Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a multi-drum washing machine. Background Technology

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0003] As an important household appliance, washing machines have greatly reduced people's housework burden. However, existing single-drum washing machines typically have a small washing capacity, requiring multiple washes to complete the washing of large loads of clothes. Moreover, they cannot perform separate washing for different types of clothing. If the drum of a single-drum washing machine is designed to be too large, it will not only be inconvenient to install and transport but also result in poor washing performance. If the drum is designed to be too small, it can hold too few clothes, leading to low washing efficiency. Utility Model Content

[0004] This application discloses a multi-drum washing machine that ensures that the upper small drum can wash small items of clothing normally, while the lower large drum has enough space to wash large items of clothing.

[0005] To achieve the above objectives, embodiments of this application disclose a multi-drum washing machine, comprising:

[0006] A housing having an accommodating space within it, the housing comprising:

[0007] The upper front panel is provided with a first opening and a second opening, which are arranged side by side in the horizontal direction.

[0008] The lower front panel is located below the upper front panel, and the lower front panel has a third opening;

[0009] A first roller is disposed inside the housing, and the opening of the first roller corresponds to the first opening;

[0010] The second roller is disposed inside the housing, and the opening of the second roller corresponds to the second opening;

[0011] A third roller is disposed inside the housing, and the opening of the third roller corresponds to the third opening;

[0012] A drive assembly is disposed within the housing, and the drive assembly is respectively connected to the first roller, the second roller, and the third roller to drive the first roller, the second roller, and the third roller to rotate;

[0013] The first door body is disposed at the first opening to open or close the first opening, and the intersection of the axis of the first roller and the outer surface of the first door body is the first intersection point;

[0014] The second door is disposed at the second opening to open or close the second opening. The intersection of the axis of the second roller and the outer surface of the second door is the second intersection point, and the second intersection point and the first intersection point are located on the same horizontal plane.

[0015] The third door is located at the third opening to open or close the third opening. The intersection of the axis of the third roller and the outer surface of the third door is the third intersection point.

[0016] In the vertical direction, the ratio of the height of the upper front plate to the height of the lower front plate is 0.411 to 0.588.

[0017] Therefore, when the ratio of the height of the upper front panel to the height of the lower front panel is less than 0.411, the height of the upper front panel is too small. Given a fixed depth of the housing and a fixed width of the front panel in the horizontal direction, a smaller upper front panel height results in less space for the first and second openings, and a smaller area for the openings of the first and second rollers. Consequently, when the depth of the first and second rollers is constant, their internal space will be smaller. Since the first and second rollers are typically used for washing small items of clothing, this leads to a small number of small items being washed at a time, resulting in low washing efficiency.

[0018] In addition, the lower front panel is too high. If the two small drums at the top and the large drum at the bottom are detachable, it will be difficult to take the two upper drums of the washing machine out of the machine, and it will also be inconvenient to take clothes out of the small drums at the top.

[0019] When the ratio of the height of the upper front panel to the height of the lower front panel is greater than 0.588, the height of the lower front panel is too small. Given a fixed depth of the housing and a horizontal width of the front panel, a smaller lower front panel height results in less space for the third opening and a smaller opening area for the third roller. Therefore, when the depth of the third roller is constant, its internal space will be smaller. Since the third roller is typically used for washing large items such as blankets, quilts, and coats, this can prevent some oversized items from fitting into the large roller, limiting its applicability. Furthermore, users may need to bend over excessively when loading and unloading clothes, leading to a poor user experience.

[0020] Therefore, being within this range ensures both the washing efficiency of the small tub and the applicability of the large tub, making it more convenient for users to take out and put out clothes from either the small or large tub, thus enhancing the user experience.

[0021] As an optional implementation, the ratio of the height of the upper front plate to the height of the lower front plate is 0.432 to 0.648 in the vertical direction.

[0022] In this way, the height of the upper front panel is close to half the height of the lower front panel. The space in the two small drums at the top is not too small, which would result in too few small items of clothing being washed at once. At the same time, the space in the large drum at the bottom is spacious enough to meet the larger space required for washing large items of clothing. This further ensures the washing efficiency of the small drums at the top and the applicability of the large drum, making it more convenient for users to take out and put in clothes from both the small and large drums, thus enhancing the user experience.

[0023] As an optional implementation, the height of the upper front plate is 350mm to 500mm in the vertical direction, and the height of the lower front plate is 616mm to 924mm.

[0024] Therefore, when the height of the upper front panel is too small and the height of the lower front panel is too large, given a fixed depth of the casing and a horizontal width of the front panel, the smaller height of the upper front panel results in a smaller internal space for the first and second rollers, leading to a smaller capacity for washing small items of clothing at once and low washing efficiency. Conversely, when the height of the lower front panel is too small, the smaller height of the lower front panel, given a fixed depth of the casing and a horizontal width of the front panel, results in a smaller internal space for the third roller, preventing the placement of larger items in the larger drum and limiting its applicability. When the heights of the upper and lower front panels fall within this range, both the washing efficiency of the smaller drum and the applicability of the larger drum are ensured, making it easier for users to retrieve clothing from both the smaller and larger drums, thus enhancing the user experience.

[0025] As an optional implementation, both the first door and the second door are circular and have the same diameter. In the vertical direction, the ratio of the diameter of the first door to the height of the upper front panel is 0.5 to 0.7, and in the horizontal direction, the ratio of the diameter of the first door to the width of the upper front panel is 0.34 to 0.47.

[0026] Thus, given a fixed depth of the shell and a fixed width of the front panel in the horizontal direction, if the ratio of the diameter of the first door to the height of the upper front panel is too small, or if the ratio of the diameter of the first door to the width of the upper front panel is too small, the first door will be too small, and the corresponding opening will be too small, making it inconvenient to place clothes.

[0027] Additionally, if the ratio of the diameter of the first door to the height of the upper front panel is too small, it may indicate that the upper front panel is too tall. This would result in the upper front panel occupying too much space, leading to wasted space. Furthermore, if the upper front panel is too large, it would make disassembling and assembling the twin-tub washing machine inconvenient, especially if the two smaller tubs at the top are detachable and usable independently. Similarly, if the ratio of the diameter of the first door to the width of the upper front panel is too small, it may indicate that the upper front panel is too wide. This would also result in the upper front panel occupying too much width space, leading to wasted space. Moreover, the excessive size of the upper front panel not only makes disassembling and assembling the twin-tub washing machine inconvenient but also affects its usability. The excessive width of this multi-tub washing machine means it can only be placed in a sufficiently wide space, impacting the user experience.

[0028] If the ratio of the diameter of the first door to the height of the upper front panel is too large, or the ratio of the diameter of the first door to the width of the upper front panel is too large, it means that the first door is too large, resulting in the first door being too heavy. This not only makes it difficult to transport, but also makes it inconvenient for users to open the door and perform other operations.

[0029] In addition, if the ratio of the diameter of the first door to the height of the upper front panel is too large, or the ratio of the diameter of the first door to the width of the upper front panel is too large, the door will occupy too much space, which will also result in too little space for other components on the upper front panel (such as control knobs), making the space layout of the washing machine unreasonable and affecting the user experience.

[0030] Therefore, within this range, the size of the first door is appropriate, ensuring the convenience of placing clothes and opening and closing the door. The layout of each component on the front panel is more reasonable, reducing the waste of space on the front panel and enhancing the user experience.

[0031] As an optional implementation, the ratio of the diameter of the first door body to the height of the upper front panel in the vertical direction is 0.432 to 0.648, and the ratio of the diameter of the first door body to the width of the upper front panel in the horizontal direction is 0.336 to 0.504.

[0032] In this way, the ratio of the area of ​​the first door to the area of ​​the front panel is more reasonable, further ensuring the convenience of placing clothes and opening and closing the door. The layout of each component on the upper front panel is also more reasonable, further reducing the waste of space on the upper front panel and effectively enhancing the user experience.

[0033] As an optional implementation, the diameter of the first door body is 199mm to 299mm in the vertical direction.

[0034] With a fixed width for the upper front panel and a fixed height for the upper front panel within this range, the dimensions of the first door are more reasonable within this range, ensuring the convenience of placing clothes and opening and closing the door. The layout of each component on the upper front panel is also more reasonable, further reducing the waste of space on the upper front panel and enhancing the user experience.

[0035] As an optional implementation, the third door is a circular door. In the vertical direction, the ratio of the diameter of the third door to the height of the lower front panel is 0.496 to 0.744, and in the horizontal direction, the ratio of the diameter of the third door to the width of the lower front panel is 0.712 to 0.96.

[0036] Thus, when the width and height of the lower front panel are fixed, if the ratio of the diameter of the third door to the height of the lower front panel is too small or the ratio of the diameter of the third door to the width of the lower front panel is too small, it means that the area of ​​the third door is too small, and the corresponding opening is too small, making it inconvenient to place large items.

[0037] Furthermore, when the diameter of the third door is fixed, if the ratio of the third door's diameter to the height of the lower front panel is too small, it means the lower front panel is too tall. If the two upper smaller drums and the lower larger drum are detachable, it will be difficult to access the upper two drums, and it will also be inconvenient to load and unload clothes into the upper smaller drums. If the ratio of the third door's diameter to the width of the lower front panel is too small, it means the lower front panel is too wide, forcing it to fit only in spaces with sufficient width, thus affecting the user experience.

[0038] If the ratio of the diameter of the third door to the height of the lower front panel is too large, or the ratio of the diameter of the third door to the width of the lower front panel is too large, it means that the third door is too large, resulting in excessive weight, making it difficult to transport, and making it inconvenient for users to open the door and perform other operations.

[0039] In addition, when the diameter of the third door is fixed, if the ratio of the diameter of the third door to the height of the lower front panel or the ratio of the diameter of the third door to the width of the lower front panel is too large, it means that the height of the lower front panel is too small, the door occupies too much space, and it will also result in too little space for other components on the lower front panel (such as control knobs), making the space layout of the washing machine unreasonable and affecting the user experience.

[0040] Therefore, within this range, the size of the third door is appropriate, ensuring both the convenience of placing large items and opening and closing the door. The layout of each component on the lower front panel is also more reasonable, reducing the waste of space on the upper front panel and enhancing the user experience.

[0041] As an optional implementation, the diameter of the third door body is 415mm to 548mm in the vertical direction.

[0042] Therefore, when the width of the lower front panel is fixed, and the height of the lower front panel is within a certain range, if the diameter of the third door is too small, the ratio of the diameter of the third door to the height of the lower front panel or the ratio of the diameter of the third door to the width of the lower front panel is too small, the area of ​​the third door will be too small, and the corresponding opening will be too small, making it inconvenient to place large items. If the diameter of the third door is too large, the ratio of the diameter of the third door to the height of the lower front panel or the ratio of the diameter of the third door to the width of the lower front panel will be too large, resulting in an excessively large third door, making it difficult to transport, and inconvenient for users to open the door. Therefore, within this range, the size of the third door is appropriate, ensuring the convenience of placing large items and opening and closing the door. The layout of various components on the upper front panel is more reasonable, further reducing the waste of space on the upper front panel and enhancing the user experience.

[0043] As an optional implementation, the first door, the second door, and the third door are all circular doors. The first door and the second door have the same diameter, and the ratio of the diameter of the first door to the diameter of the third door is 0.376 to 0.564. The ratio of the diameter of the second door to the diameter of the third door is also 0.376 to 0.564.

[0044] Thus, when the width, height, and depth of the front panel are constant, if the ratio of the diameter of the first door to the diameter of the third door is too small, the size difference between the first and third doors will be too large, resulting in a visually uncoordinated appearance. If the ratio is too large, the diameters of the first and third doors will be similar, making it difficult for users to distinguish between the large and small tubs, and the functional division between washing small and large items in the large and small tubs is not clear. Therefore, within this range, not only is visual harmony ensured, but the distinction between the large and small tubs is also clearly defined, enhancing the user experience.

[0045] As an optional implementation, the diameter of the first door is 200mm to 281mm, the diameter of the second door is 200mm to 281mm, and the diameter of the third door is 415mm to 548mm.

[0046] Thus, with a fixed width, height, and depth of the front panel, if the diameter of the first door is too small or the diameter of the third door is too large, the significant size difference between the first and third doors will result in a visually uncoordinated appearance. Conversely, if the diameter of the first door is too large or the diameter of the third door is too small, their diameters will be similar, making it difficult for users to distinguish between the large and small drums, and the functional division between washing small and large items in the large and small drums will be unclear. Therefore, within this range, both visual harmony and clear differentiation between the large and small drums are ensured, enhancing the user experience.

[0047] As an optional implementation, the multi-drum washing machine further includes:

[0048] A touch screen is disposed on the upper front panel and located above the first door and the second door, and the touch screen is electrically connected to the driving component;

[0049] In the vertical direction, the ratio of the height of the touch screen to the height of the upper front panel is 0.056 to 0.084;

[0050] Along the horizontal direction, the ratio of the width of the touch screen to the width of the upper front panel is 0.432 to 0.648.

[0051] In this way, the touchscreen can provide an intuitive user interface, allowing users to personalize settings according to their needs. When the height and width of the front panel are fixed, if the ratio of the touchscreen's height to the front panel's height is too small, or the ratio of the touchscreen's width to the front panel's width is too small, the display area will be too small, resulting in unclear display. When the ratio of the touchscreen's height to the front panel's height is greater than 1, or the ratio of the touchscreen's width to the front panel's width is greater than 1, the touchscreen will extend beyond the edge of the front panel. Therefore, within this range, display requirements can be met, achieving efficient utilization of the front panel space.

[0052] As an optional implementation, the height of the touch screen is 12mm to 88mm in the vertical direction, and the height of the upper front panel is 350mm to 500mm.

[0053] The width of the touch screen is 179mm to 595mm in the horizontal direction.

[0054] Therefore, when the height of the front panel is within a certain range, if the touchscreen is too small in height or too wide, the display area will be too small and the display will be unclear. If the touchscreen is too large in height, it will affect the installation space of other components (such as the third roller). If the touchscreen is too wide, it will extend beyond the edge of the front panel. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5-meter range, which can meet the display requirements without affecting the installation space of other components, thus achieving efficient utilization of the front panel space.

[0055] As an optional implementation, the multi-drum washing machine further includes:

[0056] A control knob is disposed on the lower front panel and located above the third door body. The control knob is electrically connected to the drive assembly to control the rotation of the third roller.

[0057] In the vertical direction, the ratio of the height of the control knob to the height of the lower front plate is 0.072 to 0.108; in the horizontal direction...

[0058] The ratio of the width of the control knob to the width of the lower front plate is 0.104 to 0.156.

[0059] In this way, users can adjust the washing machine settings by rotating the knob. They can easily adjust parameters such as washing mode, temperature, and spin speed, allowing for quick understanding and operation without referring to the instruction manual. When the height and width of the lower front panel are fixed, if the ratio of the control knob's height to the lower front panel height is less than 0.072 or the ratio of the control knob's width to the lower front panel width is less than 0.104, the control knob is too small, making it difficult to rotate and adjust parameters such as washing mode, temperature, and spin speed. If the ratio of the control knob's height to the lower front panel height is greater than 0.108 or the ratio of the control knob's width to the lower front panel width is greater than 0.156, the control knob is too large, inconvenient for user operation, and results in a poor user experience. Within this range, users can clearly understand the purpose of the knob, and the size is appropriate, making parameter adjustment easier.

[0060] As an optional implementation, the height of the control knob is 12mm to 100mm in the vertical direction, and the height of the lower front plate is 616mm to 924mm.

[0061] The width of the control knob is 12mm to 101mm in the horizontal direction.

[0062] Thus, with a fixed width for the lower front panel and a fixed height within this range, if the height or width of the control knob is less than 12mm, the knob becomes too small, making it difficult to rotate and adjust parameters such as washing mode, temperature, and spin speed. If the height or width of the control knob is greater than 100mm, it becomes too large, making it difficult for the user to rotate it by hand. Within this range, the user can clearly understand the function of the knob, and the size is appropriate, making it more convenient to adjust parameters by rotating the knob.

[0063] As an optional implementation, the multi-drum washing machine further includes:

[0064] A detergent storage box is disposed within the housing and has a accommodating space for holding detergent. The detergent storage box is movably connected to the lower front plate so that it can be pulled out of the housing or stored inside the housing.

[0065] In the vertical direction, the ratio of the width of the detergent storage box to the height of the lower front panel is 0.112 to 0.168;

[0066] Along the horizontal direction, the ratio of the width of the detergent storage box to the width of the lower front panel is 0.328 to 0.492.

[0067] In this way, users don't need to bend over to add detergent like with traditional washing machines; they can simply pull out the detergent dispenser to easily add detergent, ensuring a better user experience. Because the soap dish has a limited depth, when the horizontal width of the detergent dispenser is fixed, the vertical volume is too small if the ratio of the height of the detergent dispenser to the height of the lower front panel is less than 0.112 or the ratio of the width of the detergent dispenser to the width of the lower front panel is less than 0.328. This will not be enough to hold sufficient detergent for the machine's rated washing capacity. Conversely, if the ratio of the height of the detergent dispenser to the height of the front panel is greater than 0.168 or the ratio of the width of the detergent dispenser to the width of the lower front panel is greater than 0.492, the volume will be too large, wasting internal space. Therefore, within this range, the internal space of the washing machine should be used efficiently while still accommodating sufficient detergent, avoiding space waste caused by an overly wide soap dish, and allowing enough space inside the washing machine for other components (such as the drum and drive assembly).

[0068] As an optional implementation, the height of the detergent storage box is 75mm to 332mm in the vertical direction, and the height of the lower front plate is 616mm to 924mm.

[0069] The width of the detergent storage box in the horizontal direction is 119mm to 298mm.

[0070] Thus, with a fixed width for the lower front panel and a fixed height within this range, if the height of the detergent dispenser is less than 75mm or the width is less than 119mm vertically, the volume of the detergent dispenser is too small to hold enough detergent for the rated washing capacity of the machine. Conversely, if the height of the detergent dispenser is greater than 332mm or the width is greater than 298mm horizontally, the volume is too large, wasting internal space. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be utilized efficiently to avoid wasting space due to an excessively wide soap dish, allowing sufficient space for other components (such as the drum and drive assembly).

[0071] As an optional implementation, the distance between the first intersection point and the third intersection point is equal to the distance between the second intersection point and the third intersection point.

[0072] In this way, the distances between the first and third intersection points, the distances between the second and third intersection points, and the distances between the first and second intersection points can form an isosceles triangle or an equilateral triangle. This shape has higher stability. When the drum rotates and there is an eccentric load, the eccentricity can be more easily offset with the cooperation of each drum, ensuring the balanced vibration reduction performance of the entire three-drum system, and thus ensuring the stability of the entire washing machine.

[0073] Compared with the prior art, the beneficial effects of this application are:

[0074] In the multi-drum washing machine provided in this application embodiment, when the ratio of the height of the upper front panel to the height of the lower front panel is less than 0.411, the height of the upper front panel is too small. Given a fixed depth of the casing and a fixed width of the front panel in the horizontal direction, a smaller upper front panel height results in less space for the first and second openings, and a smaller area for the openings of the first and second drums. Consequently, when the depth of the first and second drums is fixed, their internal accommodating space becomes smaller. Since the first and second drums are typically used for washing small items of clothing, this leads to a smaller number of small items being washed at once, resulting in low washing efficiency. When the ratio of the height of the upper front panel to the height of the lower front panel is greater than 0.588, the height of the lower front panel is too small. Given a fixed depth of the casing and a fixed width of the front panel in the horizontal direction, a smaller lower front panel height results in less space for the third opening, and a smaller area for the opening of the third drum. Consequently, when the depth of the third drum is fixed, its internal accommodating space becomes smaller. Since the third drum is typically used for washing large items such as blankets, quilts, and coats, some oversized items cannot fit into the large drum, limiting its applicability. Therefore, placing it within this range ensures both the washing efficiency of the upper smaller drum and the applicability of the large drum, making it more convenient for users to load and unload clothes from both the smaller and larger drums, thus enhancing the user experience.

[0092] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0093] As an important household appliance, washing machines have greatly reduced people's housework burden. However, existing single-drum washing machines typically have a small washing capacity, requiring multiple washes to complete the washing of large loads of clothes. Moreover, they cannot perform separate washing for different types of clothing. If the drum of a single-drum washing machine is designed to be too large, it will not only be inconvenient to install and transport but also result in poor washing performance. If the drum is designed to be too small, it can hold too few clothes, leading to low washing efficiency.

[0094] Therefore, multi-drum washing machines have unique advantages. For example, some families need to wash different types of clothing separately, such as baby clothes needing to be washed separately from adult clothes, and underwear needing to be washed separately from outerwear. Multi-drum washing machines can meet these needs simultaneously, as different drums can be set with different washing modes.

[0095] Multi-drum washing machines present a challenge due to the difficulty in arranging multiple drums in a reasonable manner.

[0096] Based on this, this application discloses a multi-drum washing machine, wherein the ratio of the height of the upper front panel to the height of the lower front panel is 0.411 to 0.588, ensuring that the upper small drum can wash small items of clothing normally, while the lower large drum has enough space to wash large items of clothing.

[0097] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0098] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the multi-drum washing machine disclosed in an embodiment of this application. Figure 2 This is a schematic diagram showing the dimensional proportions of the upper front panel 11 and the lower front panel 12 as disclosed in an embodiment of this application. This application discloses a multi-drum washing machine.

[0099] This multi-drum washing machine includes a housing 1, which serves as the external structure of the machine. The housing 1 is typically made of metal or plastic and protects the internal components, providing robust support. The housing 1 is designed with durability, heat dissipation, noise control, safety, and maintainability in mind. The interior of the housing 1 is designed around the drum to house and protect it, along with other internal structures.

[0100] In some embodiments, the housing 1 includes an upper front plate 11, on which a first opening 11a and a second opening 11b are provided, the first opening 11a and the second opening 11b being arranged side by side in the horizontal direction.

[0101] In some embodiments, the housing 1 further includes a lower front plate 12, which is connected to the upper front plate and located below the upper front plate 11, and the lower front plate 12 is provided with a third opening 12a.

[0102] In some embodiments, a multi-drum washing machine includes a first drum disposed inside the housing 1, and the opening of the first drum corresponds to the first opening 11a.

[0103] In some embodiments, the multi-drum washing machine includes a second drum disposed inside the housing 1, and the opening of the second drum corresponds to the second opening 11b.

[0104] In some embodiments, the multi-drum washing machine includes a third drum disposed within the housing 1, and the opening of the third drum corresponds to the third opening 12a.

[0105] This horizontal arrangement of the two openings helps to optimize the placement of the two drum openings within the limited front panel area, resulting in a more compact overall design for the washing machine. The two smaller drums at the top can be used to wash small items of clothing, while the larger drum at the bottom can be used to wash larger items such as blankets and quilts. The three drums can operate simultaneously, improving the washing machine's cleaning efficiency.

[0106] In some embodiments, the multi-drum washing machine includes a drive assembly disposed within the housing 1. The drive assembly is connected to the first drum, the second drum, and the third drum respectively to drive the first drum, the second drum, and the third drum to rotate, thereby increasing the contact area between the clothes and water and detergent, and thus cleaning the clothes.

[0107] In some embodiments, a multi-drum washing machine includes a first door 2, which is disposed at a first opening 11a to open or close the first opening 11a. The intersection of the axis of the first drum and the outer surface of the first door 2 is the first intersection point. When a user wants to wash clothes, he / she can open the first door 2, put the clothes into the first drum through the first opening 11a, and then close the first door 2.

[0108] In some embodiments, the second door 3 is disposed at the second opening 11b to open or close the second opening 11b. The intersection of the axis of the second roller and the outer surface of the second door 3 is the second intersection point, which is located on the same horizontal plane as the first intersection point. When a user wants to wash clothes, they can open the second door 3, put the clothes into the second roller through the second opening 11b, and then close the second door 3.

[0109] In some embodiments, the third door 4 is disposed at the third opening 12a to open or close the third opening 12a, and the intersection of the axis of the third roller and the outer surface of the third door 4 is the third intersection point. When a user wants to wash clothes, they can open the third door 4, put the clothes into the third roller through the third opening 12a, and then close the third door 4.

[0110] In some embodiments, the ratio of the height H1 of the upper front panel 11 to the height H2 of the lower front panel 12 in the vertical direction is 0.411 to 0.588, the ratio of the height H1 of the upper front panel 11 to the total height H of the housing 1 is 0.291 to 0.37, and the ratio of the height H2 of the lower front panel 12 to the total height H of the housing 1 is 0.709 to 0.63. Here, the height H1 of the upper front panel 11 refers to the vertical distance between two opposite sides of the upper front panel 11 in the vertical direction; the height H2 of the lower front panel 12 refers to the vertical distance between two opposite sides of the lower front panel 12 in the vertical direction.

[0111] It should be noted that in all embodiments, the width W1 of the upper front panel 11 and the width W2 of the lower front panel 12 are the same.

[0112] It should also be noted that this utility model enables the design concept of washing different clothes in different washing areas at the same time.

[0113] Technically, this solution is classified as a partitioned washing machine. In the first possible implementation, partitioned washing involves a combination of several drums or washing machines within a single unit, designed to wash different types of clothing simultaneously. For example, washing outerwear and underwear at the same time. In the second possible implementation, unlike tower washing machines with top drying and bottom washing, this type of machine simply separates the washing and drying functions. In the third possible implementation, it differs from washing machines with two identical drums. In the fourth possible implementation, the most obvious feature is the combination of a large drum and a small drum.

[0114] When the ratio of the height H1 of the upper front panel 11 to the height H2 of the lower front panel 12 is less than 0.441 in the vertical direction, the height H1 of the upper front panel 11 is too small. Given a fixed depth of the housing 1 and a fixed width of the front panel in the horizontal direction, the smaller the height H1 of the upper front panel 11, the smaller the space for the first opening 11a and the second opening 11b, and the smaller the area of ​​the drum opening. Therefore, when the depth of the first and second drums is fixed, the internal space of the first and second drums will be smaller. Since the first and second drums are typically used for washing small items of clothing, this will result in a small number of small items of clothing being washed at once, leading to low washing efficiency. Furthermore, correspondingly, if the height of the lower front panel is too high, and the two upper small drums and the lower large drum are detachable, it will be difficult to remove and place the upper two drums of the washing machine, and it will also be inconvenient to remove and place clothes into the upper small drums.

[0115] When the ratio of the height H1 of the upper front panel 11 to the height H2 of the lower front panel 12 is greater than 0.588, the height H2 of the lower front panel 12 is too small. Given a fixed depth of the housing 1 and a fixed width of the front panel in the horizontal direction, the smaller the height H2 of the lower front panel 12, the smaller the space for the third opening 12a, and the smaller the area of ​​the third roller's opening. Therefore, when the depth of the third roller is fixed, the internal space of the third roller will be smaller. Since the third roller is typically used for washing large items such as blankets, quilts, and coats, this can prevent some oversized items from fitting into the large roller, limiting its applicability. Furthermore, users may need to bend over excessively when loading and unloading clothes, resulting in a poor user experience.

[0116] Therefore, being within this range ensures both the washing efficiency of the small tub and the applicability of the large tub, making it more convenient for users to take out and put out clothes from either the small or large tub, thus enhancing the user experience.

[0117] In some embodiments, combined with Figure 2 In the vertical direction, the ratio of the height H1 of the upper front plate 11 to the height H2 of the lower front plate 12 is 0.432 to 0.648.

[0118] In this way, the height of the upper front panel 11 is close to half the height H2 of the lower front panel 12. The space where the two small drums are located is not too small, which would result in too few small items of clothing being washed at one time. At the same time, the space where the large drum is located is spacious enough to meet the larger space required for large items of clothing during the washing process. This further ensures the washing efficiency of the upper small drums and the applicability of the large drum, making it more convenient for users to take out and put out clothes in the small drums or the large drums, thus enhancing the user experience.

[0119] In some embodiments, combined with Figure 2 In the vertical direction, the height H1 of the upper front plate 11 is 350mm to 500mm.

[0120] In some embodiments, the height H2 of the lower front panel 12 is 616mm to 924mm.

[0121] Specifically, for ease of explanation, the width W1 of the upper front panel 11 and the width W2 of the lower front panel 12 are the same in all embodiments, and are all 595mm as an example.

[0122] When the height H1 of the upper front panel 11 is too small and the height H2 of the lower front panel 12 is too large, given a fixed depth of the housing 1 and a fixed width of the front panel along the horizontal direction, a smaller height H1 of the upper front panel 11 results in a smaller internal space for the first and second rollers, leading to a smaller number of small items of clothing that can be washed at once and low washing efficiency. Conversely, when the height H2 of the lower front panel 12 is too small, given a fixed depth of the housing 1 and a fixed width of the front panel along the horizontal direction, a smaller height H2 of the lower front panel 12 results in a smaller internal space for the third roller, preventing larger items from being placed in the larger drum and limiting its applicability. When the heights H1 of the upper front panel 11 and H2 of the lower front panel 12 are within this range, both the washing efficiency of the upper smaller drum and the applicability of the larger drum are ensured, making it more convenient for users to retrieve clothing from both the smaller and larger drums, thus enhancing the user experience.

[0123] Understandably, due to renovation requirements, the width of drum washing machines is generally fixed in the industry. This invention's twin-tub design, with two tubs placed side-by-side above the main drum washing machine and having the same width as the lower drum, achieves a height range of 350mm-500mm. This meets industry standards and realizes a novel design for a twin-tub washing machine. If the height is greater than this range, the diameter of the two tubs cannot be increased due to the overall machine width limitation, resulting in low internal space utilization and increased cost of the shock absorption system. If the height is less than this range, the reduced overall height of the twin-tub washing machine will compress the internal space, further reducing the diameter of the tubs. Since drum washing machines clean clothes by tumbling them from top to bottom, a smaller tub diameter prevents sufficient tumbling, significantly reducing the washing efficiency and making it unsuitable for washing underwear, socks, and similar items.

[0124] In some embodiments, combined with Figure 3 , Figure 3 This is a schematic diagram of the structure of the upper front panel 11 disclosed in an embodiment of this application. Both the first door 2 and the second door 3 are circular with the same diameter. Circular doors have a larger area for the same perimeter compared to other shapes (such as squares). When both the first door 2 and the second door 3 are circular with the same diameter, they can provide a larger opening area within a limited space. This makes it more convenient for users to load and unload clothes for devices that require frequent entry and exit (such as washing machines), and also improves the utilization rate of the internal space of the device.

[0125] In some embodiments, the ratio of the diameter D1 of the first door body 2 to the height H1 of the upper front plate 11 in the vertical direction is 0.432 to 0.648.

[0126] In some embodiments, the ratio of the diameter D1 of the first door body 2 to the width W1 of the upper front plate 11 in the horizontal direction is 0.336 to 0.504.

[0127] Thus, given a fixed depth of the shell 1 and a fixed width of the front panel in the horizontal direction, if the ratio of the diameter D1 of the first door 2 to the height H1 of the upper front panel 11 is too small, or if the ratio of the diameter D1 of the first door 2 to the width W1 of the upper front panel 11 is too small, the first door 2 will be too small, and the corresponding opening will be too small, making it inconvenient to place clothes.

[0128] Furthermore, if the ratio of the diameter D1 of the first door 2 to the height H1 of the upper front panel 11 is too small, it may be because the height H1 of the upper front panel 11 is too high. This would result in the upper front panel 11 occupying too much space, leading to wasted space. Moreover, if the upper front panel 11 is too large, disassembling and assembling the twin-tub washing machine would be inconvenient, especially if the two smaller tubs at the top are detachable and usable independently. Similarly, if the ratio of the diameter D1 of the first door 2 to the width W1 of the upper front panel 11 is too small, it may be because the width W1 of the upper front panel 11 is too wide. This would also cause the upper front panel 11 to occupy too much width space, resulting in wasted space. Furthermore, the excessive size of the upper front panel 11 not only makes disassembling and assembling the twin-tub washing machine inconvenient but also affects its usability. The excessive width of the multi-tub washing machine 100 means it can only be placed in a space with sufficient width, impacting the user experience.

[0129] If the ratio of the diameter D1 of the first door body 2 to the height H1 of the upper front panel 11 is too large, or if the ratio of the diameter D1 of the first door body 2 to the width W1 of the upper front panel 11 is too large, it means that the first door body 2 is too large, resulting in the first door body 2 being too heavy, difficult to transport, and inconvenient for users to open the door and perform other operations.

[0130] In addition, if the ratio of the diameter D1 of the first door 2 to the height H1 of the upper front panel 11 is too large, or the ratio of the diameter D1 of the first door 2 to the width W1 of the upper front panel 11 is too large, the door will occupy too much space, which will also result in too little space for other components on the upper front panel 11 (such as control knobs), making the space layout of the washing machine unreasonable and affecting the user experience.

[0131] Therefore, within this range, the size of the first door 2 is appropriate, ensuring the convenience of placing clothes and opening and closing the door. The layout of each component on the upper front panel 11 is more reasonable, reducing the waste of space on the upper front panel 11 and enhancing the user experience.

[0132] In some embodiments, combined with Figure 3 In the vertical direction, the diameter D1 of the first door body 2 is 199mm to 299mm.

[0133] In some embodiments, the height H1 of the upper front plate 11 in the vertical direction is 350mm to 500mm.

[0134] With a fixed width W1 for the upper front panel 11 and a fixed height H1 within this range, the dimensions of the first door 2 are more reasonable within this range, ensuring the convenience of placing clothes and opening and closing the door. The layout of each component on the upper front panel 11 is more reasonable, further reducing the waste of space on the upper front panel 11 and enhancing the user experience.

[0135] In some embodiments, combined with Figure 4 , Figure 4 This is a schematic diagram of the structure of the lower front panel 12 disclosed in the embodiment of this application. The third door 4 is a circular door. In the vertical direction, the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 is 0.496 to 0.744.

[0136] In some embodiments, the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front plate 12 in the horizontal direction is 0.712 to 0.96.

[0137] Thus, when the width W2 of the lower front panel 12 is constant and the height H2 of the lower front panel 12 is constant, if the ratio of the diameter D3 of the third door body 4 to the height H2 of the lower front panel 12 is too small or the ratio of the diameter D3 of the third door body 4 to the width W2 of the lower front panel 12 is too small, it means that the area of ​​the third door body 4 is too small, and the corresponding opening is too small, making it inconvenient to place large items.

[0138] Furthermore, when the diameter D3 of the third door 4 is fixed, if the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 is too small, it means that the height H2 of the lower front panel 12 is too high. If the two upper small drums and the lower large drum are detachable, it will be difficult to take the upper two drums of the washing machine in place, and it will also be inconvenient to take clothes into the upper small drums. If the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front panel 12 is too small, it means that the width W2 of the lower front panel 12 is too large, causing it to be placed in a space with sufficient width, which affects the user's experience.

[0139] If the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 is too large, or the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front panel 12 is too large, it means that the third door 4 is too large, resulting in the third door 4 being too heavy, difficult to transport, and inconvenient for users to open the door and perform other operations.

[0140] In addition, when the diameter D3 of the third door 4 is fixed, if the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 or the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front panel 12 is too large, it means that the height H2 of the lower front panel 12 is too small, the door occupies too much space, and it will also lead to too little space for other components on the lower front panel 12 (such as control knobs), resulting in an unreasonable space layout of the washing machine and affecting the user experience.

[0141] Therefore, within this range, the size of the third door 4 is appropriate, ensuring the convenience of placing large items and opening and closing the door. The layout of each component on the lower front panel 12 is more reasonable, further reducing the space waste of the upper front panel 11 and enhancing the user experience.

[0142] In some embodiments, combined with Figure 4 In the vertical direction, the diameter D3 of the third door body 4 is 415mm to 548mm.

[0143] In some embodiments, the height H2 of the lower front plate 12 in the vertical direction is 616mm to 924mm.

[0144] Thus, when the width W2 of the lower front panel 12 is fixed, and the height H2 of the lower front panel 12 takes a fixed value within this range, if the diameter D3 of the third door 4 is too small, the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 is too small, or the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front panel 12 is too small, the area of ​​the third door 4 is too small, and the corresponding opening is too small, making it inconvenient to place large items. If the diameter D3 of the third door 4 is too large, the ratio of the diameter D3 of the third door 4 to the height H2 of the lower front panel 12 is too large, or the ratio of the diameter D3 of the third door 4 to the width W2 of the lower front panel 12 is too large, the third door 4 is too large, resulting in the third door 4 being too heavy, difficult to transport, and inconvenient for users to open the door and perform other operations. Therefore, within this range, the size of the third door 4 is appropriate, ensuring both the convenience of placing large items and opening and closing the door. The layout of each component on the lower front panel 12 is more reasonable, further reducing the waste of space on the upper front panel 11 and enhancing the user experience.

[0145] In some embodiments, combined with Figure 5 , Figure 5 The diagram shows the dimensions of the first door 2, the second door 3, and the third door 4 as disclosed in the embodiments of this application. The first door 2, the second door 3, and the third door 4 are all circular doors, and the diameter D2 of the first door 2 and the second door 3 is the same.

[0146] In some embodiments, the ratio of the diameter D1 of the first door body 2 to the diameter D3 of the third door body 4 is 0.376 to 0.564.

[0147] In some embodiments, the ratio of the diameter D2 of the second door body 3 to the diameter D3 of the third door body 4 is 0.376 to 0.564.

[0148] When the width, height, and depth of the front panel are constant, if the ratio of the diameter D1 of the first door 2 to the diameter D3 of the third door 4 is too small, the size difference between the first door 2 and the third door 4 will be too large, resulting in a visually uncoordinated appearance. If the ratio of the diameter D1 of the first door 2 to the diameter D3 of the third door 4 is too large, the diameters D3 of the first door 2 and the third door 4 will be close, making it difficult for users to distinguish between the large and small tubs, and the functional division of washing small and large items between the large and small tubs is not clear. Therefore, within this range, not only is visual harmony ensured, but the distinction between the large and small tubs is also clearly defined, enhancing the user experience.

[0149] In some embodiments, combined with Figure 5 The diameter D1 of the first door body 2 is 200mm to 281mm.

[0150] In some embodiments, the diameter D2 of the second door body 3 is 200mm to 281mm.

[0151] In some embodiments, the diameter D3 of the third door body 4 is 415mm to 548mm.

[0152] Thus, when the width, height, and depth of the front panel are constant, if the diameter D1 of the first door 2 is too small or the diameter D3 of the third door 4 is too large, the significant size difference between the first door 2 and the third door 4 will result in a visually uncoordinated appearance. Conversely, if the diameter D1 of the first door 2 is too large and the diameter D3 of the third door 4 is too small, the diameters D3 of the first door 2 and the third door 4 will be close, making it difficult for users to distinguish between the large and small tubs, and the functional division between washing small and large items is not clear. Therefore, within this range, not only is visual harmony ensured, but the distinction between the large and small tubs is also clearly defined, enhancing the user experience.

[0153] In some embodiments, combined with Figure 6 , Figure 6 The diagram shows the dimensions of the touchscreen 5 disclosed in this application. The multi-drum washing machine also includes a touchscreen 5, which is mounted on the upper front panel 11 and located above the first door 2 and the second door 3. The touchscreen 5 is electrically connected to the drive assembly. The touchscreen 5 provides an intuitive user interface, allowing users to personalize settings according to their needs. Users can select different washing programs and adjust parameters (such as water temperature and spin speed) by touching icons or text on the screen. This operation method is more intuitive and convenient than traditional mechanical knobs or buttons.

[0154] In some embodiments, the ratio of the height H3 of the touch screen 5 to the height H1 of the upper front panel 11 in the vertical direction is 0.056 to 0.084. Wherein, the height H3 of the touch screen 5 is the vertical distance between two opposite sides of the touch screen 5 in the vertical direction.

[0155] In some embodiments, the ratio of the width W3 of the touch screen 5 to the width W1 of the upper front panel 11 in the horizontal direction is 0.432 to 0.648.

[0156] When the height H1 and width W1 of the upper front panel 11 are constant, if the ratio of the height H3 of the touch screen 5 to the height H1 of the upper front panel 11 is too small, or if the ratio of the width W3 of the touch screen 5 to the width W1 of the upper front panel 11 is too small, the display area will be too small, resulting in unclear display. When the ratio of the height H3 of the touch screen 5 to the height H1 of the upper front panel 11 is greater than 1, or the ratio of the width W3 of the touch screen 5 to the width W1 of the upper front panel 11 is greater than 0.648, the touch screen 5 will almost extend beyond the edge of the front panel. Therefore, within this range, the display requirements can be met, and the front panel space can be used efficiently.

[0157] In some embodiments, combined with Figure 6 In the vertical direction, the height H3 of the touch screen 5 is 12mm to 88mm, and the height H1 of the upper front panel 11 is 350mm to 500mm.

[0158] In some embodiments, the width W3 of the touch screen 5 is 179mm to 595mm in the horizontal direction.

[0159] When the height H1 of the front panel 11 takes a certain value within this range, if the height H3 of the touch screen 5 is too small or the width W3 of the touch screen 5 is too small, the display area will be too small and the display will be unclear. If the height H3 of the touch screen 5 is too large, it will affect the installation space of other components (such as the third roller). If the width W3 of the touch screen 5 is too large, the touch screen 5 will extend beyond the edge of the front panel. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5-meter range, which can meet the display requirements and does not affect the installation space of other components, thus achieving efficient utilization of the front panel space.

[0160] In some embodiments, combined with Figure 7 , Figure 7 The diagram shows the dimensions of the control knob 6 disclosed in this application. The multi-drum washing machine also includes a control component, which can be the control knob 6 or a control button. For ease of explanation, the control knob 6 is used as an example. The control knob 6 is located on the lower front panel 12 and above the third door 4. The control knob 6 is electrically connected to the drive assembly to control the rotation of the third drum. Users can adjust the washing machine settings by rotating the knob. Users can easily adjust parameters such as washing mode, temperature, and spin speed, making it suitable for users of most ages. It allows users to quickly understand and operate the washing machine without referring to the instruction manual.

[0161] In some embodiments, the ratio of the height H4 of the control knob 6 to the height H2 of the lower front panel 12 in the vertical direction is 0.072 to 0.108. The height H3 of the touchscreen 5 is the maximum vertical distance between two opposite edges of the touchscreen 5 in the vertical direction.

[0162] In some embodiments, the ratio of the width W4 of the control knob 6 to the width W2 of the lower front plate 12 in the horizontal direction is 0.104 to 0.156.

[0163] When the height H2 and width W2 of the lower front panel 12 are constant, if the ratio of the height H4 of the control knob 6 to the height H2 of the lower front panel 12 is less than 0.072 or the ratio of the width W4 of the control knob 6 to the width W2 of the lower front panel 12 is less than 0.104, the control knob 6 will be too small, making it more difficult to rotate and adjust parameters such as washing mode, temperature, and spin speed. If the ratio of the height H4 of the control knob 6 to the height H2 of the lower front panel 12 is greater than 0.108 or the ratio of the width W4 of the control knob 6 to the width W2 of the lower front panel 12 is greater than 0.156, the control knob 6 will be too large, making it inconvenient for users to operate and resulting in a poor user experience. Within this range, users can clearly understand the purpose of the knob, and the size is appropriate, making it easier to adjust parameters by rotating the knob.

[0164] In some embodiments, combined with Figure 7 In the vertical direction, the height H4 of the control knob 6 is 12mm to 100mm, and the height H2 of the lower front plate 12 is 616mm to 924mm.

[0165] In some embodiments, the width W4 of the control knob 6 is 12mm to 101mm in the horizontal direction.

[0166] With a fixed width W2 for the lower front panel 12 and a fixed height H2 within this range, if the height H4 of the control knob 6 is less than 12mm or the width W4 of the control knob 6 is less than 12mm, the control knob 6 becomes too small, making it difficult to rotate and adjust parameters such as washing mode, temperature, and spin speed. If the height H4 of the control knob 6 is greater than 100mm or the width W4 of the control knob 6 is greater than 924mm, the control knob 6 becomes too large, making it difficult for the user to rotate and affecting the user experience. Within this range, the user can clearly understand the purpose of the knob, and the size is appropriate, making it more convenient to adjust parameters by rotating the knob.

[0167] In some embodiments, combined with Figure 8 , Figure 8The diagram shows the dimensions of the detergent storage box 7 disclosed in the embodiments of this application. The multi-drum washing machine also includes a detergent storage box 7, which is disposed inside the housing 1. The detergent storage box 7 has a accommodating space for accommodating detergent. The detergent storage box 7 is movably connected to the lower front plate 12 so that the detergent storage box 7 can be pulled out of the housing 1 or stored inside the housing 1.

[0168] This design makes adding detergent incredibly convenient for users. Unlike traditional washing machines where users might need to bend over to add detergent, users can simply pull out the detergent dispenser 7 to easily add detergent, ensuring a smooth user experience. Furthermore, if detergent residue or dirt accumulates in the dispenser after prolonged use, it can be easily removed for thorough cleaning, maintaining hygiene and contributing to the overall cleanliness of the washing machine.

[0169] In some embodiments, the ratio of the width W5 of the detergent storage box 7 to the height H2 of the lower front panel 12 in the vertical direction is 0.112 to 0.168.

[0170] In some embodiments, the ratio of the width W5 of the detergent storage box 7 to the width W2 of the lower front panel 12 in the horizontal direction is 0.328 to 0.492.

[0171] Because the soap dish has a limited depth, and the width of the detergent storage box 7 is fixed horizontally, the vertical volume of the detergent storage box 7 is too small if the ratio of its height H5 to the height H2 of the lower front panel 12 is less than 0.112 or the ratio of its width W5 to the width W2 of the lower front panel 12 is less than 0.328. This would prevent it from holding enough detergent for the machine's rated washing capacity. Conversely, if the ratio of its height H5 to the height of the front panel is greater than 0.168 or the ratio of its width W5 to the width W2 of the lower front panel 12 is greater than 0.492, the volume of the detergent storage box 7 is too large, wasting internal space. Therefore, within this range, the internal space of the washing machine should be utilized efficiently while ensuring sufficient detergent capacity, avoiding space waste caused by an excessively wide soap dish, and allowing enough space for other components (such as the drum and drive assembly).

[0172] In some embodiments, combined with Figure 8 In the vertical direction, the height H5 of the detergent storage box 7 is 75mm to 332mm, and the height H2 of the lower front panel 12 is 616mm to 924mm.

[0173] In some embodiments, the width W5 of the detergent storage box 7 is 119 mm to 298 mm in the horizontal direction.

[0174] When the width W2 of the lower front panel 12 is fixed, and the height H2 of the lower front panel 12 takes a certain value within this range, in the vertical direction, if the height H5 of the detergent storage box 7 is less than 75mm or the width W5 of the detergent storage box 7 is less than 119mm, the volume of the detergent storage box 7 is too small and cannot hold enough detergent corresponding to the rated washing capacity of the whole machine. In the horizontal direction, if the height H5 of the detergent storage box 7 is greater than 332mm or the width W5 of the detergent storage box 7 is greater than 298mm, the volume of the detergent storage box 7 is too large, which will waste the internal space of the casing 1. Therefore, within this range, while meeting the requirement of accommodating enough detergent, the internal space of the washing machine should be rationally utilized to avoid the waste of space caused by an excessively wide soap dish, so that the internal space of the washing machine can leave enough space for other components (such as the drum, drive assembly, etc.).

[0175] In some embodiments, combined with Figure 9 , Figure 9 This is a dimension marking diagram showing the distance between the intersection points of the door body disclosed in the embodiments of this application. The distance L1 between the first intersection point and the third intersection point is equal to the distance L2 between the second intersection point and the third intersection point.

[0176] The distances L1 between the first and third intersection points, L2 between the second and third intersection points, and the distance between the first and second intersection points can form an isosceles triangle or an equilateral triangle. This shape has higher stability. When the drum rotates and there is an eccentric load, the eccentricity can be more easily offset with the cooperation of each drum, ensuring the balanced vibration reduction performance of the entire three-drum system, and thus ensuring the stability of the entire washing machine.

[0177] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
