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。
超声辅助处理装置200至少包括托盘、超声发生器和超声换能器，其中，托盘可以设置在冷藏储物空间(或冷冻储物空间)内，用于承载待处理的食材。超声换能器可以设置在托盘的底部，超声发生器可以设置在冰箱10的背侧，与超声换能器之间电连接，通过向超声换能器提供能超声频电能，使得超声换能器发生振动，从而实现对食材的辅助腌制(或辅助冻结)。需要说明的是，超声辅助处理装置200的工作原理为本领域技术人员所习知，这里不再赘述。
发明人发现，将超声辅助处理装置200设置在冰箱10中以后，其托盘不足以承装大量的水对超声换能器进行散热，超声换能器持续振动产生的热量会经托盘传递至食材，当托盘的温度超过一定温度后，会对食材的处理品质产生影响。因此，在实际处理过程中，每隔一段时间需要关闭超声辅助处理装置200，使超声辅助处理装置200停机冷却，待温度降低以后再重新运行，如此反复，使得食材的处理周期较长，不利于提高食材的处理效率。基于此，本发明中通过获取超声辅助处理装置200的运行参数，根据运行参数动态调节超声辅助处理装置200的开机比(即，开机时间与关机时间的比率)，缩短超声辅助处理装置200的停机冷却时间，进而最大程度地缩短食材处理周期，该部分内容将在后文进行详细介绍。
图2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、温度检测装置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的过热保护方法。控制器300与超声发生器信号连接，用于向超声发生器提供控制信号，从而启停超声发生器以及超声信号的声强、频率等参数。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的运行状态，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。
本实施例的超声辅助处理装置200的过热保护方法以托盘的温度作为动态调节超声辅助处理装置200开机比的控制依据。检测托盘的温度可以通过各种温度检测装置330来实现，例如，温度传感器等。在一些优选实施例中，温度传感器可以设置在托盘的底部，本实施方式中，托盘由金属材料制成，传热性能较好。因此，温度传感器也可以设置在托盘的外周。计时装置340可以为计时器，通过计时器累计超声辅助处理装置200的运行时间，当超声辅助处理装置200总的运行时间达到食材所需的处理时间后，代表食材已经处理完成，此时可以关闭超声辅助处理装置200。
图3是根据本发明一个实施例的超声辅助处理装置200过热保护方法的示意图。该方法至少包括以下步骤S102至步骤S106。
步骤S102，以初始开机比运行超声辅助处理装置200。
该步骤中，由于初始开机比受冰箱10外部环境的温度、湿度以及冷藏储物空间内温度的影响，不同环境温度、湿度下的初始开机比不同。本实施方式中，以初始开机比为1:2进行说明，也就是开机10秒，停机20秒。
步骤S104，获取超声辅助处理装置200的运行参数，根据超声辅助处理装置200的运行参数调节超声辅助处理装置200的开机比。
步骤S106，累计超声辅助处理装置200的总处理时间，直至超声辅助处理装置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。
该步骤中，预设处理时间指的是理想条件下，食材持续处理直至处理完成的所需时间。当然，由于不同食材的预设处理时间也会存在差异，因此， 预设处理时间的具体数值可根据食材的种类自行设定。
本发明的超声辅助处理装置200的过热保护方法，首先以初始开机比运行超声辅助处理装置200，运行过程中获取超声辅助处理装置200的运行参数，然后根据超声辅助处理装置200的运行参数调节超声辅助处理装置200的开机比，累计超声辅助处理装置200的总处理时间，直至超声辅助处理装置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。本实施方式提供的过热保护方法，通过动态调整超声辅助处理装置200的开机比，缩短超声辅助处理装置200的停机冷却时间，从而能够最大程度地缩短食材处理完成所需的总时长，显著地提高了食材处理效率。
步骤S104中，超声辅助处理装置200的运行参数主要包括超声辅助处理装置200的温度，根据超声辅助处理装置200的运行参数调节超声辅助处理装置200的开机比的步骤可以是获取超声辅助处理装置200的温度，将超声辅助处理装置200的温度与第一预设温度进行比较。若超声辅助处理装置200的温度高于第一预设温度，则将超声辅助处理装置200的开机比调低以得到新的开机比。若超声辅助处理装置200的温度低于第二预设温度，则将超声辅助处理装置200的开机比调高以得到新的开机比。其中，第一预设温度为临界温度，也可以理解为超声辅助处理装置200所允许的最高运行温度，在第一预设温度以下，处理过程中基本不会对食材的品质产生不利影响。第一预设温度可以通过实验数据测得，不同食材的第一预设温度也会存在差异，第二预设温度可以低于第一预设温度3℃～15℃。
在一个可选实施例中，获取超声辅助处理装置200的温度的步骤可以是获取设置在超声辅助处理装置200外周(具体为托盘外周或底部)的温度传感器的检测值，并将检测值作为超声辅助处理装置200的温度。
步骤S106中，在累计超声辅助处理装置200的处理时间的步骤之后还可以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，则关闭超声辅助处理装置200。若否，则判断超声辅助处理装置200是否以新的开机比运行了指定循环，在超声辅助处理装置200以新的开机比运行指定循环后，再重新获取超声辅助处理装置200的温度，并将超声辅助处理装置200的温度与第一预设温度进行比较。通过控制超声辅助处理装置200以新的开机比运行指定循环能够避免频繁地调节超声辅助处理装置200的开机比，以免影响食材处理的稳定性。
可选地，累计超声辅助处理装置200的处理时间的步骤可以是在开关超声辅助处理装置200的同时开关计时器，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。
优选地，在食材处理完成，关闭超声辅助处理装置200的步骤之后，还可以在冰箱10的显示界面上显示超声辅助处理装置200处于处理完成状态，提示用户当前食材已经处理完成。
进一步地，在食材处理完成，关闭超声辅助处理装置200的步骤之后，还可以控制冰箱10发出处理完成的提示音，以便用户将处理完成的食材及时取出。
在一个优选实施例中，在以初始开机比运行超声辅助处理装置200之前，还可以判断超声辅助处理装置200内是否放置有食材，在确定食材放置到位的情况下，再执行以初始开机比运行超声辅助处理装置200，如此，可以避免在未放置食材的情况下运行超声辅助处理装置200。
具体地，判断超声辅助处理装置200内是否放置有食材的步骤可以是获取设置在超声辅助处理装置200中(具体为托盘中)的电容式传感器或探针式传感器的感测数据，然后根据感测数据判断超声辅助处理装置200中是否放置有食材。本实施方式中，感测数据具体为介电常数，由于在有水或食材的情况下以及在没有水或食材的情况下，电容式传感器及探针式传感器检测到的介电常数不同，因此可以区分超声辅助处理装置200中是否放置有食材。
图4是根据本发明一个实施例的超声辅助处理装置200过热保护方法的流程图。该方法至少包括以下步骤S202至步骤S228。
步骤S202，获取设置在超声辅助处理装置200中的电容式传感器或探针式传感器的感测数据。
步骤S204，根据感测数据判断超声辅助处理装置200中是否放置有食材，若是，执行步骤S206。
步骤S206，以初始开机比运行超声辅助处理装置200。
该步骤中，初始开机比受冰箱10外部环境的温度、湿度以及冷藏储物空间内温度的影响，不同环境温度、湿度下的初始开机比不同。本实施方式中，初始开机比以1:2为例进行说明，也就是开机10秒，停机20秒。
步骤S208，获取设置在超声辅助处理装置200外周的温度传感器的检测值，并将检测值作为超声辅助处理装置200的温度。
该步骤中，温度传感器具体可以设置在托盘的底部或托盘的外壁上。
步骤S210，判断超声辅助处理装置200的温度是否高于第一预设温度，若是，执行步骤S212，若否，执行步骤S226。
该步骤中，第一预设温度为临界温度，也可以理解为超声辅助处理装置200所允许的最高运行温度，在第一预设温度以下，处理过程中基本不会对食材的品质产生不利影响。第一预设温度可以通过实验数据测得，不同食材的第一预设温度也会存在差异。
步骤S212，将超声辅助处理装置200的开机比调低，以得到新的开机比。
该步骤中，可以通过缩短开机时间的方式或延长停机时间的方式将超声辅助处理装置200的开机比调低。
步骤S214，累计超声辅助处理装置200的处理时间。
步骤S216，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S218，若否，执行步骤S224。
该步骤中，预设处理时间指的是理想条件下，食材持续处理直至处理完成的所需时间。当然，由于不同食材的预设处理时间也会存在差异，因此，预设处理时间的具体数值可根据食材的种类自行设定。
步骤S218，关闭超声辅助处理装置200。
步骤S220，冰箱10的显示界面上显示食材已经处理完成。
步骤S222，冰箱10发出提示音，以提醒用户将处理完成的食材时取出。
步骤S224，判断超声辅助处理装置200是否以新的开机比运行了指定循环，若是，返回步骤S208，若否，返回步骤S214。
该步骤中，通过控制超声辅助处理装置200以新的开机比运行指定循环能够避免频繁地调节超声辅助处理装置200的开机比，以免影响食材处理的稳定性。
步骤S226，判断超声辅助处理装置200的温度是否低于第二预设温度，若是，执行步骤S228，若否，执行步骤S214。
该步骤中，第二预设温度可以低于第一预设温度3℃～15℃。
步骤S228，将超声辅助处理装置200的开机比调高，以得到新的开机比，然后执行步骤S214。
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的过热保护方法能够在不影响食材品质的前提下，有效减少食材处理过程中的停机冷却时间，从而缩短食材处理周期，提高食材的处理效率。
在实际应用中，在采用超声辅助处理装置200对食材进行处理的过程中，还可以将冷藏储物空间内的温度调低(例如，冷藏储物空间内的初始温度为9℃，在采用超声辅助处理装置200进行食材的处理时，可以将冷藏储物空间内的温度调低为0℃～3℃)，从而提高超声辅助处理装置200的散热效果，使得超声辅助处理装置200尽可能地在开机比较高的情况下运行，缩短超声辅助处理装置200的停机冷却时间，进一步缩短食材的处理周期，提高食材的处理效率。
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。
