一种冰箱 技术领域
本发明涉及冷藏冷冻设备领域，特别是涉及一种冰箱。
背景技术
目前，随着生活水平的提高，人们对冰箱的评价已并非局限于储物性能，为满足用户的需求，现有技术中出现了较多改进方案，例如，将超声波技术结合在冰箱中，从而对食材进行超声清洗、超声泡发、超声冷萃等。由于市面上的超声装置通常为1个超声发生器对应1套超声换能器，限制了超声装置的应用场景。冰箱外部也会有类似于超声处理的需求，而超声装置固定在冰箱内取用很不方便，箱门长时间打开带来的电耗及冰箱内温度波动较大。因此，还有待于改善。
发明内容

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3是根据本发明一个实施例的冰箱的侧视图。
图4是根据本发明一个实施例的第二换能振动装置的安装结构示意图；
图5是从上方观察时第二换能振动装置的安装结构示意图；
图6是根据本发明一个实施例的超声发生器与第一超声换能器、第二超声换能器的连接结构示意图。
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。
图1是根据本发明一个实施例的冰箱的结构示意图。参照图1至图6，该冰箱一般性地可包括箱体100，箱体100的内部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。
特别地，该冰箱还包括第一换能振动装置210、第二换能振动装置220和超声发生器300。第一换能振动装置210可以设置在箱体100的外侧，第二换能振动装置220可以设置在储物间室110内，超声发生器300分别与第一换能振动装置210、第二换能振动装置220连接，配置成用于产生超声信号，并选择性地将超声信号传输至第一换能振动装置210或第二换能振动装置220，从而驱动第一换能振动装置210或第二换能振动装置220对待处理的食材进行超声处理。
本发明实施例的冰箱，由于其箱体100的内外分别设置有第一换能振动装置210和第二换能振动装置220，超声发生器300分别与第一换能振动装置210和第二换能振动装置220连接。因此，通过选择性地将超声发生器300产生的超声信号传输至第一换能振动装置210或第二换能振动装置220，可以利用第一换能振动装置210在箱体100的外侧对无低温要求的食材进行超声处理，利用第二换能振动装置220在储物间室110内对有低温要求的食材进行超声处理。如此，可以实现冰箱内外使用的便利性，可避免重复开关冰箱门产生的电能损耗以及储物间室110内部的温度波动。
具体地，第一换能振动装置210可包括底座211和第一超声换能器212。底座211可翻折地设置在箱体100的外壁，其具有翻转至水平位置时的工作状态和折叠至竖直位置时的收纳状态。超声换能器设置在底座211内，配置成受控地产生高频振动，并将高频振动向底座211的顶部传递。通过将底座211可翻折地设置在冰箱的外壁，当需要在冰箱外侧对食材进行超声处理时，可以将底座211翻折至水平位置，以承载待处理的食材。当处理完成后，可以将底座211折叠至竖直位置，以对底座211进行收纳，防止用户在冰箱附近走动时与底座211发生磕碰，避免底座211碰伤用户或底座211自身损坏。
在一些实施例中，底座211可以是通过翻板合页与箱体100的外壁翻转连接，也可以是通过铰接轴与箱体100的外壁翻转连接。当采用铰接轴时，应在底座211翻转至水平位置和竖直位置时对底座211进行限位，防止底座211自由转动。
进一步地，第一换能振动装置210还可以包括盒式容器213，盒式容器213的上端为敞口，其可移除地搁置在底座211上。由于将食材直接放置在底座211上进行处理，容易使底座211的表面沾染脏污，清理起来较为不便。因此，通过设置的盒式容器213来承载食材，盒式容器213可移除地搁置在 底座211上，在处理完成后，有利于取下盒式容器213进行清洁。
本实施方式中，盒式容器213的底面与底座211的顶面相适配，配置成在盒式容器213搁置在底座211上时，盒式容器213的底面与底座211的顶面相贴合。由于超声在空气中传递时会发生较大损耗，因此，需要保证盒式容器213在放置在底座211上以后，盒式容器213的底面与底座211的顶面相贴合，两者之间的缝隙应尽可能地小，以减少超声损耗，提高超声传递效率，保证超声作用效果。
在一个可选实施例中，箱体100的外壁向内凹陷形成有收纳槽101，收纳槽101配置成在底座211折叠至竖直位置时容纳底座211，以使底座211的前表面至少不超出箱体100的外壁表面。优选地，在底座211折叠至竖直位置时，底座211的前表面与箱体100的外壁表面基本齐平，保证箱体100外观的美观性。
具体地，第二换能振动装置220可包括第二超声换能器221、变幅杆222和振动头223，变幅杆222的上下两端分别与第二超声换能器221和振动头223固定连接。可以理解，变幅杆222能够显著地增大振动头223的振动幅度，提高超声作用效率，但也由此会使振动头223产生大量的热量，从而导致待处理的食材温度升高。由于第二换能振动装置220设置在储物间室110内，而储物间室110提供的低温环境能够持续地抵消热量，从而实现对有低温要求或常温易腐败变质的食材进行超声处理。例如，在利用第二换能振动装置220在储物间室110内进行冷萃中药或冷萃咖啡时，可以充分快速地完成功效或者风味物质的提取，作用效果较为显著，并且储物间室110持续地提供冷量，可以最大程度地保留活性物质及呈味物质。
在一个可选实施例中，储物间室110的内壁设置有连接组件400，连接组件400可包括第一连接板410和第二连接板420，其中第一连接板410的一端具有两个夹臂411，两个夹臂411用于从两侧对第二超声换能器221进行抱紧固定，第一连接板410的另一端具有两个上下布置的卡勾412。第二连接板420固定至储物间室110的内壁，其上设置有卡位区，卡位区内具有两个上下布置的卡口421，并且第一连接板410的两个卡勾412与第二连接板420的两个卡口421配置成：在两个卡勾412对应勾挂在两个卡口421内时，第二超声换能器221通过第一连接板410悬置在储物间室110内。通过此种方式可以较为方便地将第二超声换能器221以及变幅杆222和振动头 223悬置在储物间室110的内壁，易于拆装。
进一步地，第二连接板420在储物间室110的内壁沿竖直方向延伸设置，卡位区在第二连接板420等间距地设置有多个。通过将第二连接板420勾挂在不同高度的卡位区内，可以上下调整振动头223的位置，从而使振动头223能够适应不同高度的载物容器，也就是说，振动头223能够伸进不同高度的载物容器中，对载物容器内的食材进行超声处理。
需要说明的是，由于超声波具有促进腌制液快速被肉类吸收的作用，但是温度过高会导致微生物的快速繁殖，带来食品安全问题。而本实施方式的盒式容器213不仅可以在冰箱外侧的底座211上使用，也可以作为承载肉类的腌制容器放置在储物间室110内部使用，第二换能振动装置220的振动头223伸进至腌制液中即可。
在一个优选实施例中，冰箱还可以包括选择开关500，选择开关500具有第一开关位510和第二开关位520，当第一开关位510开启时，超声发生器300与第一换能振动装置210(具体为第一超声换能器212)导通，当第二开关位520开启时，超声发生器300与第二换能振动装置220(具体为第二超声换能器221)导通。选择开关500的设置可供用户灵活选择第一换能振动装置210或第二换能振动装置220，操作较为简单方便。
考虑到超声频率会影响到食材的处理效果，不同食材所需的最佳超声频率一般不同，为解决此问题，本实施方式中的冰箱还可以包括功率调节装置600，与超声发生器300电连接。在实际应用中，根据食材的种类查找出该类食材的最佳超声频率，然后利用功率调节装置600将超声发生器300的功率调整至最佳超声频率，从而使食材达到较佳地处理效果。
根据上述中任意一个可选实施例或多个可选实施例的组合，本发明实施例能够达到如下有益效果：
本发明实施例的冰箱，由于其箱体100的内外分别设置有第一换能振动装置210和第二换能振动装置220，超声发生器300分别与第一换能振动装置210和第二换能振动装置220连接。因此，通过选择性地将超声发生器300产生的超声信号传输至第一换能振动装置210或第二换能振动装置220，可以利用第一换能振动装置210在箱体100的外侧对无低温要求的食材进行超声处理，利用第二换能振动装置220在储物间室110内对有低温要求的食材进行超声处理。如此，可以实现冰箱内外使用的便利性，可避免重复开关冰 箱门产生的电能损耗以及储物间室110内部的温度波动。
进一步地，本发明的冰箱，其第二换能振动装置220与储物间室110的内壁之间设有连接组件400。连接组件400包括第一连接板410和第二连接板420，第一连接板410的一端通过两个夹臂411对第二超声换能器221进行抱紧固定，另一端具有两个上下布置的卡勾412。第二连接板420固定至储物间室110的内壁，其上具有两个上下布置的卡口421。安装时将两个卡勾412对应勾挂在两个卡口421内，从而可以较为稳定地将第二换能振动装置220整体悬置在储物间室110内。
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。
