Description

非金属内胆及具有其的电热水器
本申请要求在2022年06月02日提交中国专利局、申请号为202210624531.2的中国专利申请的优先权，要求在2022年06月02日提交中国专利局、申请号为202221387758.1的中国专利申请的优先权，该两件申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及电热水器技术领域，例如涉及一种非金属内胆及具有其的电热水器。
背景技术
电热水器的内胆作为储水部件，大多为金属内胆，同时为了加热金属内胆内的水，还需要于内胆内装配加热管。在安装加热管时，通常是在金属内胆的胆口处焊接一内胆法兰，随后加热管安装于加热管法兰上，通过内胆法兰和加热管法兰固定连接，实现加热管于金属内胆的安装。
然而上述内胆多采用不锈钢金属或搪瓷做成，这些类型的内胆能够满足承压要求，但是其存在绝缘系数较低、防腐能力差，加工成本高的问题。因此，市场上开始用非金属内胆(如塑料内胆)替代不锈钢金属或搪瓷内胆，但是由此也产生了以下问题：为了实现与加热管法兰的固定连接，依旧需要在非金属内胆的胆口处设置内胆法兰。
相关技术中，内胆法兰通常是通过熔接的方式嵌入非金属内胆的胆口处，随后与加热管法兰固定连接，这种结构在非金属内胆承受较大的压力时，非金属内胆的胆口与内胆法兰熔接的位置会因压力过大产生裂痕，进而出现漏水的情况。
为避免内胆法兰与非金属内胆之间熔接，相关技术多采用如下方案：在非金属内胆的胆口内成型一具有内螺纹的固定件，内胆法兰具有外螺纹，内胆法兰与固定件螺纹连接，固定有加热管的加热管法兰再与内胆法兰连接。该方案的不足之处在于，存在固定件与内胆法兰之间、内胆法兰与加热管法兰之间等多个接口，接口数量较多，容易造成工艺上的安装缺陷，增加了漏水的机率，从而导致影响电热水器的使用性能，严重的甚至会产生安全隐患。

实施例一
如图1至图7所示，本申请实施例的非金属内胆包括内胆本体10、加强层20和内胆法兰30，其中，内胆本体10的一端形成有胆口11，胆口11的外侧设置有环绕胆口11的限位环形部12；加强层20覆盖于内胆本体10的外周；内胆法兰30的内端由限位环形部12限位固定，内胆法兰30的外端固定于内胆本体10与加强层20之间。通过在胆口11外侧设置环绕胆口11的限位环形部12，并使内胆法兰30的内端由限位环形部12限位固定，外端固定于内胆本体10与加强层20之间，使得内胆法兰30与内胆本体10能够紧密结合，且不存在熔接点，避免了非金属内胆在承受压力较大时熔接位置的漏水问题；另外，内胆法兰30与内胆本体10直接连接，省去了固定内胆法兰30的固定件，减少了固定件与内胆法兰30之间的连接接口，从而降低了漏水的几率。
限位环形部12可以是由胆口11的端部朝背离胆口11的中心方向与内胆本体10一体成型，还可以是设置在胆口11外侧的一个独立的部件，可根据需要进行设置。
参照图3至图7，内胆法兰30包括内端环形部31、外端环形部33以及连接于内端环形部31和外端环形部33之间的凸起连接部32，内端环形部31由限位环形部12限位固定，外端环形部33固定于内胆本体10与加强层20之间，凸起连接部32设置为与加热管法兰连接。通过将内胆法兰30设置为包括内端环形部31、凸起连接部32和外端环形部33三部分，使得内胆法兰30与内胆本体10之间，以及内胆法兰30与加热管法兰之间的连接更加简便，内胆法兰30的结构更加合理。
内端环形部31和限位环形部12可以均为平板形，通过将内端环形部31抵压于限位环形部12的下端，来对内端环形部31进行限位固定，参见图7。或者，限位环形部12的截面还可以为U形，相应的，内端环形部31的截面可以为L形，内端环形部31的水平部与凸起连接部32连接，内端环形部31的竖直部插设于限位环形部12的限位槽内，从而实现限位环形部12对内端环形部31的限位。
一实施例中，内胆法兰30的外端环形部33呈弧形，外端环形部33能够与内胆本体10的外表面贴合。通过将内胆法兰30的外端环形部33设置为弧形，并与内胆本体10的外表面贴合，能够提高外端环形部33固定于内胆本体10与加强层20之间的稳定性，且能够提高加强层20的平整度，保证加强层20的强度。
一实施例中，凸起连接部32与内端环形部31以及与外端环形部33之间均为圆弧过渡。通过将凸起连接部32设置为与内端环形部31和外端环形部33之间均为圆弧过渡，能够降低凸起连接部32与内端环形部31和外端环形部33之间连接处的应力集中，提高内胆法兰30的强度。
内胆本体10的外表面开设有环形的容置槽，内胆法兰30的外端环形部33设置于容置槽内。通过在内胆本体10的外表面开设容置槽，且使内胆法兰30的外端环形部33设置于容置槽内，能够使得内胆法兰30的外端环形部33的外表面与内胆本体10的外表面平齐，从而能够保证加强层20的平整性，避免增加加强层20的厚度，保证成本。
一实施例中，内胆本体10的内表面正对容置槽设置有环形的加厚部13。通过在内胆本体10的内表面正对容置槽的位置设置环形的加厚部13，能够补强由于内胆本体10的外表面开设容置槽而削弱的强度，从而保证内胆本体10的整体强度。一实施例中，加厚部13的厚度大于或等于容置槽的深度，通过将加厚部13的厚度设置为大于或等于容置槽的深度，能够使得补强的强度大于削弱的强度，从而保证内胆本体10的整体强度不降低。
于本实施例中，加强层20由纤维缠绕而成。加强层20是由纤维增强树脂复合材料制作，将浸润树脂后的长丝纤维缠绕在内胆本体10上，纤维可采用玻璃纤维、碳纤维、凯夫拉纤维等，缠绕完成后进行高温固化，固化后的纤维缠绕层是内胆本体10的承压结构层。
