[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] See also Figure 1 and Figure 2The present embodiment provides an inner drum device of a drum washing machine, comprising an inner drum 100, a lifting rib assembly 200 and a roller brush assembly 300. The lifting rib assembly 200 comprises a housing 210, the housing 210 is connected to the inner wall of the inner drum 100 along the axial direction of the inner drum 100, and the top of the housing 210 has an escape opening 211 arranged along the length direction of the housing 210. The roller brush assembly 300 comprises a roller brush 310, the roller brush 310 is rotatably connected to the housing 210 and is arranged at the escape opening 211 along the length direction of the housing 210, and the roller brush 310 can contact the clothes in the inner drum 100.

[0049] The drum washing machine inner drum device is provided with a avoidance opening 211 on the housing 210 of the lifting rib assembly 200, so that a roller brush 310 can be provided at the avoidance opening 211. During the operation of the washing machine, the clothes rotate along with the inner drum 100, and the lifting rib assembly 200 contacts the clothes and brings the clothes to a high place. At the same time, the roller brush 310 contacts the clothes and rotates during the friction with the clothes, thereby removing the hair scraps on the clothes. Since the roller brush 310 directly contacts the clothes, the hair scraps on the clothes can be removed regardless of whether there is washing water in the inner drum 100, and a good hair scraps removal effect is achieved.

[0050] Continue to see Figure 1 and Figure 2 In this embodiment, the shell 210 is a strip-shaped hard structure extending along the axial direction of the inner cylinder 100, and its cross-sectional shape in the radial direction of the inner cylinder 100 is approximately an isosceles trapezoid, and the width of the top of the shell 210 (the part close to the central axis of the inner cylinder 100) is smaller than the width of the bottom (the part away from the central axis of the inner cylinder 100). Optionally, the number of lifting rib assemblies 200 can be set to three, and the three lifting rib assemblies 200 are arranged at equal intervals along the inner wall of the inner cylinder 100.

[0051] Since the housing 210 is provided with a clearance opening 211 at the top, a mounting groove for the roller brush assembly 300 is formed inside. In this embodiment, most of the roller brush 310 is located below the clearance opening 211, and the remaining part is exposed from the clearance opening 211 and is higher than the top of the housing 210, thereby ensuring that the roller brush 310 can contact the clothes. It can be understood that when washing clothes, the clothes rotate clockwise or counterclockwise with the drum, so the central axis of the roller brush 310 is arranged parallel to the central axis of the inner drum 100, and when rubbing with the clothes, it rotates clockwise or counterclockwise with the clothes.

[0052] Further, see Figure 1The shell 210 includes a first shell wall 212 and a second shell wall 213 located on both sides of the length direction of the roller brush 310. A first cleaning component 410 is arranged on the inner side of the first shell wall 212, and a second cleaning component 420 is arranged on the inner side of the second shell wall 213. When the roller brush 310 rotates, the first cleaning component 410 or the second cleaning component 420 can make the hair debris on the roller brush 310 fall into the interior of the shell 210.

[0053] It can be understood that since the rotation direction of the roller brush 310 is clockwise and counterclockwise, during the rotation of the roller brush 310, one of the two cleaning components should allow the roller brush 310 to rotate with hair debris, and the other should be able to make the hair debris fall off the roller brush 310 and fall into the interior of the shell 210.

[0054] Exemplarily, the first cleaning component 410 and the second cleaning component 420 both include a fixed plate 401 and cleaning bristles 402, the fixed plate 401 is connected to the inner side of the first shell wall 212 or the second shell wall 213, the cleaning bristles 402 are connected to the fixed plate 401, the cleaning bristles 402 and the fixed plate 401 are connected at an angle, and the free ends of the cleaning bristles 402 extend toward the bottom of the shell 210.

[0055] Optionally, the fixing plate 401 may be a rectangular plate-shaped structure, and its length is set according to the length of the roller brush 310. The installation positions of the first cleaning component 410 and the second cleaning component 420 should satisfy the spatial overlap between the cleaning bristles 402 and the roller brush 310, so that the cleaning bristles 402 can play a role in brushing away hair scraps. Figure 1 As shown, the cleaning bristles 402 and the fixing plate 401 are connected at an angle, and the free ends of the cleaning bristles 402 extend toward the bottom of the housing 210, so that when the roller brush 310 rotates counterclockwise, the cleaning bristles 402 on the first cleaning component 410 will not prevent hair debris from entering the interior of the housing 210. When the roller brush 310 continues to rotate with hair debris until it contacts the cleaning bristles 402 on the second cleaning component 420, the cleaning bristles 402 are tilted downward, so that the hair debris on the roller brush 310 can be brushed off, and then the hair debris remains in the interior of the housing 210. Similarly, when the roller brush 310 rotates clockwise, the cleaning bristles 402 on the second cleaning component 420 will not prevent hair debris from entering the interior of the housing 210. When the roller brush 310 continues to rotate with hair debris until it contacts the cleaning bristles 402 on the first cleaning component 410, the hair debris is brushed off by the cleaning bristles 402 and remains in the interior of the housing 210.

[0056] Further, see Figure 2The roller brush assembly 300 also includes a connecting shaft 320, and the roller brush 310 includes a first roller 311 and a second roller 312. The connecting shaft 320 is arranged along the length direction of the avoidance opening 211 and both ends are rotatably connected to the shell 210. The first roller 311 and the second roller 312 are both fixedly sleeved on the connecting shaft 320. The first roller 311 and the second roller 312 are provided with roller brush bristles 313 with opposite rotation directions. When the roller brush 310 rotates forward, the roller brush bristles 313 on the first roller 311 collect hair scraps. When the roller brush 310 rotates reversely, the roller brush bristles 313 on the second roller 312 collect hair scraps.

[0057] Optionally, mounting holes are provided at both ends of the housing 210, and the connecting shaft 320 can be rotatably passed through the mounting holes. Bushings 314 are provided at both ends of the connecting shaft 320, and the bushings 314 are used to reduce friction, thereby facilitating the rotation of the connecting shaft 320 in the mounting holes.

[0058] In order to prevent clothes from getting tangled, the washing machine needs to rotate forward and reverse alternately during operation. In order for the lifting rib assembly 200 to collect hair scraps during both forward and reverse rotations, roller brush bristles 313 with different rotation directions are provided on the first roller 311 and the second roller 312. For example, the roller brush bristles 313 on the first roller 311 rotate counterclockwise, and the roller brush bristles 313 on the second roller 312 rotate clockwise. When the inner drum 100 rotates clockwise, the roller brush bristles 313 on the second roller 312 collect hair scraps, Figure 1 The cleaning bristles 402 of the first cleaning assembly 410 on the left side are shown to separate hair scraps; when the inner cylinder 100 rotates counterclockwise, the roller brush bristles 313 on the first roller 313 collect hair scraps, Figure 1 The cleaning bristles 402 of the second cleaning assembly 410 shown on the right side separate the hair scraps. In the present embodiment, the first roller 311 and the second roller 312 are respectively provided with one, and in other embodiments, the number of the first roller 311 can be two, three or four, etc., and the number of the second rollers 312 is equal to the number of the first rollers 311, so that the hair scraps can be collected in the same length when the inner cylinder 100 rotates forward and reverse. Optionally, when the number of the first roller 311 and the second roller 312 is multiple, the first roller 311 and the second roller 312 can be alternately arranged along the length direction of the connecting shaft 320. Of course, the roller brush bristles 313 with different rotation directions can also be arranged on the same roller at the same time, and the specific arrangement can be made according to the use needs.

[0059] Furthermore, the roller brush assembly 300 also includes a driving ring 330, which is fixedly sleeved on the connecting shaft 320, and driving teeth 331 are arranged along the outer circumference of the driving ring 330. The rotating clothes contact the driving teeth 331 to drive the connecting shaft 320 to rotate.

[0060] Optionally, the driving teeth 331 may be made of flexible rubber or silicone material. Optionally, there may be a plurality of driving rings 330 , and the plurality of driving rings 330 are arranged on the connecting shaft 320 at intervals.

[0061] Further, see Figures 1 to 3 The shell 210 includes a bottom plate 214 located at the bottom, the bottom plate 214 is connected to the inner wall of the inner drum 100, and a water filter hole 2141 is provided on the bottom plate 214, and the water filter hole 2141 is used to discharge the washing water inside the shell 210.

[0062] Optionally, the bottom plate 214 is a detachable structure. The bottom plate 214 is detachably connected to the inner wall of the inner drum 100, and the lifting rib assembly 200 can be easily removed when cleaning is required. Furthermore, the bottom plate 214 is detachably connected to the first shell wall 212 and the second shell wall 213. After removing the bottom plate 214, a large amount of hair debris can be seen. After pouring out the hair debris, rinse the inside of the shell 210 with water, and install the lifting rib assembly 200 back into the inner drum 100 after cleaning. By providing a water filter hole 2141 on the bottom plate 214, the washing water inside the shell 210 can flow out from the water filter hole 2141, effectively preventing the breeding of bacteria and the generation of odor.

[0063] Further, see Figure 3 A wall flap 2142 is provided in the water filter hole 2141, and the wall flap 2142 is used to block the water filter hole 2141 and can open the water filter hole 2141 under the action of centrifugal force.

[0064] Optionally, the wall flap 2142 is made of silicone or rubber, and a cross-shaped cutout is provided in the center. When static, the cutout is closed and the washing water cannot flow out. When subjected to a large centrifugal force, the wall flap 2142 opens at the cutout to allow water to flow out. Figure 4 In order to facilitate the opening of the wall petal 2142, a pit is set at the bottom or top of the incision, so that the central part of the wall petal 2142 is thinner and it is easier to open the incision during dehydration.

[0065] See also Figure 5 A water hole 130 is provided on the inner drum 100, and the interior of the shell 210, the water filter hole 2141 and the water hole 130 are connected in sequence, and the washing water inside the shell 210 can be discharged through the water filter hole 2141 and the water hole 130 in sequence.

[0066] By providing the water hole 130 on the inner drum 100, the washing water flowing out of the water filter hole 2141 can be discharged from the water hole 130 during dehydration. It can be understood that the water hole 130 is located below the bottom plate 214. Preferably, the water hole 130 and the water filter hole 2141 are arranged opposite to each other, so as to facilitate the discharge of washing water.

[0067] Furthermore, the lifting rib assembly 200 also includes a clamping structure 220 arranged at the bottom of the shell 210, and a clamping groove 110 is arranged on the inner cylinder 100. The clamping structure 220 and the clamping groove 110 can be conveniently disassembled and clamped.

[0068] By using the clamping structure 220 to detachably connect the lifting rib assembly 200 and the inner cylinder 100, when it is necessary to clean the hair inside the shell 210, the lifting rib assembly 200 can be removed from the inner cylinder 100, and after cleaning, it can be put back in place. In other embodiments, the lifting rib assembly 200 can also be fixedly connected to the inner wall of the inner cylinder 100 or detachably connected using other connection structures. In this embodiment, four groups of clamping structures 220 are provided, which are respectively located at the four corners of the bottom of the shell 210, and correspondingly, four clamping slots 110 are provided. In other embodiments, the number of clamping structures 220 is set according to the use needs, and the number of clamping slots 110 is set according to the clamping structures 220.

[0069] Furthermore, in this embodiment, the snap-fit ​​structure 220 includes a guide cap 221, and the snap-fitting slot 110 includes an insertion slot 111, a guide slot 112 and a locking slot 113 which are connected in sequence, and the guide slot 112 and the locking slot 113 are arranged at an angle, and the guide cap 221 can penetrate into the insertion slot 111, pass through the guide slot 112, enter the locking slot 113 and snap into the locking slot 113.

[0070] See also Figure 5 and Figure 6 The guide cap 221 is a hemispherical structure with its center protruding toward the bottom plate 214. The insertion groove 111 has a circular opening, and the guide cap 221 can enter the insertion groove 111. The width of the guide groove 112 and the locking groove 113 is smaller than the diameter of the insertion groove 111 and smaller than the outer diameter of the guide cap 221, so that the guide cap 221 cannot exit from the guide groove 112 and the locking groove 113 after entering the guide groove 112 and the locking groove 113.

[0071] Further, see Figure 6 The clamping structure 220 also includes a screw 222, which passes through the guide cap 221 and is threadedly connected to the housing 210. An elastic member 223 is sleeved on the screw 222, and two ends of the elastic member 223 are respectively abutted against the guide cap 221 and the head of the screw 222.

[0072] The guide cap 221 and the housing 210 are fixed by screws 222 , and a spring is provided to ensure that the guide cap 221 can be inserted into the locking groove 113 and can be tightly abutted against the inner cylinder 100 , thereby ensuring the stability of the connection.

[0073] Further, see Figure 2 The shell 210 also includes a reinforcement structure 230 located at both ends of the roller brush 310 .

[0074] Optionally, the reinforcement structure 230 includes two side plates perpendicular to the bottom plate 214 and two inclined plates arranged at an acute angle to the bottom plate 214. By adopting the double-layer plate arrangement, the overall structural strength of the shell 210 is increased.

[0075] Further, see Figure 2 and Figure 6 An abutment plate 120 is provided on the inner cylinder 100, and the reinforcing structure 230 has a cavity 231 opened toward the inner cylinder 100. A compression spring 232 is provided in the cavity 231. One end of the compression spring 232 is connected to the inner wall of the cavity 231. After the clamping structure 220 enters the locking groove 113, the other end of the compression spring 232 abuts against the abutment plate 120.

[0076] The cavity 231 is provided to provide space for the installation of the compression spring 232. Since the stiffness of the reinforcement structure 230 is relatively large, the clamping structure 220 is installed at the bottom of the reinforcement structure 230. It can be understood that the position of the compression spring 232 on the bottom plate 214 is set according to the position of the abutment plate 120 on the inner cylinder 100 to ensure that the two can abut against each other, thereby preventing the housing 210 from moving in the length direction.

[0077] When assembling the lifting rib assembly 200 and the inner cylinder 100, the lifting rib assembly 200 is placed at a position roughly corresponding to the inner cylinder 100, one of the guide caps 221 is aligned with the insertion groove 111 and inserted, and then the lifting rib assembly 200 is rotated to make the other three guide caps 221 also enter the insertion groove 111, and the lifting rib assembly 200 is pulled along the extension direction of the guide groove 112. At this time, the compression spring 232 and the abutment plate 120 abut and are gradually compressed. When the guide cap 221 enters the locking groove 113, the guide cap 221 is fixed at the end of the locking groove 113 under the restoring force of the compression spring 232. Since the lifting rib assembly 200 is almost not subjected to axial force during the rotation of the inner cylinder 100, it is almost impossible for it to fall off from the inner cylinder 100 without human operation.

[0078] Further, see Figure 7 A protrusion 2143 is provided at the bottom of the bottom plate 214 , and the protrusion 2143 abuts against the inner wall of the inner tube 100 .

[0079] In order to prevent the washing water from being unable to be discharged when the water hole 130 and the water filter hole 2141 are not aligned, a protrusion 2143 is provided at the bottom of the bottom plate 214, so that there is a certain gap between the bottom plate 214 and the inner drum 100, instead of being close to each other. Optionally, the protrusion 2143 can be strip-shaped, columnar or hemispherical, which is not specifically limited here.

[0080] See also Figure 8The drum washing machine also includes the above-mentioned drum washing machine inner drum device and a body 500, and the drum washing machine inner drum device is arranged in the body 500.
