The invention belongs to the technical field of washing equipment, and provides a cover locking assembly for a cleaning machine and the cleaning machine. The cover locking assembly for the cleaning machine and the cleaning machine aim to solve the problem that an existing washing machine is poor in sealing effect. The cleaning machine comprises a cleaning machine body and a shell. The cover locking assembly comprises a cover body, at least one lock rod and lock catches in one-to-one correspondence with the lock rods; the cover body is used for covering and sealing a cleaning machine body; thelock rods are arranged on the cover body and extend towards one side of the shell; the lock catches are arranged on the shell and can be inserted and connected with the corresponding lock rods. According to the cover locking assembly for the cleaning machine and the cleaning machine, insertion and separation between the lock rods and the lock catches are realized through up-and-down movement of the lock rods, so that the sealing and opening between the cover body and the cleaning machine body are realized, the sealing effect of the cleaning machine can be improved, namely splashing and water leakage are avoided when the cleaning machine works, the structure is simple, and the cover locking assembly can be applied to cleaning machines of various structures.
