Which Button is the One-Touch Defogging?

One-touch defogging is indicated by a fan-shaped symbol with three vertical wavy lines. Introduction to the One-Touch Defogging Button: The one-touch defogging function utilizes the car's air conditioning system to quickly and effectively remove fog from the windows. When driving in winter, you may notice fog forming on the windows within minutes. This occurs due to the temperature difference between the inside and outside of the car, causing condensation on the cold glass. Some drivers use a towel to wipe the fog away, but it often reappears shortly after. In such cases, the one-touch defogging function can be used. Simply press the one-touch defogging button inside the car and adjust the air vents to the front windshield position. The fog on the windshield will disappear quickly. How the One-Touch Defogging Function Works: Car defoggers are used to separate liquid droplets from gases in the tower to ensure mass transfer efficiency, reduce valuable material loss, and improve the operation of the compressor after the tower. Typically, a defogger is installed at the top of the tower. It can effectively remove droplets of 3-5um. Installing a defogger between trays not only ensures the mass transfer efficiency of the trays but also reduces the distance between them. Therefore, defoggers are mainly used for gas-liquid separation and can also serve as air filters for gas separation. Additionally, wire mesh can act as a buffer for various instruments in the instrumentation industry to prevent radio interference or as an electronic shield.
I often encounter the problem of foggy windows obstructing my vision while driving, especially on rainy days or cold mornings. That one-touch defog button is usually located on the car's climate control panel, marked with "FRONT" or a fog symbol like a combination of windshield and water droplets. When pressed, the vehicle automatically initiates the procedure: the fan accelerates airflow, the AC switches to defog mode, and the airflow focuses on the front windshield. Its position varies by model - in some SUVs it's positioned lower on the center console, while in compact cars it might be near the steering wheel shortcut area. I've used it several times with super-fast results; the fog dissipates within seconds, eliminating the hassle of manually adjusting fan speed and temperature. This feature not only enhances safety but also saves time, particularly during traffic jams when maintaining driving focus is crucial.
