Compared with the traditional water heater with one inner container, the double-container water heater has the advantage that the whole thickness of the water heater is thinner under the condition of the same volume. At present, how to reduce the gap between two inner containers of the double-container water heater is an effective measure for further reducing the overall size of the double-container water heater.

For a conventional water heater, as shown in fig. 1, 2, and 3, the two inner containers are respectively a third inner container 600 and a fourth inner container 700, and the two inner containers need to be communicated with each other by welding a water pipe seat 800 therebetween. Due to the limitation of the welding process, enough operating space must be left at the welding position between the two inner containers, so that the minimum distance between the two inner containers is limited.

In the present embodiment, as shown in fig. 4, 5, and 6, a communication portion 300 is provided between the first liner 100 and the second liner 200, and both ends of the communication portion 300 communicate with the first liner 100 and the second liner 200, respectively. The communication portion 300 is externally fitted with a sealing portion 400, and the sealing portion 400 seals a connection portion between the first inner container 100 and the communication portion 300 and a connection portion between the second inner container 200 and the communication portion 300.

In the present embodiment, the communication portion 300 includes a communication portion body 310 and a stopper portion 320. The communicating portion body 310 has a first communicating opening at one end and a second communicating opening at the other end, and the first communicating opening is communicated with the second communicating opening. The first communication port is communicated with the first inner container 100, and the second communication port is communicated with the second inner container 200. The stopper 320 is disposed on the outer side of the communicating portion body 310, one end of the stopper 320 abuts against the first liner 100, and the other end of the stopper 320 abuts against the second liner 200. Thereby realizing the position limitation of the first inner container 100 and the second inner container 200 by the limiting part 320.

Specifically, the limiting portion may be of an annular structure and is sleeved in the middle of the outer side of the communicating portion body 310. The upper end of the annular structure abuts against the first inner container 100, and the lower end of the annular structure abuts against the second inner container 200.

Specifically, the communication portion body 310 may have a hollow cylindrical structure.

Specifically, the sealing portion 400 is a gasket. The sealing ring is made of rubber, and can generate certain elastic deformation under the action of force.

One end of the sealing part 400 abuts against the first inner container, and the other end of the sealing part 400 abuts against the second inner container.

In the present embodiment, the clamp portion 500 is provided to improve the sealing performance of the sealing portion 400 with respect to the connection portion between the first inner container 100 and the communication portion 300 and the connection portion between the second inner container 200 and the communication portion 300. One end of the clamping portion 500 is connected to the first inner container 100, and the other end of the clamping portion 500 is connected to the second inner container 200, so that the distance between the first inner container 100 and the second inner container 200 is shortened by clamping the clamping portion 500, and the sealing portion 400 is further pressed, thereby enhancing the sealing performance of the sealing portion 400.

The clamp ring 500 may have various structures, which are not limited herein, and may clamp the first liner 100 and the second liner 200, so as to shorten a distance between the first liner 100 and the second liner 200.

The following is an example of a specific structure of the clamping portion 500: the clamping part 500 includes a clamping ring 510 and a bolt. The clamping ring 510 is a thin metal sheet having a certain amount of elastic deformation.

The clamping ring 510 is sleeved outside the first inner container 100 and the second inner container 200. A first through hole 511 and a second through hole are formed in the clamping ring 510, and bolts penetrate through the first through hole and the second through hole to clamp the clamping ring 510. So that the clamping ring 510 is clamped on the first and second inner containers 100 and 200. Thereby enhancing the sealing effect of the sealing part 400.

Specifically, the clamping ring 510 includes an open end, two connection plates 511 are respectively disposed at two ends of the open end, and a first through hole 511 and a second through hole are respectively disposed on the two connection plates 512. The bolts pass through the first through hole 511 and the second through hole of the two connecting plates 512 and are tightened by nuts, and the two connecting plates 512 receive the clamping force of the bolts, so that the open end of the clamping ring 510 is stressed and deformed, and the clamping force is applied to the first liner 100 and the second liner 200. Meanwhile, one end of the sealing ring is abutted against the first inner container 100, and the other end of the sealing ring is abutted against the second inner container 200, so that the sealing effect of the sealing ring on the connection parts of the first inner container 100, the second inner container 200 and the communicating part 300 is enhanced.

The clamping portion 500 may also take the form of a cable tie, which enables secure fastening.

In order to further increase the sealing effect of the sealing part 400, the clamping ring 510 and the sealing part 400 are disposed on the same cross section of the first and second inner containers 100 and 200. The clamping force of the clamping ring 510 can be applied in the radial direction of the seal portion 400 in its entirety, most effectively enhancing the sealing effect.

In order to facilitate the circulation of hot water and cold water between the first inner container 100 and the second inner container 200 and the arrangement of the water inlet pipe and the water outlet pipe between the first inner container 100 and the second inner container 200, two communicating parts 300 may be provided between the first inner container 100 and the second inner container 200.

In order to reinforce the sealing performance at the two communicating portions 300, sealing portions 400 are provided at the two communicating portions 300, and in order to reinforce the sealing effect of the sealing portions 400, a clamping portion 500 is provided at each sealing portion 400 for securing the sealing effect of the sealing portion.

The two clamping portions 500 are respectively disposed on the same plane as the two sealing portions 400 to apply a radial force to the sealing portions 400, thereby increasing a sealing effect.

Simultaneously, first inner bag 100 and second inner bag 200 all can receive the pressure of the water that holds from the inner bag under operating condition for first inner bag 100 and the outside inflation of second inner bag 200 can make sealing 400 receive further compressing tightly like this, so adopt sealing 400 suit to seal at the junction of first inner bag 100 and intercommunication portion 300, second inner bag 200 and intercommunication portion 300, and is sealed reliable, can not appear inefficacy in the use.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
