2.INTRODUCTION OF PRODUCTS

P.06

2.1 haracteristics of product

It is the latest designed machine, which have many advantages such as fashion, large

rated washing capacity and large washing range. Specifically, its feature is as following:

1.Large washing range from cotton to wool and silk.

2.Gentle washing: no twist and little abrasion.

3.Electron auto-balance system, that is, the PCB panel controls the speed of spin and

ensures uniform distribution of clothes to reduce the wear of textile caused by its

vibration.

4.The drum of this machine is made of stainless steel of high quality and the cabinet is

durable.

5.The maximum temperature of washing water could be controlled independently and it

is up to 90℃.

6.Unique washing methods: rain, soak, throwing-knocking knead and so on, which can

wash clothes uniformly and improve washing performance.

7.Safety guard: water level control, door lock, child lock etc.

8.Anti-crease function: there is an automatic anti-crease and soak function in the

synthetic program, that’s, it doesn't drain at the end of washing and leave the clean

textile in the water of the drum to achieve the function of less crease.

9.Function of adjusting spin speed : select different spin speed according to textile.

10.Electronic water distribution system: The machine uses PCB to control the inlet valve

and distribute water properly at the different stages and dissolve detergent and softener

absolutely to improve washing performance.

2.2.Working principle

Drum washing machine wash clothes mainly in virtue of mechanical friction, chemical

force and temperature force. When the machine works, the motor runs clockwise several

seconds and runs anti-clockwise several seconds to drive the drum whose three lifters

hold up the clothes pressing against the inside of the drum. When clothes rise close to the

top, because the speed of motor is low and the centrifugal force is not enough to overcome

the gravity, clothes fall and impinge with washing liquid (like manual throwing-knocking

washing). The second force is the extrusion force of clothes (like manual extrusion). The

last force is the friction between clothes, clothes and lifters(like manual knead). To

improve washing performance, automatic drum washing machine could automatically

heat the washing liquid, whose temperature can be adjusted from 30℃ to 90℃. The high

temperature quickens the movement of the numerator of the washing liquid and speedups

the Chemical reaction. In a word, drum washing machine destroys bonding force between

dirt and clothes in virtue of intergraded force of water, detergent and mechanical force, to

clean away the dust.

When clothes raised close to the top, centrifugal force is not enough to overcome gravity, and therefore clothes fall and impinge washing liquid to improve washing performance. Spider kit The spider is the aluminum die-casting. There is a bushing in the axis which is to reduce the wear and tear of V-shaped edge of the oil seal. When installed bushings, the powder-like debris produced by it cut shaft bushings should be removed, or they will wear oil seal. To avoid wear and tear, grease should be applied the corresponding position of the oil seal to ensure that it will play in the role of lubrication in the whole life of washing machine and not dry or off. Spider kit is fastened on the drum with three stainless steel bolts.

4.10 Inlet hose

Inlet hose connects household tap and washing machine. The pipe of inlet hose has a high-pressure capacity which nets the high strength polyester

fiber lines. Generally, household water pressure is less than 1MPa, and practically the water pipes of Midea washing machine could stand the pressure of 2MPa in one minute not dehiscence, not deformation, and bearing 4MPa pressure not burst. As for inlet hose, there are many performance requirements such as hot and cold alternate anti-shocking, anti-bending etc.

4.11.1 Pressure switch Working principle Mechanical pressure switch have two main components that is balloon and electrical structure. The balloon is fastened sealedly on the pressure switch with hose clamp and the end of balloon is connected on the bottom of tub using press chamber, plastic pipe. During flowing water, the bottom of tub is firstly submerged and its space linking the balloon is closed. With the increase of water level and the pressure of closed air increase gradually until push the needle of rubber membrane. Another parts is the electrical structure. With the balloon inflating, a needle top spring chip to make it conduction and then change the current direction. Usually, the fault of pressure switch is leakage and contact barrier. It is easy to check them. Huff the inlet inflatable with your mouth, and you can clearly hear the clatter sound of spring chip clicks, if it is multi-level control, several clatters sound can be heard. There is a group of plastic crosser screw in the side nearly line. These screws are used to control the height of water level (to avoid adjust it, there is a certain color lacquer to sign). Pressure switch is a very important part in the washing machine, which is not only control water level but also influence the safety of washing machine. Once it is invalid, water level can’’t be controlled. Low-frequency analog electronic pressure switch: its main principle is a group of LC oscillation circuit, the change of balloon changes the frequency of LC circuit. Pressure switch feedback to the PCB signal, and PCB issued in accordance with the conditions set to decide water level. The price of low-frequency analog electronic pressure switch is high and as a result its application rares. In a word, pressure switch employs its closed gas room as the basic condition of normal work. And if the gas room is damaged, the pressure switch will be invalid. In addition, pressure switch is the key part controlling heating circuit.

4.11.2 Inlet valve Working principle of inlet valve Inlet valve has two main components: One is the 220V winding which Set in the injection molding nylon colophony Pa66 outside cylindrical cavity and there is an iron core inside of cavity. And normally, iron core is not in the center of cavity due to the spring force. Once power supplys, the magnetic field produced by winding generate force overcoming the spring force to drive iron core, which open the hole of releasing pressure in the inlet valve. The other is the channel part. There is a hole between inlet and outlet that control flux. The default of the hole is closed and controlled by the hole of releasing pressure in the inlet valve. As a result, the fluxing hole can be opened on the condition of power supply, iron core moving and the hole of releasing pressure. In a word, inlet valve works in the condition of power supply and water pressure. Characteristics of inlet valve:

1.Flux: the flux of inlet valve is different by different manufacturer produced. And the flux value usual is from 8L/min to 12L/min (the flux value of this machine is 9.5L/min).

2. Modality: the inlet valve is common single-head valve for the atmosphere can be programmed for mechanical models, the direction of water flow when a cam driven by program - controlled link, Plectrum agencies to achieve watershed; The second category is double-head valve, which is used in electronic-type program - controlled washing machine, and usually water influent from the “pre-wash”box, and the other washing box is the main box, and when the two valve boxes at the same time electricity, water influent from the rinse box, its on / off is control by PCB panel. The last category is three-head valve, which is used in electronic device programmed with the function of drying washing machine, two of grids have the same functions as well followed. And the third one is used to control condensed water, which has small flow.

3.Resistance: the resistance of single-head valve is about 4000Ω。

4.Power value: the power value of single-head valve is about 5W.

4.11.3 Detergent box kit Detergent box kit is made up of detergent box, Detergent box-up and Detergent box-middle. At first, Detergent box-up and Detergent box-middle are pieces of plastic absolute. They are connected and produce many flume as the channel of water flow to weep away the detergent in the box. In order to achieve European standards, an overflow mouth is designed in the detergent box to prevent washing water inflowing the family water system caused pollution.

4.11 Drain system

4.12.1 Drainage system The material of drain hose is Ethylene-Propylene Diene Monomer (EPDM), whose rigidity is 50sha, default thickness is 2.5mm. The drain hose has anti-loosen structure and it ensure there is no leakage during work.

4.OVERVIEW OF MAIN COMPONENTS

P.28

4.12.2 Drain pump As for the up-drainage washing machine, the drum washing machine need drain pump to provide the force. The drain pump head is generally 1~1.5m, tonnage is 24L/min. Drain pump is made up of motor, body, impeller, blower fans. Impeller is derived by the motor to run and drain; the blower fans disperse the heat produced by motor.

In principle, the drain pump has two categories of permanent-magnet pump and cover pole pump.

And drum washing machine usually use the permanent-magnet pump now. The permanent-magnet pump uses the permanent-magnet motor and its winding resistance DC is about 170Ω. And its resistance usually can be measured by millimeters. If resistance infinite, it can be concluded its opening. Actually, the common faults of drain pump was mainly that impeller broken flannel or a hard object jammed or the hard object interrupted by the impeller, and this will cause drain pump can not work. the drainage pump will issued swoosh at the end of draining due to the some water can not be completely discharged from the machine, it is a normal phenomenon. Due to the internal structure of a cavity, filter components upper and lower body by ultrasonic welding. The filter kit main role is Filtering out clastic produced by washing. If don’t clean it timely, it will cause many fault such as pipe plug, Drainage difficulties. Filters should be washed once a month generally. Remove it before draining water and

then put a basin to avoid the remaining water flowing on the floor. Mold cleaning filters carved steps and attention to the

matter in the back of the trap door. During installing it again, the filter should be tightened, otherwise easy leakage.

4.13 Door kit

Door kit is made up of outer door, inner door, door glass, door handle, door hook, door hook spring, hook pin, hinge, hinge cap and screw. The material of outer door is Acrylonitrile Butadiene Styrene (ABS) which have the good anti-aging and anti- ultraviolet properties, and it is elegant generous. The material of inner door is the improved PP material. Door glass is not only good high temperature and impact resistance properties of hot and cold, but also a high intensity.

Door handle is embedded or external. When open the door without loosening after assembled door handle, door hook, door hook spring, hook pin.

4.OVERVIEW OF MAIN COMPONENTS

The material of door hook is zinc alloy. As well hinge, the material of the hinge cap is POM, and the cap set in the pins of hinge ends. The door lock control the door after installing it correctly, the clasp of door lock enter the mouth of the plate front and then they are fixed with screw to avoid scratch between the door hook and the cabinet. After power supply, door hook will be locked and the door can’t be opened.

4.14 Gasket

Gasket is injected molding with EPDM which has many properties such as the high temperature, corrosion resistance, anti-aging. The gasket of Midea washing machine has processed using advanced technique and it has very well performance and beautiful color. What is more, gasket achieves the goal of flexible connectivity between cabinet and tub.

4.15 Door lock

Door lock is the device that is self- locking during electricity and feedback signal to the PCB panel. Delay function: the door can be opened after the unit is off in two minutes.

4.16 NTC temperature sensor

NTC can detect the temperature range from -5℃ to 103℃. The heating function stops in the condition of fault (open or short circuit). Change the NTC before loose the crimpling device.

4.17 Heater

The body of heater is the heating pipe of stainless steel, and its insulation is magnesium oxide powder and the core is the heating filament. The airproof of heater is EPDM which has many properties such as the high temperature, corrosion resistance, anti-aging. The stainless steel heating pipe is welded using sub-arc welding and Seamless Detection. And then intercept set length to install the heating filament and fill magnesium oxide powder, and then tamped through vibration. Finally, a diameter of 12mm heating pipe compressed into 8mm with horizontal compression technology, and that is strictly ensure the full magnesium oxide powder tamped and the quality of welds.The heater is fastened on the tub with bolt. Electrical principle: Heater uses power of 220V voltage and 50Hz frequency. Due to the rated current is less than 10A, the most power of washing machine is less than 2200 watts. Reducing the other

power, the most power of heating at 90℃ is in the range from 1800 watts to 2000 watts and 1000 watts at 60℃. The heater can't heat without water, so firstly the heating function will start only user selects the heating procedure, and secondly heating function is in some special procedure to avoid unreasonable heating, and thirdly when water level is up to the set level, its function will operate. In addition, there is the melting device in the heater, and when the temperature is up to set value(usual setting 160℃), Fuse is fused and cut off power supply.

4.18 Filter

The power change of drum washing machine is in the scope and larger, and in order to prevent its interference on the other household appliance and interfered by the other large appliance, the filter is installed in the washing machine by CCC certification requirements. Filter is made up of a group of capacitance (usually three), a group of inductance and a resistor. In the power supply circuit, it can inhale the high-order harmonic from washing machine and earth. The interference is from the high-order harmonic from the power changes of washing machine as well as the disorders and alternating magnetic field according to the continuous changes of the current in the power cord. The frequency and magnitude of change of its power is in the scope and larger that is from zero watts at soak to hundreds of watts at wash, rinse and spin, to nearly 2000 watts at wash with heating. This change more easily aroused the obvious voltage fluctuations in the domestic circuit which effects the normal use of other electrical appliance. These filters can filter out high-order harmonic and earth. EMC stressed interference and anti-interference, and as for washing machine, it is important to reduce interference to others due to it has good anti-interference.The washing machine use alternating current that can pass capacitor, and in practically, filter will have a very small leakage current (generally less than 2mA). Good grounding is the guarantee of the safe using this machine. And as a result, we particularly stress the importance of grounding. Sometimes, there is an anesthesia in the working machine, please check their grounding device firstly.

4.19 Motor

1. Summary of motor As the driving components, motor drive the drum during washing and spin. Currently, the motor of drum washing machine usually have two-speed motor and series motor.

1) two-speed motor is the running capacitance of single-phase AC asynchronous motor. Stator of the three-phase AC motor embedded in the three-phase windings 120°. If it has symmetrical in the three-phase windings, it can produce rotating magnetic field. Due to using single-phase power, the stator windings of washing machine in the single-phase AC electromagnetic field generate field is a pulsating magnetic field. And this pulsating magnetic field can be divided into two a rotating magnetic field, and their speed equal to the opposite direction. And therefore, their synthetic torque is zero and motor can't be activated except issuing electromagnetic buzzing sound. To start motor, washing machine motor normally uses two measures: First, put embedded in the trough of stator two windings, the main windings (running winding) and the vice winding (start winding), and two windings around axes in space in a 90° angle. Secondly, put a capacitor in series on the winding and therefore the same currents have different phase difference on the two winding. As a result, the vice windings has leading 90° current to the main windings , and make the condition of starting motor. The space between stator and rotor is air gap. Motor has two ways of cooling, natural cooling and fan cooling (air-cool or self-fan cool).

2). Series motor General speaking, series motor is a DC motor. Its highest speed can be up to 20000r/min. Performance characteristic: Its electrical characteristic is hard, the size of it output torque is not effect on the change of voltage. Its has large range of regulating speed and has relatively high efficiency which value is up to 0.2 at the speed of 700r/min and 0.63 at the spinning. Work principle: There are two series ways between exciter stator windings and the armature windings. The one is that the armature windings series two exciter windings in the figure A; and the other one is that two exciter windings series before they series the armature windings in the figure B. And practically, the first way is used more.

The structure of single-phase series motor decides it can use not only alternating current

but also DC. To predigest its circuit and reduce cost of this machine, it is usually to use AC practically. Between the exciter windings and the armature windings are in series one single-phase power supply. When it is in a positive and negative half-cycle AC, the current passing the exciter windings and the armature windings are shown in the figure C and D separately. In a word, the revolve direction of series motor which is used to AC power supply has nothing to the power supply.

Change the shift of single-phase series motor before change the series polity of the exciter windings and the armature windings, and show in the figure E. Series motor usually changes voltage to adjust its rotate speed and the calculating formula of its rotate speed is following: (r/min) E------inductive-voltage of the armature windings a------the number of shunt-wound pairs of the armature windings P------the number of magnetic polity average flux of magnetic polity N------the number of windings of armature windings From the followed formula, if you change the structure parameter (P, N, a) of single-phase series motor, and you can change its rotate speed. But as for the typed series motor, you can change E and by adjusting the voltage value of the motor to change its rotate speed. For drum washing machine, modulate the voltage using the electronic actiyator or the PCB panel to adjust its rotate speed.

2. Main parts and structure of motor Stator and rotor Stator has rotating magnetic field, including stator windings, the core and upper/lower cover for fixing it. Stator windings is the high strength polyester enameled wire enwinding the core which is sheeted with the silicon steel about 0.5mm thickness by riveting and welding. Both sides of the silicon steel are coated with insulating paint, as well as rotor. As the rotating parts, rotor output torque from its shaft, including the rotor windings, core and axial. There is a belt pulley of the motor to output torque on the extended-rotor shaft. Gas gap The unilateral width of the gas gap between stator core and rotor core usually is 0.3mm.

Due to the magnetic resistance of air is less than metal’s, gas cap is larger, the more is magnetic resistance and the more is Exciting Current to produce the same size rotating magnetic field, as a result, power factor of the motor become lower. To reduce the exciting current, the gas gap should become small, taking into account safety factors of assembly and transport. Thermal protector Usually use restorable double foils to cut off the power when the temperature of motor more than the set one, to protect motor, the set temperature of foils is115±5℃, the contractor will restart the power supply when the temperature is lower than the set one.

4.20 PCB panel

General characteristic

1)The control panel executes the main functions below:

2)Control the spinning(high-speed or low-speed spin and the speed of the last spin)

3)Control the temperature of washing liquid

4)Control and adjust the unbalanced load during spin

The control of spinning speed The control panel modulates motor’s speed by modulating its voltage. By modulating the knob position of speed chooser, the user can set the speed value in the control panel. Then comparing the value of the speed and the impulse value from testing motor, when the control panel makes sure that the motor speed arrive the set speed, it will not modulate the voltage of motor. As a result, the washing machine’s drum runs at the set speed.

The control of temperature of washing and heating The user sets the temperature in the control panel by pressing the temperature key; the control panel compares the set temperature and the washing temperature from the

P.34

temperature-testing resist value; when the control panel makes sure that the water temperature arrives the set temperature, it cuts off the heater and stop heating.

The control of unbalanced load during spinning When the washing machine is running the spinning program, if the clothes in the drum are put unbalanced or gravely out of center, the washing machine will vibrate greatly, so the control panel needs to adjust it. The detailed process is as below: when the washing machine is running the spinning, the drum rotating speed will promote from low to high; when it gets to 95r/min ,according to the principal that different eccentric clothes have different rotating speed between ascending and descending, the control panel first checks the testing motor’s rotating speed difference at 95rpm, after a special computing, estimates whether the clothes in the drum balanced, such as balanced distribution. If balanced, the washing machine will run at normal spinning speed until the set highest rotating speed. If unbalanced, after the control panel cutting off the controlling motor 5 seconds, the drum runs 30 seconds at washing speed. It shakes the clothes, tests and computes the motor's rotating speed , and estimates whether the distribution balanced. This procedure runs 12 times until the clothes balanced to spin. If the eccentricity is still large after 12 modulations, it will display UE urgent. Now turn off the machine, open the machine door to replace the clothes or put more clothes to descend the eccentricity, and then choose the spinning program again. NOTE: usually, a towel, jeans and some fabrics have large eccentricity and suggest that

consumers should put 2~3 or more to wash.

6.4 Electrical parts working & testing principle

1. Inlet valve Working principles: A piece of iron core blocks in the inlet valve, and one side of the iron core is the push exerted by spring. When the power is turned on, the winding in the valve will generate a force to pull the iron core up, and then the inlet passage is smooth and the water flow in the drum under the household water pressure . Technique datas: Maximum input voltage: 220-240V Frequency: 50/60Hz Resistance: 4.13K ±10% Flux: 8L/min ±15% Water pressure: 0.2-10bar Temperature of hot water: Maximum 25℃ The testing methods of inlet valve is as follows:

1) Use the multimeter to test the electromagnetism valve resistance, which should be 4.13k ±10%. If the value is infinite or approaching to zero, the valve is invalid and can't let water enter.

2) Connect the inlet valve and tap, if water flows out of the outlet without power being off, the iron core is invalid and should be replaced.

6.TROUBLESHOOTING

P.49

2. Pressure switch Pressure switch, which use the water pressure to control its spring, connects different control circuit through contacting different contractor. Pressure switch has two groups of pressure control point: point 1 connects point 2 in normal state without water, when the water level is up to a certain value, point 3 connects point 1 under the water pressure, providing power to the heater through point 3 and making signal of the water level to the control panel. When the water level is too high, points 1 connects drain pump directly through point 6 and then feedback the signal of overflow to the PCB panel. Technical parameters:

1) Main touch point subsection capacity: Point 3: 16(4) A/250V on/off Point 2: 10(2.5)A/250V on/off

2) Overflow protection point subsection capacity: 1A/250V on/off The test methods of water level switch:

1) In normal state without water, points 1 and 2 connect and points 1 and 3 disconnect, if points 1 and 3 connect without water, the water is not in and appear interference malfunction, it should be replaced.

2) Huff the switch and if it leaks breath, the inlet will be endless. It should be replaced.

3) When the water pressure reach 98mm of water column, points 1 and 3 connect. If not connected, it may appear the malfunction of endless inlet.

3. Door switch Function: There are three connection in the door lock, 1 and 3 provide 220V voltage to the PTC, when the door is close and power is on, PTC will be distortional, then push the middle spring, the points 2 and 3 connect with spring provide power to the peripheral load (motor, pressure switch etc). Meanwhile the plastic bolt in the peripheral spring will insert into the door lock channel outside and Only when the power is off about 2 minutes, PTC will get back. At this time the door can be open. Technical rated: 120V/240V, 16A, PTC Input voltage: 253VAC Rated current: 50mA Start-up current: The testing methods of door lock are as follows:

1) The contractor 2 and 3 are disconnection when the door lock is off (if not, the door lock should be replaced). Supply power to the contractor 1 and 3 (220VAC) 10s, and then turn off, the contractor 2 and 3 will be connection in 30 s, if not, the door will not be locked and should be replaced. Supply power (220VAC) to the contractor 1 and 3 10 s and then turn off, if the contractor 2 and 3 are connection, the door lock should be replaced.

4. NTC and heater The normal working range of NTC is -7℃ to 105℃. The higher of the temperature, the lower the NTC’s resistance value. While the heating temperature will be tested through testing the NTC’s resistance value. NTC is inserted in the resistance’s flange, which seal ring guarantee the airproof quality. You should loosen the lock facility in order to replace the NTC. NTC parameters: R/t speciality: ℃

Resistance speciality:

Temperature range: -7℃-105℃ Resolution: ≤1k Tolerance: ±2.5℃ Test condition: Heater parameters

Voltage: UN±1% Rating power: 1800W Rating voltage: 230VAC Power tolerance: +5% -10% Resistance: About 300

: NTC’s resistance value is 2815 ±3.5% at 25℃,

t is about 27 ,

5. Drain pump When the power is on, it will drain water with its impeller. Technical parameters: Voltage: 220V Frequency: 50 Hz Power: ＜40 W Capacity extent: 1 m Flux: 13L/min The methods of testing drain pump:

1) It's resistance value is about 240 tested by multimeter, if the value is zero or infinity, it need to be replaced.

2003,Tn=60 ,

dRn=2% and dB= 1%

R(25) = 4.828 kΩ± 3.5 %，

R(100)= 330Ω ± 3.3 %

Resistance is made up of two heat fuses which can’t be replaced and integrative (the

insurance facility preventing heating without water)

The testing methods of NTC are as follows: Ω

if its value is zero or infinity, the NTC is fault and should be replaced.

The testing method of heater is as follows: he resistance value of heater Ω

if its value is infinity, the heater is fault and should be replaced.

2) Take off the filter cover and check whether the impeller is blocked, clean up it and then assemble it.

6. Filter In order to decrease the inter-interference between the washing machine and the power grid, L2 and the power grid’s L connector, N4 and the power grid’s n connector, U1 and washing machine’s L connector, U3 and washing machine’s N connector. Filter parameters as follows:

0.68M +2×1mH+0.47μF+2×0.1 F

7. Series motor The motor’s rotate is controlled by SCR, the bigger of the through angle is the higher of its voltage and motor’s speed are, or else, diminishing the through angle can reduce the motor’s speed. The motor’s turning is controlled by two relays, when 5 and 8 connector, 9 and 10 supply power, it is clockwise from the shaft direction, when 5 and 9 connect, 8 and 10 supply power, it is anticlockwise then. The speed-measuring facility in the motor transform the speed into impulse number which was provided to the PCB panel (the higher of the rotate speed, the more of the impulse is), the PCB panel control the motor’s speed through SCR. The methods of testing motor:

1) When the resistance between 6 and 7 is infinite, the motor appears heat protection, when 6 and 7 is always cut, the motor should be replaced.

2) If the resistance between 5 and 10 or 8 and 9 is infinite, the motor should be replaced.
