具体实施方式
下面结合附图和具体实施例来说明实施方式。
图1所示是搅拌器组件第一实施例示意图。搅拌器101可以是搅拌刀、搅拌棒、搅拌叶片、搅拌架中的一种搅拌器。搅拌器101和导热搅拌轴102机械连接，同时也具有热传导连接。热传导连接往往需要排除部件之间的间隙或者具有热阻效应的物质。一般有以下几种方式：1，使用导热硅脂或者液态金属填充两个部件之间的间隙；2，使用柔性的导热片夹在两个部件的接触面之间；3，更佳地，搅拌器和导热搅拌轴合体为一个部件，也可以将两个部件的接触面之间用焊接的焊料填满(焊接材料也是一种热的良导体)，达到无缝连接的效果。导热搅拌轴102带动搅拌器101转动，搅拌器101搅拌被加工的食材。导热搅拌轴102的另一端和半导体制冷片103的冷端具有热传导连接。半导体制冷片103的热端和散热器104具有热传导连接。
图2是半导体制冷片103的局部剖面示意图。半导体制冷片由N型半导体201、P型半导体202、导电导热体203、电绝缘导热体204构成。电绝缘导热体204的204a为冷端，204b为热端。制冷功率大小是由流通电流的大小以及N型半导体和P型半导体的数量决定。由图2可知，冷端204a和热端204b之间除了存在导电导热体203、N型半导体201以及P型半导体202，还存在很多空隙，这些空隙容易让热辐射和热对流造成损耗。本实施例下的一种可选实施方式是：冷端和热端之间的空隙用保温材料205填充，以减小损耗。
导热搅拌轴102包含有热的良导体构成的热传导部件。导热搅拌轴102可以是在现有技术搅拌轴的基础上增加热传导部件。导热搅拌轴102本身也可以由热的良导体构成的，这时导热搅拌轴102本身就是热传导部件。
半导体制冷片103的热端和散热器104必须具有可靠的热传导连接，否则容易因热量聚集、温度过高而损坏半导体制冷片。冷端用来给搅拌器101降温、带走热量，因此冷端和导热搅拌轴102也必须具有可靠的热传导连接。本实施例在搅拌食物时，搅拌器101、导热搅拌轴102、半导体制冷片103、散热器104作为一个整体一起转动，使半导体制冷片的热端和散热器、冷端和导热搅拌轴、导热搅拌轴和搅拌器都保持可靠的热传导连接，从而使制冷可靠并通过热传导作用到搅拌器101。
图1中半导体制冷片103为板状。相应地，导热搅拌轴102的下部成喇叭形扩大，并覆盖半导体制冷片103的整个冷端一侧。散热器104覆盖半导体制冷片103的整个热端一侧。导热搅拌轴、半导体制冷片、散热器的几何形状还可以有多种变化。
例如：导热搅拌轴下部没有喇叭形扩大，上下都为圆柱体。半导体制冷片的冷端、热端的平面相同并小于导热搅拌轴横截面。散热器和半导体制冷片热端接触面积也相应缩小，其下部的散热片成喇叭形放大，使散热面积足够。如果半导体制冷片还保持同样的制冷功率，因为冷端、热端两侧面积缩小，冷端、热端附近的热传导材料的导热性能要更高。
再如：一种异型的半导体制冷片，其冷端的面积小于热端的面积，使冷端可以和圆柱体的导热搅拌轴相连，热端可以和大面积的散热器(如104)相连。半导体制冷片内部的一些N型半导体和P型半导体会倾斜放置，其制造较为复杂。如果半导体制冷片还保持同样的制冷功率，因为冷 端面积缩小，冷端附近的热传导材料的导热性能要更高。
上述三种可选实施方式还可以取一些折中，形成多种组合。从成本角度，图1中示出的导热搅拌轴、半导体制冷片、散热器的几何形状是发明人当前认为最经济的方案。参考图1，可选的，导热搅拌轴102逐渐放大的部分和上面的圆柱体部分分开加工，然后再结合。本文为了节省篇幅，不管上述导热搅拌轴的几何形状作哪种变化、分成几个部分，都称之为：导热搅拌轴。
搅拌器101一般由金属构成，具有一定的热传导能力，从而制冷对搅拌器101的表面有一定的降温效果，可以消除一些摩擦热。不过现有技术的搅拌器并没有专门设计用于传导热量，它的热传导功率不一定很高。本实施方式主要应用于摩擦热产生功率不高的场合。图1所示的搅拌器101为两叶式搅拌器。一般搅拌器有2叶、4叶、6叶、8叶等多种。叶数越多，总的热传导功率越大。本实施方式采用现有技术的搅拌器，总的热传导功率也可以达到更高的水平。
本实施例搅拌器组件还具有：搅拌转矩接口105、转矩传递部件106、搅拌轴支承部件107、保温材料108。搅拌轴支承部件107具有密封和隔热的部件。保温材料108用来防止制冷效率的损耗。搅拌主机的扭转力矩通过搅拌转矩接口105施加给散热器104，然后施加到转矩传递部件106，再施加到导热搅拌轴102上，避免半导体制冷片103受力。本实施方式借用散热器104传递扭转力矩，是因为散热器104所处的位置并具有一定的机械强度。其实这并不是唯一的方式。也可以通过重新设计，让转矩传递部件将搅拌转矩接口105和导热搅拌轴102直接连接起来。
本第一实施例搅拌器组件，通过可靠地给搅拌器制冷，从摩擦热产生的部位带走一些热量。
图3所示是搅拌器组件第二实施例示意图。导热搅拌器301也包含有热的良导体构成的热传导部件。导热搅拌器301可以是在现有技术搅拌器的基础上增加热传导部件。导热搅拌器301本身也可以由热的良导体构成的，这时搅拌器301本身就是热传导部件。导热搅拌器301的热传导部件和导热搅拌轴102的热传导部件具有热传导连接。其他方面的实施方式参考搅拌器组件第一实施例。这样从半导体制冷片103的冷端到导热搅拌轴102、再到导热搅拌器301、一直到导热搅拌器301的产生摩擦热的表面，存在一个良好 的热传导通路。更便于从摩擦热的源头带走热量，从而更好地解决摩擦发热问题，便于食材的冷鲜加工。
在同等转速下，导热搅拌器301的叶数越多，总的摩擦生热的功率也就越高，需要制冷功率也就越高，导热搅拌轴就需要更大的导热横截面来提高热传导功率。上述热传导通路的导热能力需要根据各方面的参数精确地设计。
图4中的搅拌主机500、搅拌器组件100、搅拌杯体551共中心线，是三个部件装配关系的示意图。图5是上述三个部件装配完成示意图。图4中的搅拌杯体551上部未全部画出以适应版面大小，其全貌在图5中有展示。
搅拌器组件第三实施例参考图4、图5进行说明。因为搅拌器组件和搅拌主机相互配合工作，下文有些地方顺带描述了搅拌主机的实施方式。
搅拌器组件第三实施例在第一、第二实施例的基础上，进一步增加技术特征。本实施例下的第一种可选实施方式：包含磁感应线圈410。与磁感应线圈410配合的是搅拌主机500上的磁场发生模块510，所述磁场发生模块510可以由导电线圈构成，也可以由磁铁构成。磁感应线圈410通过电磁感应接收电能，给搅拌器组件100上的电子器件、电路供电。这样本实施方式的搅拌器组件100的外表面可以实现电绝缘，也容易实现防水功能。为了接收更多的电量，磁感应线圈410的数量可以大于等于1，同样磁场发生模块510的数量也可以大于等于1。
本实施例下的第二种可选实施方式，搅拌器组件100具有控制单元420和冷端温度传感器421、热端温度传感器422。控制单元420和冷端温度传感器421、热端温度传感器422都具有连接的电路(图中未示出)。控制单元420作为具有一定计算能力的数字电路，则可以产生多种更为灵活的控制方式。例如，从冷端的温度传感器421获取温度，如果冷端温度高于阈值，则加大制冷功率。如果冷端温度低于阈值，则减小制冷功率。再如，从热端温度传感器422获取温度，如果温度过高，减小制冷功率或者停止制冷。控制单元420还可以对热端温度过高，发出报警信号。控制单元420具有相应的执行电路(图中未示出)，用于开启、关闭半导体制冷片103的制冷，也用于调节半导体制冷片的运行功率。
更佳地，控制单元420包含有通信模块(图中未示出)，搅拌主机500也具有一个控制单元520并含有相应的通信模块(图中未示出)。控制单元420接收搅拌主机的扭转力矩和转速等信息，估算导热搅拌器301或搅拌器 与食物摩擦产生的热量，控制单元根据估算到的摩擦热产生功率，同时补偿热传导通路的损耗，最后输出合适的制冷功率。这样通过信息传递、处理和执行，保证食物加工过程中摩擦热聚集保持在一定的范围内。
更优地，控制单元420还可以控制搅拌器组件工作于边搅拌边制冷的状态。例如，对一定份量的室温果蔬的加工，当加工成果蔬泥的同时，把果蔬泥的温度也降到一个目标范围。控制单元420通过具备运算能力，还有可能再设计出多种更为智能的工作模式。
参考图5、图4，一种搅拌机的实施例。首先搅拌杯体551通过密封卡口和搅拌器组件耦合，形成搅拌杯。然后，搅拌杯体551再通过另一卡口和搅拌主机耦合，同时上述搅拌器组件的搅拌转矩接口105和搅拌主机的马达接口505也耦合。通过两个扭转力矩接口的耦合，将马达501的扭转力矩最终传递给搅拌器或者导热搅拌器。
更优地，在搅拌器组件的搅拌转矩接口105和搅拌主机的马达接口505耦合的同时，搅拌器组件的磁感应线圈410和搅拌主机的磁场发生模块510也到达相耦合的位置。搅拌器组件的磁感应线圈410随着搅拌器组件转动时，与磁场发生模块510作用产生感生电流，获得电能。
更优地，搅拌主机500还具有一个风扇模块502，图4、图5上风扇模块502有两个叶片。可选地，风扇模块具有n个叶片，n大于等于1。图5中风扇模块502和搅拌器组件的散热器104并不接触。实际上风扇模块502产生的风流用于散热器104的散热。风扇模块502的输出风流朝向所述搅拌器组件的散热器104的散热片。搅拌主机上具有风扇的进风口503。搅拌杯体551上具有风扇的出风口552。便于散热风流的流进和流出。为了有利于风冷，进风口503的数量为n个，n大于等于1。同样出风口552的数量也可以大于等于1。可选地，它们具有相应的导风板。可选地，它们具有风扇防护网。
更优地，搅拌主机的控制单元520和搅拌器组件的控制单元420通信，在风扇模块502的工作功率和散热器104的温度之间建立反馈调整机制，提高风冷效率，从而提高搅拌器组件的制冷效率。
搅拌主机还具有排水口506、风扇马达504。搅拌主机的外壳上还具有一些通风孔(图中未示出)，给马达散热。
参考图6，一种搅拌杯的实施例。当搅拌杯体651通过密封卡口连接了搅 拌器组件100后，搅拌杯600具有了容器功能。搅拌杯体651还具有一个密封盖653。这样形成的密封容器可以用来存储食物。搅拌杯体651外层具有保温材料654，可以对放入上述密封容器的食物进行保温。
搅拌器组件100还具有一个供电接口655，提供半导体制冷片以电能。所述供电接口655可以采用导线方式供电，也可以以无导线方式供电(通过磁感应线圈410接收电能)。在半导体制冷片制冷功率不大的情况下，散热器自然散热。更优地，搅拌杯体651具有一个散热风扇(图中未示出)对散热器风冷，提高制冷功率。该散热风扇在不用的情况下可以脱离搅拌杯体651。本搅拌杯600可以在脱离搅拌主机的状况下，给存储的食物降温。为了让存储食物位置不高于冷源的位置，一般把密封的搅拌杯600转90度左右放置。当需要搅拌所存储的食物时，和图4所示的搅拌主机500连接。本实施例搅拌杯600可以用于食物的保温存储、可以用于给食物降温、还可以用于食物的冷鲜搅拌，集多种功能于一体。
为了描述精简，不可避免地各个实施例之间有些相互参考，否则篇幅会过长、重复。每个实施例的实施方式应该在通读全文后，以所属技术领域人员的技术水平来理解。通常，上述实施例用于解释权利要求，本申请的保护范围并不局限于实施例，本申请的保护范围应该根据权利要求得到。
