相关申请的交叉引用
本申请基于申请号为201810541350.7，申请日为2018年05月30日的中国专利申请提出，并要求上述中国专利申请的优先权，上述中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及流体泵，具体地涉及一种集成加热泵及洗碗机。
背景技术
集成加热泵区别于传统的流体泵，其既能够对泵体内的流体进行加热，同时又能够将加热后的流体泵送至指定位置。
加热功率是集成加热泵的一个重要的参数，通常会根据实际需要加大集成加热泵的加热功率，具体也就是增大加热管的功率，通常通过增加管径和管长度而实现加热管功率的增加，这样势必会导致集成加热泵的某一方向尺寸较大，从而会影响产品的性能。以洗碗机为例，一般地，洗碗机包括集成加热泵以及位于该集成加热泵上方的容纳腔，该容纳腔也是洗碗机的工作空间，用于放置待清洗的碗具。当洗碗机整体高度一定的情况下，如果为了增加加热管的加热功率而导致了集成加热泵整体高度的增加，这样势必会减小容纳腔的尺寸。
因此，需要提供一种既能够增大加热功率，同时又不会影响洗碗机容纳腔的尺寸。
申请内容
本申请的目的是为了克服现有技术存在的加热功率的增加会导致洗碗机容纳腔的尺寸的问题，提供一种集成加热泵，该集成加热泵加热功率的增大，不会增大集成加热泵沿指定方向的尺寸，进而不会影响洗碗机容纳腔的尺寸。
为了实现上述目的，本申请一方面提供一种集成加热泵，所述集成加热泵包括：泵壳，所述泵壳具有进水口和出水口；加热组件，所述加热组件包括与所述泵壳固定的加热本体以及固定在所述加热本体上的发热体，所述发热体布置在所述加热本体的第一位置，所述第一位置设置使得所述发热体安装后所述集成加热泵沿指定方向的尺寸等于或小于所述发 热体安装前所述集成加热泵沿所述指定方向的尺寸；导热隔离套，所述导热隔离套具有与所述进水口和所述出水口均连通的流体通道，所述导热隔离套与所述加热组件导热连接并用于将所述流体通道中的液体与所述发热体隔离开。
可选地，所述加热本体为中空环状结构，所述导热隔离套位于所述加热本体中，所述加热本体在所述指定方向的尺寸小于该加热本体在其他方向的尺寸。
可选地，所述加热本体包括两个相对设置的弧形壁和两个相对设置的平坦壁，两个所述弧形壁之间的距离大于两个所述平坦壁之间的距离，两个所述平坦壁之间的垂直连线所在的方向为所述指定方向，所述发热体与所述弧形壁固定。
可选地，所述发热体为1个并设置在其中一个所述弧形壁上；和/或所述发热体包括多段所述弧形段与多段所述竖直段，多段所述弧形段形成多层结构，多段所述竖直段平行设置并朝向外部电源延伸。
可选地，所述导热隔离套为圆筒状，所述发热体为发热管，所述发热管包括弧形段与竖直段，所述弧形段的弧度与所述弧形壁的弧度相匹配并且与圆筒状的所述导热隔离套的对应位置处的弧度相匹配。
可选地，所述发热体为两个并对称的设置在相对的两个所述弧形壁上；和/或每个所述发热体包括多段所述弧形段与多段所述竖直段，多段所述弧形段形成多层结构，多段所述竖直段平行设置并朝向外部电源延伸。
可选地，两个所述平坦壁之间的距离为所述集成加热泵在所述指定方向上的最大尺寸；和/或所述加热本体为铸铝件，所述发热体的一部分通过铸铝成型工艺内嵌在所述加热本体中。
可选地，所述集成加热泵包括电机以及与所述电机连接的叶轮，所述进水口延伸至所述叶轮的入口处。
可选地，所述泵壳包括上泵壳和下泵壳，所述上泵壳、加热组件以及下泵壳依次布置并通过紧固件固定，所述叶轮位于所述上泵壳和下泵壳之间且所述下泵壳的包围所述叶轮的表面为弧形面。
可选地，所述上泵壳与所述导热隔离套、所述导热隔离套与所述下泵壳均通过密封圈密封。
本申请第二方面提供一种洗碗机，所述洗碗机包括用于容纳待洗碗具的容纳腔和所述的集成加热泵，所述容纳腔位于所述集成加热泵的上方，所述指定方向为所述洗碗机的高度方向。
在本申请中，由于发热体的安装并不会导致集成加热泵在指定方向(例如洗碗机的高度方向)上的尺寸的增加，这样为了增加发热体的发热功率就不会使得集成加热泵的沿洗碗机的高度方向的尺寸增加，这样在洗碗机总尺寸一定的情况下，发热体的安装就不会导致集成加热泵上方的容纳腔的空间的减小，从而不会影响洗碗机的工作空间。另外，在本申请中，由于所述导热隔离套用于将流体通道中的液体与发热体隔离开，因此发热体是设置在导热隔离套外部，即发热体是位于流体通道外部，从而使得发热体不会由于其中进水而发生损坏，而且可以一定程度上避免安全隐患。

具体实施方式
以下结合附图对本申请的具体实施方式进行详细说明。应当理解的是，此处所描述的 具体实施方式仅用于说明和解释本申请，并不用于限制本申请。
在本申请中，在未作相反说明的情况下，使用的方位词如“上、下、左、右、顶、底”通常是针对附图所示的方向而言的或者是针对竖直、垂直或重力方向上而言的各部件相互位置关系描述用词。另外，“内、外”是指相对于各部件本身的轮廓的内、外。另外，本申请中所指的“多个”指的是两个以上并且包括两个。
下面将参考附图并结合实施方式来详细说明本申请。
根据本申请的一个方面，结合图1和图2所示，本申请的具体实施方式提供的集成加热泵包括泵壳10、加热组件20以及导热隔离套30。其中，所述泵壳10具有进水口11和出水口12。所述加热组件20包括与泵壳10固定的加热本体21以及固定在加热本体21上的发热体22，所述发热体22布置在加热本体21的第一位置，所述第一位置设置为发热体22的安装不会增加集成加热泵沿指定方向的尺寸，例如，在本申请中，将集成加热泵应用至洗碗机中，使用时，为了不影响洗碗机的用于容纳待洗碗具的容纳腔的空间，需要控制洗碗机沿高度方向的尺寸，也就是下文中加热本体21的两个平坦壁21b之间的距离的大小，因此这种情况下指定方向是指洗碗机的高度方向，也是加热本体21的两个平坦壁21b之间的垂直连线所在的方向。当然，根据实际情况，这里的指定方向也可以是其他方向。
进一步地，结合图5所示，所述导热隔离套30具有与进水口11和出水口12均连通的流体通道31，所述导热隔离套30与所述加热组件20导热连接并用于将流体通道31中的液体与发热体22隔离开。其中这里的导热连接是指，热量能够从加热组件20的加热本体21快速传导至导热隔离套30，进而加热流体通道31中的液体。
根据本申请的另一个方面，本申请的具体实施方式提供的洗碗机包括用于容纳待洗碗具的容纳腔和所述的集成加热泵，所述容纳腔位于集成加热泵的上方，所述指定方向为洗碗机的高度方向。
以洗碗机为例，使用时，冷水从进水口11中进入集成加热泵中，并进入流体通道31中通过加热组件20加热，加热后的水通过出水口12排出，从而用于清洗碗具。在本申请中，由于发热体的安装并不会导致集成加热泵在指定方向(例如洗碗机的高度方向)上的尺寸的增加，这样为了增加发热体的发热功率就不会使得集成加热泵的沿洗碗机的高度方向的尺寸增加，这样在洗碗机总尺寸一定的情况下，发热体22的安装就不会导致集成加热泵上方的容纳腔的空间的减小，从而不会影响洗碗机的工作空间。另外，在本申请中，由于所述导热隔离套30用于将流体通道31中的液体与发热体22隔离开，因此发热体22是设置在导热隔离套30外部，即发热体是位于流体通道31外部，从而使得发热体22不会由 于其中进水而发生损坏，而且可以一定程度上避免安全隐患。
其中，结合图4和图5所示，所述加热本体21为中空环状结构，所述导热隔离套30位于加热本体21中，所述加热本体21在指定方向的尺寸小于该加热本体21在其他方向的尺寸。这样，在使用时，可以进一步减小集成加热泵沿指定方向的尺寸。另外，所述加热本体21可以为铸铝件，所述发热体22的一部分通过铸铝成型工艺内嵌在所述加热本体21中。这种情况下，加热本体21可以与导热隔离套30焊接，这样，加热本体21通过发热体22发热，热量经过加热本体21传导到导热隔离套30内壁加热液体。
具体的，所述加热本体21可以包括两个相对设置的弧形壁21a和两个相对设置的平坦壁21b，两个弧形壁21a之间的距离大于两个平坦壁21b之间的距离，结构简单、容易实现。其中，两个平坦壁21b之间的垂直连线所在的方向为指定方向，所述发热体22与弧形壁21a固定。当然，根据实际需要，如图6和图7所示，所述发热体22也可以为1个并设置在其中一个弧形壁21a上。
进一步地，所述导热隔离套30为圆筒状，所述发热体22为发热管，发热管可以通过电阻丝穿过金属管，并在其空隙内填充导热填料(例如MgO)而形成。所述发热管包括弧形段与竖直段，其中，为了便于安装和加工，同时也为了能够使加热面积更大，可选地，所述弧形段的弧度与弧形壁21a的弧度相匹配并且与圆筒状的导热隔离套30的对应位置处的弧度相匹配。
更进一步地，为了提高加热组件20的加热功率，可以增加发热管的管径或长度，其中发热管长度的增加可以通过增加发热管的数量实现(当然还可以通过增加每一根发热管的长度的方式实现)，例如，如图4和图5所示，本实施方式中所述发热体22为两个并对称的设置在相对的两个弧形壁21a上；和/或每个发热体22包括多段所述弧形段与多段所述竖直段，多段所述弧形段形成多层结构，多段所述竖直段平行设置并朝向外部电源延伸。其中，可以在发热管的一部分竖直段上设置接电端子，从而能够使得发热管与外部电源连接。
另外，所述上泵壳10a处延伸有出水管，所述出水管的端部形成上述出水口，其中所述出水管设置在所述上泵壳10的一侧。其中，为了尽可能的使得洗碗机的集成加热泵上方的容纳腔的空间更大，可选地，如图3所示，所述加热本体21的两个平坦壁21b之间的距离s1为集成加热泵在指定方向上的最大尺寸。这样也就说明了出水管的外边缘距离加热本体21端面的最大距离s2不大于两个平坦壁21b之间的距离s1。
其中，继续参考图1和图2，可以理解的是，所述集成加热泵还包括与加热组件20 固定的电机(例如可以通过螺钉将加热组件与电机40固定)40以及与电机40连接的叶轮50，具体的，叶轮50与电机40的转轴连接，以随电机转轴一起旋转。进一步地，所述进水口11延伸至叶轮50的入口处，这样可以防止液体从叶轮50流出之后再通过进水口回流，从而造成压力损失。
更进一步地，为了便于安装进而拆卸，所述泵壳10设置为分体式，具体的，所述泵壳10包括上泵壳10a和下泵壳10b，其中，上泵壳10a和下泵壳10b可以均为塑料件，重量轻、体积小，有一定的隔热效果，而且不容易腐蚀，使用和制造陈本较低。其中，所述上泵壳10a、加热组件20以及下泵壳10b依次布置并通过紧固件60固定(例如，可以在加热组件20上设置螺柱61，并在上泵壳和下泵壳的相应位置设置安装孔，这样可以通过螺栓或者螺钉而将三者固定在一起)，其中，上泵壳10a、加热组件20(具体是流体通道31)和下泵壳10b组成集成加热泵的泵腔。进一步地，所述叶轮50位于泵壳内并位于上泵壳10a和下泵壳10b之间且所述下泵壳10b的包围所述叶轮50的表面为弧形面，这样可以使叶轮50喷出的流向出水口方向的水进行旋转运动，弧形面可以对从叶轮50流出的水起到导向的作用。
另外，为了防止漏水，出现安全问题，所述上泵壳10a与导热隔离套30、导热隔离套30与下泵壳10b均通过密封圈70密封。
本申请提供的集成加热泵，一方面将加热和泵送装置集合在一起，更重要的是兼顾加热效率和集成加热泵沿指定方向的尺寸，而且，结构简单、容易实现。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于此。在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本申请所公开的内容，均属于本申请的保护范围。
