According to the data monitoring of domestic authoritative institutions, the retail sales of dishwashers in January 2022 were 900 million yuan, up 27.3% year on year. The retail sales of dishwashers in the offline market reached 200 million yuan, up 12.9% year on year. It can be seen from this set of data that the dishwasher has gradually been popularized to most families and has become one of the indispensable household appliances.

The first dishwasher in the world was invented by female inventor Josephine Cochran in Shelby Ville, Illinois. She obtained the patent number 355,139 on December 28, 1886. The dishwasher was displayed at the 1893 Chicago World Expo, and Josephine Cochran later founded his own dishwasher company.

The appearance of dishwasher 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 the restaurant or at home, washing dishes has become more convenient and efficient, Bring people tidiness, sanitation and relaxation.

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

At present, there are two kinds of water pumps for dishwashers: one is micro DC water pump, and the other is micro AC water pump. Which is better?

The micro AC water pump is a small water pump with AC power supply. 220v mains power is adopted, and the commutation speed is very low by changing the frequency of 50 hz mains power. There are no electronic components in the AC water pump, which can withstand high temperature.

Advantages and disadvantages of micro AC water pump:

Advantages: low price, many manufacturers.

Disadvantages: large volume, loud noise, heavy weight, inconvenient to carry, high protection level requirements, and potential electric shock due to improper use.

Micro DC water pump is a kind of water pump that uses DC power supply to drive brushless motor. 4.5v~24v DC power supply is adopted. The micro DC water pump uses electronic components for commutation without using carbon brush for commutation. High performance wear-resistant ceramic shaft and ceramic shaft sleeve are adopted. The service life of brushless DC magnetic pump is greatly improved due to wear.

Advantages and disadvantages of micro DC water pump:

Advantages: long service life, low noise of less than 35db, high precision and good seismic 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. Shenpeng DC water pumps will gradually replace AC water pumps, because the disadvantage of AC water pumps is that it is people's requirements for improving the quality of life.
