加热泵常用于需要对流体进行加热和泵送，现有的加热泵一般是在泵的壳体上预留供加热组件安装的安装位置，在壳体制造好以后，再将加热组件安装到壳体上，二者独立制造后再组装，安装工序相对较多；为了安装加热组件，必然需要有操作空间，在设计壳体时需要考虑该因素，不利于壳体小型化设计；且壳体和加热组件各自独立占据空间，整体占据的空间较大。
如图1至图5所示，其为加热泵的第一种实施例的示意图，加热泵包括壳体100、加热件200、叶轮组件300。壳体100内部设置有腔体110，腔体110具有进水口120及出水口130，进水口120及出水口130皆与腔体110连通，以便流体流入和流出；加热件200与壳体100一体压铸成型，以形成一体式结构，压铸是利用高压将金属液高速压入一精密金属模具型腔内，金属液在压力作用下冷却凝固而形成铸件；叶轮组件300可转动地安装于壳体100，且叶轮组件300部分位于腔体110内，用于驱动腔体110内的流体从进水口120流动至出水口130，具体而言，叶轮组件300的输出部分位于腔体110内。本领域技术人员可以理解的是，其中加热件200还可以采用其它方式与壳体100一体成型，例如，加热件200可以采用挤压铸造的方式与壳体100一体成型；挤压铸造是使液态或半固态金属在高压下凝固、流动成形，直接获得制件或毛坯的方法，它具有液态金属利用率高、工序简化和质量稳定等优点。
上述的加热泵通过将加热件200与壳体100一体成型，利用壳体100现有空间容纳加热体，可以减少整体空间占比，提高空间利用率，利于产品小型化设计；同时减少将加热件200装配到壳体100上的装配工序，提高装配效率。
需要说明的是，加热件200可以部分被壳体100的侧壁包裹，或者全部被壳体100包裹。
具体而言，如图2所示，加热件200包括用于发热的工作部210和用于接电的接线部220，工作部210全部被包裹于壳体100的侧壁内，接线部220至少部分位于壳体100外，以便和电源线对接。在本实施例中，工作部210完全位于壳体100的侧壁内，工作部210发出的热量全部传递给壳体100，再由壳体100对腔体110内的流体进行加热，可以对腔体110内的流体进行均匀加热；工作部210也不需要直接接触待加热的流体，可以有效保障工作部210的使用寿命。
当然，本领域技术人员可以理解的是，工作部210并不局限于上述的实施例，其还可以采用部分被壳体100的侧壁包裹的方式实施，例如，在某些需要对流体进行快速加热的使用场景下，工作部210具有至少一个面外露于壳体100的侧壁，其余部分被壳体100的侧壁包裹，此时工作部210有一部分可以直接与待加热的流体接触，直接进行热交换，实现快速加热流体的目的。本实施例启动后，加热件200同步对液体和上泵壳140进行加热；加热件200全部被上泵壳140的侧壁包裹的实施例启动后，加热件200先对上泵壳140进行加热，然后通过上泵壳140对液体进行加热，加热件200发出的所有热量需要经过上泵壳140后才能传递给液体；由上可见，本实施例相对加热件200全部被上泵壳140的侧壁包裹的实施例可以减少从开始工作后到达设定温度的响应时间。
举例来讲，加热件200采用现有成熟技术中的电发热管，压铸时，先将电发热管放置于模具，然后往模具中注入金属，金属与电发热管在模具中一体压铸成型。
如图1和图2所示，在本公开的一些实施例中，壳体100包括上泵壳140及下泵壳150，上泵壳140及下泵壳150可拆卸地连接，藉此，上泵壳140和下泵壳150分别独立制造，然后再组装在一起，具体而言，上泵壳140和下泵壳150可以通过螺纹结构或者螺栓或者螺钉连接在一起；腔体110设置于上泵壳140，进水口120和出水口130均设置在上泵壳140，叶轮组件300安装于下泵壳150，叶轮组件300部分相对下泵壳150向上凸出设置，且位于腔体110内，加热件200与上泵壳140一体压铸成型，以形成一体式结构。
壳体100分成两部分，可以降低加工难度，提高加工效率，降低加工成本，同时也使得上泵壳140和下泵壳150可以根据实际需求选择合适的材料制作，利于降低整体成本。例如，由于上泵壳140需要承担高温以及起到快速传递热量的作用，故而上泵壳140可以采用金属材质制作，利于将工作部210上的热量快速传递给流体，同时不会由于工作部210温度过高而导致上泵壳140变形；下泵壳150需要承担安装叶轮组件300和封闭腔体110的作用，不需要承受很高温度，故而下泵壳150可以采用塑料材质制作，举例来讲，下泵壳150可以采用聚氨酯塑料或者环氧塑料，等等；塑料材质的下泵壳150利于加工，且成本低廉。
具体而言，上泵壳140可以采用铝材制作，铝材压铸可以相对容易生产出复杂形状，以便将上泵壳140上的结构一体成型，且导热性能佳，制作时，将加热件200放置于模具，然后与铝材一体压铸成型；当然，上泵壳140还可以采用铜或者别的金属材料制作，均可以起到快速导热和耐高温的作用。
需要说明的是，腔体110和叶轮组件300的安装实施方式并不局限于上述的实施例，腔体110和叶轮组件300的设置位置可以对调，即腔体110可以设置在下泵壳150内，进水口120和出水口130均设置在下泵壳150，叶轮组件300可以安装在上泵壳140内，下泵壳150采用金属材料与加热件200一体压铸成型，上泵壳140采用塑料材质，以便降低加工难度和材料成本，等等，此实施方式亦可以实现同样功能。
此外，本领域技术人员可以理解的是，壳体100并不局限于分成两部分制作，在本公开一些实施例中，壳体100也可以整体一体式制造，以便减少装配工序，提高整体结构强度。
如图1、图2和图5所示，在本公开的一些实施例中，上泵壳140内的腔体110大致呈圆桶状，腔体110的深度呈变化状态，腔体110的底部朝内部凹陷，具体而言，腔体的底面的中间部分呈平面状，腔体的底面的其余部分呈圆锥面状，叶轮组件300为离心式结构，从位于腔体110内的那部分叶轮组件300的最大外径处到腔体110的侧壁，腔体110的深度逐渐增加，此实施例中，被叶轮组件300驱动的液体在离开叶轮组件300后，供液体流通的横截面逐渐变大，可以减缓液体流动速度，以便液体稳定过渡，更加符合流体设计原理，减少紊流的产生，有利于提高水力效率。
具体而言，腔体110的底面的中间部分设置有通孔160，进水口120通过一段弯曲的管道与通孔160连接，进而实现与腔体110连通，进水口120和出水口130朝向平行设置，方便工作人员在同一工位进行管路连接，减少工作人员来回走动，提高工作效率。
为了贴近腔体110，加热件200呈倒三角螺旋结构，加热件200位于腔体的底面中呈圆锥面状的部分内，加热件200为加热管盘绕而成，至少具有两圈，以便能够均匀加热上泵壳140。需要说明的是，加热管绕圈的圈数根据腔体110的直径大小设置，越大的腔体110，加热管绕圈的圈数越多，与上泵壳140接触面积也越多，使得加热更为均匀、高效。
如图6所示，在本公开的一些实施例中，上泵壳140内的腔体110大致呈圆桶状，腔体110的深度呈变化状态，腔体110的底部朝外凸起，具体而言，腔体110的底面的中间部分呈平面状，腔体110的底面的其余部分呈圆锥面状，叶轮组件300为离心式结构，从位于腔体110内的那部分叶轮组件300的最大外径处到腔体110的侧壁，腔体110的深度逐渐减少。在腔体110的边缘高度不变的情况下，此实施例可以增大腔体110内部的空间，使得腔体110的有效容纳空间增大。
具体而言，腔体110的底面的中间部分设置有通孔160，进水口120通过一段弯曲的管道170与通孔160连接，进而实现与腔体110连通，进水口120和出水口130朝向平行设置，方便工作人员在同一工位进行管路连接，减少工作人员来回走动，提高工作效率。
如图7所示，为了贴近腔体110，加热件200呈三角螺旋结构，加热件200位于腔体110的底面中呈圆锥面状的部分内，加热件200为加热管盘绕而成，至少具有两圈，以便能够均匀加热上泵壳140。需要说明的是，加热管绕圈的圈数根据腔体110的直径大小设置，越大的腔体110，加热管绕圈的圈数越多，与上泵壳140接触面积也越多，使得加热更为均匀、高效。
如图8所示，在本公开的一些实施例中，上泵壳140内的腔体110呈圆柱体状，腔体110的深度一致。此实施例可以兼顾流体的流动性能和腔体110的空间利用率，非常实用。
举例来讲，腔体110的底面的中间位置设置有通孔160，进水口120通过一段弯曲的管道170与通孔160连接，进而实现与腔体110连通，进水口120和出水口130朝向平行设置，方便工作人员在同一工位进行管路连接，减少工作人员来回走动，提高工作效率。
如图9所示，为了贴近腔体110，加热件200呈圆盘状结构，加热件200位于腔体110的底面内，加热件200为加热管盘绕而成，至少具有两圈，以便能够均匀加热上泵壳140。需要说明的是，加热管绕圈的圈数根据腔体110的直径大小设置，越大的腔体110，加热管绕圈的圈数越多，与上泵壳140接触面积也越多，使得加热更为均匀、高效。
如图2至图4所示，在本公开的一些实施例中，下泵壳150上凸出设置有挡板400，在 上泵壳140和下泵壳150组装好以后，挡板400位于腔体110内，挡板400朝向叶轮组件300的内侧面410呈渐开螺旋状，以引导被叶轮驱动的流体的流动，减少紊流的产生，有利于提高水力效率。
其中，挡板400可以与下泵壳150一体成型制造，也可以分别独立制造以后再组装。
如图2至图4所示，由于挡板400位于腔体110内，距离加热件200相对较近，当挡板400采用塑料材质时，需要考虑加热件200对挡板400的温度影响。为此，在本公开的一些实施例中，挡板400远离叶轮组件300的外侧面420与腔体110的内侧壁之间具有间隙S，挡板400距离加热件200越近，间隙S越大，挡板400距离加热件200越远，间隙S越小，当间隙S很大时，从间隙S处流经的流体越多，可以带走更多的热量，防止挡板400温度过高而变形，保障挡板400的使用寿命，当挡板400距离加热件200很远时，此处的散热需求不高，进而不需要很大流量，故而不需要很大间隙。
此外，为了避免液体在进出到间隙S时产生紊流，在挡板400的两端均设置有斜面，通过斜面引导液体进入到间隙S内，可以有效减少液体在进出间隙S时产生紊流的现象，提高整体的水力效率。挡板400的顶部也采用曲面圆滑过渡，减少液体在流经此处时产生紊流的现象，可以进一步提高整体的水力效率。
在某些使用场景中，腔体110内流经的流体具有一定的腐蚀性，为了保障壳体100的使用寿命，在腔体110的内侧壁上设置有涂层，以防止流体直接与壳体100接触。具体而言，上泵壳140采用金属材料制作时，需要在上泵壳140的腔体110的内侧壁上设置涂层。涂层具体可以采用聚四氟乙烯材料(特氟龙)，聚四氟乙烯具有抗酸抗碱、抗各种有机溶剂的特点，可以有效保护上泵壳140不被流体腐蚀。
当然，本领域技术人员可以理解的是，涂层的具体实施方式并不局限于上述的聚四氟乙烯材料，其还可以采用其它实施例，例如，涂层还可以采用环氧树脂材料，等等。
如图2、图6、图8所示，在本公开的一些实施例中，叶轮组件300包括半开式叶轮及电机310，半开式叶轮位于腔体110，电机310安装在下泵壳150内，半开式叶轮包括底板320和多个叶片330，底板320下侧设置有螺纹孔，螺纹孔与电机310的转轴螺纹连接，叶片330安装在底板320上侧，多个叶片330呈环状分布，通孔160与电机310的转轴对齐，进水口通过转角为90°的管道170与通孔160连通，出水口130的中心线垂直于电机的转轴，从进水口120进入的水通过管道170引导转向后，沿电机转轴方向进入到叶片330之间，被底板320阻挡，然后被转动的叶片330带动转动，在离心力的作用下往外移动，经过挡板400的引导，从出水口130中排出；如此设置可以较大程度的将从进水口120进来的流体快速驱动到出水口130，提高整体的水力效率。
上述的加热泵具体工作原理如下：加热泵启动后，液体从进水口120进入，流经管道170，在管道170的引导下，液体流动方向改变为与电机310的转轴同向，液体从通孔160进入到腔体110内，加热件200对腔体110内的水进行加热，经过加热的水在叶片330的驱动下，以离心式的方式离开叶片330的范围，经过挡板400的引导，从出水口130中排出。
本公开还提供一种洗碗机，包括上述任一实施例的加热泵。上述洗碗机中的加热泵通过将加热件200与壳体100一体压铸成型，利用壳体100现有空间容纳加热体，可以减少整体空间占比，提高空间利用率，利于产品小型化；同时减少将加热件200装配到壳体100上的装配工序，提高装配效率。由于加热泵的体积可以减少，故而其在洗碗机上所需的安装空间也相应减少，进而可以提高洗碗机的有效容量。
上面结合附图对本公开实施例作了详细说明，但是本公开不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本公开宗旨的前提下作出各种变化。
