[0108] The limiting lock 71 includes a retractable locking tongue 711 which is extended into the limiting part 72 when the drying drum 2 starts to move outward or is retracted when the drying drum 2 starts to rotate in the shell 1.

[0109] The sliding cover 22 is slidingly arranged on the drying drum 2 along the axis of the drying drum 2. The sliding cover 22 has two working positions, i.e., a first working position and a second working position.

[0110] The first working position is the position when the drying drum 2 is completely retracted into the casing 1 and the slide cover 22 closes the drum opening 21. The second working position is the position when the front end of the slide cover 22 moves into the opening 11 along with the drying drum 2, and the drum opening 21 is opened.

[0111] The preset distance is the distance between the first working position and the second working position of the slide cover 22.

[0112] Specifically, when the slide cover 22 moves outward into the opening 11 along with the drying drum 2, the locking tongue 711 of the limiting lock 71 cooperates with the limiting portion 72 to stop the slide cover 22 from moving outward, and the slide cover 22 partially separates from the drying drum 2 to open the drum opening 21.

[0113] In the present application, the limiting portion 72 cooperates with the limiting lock 71. When the slide cover 22 moves outward into the opening 11 along with the drying drum 2, the locking tongue 711 of the limiting lock 71 extends into the limiting portion 72, locks the slide cover 22 to stop it from moving outward, and partially separates from the drying drum 2 to open the drum 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.

[0114] As shown in Figure 2 , Figure 3 and Figure 6 , one embodiment is that the limiting portion 72 comprises a first limiting structure 721. The first limiting structure 721 is arranged on the slide cover 22 and located behind the locking tongue 711, and is used to abut against the extending locking tongue 711 during the outward movement of the slide cover 22 along with the drying drum 2, to block the slide cover 22 from continuously moving outward, while the drying drum 2 continuously moves outward, so that the slide cover 22 separates from the drying drum 2 to open the drum opening 21.

[0115] Further, the limiting portion 72 further comprises a second limiting structure 722 arranged on the slide cover 22. The second limiting structure 722 is located in front of the locking tongue 711, and is used to abut against the locking tongue 711 during the inward retraction of the drying drum 2, to block the slide cover 22 from continuously moving inward, while the drying drum 2 continuously moves inward, so that the slide cover 22 closes the drum opening 21.

[0116] The second limiting structure 722 and the first limiting structure 721 are arranged on the slide cover 22 in an axial direction from front to back.

[0117] The first limiting structure 721 and the second limiting structure 722 are matched, so that the slide cover 22 moves within a preset distance, and the slide cover 22 cannot fall off from the drying drum 2, and the structure is simple and low in cost.

[0118] In a specific embodiment, the outer side wall of the slide 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 avoiding opening. The outer side wall of the slide cover 22 protrudes radially from the inner edge of the outer side of the opening 11. The second limiting structure 722 is the outer side wall protruding from the front end of the slide cover 22, which moves into the avoiding opening during the outward movement of the drying drum 2. The inner edge of the inner side of the opening 11 can block the front end of the slide cover 22 from being raised upward, and the inner edge of the outer side of the opening 11 can block the slide cover 22 from continuing to move outward.

[0119] In another specific embodiment, the first limiting structure 721 and the second limiting structure 722 are two limiting protrusions arranged on the slide cover 22 along the axial direction of the drying drum 2, and a limiting channel is formed between the two limiting protrusions.

[0120] When the drying drum 2 starts to extend outward, the lock tongue 711 extends into the limiting channel and slides in the limiting channel. When the lock tongue 711 slides to the rear end of the limiting channel, the lock tongue 711 abuts against the first limiting structure 721, thereby blocking the slide cover 22 from continuing to move outward with the drying drum 2, and the front end of the slide cover 22 is separated from the drum opening 21, and part of the drum opening 21 is opened.

[0121] When the drying drum 2 is retracted inward, the lock tongue 711 slides in the limiting channel, and the position of the slide cover 22 relative to the drying drum 2 does not change. When the lock tongue 711 slides to the front end of the limiting channel, the lock tongue 711 abuts against the second limiting structure 722, thereby blocking the slide cover 22 from continuing to move backward with the drying drum 2, and the drying drum 2 moves backward relative to the slide cover 22. When the drying drum 2 is completely retracted into the shell 1, the slide cover 22 completely closes the drum opening 21.

[0122] In another specific embodiment, the limiting part 72 is a limiting channel groove arranged on the slide cover 22 in the axial direction of the drying drum 2. The lock tongue 711 can extend into the limiting channel groove.

[0123] The limiting lock 71 further comprises a lock body 712. The lock body 712 is arranged on the top wall of the shell 1. The lock body 712 is connected with the lock tongue 711 and is used to drive the lock tongue 711 to extend and retract upward and downward.

[0124] The preset distance is equal to the distance between the first limiting structure 721 and the second limiting structure 722, so that the front end of the sliding cover 22 can reach the opening 11 during the extension of the drying drum 2, ensuring the stability of the sliding cover 22 during the extension and retraction of the drying drum 2.

[0125] As shown in the drawings, another embodiment is that the limiting part 72 comprises a limiting groove 723. Figures 7 to 9

[0126] The limiting groove 723 is arranged on the sliding cover 22. The lock tongue 711 is arranged to be reciprocally movable along the axial direction of the drying drum 2. The lock tongue 711 is used to extend into the limiting groove 723 to limit the sliding of the sliding cover 22 within the reciprocating movement of the lock tongue 711 when the drying drum 2 extends outward, or to retract from the limiting groove 723 when the drying drum 2 rotates in the housing 1.

[0127] The limiting groove 723 is matched with the lock tongue 711. The sliding cover 22 is provided with a convex column, and the limiting groove 723 is arranged in a recessed manner on the convex column.

[0128] When the drying drum 2 starts to extend outward, the lock tongue 711 is located at the rear end of the movable range and extends into the limiting groove 723. The drying drum 2 starts to extend outward and drives the lock tongue 711 to move forward. When the lock tongue 711 moves to the front end of the movable range, the lock tongue 711 blocks the sliding cover 22 from continuing to move outward with the drying drum 2, so that the front end of the sliding cover 22 is separated from the barrel opening 21, and part of the barrel opening 21 is opened.

[0129] When the drying drum 2 retracts inward, the position of the sliding cover 22 relative to the drying drum 2 is unchanged, and the sliding cover 22 and the lock tongue 711 are driven to move backward. When the lock tongue 711 moves to the rear end of the movable range of the lock tongue 711, the lock tongue 711 blocks the sliding cover 22 from continuing to move backward 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 housing 1, the sliding cover 22 closes the barrel opening 21.

[0130] The limiting lock 71 comprises a mounting part 713 and a lock body 712.

[0131] The mounting part 713 is arranged on the top wall in the housing 1. The lock body 712 is arranged to be reciprocally movable along the axial direction on the mounting part 713. The lock body 712 is connected with the lock tongue 711 and is used to drive the lock tongue 711 to extend and retract upward and downward.

[0132] The preset distance is equal to the reciprocating movement distance of the lock tongue 711, so that the front end of the sliding cover 22 can reach the opening 11 during the extension of the drying drum 2, ensuring the stability of the sliding cover 22 during the extension and retraction of the drying drum 2. ​

[0133] As Figures 1 to 2 shown, the barrel opening 21 extends rearward from the peripheral wall of the drying barrel 2 to the rear wall of the drying barrel 2.

[0134] The barrel opening 21 of the present application extends rearward to the rear wall of the drying barrel 2. When the drying barrel 2 is extended outward, the slide cover 22 is stopped by the slide cover limiting device 7, and the drying barrel 2 continues to extend outward, so that the slide cover 22 can smoothly pass the rear end of the barrel opening 21, and open the barrel opening 21.

[0135] The slide cover 22 is an arc-shaped plate arranged along the circumferential portion of the drying barrel 2. The two front and rear extending edges of the arc-shaped plate are respectively slidably installed on the left and right side edges of the barrel opening 21, so that the barrel door cover can be conveniently slid forward and backward relative to the barrel opening 21.

[0136] The two left and right extending edges of the arc-shaped plate are respectively buckled on the front side edge of the barrel opening 21 and the partial outer circumferential edge of the rear wall of the drying barrel 2. When the drying barrel 2 is extended outward, the arc-shaped plate can pass the partial outer circumferential edge of the rear wall of the drying barrel 2, and partially disengage from the barrel opening 21.

[0137] The two front and rear extending edges of the barrel opening 21 are respectively provided with a sliding groove 23 extending in the front and rear directions, and the left and right sides of the slide cover 22 are respectively installed on the two sliding grooves 23, so as to improve the smoothness of the slide cover 22 in opening and closing the barrel opening 21.

[0138] The control assembly is used to control the drying barrel 2 to stop rotating at a position opposite to the limiting portion 72 relative to the limiting lock 71.

[0139] Further, the clothes dryer further comprises a condensing module and a lint filter module.

[0140] The condensing module is arranged in the housing 1 below the drying barrel 2. The lint filter is arranged on the front side of the clothes dryer, below the clothes feeding opening on the front side plate 6.

[0141] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent.
