具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
相关技术中，洗碗机从申请到如今已有100年左右的历史，其主要功能是为了自动清洗餐具设备。通常具有洗涤、消毒、烘干等功能，为了有效地融油和除菌，往往需要将洗涤的水温加热到72℃左右，因此需要在水泵内或者其它洗碗机底部空间内分体地增加加热装置。而现代洗碗机越来越紧凑化的设计往往要求泵和加热装置做成一体结构，形成加热泵的结构需求。
相关技术中的方案存在以下缺点：其一，体积大：由于考虑热安全性的要求，发热管和泵壳通常留有较大的距离，因此造成了泵壳的外径增加，而洗碗机通常考虑有效容积率，往往要求水泵安装具有更小的高度，这种方案和洗碗机往大容积率的方向存在一定矛盾。其二，现有在泵壳内加热的方案，加热管和塑料叶轮以及蜗壳距离较近且无隔离，在热辐射的作用下容易导致水泵叶轮及蜗壳老化。其三，现有方案加热管往往不至于叶轮后部，而水流往往是径向往泵壳壁面运动，容易造成加热管表面的流速低，导致加热管表面雷诺数过低，进而产生表面换热不充分的现象。
下面参考附图描述根据本申请实施例的加热泵100。所述加热泵100上设有出口加热装置。
参照图1，根据本申请第一方面实施例的加热泵100，包括：驱动电机1、泵壳2、叶轮3以及加热件4。
具体而言，结合图2、3、4和图11，泵壳2内限定有泵腔21和连通泵腔21的加热腔22，泵腔21与加热腔22大致呈轴向并排布置，泵腔21和加热腔22适于通过连通通道23相连通，泵壳2上形成有连通泵腔21的进水口51和连通加热腔22的出水口24。
例如，泵壳2内可以限定有泵腔21和加热腔22，加热腔22可以连通泵腔21设置，泵腔21与加热腔22大致呈轴向并排布置，泵腔21的轴线与加热腔22的轴线平行，并且泵腔21的轴线与加热腔22的轴线可以间隔开设置。这样相当于降低了加热泵100的整体高度，从而有利于缩小加热泵100的体积。
在本申请的一些实施例中，泵腔21和加热腔22可以通过连通通道23相连通，泵壳2上可以形成有出水口24，出水口24可以连通加热腔22。
叶轮3设在泵腔21内，叶轮3与驱动电机1的电机轴11相连。例如，叶轮3可以为例如塑料件等，叶轮3可以为例如离心叶轮等，叶轮3可以设在泵腔21内，叶轮3可以与驱动电机1的电机轴11相连。由此，通过驱动电机1可以驱动叶轮3旋转。
加热件4可以设在加热腔22内。这样通过在加热腔22内设置加热件4，可以对流经加热腔22的水流进行加热。
根据本申请实施例的加热泵100，采用加热腔22基本与泵腔21(叶轮3设在泵腔21内)轴向并排布置的设计结构，并且，加热腔22与泵腔21之间通过连通通道23进行连接，由此，不仅有利于缩小加热泵100的体积，还可以避免加热件4的高温辐射叶轮3，因此，不会出现由于加热件4的热辐射导致叶轮3出现过早的老化现象而影响加热泵100的性能。
其中，由进水口51进入泵腔21的水流可以经由连通通道23进一步流入加热腔22内，进入加热腔22内的水流可以由加热件4进行加热，从而能够由出水口24输出经加热件4加热后的水流，更好地满足用户的需求。
根据本申请实施例的加热泵100，通过使泵腔21大致与加热腔22轴向并排布置，叶轮3设在泵腔21内，并且加热腔22与泵腔21之间通过连通通道23相连通，由此，不仅有利于缩小加热泵100的体积，还可以避免加热件4的高温辐射叶轮3，从而能够防止叶轮3出现过早的老化现象，进而可以提高加热泵100的使用性能。
参照图16和图18，根据本申请的一些实施例，连通通道23被构造成沿泵壳2的内壁面的切向延伸。例如，在本申请的一些具体实施例中，连通通道23可以被构造成沿泵壳2的内壁面的切向延伸。由此，一方面便于将叶轮3吸入的气泡顺利导入到加热腔22而不聚集在泵腔21内，避免发生气泡的噪音。另一方面，可以将水流高速导入加热腔22，并使水流沿着加热腔22的壁面旋绕，便于加热件4换热性能的提高。
当然，在本申请的一些实施例中，连通通道23也可以不采用切向延伸的方式设置，本申请对连通通道23的具体延伸方式不作限定，实际应用中可以根据需要而适应性设置。
进一步地，结合图4和图9，在水流的流动方向上，连通通道23被构造成扩张通道，且所述扩张通道的扩张角度不大于20度。例如，在水流的流动方向上，相距距离L取垂直于水流的流动方向的两个截面，其中，记位于上游侧的截面的当量直径为D1，记位于下游侧的截面的当量直径为D2，则有：扩张角度α＝2*arctan(D2-D1)/L，即扩张角度的一半的正切值等于(D2-D1)/L。
参照图15和图16并结合图14，根据本申请的一些实施例，在水流的流动方向上，泵腔21包括：进口连接段211以及水泵蜗壳212，水泵蜗壳212与加热腔22之间形成所述扩张通道23。由此，通过在加热腔22和水泵蜗壳212之间设置了一个扩张通道，可以进一步回收水泵蜗壳212出口的动压，提高加热泵100的扬程，同时进入加热腔22速度的降低有利于降低水流进入加热腔22的损失系数，从而可以提高加热泵100的效 率。
参照图2并结合图1，在本申请的一些实施例中，泵壳2上设有连通加热腔22的出口接管25，出口接管25的自由端形成出水口24。例如，泵壳2上可以设有出口接管25，出口接管25可以连通加热腔22设置，出口接管25的自由端可以形成出水口24。由此，通过出口接管25便于外接管路，使得由加热件4加热后的水流可以经由出口接管25再由出水口24进一步流出。
进一步地，参照图3和图5，出口接管25被构造成沿加热腔22的外侧壁的切向延伸。例如，在本申请的一些实施例中，出口接管25可以被构造成沿加热腔22的外侧壁的切向延伸。由此，通过将切向的出口接管25和切向的扩张通道配合可以形成发热腔进口的强旋流，这样有利于达到更好地去除气泡的效果。
根据本申请实施例的加热泵100，通过将切向的出口接管25和切向的扩张通道配合可以形成发热腔进口的强旋流，从而可以进一步避免发热腔22内气泡聚集产生的异常噪音和干烧现象。
当然，本申请不限于此，在本申请的一些实施例中，出口接管25也可以不采用沿加热腔22的外侧壁的切向延伸，那样也可以形成一定的旋流。
参照图2并结合图1，根据本申请的一些实施例，加热腔22上设有与加热件4电连接的接线端子221，以连接外部的供电电路。例如，加热腔22上可以设有接线端子221，接线端子221可以与加热件4电连接，接线端子221可以设在加热腔22的外侧壁，通过接线端子221便于连接外部的供电电路，便于进一步实现对水流的加热。
进一步地，参照图2和图15，加热腔22的底部形成有第一安装槽212，第一安装槽212内设有第一密封件6。例如，加热腔22的底部可以形成有第一安装槽212，第一安装槽212内可以设有第一密封件6，所述第一密封件6可以为例如密封圈或密封垫等，由此，通过在第一安装槽212内设置第一密封件6，可以实现加热腔22的密封连接，从而能够防止加热腔22漏水。
参照图1和图2，根据本申请的一些实施例，加热件4为螺旋延伸的发热管，且所述发热管的旋向被构造成与水流的流动方向一致。例如，在本申请的一些实施例中，加热件4可以为发热管，所述发热管可以螺旋延伸，并且所述发热管的旋向被构造成与水流的流动方向一致。由此，使得进入加热腔22内的水流可以沿着加热腔22的壁面运动，从而可以形成旋流，该旋流可以阻止气泡在加热腔22内的聚集，还可以避免加热腔22内气泡聚集产生的异常噪音和干烧现象，有利于延长所述发热管的寿命。
例如，在本申请的一些实施例中，加热腔22内匹配的所述发热管的设计可以和水流的旋向(例如，水流的流动方向)一致，例如，从驱动电机侧看所述发热管可以是顺时 针旋绕的。
根据本申请实施例的加热泵100，泵腔21(例如水泵蜗壳212)和加热腔22可以通过连通通道23例如扩张通道相连通，由此，使得经由所述扩张通道流入加热腔22的水流会沿着加热腔22的壁面运动，从而可以形成旋流，该旋流可以阻止气泡在加热腔22内的聚集，还可以避免加热腔22内气泡聚集产生的异常噪音和干烧现象，有利于延长所述发热管的寿命。
当然，本申请不限于此，在本申请的一些实施例中，加热件4也可以采用不同于所述发热管的结构形式。在本申请的一些实施例中，加热件4可以为设在加热腔22的内壁面的厚膜(图中未示出)。例如，加热件4可以为厚膜，所述厚膜可以设在加热腔22的内壁面。由此，通过所述厚膜也可以实现对流入加热腔22内的水流的加热。
根据本申请的一些实施例，加热腔22的内壁面设有导流筋，且所述导流筋的延伸方向被构造成与水流的流动方向一致。例如，加热腔22的内壁面可以设有导流筋，并且所述导流筋的延伸方向可以被构造成与水流的流动方向一致。由此，通过在加热腔22的内壁面设置所述导流筋有利于增强水流的旋绕效果。
例如，所述导流筋可以为螺旋延伸的一体式结构，或者，所述导流筋可以包括分体设置的多个，多个导流筋的延伸方式可以与水流的流动方向保持一致等。
根据本申请的一些实施例，电机轴11上形成有外螺纹，叶轮3上形成有内螺纹，所述外螺纹与所述内螺纹相匹配以使电机轴11与叶轮3螺纹连接，其中，所述外螺纹与所述内螺纹的旋转向可以相同，所述外螺纹/所述内螺纹的旋向与驱动电机1的旋转方向相反。由此，通过所述外螺纹和所述内螺纹的配合可以实现驱动电机1与叶轮3之间的装配连接，通过使所述外螺纹/所述内螺纹的旋向与驱动电机1的旋转方向相反，可以进一步保证驱动电机1与叶轮3之间的装配可靠性。
参照图2，在本申请的一些实施例中，加热泵100还可以包括端盖5，端盖5上形成有所述进水口51，且端盖5与泵壳2密封连接。例如，在本申请的一些实施例中，端盖5上可以形成有所述进水口51，进水口51可以连通泵腔21设置，并且端盖5与泵壳2密封连接。由此，可以保证端盖5与泵壳2之间的密封性能，从而能够防止漏水，提高加热泵100的使用性能。
根据本申请的一些实施例，参照图6，端盖5与泵壳2可拆卸连接。由此，通过使端盖5与泵壳2可拆卸连接，便于实现端盖5与泵壳2之间的装配和拆卸，有利于加热泵100的维修保养。
例如，在本申请的一些实施例中，端盖5与泵壳2可以采用例如螺钉连接等方式相连；但本申请不限于此，在本申请的一些实施例中，端盖5与泵壳2也可以采用卡扣连 接的方式相连等。
进一步地，参照图20和图21，端盖5可以包括：进水端盖52以及出水端盖53。
具体而言，结合图2，进水端盖52与泵壳2之间可以设有第二密封件7；出水端盖53与泵壳2之间可以设有第三密封件8。示例性且不限制地，第二密封件7和第三密封件8可以为例如O型密封圈等。
其中，参照图20和图21，进水端盖52上可以形成有配合槽521，泵壳2上形成有配合部26(参照图15)，配合部26与配合槽521相匹配，配合部26上可以形成有第二安装槽261，第二安装槽261内适于安装第二密封件7，出水端盖53上可以形成有第三安装槽531，第三安装槽531内适于安装第三密封件8。由此，通过在第二安装槽261内安装第二密封件7有利于实现进水端盖52与泵壳2之间的密封连接，通过在第三安装槽531内安装第三密封件8有利于实现出水端盖53与泵壳2之间的密封连接，这样能够防止漏水，保证加热泵100的使用可靠性。
参照图21并结合图2，在本申请的一些实施例中，在水流的流动方向上，端盖5(例如进水端盖52)的内侧限定有进水通道54、整流通道55以及配合通道56，进水通道54的入水端形成所述进水口51，叶轮3设在配合通道56处且与配合通道56的内壁面间隔开设置，以在叶轮3与配合通道56之间限定出适于回流水流的回流通道9。
例如，在水流的流动方向上，端盖5的内侧可以限定有进水通道54、整流通道55以及配合通道56，进水通道54的入水端可以形成所述进水口51，整流通道55用于与叶轮3对接，叶轮3可以设在配合通道56处，并且叶轮3与配合通道56的内壁面可以间隔开设置，这样可以在叶轮3与配合通道56之间限定出适于回流水流的回流通道9。
根据本申请实施例的加热泵100，由于加工工艺的原因，可能会存在水流的回流现象，因此，配合通道56的主要作用是和叶轮3匹配形成狭小的回流通道9，这样可以抑制回流量，从而有利于提高加热泵100的效率。
进一步地，结合图21，进水通道54的外壁面形成有密封凸起541以连接进水软管。例如，进水通道54的外壁面可以形成有密封凸起541，密封凸起541可以呈环形，密封凸起541可以包括多个，多个密封凸起541可以沿进水通道54的延伸方向间隔开设置，通过密封凸起541便于连接进水软管。
在本申请的一些实施例中，结合图2，出水接管25的外壁面也可以形成有相应的密封凸起，这样便于通过所述密封凸起连接出水软管。
参照图21并结合图2，在本申请的一些实施例中，在水流的流动方向上，整流通道55的内壁面被构造成径向尺寸逐渐收缩的形状。例如，在本申请的一些实施例中，在水流的流动方向上，整流通道55的内壁面被构造成径向尺寸逐渐收缩的形状。由此，通 过所述整流通道55有利于整流，稳定水流。
进一步地，整流通道55的内壁面被构造成锥形或弧形。例如，在图21中所示的本申请的实施例中，整流通道55的内壁面可以被构造成弧形。当然，本申请不限于此，在本申请的一些实施例中，整流通道55的内壁面也可以被构造成锥形。
在本申请的一些实施例中，端盖5为一体式结构或分体式结构。例如，在本申请的一些实施例中，端盖5可以为一体式结构；当然，在本申请的一些实施例中，端盖5也可以为分体式结构。本申请对端盖5的具体成型方式不作限定，实际应用中可以根据需要适应性设置。
下面结合附图描述根据本申请的加热泵100的具体实施例。
根据本申请实施例的加热泵100的结构如图1-图10所示，其中，图1是根据本申请实施例的加热泵100的一个示意图；图2是沿图1中A-A线的剖视图；图3是沿图1中B-B线的剖视图；图4是沿图1中C-C线的剖视图；图5是沿图1中D-D线的剖视图；图6是图1中根据本申请实施例的加热泵100的另一个示意图；图7是图1中根据本申请实施例的加热泵100的再一个示意图；图8是沿图7中E-E线的剖视图；图9是沿图7中F-F线的剖视图；图10是图1中根据本申请实施例的加热泵100的还一个示意图。
加热泵100包括：驱动电机1、泵壳2、叶轮3、接线端子221、加热件4(例如发热管或厚膜等)、第一密封件6、第二密封件7(例如O型圈等)、第三密封件8(例如O型圈等)以及端盖5等零部件。驱动电机1和叶轮3可以通过叶轮3的内螺纹和电机轴11的外螺纹进行连接，其中，所述内螺纹和所述外螺纹的旋向可以相同，所述内螺纹/外螺纹的旋向和驱动电机1的旋向相反以保证工作时不会脱落，叶轮3由驱动电机1驱动；泵壳2为两个腔体结构，泵壳2内可以限定有泵腔21和加热腔22，泵腔21和加热腔22之间通过连通通道23(例如扩张通道)将水泵蜗壳212和加热腔22连接。泵壳2下端和发热管的接线端子221可以通过螺栓连接，且在加热腔22上形成有第一安装槽212(例如凹型结构)用于安装第一密封件6(例如密封垫圈)，以防止水泄漏。端盖5和泵壳2可以通过螺钉连接，并且在端盖5和泵壳2之间可以设置有第二密封件7和第三密封件8，防止水从端盖5处泄漏，例如，进水端盖52与泵壳2之间可以设有第二密封件7，出水端盖53与泵壳2之间可以设有第三密封件8。
水通过端盖5外侧带有密封凸起541的进水通道54(例如吸水接管)进入加热泵100，随后通过一个整流通道55进入叶轮3，整流通道55的设置有利于整流，经过叶轮3的做功加压，高速水流再进入到水泵蜗壳212内进行收集，然后通过一个切向的连通通道23(例如扩张通道)进入加热腔22，进入加热腔22的水由于是以切向方式进入，因此 主要水流会沿着壁面旋绕，并且高速地绕过旋向和水流旋向一致的发热管，最后旋绕一周加热后的水流可以通过切向的出口连接管25导出加热泵100。
泵壳2的结构详图如图11-图17所示，其中，图11是图1中根据本申请实施例的加热泵100中泵壳2的一个立体图；图12是图1中根据本申请实施例的加热泵100中泵壳2的另一个立体图；图13是图1中根据本申请实施例的加热泵100中泵壳2的一个示意图；图14是图1中根据本申请实施例的加热泵100中泵壳2的另一个示意图；图15是沿图14中G-G线的剖视图；图16是沿图14中H-H线的剖视图；图17是图1中根据本申请实施例的加热泵100中泵壳2的再一个示意图；图18是沿图17中I-I线的剖视图；图19是沿图17中J-J线的剖视图。
泵壳2主要包括：进口连接段211、水泵蜗壳212、连通通道23(例如扩张通道)、加热腔22、出口连接管25和第一安装槽212等。其中，进口连接段211将进口接管套住，通常为一直管。连通通道23例如扩张通道的作用是为了连接水泵蜗壳212和加热腔22，结构上布置在加热泵100的切向(靠近顶部)位置，这种设计主要的考虑是便于将叶轮3吸入的气泡顺利导入到加热腔22而不聚集在水泵蜗壳212内，避免发生气泡的噪音。连通通道23例如扩张通道的切向方式进入加热腔22的还一个考虑是将水流高速导入加热腔22，并使水流沿着加热腔22的壁面旋绕，便于发热管换热性能的提高，连通通道23例如扩张通道的结构为扩张型，在水流的流动方向上，从上游侧到下游侧逐渐增加，通常要求扩张度不大于20°以避免扩张太大带来损失。加热腔22的设置特点是基本与泵腔22(叶轮3设在泵腔22内)轴向并排布置，加热腔22底部形成有第一安装槽212，第一安装槽212用于安装第一密封件6例如密封垫，这样可以对加热件4例如发热管等和接线端子221进行内外密封。在加热腔22内部设置有发热管，由于所述发热管的高温只能辐射加热腔22而不会影响叶轮3，因此不会出现由于所述发热管的热辐射导致塑料的叶轮3出现过早的老化现象而影响加热泵100的性能。由于连通通道23例如扩张通道是从顶部进入加热腔22，因此所述发热管的设计通常和水流的旋向一致，即从驱动电机侧看所述发热管是顺时针旋绕的。最后，旋转一周的水流通过切向的出口连接管25将水流导出加热泵100，出口连接管25的设置最好设置在加热腔22的顶部。其目的主要是将进入加热腔22的气泡顺利排出加热腔22从而避免产生气泡的噪音，同时气泡的存在还会影响所述发热管的换热，严重时会导致干烧现象产生破坏。
端盖5的结构如图20-图21所示，其中，图20是图1中根据本申请实施例的加热泵100中端盖5的一个立体图；图21是图20中根据本申请实施例的加热泵100中端盖5的一个剖视图。端盖5的主要作用是连接进水管和密封加热腔22，端盖5的结构可以是一体结构，也可以是分开为进水端盖52和出水端盖53的两个端盖。端盖5主要包括： 进水通道54、整流通道55、配合通道56、进水端盖52及设在进水端盖52上的配合槽521、出水端盖53及设在出水端盖53上的第三安装槽531。
进水通道54的外侧带有密封凸起541结构用于连接进水软管，整流通道55则是一段收缩段，主要用于稳定水流设置，并和叶轮3对对接。配合通道56主要和叶轮3外侧形成回流通道9，由于这种小型的加热泵通常由于加工工艺的原因，会存在一定的水流的回流现象，因此配合通道56的主要作用是和叶轮3匹配形成狭小的回流通道9，抑制回流量，提高加热泵100的效率。出水端盖53主要是密封发热管一侧水流，并在端盖内部加工出第三安装槽531，配合第三密封件8例如O型圈对加热腔22进行密封。
根据本申请实施例的加热泵100，可被用于洗碗机、洗衣机、烘干机、洗干一体机等多种需要加热液体的装置中，通过加热泵100的介质可以是水或者带有泡沫的液体。本领域技术人员应当知晓，本申请实施例的加热泵100所应用的场景不对加热泵100本身的结构造成限定。根据实际应用的需要，加热泵100的出口和进口可以与加热泵100外部的管道连接。
需要说明的是，本申请实施例所称的物体的纵截面指的与该物体的对称轴平行的截面，横截面指的是垂直于对称轴的截面。
如图22所示，加热泵100包括泵壳2、叶轮3和加热件4。泵壳2内部形成泵腔21、泵腔的水泵蜗壳212(例如集液腔)和加热腔22，叶轮3的入液口连通泵腔21，叶轮3的出液口连通泵腔的水泵蜗壳212，泵腔的水泵蜗壳212到加热腔22由连通通道23连通，加热件4设置在加热腔22内，加热腔22设置有出口接管25，出口接管25内限定出出口通道，出口接管25的自由端形成有出水口24。流体通过泵腔21进入叶轮3，经过叶轮3的离心加压后，流体经过叶轮3的出口流入泵腔的水泵蜗壳212。泵腔的水泵蜗壳212中的流体由连通通道23流入加热腔22，并在加热腔22中被加热件4加热后流入出水口24。
叶轮3设置于泵腔21和泵腔的水泵蜗壳212之间，加热件4设置于加热腔22中，通过将叶轮3和加热件4设置于不同的腔室中，从而无需在泵壳2中设置体积较大的容纳叶轮3和加热件4的腔体，并且叶轮3和加热件4二者所在腔室具有连通通道23的隔离，从而避免加热件4的高温辐射叶轮3，避免了叶轮3的过早老化。
在本申请的一些实施例中，如图22所示，叶轮3与驱动装置连接，由所述驱动装置驱动旋转从而对流经叶轮3的流体离心加压做功，提升流体的速度。驱动装置可与泵壳2固定，驱动装置可以为例如驱动电机1，驱动电机1和叶轮3可以通过叶轮3的内螺纹与驱动电机1的输出轴(例如电机轴11)的一端连接，叶轮3的旋转方向与驱动电 机1的旋转方向相反以确保叶轮3工作时不会脱落。叶轮3的叶片形状、数量、间距等可以根据实际需要进行设计。
在一些实施例中，如图23所示，连通通道23的轴线与加热腔22的轴线垂直，且连通通道23的轴线与加热腔22的轴线不在同一个平面内，加热腔22类似为圆筒形。流体由连通通道23进入加热腔22时，流体的动压力被转化为两个方向上的力，在加热腔22的壁面的法线方向上，流体的动压力被转化为对加热腔22的壁面的静压力；在加热腔22的壁面的切线方向上，流体的动压力被转化为驱动力，该驱动力驱动流体沿加热腔22的壁面旋转流动，从而形成绕加热件4的旋流，避免了加热不均和干烧现象，提升了加热效率和加热件4的寿命。
在一些实施例中，如图23所示，连通通道23的横截面面积沿泵腔的水泵蜗壳212到加热腔22的方向增大。在流体的流量不变的前提下，截面面积与流体的流速呈反比，通过增大沿泵腔的水泵蜗壳212至加热腔22的连通通道23的横截面积，降低流体流入加热腔22时的流速，回收了流体的动压，进而增加了加热泵100的扬程。同时，降低流体流入加热腔22时的流速，还能够降低流体的动能损失，进一步增强水流的旋绕效果，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，连通通道23的横截面积沿泵腔的水泵蜗壳212到加热腔22的方向连续均匀增大，避免由于截面突变导致流体的动能的损失，进一步增强水流的旋绕效果，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，如图23所示，连通通道23的纵截面为轴对称形状，以便于连通通道23的加工，同时，沿泵腔的水泵蜗壳212到加热腔22的方向，连通通道23的横截面积的增大量小于一定的阈值，具体来说，连通通道23的纵截面的两侧边的夹角小于预设值，该预设值例如可以为20°，能够保证由泵腔的水泵蜗壳212到加热腔22的方向，连通通道23的横截面面积的增大量小于一定的阈值，从而保证流体流入加热腔22时流速大于一定的阈值，保证流体与加热腔22的壁面不发生分离，进一步增强流体的旋绕效果，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，在连通通道23的横截面内，外壁面142与加热腔22的壁面相切，在离心力的作用下，流体由泵腔的水泵蜗壳212流入加热腔22时，沿连通通道23的外壁面142流动，并沿切向流入加热腔22中，流体的动压力全部被转化为驱动流体沿加热腔22的壁面旋转流动的驱动力，进一步增强水流的旋绕效果，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，如图23所示，泵壳2具有形成连通通道23的内壁面141和外壁面142，其中，内壁面141和外壁面142均为与连通通道23内的流体接触的面，并非与 外部环境接触的面，以距离泵腔21的轴线较远的壁为外壁面142，以距离泵腔21的轴线较近的壁为内壁面141。内壁面141和外壁面142在连通通道23的纵截面中对应截面的两侧边。内壁面141和/或外壁面142的壁面均为平面，即，内壁面141和/或外壁面142与流体接触的内表面不存在任何凸起或凹槽。在一些实施例中，外壁面142的内表面与叶轮3的轴线垂直。从泵腔的水泵蜗壳212流到连通通道23的液体的流向与外壁面142的壁面方向一致，壁面为平面的情况下，流体发生分离的几率减小，流动方向保持不变。
流体由泵腔的水泵蜗壳212通过内壁面141和外壁面142形成的连通通道23流入加热腔22时，流体的动能发生沿程损失，具体来说，流体的沿程损失是指，由于流体与内壁面141和外壁面142之间的摩擦力，流体的动能转化为内壁面141和外壁面142的内能，流体的动能发生损失。内壁面141和外壁面142在横截面中为直线，使流体沿直线由泵腔的水泵蜗壳212流入加热腔22中，减小了流体沿内壁面141和外壁面142流动时的运动行程，减小了该摩擦力做功的大小，进而减小了流体通过连通通道23流入加热腔22时，流体的动能的沿程损失。
流体由泵腔的水泵蜗壳212通过连通通道23流入加热腔22时，流体的动能发生局部损失，具体来说，液体流经的连通通道23发生截面突变时，流体的动能会发生损失。内壁面141和外壁面142与流体接触的内表面不存在任何凸起或凹槽，避免连通通道23发生截面突变，避免流体通过连通通道23流入加热腔22时，流体的动能的局部损失。
通过将连通通道23的侧壁内表面设置为平面，减小了流体连通通道23流入加热腔22时，流体的动能的沿程损失和局部损失，增强了流体在加热腔22中绕加热件4的旋流，使流体的受热更加均匀，进一步避免了加热不均和干烧现象。
在一些实施例中，如图23所示，泵壳2还包括将泵腔21、叶轮3和泵腔的水泵蜗壳212形成的整体与加热腔22分隔的间隔壁16。设置间隔壁16将容纳叶轮3的泵腔21和泵腔的水泵蜗壳212与容纳加热件4的加热腔22分隔，能够防止加热腔22中的加热件4的热辐射作用于叶轮3，从而避免叶轮3受热老化，延长叶轮3的使用寿命。
在一些实施例中，如图22所示，连通通道23与加热腔22的顶部开口连通，顶部开口设置在间隔壁16和加热腔22的第一端之间。即，顶部开口为靠近加热腔22端部的开口，加热腔22的进口与连通通道23相对，能够将叶轮3转动时产生的流体中的气泡导入加热腔22中，防止气泡在泵腔的水泵蜗壳212中聚集导致噪声，并且流体由加热腔22的一端进入将沿加热腔22的壁面运动，进而旋转流动，避免了气泡在加热腔22内的聚集，从而避免异常噪音和干烧现象。
在一些实施例中，如图23所示，间隔壁16还包括引导出液口的液体流向泵腔的水 泵蜗壳212的引导件161，引导件161形成连通通道23的内壁面141，即，连通通道23的内壁面与间隔壁16连接为一体，将间隔壁16和连通通道23的内壁面141集成为整体，简化了加热泵100的内部结构，降低了加热泵100的制造成本，减小了加热泵100的体积。经过叶轮3出口流出的液体受到内壁面141的阻挡及导向，流入泵腔的水泵蜗壳212内，然后通过内壁面141和外壁面142形成的连通通道23流入到加热腔12中。
在一些实施例中，如图22所示，泵腔21和加热腔22的轴线平行，即：上述泵腔21和加热腔22两个腔并排设置，从而便于加热泵100的加工和安装。
在一些实施例中，如图22所示，加热件4从加热腔22的第一端向相对的第二端延伸，出水口24设置在加热腔22的第二端。流体由加热腔22的第一端进入加热腔22中，并在加热腔22中产生旋流，旋流绕加热件4被加热后，流过整个加热腔22，由加热腔22的第二端流入出水口24，然后流出。出水口24设置在加热腔22的第二端，使得流体在加热腔22中与加热件4充分接触，并配合切向的连通通道23，形成加热腔22进口的强旋流，进一步避免加热腔22内的气泡聚集。需要说明的是，出水口24也可以设置在加热腔22的其他位置，距离进入加热腔22的第一端一定间距，而并不一定要设置在加热腔22的第二端。
出口接管25的轴线与加热腔22的轴线垂直，可形成出口接管25的壁面与加热腔22的壁面相切，流体沿加热腔22的壁面的切向流入出水口24，流体从加热腔22切向流出与流体从加热腔22切向流入配合形成进入加热腔22进口的强旋流，进一步避免加热腔22内气泡聚集产生异常噪音，以及避免干烧现象。
在一些实施例中，如图22所示，在一些实施例中，加热件4为螺旋发热管，该螺旋发热管从加热腔22的第一端延伸至相对的第二端，从加热腔30的第一端向第二端看，该螺旋发热管沿顺时针方向缠绕。即，螺旋发热管的缠绕方向与流体在加热腔22中的旋转方向一致，能够增强水流的旋绕效果，并使流体更加充分地与该螺旋发热管接触，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，如图22所示，出口接管25的轴线与加热件4的延伸方向垂直，有利于流体在加热腔22中形成旋流。流体在加热腔22内沿着壁面绕加热腔22的轴线旋转流动，沿加热腔22的壁面流入出水口24，然后流出加热泵100。
在一些实施例中，如图22所示，加热腔22从第一端到第二端的壁面上设置有沿周向的导流筋131。加热腔22类似为圆筒形，导流筋131沿着圆周方向设置。具体的，导流筋131可以有多个，在加热腔22的轴向，即从第一端到第二端，间隔排列。通过导流筋131的设置，能够对加热腔22中的流体起到导流作用，增加流体在加热腔22中的旋绕程度。在一些实施例中，导流筋131也可以是连续的螺旋形，从该加热腔22的第 一端向第二端看，导流筋131沿顺时针方向旋转延伸，即，导流筋131的旋转方向与流体在加热腔22中的旋转方向一致，能够进一步增强水流的旋绕效果，从而实现对流体的均匀加热，避免干烧。
在一些实施例中，如图22和图24所示，加热泵100还包括端盖5，端盖5包括进水端盖52和出水端盖53。
在一些实施例中，如图22所示，进水端盖52插入泵腔21内并与泵壳2贴合，即，进水端盖52的外壁与泵腔21的内壁之间不存在间隙。具体的，进水端盖52可以通过多种固定方式与泵壳2固定，例如，粘接，焊接等多种。
在一些实施例中，如图22和图24所示，进水端盖52依次包括引入流体的进水通道54、流道横截面面积减小的整流通道55和与叶轮3外侧形成间隙的配合通道56。其中，进水端盖52用于与加热泵100外部的外部管道连接，流体由外部管道流入进口连接段211的进水通道54，并沿进水通道54流入整流通道55。在整流通道55中，流体被整流，湍流度降低，并流入配合通道56中。液体由配合通道56的进入叶轮3，经过叶轮3离心从径向流出，然后流入泵腔的水泵蜗壳212。配合通道56与叶轮3的外侧形成间隙，与叶轮3匹配形成狭小通道，抑制流体经过叶轮3后的回流量，从而提高加热泵100的效率。
在一些实施例中，进水端盖52可以是轴对称结构，进水端盖52、泵腔21以及叶轮3同轴设置，从而能够使水流均匀、对称地在进水端盖52和叶轮3中流动。
加热件4固定于加热腔22的第一端，端盖5(例如出水端盖53)固定于加热腔22的第二端，以封盖加热腔22的第二端。在安装加热泵100时，将加热件4由加热腔22的第二端伸入加热腔22中，并将加热件4固定于加热腔22的第一端，在加热件4安装完成后，将端盖5与泵壳2连接，以封盖加热腔22的第二端。端盖5可以通过多种方式固定于加热腔22的第二端，在一些实施例中，端盖5通过不可拆卸的方式与加热腔22的第二端连接，例如，端盖5通过焊接固定于加热腔22的第二端，通过不可拆卸的方式连接端盖5与加热腔22的第二端，能够在不设置密封元件的前提下保证端盖5与加热腔22的第二端之间的密封性；在另一些实施例中，端盖5可拆卸地固定于加热腔22的第二端，例如，端盖5通过螺钉与加热腔22的第二端连接，并在端盖5与加热腔22的第二端之间设置密封垫圈，防止加热腔22中的流体由端盖5与加热腔22的第二端之间的接缝处漏出，通过可拆卸的方式将端盖5固定于加热腔22的第二端，可以在加热件4故障时拆下端盖5，并对加热件4进行更换或维修，而无需在加热件4损坏时报废整个加热泵100。
在一些实施例中，如图24所示，进水端盖52与出水端盖53固定连为一体，能够 在安装进水端盖52的同时将出水端盖53固定于加热腔22的第二端，简化了加热泵100的安装。在另一些实施例中，进水端盖52与出水端盖53为分离的两个部件，在安装时，进水端盖52与出水端盖53之间不会发生干涉，降低了对进水端盖52与出水端盖53的加工精度的要求。
本申请实施例还提供一种清洁装置。所述清洁装置包括如前述实施例所述的加热泵100，清洁装置具有清洁物品的清洁空间，该清洁空间的入水口与加热泵100的出水口24连通。
在一些实施例中，该清洁装置例如可以是洗碗机，将碗置入清洁空间中，加热泵100将加热后的带有洗洁精的热水注入清洁空间中，以对碗进行洗涤，然后加热泵100将加热后的清水注入清洁空间中，以对碗进行漂洗，冲走碗上的泡沫，实现清洁碗的目的。
