助处理装置200的结构示意图。参照图2，超声辅助处理装置200至少包括超声发生器230、多个第一超声换能器210以及一个第二超声换能器220，其中，超声发生器230可以设置在冰箱10的背侧，用于发送驱动信号。多个第一超声换能器210并联设置，分别接收由超声发生器230发送的超声信号，从而产生对目标食材的超声振动。第二超声换能器220不用于接收超声发生器230发送的驱动信号，而是用于由多个第一超声换能器210产生的超声振动形成实际感生电压。
进一步地，超声辅助处理装置200还包括设置在储物间室110内的托盘240，本实施方式中，托盘240由不锈钢金属材料制成。第二超声换能器220可以设置在托盘240底部外侧的中央，多个第一超声换能器210可以围绕第二超声换能器220设置在托盘240底部外侧的四周，以便多个第一超声换能器210在工作过程中产生的超声振动能够通过托盘240较为充分地传递至第二超声换能器220。
在一个可选实施例中，第一超声换能器210可以设置有四个，四个第一超声换能器210在托盘240的底部外侧阵列排布，第二超声换能器220位于四个第一超声换能器210的中心位置处且固定至托盘240。
本实施方式中，超声发生器230上连接有第一接线231和第二接线232，各第一超声换能器210的两个接点分别与第一接线231和第二接线232连接，也即四个第二超声换能器220之间并联设置、独立工作。
图3是根据本发明一个实施例的冰箱10的示意框图。进一步地，该冰箱10还可以设置有控制器300、采集装置330、计时装置340等。
控制器300包括存储器320以及处理器310，存储器320内存储有控制程序321，控制程序321被处理器310执行时用于实现本实施例的超声辅助处理装置200的故障监测方法。控制器300与超声发生器230的电源信号连接，通过电源启停超声发生器230。控制器300可以集成于冰箱10的主控板上，也可以邻近超声发生器230单独设置。控制器300进一步可以与冰箱10的主控装置信号连接，向主控装置提供超声发生器230的工作状态，并接收于来自主控装置的控制命令。
控制器300可以由各种具有一定数据处理能力的器件实现，在一个典型的配置中，控制器300可以包括存储器320、处理器310、输入/输出接口等。
采集装置330可以集成在冰箱10的电脑控制板上，并且与第二超声发生器230之间电连接，用于采集第二超声发生器230的实际感生电压。计时装置340用于累计超声辅助处理装置200的处理时间，以便在超声辅助处理装置200的处理时间到达食材的预设处理时间后，及时关闭超声辅助处理装置200。
可以理解，第一超声换能器210由压电陶瓷制成，当其出现故障时，例如开裂，若继续工作，则会出现更大范围的开裂，从而导致该第一超声换能器210报废或发生危险。因此，为解决此问题，本实施方式通过增设第二超声换能器220，利用第二超声换能器220产生的感生电压来判断多个第一超声发生器230中是否有存在故障的，从而能够及时地对有故障的第一超声换能器210进行维修或更换。
图4是根据本发明一个实施例的超声辅助处理装置200的故障监测方法的示意图。参照图4，该故障监测方法至少包括以下步骤S102至步骤S106。
步骤S102，获取第二超声换能器220产生的实际感生电压。
步骤S104，将实际感生电压与标准感生电压进行比较。
步骤S106，若实际感生电压小于标准感生电压，则切断超声发生器230的电源。
需要说明的是，实际感生电压与标准感生电压的大小关系仅存在以下两种情况：第一种，当多个第一超声换能器210均处于正常工作状态时，实际感生电压等于标准感生电压；第二种，当多个第一超声换能器210中的至少之一出现故障问题时，实际感生电压小于标准感生电压，且出现故障问题的第一超声换能器210的数量越多，实际感生电压越小。由于工作过程中第一 超声换能器210的振幅不变，因此，不会出现实际感生电压大于标准感生电压的情况。若将第一超声换能器210的振幅调大，则相应地也会有新的标准感生电压作为衡量标准。
本发明的超声辅助处理装置200的故障监测方法，在发现多个第一换能器工作过程会使第二超声换能器220产生实际感生电压的情况下，通过将实际感生电压与标准感生电压进行比较，当出现实际感生电压小于标准感生电压时，则可以说明第一换能器中有存在故障的问题，此时，通过自动切断超声发生器230的电源，使第一换能器停止工作，从而有效避免了有故障的第一换能器发生更大范围的损坏。
上文步骤S102中，获取第二超声换能器220产生的实际感生电压的步骤可以是获取采集装置330的采样值，并将采样值作为第二超声换能器220产生的实际感生电压。采集装置330可以集成在冰箱10的电脑控制板上，并与第二超声换能器220电连接。
标准感生电压是根据第二超声换能器220在多个第一超声换能器210均正常工作时所产生的电压值进行设定，且在各个第一超声换能器210的振幅同时增大或减少时，相应地，标准感生电压的电压值也会随之增大或减小。
上文步骤S106中，在切断超声发生器230的电源的步骤之后，还可以根据实际感生电压与标准感生电压的差值生成故障代码，故障代码可以用于表示出现故障的第一超声换能器210的数量。例如，第一超声换能器210的数量为四个，四个第一超声换能器210均处于正常工作状态时，标准感生电压为2.5V。若有一个第一超声换能器210出现故障，第二超声换能器220产生的实际感生电压为2.0V；若有两个第一超声换能器210出现故障，第二超声换能器220产生的实际感生电压为1.5V；若有三个第一超声换能器210出现故障，第二超声换能器220产生的实际感生电压为1V；若四个第一超声换能器210全部出现故障，第二超声换能器220产生的实际感生电压为0V。由于实际感生电压与标准感生电压的不同差值生成的故障代码不同，相应地，表示出现故障的第一超声换能器210的数量也就不同，因此可以有效区分。
进一步地，在根据实际感生电压与标准感生电压的差值生成故障代码的步骤之后，还可以在冰箱10的显示界面上显示故障代码，并控制冰箱10的蜂鸣器发出故障提示音，以便工作人员能够及时了解故障情况，并对出现故 障的第一超声换能器210进行维修或更换。
在一个优选实施例中，在将实际感生电压与标准感生电压进行比较的步骤之后，若实际感生电压等于标准感生电压，即各个第一超声换能器210均处于正常工作状态时，则累计超声辅助处理装置200的总处理时间，当超声辅助处理装置200的总处理时间到达预设处理时间后，关闭超声辅助处理装置200。这里的预设处理时间指的是食材在持续被处理直至处理完成的所需时间，当超声辅助处理装置200的总处理时间到达预设处理时间时，表明食材基本已经处理完成，此时，可以关闭超声辅助处理装置200。
累计超声辅助处理装置200的总处理时间的步骤可以是在运行超声辅助处理装置200的同时开启计时器，获取计时器总的计时时间，将计时器总的计时时间作为超声辅助处理装置200的总处理时间。此种方式较为简单方便，易于操作。
图5是根据本发明一个实施例的超声辅助处理装置200的故障监测方法的流程图。参照图5，该故障监测方法至少包括以下步骤S202至步骤S220。
步骤S202，获取采集装置330的采样值。
该步骤中，采集装置330可以集成在冰箱10的电脑控制板上，并与第二超声换能器220之间电连接。
步骤S204，将采样值作为第二超声换能器220产生的实际感生电压。
步骤S206，判断实际感生电压是否小于标准感生电压，若是，执行步骤S208，若否，执行步骤S214。
该步骤中，实际感生电压与标准感生电压的大小关系仅存在以下两种情况：第一种，当多个第一超声换能器210均处于正常工作状态时，实际感生电压等于标准感生电压；第二种，当多个第一超声换能器210中的至少之一出现故障问题时，实际感生电压小于标准感生电压，且出现故障问题的第一超声换能器210的数量越多，实际感生电压越小。由于工作过程中第一超声换能器210的振幅不变，因此，不会出现实际感生电压大于标准感生电压的情况。若将第一超声换能器210的振幅调大，则相应地也会有新的标准感生电压作为衡量标准。
步骤S208，切断超声发生器230的电源。
步骤S210，根据实际感生电压与标准感生电压的差值生成故障代码。
该步骤中，实际感生电压与标准感生电压的不同差值生成的故障代码不 同，不同的故障代码用于表示不同数量的第一超声换能器210出现故障。
步骤S212，在冰箱10的显示界面上显示故障代码，并控制冰箱10的蜂鸣器发出故障提示音。
该步骤中，通过蜂鸣器发出故障提示音可以提醒工作人员及时对出现故障的第一超声换能器210进行维修或更换。
步骤S214，清除显示界面上显示的故障代码。
该步骤中，需要说明的是，故障代码是在多个超声换能器中有出现故障的情况下生成的，以便工作人员根据故障代码进行维修或更换，待维修或更换完成后，若再次监测时未发现第一超声换能器210出现故障，则清除显示界面上显示的故障代码。若前一次监测过程中未生成故障代码，则本次执行过程中显示界面上不会显示故障代码也无需清除，可跳过步骤S214直接执行步骤S216。
步骤S216，累计超声辅助处理装置200的总处理时间。
步骤S218，判断超声辅助处理装置200的总处理时间是否到达预设处理时间，若是，执行步骤S220，若否，返回步骤S202。
该步骤中，预设处理时间指的是食材在持续被处理直至处理完成的所需时间，当超声辅助处理装置200的总处理时间到达预设处理时间时，表明食材基本已经处理完成，此时，关闭超声辅助处理装置200即可。
步骤S220，关闭超声辅助处理装置200，停止通过采集装置330获取采样值。
经过对试制样品的实际使用，本实施例的冰箱10及其超声辅助处理装置200的故障监测方法，能够及时发现存在故障的第一超声换能器210，并立即切断超声发生器230的电源，避免因第一超声换能器210开裂而发生危险。
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。
