Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically to a drum tipping mechanism for a drum washing machine. Background Technology

[0002] Trash cans are daily necessities, especially in public areas. After use, stains often remain on their inner and outer walls, requiring regular collection and cleaning to reduce their environmental impact. Cleaning machines play a crucial role in this process. To prevent water accumulation inside the can after cleaning, an additional step of turning the can over is usually added before washing, by placing the trash can upside down with the opening facing downwards.

[0003] For example, the patent CN119368529A discloses "an intelligent cleaning machine and cleaning method for cleaning trash cans", which adopts a four-station circular layout and synchronous turntable structure. The trash cans are automatically flipped and fed through the cooperation of the upper and lower bin mechanism, the elastic support mechanism and the rotating bracket. The conveying mechanism drives the trash cans to enter the foam, cleaning and disinfection drying stations in sequence. Each station can operate in parallel, improving the overall processing continuity. However, the bin loading and unloading mechanism remains connected to the trash can throughout the subsequent process and cannot be detached, which will have a certain impact on the cleaning effect and efficiency of the trash can. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a drum-tilting mechanism for a drum washing machine to solve the aforementioned problems.

[0005] This invention provides the following technical solution: A drum-tilting mechanism for a drum washing machine, comprising: A support frame, which is driven to flip around its upper part by a tilting bucket assembly; The bin-hanging assembly, located on the upper part of the support frame, includes a bin-hanging base, bin-hanging teeth fixed on the bin-hanging base, and a bin-hanging movable base rotatably connected to the bin-hanging base. The bin-hanging movable base is provided with an L-shaped pressure plate. The L-shaped pressure plate is flipped to press the garbage bin tightly against the support frame, and the bin-hanging teeth are used to hang the eaves of the garbage bin. The bin-retrieving assembly, located on the side wall of the support frame, is used to adhere and secure the trash can after it has been cleaned.

[0006] Preferably, a first telescopic component is installed on the hanging bucket fixing seat, and the telescopic end of the first telescopic component is connected to the hanging bucket movable seat to drive the L-shaped pressure plate to perform a flipping action.

[0007] Preferably, the hanging teeth are L-shaped, with the vertical ends of the L-shaped hanging teeth facing upwards and inserted into the eaves of the trash can.

[0008] Preferably, the bucket retrieval assembly includes a bucket retrieval fixed base and a bucket retrieval movable base rotatably connected to the bucket retrieval fixed base, wherein a set of one or more suction cups are installed on the bucket retrieval movable base.

[0009] Preferably, a second telescopic component is installed on the bucket-retrieving fixed base, and the telescopic end of the second telescopic component is connected to the bucket-retrieving movable base.

[0010] Preferably, the suction cup is mounted on the bucket-retrieving movable seat via a corresponding elastic telescopic rod.

[0011] The present invention has the following beneficial technical effects: This invention allows trash cans to be placed upside down into a trash can washing machine, enabling automation—automatic entry and automatic retrieval. After the trash can is tipped into the washing machine, it can detach from the tipping mechanism, providing a solution for washing trash cans on assembly lines and rotating platforms. This avoids the trash can being unable to detach from the tipping mechanism, which could affect subsequent washing processes.

[0012] The bucket-tilting mechanism of this invention can be installed independently and is compatible with various types of bucket washing machines. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example: A drum washing machine uses a drum tipping mechanism 300, such as Figures 1-6 As shown, it includes a support frame 31, a bucket hanging assembly 32, a bucket retrieval assembly 33, and a bucket tipping assembly 34; The tipping bucket assembly 34 is fixedly set. The tipping bucket assembly 34 can be a geared motor. The output end of the geared motor is connected to the rotation shaft of the support frame 31, so that the tipping bucket assembly 34 drives the support frame 31 to tip.

[0017] like Figure 1 As shown, under normal conditions, the rotation axis of the support frame 31 is located at its upper part.

[0018] like Figure 4 As shown, the bucket hanging assembly 32 includes a bucket hanging base 321, a bucket hanging movable base 322, a pressure plate 323, a bucket hanging tooth 324, and a first telescopic assembly (not shown in the figure). The bucket hanging base 321 is fixed to the upper part of the support frame 31, and the bucket hanging movable base 322 is hinged to the upper end of the bucket hanging base 321. The bucket hanging tooth 324 has an L-shaped structure, with the horizontal end of the bucket hanging tooth 324 fixed to the upper part of the support frame 31, and the vertical end of the bucket hanging tooth 324 facing upward relative to its horizontal end. The pressure plate 323 has an L-shaped structure, and its lateral end is fixed to the movable seat 322 of the hanging bucket. Figure 4 As shown, when clamping the trash can 200, the vertical ends of the pressure plate 323 are set facing downwards; The first telescopic component can be a telescopic cylinder. The fixed end of the first telescopic component is hinged to the bucket fixing seat 321, and the telescopic end of the first telescopic component is hinged to the bucket movable seat 322. Thus, the telescopic extension of the first telescopic component pushes the bucket movable seat 322 to rotate relative to the bucket fixing seat 321 within a 90° range.

[0019] Under normal circumstances Figure 1As shown, the bucket-retrieving assembly 33 is mounted opposite to the middle of the outer side wall of the support frame 31, as... Figure 5 As shown, the bucket retrieval assembly 33 includes a bucket retrieval fixing base 331, a second telescopic assembly 332, a bucket retrieval movable base 333, an elastic telescopic rod 334, and a suction cup 335; The bucket-retrieving fixing seat 331 is fixed to the middle of the outer side wall of the support frame 31. The bucket-retrieving movable seat 333 is hinged to the lower end of the bucket-retrieving fixing seat 331. The suction cup 335 is a vacuum suction cup. The suction cup 335 is installed on the bucket-retrieving movable seat 333 through the elastic telescopic rod 334. The suction cup 335 is made of rubber and other materials and has a certain elastic deformation ability.

[0020] The second telescopic component 332 can be a telescopic cylinder. The fixed end of the second telescopic component 332 is hinged to the bucket-retrieving fixed seat 331, and the telescopic end of the second telescopic component 332 is hinged to the bucket-retrieving movable seat 333. Thus, the telescopic extension of the second telescopic component 332 pushes the bucket-retrieving movable seat 333 to rotate relative to the bucket-retrieving fixed seat 331 within a 90° range.

[0021] Working principle: The drum tipping mechanism 300 is installed at the inlet / outlet 101 of the drum washing machine 100, such as... Figure 2 , Figure 3 As shown, the trash can 200 is pushed on the ground close to the inlet and outlet 101 of the washing machine 100, so that the trash can 200 fits against the support frame 31. At this time, the lid of the trash can 200 is located on the side away from the inlet and outlet 101 of the washing machine 100.

[0022] The process of placing the bucket includes four steps: hanging the bucket, flipping the bucket (in and out), lowering the bucket, and detaching. Hanging bucket: The first telescopic component extends and retracts, causing the pressure plate 323 to rotate as follows: Figure 4 As shown, this process is as follows Figure 7 As shown in A1 to A2, the vertical end of the pressure plate 323 presses against the inner wall of the trash can 200, thereby pressing the trash can 200 tightly against the side wall of the support frame 31. Flipping the bucket (in): The tipping assembly 34 drives the clamped trash can 200 to flip 180°, and this process is as follows: Figure 8 As shown in B1 to B2; after the trash can 200 is flipped 180°, its opening faces downward and it falls onto the conveyor belt platform of the bin washing machine 100.

[0023] Drop into the bucket: like Figure 9As shown, when the trash can 200 is flipped so that its opening faces downwards, it slides down a certain distance relative to the support frame 31 due to gravity, causing the trash can 200 to slide out relative to the vertical end of the hanging teeth 324, thus separating it. Simultaneously, the first telescopic component extends and retracts, causing the pressure plate 323 to rotate in the opposite direction and reset to its original position. Figure 9 As shown, the pressure plate 323 is separated from the trash can 200.

[0024] Afterwards, the conveyor belt platform of the washing machine 100 can move the trash can 200 to carry out subsequent cleaning steps such as foaming, washing, disinfection and drying, and finally return to the inlet and outlet 101 of the washing machine 100.

[0025] Detachment: like Figure 10 As shown, the first telescopic component extends and retracts, causing the pressure plate 323 to rotate 90°, so that the vertical end of the pressure plate 323 presses against the inner wall of the trash can 200, thereby pressing the trash can 200 tightly against the side wall of the support frame 31; at the same time, the second telescopic component 332 extends and retracts, causing the movable seat 333 to rotate 90° relative to the fixed seat 331. Figure 10 As shown, the suction cup 335 is oriented towards and adheres to the outer wall of the trash can 200, and the negative pressure of the suction cup 335 achieves adsorption and fixation to the outer wall of the trash can 200. The negative pressure of the suction cup 335 adsorbs the trash can 200, thus fixing the trash can 200 during the subsequent 180° rotation of the trash can 200 and preventing the trash can 200 from tilting.

[0026] Turning over the bucket (out): The tipping assembly 34 drives the support frame 31 to rotate 180° in the opposite direction, causing the trash can 200 to tip over out of the washing machine 100's door. After the trash can 200 lands, the suction cups 335 stop working and rotate 90° in the opposite direction to return to their original position and adhere to the support frame 31. The extension and retraction of the first telescopic assembly causes the pressure plate 323 to rotate 90° in the opposite direction, causing the pressure plate 323 to separate from the trash can 200.

[0027] Before hanging the bin, the rim of the bin 200 can be manually hung on the vertical end of the hanging teeth 324, or when the bin is flipped, after the bin 200 leaves the ground, it slides down a certain distance relative to the support frame 31 under the action of gravity, thereby automatically inserting the rim of the bin 200 into the vertical end of the hanging teeth 324.

[0028] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
