The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises water receptacle 3, is arranged in water receptacle 3 and heating unit, detecting signal unit 5, controller 4 that its water is heated and the heated condition indicating member of being controlled by controller 47.
Described heating unit comprises the heat conduction casing 2 that an inside is equipped with conduction oil and is made by Heat Conduction Material, and the interior electrothermal tube 1 of institute's conduction oil of adorning in the whole heat conduction casing 2 that submerges.
Described detecting signal unit 5 comprises temperature sensor one 5-1 that in real time water temperature in the water receptacle 3 is detected, and described temperature sensor one 5-1 connects controller 4.Described controller 4 is tackled electromagnetic switch one 6-1 that is serially connected in electrothermal tube 1 heating circuit mutually and is carried out break-make control according to the real-time institute of temperature sensor one 5-1 detected temperatures signal.
In the present embodiment, described detecting signal unit 5 also comprises level sensor 5-2 and real-time temperature sensor two 5-3 that the oily temperature of the conduction oils of adorning in the heat conduction casing 2 is detected that in real time water level in the water receptacle 3 detected, described level sensor 5-2 and temperature sensor two 5-3 all connect controller 4. simultaneously, after comprising that also the alarm indicating member 4 couples of level sensor 5-2 of 8. described controllers that controlled by controller 4 and temperature sensor two 5-3 institute detection signal carry out analyzing and processing, electromagnetic switch two 6-2 that are serially connected in electrothermal tube 1 current supply circuit of reply carry out break-make control mutually; And reply alarm indicating member 8 is controlled mutually. described temperature sensor one 5-1 is installed on the lower sides of water receptacle 3, and temperature sensor two 5-3 are installed on the upper portion side wall of heat conduction casing 2.
Described heat conduction casing 2 is one to have pouring orifice and wiring hole, and the airtight casing that seals by end cap 2-2.The shape of described heat conduction casing 2 is specially cylinder or multiedge cylinder, in the practice, can heat conduction casing 2 be made as the casing of other Any shape according to the actual requirements.In the present embodiment, the outer end of described airtight casing is fixed on the sidewall of water receptacle 3.Described heat conduction casing 2 is a metal cabinet.The concrete level of described temperature sensor two 5-3 is installed in end cap 2-2 inside upper part.
Use before above-mentioned electric water heater heater heats the water in the water receptacle 3, in the temperature value that need heat by the water in 4 pairs of water receptacles of controller 3, the heat conduction casing 2 in the oily temperature upper limit of conduction oils and the water receptacle 3 the water level lower limits set.When using above-mentioned electric water heater heater that the water in the water receptacle 3 is heated, at first, connect the power supply of electrothermal tube 1 again with after filling with water in the water receptacle 3; Make electrothermal tube 1 continue heating to the conduction oil in the heat conduction casing 2 earlier, by the heat exchange between heated conduction oil and the heat conduction casing 2 outside all side water water in the water receptacle 3 is continued heating again, until all being heated to the water in the water receptacle 3 temperature required.In addition, be noted that: in the heating process, should guarantee that the conduction oil that the water in the water receptacle 3 can not enter in heat conduction casing 2 inside and the heat conduction casing 2 can not enter in the water receptacle 3.
