In actual use, the water supply pipe is connected with the water inlet 21, and the water outlet 31 is connected with a water terminal (such as a shower or a faucet). When the user opens the water terminal and uses hot water, then the water in the delivery pipe enters into first body 2 via water inlet 21, and the water that enters into in first body 2 will be handled through water treatment component 4 earlier to carry out antibacterial and the processing of inhibiting the dirt to water, and then reach the effect of demineralized water.

The softened water continues to flow and is heated by the heat generated by the electric heating part 1, and the heated water flows into the second pipe 3 through the auxiliary inlet 32 and is output from the second pipe 3.

On one hand, an installation space is formed between the first pipe body 2 and the second pipe body 3 to place a water treatment part 4, so that water flows enter the first pipe body 2 and then are treated by the water treatment part 4; on the other hand, a circuitous pipeline is formed between the first pipe body 2 and the second pipe body 3, so that the water entering the first pipe body 2 is prevented from flowing out quickly along with the water flow, the water entering the first pipe body 2 is ensured to be fully contacted with the water treatment component 4, and the requirement of water treatment is met.

In some embodiments, the positions of the water inlet 21 and the water outlet 31 can be arranged at the same end of the first pipe 2 and the second pipe 3, so that the inflowing water flows along the length direction of the first pipe 2 and then flows along the length direction of the second pipe 3 in the opposite direction. In this way, it is more beneficial for the water to be heated uniformly, so that the water outlet 31 outputs water with uniform temperature.

Specifically, when the instant electric water heater is opened again, because all there is a certain amount of hot water in first body 2 and the second body 3, like this, after cold water reenters first body 2, can carry out the heat absorption cooling to the water that flows out in the second body 3 to avoid or reduce and lead to delivery port 31 high temperature by the reheat because of the hot water that all exists in first body 2 and the second body 3, more be favorable to improving user experience nature.

In another embodiment, in order to achieve uniform heating of the inflowing water, the method further comprises: and the spiral plate 5 is arranged around the second pipe body 3, and extends along the length direction of the second pipe body 3.

Specifically, the spiral plate 5 is located in the first pipe body 2 and distributed around the second pipe body 3, and the spiral plate 5 can guide the water flow in the first pipe body 2, so that the water flow spirally flows between the first pipe body 2 and the second pipe body 3. Therefore, the flowing path of the water flow can be effectively prolonged, and the water flow can be uniformly heated.

Wherein the spiral plate 5 is arranged on the second tube body 3. Specifically, the spiral plate 5 is integrally of a spiral structure and sleeved outside the second pipe body 3, and the spiral plate 5 is fixedly installed. The spiral plate 5 may be welded to the second tubular body 3, or the spiral plate 5 may be bonded to the second tubular body 3. The specific fixing connection manner of the spiral plate 5 and the second tube 3 is not limited and described herein.

In addition, for ease of installation and positioning, the outer edge of the spiral plate 5 is attached to the inner pipe wall of the first pipe body 2. Specifically, insert second body 3 back in first body 2, because the edge of spiral board 5 pastes the inner wall that leans on at first body 2, and then make the second body 3 of unsettled in first body 2 can be better support and the location. And, because the edge of the spiral plate 5 is attached to the inner wall of the first tube 2, the water flowing from the water inlet 21 is guided and conveyed by the spiral plate 5, so as to ensure the heating uniformity of the water flow.
