If you are tired of spending your free time washing dishes by hand, or the old dishwasher has already served its purpose, you need to think carefully about choosing a new dishwasher. Today's blog will be useful to those who do not yet know about all the features of dishwashers - here we will look at how it generally works and what functionality it has. Experienced users will also surely find something useful for themselves - in the course of the article you will learn about some of the innovative technologies of modern dishwashers.
How dishwashers work
All modern dishwashers work in cycles - their duration and other technological parameters are different, but the principle is about the same. Any washing program from start to finish is controlled by an electronic control board. This is a kind of "brain" of the installation, which analyzes the sensor data and issues commands to the appropriate nodes of the system.
The first stage of the cycle is a set of water through the inlet hose and the inlet solenoid valve. Depending on which washing mode was selected, the machine draws a strictly defined amount of water. In the device of all current dishwashers, there is an ion exchanger that rids the water of excess salts, softening it. Previously, users had to purify water with the help of additional devices - special detergents or filters.
After treatment with an ion exchanger, heating with a heating element follows. The water temperature rises to the desired value, then the detergent is added there - everything is ready for the start of the automatic wash. During the cycle, the detergent is added to the water several times.
The circulation pump starts to work, a strong jet is created, a soapy solution is supplied under the office. The nozzles are dispersed so that the sink affects all areas of the chamber, and the dishes are rinsed at different angles. Due to this, contamination in the form of fat and other food residues is eliminated quickly and efficiently. The pressure switch is activated when the dirty water level exceeds the allowable rate. The drain pump starts, and the liquid is drained from the dishwasher through the drain hose into the sewer. The process of collecting and softening water, as well as washing dishes, is repeated.
If there is an auto mode in the functionality of the equipment, special pollution sensors themselves determine how many more times it is necessary to rinse the dishes. The rinsing step with plain water follows when the plates are completely washed. At the same time, the jets are more voluminous - so there will definitely not be soap stains on the devices.
And finally, drying completes the working cycle. In some models, it is natural - at the end of the wash, the door automatically opens, and moisture is vented from the chamber in a few hours. But in most dishwashers, it is a turbo dryer. At the same time, the heating element and the fan work, which drives hot air through the chamber. Due to the forced circulation of heat, the plates dry in minutes.
Dishwashers of the new generation instantly notify the user of the end of the working cycle - either by sound notification or by light indication (for example, "Beam on the floor").
