Portion, the ring portion outer diameter and is adapted for insertion into the bellows.
The utility model has the beneficial effects that:
Two liners by connection tube assembly connection, are connected to one end insertion the of tube assembly by the electric heater of the utility model
The phenomenon that at the top of one liner, the other end is inserted into the bottom of the second liner, rises cold water sedimentation due to hot water, connection tube assembly make the
The water body of higher temperature at the top of one liner enters the second liner at the bottom, thus enable the water body to circulate gradually heat temperature raising,
It is left at the top of the second liner again, to solve the problems, such as the heat waste generated due to large capacity, makes water heater more
Energy conservation.Double inner-tube structures make the shell platypelloid type of water heater, improve aesthetic appearance.
Tube assembly is connected to using metal bellows as external communicating pipe, keeps its curved position diameter of installation adjustable, thus
It is suitable for the dual-bottle type water heater product of different model.
The first pipe fitting for being connected to tube assembly is metal tube, is embedded in the second pipe fitting of nylon material, the second pipe fitting in its bottom
It is mounted in the bottom sleeve of the first liner, is achieved the purpose that easy to install, structurally reasonable by interference fit.It is connected to tube assembly
Third pipe fitting is located in the bottom sleeve of the second liner, and top sidewall offers several effluent troughs, makes to be discharged from the side of pipeline
The outflow of wall level is conducive to the hot water delivery rate for improving product to reduce the disturbance to the second liner water body.
