The "Low-speed Crisis" of Blenders
Click on this video link, and you'll step into a discussion about a peculiar phenomenon regarding blenders—why do some blenders break down faster the more carefully they are used? There's a lot to this, so let me explain it in detail.
The story begins with a household blender that had been on sale in the European market for many years. In Europe, it was quite popular, with sales soaring and the customer complaint rate extremely low. Seeing such excellent results, the company confidently launched it into the global market. However, the ideal is plump, but the reality is skinny. Soon after the product was put on sale, a major problem emerged. The customer complaint rate skyrocketed, and the majority of the complaints were due to the motors burning out.
At first, the company's technicians thought there was an error in the raw materials or the production process. They conducted a comprehensive investigation of the production process, carefully checking every aspect from the source of raw material procurement to each step on the production line. The composition of each batch of raw materials was analyzed, and every parameter of the production process was repeatedly verified. However, in the end, they found nothing. The problem still remained as mysterious as a fog, leaving people completely puzzled.
Later, through in - depth analysis of the complaint regions, a crucial piece of information emerged. The complaint rate in Europe has basically remained unchanged, while the regions with high complaint rates are mainly concentrated in Southeast Asia, South Korea, and China. This is rather strange. Why is there such a significant difference in the same product across different regions?
After further careful investigation, the truth gradually became clear. It turned out that users in these three regions all had one thing in common: they preferred to use the low - speed setting. In Indonesia, due to insufficient power supply, customers were worried about tripping the circuit breaker, so they chose to use the blender on the low - speed setting. In South Korea and China, some elderly people, influenced by traditional ideas, thought that using the low - speed setting would make the product last longer. However, what they didn't expect was that this approach actually backfired. When using the low - speed setting to blend foods like carrots, a perfectly good blender would burn out in just three to five minutes.
What's the principle behind this? For blenders with three or more speed - regulation functions, the rotational speed is usually adjusted by varying the resistance or the number of coil turns. When using a low - speed setting to blend foods with high resistance, the current in the motor coil will increase, and the temperature will also rise rapidly. Although the blender is equipped with a temperature protector, since the temperature rises too fast, sometimes the protector doesn't have enough time to work, and the motor may burn out.
If you find that your home blender sometimes suddenly stops working and then can resume operation after a while or after unplugging the power plug, it's very likely that the speed setting you've chosen is too low. However, it should be noted here that the problems with two - speed blenders are relatively minor. This is because two - speed blenders usually use diode speed regulation. With this speed - regulation method, the probability of the motor burning out is relatively low.
The original intention of setting the blender to the low - speed mode is actually to mix food without generating many bubbles during the mixing process. It is not designed to crush food. However, many users are not aware of this, which has also led to some unnecessary troubles.
Now on the Internet, we can still see some complaints from customers. They say that the blender breaks down soon after they buy it home, and the customer service only mechanically and repeatedly emphasizes that the product has passed the inspection and there is no quality problem. This actually reflects the problem of information asymmetry between the manufacturer and the customers. The manufacturer should clearly remind customers at a prominent position that the low - speed gear cannot be used for blending foods with high resistance. Perhaps not all blender manufacturers understand the customers' usage habits. They take it for granted that all customers can use the blender correctly.
This also reminds us that during the product promotion process, we need to adjust products according to different markets. Different environments, cultures, and living habits can all have an impact on the usage results of products. Only by fully considering these factors can we enable products to better meet consumers' needs and reduce unnecessary after - sales problems.
