Abstract
The utility model relates to an electric water heater which is characterized in that the electric water heater uses a positive and a negative annular electrode plates to connect with direct current without a resistance wire so that water flows through between the positive and the negative electrode plates, the water is used as a conductor to form a closedcircuit and also becomes a resistance heating wire having fast heating speed and high heat efficiency. The electric water heater has no scale generation and safe use, and the direct current for the water heater is provided by a control rectifying power supply.
Description
The utility model is about water heater, particularly about electric heater.
The subject matter that at present existing electric heater exists is dangerous, easy electric leakage, the thermal efficiency is low, firing rate is slow, uses heat-generating pipe or heating sector-meeting to produce scale formation for a long time, influences the thermal efficiency, and the scope of application is little etc.
The purpose of this utility model just provides and a kind ofly can overcome not enough and safer reliable that existing product exists, and firing rate is fast, the thermal efficiency is high, and heater does not produce incrustation scale, and the electric heater of certain magnetization is arranged.
This practical technical solution is by last connection cover (1), fountain head (10), shell (9), electric heater unit (4), (5) hot water effluent's switch (11) and control rectification circuit (12) institute, the above-mentioned electric heater unit (4) that is characterised in that of the present utility model, (5) the shellring shape battery lead plate of being manufactured by conductive material is formed, intermediate layer annular electro pole plate (4) connects on the output cathode of control rectification circuit (12), and be fixed on bottom in the last connection cover (1) manufactured by insulating materials, in, outer two-layer annular electro pole plate (5) is connected on the output negative pole of control rectification circuit (1 2), and be fixed on the gripper shoe of manufacturing by insulating materials (6), at the lower limb of positive plate (4) and the top edge of negative plate (5), and be provided with certain water flow space between the positive/negative plate and between the madial wall of pole plate (5) and shell (9), so that current pass through, the top of this external hot-water switch (11) disposes annular magnet (8), make the glassware for drinking water after the heating magnetization be arranged, this electric heater unit (4), (5) direct current that is provided by control rectification circuit (12) is worked.
Safety when characteristics of the present utility model are to use, reliably, no matter any circuit electric current, voltage in " open circuit, short circuit " water occur all within safe range, and not strictly when using require to start to exchange fire line, zero line, ground wire in accordance with regulations, if the unexpected open circuit of ground wire, electric heater work as usual, if the unexpected open circuit of live wire or zero line, electric heater is not worked, is not had hot water, do not have any danger.When the electric heater work done was heated, electric current, voltage were zero in the water.Elder generation's water flowing, back energising when the water yield reaches the running water maximum stream flow, can be in three seconds rise to 65 ℃ with water temperature from 36 ℃, and the thermal efficiency and firing rate are all above existing product.And scaling not.
Below to Brief Description Of Drawings.
Fig. 1 is the structure cutaway view of the utility model electric heater.
Fig. 2 is the circuit diagram of the rectification control section (12) of the utility model electric heater.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
In Fig. 1 by on connection cover (1), shell (9) and fountain head (10) have been formed the external structure of the utility model electric heater, and manufacture by heat-resistant insulation material, the endoporus and the water tap of last connection cover (1) link, cold water enter after with the joining cushion plugs of loam cake (1) (2) buffering after enter the electrical heating district, the annular electro pole plate (4) and (5) that in the electrical heating district, have three floor to make by stainless steel material, battery lead plate (4) links with the output cathode of control rectification circuit (12), in, outer two layers of annular electro pole plate (5) link with circuit (12) output negative pole, bottom in positive plate (4), the top of negative plate (5), and just, the space (direction of the small arrow among Fig. 1 is represented water (flow) direction) that allows current pass through is all arranged between the negative plate and between the madial wall of negative plate (5) and shell (9).Positive plate (4) is fixed on the bottom in the loam cake (1), the top that negative plate (5) is fixed on gripper shoe (6), and be fixed on the cushion plugs (2) by lower shoe (7) and bolt (3), with the relative position between the assurance positive/negative plate and the position of water stream channel, on base plate (7), be connected to ground wire.When cold water enters between the positive and negative annular electro pole plate, K1, K2 power switch among closed Fig. 2, water between positive/negative plate has promptly been connected positive and negative ring plate as the conductor with very big resistance and has been formed the closed-loop path, (annular positive/negative plate (4), (5) do not generate heat), this moment, electric current passed hydrone, make electric energy be converted into heat energy, say that vividerly the water of this moment has then become " resistive heater ", wait similar heater element.Under the effect of water at pressure of heating, flow into this water heater middle part, arriving hot-water switch (11) after the magnetization of magnetic field (8) locates, hot-water switch (11) is to be made by bimetal leaf, the bimetal leaf temperature distortion is opened, is discharged water when water temperature reaches more than 40 ℃, flow out by shower nozzle (10), promptly finish whole heating process.
Shown in Figure 2 is the line map of the utility model electrical heating partial rectification, control circuit (12), be by:
A, control circuit have been formed the basic circuits for triggering of electronics by BTS bidirectional triode thyristor, capacitor C, resistance R diac 2D, resistance R, potentiometer W.Thereby change the W potentiometer and change the purpose that the load both end voltage reaches regulation and control.L is a power supply indicator.BX, BX are molten fracture of wire, and K, K are single-phase two control alternating current input switch.
B, rectification circuit are to adopt integrated circuit ZCK single-phase full wave rectifier bridge, be used to provide one and can keep safe and reliable galvanic current source, can keep the heater self structure that dynamic change continuously takes place again, thereby in time clear up incrustation scale automatically, so that make full use of the energy, the operating efficiency of performance heater.
Regulator potentiometer W changes the load both end voltage, makes the difference of electric flux to the water acting, and also with regard to different 36 ℃-65 ℃, the adjustable on demand water temperature that makes remains within the stable temperature range water temperature that obtains.
Streamflow is then opened the flow to maximum for running water, tap.
Ground wire (0) as protective wire, be safety device.Be with or without electric heater and all can be operated in the safe current range, the electric current during work in the water, voltage are " zero ".
