具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的技术特征可以相互组合，具体实施方式中的详细描述应理解为本申请宗旨的解释说明，不应视为对本申请的不当限制。
在本申请实施例的描述中，需要说明的是，术语“上”、“下”等指示的方位或位置关系为基于附图1所示的方位或位置关系，其中，“顶底”为基于附图所示的上下方向，这些方位术语仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
本申请实施例提供了一种制冰设备，包括机体以及本申请任一实施例提供的制冰模块，制冰模块设置在机体内。
需要说明的是，制冰设备的具体类型在此不做限制，例如可以是制冰机，还可以是冰箱等。具体地，当制冰设备为冰箱时，制冰模块集成在冰箱内，也就是说，制冰设备至少具有常规的冰箱功能，此外，还具有制冰的功能。本申请实施例以制冰设备为集成有制冰模块的冰箱为例进行说明。
本申请实施例提供了一种制冰模块，请参阅图1至图8，该制冰模块包括外壳90、热交换单元10和刮冰组件20。
外壳90内具有制冰空间20a，制冰空间20a的底部具有出冰口20b，也就是说，制冰模块从底部出冰。
热交换单元10包括主换热器11，主换热器11设置在制冰空间20a内，主换热器11内填充有冷媒，冷媒可以与主换热器11表面的水进行热交换，以使水在主换热器11的表面生成冰。
可以理解的是，请参阅图1和图2，由于制冰空间20a的底部具有出冰口20b，因而，制冰空间20a内不会积蓄大量的水，该制冰模块生成冰所需的水是通过控制小流量的水流经主换热器11的表面，而小流量的水流通过 换热生成冰所需的换热量较小，由此，小流量的水流与主换热器11进行换热，能够在主换热器11的表面快速凝固并生成冰。
需要说明的是，主换热器11的具体类型在此不做限制，示例性地，主换热器11为蒸发器。
刮冰组件20与主换热器11间隔设置，用于将主换热器11表面生成的冰刮下。
制冰设备或者制冰模块还包括控制板以及其他制冷循环部件，其他制冷循环部件例如为压缩机、冷凝器、毛细管等，连接管道通过连通压缩机、冷凝器、热交换单元10等形成制冷系统，以使主换热器11表面的水能够冷凝成冰。
相关技术中，制冰模块的制冰空间的出冰口一般位于顶部，制冰空间内具有一定量的水，部分蒸发器位于在制冰空间的水里，水与蒸发器进行换热并在蒸发器的表面生成冰，通过刮冰器旋转将蒸发器表面生成的冰不断刮下，并将其不断送出蒸发器，从而使得蒸发器出口产生源源不断的碎冰。但是，由于制冰空间内水较多，水在蒸发器的表面生成冰所需的换热量较多，导致制冰速度较慢，不能即取即用。
而本申请实施例的制冰模块，外壳90通过设置底部具有出冰口20b的制冰空间20a，热交换单元10的主换热器11设置在制冰空间20a内，在制冰的时候，通过向制冰空间20a内供水，水流在重力作用下顺着主换热器11往下流动并在主换热器11的表面生成冰，通过刮冰组件20将主换热器11表面生成的冰刮下，也就是说，通过在制冰空间20a的底部设置出冰口20b，需要制冰的时候，通过向制冰空间20a供水，水流顺着主换热器11往出冰口20b流动时能够与主换热器11进行换热并在主换热器11的表面快速凝固，通过刮冰组件20将主换热器11表面生成的冰刮下并从底部的出冰口20b出来，以实现即取即用的快速制冰，由此，提高了制冰模块的 制冰速度。
一实施例中，请参阅图1，热交换单元10包括辅助换热器12，制冰模块包括与制冰空间20a连通的供水单元40，供水单元40的水流与辅助换热器12换热后进入制冰空间20a，也就是说，通过设置辅助换热器12，以使供水单元40的水流与辅助换热器12换热，即通过辅助换热器12对水流进行预冷后再进入制冰空间20a，经辅助换热器12预冷后的水流顺着主换热器11往出冰口20b流动时能够与主换热器11进行换热并在主换热器11的表面快速凝固。
可以理解的是，通过辅助换热器12对进入制冰空间20a的水流进行预冷，经过预冷后的水流生成冰所需的换热量更少，即更容易在主换热器11的表面凝固生成冰，进而，进一步地提高了制冰速度。
需要说明的是，辅助换热器12的具体设置方式在此不做限制，只要能够实现对进入制冰空间20a的水流进行预冷即可，示例性地，一实施例中，请参阅图1，主换热器11的主冷媒出口11c与辅助换热器12的辅助冷媒入口12a连通，也就是说，辅助换热器12与主换热器11串联在冷媒循环回路中，主换热器11内的冷媒经过与流经主换热器11表面的水流换热后从主冷媒出口11c流出，经辅助换热器12的辅助冷媒入口12a进入辅助换热器12内，然后与流经辅助换热器12的水流进行换热以对流经辅助换热器12的水流进行预冷，然后经辅助换热器12的辅助冷媒出口12b流出，接着流经压缩机、冷凝器等循环流入主换热器11。
可以理解的是，通过设置主换热器11的主冷媒出口11c与辅助换热器12的辅助冷媒入口12a连通，一方面可以节省能源，对冷媒的冷量进行充分的利用，即先利用冷媒的冷量与制冰空间20a内的水流进行换热，以使水流在主换热器11的表面凝固生成冰，冷媒在流经辅助换热器12时，还能够利用冷媒剩余的冷量以对进入制冰空间20a内的水流进行预冷；另一 方面，能够有效避免水流在辅助换热器12处凝固生成冰，可以理解的是，较低温度的冷媒在主换热器11内与水流换热后温度升高，再进入辅助换热器12时，不会因为温度过低而导致水流在辅助换热器12处凝固生成冰；又一方面，可以使得热交换单元10的结构简单，通过一条冷媒循环回路即可实现水流在主换热器11的表面与冷媒换热凝固生成冰，以及水流在辅助换热器12处与冷媒换热进行预冷。
一具体实施例中，主换热器11的主冷媒入口11b处的冷媒温度约为-5℃，主换热器11的主冷媒出口11c处的冷媒温度约为-2℃，辅助换热器12的辅助冷媒入口12a处的冷媒温度约为0℃。
另一些实施例中，辅助换热器12与主换热器11并联在冷媒循环回路中，也就是说，冷媒回路中的冷媒一部分进入主换热器11内，另一部分进入辅助换热器12内。
一实施例中，请参阅图1，制冰模块包括储冰单元50，储冰单元50位于出冰口20b的下方，用于接收来自出冰口20b的冰块。
储冰单元50包括具有蓄水槽51a的蓄水盒51，蓄水盒51位于出冰口20b的下方，蓄水盒51的蓄水槽51a用于接收流经主换热器11未结冰的水流，或者蓄水盒51上的冰块熔化的水流流入蓄水槽51a，进而能够避免冰箱内积水造成发霉等问题。

一具体实施例中，冰箱具有制冰模式，杀菌模式等，以下对几种模式的控制进行描述。
当制冰模式开启：第二开关阀43开启，第一开关阀63关闭，PTC加热器71关闭，水泵62关闭，刮冰组件20和推杆100开启。此时，水箱41内的水流经供水管路42进入至制冰空间20a，并在主换热器11的表面进行换热凝固生成冰，刮冰组件20开启将主换热器11表面凝固生成的冰刮下，推杆100做往复式运动不停地将滤网表面的冰块推出，以实现连续不断地制冰。
当制冰模式停止：第二开关阀43关闭，第一开关阀63开启，PTC加热器71关闭，水泵62开启，刮冰组件20和推杆100关闭。此时，制冰结束，蓄水槽51a内蓄积了一部分水，通过水泵62将蓄水槽51a内的积水抽回至水箱41。

请参阅图1至图3，刮冰组件20设置在外壳90内，刮冰组件20包括第一刮冰器21和第二刮冰器22，第一刮冰器21位于主换热器11的一侧，第二刮冰器22位于主换热器11背离第一刮冰器21的一侧，也就是说，第一刮冰器21和第二刮冰器22分别位于主换热器11的相对两侧。
本申请实施例的制冰模块，设置了包括第一刮冰器21和第二刮冰器22的刮冰组件20，第一刮冰器21位于主换热器11的一侧，第二刮冰器22位于主换热器11背离第一刮冰器21的一侧。在制冰的时候，可以利用第一刮冰器21将主换热器11一侧结的冰刮下，利用第二刮冰器22将主换热器11背离第一刮冰器21一侧结的冰刮下，也就是说，通过利用主换热器11相对两侧的换热面积进行换热并生成冰，并通过设置包括第一刮冰器21和第二刮冰器22的刮冰组件20进行刮冰，从而提高了主换热器11的换热量，进而提高了制冰速度。
需要说明的是，主换热器11的具体结构不做限制，示例性地，请参阅图2、图4和图6，主换热器11包括换热柱筒111，换热柱筒111内形成冷媒容纳腔11a，也就是说，换热柱筒111的内壁与外壁之间形成冷媒容纳腔11a，换热柱筒111的冷媒容纳腔11a内用于填充冷媒，冷媒与换热柱筒111的内壁以及外壁周侧的水均可以进行热交换，以使水在换热柱筒111的内壁以及外壁的周侧结冰，可以理解的是，一方面，采用换热柱筒111的结构形式，提高了主换热器11的换热面积，另一方面，冷媒与换热柱筒111的内壁以及外壁表面的水均可以进行热交换，进一步地提高了主换热器11的换热面积，由此，能够提高主换热器11的换热量以及主换热器11表面生成冰的速度。
需要说明的是，换热柱筒111的具体结构在此不做限制，换热柱筒111包括但不限于为圆形柱筒、方形柱筒、锥台柱筒等。
相关技术中，制冰机采用螺杆外壁面缠绕铜管的方式作为热交换单元，而本申请实施例的热交换单元设置为换热柱筒，这样相比于缠绕铜管的方式增加了换热面积，进而提高了制冰速度。
请参阅图1至图3，第一刮冰器21位于换热柱筒111的内侧，第二刮冰器22位于换热柱筒111的外侧。也就是说，通过将第一刮冰器21设置在换热柱筒111的内侧，可以将换热柱筒111的内侧结的冰刮下来，将第二刮冰器22设置在换热柱筒111的外侧，可以将换热柱筒111的外侧结的冰刮下来，进而提高了制冰速度。
一些实施方式中，主换热器11还可以是局部为环形的，第一刮冰器21和第二刮冰器22分别位于主换热器11的相对两侧。
另一些实施方式中，主换热器11还可以是板状的，第一刮冰器21和第二刮冰器22分别位于主换热器11的相对两侧。
一实施例中，请参阅图2、图3以及图8，第二刮冰器22包括环形柱 筒221以及呈螺旋状环绕在环形柱筒221内壁上的第二螺片222，也就是说，环形柱筒221套设在换热柱筒111的外侧，一方面，能够充分利用主换热器11的换热柱筒111的换热面积，从而提高制冰速度，另一方面，通过在环形柱筒221内壁上设置呈螺旋状环绕的第二螺片222，提高了第二刮冰器22对换热柱筒111的外壁的刮冰效率，从而进一步地提高了制冰效率。
请参阅图1至图3，第一刮冰器21位于环形柱筒221的内侧并与第二刮冰器22之间限定出制冰空间20a，也就是说，可以通过控制水流流经制冰空间20a的换热柱筒111，以使换热柱筒111充分与水接触，另外，环形柱筒221、第一刮冰器21以及换热柱筒111同轴设置，能够方便第一刮冰器21和第二刮冰器22分别对换热柱筒111的外壁以及内壁表面进行刮冰，且不会发生相对干涉，另外，还提高了制冰模块的结构稳定性和紧凑性。
一实施例中，请参阅图1至图3、图7，第一刮冰器21包括螺杆211以及呈螺旋状环绕在螺杆211上的第一螺片212。第一刮冰器21位于换热柱筒111的的内侧，第一螺片212呈螺旋状环绕在螺杆211上，用于对换热柱筒111内侧结的冰进行刮冰，进而提高了制冰速度。
一实施例中，请参阅图2和图6，换热柱筒111自上而下逐渐向内收缩，也就是说，换热柱筒111的外形尺寸随着靠近出冰口20b而逐渐减小，即换热柱筒111的外壁以及内壁与转动中心之间的距离自上而下逐渐减小，如此，换热柱筒111在高度方向的尺寸一定的情况下，增大了水流沿换热柱筒111的表面流动的距离，从而提高了水流与主换热器11的换热量，进而提高了水流在主换热器11的表面生成冰概率，即提高了制冰效率。另外，由于换热柱筒111自上而下逐渐向内收缩，即换热柱筒111倾斜设置，可以使得水流沿着换热柱筒111的表面往下流动，从而避免部分水流直接从主换热器11与刮冰组件20之间的间隙掉出制冰空间20a。
可以理解的是，由于换热柱筒111自上而下逐渐向内收缩，第一刮冰 器21以及第二刮冰器22也做适应性的倾斜，使得第一刮冰器21以及第二刮冰器22与换热柱筒111的倾斜角度适配，进而能够顺利高效的进行刮冰。
需要说明的是，换热柱筒111的倾斜角度在此不做限制，示例性地，换热柱筒111自上而下的向内收缩角度为3°～20°，该角度范围内的水流换热效率以及结冰效率高，且能够使得制冰模块的结构紧凑。
另一些实施例中，换热柱筒111自下而上逐渐向内收缩，也就是说，换热柱筒111的外形尺寸随着靠近出冰口20b而逐渐增大，即换热柱筒111的外壁以及内壁与转动中心之间的距离自下而上逐渐减小，如此，换热柱筒111在高度方向的尺寸一定的情况下，增大了水流沿换热柱筒111的表面流动的距离，从而提高了水流与主换热器11的换热量，进而提高了水流在主换热器11的表面生成冰概率，即提高了制冰效率。另外，由于换热柱筒111自下而上逐渐向内收缩，即换热柱筒111倾斜设置，可以使得水流沿着换热柱筒111的表面往下流动，从而避免部分水流直接从主换热器11与刮冰组件20之间的间隙掉出制冰空间20a。
又一些实施例中，换热柱筒111为圆柱状，也就是说，即换热柱筒111的外壁以及内壁与转动中心之间的距离不变。
需要说明的是，刮冰组件20与主换热器11之间的配合方式有多种，且根据刮冰组件20与主换热器11之间的不同配合方式，刮冰组件20对主换热器11表面结的冰进行刮冰的方式也不同，本申请在此不做限制，只要刮冰组件20与主换热器11之间能够发生相对位移以进行刮冰即可，例如，刮冰组件20与主换热器11可以发生相对平动，相对转动等。
示例性地，请参阅图2，制冰模块包括驱动单元30，驱动单元30能够驱动刮冰组件20相对换热柱筒111转动。也就是说，换热柱筒111固定不动，驱动单元30与第一刮冰器21以及第二刮冰器22驱动连接，驱动单元30通过驱动环形柱筒221环绕换热柱筒111转动，以使环形柱筒221内壁 上的第二螺片222不停地将换热柱筒111外壁上生成的并刮下，驱动单元30通过驱动螺杆211转动，以使呈螺旋状环绕在螺杆211上的第一螺片212不停地将换热柱筒111内壁上生成的冰刮下，由于环形柱筒221、螺杆211以及换热柱筒111同轴设置，刮冰组件20转动过程中不会与换热柱筒111干涉，另外，该结构稳定且制冰速度快。
一些实施方式中，驱动单元30能够驱动换热柱筒111相对刮冰组件20转动。也就是说，第一刮冰器21以及第二刮冰器22固定不动，驱动单元30与换热柱筒111驱动连接，驱动单元30通过驱动换热柱筒111转动，以使换热柱筒111外壁上生成的冰被环形柱筒221内壁上的第二螺片222不停地刮下，以使热柱筒内壁上生成的冰被螺杆211上的第一螺片212不停地刮下。
另一些实施方式中，驱动单元30能够驱动刮冰组件20相对换热柱筒111沿轴向移动。也就是说，换热柱筒111固定不动，驱动单元30与第一刮冰器21以及第二刮冰器22驱动连接，驱动单元30通过驱动环形柱筒221沿轴向移动，以使环形柱筒221内壁上的第二螺片222不停地将换热柱筒111外壁上生成的并刮下，驱动单元30通过驱动螺杆211沿轴向移动，以使呈螺旋状环绕在螺杆211上的第一螺片212不停地将换热柱筒111内壁上生成的冰刮下，由于环形柱筒221、螺杆211以及换热柱筒111同轴设置，刮冰组件20转动过程中不会与换热柱筒111干涉，另外，该结构稳定且制冰速度快。
再一些实施方式中，驱动单元30能够驱动换热柱筒111相对刮冰组件20沿轴向移动。也就是说，第一刮冰器21以及第二刮冰器22固定不动，驱动单元30与换热柱筒111驱动连接，驱动单元30通过驱动换热柱筒111沿轴向移动，以使换热柱筒111外壁上生成的冰被环形柱筒221内壁上的第二螺片222不停地刮下，以使热柱筒内壁上生成的冰被螺杆211上的第 一螺片212不停地刮下。
需要说明的是，驱动单元30驱动刮冰组件20相对换热柱筒111转动的具体方式在此不做限制，例如可以分别单独驱动第一刮冰器21和第二刮冰器22，也可以同时驱动第一刮冰器21和第二刮冰器22，示例性地，请参阅图2，刮冰组件20包括与第一刮冰器21以及第二刮冰器22均连接的转盘23，驱动单元30与转盘23驱动连接，也就是说，驱动单元30通过驱动转盘23转动，进而带动第一刮冰器21和第二刮冰器22转动，提高了驱动单元30与刮冰组件20的结构稳定性。
其中，转盘23的具体结构在此不做限制，例如转盘23可以是与第二刮冰器22一体成型，即可以是构成环形柱筒221的一部分，然后与第一刮冰器21连接，驱动单元30通过驱动转盘23转动，进而带动第一刮冰器21和第二刮冰器22转动；转盘23也可以是与第一刮冰器21一体成型，然后与第二刮冰器22连接，驱动单元30通过驱动转盘23转动，进而带动第一刮冰器21和第二刮冰器22转动，示例性地，请参阅图2，转盘23是与第一刮冰器21以及第二刮冰器22均独立的单独零件，转盘23与第一刮冰器21以及第二刮冰器22均连接。
需要说明的是，给制冰空间20a供水的具体方式在此不做限制，例如可以直接向制冰空间20a供水，示例性地，请参阅图2和图3，转盘23形成有与制冰空间20a连通的过水通道23a，制冰模块包括与过水通道23a连通的供水单元40，也就是说，通过在转盘23上设置与制冰空间20a连通的过水通道23a，供水单元40通过过水通道23a向制冰空间20a供水，提高了制冰模块的结构紧凑性以及可靠性，另外，还能够避免供水单元40影响刮冰组件20的转动。
一实施例中，第一刮冰器21包括设置在螺杆211靠近转盘23一端的安装座(图未示)，安装座盖设在过水通道23a上，也就是说，第一刮冰器 21通过安装座与转盘23连接，以使转盘23带动第一刮冰器21一起转动。
安装座上设置有连通制冰空间20a和过水通道23a的第一过水孔，也就是说，供水单元40流入过水通道23a的水经第一过水孔进入制冰空间20a，安装座的设置，在实现第一刮冰器21安装在转盘23的同时，还能够实现过水通道23a的水经第一过水孔进入制冰空间20a。
可以理解的是，为了便于第一刮冰器21安装在转盘23的同时，还能够实现过水通道23a的水进入制冰空间20a，过水通道23a随着逐渐靠近第一刮冰器21而呈外扩状，如此设置，一方面，便于水流的流动，另一方面，能够使得安装座第一过水孔在连通过水通道23a的同时，避开螺杆211。
一实施例中，请参阅图2，制冰模块包括具有冰成型孔80a的冰成型板80，冰成型板80盖设在制冰空间20a的出冰口20b处，驱动单元30驱动刮冰组件20转动时，推动制冰空间20a内冷凝产生的冰经由冰成型板80成型并挤出。
请参阅图1、图2、图4和图6，主换热器11包括冷媒进管112和冷媒出管113，冷媒经冷媒出管113进入主换热器11，并经冷媒出管113流出主换热器11，从而实现冷媒的循环流动。
冷媒进管112的出口位于冷媒容纳腔11a的底部，冷媒出管113的进口位于冷媒容纳腔11a的顶部，如此，可以使得主换热器11的内部充满冷媒，另外，还可以使得其符合热分层效应，即较低温度的冷媒位于底部，较高温度位于顶部，提高了制冰速度。
为了防止主换热器11表面结冰过厚而导致无法从表面刮下，从而减小热导率，需要控制第一刮冰器21与主换热器11之间的距离，示例性地，第一刮冰器21与主换热器11的距离为0.2mm～1mm，由此，在防止主换热器11表面结冰过厚而导致无法从表面刮下的同时，还能够防止第一刮冰器21与主换热器11之间发生干涉。
一实施例中，第二刮冰器22与主换热器11的距离为0.2mm～1mm，由此，在防止主换热器11表面结冰过厚而导致无法从表面刮下的同时，还能够防止第二刮冰器22与主换热器11之间发生干涉。
可以理解的是，第一刮冰器21以及第二刮冰器22与主换热器11的距离可以一致，也可以不同，可以根据实际情况决定。
一实施例中，请参阅图2和图5，制冰模块包括衬套110以及减阻钢珠120，衬套110设置在刮冰组件20与外壳90之间，减阻钢珠120设置在衬套110内且与刮冰组件20抵接，也就是说，通过在外壳90和刮冰组件20之间的衬套110中设置减阻钢珠120，从而将刮冰组件20与衬套110之间存在的接触滑动摩擦转化为滚动摩擦，从而减小转动所需扭矩。
一实施例中，请参阅图2和图5，制冰模块包括减阻钢珠120以及设置在出冰口20b处的冰成形板，减阻钢珠120设置在冰成形板上且与刮冰组件20抵接，也就是说，通过在刮冰组件20和冰成形板之间设置减阻钢珠120，从而将刮冰组件20与冰成形板存在的接触滑动摩擦转化为滚动摩擦，从而减小转动所需扭矩。
