Recently, the Beijing Consumers Association has conducted comparative experiments on some mainstream brand drum washing machine products sold in the market. The results show that in the washing ratio evaluation, the samples of Panasonic, Little Swan, Casarte, Midea and Haier reached "five stars"; in the performance test of sterilization and mite removal, the sterilization rate of 37 products with sterilization function reached 99%, and 27 prototypes with mite removal procedures could reach 100%.
It is reported that the comparative test samples were purchased by the staff as ordinary consumers from the e-commerce platform, involving 40 samples of 23 brands, and the purchase price ranged from 1499 yuan / unit to 5999 yuan / unit.
This comparative test tested the power consumption, water consumption, washing ratio (standard solid detergent), rinsing performance, dehydration rate, effective volume of washing cylinder, wear performance, sterilization performance, washing ratio (liquid detergent), mite removal performance and other items of 40 drum washing machine samples.

The higher the washing ratio, the better the washing effect of the prototype and the stronger the ability to remove stains. The washing effect of the drum washing machine in this test is better, but only 10 and 12 products can use standard solid detergents and liquid detergents to obtain a better washing ratio under the condition of less electricity consumption;
In terms of sterilization effect, the sample sterilization effect of this test is good. Among them, the sterilization rate of 37 products with sterilization function can reach 99%, and the sterilization rate of 34 products can reach 99.9%;
In terms of mite removal effect, 27 prototypes with mite removal procedures can achieve a mite removal rate of 100%;
In terms of power consumption, the power consumption of the drum washing machine in this test is low, and it can meet the requirements of the national standard Level 1, but there are obvious differences between the various machines. The factors that have a greater impact on the unit power consumption of the drum washing machine are the heating temperature and washing time of the washing water; generally more than 50% of the electricity is used to heat the washing water, and the higher the temperature of the washing water, the more power is consumed; at the same time, the longer the washing time, the more power is consumed;
In terms of rinsing performance, the rinsing effect of the full load of the drum washing machine in this test is mostly slightly lower than that of the half-load rinsing effect. The higher the rinsing performance, the better the rinsing effect of the prototype, and the lower the detergent residue;
In terms of wear performance, there is a clear correlation between the wear performance of drum washing machines and the washing effect. Fewer products with wear performance and wash ratio that can reach the highest star rating at the same time;
In terms of the effective volume of the washing cylinder, there are 33 drum washing machines with a rated capacity of 10kg, and the effective volume of the washing cylinder is obviously different. Among them, the effective volume of 9 product washing cylinders reaches more than 66L, and the effective volume of 24 product washing cylinders is between 62L and 66L. There are 2 sets of products with a rated capacity of 9 kg compared to some products with a rated capacity of 10 kg, which has a larger effective volume of washing cylinders;
In addition, the drum washing machine in this test has less electricity and water consumption, and the dewatering rate varies greatly.
