Preferably, the overflow damper box being convenient to the overflow of heat conductive insulating media expansion is also provided with on the upside of described heating container.
Preferably, the auto-power-off device when heat conductive insulating medium liquid level is too low in heating container is also provided with in described overflow damper box.
Preferably, the arranged outside of described heating container has lagging casing, and the middle part of heating container is provided with the heating cavity installed heat-generating pipe and contain heat conductive insulating medium, is provided with heat preservation layer between heating cavity and lagging casing.
Preferably, described heat conductive insulating medium is heat conductive insulating oil.
Preferably, the insulating carriage for supporting heating container is provided with in the upper cover on described inner bag top.
Preferably, the water inlet bottom described inner bag is connected with a drainpipe, drainage pipe end is provided with the draining valve being convenient to inner water tank draining.
Preferably, described pipeline is insulation tube.
The beneficial effects of the utility model are:
The utility model changes the direct-heating type structure of water heater into heat exchange type structure through heat-conducting medium transferring heat, and heat-conducting medium adopts the heat conductive insulating oil with insulation characterisitic, heat exchanger is made to become an insulation calandria with this, inner water tank water body is insulated mutually with the heat-generating pipe in heating container heating cavity all the time isolate, thus reach the effect that water power is separated completely, fundamentally solve existing water heater easily to leak electricity, the problem that water body can be charged.During such use, user uses during water in water heater and also can not get an electric shock, and makes the electric leakage security risk of water heater reduce to zero.
