Clothes washing and drying machine

The utility model provides a bubble intrusion prevention structure of clothes cleaning and dry machine. The utility model can prevent detergent bubbles from flowing into the blast pipe that is applied to dry clothes. Wherein, a pipe lock gate(81) is arranged near the air suction orifice(11) of the air heating blast pipe(13). The air suction orifice(11) is connected with the air suction orifice(11) that is arranged at the bottom of the water containing barrel(3). The lock gate(81) can at least turn off the pipe of the air heating blast pipe(13) during the process of washing. Thus, even the large amount of bubbles are produced in the water containing barrel(3) and overflow from the air suction orifice(11), the utility model can prevent the detergent bubbles from intruding into the air heating blast pipe(13) and the hot pump module(20). Meanwhile, the pipe lock gate(81) is opened to during the process of drying, which will not influence the circulation of air.
