The electrothermal steam of prior art, water heater all are that the heating element that connects ac high voltage source is soaked in water by heat exchanger, directly utilize heat transfer water.There are following shortcoming in this electrothermal steam, water heater: the electric heating generating means of (1) band High Level AC Voltage is directly under water, corrosion or puncture take place easily, because water is electric conductor, when the electric heating generating means is breakdown, 220 volts of external alternating currents just are sent to human body by the water that flows out, thereby the generation electric shock accidents, the life security that jeopardizes the people; (2) directly profit uses water as heat transfer medium, and heat transfer efficiency and heat-insulating property are poor, and the thermal efficiency is low, the hot water temperature is low, cannot reach customer requirements, and the hot water of being supplied is sometimes cold and sometimes hot, steam flow and temperature all do not reach customer requirements, and power consumption is big, energy consumption height, cost height.

The purpose of this utility model is shortcomings such as prior art is dangerous, the thermal efficiency is low, energy consumption is big, cost height in order to overcome, and a kind of safety, thermal efficiency height, energy consumption is little, cost is low dielectric heat-conducting electric-heating steam, water heater are provided.

The purpose of this utility model can reach by taking following measure: dielectric heat-conducting electric-heating steam, water heater, comprise shell, heat exchanger, electric heater, temperature controller, water inlet pipe, outlet pipe and draw together evaporimeter, its design feature is: heat exchanger comprises the insulation heat transfer medium, canister, canister is littler than shell, be fixed between the inner chamber of inner casing and its outer surface and the outer casing inner wall and leave the gap, the gap is not communicated with the inner chamber of canister, the gap is full of the insulation heat transfer medium, water inlet pipe passes the inner chamber that shell inserts canister, outlet pipe is positioned at the opposite side of canister and enters the inner chamber of canister by evaporimeter, electric heater is soaked in the insulation heat transfer medium and by the insulation heat transfer and gives canister, temperature controller is by temperature detector, warm inductor of oil and computer control are formed, temperature detector is positioned at the surface of shell, and the test side of oily temperature inductor is soaked in the insulation heat transfer medium.

The purpose of this utility model also can reach by taking following measure:

Canister is the big sleeve of copper, cover one copper small sleeve and two sleeves are ring type structure in the big sleeve of this copper, leave the space between big sleeve, the small sleeve, the inner chamber of small sleeve is communicated with the gap, electric heater stretches into the inner chamber of small sleeve from the bottom of shell and is dipped in the insulation heat transfer medium, evaporimeter is a copper vessel, be arranged at the top of small sleeve, the outer surface of evaporimeter is connected outlet pipe with the contact of insulation heat transfer medium, inner chamber and is connected with the space by conduit, the opposite side in space is connected with water inlet pipe, and the top of shell is provided with the heat transfer medium input.

Shell is that stainless steel is made, its outer surface is provided with a protective layer, and the insulation heat transfer medium is No. ten transformer miscellas, and electric heater is the 220V/3KW electrothermal tube.

Compared with prior art, the utlity model has following outstanding effect:

(1) because the electric heater of band High Level AC Voltage only contacts with the insulation heat transfer medium and isolates with water, therefore the water that comes out from delivery port can be not charged, electric shock accidents can not take place, not entail dangers to people's life security; In addition, because the electric heater of band High Level AC Voltage places insulation heat transfer medium (No. ten transformer miscellas), be not easy to take place corrosion or puncture, therefore, the utility model is difficult for producing fault even damage, safety durable because of electric heater punctures.

(2) because insulate heat transfer efficient height, high insulating effect, therefore power consumption is little, thermal efficiency height, the hot water temperature can be according to user's requirement adjustment, reach customer requirements, and the hot water of being supplied maintenance constant temperature, get final product well-off steam by the control inflow, steam flow and temperature all reach customer requirements, and less energy consumption, cost are low.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the structure cut-away view of the utility model embodiment 1.

Fig. 2 is that the A-A of Fig. 1 cuts diagrammatic sketch to structure.

From Fig. 1, Fig. 2 as can be known, present embodiment 1 comprises shell 1, heat exchanger 2, evaporimeter 3, electric heater 5, temperature controller 4, water inlet pipe 12, outlet pipe 13 and heat transfer medium input 15, heat exchanger 2 comprises insulation heat transfer medium 16, canister 8, canister 8 is fixed in the inner chamber of inner casing 1 and leaves gap 11 between its outer surface and shell 1 inwall, gap 11 is obstructed with the inner chamber of canister 8, gap 11 is full of insulation heat transfer medium 16, canister 8 is the big sleeve of copper, cover copper small sleeve 9 in the big sleeve 8 of this copper, and two sleeves are ring type structure, big sleeve 8, leave space 10 between the small sleeve 9, the inner chamber of small sleeve 9 is communicated with gap 11, obstructed with space 10, the inner chamber of small sleeve 9 is full of insulation heat transfer medium 16, electric heater 4 stretches into the inner chamber of small sleeve 9 from the bottom of shell 1 and is dipped in the insulation heat transfer medium 16, evaporimeter 3 is a copper vessel, be arranged at the top of small sleeve 9, the outer surface of evaporimeter 3 contacts with insulation heat transfer medium 16, inner chamber connects outlet pipe 13 and is connected with space 10 by conduit 14, and the opposite side in space 10 is connected with water inlet pipe 12; Water inlet pipe 12 passes the space 10 that shell 1 inserts canister 8 inner chambers, outlet pipe 13 is positioned at the opposite side of canister 8 and enters the opposite side space 10 of canister 8 inner chambers by evaporimeter 3, electric heater 5 is soaked in the insulation heat transfer medium 16 and by the water that stores in insulation heat transfer medium 16 and the canister 8 isolates, temperature controller 4 is made up of temperature detector 6, oily temperature inductor 7 and computer control, temperature detector 6 is positioned at the surface of shell 1, and the test side of oily temperature inductor 7 is dipped in the insulation heat transfer medium 16; Shell 1 is for stainless steel is made, its surface is provided with a protective layer 17, and insulation heat transfer medium 16 is No. ten transformer miscellas, and electric heater 4 is the 220V/3KW electrothermal tube.
