TECHNICAL FIELD

[0001] The present application generally relates to the technical field of cooling machines, and particularly relates to a cooling machine with a cleaning function. BACKGROUND

[0002] With the development of miniaturization of refrigeration equipment, the volume and structure of the cooling machine are increasingly limited, especially in the field of micro cooling machines; this trend makes it difficult to clean the liquid tank, especially for compact, immersed pump type and coil type cooling machines, which have complex internal structures and are difficult to clean effectively. After long-term use, impurities such as oil stains and scale are easily attached to the coil, which can significantly affect the refrigeration effect.
