The utility model has the advantages of no water scale on the surface of the heating device, safe and reliable use, no water leakage of the heating inner container, and high heating efficiency.

Description

Electric heater

Technical field

The utility model relates to a kind of electric heater.

Background technology

Existing electric heater comprises shell, heating inner bag, electric heater unit and is located at water inlet pipe and the outlet pipe that heats on the inner bag.During use, heated water enters the heating inner bag from water inlet pipe, and water is heated the back and flows out from outlet pipe.Because the water quality difference of China each place is bigger, electric heater unit service time for a long time after, its surface can form incrustation scale, and along with the prolongation incrustation scale of time can be tied thicker and thicker, the thermal efficiency of electric heater unit can reduce, and the heat transmission speed is slack-off, the heat conduction of heater is not gone out, be easy to cause the explosion on heater surface, produce electric leakage, use dangerous; Some earth leakage protective devices are arranged at present, but they can not fundamentally solve the problem of electric leakage.The water that has also contains the chlorine molecule, and it can corrode the heating inner bag, drainage can occur after the time is long.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of surface of electric heater unit can not produce incrustation scale, and is safe in utilization, reliable, a kind of electric heater that the heating inner bag can not leak.

In order to achieve the above object, the utility model is achieved in that it is a kind of electric heater, comprises shell, heating inner bag and electric heater unit, it is characterized in that: filled pure water in the heating inner bag, electric heater unit is positioned at the heating inner bag; Also comprise insulation outlet pipe, insulation oral siphon that is communicated with the heating inner bag and the heat pipe that is communicated with insulation outlet pipe and insulation oral siphon, heat pipe is snakelike distribution; Also comprise the water pump that is located at the circulation usefulness on insulation oral siphon or the insulation outlet pipe; Also comprise the pipe that is heated that is set in outside the heat pipe, an end that is heated pipe is a water inlet, and the other end is a delivery port.

Also comprise the water storage liner of filling pure water, it is communicated with described insulation oral siphon, and it also is communicated with the heating inner bag by the insulation water pipe.

Also comprise water storage liner, first cross valve and second cross valve of filling pure water; The a end of first cross valve is communicated with the heating water bladder and is positioned at its top, and its b end is communicated with insulation outlet pipe, and its c end is communicated with water storage liner and is positioned at its top, and its d end is communicated with the b end of second cross valve; The a end of second cross valve is communicated with the heating water bladder and is positioned at its underpart, and its c end is communicated with water storage liner and is positioned at its underpart, and its d end is communicated with the insulation oral siphon.

The utility model advantage compared with prior art is that the surface of heater can not produce incrustation scale, and is safe in utilization, reliable, heats inner bag and can not leak thermal efficiency height.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Embodiment one

As shown in Figure 1, it is a kind of electric heater, comprises shell 1, heating inner bag 2 and electric heater unit 3; Filled pure water in the heating inner bag, electric heater unit is positioned at the heating inner bag; Also comprise insulation outlet pipe 8, insulation oral siphon 5 that is communicated with the heating inner bag and the heat pipe 7 that is communicated with insulation outlet pipe and insulation oral siphon, heat pipe is snakelike distribution; Also comprise the water pump 4 that is located at the circulation usefulness on insulation oral siphon or the insulation outlet pipe; Comprise that also being set in outer being heated of heat pipe manages 6, an end that is heated pipe is a water inlet 61, and the other end is a delivery port 62.

During use, connect power supply, electric heater unit heats the water in the heating water bladder 2, under the effect of water pump 4, heated pure water in the heating water bladder flows out behind heat pipe 7 from insulation outlet pipe 8, enter in the heating inner bag from insulation oral siphon 5, this moment, the heat pipe heating flowed into the water that is heated the pipe 6 from water inlet 61 again, and this water flows out from delivery port 62 again.Because when using, electric heater unit does not contact the water that contains medium, so its surface can scaling, drainage can not occur yet.

Embodiment two

As shown in Figure 2, all elements in comprising embodiment one, also comprise the water storage liner 9 of filling pure water, it is communicated with described insulation oral siphon 5, and it also is communicated with heating inner bag 2 by the insulation water pipe.Because water storage liner is arranged, its hot water effluent measures greatly.

Embodiment three

As shown in Figure 3, all elements in comprising embodiment one, also comprise water storage liner 9, first cross valve 10 and second cross valve 11 of filling pure water; The a end of first cross valve is communicated with the heating water bladder and is positioned at its top, and its b end is communicated with insulation outlet pipe 8, and its c end is communicated with water storage liner and is positioned at its top, and its d end is communicated with the b end of second cross valve; The a end of second cross valve is communicated with the heating water bladder and is positioned at its underpart, and its c end is communicated with water storage liner and is positioned at its underpart, and its d end is communicated with insulation oral siphon 5.Because water storage liner, first cross valve 10 and second cross valve 11 arranged, it can circulate to 9 pure water in the water storage liner and preheat, and its hot water effluent measures greatly.
