Example 1

As shown in fig. 1, 2, and 3, the dual-bladder water heater includes a first bladder 100 and a second bladder 200, wherein the first bladder 100 is disposed above the second bladder 200. The first inner container 100 is connected with the second inner container 200 by a connecting pipe 300, and the double-container water heater further comprises a water inlet pipe 400 and a water outlet pipe 500.

A first through hole 110 is formed below the first inner container 100, a second through hole 210 is formed above the second inner container 200, the connecting pipe 300 is communicated with the first inner container 100 through the first through hole 110, and the connecting pipe 300 is communicated with the second inner container through the second through hole 210.

One end of the water inlet pipe 400 is disposed below the second inner container 200 and connected to an external water source, and the other end of the water inlet pipe 400 extends into the second inner container 200. One end of the water outlet pipe 500 is disposed below the second inner container 200 and connected to an external water outlet pipe, and the other end of the water outlet pipe 500 extends into the first inner container 100 through the connection pipe 300.

Because the second inner container 200 is communicated with the water inlet pipe 400, the cold water is mainly used in the second inner container 200, the first inner container 100 is communicated with the water outlet pipe 500, the hot water is mainly used in the first inner container 100, and the water temperature of the upper layer of the first inner container 100 is higher than the water temperature of the lower layer of the first inner container 100.

In this embodiment, the first inner container 100 and the second inner container 200 are communicated with each other by a connecting pipe 300. The cold water introduced into the second inner container 200 from the water inlet pipe 400 flows into the first inner container 100 from the connection pipe 300. Because the water inlet pipe 400 is directly connected with an external water source, the external water source has higher water pressure, and cold water flows into the first inner container 100 with higher pressure after flowing in from the water inlet pipe 400, and can rush into the hot water layer of the first inner container 100, so that the outlet water temperature of the double-container water heater is influenced.

In this embodiment, a water return pipe module 600 is disposed in the connection pipe 300, the water return pipe module 600 includes a water return pipe body 610, and a plurality of third through holes 611 are opened on a side wall of the water return pipe body 610.

As shown in fig. 4, the reverse water pipe module 600 further includes two connecting portions 620, the two connecting portions 620 are disposed at two ends of the reverse water pipe body 610, the reverse water pipe module 600 is sleeved outside the water outlet pipe 500, and the water outlet pipe 500 and the connecting portions 620 are hermetically connected to the reverse water pipe body 610.

Specifically, the connecting portion 620 is an annular cylinder, the inner side wall of the annular cylinder is connected with the outer side wall of the water outlet pipe in a sealing manner, and the outer side wall of the annular cylinder is connected with the inner side wall of the water return pipe body 610 in a sealing manner. The first end of the water returning pipe body 610 is positioned in the first inner container 100, and the second end of the water returning pipe body 610 is positioned in the second inner container 200.

In the above connection manner, while the positioning of the connection portion 620 is realized, the cold water in the second inner container 200 enters between the water return pipe body 610 and the water outlet pipe 500 from the plurality of third through holes 611 formed in the second end of the water return pipe body 610, and flows out into the first inner container 100 from the plurality of third through holes 611 formed in the first end of the water return pipe body 610. Thereby slowing down the flow rate of cold water entering the first inner container 100 from the second inner container 200 and avoiding cold water directly entering the hot water layer of the first inner container 100, thereby not influencing the outlet of the hot water of the first inner container 100.

In order to allow sufficient cold water to smoothly enter between the reverse water pipe body 610 and the water outlet pipe 500 from the third through holes 611 at the second end of the reverse water pipe body 610, the third through holes 611 are uniformly distributed along the circumferential direction and the axial direction of the reverse water pipe body 610.

In this embodiment, in order to further slow down the flow rate of the cold water flowing from the second inner container 200 into the first inner container 100, a buffering ring 630 is further provided. The inner side wall of the buffer ring 630 is connected with the outer side wall of the water outlet pipe 500 in a sealing manner, and the outer side wall of the buffer ring 630 is connected with the inner side wall of the water return pipe body 610. A plurality of fourth through holes 631 are formed between the upper and lower surfaces of the buffer ring 630, and the plurality of fourth through holes 631 are uniformly distributed on the buffer ring 630.

The water entering between the water returning pipe body 610 and the water outlet pipe 500 from the third through holes 611 formed in the second end of the water returning pipe body 610 needs to pass through the fourth through holes on the buffer ring 630 and then enter between the first end of the water returning pipe body 610 and the water outlet pipe 500, and then flows out to the first inner container 100 from the third through holes 611 formed in the first end of the water returning pipe body 610. Thereby further reducing the flow rate of the cold water from the second inner container 200 into the first inner container 100.

Specifically, the buffer ring 630 is disposed in the second liner 200, i.e., between the first end of the reverse water pipe body 610 and the water outlet pipe 500. The speed of cold water flowing into the first inner container 100 can be effectively reduced.

In this embodiment, the number of the connection pipes 300 is several, and is set according to specific situations. The number of the water return pipe modules 600 is also several.
