The utility model relates to a domestic solar water heater with an integrated exhaust pipe, which belongs to the technical field of solar water heater. The metal outer pipe of the exhaust pipe is provided with upper and lower orifices, the elbow at the lower end of the inner pipe passes through the upper orifices and is fastened with a single end Union, and an outer wire elbow passes through the lower orifices and is fastened with a single end Union, and the inner space of the outer pipe is filled with polyurethane insulation material; the upper orifice union is connected with the exhaust port of the insulation water tank, and the lower orifice union is connected with the water inlet belt of the insulation water tank; the other end of the insulation water tank is covered with the hot water outlet A straight four-way metal pipe fitting is fastened at the water inlet, and the upper opening of the pipe fitting is fastened with a one-way air inlet valve with heat preservation effect. Advantages: the exhaust pipe can be stably and vertically fixed, which can effectively protect the heat in the hot water tank from loss; the air inlet valve with heat preservation effect can prevent the air inlet valve from freezing when the climate is cold; when the air inlet is blocked due to special reasons of the exhaust pipe, the air inlet valve can automatically open the air inlet valve to let the inner barrel of the heat preservation water tank not be sucked.

一体式排气管的家用型太阳能热水器
本技术属太阳能热水器
技术介绍
传统的顶水方式安装的家用型太阳能热水器水箱的排气管都是捆绑在水箱外某一物体上,例如一根竖直的木棍上来固定,以确保排气管不会弯曲,变形,脱落。这样做虽然短时间内不会出问题,可是时间长了以后,因捆绑的部件松动,风化,腐蚀导致排气管的弯曲、变形、脱落,最终因排气管排气不畅而引起保温水箱的吸瘪或胀裂。此外传统的排气管只是一根普通的水管,不具有保温和抗冻的性能,此外,当排气管出现其他特殊原因导致进气不畅时,也会引起保温水箱被吸瘪,给用户造成一定的安全隐患和经济损失。本专利申请人在先的专利号为ZL201520510375.2的中国专利文件“进排气双保险的家用型太阳能热水器”,公布了如下结构:水箱一侧端盖下部设进水口的位置紧固一口径为25mm的不锈钢内螺纹正三通管件,该不锈钢正三通的三个敞口,一个敞口朝上,一个敞口与外部进水口连接,一个敞口与水箱进水口紧固相通,不锈钢正三通朝上的敞口与一根长度为240mm,直径为20mm,壁厚为2mm的下端具有外螺纹的不锈钢管紧固,不锈钢管的下端内部为密封状态;在不锈钢管的外部再套入一根长度为240毫米,直径为25mm,壁厚为2mm的上端具有外螺纹的不锈钢管,将不锈钢管具有外螺纹的上端与端盖上部设排气口位置紧固的不锈钢正三通朝下的敞口紧固,不锈钢管的上端内部为密封状态。由于连接紧固排气口和进水口的两根金属管件外面都没有保温材料,受管道热量的传递的影响,长时间的裸露在外的金属管件会造成保温水箱内部热量的流失。本专利申请人在先的专利号为ZL201520601386. ...
