A washing machine inner barrel and a washing machine are disclosed, the inner barrel comprises a barrel bottom (300) and a barrel body (200) connected thereto. The barrel bottom (300) comprises a barrel bottom body (310) and a barrel bottom protective cover (320). The barrel bottom protective cover (320) is hermetically mounted on the bottom of the barrel bottom body (310) so that the entire outer surface of the barrel bottom (300) becomes a smooth surface. The outer surface of the barrel bottom protective cover (320) of the washing machine inner barrel is a smooth flat surface, which is more conductive to the cleaning effect of the particles on the inner barrel bottom (300). The barrel bottom protective cover (320) is hermetically connected with the bottom of the barrel bottom body (310) so that a reinforcing rib structure is in an enclosed space to prevent washing water from entering the reinforcing rib structure, thereby substantially eliminating the problem of bacteria breeding or fouling accumulation at
