The types of electric water heater, the water heater

In enclosed more classification method: according to the different methods of water points, namely hot type (fast) electric water heater and water storage type electric water heater can be divided into two by water control way before system in and after the standard electric water heater. Former type electric water heater water temperature and water J8 control mode is to rely on in the cold water inlet side (front) of the cold water valve to control, in the hot water outlet valve is not set. And then type the working situation of the electric water heater is to rely on in the hot water outlet (i.e., the back-end) to control the hot water valve, in the cold water inlet side is not set up the control valve. After class, type electric water heater is easy to install and use the advantages of, is the development direction of electric water heater.

New electricity, water, for example, light electric water heater, it USES the Italian mature technology, form a complete set of temperature controller in France, with American English luo lai cafe low-grade material made of a heating device, the use of microcomputer control system, digital display temperature control. The electric water heater tank adopts a badder-like inner container inside enamel of Italian technology and design and manufacture of key is changed or thickening stainless steel tank plus high temperature coating, in order to increase the tank anticorrosion ability, two bladder can be arbitrary choice. In addition, the use of magnesium anode, can soften the water quality, and can prevent fouling, main corrosion resistance, anti-aging, long service life, etc.

2. I.e. thermal type electric heating water

(1) the basic working principle of the instant water heater

Instant water heater is also known as rapid type, instantaneous, or the current electric water heater, instant water heater, the basic features are: cold water into hot water out, as long as a hot water faucet, a few seconds can be continuously continuous supply of hot water, hot water, turn off the tap.

According to the different heating form, instant water heater can be divided into the following

(1) bare electric wire heating electric water heater;

(2) the electrothermal heating electric water heater;

(3) electric heat pipe heating electric water heater.

Instant water heater heater is located in a wood box, box the groove can't bear too high water pressure, at the same time slot to the left and right side of the pole and the two poles, introduced electric wire, if the water pressure effect HuiJiao damage for a long time, so, instant water heater can't make it after format. Format are made before. In addition, in order to ensure the safe usage of instant water heater, anhydrous dry heating does not occur, at the cold water into] has to flow to move the switch signals of pressure sensor, pressure sensor's ability to move the switch stress of the diaphragm; Purport, and cannot be under pressure for a long time, so instant water heater are generally made before the pattern.

Typical Ip hot water heater mainly 6 AD model plate, pressure sensor, power regulator, adjustive bibcock, inlet pipe and outlet pipe parts, etc, which is instant water heater heating trough plates close Man components, its structure diagram as shown in figure 1, the trough plate, seal field, cover, and an electric heating element, the electric heating element, the wipe trough plate.

Instant water heater direct conduction heating mode is adopted to work, because the electric heating element in the groove of the slot pull, so when cold water flows through make can be directly through the electric heating element and the heated surface. And because the sink like a snake, so water inlet gradually sink into the cold water is heated, can get higher temperature at the outlet of hot water.

(2) instant water heater circuit principle

I.e. thermal type electric drum water implement principle of the circuit shown in figure 2, micro switch YK is normally open contact switch, it is controlled by the pressure sensor. When the water heater beads; Before turn on the water, because of no water pressure. Pressure sensor signal, YK not action, relay bei thread not suck, the main loop of the power supply. After the open water yan, subjected to hydrostatic pressure sensor signal that YK actions, Yang and JD line, JDl, melamine switch, power supply circuit through. Indicator lh-zd on, the heater (electric heating element) DR electricity work, water flows within the bn thermal dampers are heated.

Power conversion 7: shut (power regulator) TK points 4 block: namely the power o, power power power of 1, 2, 3. Through the adjustment of the power switch, can make several groups of electric heating element change connection methods, through the electric heating element of different medium, in parallel connection, in order to achieve different power combination, resulting in different temperature of hot water. People can according to need to adjust the cold water into the water, hot water respectively, to control and adjust the water sink.

5 e pressure sensor's role is to ensure that only in the water and under the condition of a certain pressure, the circuit to turn on the heating work,

You can avoid the phenomenon of electric heating element anhydrous dry.
