Problems solved by technology
[0003] First of all, its welding strength is not enough, and the welding process is difficult to realize the orthogonal relationship between the horizontal axis of the horizontal liner and the center line of the water pipe joint (for vertical electric water heaters, it is difficult to realize the vertical axis of the vertical liner and the water pipe joint). The parallel relationship between the center line), which is not conducive to the sealing connection between the water pipe joint and the water outlet pipe and the water outlet insulation pipe; thirdly, in order to make the connection between the water pipe joint and the water outlet pipe or the water outlet insulation pipe stable, it is necessary to fully ensure that the water pipe joint and the water outlet pipe Or the contact area between the water outlet insulation pipes, which directly increases the volume of the water pipe joints, making the water pipe joints occupy a large space, so a larger shell has to be used, which directly increases the product cost

An electric water heater comprises a housing, an inner container, a water outlet pipe, a water outlet insulating pipe and a water pipe connector, and is mainly and technically characterized in that, in arrangement, one end of the water pipe connector extends into the inner container, the water outlet pipe extends into the inner container after passing through the water pipe connector, the water outlet insulating pipe is hermetically connected with the water pipe connector, and the water outlet insulating pipe is communicated with the water outlet pipe. In the electric water heater provided by the invention, not only can the welding intensity between the water pipe connector and the inner container be enhanced effectively, which is favorable for a welding process, but also the sealing effects between the water pipe connector and the water outlet pipe as well as between the water pipe connector and the water outlet insulating pipe are ensured, further the space occupied by the water connector outside the inner container is saved, and the product cost is lowered.
Description
technical field [0001] The invention belongs to the field of electric water heaters, and in particular relates to an electric water heater. Background technique [0002] Existing electric water heaters are for fixing the water outlet pipe in the inner container, usually a water pipe joint is welded on the outer wall of the inner container, and the water outlet pipe passes through the water pipe joint and stretches into the inner container. The water outlet pipe is positioned by the water pipe joint like this, and communicates with the water outlet insulation pipe outside the inner bag simultaneously, to supply hot water to the user. And this connection mode that the water pipe joint is welded on the outer wall of the inner tank has the following defects: [0003] First of all, its welding strength is not enough, and the welding process is difficult to realize the orthogonal relationship between the horizontal axis of the horizontal liner and the center line of the water pip...
