Should the dishwasher choose a micro DC water pump or a micro AC water pump?

The world's first dishwasher was invented in Shelbyville, Illinois by Josephine Cochrane, a female inventor who received patent number 355139 on December 28, 1886. The dishwasher was exhibited at the Chicago World's Fair in 1893, and Josephine Cochrane went on to start a dishwasher company of her own.

The emergence of dishwashers has greatly reduced the burden of people working in the kitchen, completely liberated their hands, reduced daily family friction, and increased the atmosphere of family harmony. Now, whether in restaurants or at home, dishwashers have become more convenient and efficient, bringing people neatness, hygiene and ease.

Have you noticed that the dishwasher can't do without the nozzle to clean the dishes. The reason why the water sprayed from the nozzle can wash the dishes is that the dishwasher is equipped with a dishwasher water pump. The high-pressure washing force generated by the water pump will wash away the oil stains and food residues on the tableware and chopsticks, so as to achieve the purpose of cleaning the tableware and chopsticks. .

At present, there are two types of dishwasher water pumps: one is a micro DC water pump, and the other is a micro AC water pump. Which one is better?

Micro AC water pump is a small water pump whose power source is AC. 220V mains is used, and the commutation is changed by the frequency of 50Hz of the mains, and the speed is very low. There are no electronics in the AC water pump and it may be exposed to high temperatures.

Advantages and disadvantages of micro AC water pump:

Advantages: cheap price, many manufacturers.

Disadvantages: large volume, loud noise, heavy weight, inconvenient to carry, high protection level requirements, and the possibility of electric shock if used improperly.

Micro DC water pumps refer to water pumps that use DC power to drive brushless motors. Using 4.5V~24V DC power supply, the micro DC water pump adopts electronic components for commutation, no need to use carbon brush for commutation, and uses high-performance wear-resistant ceramic shaft and ceramic bushing. wear, so that the life of the brushless DC magnetic pump is greatly improved.

Advantages and disadvantages of micro DC pumps:

Advantages: long life, low noise below 35 decibels, high precision, good shock resistance.

Disadvantages: high price.

At present, most dishwashers use AC water pumps, but with the improvement of people's living standards, the quality requirements for household appliances are getting higher and higher, DC water pumps will gradually replace AC water pumps, because the disadvantages of AC water pumps are exactly what people want to improve life quality requirements.
