Focus on the key! I chose the washing machine to understand these four points!
Washing clothes should be the most annoying household chores than washing dishes after meals. In modern urban life, washing machines are essential household appliances for every family. Nowadays, there are more and more products on the e-commerce website. The overwhelming information flow flows through the entire website page. The products and advertisements are full of eyeballs. How to choose the most suitable and cost-effective products on the shelves? It is difficult. In response to this problem, then I will learn some technical vocabulary when I purchase a washing machine for everyone. I chose to know the washing machine. First, the difference between brush motor and brushless motor Brush motor: As the name implies, it is a motor with a brush. The “brush†is a carbon brush. This is the most intuitive observation from the name. The current of the brush motor is completely converted into a magnetic field, and the power utilization rate is high. The brush motor is a traditional product, the structure is not complicated, the performance is relatively stable and mature, it is not easy to cause problems, it is convenient when it is needed for maintenance, and the price is cheap. However, due to the principle of operation of the motor, heat is generated during the friction process and a certain amount of noise is generated. Moreover, the carbon brush has been rubbed for a long time and needs to be changed within two to three years. Fortunately, the replacement operation is not difficult, and the technical difficulty is not high. Brushless motor: It consists of a motor body and a driver, and is a typical mechatronic product. Power electronics are required to provide positive and negative alternating voltages to simulate brushes. The brushless motor is an upgraded product, and its life is longer than that of a brushed motor. Due to its working principle, there is no mechanical wear of the carbon brush, resulting in low noise. However, the control circuit is more complicated, and the motor maintenance will be more troublesome and the price will be more expensive. Second, the difference between the drum and the pulsator Washing machine: The bottom of the barrel of the washing machine has a disc wheel with protruding ribs. Driven by the pulsator, the water flow in the bucket forms a vortex that is right-handed and sometimes left-handed, which drives the fabric to rotate and roll, so that the dirt on the clothes can be removed. The price of the washing machine is medium to low, but it is very expensive and easy to cause the clothes to entangle, the laundry is not uniform, and the wear rate of the clothes will be relatively high. Drum washing machine: The washing method of the drum washing machine is designed to imitate the principle of hammer hammer hitting clothes, and uses the huge centrifugal force generated when the drum rotates to make repeated movements, and the washing powder and water jointly work to wash the clothes. The price is relatively high and the electricity is charged. The working operation is noisy, but the water is saved, and the wear rate of the clothes is low, and the low degree of washing needs to be washed with hot water to make up. Third, the difference between upper drainage and lower drainage Drainage: In daily life, the washing machine we use is generally drained, and the lower drain is used by most washing machines and small drum washing machines. The drainage method has a simple structure, and the water is directly discharged from the bottom by using the pressure difference of the water. The disadvantage is that it is directly discharged into the floor drain and cannot be used twice, and the washing machine can only be placed near the floor drain. Upper drainage: It is mostly used in medium and high-end drum washing machines. The water is pumped out by the pump and discharged into the container of water, which can be used for secondary use. However, the drain pump needs electricity, and the operation process will generate noise, and the structure is complicated and troublesome to maintain. Fourth, the difference between drying and without drying There are many washing and drying machines on the market. This is usually based on the situation and demand. The drying is more suitable for the rainy season and the wet area, but the washing machine with drying is not only different in price, but also there is no Naturally dry and sun-sterilized, anti-bacterial and dustproof. Moreover, the washing machine needs to be cleaned and kept clean all year round to avoid secondary pollution and odor. Summary: In general, with the advancement of technology, modern household appliances are more intelligent and advanced. At the same time, as technology matures, prices will become lower and lower. When purchasing household appliances, we mainly judge according to our own situation, and then combine brand and cost performance to consider comprehensively. We must not blindly follow the guides and advertising promotion. Before buying, we can look at the popular science posts online to learn more about the relevant knowledge. Suitable product.
