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 can ensure users can easily take out clothes from both drums during use without wasting space.

[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] A front panel, wherein a first opening and a second opening are provided on the front panel, and the first opening and the second opening are arranged side by side in the horizontal direction;

[0008] A first roller is disposed inside the housing, and the opening of the first roller corresponds to the first opening;

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

[0010] A drive assembly is disposed within the housing, and the drive assembly is respectively connected to the first roller and the second roller to drive the first roller and the second roller to rotate;

[0011] 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;

[0012] 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.

[0013] In the vertical direction, the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel is 0.4 to 0.6.

[0014] Therefore, when the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel is greater than 0.6, it means that the positions of the first and second doors are too low. This may result in excessive occupation of the space below the washing machine interior, and require excessive bending over when loading and unloading clothes, making it inconvenient to place and retrieve them. Furthermore, the corresponding first drum will also be set too low, resulting in an excessively long suspension arm connecting the first drum to the top panel. The connection strength of the suspension arm is low, and the stability of the suspension arm is not good enough when the first drum rotates, which may lead to structural damage to the suspension arm.

[0015] Additionally, when this multi-drum washing machine is used in conjunction with another front-drum washing machine, the two upper drums are positioned too close to the lower drum. In this situation, when the rotational speeds of the two upper drums are similar to those of the lower drum, resonance can easily occur, affecting the overall lifespan of the machine.

[0016] When the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel is less than 0.4, it means the door is positioned too high. This may result in excessive occupation of the upper space inside the washing machine, making it impossible to fully utilize the upper space for the proper layout of other components, such as the detergent dispenser, control knobs, and electrical wiring. Additionally, the corresponding first drum will be set too high, causing the washing machine's center of gravity to be too high. When the drum rotates, the washing machine is prone to excessive vibration and generates significant noise.

[0017] When the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel is between 0.4 and 0.6, there is sufficient space to accommodate the detergent dispenser, control knobs, and electrical wiring, ensuring user convenience and comfort. During drum rotation, this ratio range ensures stability not only for the suspension arms and other structural components but also for the overall stability of the washing machine, due to the drum's optimal position and center of gravity.

[0018] As an optional implementation, the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel in the vertical direction is 0.475 to 0.525.

[0019] In this way, the first intersection point is close to the middle of the front panel height, making the door position more reasonable and further optimizing the layout of the washing machine's internal space, reducing unnecessary space waste. This not only improves the space utilization rate of the washing machine but also helps to reduce its overall size, making it more suitable for placement in different home environments. Moreover, because the height of the first intersection point is moderate and the position of the first drum is also moderate, the stability of structures such as the hanging arm and the overall stability of the washing machine are better.

[0020] As an optional implementation, the distance from the first intersection point to the top of the front plate in the vertical direction is 100mm to 300mm.

[0021] Therefore, if the height and width of the front panel are fixed, and the distance from the first intersection point to the top of the front panel is less than 100mm, the door position will be too high. This may result in excessive occupation of the upper space inside the washing machine, making it impossible to fully utilize the upper space for the reasonable layout of other components, such as the detergent dispenser, control knobs, and electrical wiring. Moreover, the corresponding first drum will also be set too low, resulting in an excessively long suspension arm connecting the first drum and the top panel. The connection strength of the suspension arm will be low, and the stability of the suspension arm will be insufficient when the first drum rotates, potentially leading to structural damage to the suspension arm.

[0022] When the distance from the first intersection point to the top of the front panel is greater than 300mm, it means that the positions of the first and second doors are too low. This may result in excessive occupation of the lower space inside the washing machine, and require excessive bending over when loading and unloading clothes, making it inconvenient to place and retrieve them. In addition, the corresponding first drum will be set too high, resulting in a higher center of gravity for the washing machine. When the drum rotates, the washing machine is prone to excessive vibration and generates more noise.

[0023] Therefore, the distance from the first intersection point to the top of the front panel is 100mm to 300mm. This allows for easy removal of clothes from both drums while providing sufficient space for the detergent dispenser, control knobs, and electrical wiring, ensuring user convenience and comfort. This range of values ​​not only guarantees the stability of the suspension arms and other structures during drum rotation but also ensures the overall stability of the washing machine, extending its lifespan.

[0024] As an optional implementation, the multi-drum washing machine further includes:

[0025] A control knob is disposed on the outer surface of the housing and is electrically connected to the drive assembly.

[0026] In this way, users can directly control the operation of the washing machine through the control knob, such as starting, pausing, and selecting washing modes, simplifying the operation process.

[0027] As an optional implementation, the multi-drum washing machine includes a control knob disposed on the front panel. In the vertical direction, the ratio of the distance between the center point of the outer end face of the control knob and the first intersection point to the height of the front panel is 0.32 to 0.48. The center point of the outer end face of the control knob is the intersection point of the rotation axis of the control knob and the outer end face of the control knob.

[0028] Along the horizontal direction, the ratio of the distance from the center point of the outer end face of the control knob to one side of the front panel to the width of the front panel is 0.4 to 0.5.

[0029] In this way, users can adjust the washing machine settings by rotating the knob, making it easy for them to quickly understand and operate the machine. When the ratio of the distance between the center point of the outer end face of the control knob and the first intersection point to the height of the front panel is less than 0.32, or the ratio of the distance from the center point of the outer end face of the control knob to one side of the front panel to the width of the front panel is less than 0.4, the space available for wiring around the control knob will be severely compressed. When the ratio of the distance between the center point of the outer end face of the control knob and the first intersection point to the height of the front panel is greater than 0.48, the connection line between the control knob and the drum is excessively long, occupying too much space. Therefore, when the ratio is within this range, it can effectively ensure that there is adequate space around the knob for wiring layout without affecting the setting space of other structures.

[0030] As an optional implementation, the distance between the center point of the outer end face of the control knob and the first intersection point in the vertical direction is 100mm to 192mm;

[0031] Along the horizontal direction, the distance from the center point of the outer end face of the control knob to one side of the front panel is 1mm to 297.5mm.

[0032] When the height and width of the front panel are fixed, in the vertical direction, if the distance between the center point of the outer end face of the control knob and the first intersection point is less than 100mm, the space around it for wiring will be severely compressed. If the distance is greater than 192mm, the connection line between the control knob and the door body becomes excessively long, occupying too much space. Therefore, within this range, it is possible to ensure adequate space around the knob for wiring, without affecting the installation space of other structures. In the horizontal direction, the distance from the center point of the outer end face of the control knob to one side of the front panel should be between 1mm and 297.5mm. This effectively prevents the control knob from being too close to the horizontal edge of the housing, ensuring sufficient space around the knob for wiring.

[0033] As an optional implementation, the multi-drum washing machine includes a control knob, and the housing further includes:

[0034] Top plate, which is connected to the top of the front plate;

[0035] The control knob is disposed on the top plate. Along the first horizontal direction, the ratio of the distance from the center point of the outer end face of the control knob to one side of the top plate to the width of the top plate is 0.03 to 0.5. The first horizontal direction is the horizontal extension direction of the front plate.

[0036] Thus, with the control knob located on the top panel, users can easily observe the corresponding options by looking down. When the ratio of the distance from the center point of the outer end face of the control knob to one side of the top panel to the width of the top panel is less than 0.03, the control knob may be too close to one edge of the front panel. This severely compresses the space around it for wiring, leaving insufficient space for the control knob and affecting ease of operation. Therefore, within this range, it is possible to effectively avoid placing the control knob too close to the horizontal sides of the housing, ensuring sufficient space around the knob for wiring and other layout purposes.

[0037] As an optional implementation, the multi-drum washing machine includes a touch screen, which is disposed on the front panel in the vertical direction, and the ratio of the height of the touch screen to the height of the front panel is 0.064 to 0.084.

[0038] Along the horizontal direction, the ratio of the width of the touch screen to the width of the front panel is 0.432 to 0.567.

[0039] In this way, the touchscreen can provide an intuitive user interface, allowing users to personalize settings according to their needs. Vertically, if the ratio of the touchscreen height to the front panel height is too small, or horizontally, if the ratio of the touchscreen width to the front panel width is too small, the display area will be too small, resulting in unclear display. If the ratio of the touchscreen height to the front panel height is too large, the display area will be too large, leading to wasted space and costs. If the ratio of the touchscreen width to the front panel width is too large, it will almost exceed the edge of the front panel. Therefore, within this range, display requirements are met without excessively encroaching on the space of other components, achieving efficient use of the front panel space.

[0040] As an optional implementation, the height of the touch screen is 12mm to 88mm in the vertical direction;

[0041] The width of the touch screen is 170mm to 595mm in the horizontal direction.

[0042] Therefore, with a fixed height and width of the front panel, if the touchscreen height is less than 12mm vertically, or the touchscreen width is less than 170mm horizontally, the display area will be too small, resulting in unclear display. If the touchscreen height is greater than 88mm or the touchscreen width is greater than 595mm, the display area will be too large or extend beyond the front panel edge, leading to wasted space and cost. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5-meter radius, satisfying display requirements without excessively encroaching on the space of other components, thus achieving efficient use of the front panel space.

[0043] As an optional implementation, the multi-drum washing machine includes a touch screen, which is disposed on the first door and / or the second door. The first door and the second door are both circular doors with the same diameter. In the horizontal direction, the ratio of the width of the touch screen to the diameter of the first door is 0.4 to 0.525.

[0044] In the vertical direction, the ratio of the height of the touch screen to the diameter of the first door body is greater than or equal to 0.4 to 0.525.

[0045] Thus, placing the touchscreen on the door saves space on the front panel of the washing machine, making the overall design more compact. It also frees up more space for other components (such as control knobs and detergent dispensers), optimizing the overall layout. If the ratio of the touchscreen width to the diameter of the first door is too small, or if the ratio of the touchscreen height to the diameter of the first door is too small vertically, the display area may be too small and unclear. If the ratio of the touchscreen width to the diameter of the first door is too large, the touchscreen may extend beyond the door's edge. Therefore, within this range, display requirements are met while achieving efficient use of the front panel space.

[0046] As an optional implementation, the width of the touch screen is greater than or equal to 10mm in the horizontal direction, and the diameter of the first door body is 200mm to 380mm.

[0047] The height of the touch screen is greater than or equal to 10mm in the vertical direction.

[0048] In this way, the display area can be clearly seen by the naked eye within a range of 1.5m, which can meet the display requirements and achieve efficient use of the front panel space. The height of the touch screen can be adjusted accordingly with its width.

[0049] As an optional implementation, the multi-drum washing machine includes a touch screen, and the housing further includes:

[0050] Top plate, which is connected to the top of the front plate;

[0051] The touch screen is disposed on the top plate. Along the first horizontal direction, the ratio of the width of the touch screen to the width of the top plate is 0.432 to 0.567. The first horizontal direction is the horizontal extension direction of the front plate.

[0052] Along the second horizontal direction, the ratio of the height of the touch screen to the height of the top plate is 0.072 to 0.095, and the second horizontal direction is perpendicular to the first horizontal direction.

[0053] Therefore, placing the touchscreen on the top panel brings its display area closer to the user's line of sight, allowing them to easily view the screen by looking down, thus improving visibility. If the ratio of the touchscreen's width to the top panel's width is too small along the first horizontal direction, or if the ratio of the touchscreen's height to the top panel's height is too small along the second horizontal direction, the display area will be too small, resulting in unclear display. If the ratio of the touchscreen's width to the top panel's length is too large, the touchscreen may extend beyond the top panel's edge. If the ratio of the touchscreen's height to the top panel's height is too large, the display area will be too large, leading to wasted space and cost. Therefore, within this range, display requirements are met, achieving efficient utilization of the front panel space.

[0054] As an optional implementation, the width of the touch screen along the first horizontal direction is 50mm to 407mm;

[0055] Along the second horizontal direction, the height of the touch screen is 10mm to 150mm.

[0056] Thus, when the height and width of the top panel are constant, if the touchscreen width is less than 50mm along the first horizontal direction, or the touchscreen height is less than 10mm along the second horizontal direction, the display area is easily too small, resulting in unclear display. If the touchscreen width is greater than 407mm or the touchscreen height is greater than 150mm, the touchscreen extends beyond the edge of the top panel, or the display area becomes too large, easily leading to wasted space and cost. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5m radius, satisfying display requirements without excessively encroaching on the space of other components, achieving efficient utilization of the front panel space.

[0057] As an optional implementation, the multi-drum washing machine further includes:

[0058] 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 housing so that it can be pulled out of the housing or stored inside the housing.

[0059] 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. Furthermore, if detergent residue or dirt accumulates in the dispenser after long-term use, it can be easily pulled out for thorough cleaning, keeping the dispenser clean and hygienic, which in turn helps maintain the overall cleanliness of the washing machine.

[0060] As an optional implementation, the detergent storage box is movably connected to the front panel, and the ratio of the height of the detergent storage box to the height of the front panel in the vertical direction is 0.12 to 0.158.

[0061] Along the first horizontal direction, the ratio of the width of the detergent storage box to the width of the front panel is 0.32 to 0.42, and the first horizontal direction is the horizontal extension direction of the front panel.

[0062] Therefore, due to the limited depth of the soap dish, if the ratio of the height of the detergent dispenser to the height of the front panel is too small, or if the ratio of the width of the detergent dispenser to the width of the front panel is too small, the volume of the detergent dispenser will be too small to hold enough detergent for the rated washing capacity of the machine. Conversely, if the ratio of the height of the detergent dispenser to the height of the front panel is too large, or if the ratio of the width of the detergent dispenser to the width of the front panel is too large, the volume of the detergent dispenser will be too large, wasting internal space. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be used efficiently to avoid wasting space due to an excessively wide soap dish, allowing sufficient space inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0063] As an optional implementation, the height of the detergent storage box in the vertical direction is 20mm to 150mm;

[0064] Along the first horizontal direction, the width of the detergent storage box is 50mm to 300mm.

[0065] Because of the limited depth of the soap dish, if the height of the detergent storage box is less than 20mm or the width is less than 50mm, the volume of the detergent storage box is too small to hold enough detergent for the rated washing capacity of the machine. If the height of the detergent storage box is greater than 150mm or the width is greater than 300mm, the volume of the detergent storage box is too large, wasting internal space. Therefore, within this range, the internal space of the washing machine should be used rationally while ensuring sufficient detergent capacity, avoiding space waste caused by an excessively wide or high soap dish.

[0066] As an optional implementation, the housing further includes:

[0067] Top plate, which is connected to the top of the front plate;

[0068] The detergent storage box is movably connected to the top plate. Along the first horizontal direction, the ratio of the width of the detergent storage box to the width of the top plate is 0.32 to 0.42. The first horizontal direction is the horizontal extension direction of the front plate.

[0069] Along the second horizontal direction, the ratio of the height of the detergent storage box to the height of the top plate is 0.28 to 0.368, and the second horizontal direction is perpendicular to the first horizontal direction.

[0070] Thus, the detergent dispenser is movably connected to the top plate, allowing users to easily bend down and open the lid to add detergent. However, due to the limited depth of the soap dish, if the ratio of the detergent dispenser's width to the top plate's width is too small, or the ratio of the detergent dispenser's height to the top plate's height is too small, the dispenser's volume will be too small to hold enough detergent for the machine's rated washing capacity. Conversely, if the ratio of the detergent dispenser's width to the top plate's width, or the ratio of the detergent dispenser's height to the top plate's height, is too large, the dispenser's volume will be too large, wasting internal space. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be used 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 width of the detergent storage box along the first horizontal direction is 50mm to 300mm;

[0072] Along the second horizontal direction, the height of the detergent storage box is 20mm to 300mm.

[0073] Because the soap dish has limited depth, if the width of the detergent storage box is less than 50mm or the height is less than 20mm, the volume of the detergent storage box is too small to hold enough detergent for the rated washing capacity of the machine. If the width of the detergent storage box is greater than 300mm or the height is greater than 300mm, the volume of the detergent storage box is too large, wasting internal space. Therefore, within this range, the internal space of the washing machine should be used rationally while ensuring sufficient detergent capacity, avoiding space waste caused by an excessively wide soap dish.

[0074] Compared with the prior art, the beneficial effects of this application are:

[0075] The multi-drum washing machine provided in this application embodiment, when the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel is between 0.4 and 0.6, provides sufficient space for arranging a detergent dispenser, control knobs, and electrical wiring, ensuring user convenience and comfort during use. This ratio range not only ensures the stability of the suspension arms and other structures during drum rotation but also guarantees the overall stability of the washing machine.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Multi-drum washing machines present a challenge due to the difficulty in arranging multiple drums in a reasonable manner.

[0099] Based on this, this application discloses a multi-drum washing machine, wherein the ratio of the distance from the first intersection point to the top of the front panel to the height of the front panel in the vertical direction is 0.45 to 0.55, which can ensure that the user can easily take out the clothes in the two drums during use without wasting space.

[0100] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0101] 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 of the front panel 11 of a multi-drum washing machine disclosed in an embodiment of this application. This application discloses a multi-drum washing machine.

[0102] 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.

[0103] In some embodiments, the housing 1 includes a front plate 11, on which a first opening 1a and a second opening 1b are provided, and the first opening 1a and the second opening 1b are arranged side by side in the horizontal direction.

[0104] In some embodiments, a multi-drum washing machine includes a first drum, which is disposed inside the housing 1, and the opening of the first drum corresponds to the first opening 1a.

[0105] 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 1b.

[0106] This horizontal arrangement of the two openings helps to rationally arrange the positions of the two drum openings within the limited area of ​​the front panel 11. It avoids the height increase that might result from stacking openings vertically, making the washing machine more compact and easier to place in space-constrained home environments. Furthermore, when users need to operate both drums simultaneously, such as when adding clothes or detergent, the side-by-side openings allow for simultaneous operation without frequent repositioning. Users can easily switch between the two openings while standing in front of the washing machine, improving operational efficiency.

[0107] 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 and the second drum respectively to drive the first drum and the second drum to rotate, thereby increasing the contact area between the clothes and water and detergent, and thus cleaning the clothes.

[0108] In some embodiments, the multi-drum washing machine includes a first door 2, which is disposed at a first opening 1a to open or close the first opening 1a. 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 1a, and then close the first door 2.

[0109] In some embodiments, the second door 3 is disposed at the second opening 1b to open or close the second opening 1b, and the second intersection point and the first intersection point are located on the same horizontal plane. When a user wants to wash clothes, they can open the second door 3, put the clothes into the second drum through the second opening 1b, and then close the second door 3.

[0110] This design, on the one hand, helps improve the structural stability of the washing machine. Because the two intersection points are on the same horizontal plane, the center of gravity distribution during operation is more even, reducing wobbling or instability caused by a shift in the center of gravity. On the other hand, the door design on the same horizontal plane allows for more efficient use of the internal space. The layout of the two drums can be more compact, reducing unnecessary space waste and making the overall size of the washing machine more reasonable. This also makes it more convenient for users to operate the washing machine. Whether opening the first door 2 or the second door 3, the user's operating height remains consistent, eliminating the need for frequent adjustments to body posture and reducing discomfort during operation.

[0111] In some embodiments, the ratio of the distance H1 from the first intersection point to the top of the front panel 11 to the height H of the front panel 11 in the vertical direction is 0.4 to 0.6. The height H of the front panel 11 refers to the vertical distance between two opposite sides of the front panel 11 in the vertical direction.

[0112] When the ratio of the distance H1 from the first intersection point to the top of the front panel 11 to the height H of the front panel 11 is greater than 0.6, it means that the position of the first door 2 and the second door 3 is too low, which may cause the space below the washing machine to be over-occupied, making it impossible to make full use of the space below to reasonably arrange the drive components, shock absorption components and other components, wasting space, and requiring excessive bending over when taking out and taking out clothes, which is inconvenient for putting out and taking out clothes.

[0113] Furthermore, the corresponding first roller is also set lower, resulting in an excessively long suspension boom connecting the first roller and the top plate 12. The connection strength of the boom is low, and the stability of the boom is not good when the first roller rotates, which may lead to structural damage to the boom.

[0114] Furthermore, when this multi-drum washing machine 100 is used in conjunction with another front-drum washing machine, the two upper drums are positioned too close to the lower large drum. In this situation, when the rotational speeds of the two upper smaller drums are similar to those of the lower large drum, resonance can easily occur, affecting the overall lifespan of the machine.

[0115] Specifically, when two objects have the same or similar natural frequencies, the vibration of one object is more likely to cause the other to resonate. This phenomenon is called resonance, and the amplitude of the vibration increases as the distance decreases. When two objects come into contact and vibrate, energy is exchanged between them. If the two objects have the same or similar natural frequencies, their vibrations will reinforce each other, leading to a significant increase in amplitude. This phenomenon is called resonance in physics and has many applications in daily life, such as the resonating chambers of musical instruments and dampers in buildings. Therefore, when the natural frequencies of the upper drum and the lower drum are similar, the closer they are, the more pronounced the resonance effect and the larger the amplitude, resulting in poor stability of the washing machine.

[0116] When the ratio of the distance H1 from the first intersection point to the top of the front panel 11 to the height H of the front panel 11 is less than 0.4, it means that the door is too high, which may cause the upper space inside the washing machine to be over-occupied and unable to make full use of the upper space to reasonably arrange other components, such as the detergent storage box 5, the control unit 4, and the electrical connection lines.

[0117] In addition, the corresponding first drum is set higher, which makes the center of gravity of the washing machine higher. When the drum rotates, the washing machine is prone to excessive vibration and generates more noise.

[0118] Therefore, when the ratio is within this range, the height of the drum can be matched with the vertical space inside the washing machine. This avoids situations where the top space is too large and cannot be effectively utilized, or the bottom space is wasted due to the drum being too high. It allows for easy removal of clothes from both drums while providing sufficient space for the detergent dispenser, controls, and electrical wiring, ensuring user convenience and comfort. Furthermore, this ratio range not only ensures the stability of the suspension arms and other structures during drum rotation but also guarantees the overall stability of the washing machine, extending its lifespan.

[0119] It is understood that the multi-drum washing machine can be placed on top of a front-drum washing machine, with the same width as the front-drum washing machine, or it can be placed directly on the floor, table, or other surfaces for independent use. This embodiment does not limit this.

[0120] Preferably, combined with Figure 1 and Figure 2 In the vertical direction, the ratio of the distance H1 from the first intersection point to the top of the front plate 11 to the height H of the front plate 11 is 0.475 to 0.525.

[0121] In this way, the first intersection point is located near the middle of the front panel height 11, allowing users to open or close the door without excessive bending or reaching, making operation more natural and comfortable. This design conforms to ergonomic principles, reducing the physical exertion required when using the washing machine. This ratio design makes the door position more reasonable, further optimizing the layout of the washing machine's internal space and reducing unnecessary space waste. This not only improves the space utilization of the washing machine but also helps to reduce its overall size, making it more suitable for placement in different home environments. Moreover, because the height of the first intersection point is moderate and the position of the first drum is also moderate, the stability of structures such as the suspension arm and the overall stability of the washing machine are better.

[0122] In some embodiments, combined with Figure 1 and Figure 2 In the vertical direction, the distance H1 from the first intersection point to the top of the front plate 11 is 100mm to 300mm.

[0123] For ease of explanation, the height H of the front panel 11 in the following embodiments will be 407mm. When the distance H1 from the first intersection point to the top of the front panel 11 is less than 100mm, the door position is too high, which may cause the upper space inside the washing machine to be over-occupied, making it impossible to make full use of the upper space to reasonably arrange other components such as the drum, pipes, detergent storage box, control components, and electrical connection lines.

[0124] Furthermore, the corresponding first drum is set too low, resulting in an excessively long suspension arm connecting the first drum and the top plate 12. This leads to lower connection strength and insufficient stability of the arm during the first drum's rotation, potentially causing structural damage. Additionally, when this multi-drum washing machine 100 is used with another drum washing machine, the two upper drums are too close to the lower large drum. When the rotational speeds of the two upper smaller drums are similar to those of the lower large drum, resonance can easily occur, affecting the overall lifespan of the machine.

[0125] When the distance H1 from the first intersection point to the top of the front panel 11 is greater than 300mm, it means that the position of the first door 2 and the second door 3 is too low, which may cause excessive occupation of the space below the inside of the washing machine, and require excessive bending over when loading and unloading clothes, making it inconvenient to put and take out clothes.

[0126] In addition, the corresponding first drum is set higher, which makes the center of gravity of the washing machine higher. When the drum rotates, the washing machine is prone to excessive vibration and generates more noise.

[0127] Therefore, the distance H1 from the first intersection point to the top of the front panel 11 is 100mm to 300mm. This allows the height of the drum to match the vertical space inside the washing machine, avoiding wasted space and ensuring that users can easily remove clothes from both drums without wasting space, thus ensuring user convenience and comfort. When the drum rotates, this ratio range not only ensures the stability of the suspension arms and other structures but also guarantees the overall stability of the washing machine.

[0128] In some embodiments, combined with Figure 3 and Figure 5 , Figure 3 This is a schematic diagram of the structure of the control knob 41 disclosed in this application, which is disposed on the front panel 11. Figure 5 This is a schematic diagram of the touch screen 42 disposed on the front panel 11 according to an embodiment of this application. The multi-drum washing machine also includes a control component 4, which is disposed on the outer surface of the housing 1 and is electrically connected to the drive assembly, so that the user can directly control the operation of the washing machine through the control component 4, such as starting, pausing, and selecting washing modes, thus simplifying the operation process.

[0129] The placement of control unit 4 integrates all the washing machine's functions into a single, easily accessible location. Users can control multiple functions, such as adjusting washing time, temperature, and spin speed, using a single control unit. This reduces the user's direct contact with the internal moving parts of the washing machine, thereby improving safety.

[0130] In some embodiments, combined with Figure 3 The control element 4 can be a control knob 41 or a control button. For ease of explanation, the control knob 41 is used as an example. The control knob 41 is located on the front panel 11. Users can adjust the washing machine settings by rotating it. Users can easily adjust parameters such as washing mode, temperature, and spin speed. It is suitable for users of most ages and allows users to quickly understand and operate the washing machine without referring to the instruction manual.

[0131] In some embodiments, the ratio of the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point to the height H of the front plate 11 in the vertical direction is 0.32 to 0.48, and the center point of the outer end face of the control knob 41 is the intersection of the rotation axis of the control knob 41 and the outer end face of the control knob 41.

[0132] In the vertical direction, when the ratio of the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point to the height H of the front plate 11 is too small, the control knob 41 is closer to the first door 2 and the second door 3, and the space around the control knob 41 for wiring is severely compressed. When the ratio of the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point to the height H of the front plate 11 is too large, the connection line between the control knob 41 and the roller is lengthy and occupies too much space. Therefore, when the ratio is between 0.32 and 0.48, it can effectively ensure that there is suitable space around the knob for wiring layout without affecting the setting space of other structures.

[0133] In some embodiments, the ratio of the distance W1 from the center point of the outer end face of the control knob 41 to one side of the front plate 11 to the width W of the front plate 11 in the horizontal direction is 0.4 to 0.5.

[0134] In the horizontal direction, when the ratio of the distance W1 from the center point of the outer end face of the control knob 41 to one side of the front panel 11 to the width W of the front panel 11 is too small, the control knob 41 may be too close to one side edge of the front panel 11. This would severely compress the space around the control knob 41 for wiring design, leaving insufficient space for its design and affecting ease of operation. Therefore, within this range, it is possible to effectively prevent the control knob 41 from being too close to either side of the housing 1 in the horizontal direction, ensuring sufficient space around the knob for wiring layout.

[0135] In some embodiments, combined with Figure 3In the vertical direction, the ratio of the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point to the height H of the front plate 11 is 0.4 to 0.5. In this way, there is enough space between the control knob 41 and the first door body 2 to install wiring and other structures, and the wiring will not be too long, thus saving space.

[0136] In some embodiments, combined with Figure 3 In the vertical direction, the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point is 155mm to 171mm.

[0137] In the vertical direction, when the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point is less than 155mm, the control knob 41 is closer to the first door body 2 and the second door body 3, and the space around it for wiring is severely compressed. When the distance H2 between the center point of the outer end face of the control knob 41 and the first intersection point is greater than 171mm, the connection line between the control knob 41 and the door body is lengthy and occupies too much space. Therefore, within this range, it is possible to ensure that there is adequate space around the knob for wiring, etc., without affecting the installation space of other structures.

[0138] In some embodiments, the distance W1 from the center point of the outer end face of the control knob 41 to one side of the front plate 11 in the horizontal direction is 283mm to 312mm.

[0139] For ease of explanation, the width W of the front panel 11 in subsequent embodiments will be 595mm as an example. Horizontally, when the distance W1 from the center point of the outer end face of the control knob 41 to one side of the front panel 11 is less than 283mm, the control knob 41 may be too close to one side edge of the front panel 11. This would severely compress the space around it for wiring design, leaving insufficient space for the control knob 41 and affecting ease of operation. Therefore, within this range, it is possible to effectively avoid the control knob 41 being too close to the horizontal edge of the housing 1, ensuring sufficient space around the knob for wiring layout, etc.

[0140] In some embodiments, combined with Figure 4 , Figure 4 This is a schematic diagram of the structure of the control knob 41 disclosed in the embodiment of this application, which is disposed on the top plate 12. The control component 4 includes the control knob 41, and the housing 1 also includes the top plate 12, which is connected to the top of the front plate 11.

[0141] In some embodiments, the control knob 41 is disposed on the top plate 12, and the ratio of the distance W2 from the center point of the outer end face of the control knob 41 to one side of the top plate 12 to the width W4 of the top plate 12 along the first horizontal direction X is 0.03 to 0.5. The first horizontal direction X is the horizontal extension direction of the front plate 11.

[0142] The control knob 41 is located on the top plate 12, allowing the user to easily observe the corresponding options by looking down. When the ratio of the distance W2 from the center point of the outer end face of the control knob 41 to one side of the top plate 12 to the width W4 of the top plate 12 is less than 0.03, the control knob 41 may be too close to one side edge of the front plate 11. This would severely compress the space around it for wiring design, leaving insufficient space for the control knob 41 and affecting ease of operation. Therefore, within this range, it is possible to effectively avoid the control knob 41 being too close to the horizontal sides of the housing 1, ensuring sufficient space around the knob for wiring layout, etc.

[0143] In some embodiments, combined with Figure 5 The control unit 4 includes a touch screen 42, which is located on the front panel 11. The touch screen 42 provides an intuitive user interface, and users can make personalized settings on the touch screen 42 according to their own needs. Users can select different washing programs and adjust parameters (such as water temperature, spin speed, etc.) by touching the icons or text on the screen. This operation method is more intuitive and convenient than traditional mechanical knobs or buttons.

[0144] In some embodiments, the ratio of the height H3 of the touch screen 42 to the height H of the front panel 11 in the vertical direction is 0.064 to 0.084. Wherein, the height H3 of the touch screen 42 is the vertical distance between two opposite sides of the touch screen 42 in the vertical direction.

[0145] In the vertical direction, if the ratio of the height H3 of the touchscreen 42 to the height H of the front panel 11 is too small, the display area will be too small and the display will be unclear. If the ratio of the height H3 of the touchscreen 42 to the height H of the front panel 11 is too large, the display area of ​​the touchscreen 42 will be too large, which will easily lead to a waste of space and cost. Therefore, within this range, the display requirements can be met without excessively encroaching on the space of other components, thus achieving efficient utilization of the space of the front panel 11.

[0146] In some embodiments, the ratio of the width W3 of the touch screen 42 to the width W of the front panel 11 in the horizontal direction is 0.432 to 0.567.

[0147] Along the horizontal direction, when the ratio of the width W3 of the touchscreen 42 to the width W of the front panel 11 is too small, the display area is easily too small, resulting in unclear display. When the ratio of the width W3 of the touchscreen 42 to the width W of the front panel 11 is too large, it is easy to exceed the edge of the front panel 11. Therefore, within this range, the display requirements can be met, and the space of the front panel 11 is efficiently utilized.

[0148] In some embodiments, combined with Figure 5In the vertical direction, the height H3 of the touch screen 42 is 12mm to 88mm.

[0149] In the vertical direction, when the height H3 of the touchscreen 42 is less than 12mm, the display area is too small and the display is unclear. When the height H3 of the touchscreen 42 is greater than 88mm, the display area of ​​the touchscreen 42 becomes too large, which can lead to a waste of space and cost. Therefore, within this range, the display requirements can be met without excessively encroaching on the space of other components, thus achieving efficient utilization of the front panel 11 space.

[0150] In some embodiments, the width W of the touchscreen 42 in the horizontal direction is 179mm to 595mm. When the width W3 of the touchscreen 42 in the horizontal direction is less than 179mm, the display area is easily too small, resulting in unclear display. When the width W3 of the touchscreen 42 is greater than 595mm, it extends beyond the edge of the front panel 11. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5-meter range, meeting display requirements and achieving efficient utilization of the space on the front panel 11.

[0151] In some embodiments, combined with Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the touch screen 42 disposed in the first door body 2 according to an embodiment of this application. Figure 8 This is a schematic diagram of the structure of the touch screen 42 disclosed in this application, which is disposed on the first door 2 and the second door 3. The control unit 4 includes the touch screen 42, which is disposed on the first door 2 and / or the second door 3, making the operation more intuitive and convenient. When opening or closing the door, the user can operate directly on the door without having to look for the control panel, thus improving the user experience. In addition, it can save space on the front panel 11 of the washing machine, making the overall design of the washing machine more compact, and also leaving more space for other components (such as the control knob 41, detergent storage box 5, etc.), which is conducive to the optimization of the overall layout.

[0152] In some embodiments, both the first door 2 and the second door 3 are circular and have the same diameter. A circular door has a larger area for the same perimeter compared to other shapes (such as a square). When both the first door 2 and the second door 3 are circular and have 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.

[0153] In some embodiments, the ratio of the width W3 of the touch screen 42 to the diameter D of the first door 2 in the horizontal direction is 0.4 to 0.525.

[0154] Along the horizontal direction, when the ratio of the width W3 of the touchscreen 42 to the diameter D of the first door 2 is too small, the display area is easily too small, resulting in unclear display. When the ratio of the width W3 of the touchscreen 42 to the diameter D of the first door 2 is too large, the touchscreen 42 will extend beyond the edge of the door. Therefore, within this range, the display requirements can be met, achieving efficient utilization of the front panel 11 space.

[0155] In some embodiments, the ratio of the height H3 of the touch screen 42 to the diameter D of the first door 2 in the vertical direction is 0.4 to 0.525.

[0156] In the vertical direction, if the ratio of the height H3 of the touch screen 42 to the diameter D of the first door 2 is too small, the display area will be too small and the display will be unclear. Therefore, within this range, the height H3 of the touch screen 42 is adjusted accordingly with its width to meet the display requirements and achieve efficient utilization of the front panel 11 space.

[0157] In some embodiments, combined with Figure 7 Along the horizontal direction, the width W3 of the touch screen 42 is greater than or equal to 10mm and less than the diameter D of the first door 2, which is 200mm to 380mm.

[0158] In some embodiments, the height H3 of the touch screen 42 is greater than or equal to 10 mm and less than the diameter D of the first door 2 in the vertical direction.

[0159] In this way, the display area can be clearly seen by the naked eye within a range of 1.5m, which can meet the display requirements and achieve efficient use of the space of the front panel 11. The height H3 of the touch screen 42 can be adjusted accordingly with its width.

[0160] In some embodiments, combined with Figure 6 , Figure 6 This is a schematic diagram of the structure of the touch screen 42 disposed on the top plate 12 according to an embodiment of this application. The control unit 4 includes the touch screen 42, and the housing 1 also includes the top plate 12, which is connected to the top of the front plate 11.

[0161] In some embodiments, the touch screen 42 is disposed on the top plate 12, and the ratio of the width W3 of the touch screen 42 to the width W4 of the top plate 12 along the first horizontal direction X is 0.432 to 0.567. The first horizontal direction X is the horizontal extension direction of the front plate 11.

[0162] Placing the touchscreen 42 on the top panel 12 brings its display area closer to the user's line of sight, allowing the user to easily view the screen by looking down, thus improving visibility. If the ratio of the width W3 of the touchscreen 42 to the width W4 of the top panel 12 is too small along the first horizontal direction X, the display area will be too small, resulting in unclear display. If the ratio is too large, the touchscreen 42 will extend beyond the edge of the top panel 12. Therefore, within this range, display requirements are met, achieving efficient utilization of the front panel 11 space.

[0163] In some embodiments, along the second horizontal direction Y, the ratio of the height H3 of the touch screen 42 to the height H4 of the top plate 12 is 0.072 to 0.095, and the second horizontal direction Y is perpendicular to the first horizontal direction X. The height H4 of the top plate 12 is the distance between two opposite edges of the top plate 12 along the second horizontal direction Y.

[0164] Along the second horizontal direction Y, if the ratio of the height H3 of the touchscreen 42 to the height H4 of the top panel 12 is too small, the display area will be too small, resulting in unclear display. If the ratio is too large, the display area of ​​the touchscreen 42 will be too large, leading to wasted space and cost. Therefore, within this range, the display requirements are met without excessively encroaching on the space of other components, achieving efficient utilization of the front panel 11 space.

[0165] In some embodiments, combined with Figure 6 Along the first horizontal direction X, the width W3 of the touch screen 42 is 50mm to 407mm.

[0166] Along the first horizontal direction X, when the width W3 of the touch screen 42 is less than 50mm, the display area is easily too small and the display is not clear. When the width W3 of the touch screen 42 is greater than 407mm, the touch screen 42 extends beyond the edge of the top plate 12.

[0167] For ease of explanation, the height H4 of the top plate 12 in all embodiments is 331mm. In some embodiments, the height H3 of the touch screen 42 along the second horizontal direction Y is 10mm to 150mm.

[0168] Along the second horizontal direction Y, when the height H3 of the touchscreen 42 is less than 10mm, the display area is easily too small, resulting in unclear display. When the height H3 of the touchscreen 42 is greater than 150mm, the display area of ​​the touchscreen 42 becomes too large, easily leading to wasted space and cost. Therefore, within this range, the display area is relatively clear to the naked eye within a 1.5m range, which satisfies the display requirements without excessively encroaching on the space of other components, achieving efficient utilization of the front panel 11 space.

[0169] In some embodiments, combined with Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the structure of the detergent storage box 5 movably connected to the front panel 11 as disclosed in the embodiments of this application. Figure 10 This is a schematic diagram of the structure of the detergent storage box 5 movably connected to the top plate 12 as disclosed in the embodiments of this application. The multi-drum washing machine also includes a detergent storage box 5, which is disposed inside the housing 1. The detergent storage box 5 has a accommodating space for accommodating detergent. The detergent storage box 5 is movably connected to the housing 1 so that the detergent storage box 5 can be pulled out of the housing 1 or stored inside the housing 1.

[0170] 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 5 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.

[0171] In some embodiments, combined with Figure 9 The detergent storage box 5 is movably connected to the front panel 11. The ratio of the height H5 of the detergent storage box 5 to the height H of the front panel 11 in the vertical direction is 0.12 to 0.158. The height H5 of the detergent storage box 5 is the distance between two opposite edges of the detergent storage box 5 in the vertical direction.

[0172] Because the soap dish has a limited depth, and the width of the detergent storage box 5 along the first horizontal direction X is constant, in the vertical direction, if the ratio of the height H5 of the detergent storage box 5 to the height H of the front panel 11 is too small, the volume of the detergent storage box 5 will be too small to hold enough detergent for the rated washing capacity of the machine. If the ratio of the height H5 of the detergent storage box 5 to the height H of the front panel 11 is too large, the height H5 of the detergent storage box 5 will be too large, resulting in an excessively large volume and wasting internal space of the casing 1. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be rationally utilized to avoid wasting space due to an excessively wide soap dish, allowing sufficient space inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0173] In some embodiments, along the first horizontal direction X, the ratio of the width W5 of the detergent storage box 5 to the width W of the front panel 11 is 0.32 to 0.42, and the first horizontal direction X is the horizontal extension direction of the front panel 11.

[0174] Because the soap dish has a limited depth, when the height H5 of the detergent storage box 5 is fixed, if the ratio of the width W5 of the detergent storage box 5 to the width W of the front panel 11 is too small, the volume of the detergent storage box 5 will be too small to hold enough detergent for the rated washing capacity of the machine. If the ratio of the width W5 of the detergent storage box 5 to the width W of the front panel 11 is too large, the height H5 of the detergent storage box 5 will be too large, resulting in an excessively large volume and wasting internal space of the casing 1. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be utilized rationally to avoid wasting space due to an excessively wide soap dish, allowing sufficient space inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0175] In some embodiments, the height H5 of the detergent storage box 5 in the vertical direction is 20mm to 150mm.

[0176] Because the soap dish has a limited depth, when the width of the detergent storage box 5 along the first horizontal direction X is fixed, if the height H5 of the detergent storage box 5 in the vertical direction is less than 20mm, the volume of the detergent storage box 5 is too small to hold enough detergent for the rated washing capacity of the machine. If the height H5 of the detergent storage box 5 is greater than 150mm, the height H5 of the detergent storage box 5 is too large, resulting in an excessively large volume and wasting internal space of the casing 1. Therefore, within this range, the internal space of the washing machine should be rationally utilized while ensuring sufficient detergent capacity, avoiding space waste caused by an excessively wide soap dish.

[0177] In some embodiments, the width W5 of the detergent storage box 5 along the first horizontal direction X is 50mm to 300mm.

[0178] Because the soap dish has a limited depth, when the height H5 of the detergent storage box 5 is fixed, along the first horizontal direction X, if the width W5 of the detergent storage box 5 is less than 50mm, the volume of the detergent storage box 5 is too small to hold enough detergent for the rated washing capacity of the machine. If the width W5 of the detergent storage box 5 is greater than 300mm, the width W5 is too large, resulting in an excessively large volume and wasting internal space in the casing 1. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be used rationally to avoid wasting space due to an excessively wide or high soap dish, allowing sufficient space inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0179] In some embodiments, the housing 1 further includes a top plate 12, which is connected to the top of the front plate 11.

[0180] In some embodiments, combined with Figure 10The detergent storage box 5 is movably connected to the top plate 12. Along the first horizontal direction X, the ratio of the width W5 of the detergent storage box 5 to the width W4 of the top plate 12 is 0.32 to 0.42. The first horizontal direction X is the horizontal extension direction of the front plate 11.

[0181] The detergent dispenser 5 is movably connected to the top plate 12, allowing users to easily bend down and open the lid to place detergent inside. Due to the limited depth of the soap dish, when the height of the detergent dispenser 5 along the second horizontal direction Y is constant, if the ratio of the width W5 of the detergent dispenser 5 to the width W4 of the top plate 12 along the first horizontal direction X is too small, the volume of the detergent dispenser 5 will be too small to hold enough detergent for the rated washing capacity of the machine. If the ratio is too large, the width W5 of the detergent dispenser 5 will be too large, resulting in an excessively large volume and wasting internal space in the casing 1. 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 inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0182] In some embodiments, along the second horizontal direction Y, the ratio of the height H5 of the detergent storage box 5 to the height H4 of the top plate 12 is 0.28 to 0.368, and the second horizontal direction Y is perpendicular to the first horizontal direction X.

[0183] Because the soap dish has a limited depth, when the width of the detergent storage box 5 along the first horizontal direction X is constant, if the ratio of the height H5 of the detergent storage box 5 to the height H4 of the top plate 12 along the second horizontal direction Y is too small, the volume of the detergent storage box 5 will be too small to hold enough detergent corresponding to the rated washing capacity of the machine. If the ratio of the height H5 of the detergent storage box 5 to the height H4 of the top plate 12 is too large, the height H5 of the detergent storage box 5 will be too large, resulting in an excessively large volume and wasting internal space of the casing 1. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be used rationally to avoid wasting space due to an excessively wide soap dish.

[0184] In some embodiments, the width W5 of the detergent storage box 5 along the first horizontal direction X is 50mm to 300mm.

[0185] Because the soap dish has a limited depth, when the height H5 of the detergent storage box 5 is fixed, along the first horizontal direction X, if the width W5 of the detergent storage box 5 is less than 50mm, the volume of the detergent storage box 5 is too small to hold enough detergent for the rated washing capacity of the machine. If the width W5 of the detergent storage box 5 is greater than 300mm, the width W5 is too large, resulting in an excessively large volume and wasting internal space in the casing 1. Therefore, within this range, while ensuring sufficient detergent capacity, the internal space of the washing machine should be utilized rationally to avoid wasting space due to an excessively wide soap dish, allowing sufficient space inside the washing machine for other components (such as the drum, drive assembly, etc.).

[0186] In some embodiments, the height H5 of the detergent storage box 5 along the second horizontal direction Y is 20mm to 300mm.

[0187] Because the soap dish has a limited depth, when the width of the detergent storage box 5 along the first horizontal direction X is fixed, if the height H5 of the detergent storage box 5 along the second horizontal direction Y is less than 20mm, the volume of the detergent storage box 5 is too small to hold enough detergent for the rated washing capacity of the machine. If the height H5 of the detergent storage box 5 is greater than 300mm, the height H5 of the detergent storage box 5 is too large, resulting in an excessively large volume and wasting internal space of the casing 1. Therefore, within this range, the internal space of the washing machine should be used rationally while ensuring sufficient detergent capacity, avoiding space waste caused by an excessively wide soap dish.
