Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device for freezers. Background Technology

[0002] Existing refrigerator cleaning devices clean refrigerators by scraping off ice. However, this method has limitations in applicability, can easily damage the inner wall of the refrigerator, and does not clean thoroughly, making it inconvenient to use. A Chinese patent disclosed a "Refrigerator Cleaning Device" with application number "CN202420871288.9". It cleans refrigerators by setting up a scraper. When scraping off ice, the cleaning tool may collide and rub against the inner wall of the refrigerator, causing damage to the inner wall. Ice and stains usually adhere to the corners and crevices of the refrigerator, which are difficult to remove by scraping, resulting in incomplete cleaning. Different refrigerators have different sizes and internal structures, and a fixed-size scraper cannot be well adapted to various refrigerators, resulting in limited applicability of the cleaning device.
