The invention relates to the technical field of cleaning brushes, in particular to a cleaning brush capable of cleaning solid kitchen appliances, which comprises a driving structure, a reversing structure, an angle adjusting structure, a cleaning structure, a storage structure, a reset structure and a heat exchange chamber. The driving structure is released, the reset structure enables an accommodating cavity in the driving structure to be enlarged, the reversing structure is regulated, the storage structure is conducted with the driving structure, and the storage structure generates negativepressure, so that the sweeps are more convenient to store in the storage structure, hot water can be conveniently controlled to enter the driving structure from the storage structure through the driving structure; reversing structure is then adjusted, the driving structure is communicated with the heat exchange chamber, and the driving structure is pressed, so that hot water is discharged to the heat exchange chamber from the driving structure, the temperature of the storage structure is increased, small-area fallen ice blocks in the storage groove of the refrigerator can be conveniently melted through the storage structure, ice crumbs are more convenient to clean, the melting speed of frozen food is decreased, and then electric energy is greatly saved.
