[0087] The present application can automatically open the sliding cover 22 by arranging the automatic telescopic device 4 and the sliding cover limiting device 6, which can control the sliding cover 22 to partially separate from the drying drum 2 to open the clothes feeding opening 21 when the sliding cover 22 moves outward with the drying drum 2 by a preset distance when the automatic telescopic device 4 drives the drying drum 2 to move outward, and can control the sliding cover 22 to stop moving to move the clothes feeding opening 21 to the position of the sliding cover 22 to be closed when the sliding cover 22 moves inward with the drying drum 2 by a preset distance when the automatic telescopic device 4 drives the drying drum 2 to move inward. The present application can automatically open and close the clothes feeding opening 21 during the outward and inward telescopic movement of the drying drum 2, and does not need the user to manually open the sliding cover 22, greatly improving the intelligence and user experience of the clothes dryer.

[0088] Preferably, the left and right sides of the clothes feeding opening 21 are provided with sliding grooves 23, and the left and right ends of the sliding cover 22 are slidingly arranged on the sliding grooves 23.

[0089] The sliding cover limiting device 6 includes a limiting part 61 and a limiting lock 62. The limiting part 61 is arranged on the sliding cover 22. The limiting lock 62 is arranged at the top of the housing 1 to block the outward movement of the sliding cover 22 in cooperation with the limiting part 61 during the outward extension of the drying drum 2, or to block the inward movement of the sliding cover 22 in cooperation with the limiting part 61 during the inward retraction of the drying drum 2.

[0090] The limiting lock 62 includes a telescopic lock tongue that extends into the limiting part 61 when the drying drum 2 starts to extend outward, or retracts when the drying drum 2 starts to rotate in the housing 1.

[0091] The slide cover 22 is arranged on the drying drum 2 in a sliding manner along the axial direction of the drying drum 2. The slide cover 22 has two working positions, i.e., a first working position and a second working position. The first working position is a position where the drying drum 2 is completely retracted into the shell 1 and the slide cover 22 closes the clothes feeding opening 21. The second working position is a position where the front end of the slide cover 22 moves into the opening 11 along with the drying drum 2 and opens the clothes feeding opening 21.

[0092] The preset distance is a distance between the first working position and the second working position of the slide cover 22.

[0093] Specifically, when the slide cover 22 moves outward into the opening 11 along with the drying drum 2, the locking tongue of the limiting lock 62 cooperates with the limiting portion 61 to stop the slide cover 22 from moving outward, and the slide cover 22 is partially separated from the drying drum 2 to open the clothes feeding opening 21. When the slide cover 22 moves inward into the shell 1 along with the drying drum 2, the locking tongue of the limiting lock 62 cooperates with the limiting portion 61 to stop the slide cover 22 from moving inward, and the drying drum 2 continues to move inward to move the clothes feeding opening 21 to a position opposite to the slide cover 22 and close the clothes feeding opening 21.

[0094] In the present application, the limiting portion 61 and the limiting lock 62 cooperate. When the slide cover 22 moves outward into the opening 11 along with the drying drum 2, the locking tongue of the limiting lock 62 extends into the limiting portion 61 to lock the slide cover 22 and stop the slide cover 22 from moving outward, and the slide cover 22 is partially separated from the drying drum 2 to open the clothes feeding opening 21. At this time, the front end of the slide cover 22 is located in the opening 11, and the rear end of the slide cover 22 is supported on the drying drum 2, so that the slide cover 22 can maintain a state of balance between the front and the rear and will not fall along with the inward and outward movement of the drying drum 2.

[0095] Specifically, the limiting portion 61 includes a first limiting structure 611. The first limiting structure 611 is arranged on the slide cover 22 and located behind the locking tongue. The first limiting structure 611 is used to abut against the extending locking tongue during the outward movement of the slide cover 22 along with the drying drum 2, block the slide cover 22 from continuously moving outward, and make the drying drum 2 continuously move outward to separate the slide cover 22 from the drying drum 2 and open the clothes feeding opening 21.

[0096] The limiting portion 61 further includes a second limiting structure 612 arranged on the slide cover 22. The second limiting structure 612 is located in front of the locking tongue and is used to abut against the locking tongue during the inward retraction of the drying drum 2, block the slide cover 22 from continuously moving inward, and make the drying drum 2 continuously move inward to make the slide cover 22 close the clothes feeding opening 21.

[0097] The second limiting structure 612 and the first limiting structure 611 are arranged on the sliding cover 22 in an axial direction from front to back at a preset distance.

[0098] The first limiting structure 611 and the second limiting structure 612 are matched to make the sliding cover 22 move within the preset distance, so that the sliding cover 22 will not fall off from the drying drum 2, and the structure is simple and low in cost.

[0099] In a specific embodiment, the outer side wall of the sliding cover 22 protrudes from the outer peripheral wall of the drying drum 2. The inner edge of the inner side of the opening 11 is provided with a clearance. The outer side wall of the sliding cover 22 protrudes radially from the inner edge of the outer side of the opening 11. The second limiting structure 612 is the outer side wall protruding from the front end of the sliding cover 22, which moves to the clearance during the movement of the drying drum 2 outward, so that the inner edge of the inner side of the opening 11 can block the front end of the sliding cover 22 from being raised upward, and the inner edge of the outer side of the opening 11 can block the sliding cover 22 from moving outward continuously.

[0100] In another specific embodiment, the first limiting structure 611 and the second limiting structure 612 are two limiting protrusions arranged on the sliding cover 22 in an axial direction of the drying drum 2, and a limiting channel is formed between the two limiting protrusions.

[0101] When the drying drum 2 starts to extend outward, the locking tongue extends into the limiting channel and slides in the limiting channel. When the locking tongue slides to the rear end of the limiting channel, the locking tongue abuts against the first limiting structure 611 to block the sliding cover 22 from moving outward continuously with the drying drum 2, so that the front end of the sliding cover 22 is separated from the clothes-throwing opening 21, and part of the clothes-throwing opening 21 is opened.

[0102] When the drying drum 2 retracts inward, the locking tongue slides in the limiting channel, and the position of the sliding cover 22 relative to the drying drum 2 is unchanged. When the locking tongue slides to the front end of the limiting channel, the locking tongue abuts against the second limiting structure 612 to block the sliding cover 22 from moving backward continuously with the drying drum 2, so that the drying drum 2 moves backward relative to the sliding cover 22. When the drying drum 2 is completely retracted into the shell 1, the sliding cover 22 completely closes the clothes-throwing opening 21.

[0103] The sliding cover 22 is an arc-shaped plate arranged along a circumferential direction of the drying drum 2.

[0104] Preferably, the clothes-throwing opening 21 of the present application extends to the rear wall of the drying drum 2, and when the drying drum 2 is extended outwards, the sliding cover 22 is stopped by the sliding cover 22 stopper 6, and the drying drum 2 continues to extend outwards, so that the sliding cover 22 can smoothly pass the rear end of the clothes-throwing opening 21, and the clothes-throwing opening 21 is opened.

[0105] Further, the drying machine further comprises a driving motor 9 and a control assembly.

[0106] The driving motor 9 is arranged on the rear side of the frame 3. The driving motor 9 is in transmission connection with the rear end of the drying drum 2 through a rotating shaft, for driving the drying drum 2 to rotate. The control assembly is used for receiving a drying drum 2 extension or retraction signal, controlling the driving motor 9 to stop at a preset position of the stopper 61 towards the stopper lock 62, and controlling the automatic extension and retraction device 4 to drive the drying drum 2 to extend outwards or retract inwards.

[0107] As shown in the drawings, the control assembly comprises a position detection module 7, a locking module 8 and a control module (not shown in the drawings). Fig. 3

[0108] The position detection module 7 is used for detecting whether the drying drum 2 rotates to a preset position. The locking module 8 is used for locking the drying drum 2 in the rotating direction. The control module is in communication connection with the position detection module 7, the locking module 8 and the automatic extension and retraction device 4, respectively, and is used for receiving a signal detected by the position detection module 7 that the drying drum 2 rotates to the preset position, sending a drying drum 2 locking signal to the locking module 8 to lock the drying drum 2, and then sending a driving signal to the automatic extension and retraction device 4 to drive the drying drum 2 to extend outwards.

[0109] The preset position is a position where the stopper 61 is towards the stopper lock 62, i.e. a position where the clothes-throwing opening 21 is upwards.

[0110] When the drying machine receives an instruction to extend the drying drum 2, the position detection module 7 detects whether the drying drum 2 rotates to a preset position where the stopper 61 on the sliding cover 22 is upwards and opposite to the stopper lock 62. If it is detected that the drying drum 2 rotates to the preset position, a signal is sent to the control module, and the control module sends a locking signal to the locking module 8 to lock the drying drum 2 in the rotating direction, to prevent the drying drum 2 from rotating during the extension process.

[0111] ​Then, the lock tongue of the slide cover limiting device 6 is controlled to extend downward between the first limiting structure 611 and the second limiting structure 612, and the automatic telescopic device 4 drives the drying drum 2 to move outward. When the drying drum 2 moves a preset distance, the lock tongue abuts against the first limiting structure 611, thereby blocking the slide cover 22 from moving outward, and the drying drum 2 continues to move outward, so that the clothes feeding opening 21 is automatically opened and the user can take or put clothes from the upper part of the drying drum 2.

[0112] When the drying machine receives the retraction instruction of the drying drum 2, the automatic telescopic device 4 drives the drying drum 2 to move the slide cover 22 inward. When the drying drum 2 moves to the position where the lock tongue abuts against the second limiting structure 612, the slide cover 22 is blocked from moving inward, and the drying drum 2 continues to move inward, so that the clothes feeding opening 21 is gradually closed by the slide cover 22.

[0113] Then, the lock tongue of the slide cover limiting device 6 is controlled to retract upward, the locking module 8 is unlocked in the rotating direction, and the drying machine can operate to dry clothes.

[0114] The position detection module 7 comprises a signal generating unit 71 and a signal receiving unit 72.

[0115] The signal generating unit 71 is rotatably arranged on the drying drum 2 or the driving motor 9. The signal receiving unit 72 is arranged on the shell 1 or the frame 3 outside the periphery of the signal generating unit 71. The signal receiving unit 72 is connected with the control module and is used to receive the signal generated by the signal generating unit 71 when the signal generating unit 71 is close to the signal receiving unit 72, and send the signal that the drying drum 2 is in position to the control module.

[0116] The locking module 8 comprises a locking hole 81 and a locking device 82.

[0117] The locking hole 81 is arranged on the rotor of the driving motor 9. The locking device 82 is arranged on the frame 3 outside the periphery of the locking hole 81. The locking device 82 comprises a lock rod which is driven to be retractable. The locking device 82 is connected with the control module and is used to receive the locking signal of the control module to drive the lock rod to extend into the locking hole 81 to be locked.

[0118] Further, the drying machine further comprises a condensing module, an auxiliary condensing module and a lint filter module.

[0119] The condensing module and the auxiliary condensing module are arranged in the shell 1 below the drying drum 2. The lint filter is arranged on the front side of the drying machine and is located in the front side plate 12 below the drum opening of the drying drum 2.
