Abstract
Description
Technical Field
[0001] This disclosure relates to the field of washing equipment technology, and in particular to a multi-zone washing machine and its inner drum. Background Technology
[0002] Multi-zone washing machines have become widely available on the market, and multi-zone washing machines have become one of the development trends in the washing machine industry. However, most current multi-zone washing machines still use an outer tub with an inner tub, which is basically the same as the washing method of a large tub. During washing and spin-drying, the inner tub rotates relative to the outer tub to achieve washing and spin-drying. In this way, multi-zone washing machines are simply multiple sets of such components.
[0003] However, multi-zone systems using an outer drum paired with an inner drum require arranging the outer and inner drums side by side, which wastes a lot of space and materials, increases the complexity of components, and increases vibration when multiple drums are dehydrating at the same time. It is also prone to slapping problems due to the different rotation speeds of each drum. Utility Model Content

[0051] The present disclosure will be explained more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.
[0052] Example 1
[0053] In one specific embodiment of this disclosure, a multi-zone washing machine inner drum is provided, such as... Figure 1-2 As shown, the inner drum of the multi-zone washing machine includes an inner drum body 1 and a partition cover 2;
[0054] The inner drum body 1 includes at least two independent washing partition structures 3;
[0055] Each partition structure 3 corresponds to a partition cover 2. When the corresponding partition cover 2 is closed, the partition structure 3 forms a closed space.
[0056] Specifically, the multi-zone washing machine drum of this embodiment includes an inner drum body 1 and a partition cover 2 disposed on the inner drum body 1. The inner drum body 1 includes at least two independent washing partition structures 3. Each partition structure 3 rotates with the inner drum body 1 to perform washing or spin-drying functions, and each partition structure 3 is not interconnected during washing and spin-drying. Each partition structure 3 also corresponds to a partition cover 2 on the inner drum body 1, so that during washing or spin-drying, closing the partition cover 2 makes each partition structure 3 form a closed space, and opening the partition cover 2 when the washing stops allows clothes to be taken out and put in from the corresponding partition structure 3, thereby realizing the function of a single inner drum including multiple partitions. The partition cover 2 can be rotatably disposed on the inner drum body 1 or flipped onto the inner drum body 1, and the partition structures 3 can be the same or different.
[0057] This specific implementation achieves multi-zone functionality within a single inner drum through a multi-zone, single-drum design. During washing and dehydration, only one drum operates, greatly saving space and materials while reducing component complexity. During dehydration, only a single dynamic load exists, avoiding problems such as excessive tapping and vibration.
[0058] In one specific implementation, such as Figure 1As shown, the inner cylinder body 1 includes a front cylinder cover 11, a cylinder body 12, and a cylinder bottom 13;
[0059] The front cover 11 and the bottom 13 are respectively provided at both ends of the cylinder body 12;
[0060] The cylinder 12 is formed by splicing together at least two partition structures 3; or, the cylinder 12 is provided with a number of partitions inside, which are used to divide the inner cylinder body 1 into at least two partition structures 3.
[0061] The area corresponding to the front cylinder cover 11 of the partition structure 3 is provided with a partition cover plate 2.
[0062] Specifically, the front cap 11, the tube body 12, and the bottom 13 together constitute the inner tube body 1. The tube body 12 can be formed by splicing together multiple partition structures 3, or several partitions can be set inside the tube body 12 to divide the inner tube body 1 into multiple partition structures 3. The accommodating space of each partition structure 3 can be the same or different. A partition cover 2 is set on the area of the front cap 11 corresponding to each partition structure 3, so that the partition structure 3 can be connected to the outside through the partition cover 2, realizing the loading and unloading of clothes.
[0063] When the cylinder 12 is assembled using multiple partitioned structures 3, such as Figure 3 As shown, each partition structure 3 has space to accommodate clothes, and each partition structure 3 can be completely connected to each other to form a complete drum 12 with multiple independent washing spaces after being assembled.
[0064] When partitions are used for separation, several partitions can be directly set inside the cylinder 12 to divide the inner cylinder body 1 into multiple partition structures 3 with independent spaces. For example, one partition can be set inside the cylinder 12 to divide the inner cylinder body 1 into two partition structures 3, or two partitions can be set inside the cylinder 12 to divide the inner cylinder body 1 into three or four partition structures 3, etc.
[0065] In one specific implementation, such as Figure 4 As shown, the interior of the cylinder 12 includes a first partition 31, a second partition 32, and a third partition 33;
[0066] The first partition 31 is located at a preset position inside the cylinder 12 to divide the inner cylinder body 1 into a first initial partition and a second initial partition.
[0067] The second partition 32 is positioned at a first preset angle in the first initial partition, and the third partition 33 is positioned at a second preset angle in the second initial partition, so that the inner drum body 1 forms four independent washing partition structures 3.
[0068] Specifically, the first partition 31 can be set in the middle of the inner drum 12. The inner drum body 1 is divided into two equal parts, the first initial partition and the second initial partition, by the first partition 31. The first initial partition is then divided into two independent washing partition structures 3 by the second partition 32. The second initial partition is then divided into two independent washing partition structures 3 by the third partition 33. Thus, four independent washing partition structures 3 can be formed in the inner drum body 1.
[0069] To facilitate the effective drainage of washing water from the left and right partition structures 3, the second partition plate 32 and the third partition plate 33 can be tilted to both sides to form the lowest drainage position. Of course, the second partition plate 32 and the third partition plate 33 can be tilted to one side at the same time, or they can be tilted relative to each other. This specific embodiment does not limit this.
[0070] In one specific embodiment, the partition includes a dividing surface of a predetermined shape.
[0071] Specifically, to improve the washing efficiency of each partition structure 3 under washing conditions, the partition plates can be set as partition surfaces with preset shapes, thereby dividing the interior of the inner drum body 1 into partition structures 3 with irregularly shaped spaces. For example, a spiral partition plate can be used to divide the interior of the inner drum body 1 into multiple partition structures 3 with irregularly shaped spaces, such as... Figure 3 , 5 As shown, during the rotation of the inner drum body 1, the clothes move from high to low inside, increasing the drop of the clothes and generating a greater physical tumbling force. This effectively improves the washing ratio of each zone structure 3 and avoids the problem of a small drop of the clothes and a poor washing ratio caused by the small drum diameter of the zone structure 3.
[0072] In one specific implementation, such as Figure 4 , 6 As shown in Figure 7, the inner cylinder body 1 and the rear cylinder cover 4 are coaxially arranged.
[0073] The rear cylinder cover 4 has several pre-set drainage pipes 41 on its exterior;
[0074] The bottom 13 area of the cylinder corresponding to the partition structure 3 is provided with a drainage outlet 14;
[0075] The inner cylinder body 1 is used to rotate to a fixed position during dehydration, so that the drain outlet 14 of each partition structure 3 is connected to the drain pipe 41 of the rear cylinder cover 4 to achieve drainage.
[0076] Specifically, the inner drum body 1 can be a non-perforated design. Except for liquid flow holes (e.g., water inlet and drain) and gas flow holes, the rest of the inner drum body 1 is non-perforated. The drain outlet 14 can be located at the lowest position of each partition structure 3 to facilitate effective drainage of washing water. At the same time, a drain pipe 41 is externally fixed on the rear drum cover 4, which is coaxially arranged with the inner drum body 1. When drainage is required before the start of spin-drying, the inner drum body 1 rotates and positions itself to connect with the drain pipe 41 corresponding to the drain outlet 14 of each partition structure 3 to achieve drainage.
[0077] Of course, other accessories for the multi-zone washing machine inner drum, such as a motor, can also be installed on the rear drum cover 4, but this specific embodiment does not limit this.
[0078] In one specific implementation, such as Figure 2 , 6 As shown in Figure 7, the inner drum of the multi-zone washing machine also includes a support bracket 42; the support bracket 42 is fixed on the rear drum cover 4, which is coaxially arranged with the inner drum body 1, and the support bracket 42 is used to support the inner drum body 1; a vibration damper 43 may also be provided on the support bracket 42 to avoid causing resonance of the cabinet.
[0079] This specific embodiment achieves multi-zone functionality within a single inner drum through a multi-zone, single-drum design. During washing and spin-drying, only one drum operates, significantly saving space and materials while reducing component complexity. During spin-drying, only a single dynamic load exists, avoiding problems such as excessive tumbling and vibration. Furthermore, the increased drop height of clothes during washing effectively improves the washing efficiency of each zone.
[0080] Example 2
[0081] In one specific embodiment of this disclosure, a multi-zone washing machine is provided, which includes the multi-zone washing machine inner drum of any of the above embodiments.
[0082] In one specific implementation, such as Figure 8 As shown, the multi-zone washing machine includes a cabinet 5;
[0083] The cabinet 5 is provided with a clothes loading and unloading port 51, and the area of the clothes loading and unloading port 51 covers the area where each section cover 2 of the inner drum of the multi-section washing machine is located.
[0084] Specifically, the box body 5 is provided with a clothing loading and unloading port 51. The area of the clothing loading and unloading port 51 can be set to cover the area where each partition cover 2 is located, so that clothing can be loaded and unloaded in each partition structure 3 at the same time through the clothing loading and unloading port 51.
[0085] In another specific implementation, such as Figure 9As shown, the multi-zone washing machine includes a cabinet 5;
[0086] The cabinet 5 is provided with a clothes loading and unloading port 51. The area of the clothes loading and unloading port 51 covers the area where a partition cover 2 is located. The multi-partition washing machine is used to rotate the inner drum of the multi-partition washing machine when it is stopped, so that each partition cover 2 is aligned with the clothes loading and unloading port 51 in turn.
[0087] Specifically, the area of the clothes loading and unloading port 51 can be set to cover the area where a partition cover 2 is located. When it is necessary to load or unload clothes from another partition structure 3, the inner drum of the multi-partition washing machine can be rotated so that the partition cover 2 of the target partition structure corresponds to the clothes loading and unloading port 51. At this time, the clothes inside the target partition structure fall from a high place to a low place (i.e., the partition cover opening) due to gravity, so as to facilitate the loading and unloading of clothes in the target partition structure.
[0088] This specific embodiment achieves multi-zone functionality within a single inner drum through a multi-zone, single-drum design. During washing and spin-drying, only one drum operates, significantly saving space and materials while reducing component complexity. During spin-drying, only a single dynamic load exists, avoiding problems such as excessive tumbling and vibration. Furthermore, the increased drop height of clothes during washing effectively improves the washing efficiency of each zone.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
