Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-3 , a dryer directly drives the inner drum structure through a DD direct drive motor, including a drum 1. A mounting seat 2 is fixedly connected to the rear end of the drum 1. A base 3 is fixedly connected to the bottom of the drum 1. A rotating door 4 is rotatably connected to the front end of the drum 1. A U-shaped handle is fixedly connected to the side wall of the rotating door 4. A protective sleeve is sleeved on the outer wall of the U-shaped handle. The protective sleeve is made of rubber, and the rotating door 4 can be rotated open to pick up and place clothes.

[0022] The drum 1 is communicated with the mounting seat 2. A dust-proof net 5 is fixedly connected to the mounting seat 2, which can remove dust from the flowing air and ensure the cleanliness of the clothes. The rear end of the dust-proof net 5 is arranged in the same vertical plane as the rear end of the mounting seat 2. A motor 6 is fixedly connected to the inner wall of the mounting seat 2. The motor 6 is a DD direct drive motor. The end of the front output shaft of the motor 6 is fixedly connected to an inner drum 7. A plurality of through holes 8 are arranged at equal intervals through the inner drum 7, which can make the air circulate, and the hot air contacts the clothes sufficiently to take away moisture. The end of the rear output shaft of the motor 6 is fixedly connected to a wind wheel 9, which can inject external air into the drum 1.

[0023] Two electric heating wires 10 are fixedly connected to the inner wall of the mounting seat 2. A protective tube is arranged outside the electric heating wires 10. The two ends of the protective tube are respectively fixedly connected to the inner wall of the mounting seat 2. The electric heating wires 10 can heat the air into hot air, which has a good drying effect on the clothes, and plays a protective role through the protective tube. The protective tube is made of high-temperature resistant material. A drainage hopper 11 communicated with it is fixedly connected to the rear end of the mounting seat 2, and a small amount of water is discharged through the drainage hopper 11.

[0024] Two ventilation pipes 12 communicated with it are fixedly connected to the side wall of the drum 1. Both of the two ventilation pipes 12 are fixedly connected to and communicated with the side wall of the base 3. An air outlet is arranged through the base 3. A filter screen is fixedly connected to the inner wall of the air outlet. The front end of the filter screen is arranged in the same vertical plane as the front end of the base 3.
