需要说明，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，全文中出现的“和/或”的含义为，包括三个并列的方案，以“A和/或B”为例，包括A方案，或B方案，或A和B同时满足的方案。
本申请提出一种泵盖，应用于离心泵等需要实现加热功能的加热泵。
在本申请实施例中，如图1至图5所示，该泵盖100包括盖体110及加热器120；盖体110具有相对的外壁面111和内壁面112，内壁面112适用于与流体介质接触，内壁面112上形成有凸部1121。加热器120包括加热部121，加热部121位于盖体110的内壁面112所在的一侧，且与凸部1121相连接。
在本实施例中，盖体110可以仅包括平板状的盖板。此时，盖体110的外壁面111和内壁面112也即盖板两相对的板面。盖体110也可以包括盖板和由盖板的周缘向一侧延伸的裙边。此时盖体110的内壁面112指的是盖板位于裙边一侧的板面，外壁面111指的是盖板的另一侧板面。该流体介质通常为水，在一些实施例中，流体介质也可以为油或其他液体。当泵盖100安装至泵体200中使用时，盖体110的内壁面112朝向泵体200的泵腔，则使得泵腔中的流体介质可与盖体110的内壁面112相接触。而通过盖体110盖合泵体200的敞口，则使得盖体110的外壁面111不会与泵腔内的流体介质接触。盖体110与加热部121的材质均采用导热材质，例如可以为钢等。
可以理解的是，内壁面112上形成有凸部1121，则该凸部1121与盖体110可以一体成型设置，则凸部1121可以为凸出盖体110的内壁面112设置的实心结构，此时凸部1121与盖体110一体注塑成型。该凸部1121也可以为盖体110的外壁面111向内壁面112一侧隆起而形成，此时该凸部1121在盖体110的外壁面111一侧相当于凹设的凹槽，则该凸部1121可以由盖体110的外壁面111一侧向内壁面112一侧冲压而成。凸部1121与盖体110也可以分体成型设置，则凸部1121可以通过焊接等方式固定于盖体110的内壁面112上。此时，该凸部1121的材料应与盖体110的材料相一致，以保证整体的热传导性能。凸部1121的纵截面形状可以为半圆形、半椭圆形等各种弧状结构，也可以为矩形、三角形等各种多边形，在此不做具体限定。该凸部1121可以包括凸点、凸块、凸条中的一种或多种。且在凸部1121包括凸点或凸块时，通常使得凸点或凸块为多个，且沿加热部121的延伸方向间隔设置。可以理解的是，凸部1121朝向加热部121的表面均与加热部121贴合，也即整个凸部1121均与加热部121贴合。
加热器120通常包括加热部121和连接于加热部121的两个引出部122，两个引出部122并排延伸，加热部121的两端分别与两个引出部122连接。加热部121设置在盖体110的内壁面112所在一侧，以用于对流体介质进行加热，引出部122与设置在盖体110的外壁面111所在一侧的绝缘插座电连接。引出部122具体穿设盖体110设置，以与该绝缘插座电连接，且引出部122与盖体110的连接处通过密封结构密封，以防止流体介质溢出。加热部121具体可包括盘管段，盘管段在两个引出部122之间弯曲延伸。盘管段具体可以仅蜿蜒一圈，也可以蜿蜒两圈或两圈以上，可根据实际需求进行选择和设计。需要说明的是，加热部121与凸部1121相连接，则可以仅使得加热部121与凸部1121相互抵接，此时，使得加热器120的引出部122与盖体110焊接或过盈配合连接，以将加热器120固定于盖体110上。当然，加热部121与凸部1121也可以通过焊接、胶水粘接等。
本申请泵盖100通过使得盖体110具有相对的外壁面111和内壁面112，内壁面112适用于与流体介质接触，内壁面112上形成有凸部1121；加热器120包括加热部121，加热部121位于盖体110的内壁面112所在的一侧，且与凸部1121相连接。使得加热器120可以伸入泵体200的泵腔内与待加热的流体介质直接接触，热量损失小，加热效率高。加热部121与盖体110连接，相比于加热部121不与盖体110接触的方式，可使得加热器120的热量传递给盖体110，则可将安全装置130（例如温度保险丝）放置在盖体110的外壁面111，相比于在加热器120的引出部122内设置安全装置130，使安全装置130的传热路径更短，熔断时间更短，对加热器120的异常感应灵敏。同时加热部121与盖体110内壁面112上的凸部1121相连接，相比于将加热部121与盖体110的内壁面112直接连接，可减小连接难度。且能够增大加热部121与盖体110板面的间隙，结合凸部1121的作用，可减小加热部121与盖体110间的流体阻力，提升加热部121与盖体110间的液体流通率，进而增大加热器120的加热效率。
在一实施例中，所述凸部1121与所述加热部121的接触面积与所述加热部121的外表面面积的比值小于或等于0.3。
具体的，凸部1121与加热部121的接触面积与加热部121的外表面的比值可以为0.01、0.05、0.1、0.13、0.15、0.18、0.2、0.25、0.28、0.3等。可选地，凸部1121与加热部121的接触面积与加热部121的外表面面积的比值小于或等于0.1。通过使得凸部1121与所述加热部121的接触面积与所述加热部121的外表面面积的比值小于或等于0.3，则有效减小加热部121与凸部1121的接触面积，使得加热部121的绝大部分外表面均能够与液体进行热交换，从而有效提升整体换热效率。可以理解的是，当凸部1121与所述加热部121的接触面积与所述加热部121的外表面的比值足够小时，使得加热部121与凸部1121接近于或实质为点接触或线接触，则可使得凸部1121与加热部121的接触面积达到最小，使得加热部121的外表面几乎都能够用来与液体接触，从而最大化加热部121的热交换面积，极大地提升了整体的换热效率。
在一实施例中，所述凸部1121的横截面所在外轮廓尺寸自内壁面112向所述加热部121逐渐减小，和/或，所述加热部121的横截面所在外轮廓尺寸自其轴线向所述凸部1121逐渐减小。
在本实施例中，凸部1121的横截面指的是用平行盖体110板面的平面切合凸部1121所得到的面。同理，加热部121的横截面指的是用平行盖体110板面的平面切合加热部121所得到的面。则凸部1121可以呈弧形凸部1121、锥形凸部1121或其他横截面所在外轮廓尺寸自内壁面112向加热部121逐渐减小的形状。加热部121朝向凸部1121的部分可以呈弧形、锥形或其他横截面所在外轮廓尺寸自加热部121的轴线向凸部1121逐渐减小的形状。需要说明的是，当加热部121为非对称结构时，加热部121的轴线指的是其纵截面上的中分线。通过使得所述凸部1121的横截面所在外轮廓尺寸自内壁面112向所述加热部121逐渐减小，和/或，所述加热部121的横截面所在外轮廓尺寸自其轴线向所述凸部1121逐渐减小，则使得凸部1121与加热部121的接触面积更小，从而能够增大加热部121与液体的换热面积，提高加热效率。
进一步地，请参照图2至图5，凸部1121朝向加热部121的表面，以及加热部121朝向凸部1121的表面的至少一者呈弧面设置。
在本实施例中，使得凸部1121朝向加热部121的表面，以及加热部121朝向凸部1121的表面的至少一者呈弧面设置，则存在三种情况。第一种情况，凸部1121具有第一弧面112a，加热部121具有第二弧面1211，第一弧面112a与第二弧面1211相连接。可以理解的是，该第一弧面112a朝向加热部121设置，则该第一弧面112a可以仅为凸部1121的部分表面，也可以为凸部1121的整个表面，也即整个凸部1121的表面呈弧形设置。该第二弧面1211朝向凸部1121设置，该第二弧面1211可以仅为加热部121的部分表面，也可以为加热部121的整个表面，也即整个加热部121的横截面呈圆形或椭圆形设置。通过使得凸部1121的第一弧面112a与加热部121的第二弧面1211相连接，则使得凸部1121与加热部121为线接触，可进一步减小凸部1121与加热部121的接触面积，使得加热器120大部分面积可与液体进行热交换，提高了加热效率。且在凸部1121与加热部121通过焊接连接时，便于焊料的填充，且使得焊料分布更为均匀，进而减小加热部121与盖体110的焊接难度，提升产品制造可行性。可选地，凸部1121的表面及加热部121的表面均呈弧面设置。则可进一步减小流体阻力，提升液体流通率，进而增大加热器120的加热效率。
第二种情况，凸部1121具有第一弧面112a，加热部121与第一弧面112a相连接。此时加热部121朝向凸部1121的表面为非弧面，则加热部121朝向凸部1121的表面为平面。则仅通过使得凸部1121的第一弧面112a与加热部121相连接，凸部1121与加热部121为线接触，同样可以实现减小凸部1121与加热部121的接触面积，使得加热器120大部分面积可与液体进行热交换，以提高整体的加热效率。第三种情况，加热部121具有第二弧面1211，第二弧面1211与凸部1121相连接。此时凸部1121朝向加热部121的表面为非弧面，则凸部1121朝向加热部121的表面为平面。则仅通过使得加热部121的第二弧面1211与凸部1121相连接，使得凸部1121与加热部121为线接触，同样可以实现减小凸部1121与加热部121的接触面积，使得加热器120大部分面积可与液体进行热交换，以提高整体的加热效率。使得凸部1121朝向加热部121的表面，以及加热部121朝向凸部1121的表面的至少一者呈弧面设置，则凸部1121和加热部121从工艺上更好实现，便于成型制造。
在一实施例中，如图2至图4所示，加热部121包括盘管段，凸部1121沿盘管段的延伸方向延伸。
在本实施例中，具体地，该盘管段的盘管位于同一平面上。也即盘管段整体呈C型延伸，只弯曲一圈，则使得盘管段对流体的阻碍小，结合盘管段与凸部1121相连接的方式，使得加热部121的热量也能够传递至盖体110，则盖体110可实现对流体的加热，继而在减小流体阻力的同时增大了整体的换热面积，以提升整体的加热效果。使得凸部1121呈条状设置，且沿盘管段的延伸方向延伸，则使得凸部1121与盘管段呈仿形设置。如此，使得整个盘管段在其延伸方向上均能够与凸部1121连接，从而可提升两者的连接稳固性，且使得加热部121的热量能够快速传递至盖体110上，进而使得安装在盖体110的外壁面111上的安全装置130的感应更为灵敏，对整机的安全保护效果更佳。同时，使得安全装置130的位置可根据实际需求灵活布置。可选地，加热器120还包括连接段，连接段呈弧形设置，连接段连接盘管段和引出部122。
在另一实施例中，加热部121包括盘管段，凸部1121包括多个凸起，多个凸起绕盖体110的周向间隔设置，盘管段与多个凸起均连接。该凸起可以为凸点、凸块或凸条。相邻两凸起之间的间距可以相同，也可以不同。凸起的数量也可以为两个、三个、四个、五个等，具体可根据实际需求选择凸起的数量和布局位置。使得盘管段与多个凸起均连接，则可提升盘管段与盖体110的连接稳固性，且使得安全装置130的位置可根据实际需求灵活布置。同时，由于盘管段部分不与凸起接触，则可使得盘管段未与凸起接触的部分均能够给液体环绕，进而可进一步增大加热器120的热交换面积，提升整体的加热效率。
实际而言，加热部121与凸部1121焊接。加热部121与凸部1121可以采用镍基焊接或钎焊，可根据实际需求选择合适的导热焊料。使得加热部121与凸部1121焊接，则可保证凸部1121与加热部121紧密贴合，则一方面可提升两者的连接稳定性，另一方面可保证加热部121的热量能够通过凸部1121快速传递至盖体110上，进而便于安装在盖体110的外壁面111的安全装置130进行快速反应动作。
进一步地，凸部1121由盖体110的外壁面111朝向盖体110的内壁面112隆起形成。通过使得凸部1121由盖体110的外壁面111朝向盖体110的内壁面112隆起形成，也即从盖体110的外壁面111一侧观测而言，盖体110的外壁面111向下凹陷而形成该凸部1121，则使得该凸部1121可由盖体110的外壁面111一侧向内壁面112一侧冲压形成，从而有利于凸部1121的加工和制造。且相比于使得凸部1121与盖体110分体成型，通过焊接等工艺将凸部1121连接于盖体110的内壁面112的方式而言，可减少加工步骤，提升凸部1121与盖体110的连接稳固性。此外，相比于使得凸部1121为实心结构而言，可避免热量集中在凸部1121，更加有利于将加热部121的热量均匀传递至盖体110上。
在一实施例中，如图2至图4，图8及图9所示，凸部1121具有浅端112b和深端112c，浅端112b的凸出高度小于深端112c的凸出高度；
泵盖100还包括安全装置130，安全装置130与加热器120连接，安全装置130被配置为在达到第一预设温度后切断加热器120的供电，安全装置130安装于外壁面111，且对应浅端112b设置。
在本实施例中，绝缘插座包括安全装置130，安全装置130优选为不能复位的结构。该安全装置130与电源连接，则当加热部121通过凸部1121传递给安全装置130的温度达到或超过第一预设温度后，安全装置130熔断，则能够断开加热器120的供电电路，进而保证整个加热泵的安全。安全装置130具体可以为温度保险丝或其他熔断器。可以理解的是，凸部1121的凸出高度指的是，凸部1121凸出盖体110的内壁面112的高度。通过使得浅端112b的凸出高度小于深度的凸出高度，也即使得凸部1121具有高度变化的截面。安全装置130可以通过焊接、卡接等方式固定在盖体110的外壁面111上。安全装置130对应凸部1121的浅端112b设置，则安全装置130至少部分覆盖盖体110的外壁面111对应凸部1121的浅端112b的位置。通过使得安全装置130对应凸部1121的浅端112b设置，则相较于将安全装置130对应凸部1121的深端112c设置，由于凸部1121的凸部1121高度较小，则使得加热部121到安全装置130之间的传热路径更短，从而安全装置130对加热器120的异常感应灵敏，则可提升产品质量。通过使得安全装置130设置在盖体110的外壁面111上，且使得加热部121通过凸部1121与盖体110连接，相比于将安全装置130设置在加热器120内，使得加热管的热量能够快速且低耗散的传递至安全装置130，从而安全装置130对加热部121的温度更为敏感，使得整体的安全性和可靠性更高。此外，还可以在加热器120中设置安全装置130，以实现双层保险。
进一步地，如图2至图4所示，凸部1121的凸出高度自浅端112b向深端112c逐渐增大设置。使得凸部1121的凸出高度自浅端112b向深端112c逐渐增大设置，则凸部1121截面的高度按一定规律持续变化，则可减小凸部1121的应力和温度集中，使得加热部121传递至凸部1121的温度分布更为均匀，则使得整个加热系统更为稳定。结合凸部1121呈条状设置的实施例，则整个条状凸部1121的凸出高度连续变化。结合凸部1121包括多个间隔设置的凸起的实施例，则凸部1121的深端112c可以为整个凸部1121一端的凸起，凸部1121的浅端112b为整个凸部1121另一端的凸起。则单个凸起的高度可以呈变化设置，也可以一致。只需使得多个凸起的凸出高度整体自浅端112b向深端112c逐渐增大即可。在其他实施例中，凸部1121的凸出高度自浅端112b向深端112c也可以呈不均匀增大设置。
在一实施例中，请参照图4，泵盖100还包括温度控制装置140，温度控制装置140与加热器120及安全装置130电连接，温度控制装置140被配置为在达到第二预设温度后切断加热器120的供电，第二预设温度小于第一预设温度，温度控制装置140安装于外壁面111，且与凸部1121相对设置。
在本实施例中，绝缘插座包括温度控制装置140。温度控制装置140为可恢复的结构，也即温度控制器能够实现断开和导通与加热器120的电路连接。温度控制装置140与电源和安全装置130均电连接。温度控制装置140可以通过焊接、卡接等方式固定在盖体110的外壁面111上。温度控制装置140安装在盖体110的外壁面111，则能够感应到液体的温度，进而当温度大于第二预设温度时，可切断加热器120的供电，电加热器120停止工作。当液体温度降低到设定的温度时，温度控制装置140又会打开，接通电路，使得电加热器120工作，实现加热泵腔中的液体。而通过使得温度控制装置140对应凸部1121设置，则温度控制装置140能够直接监控加热部120的温度，从而温度控制装置140对液体沸腾导致加热部120局部过热产生的异常感应灵敏，进而提升产品的可靠性，保证产品质量。温度控制装置140与凸部1121相对设置，则温度控制装置140至少部分覆盖盖体110的外壁面111正对凸部1121的位置。当温度控制装置140失效时，加热器120温度持续升高，则当达到第一预设温度时，安全装置130熔断，使得整个装置的线路被切断，并不可恢复。
具体而言，如图1、图2、图6至图9所示，加热器120还包括与加热部121连接的引出部122，引出部122穿设盖体110设置，以至少部分位于盖体110的外壁面111所在一侧，深端112c邻近引出部122设置，浅端112b远离引出部122设置。
在本实施例中，引出部122设置有两个，使得其中一个引出部122与温度控制装置140电连接，另一个引出部122与安全装置130电连接，以实现对整个加热器120的控制。可以理解的是，引出部122与盖体110的连接处密封设置，以防止液体溢出。加热器120通过引出部122与安全装置130和温度控制装置140电连接，可保证整个系统的安全性和可靠性。使得深端112c邻近引出部122设置，浅端112b远离引出部122设置，则安全装置130设置在远离引出部122的位置，使得盖体110上的结构布局更为合理。当凸部1121呈C型条状时，引出部122设置在盖体110上对应C型凸部1121的开口的位置，以引出部122为参考，此时深端112c为C型凸部1121的近端，浅端112b为C型凸部1121的远端。
在一实施例中，请参照图6及图7，加热部121与引出部122呈锐角设置，加热部121远离引出部122的末端与凸部1121的浅端112b相连接。加热部121具体包括盘管段，盘管段呈弧形延伸，引出部122为竖直延伸的管状结构。加热部121与引出部122呈锐角设置，也即使得加热部121所在的平面与引出部122所在的平面呈锐角设置（如图7中的角α）。可选地，加热部121与引出部122之间的夹角大于或等于70度，且小于或等于88度。则该加热与引出部122之间的夹角具体可以为75度、80度、85度、87度、88度等。通过使得加热部121与引出部122呈锐角设置，结合凸部1121具有深端112c和浅端112b，深端112c邻近引出部122设置，浅端112b远离引出部122设置，使得整个加热部121的倾斜方向与凸部1121的倾斜方向保持一致，则使得加热部121与凸部1121的连接更为方便，同时使得引出部122能够垂直向盖体110的外壁面111一侧延伸，进而保证整个泵盖100的安装和连接可靠性。使得加热部121远离引出部122的末端与凸部1121的浅端112b相连接，也即凸部1121的浅端112b位于最远离引出部122的位置，则使得安全装置130也对应设置在最远离引出部122的位置，从而使得整个盖体110上的重力分布均匀，结构布局更为合理。
本申请还提出一种加热泵，如图8及图9所示，该加热泵包括泵体200和泵盖100，该泵盖100的具体结构参照上述实施例，泵盖100安装于泵体200，由于本加热泵采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
该泵盖100具体可以通过密封圈等密封结构密封安装在泵体200上。当然，泵盖100还通过螺钉、螺栓、铆接等方式与泵体200固定连接。加热泵还包括安装于泵体200内的叶轮以及与该泵体200组合并驱动叶轮旋转的电机。则通过电机驱动叶轮转动，以驱动水流由进水口进入泵体200内，经由加热器120加热后由出水口流出，以实现水流的加热和泵送。
本申请还提出一种家用电器，该家用电器包括加热泵，该加热泵的具体结构参照上述实施例，由于本家用电器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。在一实施例中，该家用电器为洗碗机。当然，在其他实施例中，该家用电器也可以为洗衣机或其他需要加热泵的电器，在此不做具体限定。
