Description

Technical Field

[0001] This invention belongs to the field of clothing washing and care technology, and particularly relates to a washing machine. Background Technology

[0002] With the improvement of people's living standards and the increasing pursuit of health, the demand for separate washing of underwear, socks, infant clothing, and small items of clothing is growing. To address this, related technologies have proposed a solution of configuring a smaller tub inside a larger tub; in this solution, the smaller tub is detachably attached to the impeller of the larger tub, and the larger tub's impeller drives the smaller tub to rotate. However, this existing technical solution has the following drawbacks: ① Problems with encroaching washing space and tangled clothes: The smaller tub is placed inside the larger tub, reducing its washing capacity and making clothes more prone to tangling, thus affecting washing performance. ② Problems with cumbersome operation: The smaller tub must be removed before using the larger tub, which is inconvenient and results in a poor user experience. ③ Problems with cross-contamination: The larger and smaller tubs share the same washing water, leading to cross-contamination of bacteria and dirt and poor hygiene. ④ Problems with poor washing and spin-drying performance: During washing, there is no relative movement between the impeller and the drum body of the smaller tub, resulting in insufficient washing power and poor cleaning effect. At the same time, the rotation of the smaller tub is unstable during spin-drying, resulting in low spin-drying efficiency. ⑤ Problems with inconvenient structural design: The smaller tub is connected to the balance ring via a snap-fit ​​structure, requiring the smaller tub to be disassembled before using the larger tub to place clothes, which is inconvenient.

[0023] Compared with the prior art, the main advantages of the present invention are as follows: (1) Achieve healthy zoned washing; Since the first inner drum and the second inner drum are independent of each other and not connected, the water flow and clothing contact between the two washing areas are isolated from each other in terms of physical structure; This allows small items of clothing (such as underwear and socks) to be washed completely separately from large items of clothing, fundamentally eliminating the problem of cross-infection of bacteria and dirt caused by sharing washing water, and meeting users' high-quality demand for healthy washing. (2) Significantly improves the cleaning effect of small items of clothing; In the independent washing state, by controlling the first washing unit and the second washing unit to move independently in the stationary first inner drum and the second inner drum respectively, a strong relative movement between the washing unit and its respective inner drum body is achieved; the water flow is more intense, the washing power of small items of clothing is stronger, and the cleaning effect is better. (3) Optimizes space utilization and ease of operation; the first and second washing mechanisms are integrated into the same outer drum, eliminating the need for disassembling and assembling the small drum before using the large drum, as is the case with existing technologies; users can choose to use any washing mechanism according to the type of clothing at any time, greatly simplifying the operation process and fundamentally improving the user experience; at the same time, the structure is compact, avoiding the actual encroachment of the small drum on the washing space of the large drum and the problem of clothes tangling. (4) It ensures efficient and stable synchronous dehydration and drainage; in the synchronous dehydration and drainage state, by driving the first inner drum and the second inner drum to rotate synchronously, the clothes in the first inner drum and the second inner drum can be dehydrated at high speed at the same time; this not only greatly improves the washing efficiency of the whole machine and shortens the washing cycle, but also the synchronous rotation of the two inner drums helps to maintain the dynamic balance of the whole system, reduces vibration and noise, and makes the dehydration process more stable and reliable. (5) A balance between the independence and sharing of washing resources is achieved; the first inner drum and the second inner drum are independent during washing, ensuring the hygiene and washing are targeted; while during drainage, the wastewater is discharged in a unified manner through the shared outer drum and drain outlet; this design simplifies the water system structure, improves the space and structural utilization rate, and reduces the complexity and manufacturing cost of the whole machine while ensuring functional independence.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0028] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0029] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0031] Existing washing machine designs with a detachable smaller tub inside the larger tub have significant drawbacks: the smaller tub takes up space in the larger tub and easily tangles clothes; it requires repeated disassembly and reassembly, making operation cumbersome; the two tubs share the same washing water, leading to cross-contamination; and the pulsator inside the smaller tub has no relative movement to the drum body, resulting in poor washing performance. These problems directly correspond to the core technical problem to be solved by claim 1 of this invention, namely, how to achieve true independence between the two washing spaces, avoid cross-contamination, improve washing performance, and simplify operation; This invention creatively provides a washing machine, including an outer drum, a first washing mechanism, and a second washing mechanism; a first inner drum and a second inner drum are both disposed inside the outer drum, and a first washing component and a second washing component are movably disposed inside the first inner drum and the second inner drum, respectively; the first inner drum and the second inner drum are not connected to each other but are both connected to the outer drum; when the first washing mechanism and the second washing mechanism are in an independent washing state, the first inner drum and the second inner drum are both stationary, and the first washing component and the second washing component move independently to wash the clothes in the first inner drum and the second inner drum, respectively; when the first washing mechanism and the second washing mechanism are in a synchronous spin-drain state, the first washing component and the second washing component are both stationary, the first inner drum and the second inner drum rotate synchronously, and the water in the first inner drum and the second inner drum is discharged into the outer drum and discharged through the drain outlet of the outer drum; achieving healthy partitioned washing and significantly improving the washing effect of small items of clothing.

[0032] like Figures 1a to 6 As shown, this embodiment provides a washing machine, including an outer drum 3, a first washing mechanism 1, and a second washing mechanism 2; The first washing mechanism 1 includes a first inner drum 11 and a first washing component 12. The first inner drum 11 is disposed inside the outer drum 3, and the first washing component 12 is movably disposed inside the first inner drum 11. The second washing mechanism 2 includes a second inner drum 21 and a second washing component 22. The second inner drum 21 is disposed inside the outer drum 3, and the second washing component 22 is movably disposed inside the second inner drum 21. The first inner drum 11 and the second inner drum 21 are not connected to each other and have independent water intake, washing, drainage and spin-drying processes. The first inner drum 11 and the second inner drum 21 physically form two independent washing zones. Depending on the size of the washing zone, clothes of corresponding volume can be washed separately, realizing independent washing of large and small items. For example, large items can be washed in the first inner drum 11 and small items can be washed in the second inner drum 21. This improves the washing effect of small items while avoiding cross-contamination between small and large items, meeting users' high-quality demand for healthy washing. The first inner drum 11 and the second inner drum 21 are both connected to the outer drum 3. The first inner drum 11 and the second inner drum 21 can drain water into the outer drum 3 respectively, and then drain water into the outside of the washing machine through the outer drum 3. The first washing unit 1 and the second washing unit 2 have independent washing and synchronous dewatering states; When the first washing mechanism 1 and the second washing mechanism 2 are in independent washing mode, the first inner drum 11 and the second inner drum 21 are both stationary, and the first washing component 12 and the second washing component 22 move independently of each other. The first washing component 12 can wash the clothes in the first inner drum 11, and the second washing component 22 can wash the clothes in the second inner drum 21. The first washing component 12 washes the clothes in the first inner drum 11, and the second washing component 22 washes the clothes in the second inner drum 21, so as to achieve zoned washing while ensuring washing power and cleaning effect. When the first washing mechanism 1 and the second washing mechanism 2 are in the synchronous spin-drying state, the first washing component 12 and the second washing component 22 are both stationary, and the first inner drum 11 and the second inner drum 21 rotate synchronously. The clothes in the first inner drum 11 and the second inner drum 21 are dehydrated separately, and the water in the first inner drum 11 and the second inner drum 21 is discharged into the outer drum 3 and discharged through the drain port of the outer drum 3. By driving the first inner drum 11 and the second inner drum 21 to rotate synchronously, the clothes in the first inner drum 11 and the second inner drum 21 can be dehydrated at high speed at the same time. This improves the washing efficiency of the whole machine, shortens the washing cycle, and the synchronous rotation of the first inner drum 11 and the second inner drum 21 helps to maintain the dynamic balance of the whole system, reducing vibration and noise. The first washing mechanism 1 and the second washing mechanism 2 are integrated into the same outer drum 3. Users can choose to use either washing mechanism according to the type of clothing, which greatly simplifies the operation process. The two inner drums are independent during washing, and the washing water is discharged in a unified manner through the shared outer drum 3 and drain outlet during drainage. While ensuring functional independence, the water system structure is simplified.

[0033] Furthermore, the first inner cylinder 11 has a first inner cylinder opening 111; the second inner cylinder 21 is movably disposed at the first inner cylinder opening 111; the second inner cylinder 21 has a first working position and a second working position; When the second inner tube 21 is in the first working position, the second inner tube 21 is away from the first inner tube opening 111, and clothes can be put into the first inner tube 11 or taken out of the first inner tube 11 through the first inner tube opening 111. When the second inner cylinder 21 is in the second working position, the second inner cylinder 21 and the first inner cylinder 11 can be connected together in a synchronous rotation, thereby realizing dehydration and drainage; During washing, the first inner drum 11 and the second inner drum 21 are independent of each other and do not interfere with each other; when putting clothes into or taking clothes out of the first inner drum 11, it is only necessary to put the second inner drum 21 in the first working position.

[0034] The following describes the structure required for the second inner drum 21 to switch between the first working position and the second working position. The first washing mechanism 1 also includes a balance ring 13, which is disposed at the opening 111 of the first inner drum. The second washing mechanism 2 also includes a water collecting component 23, which is disposed on the balance ring 13 and has a first mounting port 231. Specifically, the water collecting component 23 can be mounted on the balance ring 13 by welding. The second inner cylinder 21 is located at the first mounting port 231, and the axial direction of the second inner cylinder 21 is vertical; the second inner cylinder 21 and the water collecting component 23 are movably connected, and the second inner cylinder 21 can be flipped up and down relative to the water collecting component 23. By flipping the second inner cylinder 21 up and down relative to the water collecting component 23, the second inner cylinder 21 can be switched between the first working position and the second working position; flipping the second inner cylinder 21 is simple and convenient to operate. When the second inner cylinder 21 is in the second working position, the water collecting component 23 and the second inner cylinder 21 cover the top of the first inner cylinder opening 111.

[0035] Furthermore, the water collecting component 23 has a ring structure, and the water collecting component 23 includes a first connecting part 232 and a second connecting part 233, which are arranged opposite to each other in the diameter direction of the water collecting component 23. The second inner cylinder 21 has a second inner cylinder opening 211, and the second inner cylinder opening 211 is provided with an annular seat 24. The annular seat 24 includes a third connecting part 241 and a fourth connecting part 242, which are arranged opposite to each other in the diametrical direction of the annular seat 24. The annular seat 24 and the water collecting component 23 are coaxially arranged; the third connecting part 241 and the first connecting part 232 are correspondingly arranged and rotatably connected. Specifically, the third connecting part 241 and the first connecting part 232 are rotatably connected through the first rotating shaft 271; the fourth connecting part 242 and the second connecting part 233 are correspondingly arranged and the second connecting part 233 and the fourth connecting part 242 have a loose state and a locked state. When the second connecting part 233 and the fourth connecting part 242 are in the loosened state, the second inner cylinder 21 can be flipped up and down relative to the water collecting part 23. When the second connecting part 233 and the fourth connecting part 242 are in the locked state, the second inner cylinder 21 can rotate synchronously with the first inner cylinder 11.

[0036] The structure required for switching between the second connecting part 233 and the fourth connecting part 242 in the loosened state and the locked state will be described below. The second connecting part 233 and the fourth connecting part 242 are connected by magnetic force. Specifically, the second connecting part 233 is provided with a first magnetic element 621, and the fourth connecting part 242 is provided with a second magnetic element 622. When the external force does not act on the annular seat 24 or the external force is less than the magnetic force between the first magnetic element 621 and the second magnetic element 622, the second connecting part 233 and the fourth connecting part 242 are in a locked state, and the annular seat 24 and the water collecting part 23 are connected. When the external force acts on the annular seat 24 and the external force is greater than the magnetic force between the first magnetic element 621 and the second magnetic element 622, the second connecting part 233 and the fourth connecting part 242 are in a loosened state, and the annular seat 24 and the water collecting part 23 are separated.

[0037] The drainage path of the second inner cylinder 21 is described below. The second inner cylinder 21 is provided with a second drainage hole 212 near the second inner cylinder opening 211. A drainage channel 234 is formed inside the water collecting component 23. The second inner cylinder 21, the second drainage hole 212, the drainage channel 234 and the outer cylinder 3 are connected in sequence.

[0038] Furthermore, in the vertical direction, the water collecting element 23 is shaped like a frustum cone; along the radial direction of the water collecting element 23 from the inside to the outside, the extension direction of the drainage channel 234 is inclined downward relative to the horizontal direction.

[0039] Specifically, multiple second drain holes 212 are provided, and the multiple second drain holes 212 are arranged at intervals along the circumference of the second inner cylinder 21; Multiple drainage channels 234 are provided, and the multiple drainage channels 234 are arranged at intervals along the circumference of the water collection component 23; The second inner cylinder 21 and the water collection component 23 are coaxially arranged, and multiple second drain holes 212 and multiple drain channels 234 are arranged in a one-to-one correspondence and are connected.

[0040] The following describes the structure required for drainage of the second inner drum 21. The opening 211 of the second inner drum faces upward; the position of the annular seat 24 is higher than the position of the second drain hole 212; a water-blocking ring 25 is provided on the radial inner side of the annular seat 24. When the second inner drum 21 is draining or dehydrating, the washing water flows upward along the drum wall of the second inner drum 21 under the action of centrifugal force. Under the action of the water-blocking ring 25, the washing water is blocked to the second drain hole 212 and discharged through the second drain hole 212. Specifically, the water-blocking ring 25 can be mounted on the annular seat 24 by means of screw connection or riveting.

[0041] The following describes the specific structure of the second inner drum 21 switching between the first working position and the second working position.
