Abstract

多层吹塑的电热水器内胆,所述多层吹塑是指内胆吹塑时由一层以上不同性能材料制成,而且是一次性成型,用以提高热变形温度和强度,若能满足强度时单层吹塑也可以;同时,在塑料内胆外表局部或全部包裹一层金属薄板;其上制有与外壳连接和悬挂的承力点。

Description

多层吹塑的电热水器内胆
技术领域
本发明涉及多层吹塑的电热水器内胆,主要涉及封闭式或出口敞开式塑料材料制造的内胆,并在其外部,局部或全部包裹一层金属薄板的结构。 
背景技术
中国专利公开号CN101968263A公开了“中空吹塑成型的热水器内胆”,该专利申请存在以下缺陷: 
1、CN101968263A的权利要求第2-3行“圆桶体的侧壁(1)上设计三条以上凸边(2)”,此种结构,内装热水后,水箱会膨胀和伸长,不能使用。 
2、CN101968263A的权利要求第7-8行“立式的(中轴线在竖直方向)在其下端面(5)的中心处开一个孔(6)”及“横式的(中轴线在水平方向)在其侧面(1)的中心处开一个孔(6)”;从附图1和附图2看出,孔(6)内外都是平口,这种开口方式,目前任何单位或个人都无法使该专利申请的热水器内胆密封装水,更不能承压。 
3、按照GB4706.12-2006 22、101“直接与水源连接的密闭式热水器,其额定压力至少应为0.6Mpa,试验压力为2倍,即1.2Mpa”;该专利申请的内胆不能承受此压力,不能制成密闭式热水器。 
4、该专利申请的中空吹塑的热水器内胆,装水后必须承受50-100kg的悬挂重量,且必须与外壳连接,该专利申请无此项功能描述。 
发明内容
本发明对“中空吹塑成型的热水器内胆”进行改进,采用多层吹塑工艺制造内胆,所述多层吹塑是指内胆壁吹塑时由一层及以上不同材料制成,是用多个料斗同时送入几种性能不同的原料,而且是一次性成型,用以提高热变形温度和强度,若能满足强度时单层吹塑也可以;同时,在塑料内胆外表局部或全部包裹一层金属薄板2,其上制有与外壳连接和悬挂的承力点10;内胆一端开有带法兰边向外扩的喇叭形口3;对喇叭型的孔口3处的密封方法是用盖5及对开的两个半圆形夹紧片6,通过多个镙钉8将密封件7及塑料内胆上的有法兰边并向外扩的喇叭形口3和法兰盖4夹紧,保证承受设定压力不泄漏;综上所述,其特征是:①塑料内胆,由一层及以上不同性能的材料制成;②塑料内胆外表局部或全部包裹一层金属薄板2,其上制有与外壳连接和悬挂的 承力点10;③塑料内胆一端开有带法兰边向外扩的喇叭形口3。 
本发明的优点是以塑料替代钢,可降低制造成本;同时不需要技术熟练的工人,而且强度高,承受压力大,不会漏水,提高了产品质量。 
附图说明
图1有法兰边向外扩的喇叭形口的多层或单层塑料内胆示意图; 
图2是图1A-A截面图; 
图3、图4塑料内胆密封结构示意图; 
具体实施方式
下面结合附图进行说明,附图中电热水器塑料内胆1、带有连接和悬挂承力点的金属薄板2、有法兰边向外扩的喇叭口3(或称孔3)、法兰件4、盖5、两个半圆形夹紧件6、密封件7、镙钉8、多层或单层吹塑的内胆壁9、悬挂承力点10、电热管11。 
图1为多层或单层的电热水器内胆,并在塑料内胆1外表局部或全部包裹带有连接和悬挂承力点10的金属薄板2。 
图1中、塑料内胆右侧制有法兰边向外扩的喇叭形口3(或称孔3),图3、图4是法兰边向外扩的喇叭形口进行密封的结构示意图,有法兰边向外扩的喇叭形口3上安装法兰件4(法兰件4上可装电热管、测温管或限温温控器),用盖5及对开的两个半圆形夹紧片6,用多个镙钉8将密封件7及塑料内胆上的有法兰边并向外扩的喇叭形口3和法兰件4夹紧,构成密闭容器。 
本发明适用于立式和卧式各型电热水器。
