Description

一种冰箱及其超声辅助处理装置的过热保护方法 技术领域
本发明涉及冰箱技术领域，特别是涉及一种冰箱及其超声辅助处理装置的过热保护方法。
背景技术
目前冰箱对于储物性能的评价已经并非简单的延长储藏时间，有些用户对某些辅助功能(例如腌制、清洗等)的实现也提出了需求。
现有技术中，超声辅助处理装置在工业领域应用较为广泛，在工业领域中，超声辅助处理装置主要用于食材的清洗，其内部承装有大量的水，在清洗过程中，大量的水可以起到很好的散热作用，从而可以较好地抑制超声辅助处理装置的温度处于较为理想的温度范围。
然而将超声辅助处理装置应用于冰箱内以后，超声辅助处理装置中难以承装大量的水，容易导致超声辅助处理装置的温度过高，进而导致食材的品质受到不利影响，因此还有待改善。

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。
由于超声辅助处理装置200设置在冰箱10中以后，其托盘内不足以承装大量的水，超声换能器持续振动会产生较多热量，热量通过托盘向上传递至食材会对食材的品质产生不利影响。因此，为避免此问题，本发明中对超声辅助处理装置200的运行方式进行特殊控制，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和计时装置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。
本实施例的过热保护方法以超声辅助处理装置200的单次启动时长作为控制依据，保证在处理过程中，超声辅助处理装置200的温度不会对食材的品质产生影响。计时装置340可以为计时器，通过计时器能够较为方便、准确地测定超声辅助处理装置200的处理时间以及累计超声辅助处理装置200的总处理时间。
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S110。
步骤S102，启动超声辅助处理装置200。
步骤S104，判断超声辅助处理装置200本次启动后的处理时间是否到达预设的单次启动时长。
该步骤中，单次启动时长可以根据超声辅助处理装置200从初始温度上升至允许的最高温度的所需时间进行设定。超声辅助处理装置200允许的最高温度是指临界温度，超声辅助处理装置200在该温度以下运行不会对食材的品质产生影响。
步骤S106，若是，判断超声辅助处理装置200的累计处理时间是否到达预设处理时间。
该步骤中，预设处理时间指的是理想状态下，持续处理食材直至食材处理完成的所需时间。
步骤S108，若超声辅助处理装置200的累计处理时间到达预设处理时间，则关闭超声辅助处理装置200。
步骤S110，若超声辅助处理装置200的累计处理时间未到达预设处理时间，则控制超声辅助处理装置200停机预设的暂停时长后，返回至步骤S102，重新启动超声辅助处理装置200。
本发明的超声辅助处理装置200的保护方法，首先启动超声辅助处理装置200，然后判断超声辅助处理装置200本次启动后的处理时间是否到达预设的单次启动时长，若是，接着判断超声辅助处理装置200的累计处理时间 是否到达预设处理时间，若超声辅助处理装置200的累计处理时间到达预设处理时间，则关闭超声辅助处理装置200，若超声辅助处理装置200的累计处理时间未到达预设处理时间，则控制超声辅助处理装置200停机预设的暂停时长后，重新启动超声辅助处理装置200。由此可见，本实施方式提供的过热保护方法，通过控制超声辅助处理装置200的单次启动时长，使超声辅助处理装置200以开机比(即开机时间与关机时间的比率)的方式周期运行，从而能够避免因超声辅助处理装置200的温度过高而对食材的处理品质产生不利影响。
步骤S106中，在判断超声辅助处理装置200的累计处理时间是否到达预设处理时间的步骤之前还可以是先根据待处理食材的种类从预存的对应关系表中获取食材处理完成的所需时间，然后将食材处理完成的所需时间作为预设处理时间。由于不同食材处理完成的所需时间会存在一定的差异，因此，本实施方式中，对食材处理完成所需时间的具体数值不做限制。
步骤S110中，预设的暂停时长根据超声辅助处理装置200所允许的最高温度下降至初始温度的所需时间进行设定。本实施方式中，控制超声辅助处理装置200停机预设的暂停时长的步骤可以是关闭超声辅助处理装置200，判断超声辅助处理装置200的停机时间是否到达预设的暂停时长，若是，则重新开启所述超声辅助处理装置200，若否，则继续等待，直至所述超声辅助处理装置200的停机时间到达预设的暂停时长。
在一些实施例中，在控制超辅助处理装置200停机预设的暂停时长的过程中，可以对超声辅助处理装置200进行快速降温，使其在短时间内从最高温度下降至初始温度，采取的降温措施包括但不限于将冷藏储物空间的温度调至最低温度，以提高超声辅助处理装置200的散热效果。
实际应用中，例如，在冷藏储物空间的温度为9℃、超声辅助处理装置200的开机比为1:2的情况下，超声辅助处理装置200以开机10S、停机20S的方式周期运行，一段时间后其温度最终会维持25℃左右，而不会超过允许的最高温度30℃，但此种方式停机时间过长，严重影响食材的处理效率。本实施方式中，可以使超声辅助处理装置200以开机10S、停机10S的方式周期运行，从而可以缩短停机时长，但也因此会导致超声辅助食材处理装置200的温度逐渐升高至30℃，此时，通过对超声辅助处理装置200进行快速降温，可以使其温度再次回到初始温度，如此，能够最大程度地缩短超声辅助处理 装置200的停机时间，进而缩短食材的处理周期，提高处理效率。
在一个可选实施例中，判断超声辅助处理装置200本次启动后的处理时间是否到达预设的单次启动时长的步骤可以是在启动超声辅助处理装置200的同时开启计时器，然后获取计时器的计时时间，判断计时时间是否到达预设的单次启动时长，操作较为方便简单。
优选地，在超声辅助处理装置200的累计处理时间到达预设处理时间，关闭超声辅助处理装置200的步骤之后，还可以控制冰箱10在其显示界面上显示超声辅助处理装置200当前处于处理完成状态，从而避免将食材已经处理完成误认为超声辅助处理装置200在停机冷却。
进一步地，在超声辅助处理装置200的累计处理时间到达预设处理时间，关闭超声辅助处理装置200的步骤之后，还可以通过冰箱10发出处理完成的提示音，以便提醒用户将处理完成的食材及时取出。
在一个优选实施例中，在启动超声辅助处理装置200的步骤之前，还包括：判断超声辅助处理装置200内是否放置有食材，若是，执行启动超声辅助处理装置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中的电容式传感器或探针式传感器的感测数据，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。
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S222。
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，若否，返回至步骤S202。
步骤S206，启动超声辅助处理装置200。
步骤S208，判断超声辅助处理装置200本次启动后的处理时间是否到达预设的单次启动时长，若是，执行步骤S210，若否，返回继续执行步骤S208。
该步骤中，单次启动时长可以根据超声辅助处理装置200从初始温度上升至允许的最高温度的所需时间进行设定。超声辅助处理装置200允许的最高温度是指临界温度，超声辅助处理装置200在该温度以下运行不会对食材 的品质产生影响。
步骤S210，根据待处理食材的种类从预存的对应关系表中获取食材处理完成的所需时间。
步骤S212，将食材处理完成的所需时间作为预设处理时间。
步骤S214，判断超声辅助处理装置200的累计处理时间是否到达预设处理时间，若是，执行步骤S216，若否，执行步骤S222。
步骤S216，关闭超声辅助处理装置200。
步骤S218，冰箱10的显示界面上显示食材已经处理完成。
步骤S220，冰箱10发出提示音，以提醒用户将处理完成的食材及时取出。
步骤S222，控制超声辅助处理装置200停机预设的暂停时长，返回步骤S206。
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的过热保护方法通过控制超声辅助处理装置200的单次启动时长，能够有效避免因超声辅助处理装置200(具体为托盘)的温度过高而导致食材的品质受到不利影响。
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。
