[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an anti-knotting drum drying machine and a method for using the same, comprising a machine body and a drum, wherein a rotating disk is rotatably connected to the inner wall of the machine body, a slot is provided on the outer wall of the drum, and the drum is plugged into the rotating disk through the slot; A feed port is provided on the outer wall of the machine body, one end of the drum extends to the feed port of the machine body, and a machine door for opening and closing the feed port is rotatably connected to the outer wall of the machine body; A driving assembly is installed inside the machine body, and the driving assembly is used to drive the drum to rotate and to rotate the drum forward and reversely; A plurality of through holes are evenly opened on the outer wall of the drum, and a casing is arranged on the outer side of the drum; A gap is left between the casing and the drum, a fixing plate is fixedly connected to the outer wall of the casing, and the casing is connected to the inner wall of the machine body through the fixing plate; A cleaning structure for cleaning the through hole of the drum is arranged on the top inner wall of the casing; A heating structure is provided at the bottom of the machine body, and the heating structure and the casing form a ventilation channel; The purpose of the above arrangement is that the clothes enter through the feed port of the machine body, one end of the drum extends to the feed port, and the machine door is used to open and close the feed port. After the clothes are dried in the drum, the door is opened to take them out; The driving assembly is installed inside the machine body, driving the drum to rotate and realize forward and reverse rotation. This design can prevent the clothes from getting tangled in the drum, because forward and reverse rotation can continuously change the position of the clothes and avoid the clothes from getting tangled together. The heating structure at the bottom of the machine body provides heat, and the hot air enters the drum through the ventilation channel to exchange heat with the clothes. The through holes on the outer wall of the drum allow the hot air to enter the drum, and also allow the moisture in the clothes to evaporate and be discharged from the drum; The shell is located outside the drum, with a gap between it and the drum. The shell is used to collect the lint and impurities dropped from the clothes. The fixing plate of the shell fixes it to the inner wall of the machine body. The cleaning structure on the inner wall of the top of the shell is used to clean the through holes on the outer wall of the drum to prevent the through holes from being blocked, thus ensuring smooth heat exchange and ventilation. The clothes are constantly turned over in the drum and fully contacted with the hot air, and the moisture gradually evaporates. The evaporated moisture is discharged through the holes in the drum, and the hot air circulates continuously to maintain the appropriate humidity in the drying environment until the clothes reach the required degree of dryness.

This design helps to support the drum and plays an auxiliary and stabilizing role when the drum rotates, reducing the shaking of the drum and the noise caused by the rotation process, making the rotation smoother, which is conducive to the tumbling of clothes in the drum and avoiding tangling.

[0008] Further, the driving assembly includes a first motor and a rotating shaft, the first motor is mounted on the bottom inner wall of the body, and a first driving wheel is mounted on the output shaft of the first motor; The rotating shaft is rotatably connected to the inner wall of the machine body, a second driving wheel is installed on the outer wall of the rotating shaft, and a transmission belt is connected between the first driving wheel and the second driving wheel; A third driving wheel is installed at both ends of the rotating shaft, a wheel groove is provided on the outer wall of the third driving wheel, and a driving belt is connected between the wheel groove of the third driving wheel and the outer wall of the drum; The purpose of the above-mentioned arrangement is that the first motor in the driving assembly is installed on the inner wall of the bottom of the machine body, and the first driving wheel on its output shaft drives the second driving wheel on the rotating shaft to rotate through the transmission belt, and then the third driving wheels at both ends of the rotating shaft drive the drum to rotate through the driving belt. This multi-stage transmission method can effectively transmit the power of the motor to the drum, realize the forward and reverse rotation function of the drum, and continuously change the position of the clothes in the drum through forward and reverse rotation to prevent the clothes from getting tangled.

[0009] Furthermore, a rotating plate is rotatably connected to the inner wall of the drum; The purpose of the above-mentioned setting is that the rotating plate connected to the inner wall of the drum rotates.
