Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a balancing block adjusting device. Background Art

[0002] With the development of society, washing machines have become an indispensable household appliance in people's daily lives, and drum washing machines are currently the most commonly used type of washing machines. Since various parts are installed at the rear of the water tank of a drum washing machine, the weight is unbalanced. In order to ensure that the drum maintains dynamic balance under high-speed rotation during washing, it is usually necessary to install a balance block in the washing machine. The balance block is usually fixedly connected to the washing machine by bolts.

[0003] In practical applications, the weight of the balance block is a key factor affecting its balancing performance. Some washing machines may require a lighter balance block to achieve dynamic balance, while some washing machines may require a heavier balance block.
