Why can't a dishwasher wash an iron pan? The principle of an automatic dishwasher

Automatic dishwashers use high-temperature and high-pressure water to mechanically wash the surface of tableware 360 ​​degrees. After adding detergent, it can decompose the surface residue and dirt of tableware. It is very popular among office workers nowadays. Some friends asked if it can wash pots? The following is a sharing organized for you!

Why can't the dishwasher wash iron pots?

The reason why iron pans cannot be washed in dishwashers is mainly related to the operating principle. When iron pans are sealed, they are easily washed due to thermal expansion and contraction, which can cause the anti-rust coating to fall off, thus shortening the service life of the iron pan. In addition, the area of ​​iron pans is relatively large, and forcing them into the dishwasher may damage the dishwasher. Therefore, it is more appropriate to wash iron pans by hand, and you should also pay attention to maintenance at ordinary times.

The reason why a dishwasher cannot wash iron pans mainly depends on the operating principle of the dishwasher. Because the dishwasher needs to spray water and dry the pan during operation, the paint in the iron pan will easily fall off after the changes of thermal expansion and contraction in a sealed state, which will increase the possibility of rusting of the iron pan.

The dishwasher itself provides a cleaning function for dishes and chopsticks. The area of ​​​​iron pans is too large, and some iron pans cannot even be placed in the dishwasher. In addition, the dishwasher itself has many parts. If the iron pan is stuck in the dishwasher, it will affect the service life of the dishwasher and damage the dishwasher.

Because there is a special anti-rust coating inside the iron pan, you should be careful when cleaning it to avoid rubbing the coating off with a steel wool. You should also pay attention to maintenance when using the iron pan. You can put fat in the iron pan to refine oil and use grease to moisturize the inside of the iron pan to prevent rust.

Principle of automatic dishwasher

The principle of automatic dishwashers is to use high-temperature and high-pressure water flow to mechanically flush the surface of tableware 360 ​​degrees. The detergent can decompose the residue and dirt on the surface of the tableware. The hot water soaks and expands the food residue, which can quickly decompose and remove the oil and residue on the tableware in a short time.

Automatic dishwashers use high-temperature and high-pressure water flow to mechanically flush the surface of tableware 360°. After adding detergent, it can decompose the surface residue and dirt of the tableware. The hot water can soak and expand the food residue, and can quickly decompose and remove the oil and residue in a short time.

Ultrasonic dishwashers use the principle of ultrasonic cleaning. Ultrasonic waves vibrate when passing through a liquid medium, causing the liquid molecules to produce alternating positive and negative impacts, followed by intense micro-explosions and impacts that can remove dirt from the surface of objects.

A jet dishwasher uses high-temperature and high-pressure water jets to rinse the surface of tableware in all directions. Its effect is the same as that of an automatic dishwasher. The detergent decomposes the dirt and residue on the surface of the tableware, and the hot water will soak and expand the food residue, causing the dirt to fall off quickly.

Dishwasher still has water after drying

After the dishwasher is dried, there will still be water in it. This may be because during the last rinse, the high temperature water raised the temperature of the dishes and evaporated the water in the dishwasher. However, the water vapor will re-solidify when it encounters the inner wall of the dishwasher. This is a normal phenomenon. After each use of the dishwasher, you can open the door a small gap to prevent water.

If you find that there is still water inside the dishwasher after drying, it may be that during the last rinse, the high temperature water raised the temperature of the dishes and evaporated the water on the surface of the dishwasher. However, when the steam encounters the inner wall of the dishwasher, it re-condenses. This is a very normal phenomenon and there is no need to worry about the dishwasher malfunctioning.

If you don't want water to appear after the dishwasher is dried, open the door a little after each use to keep it ventilated so that the high-temperature evaporated water vapor can come out. You also need to clean the dishwasher regularly and take sterilization measures to prevent a large number of bacteria from being generated inside.

If the dishwasher is not cleaned for a long time, there will still be water in it even after it is dried. You can usually wipe the dishwasher with a wet towel, then spray white vinegar inside to disinfect and sterilize it, and then wipe it again with a clean towel to prevent the dishwasher from getting damp and producing odor.
