Or replacement heater element.Heater element uses electromagnetic heating coil in Fig. 1 or Fig. 2, and insulating layer is arranged in heating pipe outer wall
3, the outer brushing coatings of insulating layer form insulating layer.
Heater element uses resistance wire class heating coil in fig. 3, so insulating layer 3 is arranged in heater element outer layer,
Heater element is wrapped in insulating layer, brushing coatings form insulating layer in heating pipe outer wall, and in heater element
Outside is provided with protective cover 6, and heater element is covered completely, to play the role of protecting heater element；Shown in attached drawing 3
Heater element is also possible to one of carbon film fever casing, charcoal trichite thermal sleeve, infrared emission quartz socket tube.
The utility model is horizontally installed to the outside of electric water-heating apparatus, the water storage of heating tube and electric water-heating apparatus when in use
Case connection.The water tank of the utility model and electric water-heating apparatus is connected with two ways, and a kind of mode is connected by ring flange,
As shown in attached drawing 1 and attached drawing 3, ring flange 4 is provided on the port of heating tube；Another way is grafting, such as 2 institute of attached drawing
Show, heat and be not provided with ring flange on pipe port, but reserve one section of inserting section, in inserting section after set sealing shroud and on water tank
Reserved spliced eye seals cooperation.
The utility model is in application referring to attached drawing 4,5, and attached drawing 4 is by taking horizontal boilers heated electrically as an example, the electricity of the utility model
Heater 11 passes through the closed company of mounting hole being arranged outside the water tank 7 for being arranged in and heating the ring flange and boilers heated electrically on pipe port
It connects, multiple electric heaters can be connected on the water tank of boilers heated electrically as needed, each electric heater is horizontal connection
On water tank, it may be assumed that the axis of heating tube is parallel to the horizontal plane.The cabinet of the water tank is thermal-insulating body, it may be assumed that water tank case
Body is made of liner, shell and the insulating layer being clipped between liner and shell, manhole 8 is equipped at the top of water tank, in water storage
The top of case side is equipped with overflow port 12, hot water outlet 13, and lower part is equipped with water return outlet 14, sewage draining exit 15, another in water tank
The top of side is equipped with boiler water filling mouth 10, instrument installing port 9.By taking vertical electric boiler as an example, the electricity of the utility model adds attached drawing 5
Hot device 11 passes through the closed company of mounting hole being arranged outside the water tank 7 for being arranged in and heating the ring flange and boilers heated electrically on pipe port
It connects, multiple electric heaters can be connected on the water tank of boilers heated electrically as needed, each electric heater is horizontal connection
