The invention discloses a convenient-to-wash water dispenser. The convenient-to-wash water dispenser structurally comprises a water inlet cover, a smart seat, an automatic washing device, a water tank, a separation plate, a filter, a main body shell body, a pump body and a checking door, wherein the smart seat is arranged on the top surface of the main body shell body; the convenient-to-wash waterdispenser is provided with a mounting and detaching mechanism, a travel switch, an intermittent transmission structure, a transmission structure, a rotary hoisting structure and the like; the intermittent transmission structure drives the transmission structure to do reciprocating motion by starting a small motor through the travel switch, so that a forward and backward rotation structure can rotate in clockwise and anticlockwise directions and the rotary hoisting structure rotates; finally, a washing structure is driven to automatically move up and down to washing an inner wall of a pipeline; an auxiliary pushing structure is arranged so that the rotary speed of the rotary hoisting structure is improved; a hoisting speed is accelerated and a friction force is increased, so that the cleaning intensity is improved; the washing structure also can be replaced by utilizing the mounting and detaching mechanism; the pipeline is sequentially washed by utilizing a hairbrush and then is scrubbed by utilizing sponge, and a water pump does not need to be used for pumping water for washing, so that the washing time is shortened.
