The invention relates to an intelligent water-free cleaning type touch-screen coded door access lock. The intelligent water-free cleaning type touch-screen coded door access lock is characterized in that an existing coded lock structure is used as the foundation, an intelligent water-free screen cleaning structure is introduced, hot air blowing operation is performed on a code touch screen (9) by a second miniature fan (6), an electric heating plate (7) and lower through air holes (10) in the bottom edge of the embedded frame of the code touch screen (9) so as to achieve fog covering of the surface of the code touch screen (9), then an electric-control telescopic rod (2) controls a windscreen wiper (8) to move on the surface of the code touch screen (9) so as to remove fog covering the surface of the code touch screen (9), the operation is repeated to clean residual fingerprints on the surface of the code touch screen (9), the potential safety hazards caused by the residual fingerprints can be effectively avoided, and the use safety of the coded lock is increased.
