Working Principle Analysis of Steam Electric Ironing Machine

Date of release:2019-05-28 Author: Click:

Steam electric ironing machine is safe and convenient to use, but because most of the instructions do not include circuit diagrams, once damaged, it will bring inconvenience to maintenance. Now there are many types and specifications of various electric ironing machines on the market, but the principle of circuit operation is basically the same. This paper takes one of them as an example, draws circuit diagrams and briefly describes its operating principle.

Operating Principle

220V City Electric Power Supply Control Circuit and Relay K1.S1 are power switches of electric heating circuit. S2 is mercury switch. When the top cover of iron is raised, S2 closes. IC1_pin outputs high level, and triode VT1 is fully conductive. The output voltage of 220V City Electric Power Supply Control Circuit and Relay K1.S1 are + 12V DC voltage after regulated by resistor R1, R3 and capacitor C1, rectifier bridge UR rectifier, capacitor C2 filter and regulator diode VD1.

Relay K1 is sucked in, contacts K1-1 are usually opened, heating wires EH1 and EH2 are electrically heated, and iron temperature rises above the set temperature. Thermal maintenance elements FR (also used as temperature control devices) connected in series in the circuit of electric heating wires are disconnected, EH1 and EH2 stop heating. When the temperature drops below the set value, FR is connected again. Rehabilitation heating of electric heating wires is used to keep the iron temperature basically stable and ironing clothes, iron. The top cover moves downward and the mercury switch S2 is disconnected. After about 30 seconds, the output of IC1_foot is low. The transistor VT1 is cut off, the relay K1 is out of power, the contact K1-1 is often disconnected, and the heating of EH1 and EH2 is stopped. It is guaranteed that the ironed clothes will not be ironed. If the ironing temperature falls again at this moment, the top cover of the ironing iron will be lifted when the ironing demand is unsatisfactory. If the temperature is unsatisfactory, the circuit will recover to the heating condition and continue to heat the ironing.

As an ironing equipment, desktop windmill includes four parts: base, extrusion arm, press plate and cushion plate. It is mainly used in households, laundries, clothing stores and garment factories. The ironing board area of the desktop ironing machine is several times larger than that of the ordinary electric ironing machine, which saves more than half the ironing time. Moreover, the ironing board of the desktop ironing machine has a wide range of temperature conditioning. The steam generator directly vaporizes the ironing board with water, which is suitable for ironing all kinds of fabrics. The strong steam makes the stubborn folds disappear immediately, and the ironing wool, velvet and silk clothes cannot afford to be ironed. Smooth surface, desktop

About IOO pounds of active pressure will occur after the pressing plate of the ironing machine is pressed down. It does not need to be forced like an electric iron.

Press and ironing clothes, so it is labor-saving, in addition, the desktop ironing machine also has an active shutdown insurance file, easy to operate and safe.

Nowadays, all the ironing boards of electric ironing machines produced at home and abroad are made by the following processes-

The aluminium alloy plate of type 3003 is used for stretching forming by hydraulic press after tapping. The screw and nut are welded on the inner and outer surfaces of Guangdong electric ironing machine by bump welding method. After electrochemical spraying treatment, the heating pipe and other fittings are installed on the inner and outer surfaces.

Provide electric ironing machine

The ironing board made of this material and technology has the following shortcomings-

1. Type 3003 alloy aluminium sheet has large internal stress. After stretching, the whole pressing surface is not even. The roughness of the ironing machine is generally more than 2 mm, and the circumference is upward, which causes the ironing clothes to touch.

Non-uniform surface touch, when the whole pressing plate is heated, it is easy to deform, making the whole pressing surface more uneven.

2. There are some faults in the screw welded on the inner and outer surfaces of the ironing plate, especially when the screw is heated and dilated, it is difficult to fix because of the large force and simple loosening of the screw.

3. The inner and outer surfaces of the ironing board are directly fitted with the heat pipe, and the heat transfer surface touched by the heat pipe is only one, so the heating effect is not ambitious.

4. The working procedure is tedious and time-consuming.
