具体实施方式
能详细了解本发明的技术特征及实用功效,并可依照说明书的内容来实现,兹进一步以如附图所示的较佳实施例,详细说明如后:
请参看图1与图2,本发明的陶瓷加热片结构的第一实施例具有一圆盘状的加热片10,其于相对两侧分别形成一上发热面11与一下发热面12,该加热片10上穿设有多个通孔13连通该上发热面11与该下发热面12,且该各通孔13的内周壁形成一发热内面130,该发热内面130分别电连接于该上发热面11与该下发热面12,而形成一电阻回路,该电阻回路的配置方式属于现有技术,本发明不限制该电阻回路为何种型态;
进一步,请参看图3与图4,该加热片10的该上发热面11与/或该下发热面12上设有电阻值为10欧姆以下的金属导电镀膜层111、121,该各通孔13的该发热内面130上则设有电阻值为20欧姆以上的金属导电镀膜层131;
该加热片10的该上发热面11上设有一第一绝缘区域,该第一绝缘区域包含多个第一臂部140,各该多个第一臂部140自上发热面11的中央延伸至该发热面的周缘;换句话说,第一绝缘区域是由上发热面11的中央向外延伸而呈一辐射状;
该加热片10的该下发热面12上设有一第二绝缘区域,该第二绝缘区域包含多个第二臂部150,各该多个第二臂部150自该下发热面12面的中央延伸至该另一发热面的周缘;换句话说,第二绝缘区域是由下发热面12的中央向外延伸而呈一辐射状;于垂直该加热片10的该上发热面11及该下发热面12的方向上,其中一该第二臂部150正对其中一该第一臂部140,换句话说,其中一该第二臂部150与其中一 该第一臂部140相重叠;其余该第二臂部150与其余该第一臂部140交错间隔,换句话说,两相邻的第二臂部150会有一第一臂部140;
通过上述结构,该上发热面11上,与其中一该第二臂部150正对的该第一臂部140的两侧分别形成互不通电的一输入区域112及一输出区域114,即,该与一该第二臂部150正对的第一臂部140与其所相邻的两第一臂部140之间分别形成该输入区域112及该输出区域114;其余相邻的该第一臂部140之间分别形成不通电的一第一传导区域113,且各该第一传导区域113与该输入区域112及该输出区域114互不通电;该下发热面12被各两相邻的该第二臂部150分隔成互不通电的一第二传导区域120;该第二传导区域120的数量比该第一传导区域113的数量多一个;
于垂直该加热片10的该上发热面11及该下发热面12的方向上,该第一传导区域113与两相邻的该第二传导区域120重叠;而相对地,其中一该第二传导区域120与所对应的一该第一传导区域113重叠外更与该输入区域112重叠,且另一该第二传导区域120除与所对应的另一该第一传导区域113重叠外更与该输出区域114重叠。因此,电流通的路径可依序为:输入区域112、一第二传导区域120、一第一传导区域113、另一第二传导区域120、另一第一传导区域113……又另一第二传导区域120、输出区域114。当第一臂部140及第二臂部150的数量越多,第一传导区域113及第二传导区域120的数量相应地也越多。
请参看图1与图2,如本发明的第一实施例中,该加热片10的该上发热面11的第一绝缘区域共具有三个第一臂部140,且其中两第一臂部140连成一直线而剩余的第一臂部140则沿垂直该两连成一线的两第一臂部140延伸,因此本发明的第一实施例中的第一绝缘区域为一T型绝缘区域14;当然,于其他实施例中,三第一臂部140间的夹角并不以此为限;绝缘区域14将该上发热面11分隔成互不通电的一输入区域112、一第一传导区域113、一输出区域114;该加热片10的该下发热面12的第二绝缘区域具有两连成一直线的第二臂部150,且对应T型绝缘区域14的中线位置形成一直线绝缘区域15,将该下发热面12分隔成左右互不通电的两第二传导区域120;
该加热片10于外周面可进一步设有一输入端子16与一输出端子17,该输入端子16电连接于该上发热面11的该输入区域112,该输出端子17电连接于该上发热面11的该输出区域114;
本发明的陶瓷加热片结构的第一实施例于使用时,请参看图3与图5,先将电流通过该输入端子16输入该上发热面11的该输入区域112,接着电流通过对应该输入区域112的该些通孔13传递至该下发热面12右侧的该第二传导区域120,接着再通过对应该第一传导区域113的该些通孔13传递至该上发热面11的该第一传导区域113,接着电流通过对应左侧的该第二传导区域120的该些通孔13传递至该下发热面12左侧的该第二传导区域120,然后通过对应该输出区域114的该些通孔13传递至该上发热面11的该输出区域114,最后再从该输出端子17流出,即完成一圈电阻回路的循环。
本发明的陶瓷加热片结构,由于该上发热面11与/或该下发热面12上设有电阻值为10欧姆以下的金属导电镀膜层111、121,因此,当电流通过该上发热面11与/或该下发热面12的各区域时,所产生的热能较少、温度较低,适用于组装时作为安装接触面,或是提供低温加热的需求,再者,由于该各通孔13的该发热内面130上设有电阻值为20欧姆以上的金属导电镀膜层131,因此,当电流通过该各通孔13的该发热内面130时,所产生的热能较多、温度较高,适用于加热通入吹风机的风或加热通入电暖炉的空气,可用以提供高温加热的使用需求。
此外,由于加热片10上所设计的电阻回路路径越长时,电流循环的路径也会越长,因此可有助于提升发热增温的效率,达到快速升温、加热温度高的功效。
请参看图6与图7,本发明的陶瓷加热片结构的第二实施例与第一实施例大致相同,但是加热片10A上的电阻回路型态不同,该加热片10A的该上发热面11A上的第一绝缘区域共具有两个第一臂部140,且两第一臂部140连成一直线,因此第一绝缘区域为延伸至周缘的一直线绝缘区域18A,将该上发热面11A分隔成互不通电的一输入区域112A与一输出区域114A;该加热片10A的该下发热面12A则无设置绝缘区域,而形成全面积的该第二传导区域120A,该加热片10A的该 输入端子16电连接于该上发热面11A的该输入区域112A,该输出端子17电连接于该上发热面11A的该输出区域114A,则该加热片10A上便形成第二实施例的电阻回路;
本发明的陶瓷加热片结构的第二实施例于使用时,请参看图8,先将电流通过该输入端子16输入该上发热面11A的该输入区域112A,接着电流通过对应该输入区域112A的该些通孔13传递至该下发热面12A的该第二传导区域120A,接着再通过对应该上发热面11A的该输出区域114A的该些通孔13传递至该上发热面11A的该输出区域114A,最后再从该输出端子17流出,即完成一圈电阻回路的循环。
请参看图9至图11,本发明的陶瓷加热片结构的第三实施例与第一、第二实施例大致相同,但是加热片10B上的电阻回路型态不同。该加热片10B的该上发热面11B上的第一绝缘区域共具有五个第一臂部140,其中四个该第一臂部140将该上发热面11B分隔成四等份,而剩余的一该第一臂部将140其中一份进一步再分隔成二等份;该被进一步分隔成的二等份分别为该输入区域112B及该输出区域114B,而未被分隔的其余三份各为一第一传导区域113B;该加热片10B的该下发热面12B上的第二绝缘区域包含四个第二臂部150,其将下发热面12B分隔成四等份,该四等份分别为四个第二传导区域120B;
因此,电流通的路径可依序为:输入区域112B、一第二传导区域120B、一第一传导区域113B、另一第二传导区域120B、另一第一传导区域113B……又另一第二传导区域120B、输出区域114B,完成一圈电阻回路的循环;
本发明的陶瓷加热片结构主要是利用加热片10两侧中的至少一侧设置电阻值较低的金属导电镀膜层111、121,使加热片10的至少一侧表面发热的温度较低,适用于作为组装的安装接触面或是提供低温加热的需求,而加热片10的通孔13中的发热内面130上则设置电阻值较高的金属导电镀膜层131,使加热片10的通孔13内部发热温度较高,提供高温加热的使用需求,由此因应不同区域的作用与温度需求来提供适当的温度,增加安装与加热使用上的安全性。
由上述内容可知,不同的修改及改变可在不脱离本发明实质的精神及新颖概念的范围下加以达成,并且本发明披露的特定实施例并非 用以限制本发明,此一披露内容包含落入权利要求书的范畴下的所有修改。
