Description

Technical Field

[0001] This utility model relates to the field of washing machine drum technology, and in particular to a high-cleaning-efficiency washing machine drum. Background Technology

[0002] The washing machine drum is driven by a motor to rotate, causing the clothes to tumble continuously inside the drum. This generates centrifugal force and mixes water and detergent to form foam, which breaks down the structure of stains between the clothing fibers, thus thoroughly cleaning the clothes.

[0003] However, existing washing machine drums have a simple structure, resulting in low friction between clothes and the inner wall of the drum. This makes it impossible to beat the clothes during the washing process, and often causes clothes to tangle, resulting in low washing efficiency and cleaning rate. Utility Model Content

The outer drum is provided with a clothes cleaning mechanism to prevent clothes from tangling and a conical back cover mechanism. When washing clothes, the clothes cleaning mechanism will continuously bring the clothes to the highest point and then drop them. At the same time, the conical back cover mechanism will make the clothes stick tightly to the inner wall of the drum. The clothes cleaning mechanism includes an inner drum body movably installed inside the outer drum. Several sets of gem-shaped protrusions are evenly spaced on the inner side wall of the inner drum body. A first groove is opened between two adjacent sets of gem-shaped protrusions. A V-shaped rib assembly is fixedly installed on the inner wall of the inner drum body. Several circular through holes are opened through the outer side wall of the inner drum body. When the V-shaped rib assembly rotates with the inner drum body, it will bring the clothes to the highest point inside the drum and then drop them, thereby achieving the effect of patting the clothes.

[0006] Preferably, the V-shaped rib assembly has rectangular bosses symmetrically arranged on both sides, and a second groove is formed between two adjacent sets of rectangular bosses. The rectangular bosses and the second grooves are arranged alternately to form a unique clothing guiding path.

[0007] Preferably, the conical rear cover mechanism includes a rear cover reinforcing plate coaxially arranged with the outer roller, and a roller rear cover coaxially arranged on the inner cylinder body. The roller rear cover is movably connected to the rear cover reinforcing plate. The roller rear cover is provided with a first-level step and a second-level step. The first-level step and the second-level step are stamped together with the roller rear cover in one piece, which can effectively ensure the strength of the roller rear cover and avoid bending.

[0008] Preferably, the rotating shaft passes through the rear cover reinforcing plate and is fixedly connected to the rear cover of the drum. When the rotating shaft rotates, the rear cover of the drum and the inner cylinder will rotate synchronously.

[0009] Preferably, a drainage channel is provided between the outer roller and the inner cylinder, and water inside the inner cylinder can flow into the drainage channel through a circular through hole.

[0010] Preferably, the outer drum is equipped with a drain valve. During the washing process, the drain valve is initially closed. When the water level in the inner drum reaches a preset value, the drain valve will automatically open to release the water.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Existing washing machine drums have a simple structure, resulting in low friction between clothes and the drum's inner wall. This makes it impossible to effectively beat the clothes during washing, often leading to tangling and low washing efficiency and cleaning effectiveness. To address this technical deficiency in existing technologies, such as... Figures 1-5 As shown, this embodiment proposes a high-cleanliness drum for a drum washing machine, which can effectively prevent clothes from getting tangled inside the inner drum 301, and can also bring the clothes to the highest point inside the drum and then drop them during the washing process. The outer drum 1 of the washing machine drum is coaxially mounted with a rotating shaft 2. The inner part of the outer drum 1 is provided with a clothes cleaning mechanism 3 to prevent clothes from getting tangled and a conical back cover mechanism 4. When washing clothes, the clothes cleaning mechanism 3 will continuously bring the clothes to the highest point and then drop them. At the same time, the conical back cover mechanism 4 will make the clothes stick tightly to the inner wall of the drum.

[0024] To bring the clothes to the highest point inside the drum and then drop them, achieving the effect of patting the clothes, this embodiment includes a clothes washing mechanism 3. Specifically, the clothes washing mechanism 3 includes an inner drum body 301 movably installed inside the outer drum 1. A drainage channel is provided between the outer drum 1 and the inner drum body 301. Water inside the inner drum body 301 can flow into the drainage channel through a circular through-hole 307. A drain valve is provided on the outer drum 1. During the washing process, the drain valve is initially in a closed state. When the water level inside the inner drum body 301 reaches a preset value, the drain valve will automatically open to release the water. Several sets of gem-shaped protrusions are evenly spaced on the inner side wall of the inner drum body 301. The inner cylinder 301 has a first groove 303 between two adjacent sets of gem-shaped protrusions 302. A V-shaped rib assembly 304 is fixedly installed on the inner wall of the inner cylinder 301. Rectangular protrusions 305 are symmetrically arranged on both sides of the V-shaped rib assembly 304. A second groove 306 is formed between two adjacent sets of rectangular protrusions 305. The rectangular protrusions 305 and the second groove 306 are arranged alternately to form a unique clothing guiding path. Several circular through holes 307 are formed through the outer wall of the inner cylinder 301. When the V-shaped rib assembly 304 rotates with the inner cylinder 301, it will bring the clothes to the highest point inside the cylinder and then drop them, thereby achieving the effect of patting the clothes.

[0025] To ensure that the roller back cover 402 has a certain conical depth and that the clothes can be evenly attached to the inner wall of the inner drum 301 during the spin-drying process, this embodiment provides a conical back cover mechanism 4. Specifically, the conical back cover mechanism 4 includes a back cover reinforcing plate 401 coaxially arranged with the outer roller 1, and a roller back cover 402 coaxially arranged on the inner drum 301. A rotating shaft 2 passes through the back cover reinforcing plate 401 and is fixedly connected to the roller back cover 402. When the rotating shaft 2 rotates, the roller back cover 402 and the inner drum 301 will rotate synchronously. The roller back cover 402 is movably connected to the back cover reinforcing plate 401. The roller back cover 402 is provided with a first-level step 403 and a second-level step 404. The first-level step 403 and the second-level step 404 are formed by stamping the roller back cover 402 in one piece, which can effectively ensure the strength of the roller back cover 402 and prevent bending.

[0026] As can be seen from the above, when washing clothes, the user will put the clothes inside the inner drum body 301. Then, the inner drum body 301 and the rear cover of the drum will rotate under the drive of the rotating shaft 2.

[0027] Because the gem-shaped protrusions 302 and the first groove 303 are arranged in an alternating pattern, they form a unique clothing guidance path. Therefore, when the inner cylinder 301 rotates, the clothing will continuously change position under the combined action of the gem-shaped protrusions 302 and the first groove 303, which can effectively prevent the clothing from getting tangled together.

[0028] Moreover, when the inner drum body 301 rotates, multiple V-shaped rib components 304 will rotate synchronously. When the V-shaped rib components 304 rotate, the rectangular protrusions 305 and the second grooves 306 evenly distributed on the surface of the V-shaped rib components 304 can greatly increase the friction between the V-shaped rib components 304 and the clothes, thereby bringing the clothes to the highest point inside the drum and dropping them, which can effectively increase washing efficiency and cleaning power.

[0029] In addition, such as Figure 5 As shown, the drum back cover 402 has an integrally formed first-level step 403 and second-level step 404, which gives the drum back cover 402 a certain conical depth. This can effectively distribute the clothes evenly to the inner wall of the inner drum 301, ensuring that the clothes are evenly distributed, maintaining the balance between the clothes and the inner drum during spin-drying, reducing machine vibration, and extending the machine's service life.

[0030] This embodiment, by setting up a clothes washing mechanism 3, utilizes the cooperation between the gem-shaped protrusion 302 and the V-shaped rib assembly 304 to effectively prevent clothes from tangling inside the inner drum 301, and to bring the clothes to the highest point inside the drum during the washing process before dropping them, which can greatly improve washing efficiency and cleanliness. Moreover, this embodiment, by setting up a conical rear cover mechanism 4, utilizes the cooperation between the first-level step 403 and the second-level step 404 to give the drum rear cover 402 a certain conical depth, ensuring that the clothes can be evenly attached to the inner wall of the inner drum 301 during the spin-drying process, thereby ensuring that the clothes and the inner drum are more balanced during spin-drying, reducing machine vibration, and effectively extending the service life of the machine.
