In the fast-paced modern life, the daily bustle for work, people are full of hope after work can unload tired, relax. However, when I got home and saw the piles of dishes waiting to be washed on the dining table, my pleasure vanished and I was filled with annoyance. At this point, if a cleaning savior can appear, to wash dishes easily resolve the problem, it is a great happiness. In fact, the dishwasher is such a existence. Here, we delve into the mystery of how dishwashers work and the science behind them.

1.Pre-washing stage

When you press the Start button on the dishwasher, an orderly cleaning operation begins. The first stage is the prewashing stage, where cold water pours in from the intake pipe like an inspired dancer, splashing evenly on the surface of the cutlery through a rotating spray arm. These water flow with specific angle and pressure, form omni-directional, no dead angle of the water curtain, the tableware loose residue, quickly washed down. The process is deceptively simple. It was like a well-planned reconnaissance operation to remove large particles from the battlefield so that they wouldn't clog the pipes and affect the cleaning efficiency during the subsequent main wash, for the follow-up of the depth of cleaning to prepare, so that the tableware can be in a clean state to meet the main wash phase of the challenge. Some smart dishwashers are also equipped with advanced smart sensors that can sense water flow resistance in real time and automatically adjust the pre-washing time according to the dirtiness of the tableware to ensure accurate and efficient cleaning.

2.Main washing stage

After the pre-washing, the main washing stage officially launched, which is the core of the dishwasher cleaning campaign. At this point, the PTC heater inside the dishwasher kicks in, rapidly raising the water temperature to 65-75 °C. This temperature range is the bane of grease, which dissolves stubborn grease efficiently, also can activate the biological enzyme activity in the detergent fully, let these clean small guard display the biggest potency. At the same time, the high-pressure pump began to run at full speed, generating up to 30,000-40,000 PA of jet pressure. The water gushes out from the revolving spray arm, forms every minute 150 above three-dimensional scours, looks like the dense arrow rain, omni-directional, does not have the dead angle to attack on the tableware the greasy dirt. Some high-end models use"Hurricane Wash" technology, which uses a bottom-pressurized nozzle to provide a stronger cleaning force for the lower cutlery, even in difficult-to-clean areas such as the grooves of deep bowls, and it can be conquered.

3.Rinsing and drying

After the main stage of washing, rinsing and drying phase followed, for this clean-up on a successful conclusion. During the rinsing stage, the high-temperature water column at 75 °C cooperates with the secret weapon of brightener to scan the tableware more than three times to remove the detergent residue, so that it is much lower than 0.1 ppm, giving the tableware a new luster. At the same time, the soft water system with the help of Ion-exchange resin adsorption of calcium and magnesium ions, effectively prevent the scale on the tableware deposition, let the tableware lasting clean and bright. The hot air circulation system heats the air to 105 °C, and with the condensation structure, the water vapor is condensed and discharged. Some models of crystal bud drying technology use natural ore moisture absorption and zero energy consumption to achieve perfect drying, green and efficient.

4.Faqs

(1). Water stain problem: many users found that water stains appear after washing the glass, which is often related to water quality. Hard water is rich in calcium and magnesium ions, which is easy to form scale residue in high temperature environment. At this point, only with the use of special soft water salt, soft water salt ions can effectively replace calcium and magnesium ions in water, reduce the hardness of water quality, from the root to solve the problem of water stains.

(2). Plastic deformation puzzle: when plastic dishes deform in the dishwasher, it is likely that the heat program was misused. Plastic materials are more sensitive to temperature, and the heat resistance of different kinds of plastics is quite different. Therefore, in the use of dishwasher cleaning plastic tableware, be sure to choose 50 °C below the gentle mode, to avoid high temperature caused by tableware deformation.

(3). The truth about saving water: the answer to the question of whether dishwashers save more water than hand washing is unequivocally yes. Authoritative data shows that dishwashers use only 1/4 the amount of water for a single wash. Thanks to its precise water flow control and recycling system, every drop of water can maximize the cleaning efficiency inside the dishwasher, truly achieving efficient water saving.

Conclusion

Now, I believe you have fully understood the working principle of the dishwasher. With the development of science and technology, The Dishwasher has evolved from a simple cleaning tool to an indispensable core hub in the kitchen ecosystem. It not only liberates our hands, but also allows us to have more time with our families in our busy lives.
