A product may not only use one trademark, but also use multiple trademarks. You said that Haier and cartoon characters are trademarks of Haier brand. Even the same model has different production batches. Perhaps it is normal for manufacturers to use various trademarks in order to meet different consumer recognition habits in the market. Some customers like simple design style, and some customers only know cartoon villain logo. This does not affect the use of the product. Don't worry.
