In the washing machine of one of the main components is considered to be a brick. The shape and the number of different models, but the meaning is preserved. Without brick washing machine will start jumping and somersaults manufacture, and service life greatly reduced. Each master know that bearing replacement bricks relies removed. The device is a washing machine very interesting.
The insides of the washing machine
The water inside is not pumped. Fluid enters through the hose from the protection device from leaking under its own pressure. It uses an inlet valve. Pre-standing strainer. To clean the unit, shut off the water and remove the hose. Usually it costs a large spider net in a plastic sleeve. Do not expect that the washing machine will filter the water.
Put additional leakage protection devices, tools for cleaning. Connecting hose relies protection, or water is required to overlap constantly, leaving the house. Systems are designed to keep the flat (Akvastrazh, for example). Choose.
Washing machine starts with a protection device leakage. Rarely come across a model already with a hose equipped with solenoid valves. Dual hose and hollow inside. If there is a leak, the water rushes to the body of the washing machine, which is a double hole for the hose. Bursting inwards liquid triggers the sensor on the bottom of the float, the servo to avoid leaks tank. This design in a rarity in most cases from the drum water gets on the floor, the hose is not protected.
In the above case, until the appliance is unplugged, the fence does not occur, the valves closed. The hose contains a wire inside, with a separate connector on the rear housing of the washing machine. At the command voltage passes to the output valve is opened, water extraction begins. Sometimes the washing machine the device is complemented by a float valve on the bottom. The principle of action reminiscent of a similar sensor in the fuel tank. Standing water start to rise, as the switch is activated.
Today, a large widespread magnetic model where ferromagnetic float creates the desired field for the electronic board. There is no direct contact between the devices. As the level of the magnetic field intensity is enhanced, leading to protection operation.
The inlet valve is controlled by the electronic board according to the program, which is conducted countdown timer. This mechanism comprises a gear output terminals, the control devices (the motor mode, reverse, pump etc.). A device sometimes referred to as a programmer, which contributes to some confusion. However, the device is actually precisely counts the time, performs control units of washing machines. In models with automatic dosing of detergent control mechanisms are different. There cycle lasts for the required time, soiling level is determined by the transparency of water in the rinsing result. After the first stage of the electronics is able to say how long the process to spin (Fuzzy Logic - a flexible, fuzzy logic).
Selected washing machines are already able to determine the nature of the contamination, regardless of changing the flow rate of the powder. During the estimated level of contamination of the water after rinsing, the growth rate of the presence of foreign particles. For example, the fat dissolves slowly, so the washing machine at low contaminant levels growth rate makes the assumption that fatty stains advantageously.
Power washing machines dispensed. Modern technologies are based on inverter control, regulating the DC component of the input voltage, setting the engine speed and taking the energy network, as needed. Inverter Ingredients:
- The input voltage is rectified and filtered.
- The circuit generates a sequence of pulses necessary frequency and duty cycle (on which the actual voltage value depends).
That's the theory. In practice there are circuit switching power supplies where the input voltage 220 is cut through the power key generator to the desired frequency. By selecting the duty cycle and frequency change of the engine speed possible. In the case of a brushed motor method is not suitable. Said engine type dominates today. Then, the cut-off method is used when the negative and positive half-wave is truncated at a certain phase angle. For example, a pulse passes only half (from the top to decrease), resulting in effective voltage is halved, reducing the speed. To create the reverse direction change is made at the expense of inclusion of windings relay.
Speed changes by incorporating a large number of stator coils at high speed. The methods are more characteristic for asynchronous motors that are compatible with the inverter control. There Turnover depend directly on the frequency (at the shorted rotor). Commutator motor matter what value the parameter takes. The windings are generally recommended to feed a constant current to reduce the negative influence of the reactance. Amplitude method is suitable in both cases, a particular form is the introduction of the cut-off angle.
Technical characteristics of washing machines is entirely dependent on the engine, its smooth adjustment, the initial torque when pulling away. Inside stands pump, designed to pump wastewater into the sewer. At the entrance stands a cruciform filter requiring periodic cleaning. In the lower right corner of the washing machine is a cap. He gets out, giving access to the right parts. On the crosspiece often get hair removed every six months. Here there is an emergency discharge of water if the light is turned off or the pump has refused. Prepare a flat basin for work.
The drum is made of plastic or steel inside the cylindrical tank. Parameter refers to when the technical characteristics of the washing machine write:
- steel tank;
- plastic tank.
First harmless, but the durability of the current level of technology development is easy to argue. The principle of operation of the washing machine during the spin cycle provides an extremely fast rotation of the drum. If the mechanism is centered, still there are significant vibrations. To quench tank mounted on the bricks of various shapes. As a result, the inertial properties of the system grow. The tank is attached to the body to stretch and spring suspension, the number and type depend on the model of the washing machine. Without such tricks would take Herculean efforts to keep the equipment in place during the spin cycle. The parameters choose washing machines with caution. Experts do not recommend to take the products, where turnover exceeds the spin cycle on 1200. It is harmful to the laundry.
At the bottom of the tank is worth TEN, the program heats the water to the desired temperature. The temperature sensor is present and placed in a tube.
Cycle in a washing machine
The water is taken by the team when the door is closed tightly. The inlet valve opens, the water tray without passing through the detergent falls into the tank. It begins rinsing before the main wash. Most cold water and being used to remove a portion of contaminants, without lagging powder. The operating principle of Fuzzy Logic washing machine at said step requires estimation of the nature, number and growth rate of contamination. According to data produced by the installation for the next cycle.
At the second stage, the water is pumped from pump tank is drained into the drain through the drain hose. Recruited new passing through the powder tray by washing agent. Water is heated to the desired temperature, main wash begins. According to the authors, the preheating of water followed by addition of the powder would reduce scale formation. Therefore, it is recommended to add inside Calgon. The drug is designed for tap water, carefully read the instructions for SMS, so as not to harm the washing machine. We emphasize that the excess powder and excess Calgon, rinse cause excess deposition on the bottom of the tank, leading to the formation of scale on PETN, degrade the quality of washing.
Usually the more the better, it does not work.
