Description

Technical Field

[0001] The utility model relates to the technical field of washing machine door covers, and more specifically to an automatic opening device for a washing machine door cover. Background Art

[0002] Currently, washing machines are generally divided into front-loading washing machines and pulsator washing machines. Front-loading washing machines use a hammer-like method to wash clothes. Most front-loading washing machines consist of a stainless steel inner drum, a mechanical program controller, an outer shell protected by phosphate treatment, electrophoresis, and spray coating, and several cement blocks. These blocks are used to balance the enormous centrifugal force generated by the rotating drum, enabling repeatable movement. Washing machines are commonly used in textile testing. Many physical testing items on textiles require washing in washing machines according to standard requirements. Using an electric motor to drive the drum, they automatically complete the washing, rinsing, and dehydration processes.

[0003] For example, the drum washing machine with the prior art publication number CN207537728U effectively saves space inside the box and reduces the size of the drum washing machine in the depth direction, so that the drum washing machine of the utility model has a wide body and ultra-thin design effect, greatly reducing the occupied space.
