具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的其他方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图14描述根据本申请一些实施例的进出水装置、电器和热水器。
如图1、图2和图4所示,本申请第一方面的实施例提供了一种进出水装置,进出水装置包括流通部件100,流通部件100内部形成有第一绝缘流道106和第二绝缘流道107,流通部件100具有第一进水口101和第一出水口103, 第一绝缘流道106导通第一进水口101和第一出水口103,流通部件100具有第二进水口102和第二出水口104,第二绝缘流道107导通第二进水口102和第二出水口104。
本申请上述实施例提供的进出水装置,设置流通部件100内形成有第一绝缘流道106和第二绝缘流道107,这样,增加了流通部件100的功能,例如,设置第一绝缘流道106进水,第二绝缘流道107出水,使得流通部件100同时具有进水及出水的功能,或者,设置第一绝缘流道106供冷水流通,第二绝缘流道107供热水流通,使得流通部件100同时具有供冷水及热水的功能,且较现有的利用多个单通道管子实现多流道的方案而言,本方案一个流通部件100即具有两个流道,减少了管子的数量,在安装过程中,减少安装步骤,缩短了装配时间,降低了成本,且由于减少了管子的数量,进而减少了供进出水装置安装的安装孔的数量,降低了漏水隐患,此外,两个流道为绝缘流道,降低漏电的风险,提升产品的使用安全。
实施例1:
除上述实施例的特征以外,本实施例进一步限定了:第一绝缘流道106包括多个子流通段,多个子流通段之间连通,且多个子流通段形成折流分布。设置多个子流通段之间连通并形成折流分布,使得第一绝缘流道106的长度增加,利用水的等效电阻特性(水电阻衰减隔离法),进一步增强第一绝缘流道106的防电性,避免漏电风险,提升产品的使用安全。
举例地,多个子流通段并排分布且相邻子流通段之间首尾相连,形成类似蛇形或波浪形或折线形的折流。
当然,本方案并不局限于此,在其他实施例中,也可以设计多个子流通段呈迂回分布,具体地,如图4所示,流通部件100包括第一管体110及第二管体120,其中,第二管体120套装于第一管体110外,且第二管体120的内壁与第一管体110的外壁之间形成有缝隙130,在第一管体110内设有隔板180A,隔板180A将第一管体110分隔成第一通道111及第二通道112,其中第一通道111与缝隙130连通,第一通道111与缝隙130形成为第一绝缘流道106,多个子流通段包括第一通道111及缝隙130,其中,第一进水口101设于第一管体110上,第一出水口103设于第二管体120上,且第一进水口101与第一 出水口103位于同一侧,第一通道111与缝隙130连通处位于另一侧,这样,水沿第一进水口101进入第一通道111,并在第一通道111与缝隙130连通处进入缝隙130,最后沿第一出水口103流出,水在第一通道111的流动方向与在缝隙130中的流动方向相反,从而形成迂回的流动路径,在增加第一绝缘流道106的长度的同时,部件之间更加紧凑,减小产品的体积,有利于产品的小型化。进一步地,第二管体120的内壁与第一管体110的外壁之间间隔分布,使得第二管体120的内壁与第一管体110的外壁之间形成有呈环形的缝隙130,第一通道111被缝隙130包围,使得缝隙130可以环向出水,增加出水的速度及均匀性。
进一步地,第二绝缘流道107与多个子流通段间壁设置。这样,一方面使得第二绝缘流道107与多个子流道之间互不干扰,保证第一绝缘流道106与第二绝缘流道107之间的相互独立性,另一方面,第二绝缘流道107与多个子流通段之间的间壁设计,有利于降低第二绝缘流道107与多个子流通之间的热传递效率,减少热量损失。
实施例2:
除上述实施例的特征以外,本实施例进一步限定了:流通部件100包括第一管体110及第二管体120,第二管体120套装于第一管体110外,第二管体120内与第一管体110外之间形成有缝隙130,第一管体110内具有第一通道111及第二通道112,第二通道112形成第二绝缘流道107,第一通道111与缝隙130导通且形成第一绝缘流道106。
举例地,第二管体120套装于第一管体110外,且第二管体120的内壁与第一管体110的外壁之间形成有缝隙130,在第一管体110内设有隔板180A,隔板180A将第一管体110分隔成第一通道111及第二通道112,其中第一通道111与缝隙130连通,在第一管体110的壁上设有通孔113,使得第一通道111与缝隙130连通,当然,本方案并不局限于此,在其他实施例中,也可以设计第一通道111与缝隙130之间通过导管等导通结构连通,在此不再一一列举,但在不脱离本设计构思的前提下均属于本方案的保护范围。第一通道111与缝隙130形成为第一绝缘流道106,第二通道112形成为第二绝缘流道107。
第二管体120套装于第一管体110外,使得第一管体110与第二管体120 形成一个整体的管子,这样,在安装过程中,第一管体110与第二管体120可以一同安装到位,减少安装步骤,缩短了装配时间,降低了成本,且由于第一管体110与第二管体120形成一个整体的管子,仅需一个安装孔即可实现第一管体110与第二管体120的安装,减少了安装孔的数量,降低了漏水隐患,同时,设置第一通道111与缝隙130导通且形成第一绝缘流道106,第二通道112形成第二绝缘流道107,这样,两个管体之间结构简单,且第一绝缘流道106和第二绝缘流道107的阻力小,有利于提升水在流道内流通的顺畅性,提升水流速度,提高进水及出水的效率。
进一步地,第一通道111内设有封堵件140,第一进水口101位于封堵件140的一侧,第一通道111位于封堵件140与第一进水口101之间的部位与缝隙130连通。
举例地,第一管体110具有相对的第一孔及第二孔,其中第一孔形成为第一进水口101,封堵件140(例如橡胶塞)设于第一通道111内且位于第二孔和第一通道111与缝隙130连通处之间,详细地,在第一管体110的壁上设有通孔113,使得第一通道111与缝隙130连通,封堵件140设于第一通道111内且位于第二孔和通孔113之间,使得第一进水口101与缝隙130经通孔113连通,且第一进水口101与第二孔被阻挡,这样,水沿第一进水口101进入第一通道111,在经通孔113流入缝隙130并沿第一出水口103排出,水在第一通道111的流动方向与在缝隙130中的流动方向相反,从而形成迂回的流动路径,使得第一绝缘流道106的长度增加,利用水的等效电阻特性,进一步增强第一绝缘流道106的防电性,避免漏电风险,提升产品的使用安全。
实施例3:
如图3和图4所示,除上述任一实施例的特征以外,本实施例进一步限定了:第二管体120的一端设有开口121,开口121与缝隙130连通,其中,开口121作为第一出水口103,这样有利于充分利用缝隙130,进一步延长第一绝缘流道106的长度,进一步增强第一绝缘流道106的防电性,避免漏电风险,提升产品的使用安全。
在另一个实施例中,第二管体120的侧壁上邻近开口121的一端凹陷形成有凹口,凹口作为第一出水口103。
或者,第二管体120设有多个凸起,多个凸起沿开口121的边缘间隔的分布,相邻凸起之间限定出排水口,排水口作为第一出水口103。
或者,第二管体120的侧壁上设有一个或多个排水孔123,一个或多个排水孔123作为第一出水口103。
当然,上述形式也可以任意组合。
实施例4:
如图4所示,除上述任一实施例的特征以外,本实施例进一步限定了:沿第一管体110的延伸方向,第一管体110具有相对的第一侧及第二侧,其中,第一出水口103位于第一侧,第二进水口102位于第二侧。也可以理解为,第一出水口103和第二进水口102位于第一管体110上相对的两侧,使得第一出水口103和第二进水口102之间具有一定的距离,避免水在第一绝缘流道106内沿第一出水口103排出后,立即沿第二进水口102进入第二绝缘流道107,降低第一绝缘流道106和第二绝缘流道107之间蹿流风险,举例地,设计第一绝缘流道106供冷水流入,第二绝缘流道107供热水流出,通过增加第一出水口103和第二进水口102之间的距离,避免冷水未经加热即沿第二进水口102进入第二绝缘流道107,保证热水的温度,且通过冷水在一侧流入,热水在另一侧流出,有利于减少冷热中和的消耗,进一步保证热水的温度。
实施例5:
如图1和图3所示,除上述任一实施例的特征以外,本实施例进一步限定了:第一管体110的一部分位于第二管体120内,另一部分位于第二管体120外,且第一管体110在第二管体120外的部分设有第二进水口102。也即第一管体110的长度较第二管体120的长度长,第二绝缘流道107形成于第一管体110的第二通道112,这样有利于增加第二绝缘流道107的长度,进而利用水的等效电阻特性,进一步增强第二绝缘流道107的防电性,避免漏电风险,提升产品的使用安全。
实施例6:
如图4所示,除上述任一实施例的特征以外,本实施例进一步限定了:进出水装置还具有限位件150,限位件150与第一管体110的外壁及第二管体120的内壁抵靠。通过限位件150实现第一管体110与第二管体120的连接及锁定, 结构更简单,安装更方便。
举例地,第二管体120套装于第一管体110外,第二管体120的内壁与第一管体110的外壁之间间隔分布,使得第二管体120的内壁与第一管体110的外壁之间形成有呈环形的缝隙130,限位件150呈环状,限位件150套装与第一管体110外,且第二管体120的内壁抵靠限位件150,进一步地,限位件150设有凸起结构151,第二管体120的一个端口与凸起结构151抵靠,以防止第二管体120上下移位。
如图5所示,更进一步地,在限位件150与第一管体110之间和/或限位件150与第二管体120之间设有密封件190,以密封限位件150与第一管体110之间的缝隙130和/或密封限位件150与第二管体120之间的缝隙130。
实施例7:
除上述任一实施例的特征以外,本实施例进一步限定了:第一管体110为三型聚丙烯管(PPR管)。三型聚丙烯管具有环保、轻质高强、耐腐蚀、内壁光滑不结垢、使用寿命长的优点。
第二管体120为第一管套,管套为设有管体外以防管体内的水流与管外产生热交换的绝缘材料,第二管体120为第一管套,这样,第二管体120具有一定的绝缘特性,进一步增加产品的防电效果。
当然,在其他实施例中,也可以设计第二管体120外套装有第一管套。
第一管体110的一部分位于第二管体120内,另一部分位于第二管体120外,且第一管体110在第二管体120外的部分套装有第二管套160。这样,第一管体110在第二管体120外的部分具有一定的绝缘特性,进一步增加产品的防电效果。
进一步地,第一管体110在第二管体120外的部分和第二管套160通过固定销、螺钉胶粘等方式连接。
实施例8:
如图4所示,除上述任一实施例的特征以外,本实施例进一步限定了:进出水装置具有接头170,接头170内具有两个通道171,第一绝缘流道106和第二绝缘流道107与两个通道171一一对应连通。
举例地,接头170为三型聚丙烯接头170(PPR接头170),接头170内设 有隔板180B,隔板180B将接头170内分隔为两个通道171,接头170的一端与第一管体110的一端对应连接,且接头170的隔板180B与第一管体110的隔板180A对应连接,例如,接头170与第一管体110热熔连接,使得两个通道171中的一个与第一绝缘流道106对应连通,另一个与第二绝缘流道107对应连通,接头170的另一端适于连接进水管路及出水管路,例如,在接头170的另一端,与第一绝缘流道106连通的通道171连接冷水管路,以供冷水流入,与第二绝缘流道107连通的通道171连接热水管路(例如水龙头),以实现热水的流出,也即通过一个管子实现冷水进、热水出。

本申请上述实施例提供的电器,通过设置有上述任一实施例中的进出水装置,从而具有以上全部有益效果,在此不再赘述。
具体地,电器包括热水器、壁挂炉等等,在此不再一一列举,但在不脱离本设计构思的前提下均属于本方案的保护范围。

具体地,第一管与接头170热熔连接,第一管具有第一通道111及第二通道112,第一管套套装与第一管外,且在第一管套与第一管之间设有限位环,限位环上套有O型密封圈,利用限位环实现第一管套与第一管之间同心分布, 以及第一管套与第一管之间在端部的密封,第一管套的内壁与第一管的外壁之间形成有缝隙130,第一通道111与缝隙130连通,第一通道111与缝隙130形成为第一绝缘流道106,第二通道112形成为第二绝缘流道107,第一管套下方有阵列出水口,其中,第一绝缘流道106供冷水流入,第二绝缘流道107供热水流出,第一绝缘流道106的水流方向可以参考图4中的x1,第二绝缘流道107的水流方向可以参考图4中的x2,第一绝缘流道106沿第一管套绕流,从第一管套下方出水口流出,第二绝缘流道107可控制水位高度,并使水从上方直接沿第二绝缘流道107流出,如此进水从底部流出,出水从上方流出。
进一步地,第一管的部分位于第一管套外,第一管位于第一管套外的部分套设有第二管套160,并通过固定销对第二管套160进行固定。
接头170底部设有密封槽,密封槽内安装进出水密封垫,以实现接头170的密封,进出水装置插入热水器的内胆中,接头170适于与管路接头连接,例如,接头170连接冷水管道及热水接头,冷水经接头170及第一绝缘流道106进入热水器的内胆中,经加热处理后,热水经第一绝缘流道106及热水接头流出,即既实现冷水进、热水出。
本申请第三方面的实施例提供的热水器10,如图6、图7和图9所示,包括内胆11、进水接口1210和出水接口122、管体1300。
具体地,内胆11具有容纳空间1110,管体1300与内胆11连接,管体1300内具有第一绝缘流道1301和第二绝缘流道1302,第一绝缘流道1301连通进水接口1210和容纳空间1110,第二绝缘流道1302连通出水接口122和容纳空间1110。

实施例9:
如图8和图9所示,除上述实施例的特征以外,本实施例进一步限定了:内胆11设有插接部1120,插接部1120与管体1300插接配合。这样,管体1300与内胆11之间的连接更简单,组装方便,有利于缩短装配时间,且利用插接部1120与管体1300插接配合,实现内胆11与管体1300之间的对准,从而促进内胆11与管体1300之间的组装精度和组装牢靠性。
进一步地,如图10所示,插接部1120包括安装槽1121,安装槽1121与容纳空间1110连通,管体1300的部分伸入安装槽1121内,管体1300的另一部分沿安装槽1121伸入于容纳空间1110。这样,插接部1120结构简单,加工方便,且管体1300的部分伸入安装槽1121内,增加了管体1300与安装槽1121之间的连接面积,进而使得管体1300与安装槽1121之间的连接更稳定,有效的防止管体1300与安装槽1121松脱,提高管体1300与安装槽1121的连接可靠性,且管体1300与安装槽1121之间的连接面积增加,有利于降低管体1300与内胆11之间漏水的风险,提升产品的可靠性及安全性。
举例地,在内胆11的外壁上设有凸出于内胆11外壁的安装槽1121,管体1300插入安装槽1121内并经安装槽1121伸入于容纳空间1110,其中,管体1300的外壁与安装槽1121的内壁之间设有密封件密封管体1300的外壁与安装槽1121的内壁之间的缝隙133,以防止漏水。
更进一步地,如图10所示,安装槽1121包括台阶槽,台阶槽包括第一槽及第二槽,第一槽和第二槽过渡衔接,管体1300具有插接配合部及限位部,其中,插接配合部伸入于第一槽内并与第一槽插接配合,限位部伸入于第二槽内并与第二槽抵靠。这样,在插接配合部伸入于第一槽内并与第一槽插接配合以实现内胆11与管体1300之间连接的同时,第二槽对限位部形成限位,避免在安装过程中用力过度,导致管体1300穿出安装槽1121的风险,进一步提升组装便利性,且第二槽和限位部的配合有利于进一步降低漏水的风险。
更进一步地,安装槽1121和管体1300这两者中的一者设有凸筋135,凸筋135与安装槽1121和管体1300这两者中的另一者抵靠配合。通过凸筋135进一步提升管体1300与安装槽1121之间的连接可靠性,降低管体1300松脱 的风险,进而降低漏水的风险。
实施例10:
如图9、图10和图11所示,除上述任一实施例的特征以外,本实施例进一步限定了:热水器10具有分水管1400,分水管1400与内胆11连接,且分水管1400上设有进水接口1210和出水接口122。可以理解的,进水接口1210适配为连接进水管路,出水接口122适配为连接出水管路,可以理解的,进水接口1210适配为连接进水管路,出水接口122适配为连接出水管路,这样,通过一个分水管1400实现进水管路及出水管路的连接,进一步减少了产品的部件,产品结构更简洁,组装更方便,有利于进一步缩短组装时间。
进一步地,分水管1400内具有第一管道142和第二管道143,第一管道142连通进水接口1210及第一绝缘流道1301,第二管道143连通出水接口122及第二绝缘流道1302。第一管道142和第二管道143之间具有独立性,避免第一绝缘流道1301的水与第二绝缘流道1302的水在分水管1400内混合、干扰,保证分水管1400的可靠性。
更进一步地,管体1300内设有第一分隔板136,第一分隔板136将管体1300内分隔出第一子流道13401和第二子流道13402,第一子流道13401形成为第一绝缘流道1301的一部分,第二子流道13402形成为第二绝缘流道1302的一部分,分水管1400内设有第二分隔板141,第二分隔板141将分水管1400分隔出第一管道142和第二管道143,其中,分水管1400具有抵靠壁144,抵靠壁144抵靠内胆11及管体1300,且第一分隔板136对应抵靠第二分隔板141。
举例地,分水管1400内设有第二分隔板141,第二分隔板141将分水管1400内分隔为第一管道142和第二管道143,分水管1400的一端具有抵靠壁144,抵靠壁144与管体1300一端对应连接,且第一分隔板136对应抵靠第二分隔板141,使得第一管道142与第一绝缘流道1301对应连通,第二管道143与第二绝缘流道1302对应连通,分水管1400的另一端设有进水接口1210和出水接口122,进水接口1210适于连接进水管路,出水接口122适于连接出水管路,例如,进水接口1210连接冷水管路,以供冷水流入,出水接口122连接热水管路(例如水龙头),以实现热水的流出,也即通过一个分水管1400实现冷水进、热水出,分水管1400与管体1300之间通过紧固件(例如螺钉等) 锁紧,这样的连接方式较分水管1400通过螺纹连接而言,有利于第一绝缘流道1301和第一通道1311之间以及第二绝缘流道1302和第二通道1312的对准定位。
实施例11:
如图12、图13和图14所示,除上述任一实施例的特征以外,本实施例进一步限定了:管体1300包括第一管体131及第二管体132,第二管体132套装于第一管体131外,第二管体132内壁与第一管体131外壁之间形成有缝隙133,第一管体131内具有第一通道1311及第二通道1312,第一通道1311与缝隙133导通且形成第一绝缘流道1301,第二通道1312形成第二绝缘流道1302。这样,在安装过程中,第一管体131与第二管体132可以一同安装到位,减少安装步骤,缩短了装配时间,降低了成本,且由于第一管体131与第二管体132形成一个整体的管子,仅需在内胆11上设置一个安装孔即可实现第一管体131与第二管体132的安装,减少了安装孔的数量,降低了漏水隐患,同时,设置第一通道1311与缝隙133导通且形成第一绝缘流道1301,第二通道1312形成第二绝缘流道1302,这样,两个管体1300之间结构简单,且第一绝缘流道1301和第二绝缘流道1302的阻力小,有利于提升水在流道内流通的顺畅性,提升水流速度,提高进水及出水的效率。
举例地,第二管体132套装于第一管体131外,且第二管体132的内壁与第一管体131的外壁之间形成有缝隙133,在第一管体131内设有分隔结构(例如分隔板),分隔结构将第一管体131分隔成第一通道1311及第二通道1312,其中第一通道1311与缝隙133连通,在第一管体131的壁上设有通孔,使得第一通道1311与缝隙133连通,当然,本方案并不局限于此,在其他实施例中,也可以设计第一通道1311与缝隙133之间通过导管等导通结构连通,在此不再一一列举,但在不脱离本设计构思的前提下均属于本方案的保护范围。第一通道1311与缝隙133形成为第一绝缘流道1301,第二通道1312形成为第二绝缘流道1302。
进一步地,第一通道1311内设有封堵件,第一绝缘流道的进水口13011位于封堵件的一侧,第一通道1311位于封堵件与第一绝缘流道的进水口13011之间的部位与缝隙133连通。
举例地,第一管体131具有相对的第一孔及第二孔,其中第一孔形成为第一绝缘流道的进水口13011,封堵件(例如橡胶塞)设于第一通道1311内且位于第二孔和第一通道1311与缝隙133连通处之间,详细地,在第一管体131的壁上设有通孔,使得第一通道1311与缝隙133连通,封堵件设于第一通道1311内且位于第二孔和通孔之间,使得第一绝缘流道的进水口13011与缝隙133经通孔连通,且第一绝缘流道的进水口13011与第二孔被阻挡,这样,水沿第一绝缘流道的进水口13011进入第一通道1311,在经通孔流入缝隙133并沿第一绝缘流道的出水口13012排出,水在第一通道1311的流动方向与在缝隙133中的流动方向相反,从而形成迂回的流动路径,使得第一绝缘流道1301的长度增加,利用水的等效电阻特性,进一步增强第一绝缘流道1301的防电性,避免漏电风险,提升产品的使用安全。
进一步地,第一通道1311与缝隙133形成折流分布。设置第一通道1311与缝隙133形成折流分布,使得第一绝缘流道1301的长度增加,利用水的等效电阻特性,进一步增强第一绝缘流道1301的防电性,避免漏电风险,提升产品的使用安全。
举例地,第一通道1311与缝隙133之间首尾相连,形成类似蛇形或波浪形或折线形的折流。
设置第一绝缘流道1301和第二绝缘流道1302形成间壁分布,这样,一方面使得第一绝缘流道1301与第二绝缘流道1302之间互不干扰,保证第一绝缘流道1301与第二绝缘流道1302之间的相互独立性,另一方面,第一绝缘流道1301与第二绝缘流道1302之间的间壁设计,有利于降低第一绝缘流道1301与第二绝缘流道1302之间的热传递效率,减少热量损失。
实施例12:
如图14所示,除上述任一实施例的特征以外,本实施例进一步限定了:第一管体131的一部分位于第二管体132内,另一部分位于第二管体132外,且第一管体131在第二管体132外的部分设有第二绝缘流道的进水口13021,也即第一管体131的长度较第二管体132的长度长,第二绝缘流道1302形成于第一管体131的第二通道1312,这样有利于增加第二绝缘流道1302的长度,进而利用水的等效电阻特性,进一步增强第二绝缘流道1302的防电性,避免 漏电风险,提升产品的使用安全。
第一绝缘流道的进水口13011和第二绝缘流道的出水口13022位于内胆11外。这样,便于连接进水管路及出水管路。
实施例13:
如图12、图13和图14所示,除上述任一实施例的特征以外,本实施例进一步限定了:管体1300具有接头134,接头134具有抵靠部1341,第二管体132的一端设有与缝隙133连通的开口1321,抵靠部1341与开口1321的壁抵靠配合。
举例地,接头134为三型聚丙烯接头134(PPR接头134),接头134内设有第一分隔板136,第一分隔板136将接头134内分隔为第一子流道13401和第二子流道13402,第一管体131内设有分隔结构(例如分隔板),分隔结构将第一管体131分隔成第一通道1311及第二通道1312,接头134的一端与第一管体131的一端对应连接,且接头134的第一分隔板136与第一管体131的分隔结构对应连接,例如,接头134与第一管体131热熔连接,使得第一子流道13401与第一绝缘流道1301对应连通,第二子流道13402与第二绝缘流道1302对应连通。
其中,接头134的侧壁上邻近抵靠部1341的一端凹陷形成有凹口1342,凹口1342作为第一绝缘流道的出水口13012,这样有利于充分利用缝隙133,进一步延长第一绝缘流道1301的长度,进一步增强第一绝缘流道1301的防电性,避免漏电风险,提升产品的使用安全,此外,第一绝缘流道的出水口13012位于管体1300上靠下的一侧,这样,有利于避免经第一绝缘流道的出水口13012流出的冷水对内胆11中的水扰动。
在另一个实施例中,接头134设有多个凸起,多个凸起形成抵靠部1341,多个凸起沿开口1321的边缘间隔的分布,相邻凸起之间限定出排水口,排水口作为第一绝缘流道的出水口13012。
在另一个实施例中,第二管体132的侧壁上设有一个或多个排水孔1322,一个或多个排水孔1322作为第一绝缘流道的出水口13012。
当然,上述形式也可以任意组合。
此外,本方案中,第一绝缘流道的出水口13012和第二绝缘流道的进水口 13021之间具有一定的距离,避免水在第一绝缘流道1301内沿第一绝缘流道的出水口13012排出后,立即沿第二绝缘流道的进水口13021进入第二绝缘流道1302,降低第一绝缘流道1301和第二绝缘流道1302之间蹿流风险,举例地,设计第一绝缘流道1301供冷水流入,第二绝缘流道1302供热水流出,通过增加第一绝缘流道的出水口13012和第二绝缘流道的进水口13021之间的距离,避免冷水未经加热即沿第二绝缘流道的进水口13021进入第二绝缘流道1302,保证热水的温度,且通过冷水在一侧流入,热水在另一侧流出,有利于减少冷热中和的消耗,进一步保证热水的温度。
进一步地,第一绝缘流道的出水口13012和第二绝缘流道的进水口13021位于第一管体131上相对的两侧,使得第一绝缘流道的出水口13012和第二绝缘流道的进水口13021之间具有一定的距离,避免水在第一绝缘流道1301内沿第一绝缘流道的出水口13012排出后,立即沿第二绝缘流道的进水口13021进入第二绝缘流道1302,降低第一绝缘流道1301和第二绝缘流道1302之间蹿流风险,举例地,设计第一绝缘流道1301供冷水流入,第二绝缘流道1302供热水流出,通过增加第一绝缘流道的出水口13012和第二绝缘流道的进水口13021之间的距离,避免冷水未经加热即沿第二绝缘流道的进水口13021进入第二绝缘流道1302,保证热水的温度,且通过冷水在一侧流入,热水在另一侧流出,有利于减少冷热中和的消耗,进一步保证热水的温度。
实施例14:
如图9和图11所示,除上述任一实施例的特征以外,本实施例进一步限定了:第一管体131为三型聚丙烯管(PPR管)。三型聚丙烯管具有环保、轻质高强、耐腐蚀、内壁光滑不结垢、使用寿命长的优点。
第二管体132为第一管套,这样,第二管体132具有一定的绝缘特性,进一步增加产品的防电效果。
当然,在其他实施例中,也可以设计第二管体132外套装有第一管套。
第一管体131的一部分位于第二管体132内,另一部分位于第二管体132外,且第一管体131在第二管体132外的部分套装有第二管套137。这样,第一管体131在第二管体132外的部分具有一定的绝缘特性,进一步增加产品的防电效果。
进一步地,第一管体131在第二管体132外的部分和第二管套137通过固定销、螺钉胶粘等方式连接。
