The utility model makes use of the electrical energy to generate an alternating electric field between the cover-shaped electrode and the core electrode, the flowing water molecules are excited to collide mutually, and the heat is self-generated to achieve the goal of heating water. Because of the ingenious design, the utility model has the advantages of small size, convenient usage and regulation, low energy consumption, etc.

Description

Electric water heater

The utility model relates to a kind of electric heater, and it belongs to the electric calorifie installation class by electric field, magnetic field or electromagnetic field heating.

Popular water heater has three major types at present, and the one, gas heater, the 2nd, coal burning water heater is a coal-burning boiler.The 3rd, resistance wire formula water heater.The advantage of first kind water heater is that hot water temperature and flow can arbitrarily be adjusted, and is easy-to-use, but heating efficiency is limited and utilization rate of heat value is not high; Though the second class water heater is economical, the one-time investment of equipment needs the personal management greatly again, and also troubling to the pollution of atmosphere; Although the 3rd class water heater is convenient and practical, very easily damage.

The purpose of this utility model, advantage such as being provides a kind of novel electric heater to society, and it has convenient and practical, small and exquisite and the rate of heat addition is high, the calorific value loss is little is enough to overcome the weak point of existing water heater.

Electric heater of the present utility model contains hood-like electrode 1, core electrode 2, water nozzle seat 3, plunger 4, plunger guide cover 5, adjusting screw(rod) 6, handwheel 7 and end cap 8, its technical characterictic is that described hood-like electrode 1 is the thin-walled goblet made from conductive material, the suitable location in its top and skirt section offers a plurality of water flowings duct 101,102, and its outside, skirt section forms with hood-like electrode terminal 19 by lead 22 and is electrically connected; Described core electrode 2 also is the thin-walled goblet made from conductive material, and it is fitted in the head of plunger 4; Described water nozzle seat 3 is a cylindrical body, with hood-like electrode 1 coaxial assembling, respectively has screw at its top and waist, and the screw of waist is installed water nozzle 10, and the screw at top is installed water nozzle 11; Described plunger 4 is a cylindrical body, it leaves the space coaxial assembling in ground each other with above-mentioned hood-like electrode 1 and part is placed oneself in the midst of within the coaxial plunger guide cover 5, establish contact screw 18 at the plunger head center, this screw 18 makes core electrode 2 form with core electrode electricity-linkingup point 20 by flexible wire 21 and is electrically connected, between plunger 4 skirt sections and described plunger guide cover 5, on the branch, have O-

ring seals

13,14, can order about it and overlap 5 inwalls along plunger guide and do and be connected with in plunger 4 lower end central authorities, lower slider, include drive screw 6, handwheel 7 is in interior manual adjustment means; Orchid is managed in described plunger guide cover 5 its upper ends, two circle boss are established in the flange upper surface, outside rectangular section boss 51 is used to clamp above-mentioned water nozzle seat 3, and be provided with O-ring seals 12 between rectangular cross section boss 51 outside roots and the described

water nozzle seat

3,52 lower edges of inside arc profile of tooth section boss in order at interval hood-like electrode 1 and core electrode 2; Described end cap 8 overlaps 5 coaxial assemblings with above-mentioned plunger guide, and between the lower surface of the interior step surface of end cap 8 and above-mentioned plunger guide cover 5, is laid with the packing ring 9 that conductive material is made.

The utility model is described in further detail below with reference to accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

Among the figure, 1 hood-like electrode, 2 core electrode, 3 water nozzle seats, 4 plungers, 5 plunger guide covers, 6 adjusting screw(rod)s, 7 handwheels, 8 end caps, 9 packing rings, 10,11 water nozzles, 12,13,14O shape sealing ring, 15 pads, 16 snap rings, 17 handwheel locking nuts, 18 contact screws, 19 hood-like electrode terminals, 20 core electrode electricity-linkingup points, 21 flexible wires, 22 leads, 51 rectangular cross section boss, 52 curved tooth shape section boss, 101,102 water flowing ducts.

When connecting water sources (for example running water) with water nozzle 10, current will enter the space that hood-like electrode 1, core electrode 2 surround through the water flowing duct 102 in hood-like electrode 1 skirt section, be full of this space after, again by water flowing duct 101, water nozzle 11 outflows.At this moment, if apply an alternating voltage (for example 220 volts of alternating currents) at hood-

like electrode terminal

19 and 20 of core electrode electricity-linkingup points, then can between hood-like electrode 1 and core electrode 2, form an alternating electric field, this electric field can make the hydrone of interpolar be excited and mutually collision, spontaneous heat and reach heated purpose.Driving plunger 4 with handwheel 7 again makes it along the upper and lower slip of inwall of plunger guide cover 5, to change the axial clearance between hood-like electrode 1 and the core electrode 2, can bring variation to electric-field intensity again,, therefore water temperature played the effect that convenience is regulated so the heated speed of water can be different.Not the time spent, cut off the electricity supply, close the water source and get final product.

In sum, convenient and practical, advantages such as volume is small and exquisite and the rate of heat addition is high, consuming little energy that the utility model has really are worth promoting.

The utility model also can be used for the laboratory, as the usefulness of the evaporimeter of producing distilled water, as long as flow of inlet water is controlled at below the limit, just can make water reach the purpose of gasification.
