DETAILED EXECUTION FORMS

[0017] To clarify and make more understandable the objectives, technical solutions, and advantages of the present application, the present application is described in further detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein serve only to illustrate the present application and are not intended to limit it.

For example, different embodiments and technical solutions can be formed by combining various specific technical features. To avoid unnecessary repetition, the various possible combinations of the individual specific technical features are not explained separately in this application.

[0019] In the following description, the terms "first," "second," etc., are used solely to distinguish between different objects and do not indicate any similarities or connections between them. It should be understood that the directional terms "top," "bottom," "outside," and "inside" refer to the orientation in normal use, while the directional terms "left" and "right" denote the left-right direction shown in the corresponding schematic diagram, which may or may not correspond to the left-right direction of normal use.

[0020] It should be clarified that the terms "comprise," "contain," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a number of elements includes not only those elements but also other elements not expressly listed or elements inherent in that process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising a..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising that element. "Several" means two or more.

[0021] The embodiment of the present application provides a laundry treatment device 1.

[0022] It is understandable that the laundry treatment device 1 can include various forms, for example washing machine, spin dryer, dryer, washer-dryer combination, washer-dryer set, etc., whereby the laundry treatment device 1 can independently perform one or more functions such as washing, drying, spinning, etc.

[0023] Referring to Fig. 1 The laundry treatment device 1 comprises a carrier body 10, at least one first drum component 20, a first connecting element 40 and a second connecting element 50.

[0024] The carrier body 10 has an installation space 10a. The aforementioned at least one first drum component 20 is arranged in the installation space 10a.

[0025] It is understood that the support body 10 serves to provide a receiving space for the first drum component 20 and that the support body 10 has sufficient structural strength to act as a force-absorbing component, to bear vertical loads and to withstand horizontal actions, wherein the first drum component 20 is supported on the support body 10 and the support body 10 is able to bear at least the weight of the first drum component 20 and its load.

[0026] The first connecting element 40 is connected at one end to the first drum component 20 and at the other end to the support body 10. The second connecting element 50 is connected at one end to the first drum component 20 and at the other end to the support body 10.

[0027] It is understandable that both the first connecting element 40 and the second connecting element 50 are used to establish a force transmission relationship between the first drum component 20 and the support body 10, whereby at least a part of the weight of the first drum component 20 is transferred to the first connecting element 40 and / or the second connecting element 50, and the support body 10 bears at least a part of the weight of the first drum component 20 via the first connecting element 40 and / or the second connecting element 50.

[0028] The first connecting element 40 and the second connecting element 50 are arranged on opposite sides of the vertical midplane of the first drum component 20, the vertical midplane being a vertical plane passing through the axis of the first drum component 20 as shown in Fig. 3 with B shown. Thus, the combined action of the second connecting element 50 and the first connecting element 40 advantageously ensures that the first drum component 20 maintains a force equilibrium and exhibits good stability, thereby preventing the first drum component 20 from exhibiting a cantilever force state (if the first connecting element 40 and the second connecting element 50 are both located on the same side of the vertical mid-plane B, this force form can be understood as a cantilever force state, whereby this force distribution is unfavorable and leads to failure or damage of certain structures at the connection point).

[0029] With reference to Fig. 3 is the connection position of the first connecting element 40 with the support body 10, the first position 40a, the connection position of the second connecting element 50 with the support body 10 is the second position 50a, where the distance (hereinafter referred to as L2, see Fig. 3) between the first position 40a and the second position 50a in the left-right direction of the laundry treatment device 1 to the outer diameter D1 of the first drum component 20 there is a ratio of not less than 0.7, i.e. L2 / D1≥0.7, for example L2 / D1 is 0.7; 0.8; 0.84; 0.9 or 1.0 etc.

[0030] It should be explained that the left-right direction refers to the left and right sides of the laundry treatment device 1 in its normal operating condition, with the left-right direction running perpendicular to the vertical direction and the forward-backward direction of the laundry treatment device 1, i.e., the direction indicated by the arrow "left-right direction" in Fig. 1. Indicated direction.

[0031] In the laundry treatment device 1 of the embodiment of the present application, a force transmission and / or vibration transmission path to the support body 10 is established by the first drum component 20 by means of the first connecting element 40 and the second connecting element 50, wherein the first position 40a and the second position 50a function as two support points of the support body 10 for the first drum component 20, the ratio of the distance L2 between the first position 40a and the second position 50a in the left-right direction to the outer diameter D1 of the first drum component 20 is appropriately chosen, whereby the distance between the two support points of the first drum component 20 is relatively large and the force conditions of the first drum component 20 are improved and become more stable, which is analogous to the fact that a person standing with their feet spread apart is more stable than standing with their feet together.

[0032] In some embodiments, see Fig. 3, the ratio of the distance L2 between the first position 40a and the second position 50a in the left-right direction of the laundry treatment device 1 to the outer diameter D1 of the first drum component 20 is not greater than 1.4, that is, 1.4 ≥ L2 / D1, for example, L2 / D1 is 1.4; 1.3; 1.2; 1.1; 1.0; 0.9; 0.84; 0.8 or 0.7 etc.

[0033] It is understandable that by designing an appropriate distance between the first position 40a and the second position 50a in the left-right direction, both the space occupied by the first connecting element 40 and the second connecting element 50 in the left-right direction and the structural compactness of the laundry treatment device 1 are taken into account; Using the example of the first drum component 20, which is located in the upper right area of ​​the installation space, it is explained: If the distance between the first connecting element 40 and the second connecting element 50 in the left-right direction increases, this means that the second position 50a of the second connecting element 50 must be shifted to the left, thereby occupying the position to the left of the first drum component 20, so that the space provided for other components is very limited;Another scenario occurs when the first position 40a of the first connecting element 40 shifts to the right, causing the first drum component 20 to also move to the right. In this case, the safety distance between the first drum component 20 and the support body is very likely to be compromised. Therefore, this distance L2 takes into account both the space required and the reliability of the entire system. Furthermore, under eccentric loading of the first drum component 20, the difference in forces acting on the first connecting element 40 and the second connecting element 50 is advantageously reduced, thereby decreasing the failure risk of the first connecting element 40 and the second connecting element 50, thus ensuring the operational stability of the first drum component 20.

[0034] In some embodiments, the first connecting element 40 is rotatably connected to the support body 10 at its end furthest from the first drum component 20. This means that the first drum component 20 can rotate about the axis of the pivot point between the first connecting element 40 and the support body 10. It should be noted that the pivot point does not rotate at all times, but that vibrations can occur in certain situations, for example, when the laundry treatment machine 1 is running and the first drum component 20 generates vibrations, which can cause it to rotate about the axis of rotation.

[0035] The axis of rotation of the first connecting element 40 is referred to as the first axis (see Z in Fig. 2).

[0036] The first drum component 20 is rotatable about the first axis relative to the carrier body 10. It is understood that the first drum component 20 performs a rotary motion about the first axis. The inner drum of the first drum component 20 is rotatable about its own axis.

[0037] It is understandable that the first axis can be designed as a virtual straight line.

[0038] The elasticity of the second connecting element 50 is greater than the elasticity of the first connecting element 40.

[0039] It is to be explained that the elasticity of the second connecting element 50 is greater than the elasticity of the first connecting element 40, encompassing the following two cases: Firstly, the first connecting element 40 has almost no elasticity (can be understood as a mechanically rigid component); secondly, the first connecting element 40 may have some elasticity, but this elasticity is less than the elasticity of the second connecting element 50.

[0040] It is understandable that, during vibrations of the first drum component 20, the effective length of the second connecting element 50 can change due to its elasticity. This allows the second connecting element 50 and the first connecting element 40 to rotate the first drum component 20 around the axis of rotation of the first connecting element 40, thus dissipating vibrational energy. Furthermore, the first connecting element 40 is able to hold the first drum component 20 as a whole with a substantially fixed axis of rotation (i.e.,(the position of the first axis will not shift noticeably), wherein the first drum component 20 has virtually no displacement in the radial direction around the first axis as its center point, but rotates around the axis of rotation, so that the first drum component 20 and other structures in the aforementioned radial direction can maintain a relatively small safety distance, which is conducive to a compact structure.

[0041] In some embodiments, with reference to Fig. 3. The distance (hereinafter referred to as L21) from the first position 40a to the vertical midplane in the left-right direction is smaller than the distance (hereinafter referred to as L22) from the second position 50a to the vertical midplane in the left-right direction, i.e., L22 > L21. This causes the first drum component 20 to be positioned closer to the first position 40a overall, that is, the axis of the first drum component 20 is positioned closer to the first axis, thereby reducing the radius of rotation of the first drum component 20 about the first axis to further improve structural compactness.

[0042] In some embodiments, the first drum component 20 is suspended from the support body 10 by means of the second connecting element 50 and the first connecting element 40. It can also be understood that the first connecting element 40 absorbs tensile forces and the second connecting element 50 absorbs tensile forces. It is not necessary to arrange other structures below the first drum component 20 to support it, thus making the structure compact and creating more usable space in the area below the first drum component 20.

[0043] It should be explained that the specific structure of the second connecting element 50 is not limited and may, for example, comprise at least one damper or suspension spring (where the suspension spring is a form of the first elastic element). The damper may be a damper used in drum washing machines according to the prior art, which will not be discussed further here.

[0044] In some embodiments, see Fig. 2, the axis of rotation of the first connecting element 40 runs parallel to the axis of the first drum component 20. The first axis can essentially run parallel to the forward-backward direction of the laundry treatment device 1.

[0045] This means that the first drum component 20 can rotate around a horizontal axis, which makes the movement of the first drum component 20 more stable and allows the lateral vibration energy of the first drum component 20 to be absorbed better, thus increasing the damping effect and improving the overall stability of the laundry treatment device 1.

[0046] In some embodiments, the laundry treatment device 1 comprises a connecting shaft, wherein at least one of the carrier body 10 and the first connecting element 40 is formed with a shaft bore, wherein the connecting shaft is passed through the shaft bore to rotatably connect the first drum component 20 to the carrier body 10.

[0047] It is understood that at least one of the aforementioned first connecting element 40 and the support body 10 is provided with a shaft bore, wherein the connecting shaft is passed through the shaft bore, wherein the first connecting element 40 may be provided with a shaft bore, wherein one end of the connecting shaft is fixedly connected to the support body 10 and the other end is passed through the shaft bore of the first connecting element 40; It is also possible that the support body 10 is provided with a shaft bore, wherein one end of the connecting shaft is fixedly connected to the first connecting element 40 and the other end is passed through the shaft bore of the support body 10;It may further be provided that both the first connecting element 40 and the support body 10 are provided with shaft bores, wherein one end of the connecting shaft is passed through the shaft bore of the support body 10 and the other end is passed through the shaft bore of the first connecting element 40.

[0048] In some embodiments, see Fig. 1 and Fig. 3, the support body 10 comprises a deck support 11 and two first side supports 12, which are spaced apart from each other in the left-right direction of the laundry treatment device 1, wherein the deck support 11 is connected at its two opposite ends in the left-right direction to the two first side supports 12, and the deck support 11 and the two first side supports 12 enclose an installation space 10a.

[0049] For example, one of the first side supports 12 can be arranged to the left of the deck support 11, while the other first side support 12 is arranged to the right of the deck support 11.

[0050] Here, the deck support 11 and the two first side supports 12 exhibit a certain structural strength and form structures that can fulfill a load-bearing function.

[0051] For example, the first connecting element 40 is arranged closer to the first side support 12 relative to the second connecting element 50. For example, in the case of the upper left first drum component 20, of the first connecting element 40 and second connecting element 50 connected to the upper left first drum component 20, the first connecting element 40 is arranged closer to the first side support 12 on the left than the second connecting element 50. In the case of the upper right first drum component 20, of the first connecting element 40 and second connecting element 50 connected to the upper right first drum component 20, the first connecting element 40 is arranged closer to the first side support 12 on the right than the second connecting element 50.

[0052] In this embodiment, the first connecting element 40 is arranged relatively close to the edge of the support body 10 in the left-right direction, with the edge regions exhibiting higher structural strength and stiffness, reducing the vibration amplitude, and thus improving the stability of the laundry treatment device 1. Since the first connecting element 40 is arranged relatively close to the edge of the support body 10 in the left-right direction, the first axis is also located close to the edge of the support body 10 in the left-right direction, thereby optimally utilizing the space at the edge of the support body 10 in the left-right direction.

[0053] In some embodiments, the first connecting element 40 is connected with its end furthest from the first drum component 20 to the deck support 11 or the first side support 12 via a connecting shaft; and / or the second connecting element 50 is connected with its end furthest from the first drum component 20 to the deck support 11 or the first side support 12.

[0054] It should be explained that the foregoing can encompass the following several situations. First type: The first connecting element 40 is connected to the deck support 11 via a connecting shaft at its end furthest from the first drum component 20, and the second connecting element 50 is connected to the deck support 11 at its end furthest from the first drum component 20. Second type: The first connecting element 40 is connected to the deck support 11 via a connecting shaft at its end furthest from the first drum component 20, and the second connecting element 50 is connected to the first side support 12 at its end furthest from the first drum component 20.Third type: The first connecting element 40 is connected with its end furthest from the first drum component 20 via a connecting shaft to the first side support 12, and the second connecting element 50 is connected with its end furthest from the first drum component 20 to the deck support 11.

[0055] In some embodiments, with reference to Fig. 1, Fig. 2 to Fig. 3, the laundry treatment device 1 comprises a second drum component 30, wherein the second drum component 30 is arranged in the installation space 10a.

[0056] It is understandable that the first drum component 20 and the second drum component 30 can be used to perform the same laundry treatment function or to perform different laundry treatment functions. For example, in some embodiments, the first drum component 20 and the second drum component 30 can be used to wash or dry the same type of laundry or to wash or dry different types of laundry.For example, the first drum component 20 can be used for washing or drying underwear, socks, and similar items, while the second drum component 30 can be used for washing or drying outerwear and similar items. This allows for appropriate washing or drying processes depending on the size or washing or drying requirements of the laundry, thus increasing laundry treatment efficiency and reliability. In other embodiments, one of the first drum components 20 and the second drum component 30 are used for washing laundry, and the other for drying laundry, thereby providing multiple laundry treatment functions.

[0057] It should be explained that the first drum component 20 and the second drum component 30 can operate simultaneously or separately.

[0058] The first drum component 20 described above is located above the second drum component 30. "Above" here means that the axis position of the first drum component 20 is higher than the axis position of the second drum component 30, whereby the first drum component 20 can be located directly above, to the left above, to the right above, etc., the second drum component 30. This allows the laundry processing capacity to be increased without increasing the footprint, enabling independent operation of the first drum component 20 and the second drum component 30, or sequential operation to implement different functions.

[0059] In some embodiments, see Fig. In equation 3, the number of first drum components 20 is two, with the two first drum components 20 positioned to the left and above, and to the right and above, the second drum component 30. It is understandable that the two first drum components 20 are positioned to the left and above, and to the right and above, the second drum component 30, thus dividing the space above the second drum component 30 into a left upper space and a right upper space, with one first drum component 20 located in the left upper space and the other first drum component 20 in the right upper space. Since the space directly above the second drum component 30 is smaller relative to the left and right upper spaces, this arrangement allows for the avoidance of the space directly above the second drum component 30 and the full utilization of the left and right upper positions with respect to the second drum component 30.

[0060] The two aforementioned first drum components 20 can be used to perform the same laundry treatment function or to perform different laundry treatment functions. For example, in some embodiments, all first drum components 20 have the same laundry treatment function; for instance, they are all used for washing, or all for drying laundry, or each first drum component 20 combines both the washing and drying functions.

[0061] The two aforementioned first drum components 20 enable zoned washing of laundry. For example, one of the first drum components 20 can treat underwear and other close-fitting laundry, while the other first drum component 20 can treat socks and other laundry.

[0062] It should be explained that all first drum components 20 can operate simultaneously or separately. The volumes of all first drum components 20 can be the same or different; no restriction is imposed in this regard.

[0063] The aforementioned two first drum components 20 are arranged apart from each other in the left-right direction of the laundry treatment device 1, which advantageously reduces the space occupied by the aforementioned first drum components 20 in the vertical direction.

[0064] For example, the first two drum components 20 are not connected to each other, which reduces interference between the first drum components 20.

[0065] In some embodiments, the ratio of the shortest distance (hereinafter referred to as L1) between two adjacent first drum components 20 in the left-right direction to the dimension (hereinafter referred to as L) of the support body 10 in the left-right direction is 0.2~0.4, that is, 0.2≤L1 / L≤0.4, where, as an example for the dimension of the support body 10, the dimension of a standard housing is taken, if L is 600 mm (millimeters), then 240 mm≥L1≥120 mm, for example, L1 is 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 162 mm, 170 mm, 180 mm, 190 mm, 200 mm, 210 mm, 220 mm, 230 mm or 240 mm, etc.

[0066] It is understandable that the shortest distance between two adjacent first drum components 20 in the left-right direction can be appropriately designed, whereby more space can be created between or below the two first drum components 20, which can be used for installing components or for accommodating part of the second drum component 30, which helps to keep the dimensions of the laundry treatment device 1 as small as possible in the vertical direction.

[0067] Particularly in the case of a standard housing with a width of 590 mm to 610 mm, when accommodating two drum bodies and other components within the limited width range, the space between the opposing arc-shaped surfaces of the first drum components 20 can be fully utilized to arrange the remaining components by maintaining a specific distance between the two first drum components 20, thus making the structure more compact.

[0068] For example, the first drum component 20 has a first laundry treatment chamber 20a. The first laundry treatment chamber 20a is used to hold laundry.

[0069] In some embodiments, with reference to Fig. 3, the ratio of the outer diameter (hereinafter referred to as D1, see Fig. 3) The first drum component 20 has a dimension L of 0.23 to 0.28 in the left-right direction for the dimension L of the carrier body 10, that is, 0.23 ≤ D1 / L ≤ 0.28. Using the dimension of the carrier body 10 as an example of a standard housing dimension: for L = 600 mm, 168 mm ≥ D1 ≥ 138 mm, for example, D1 is 138 mm, 140 mm, 145 mm, 150 mm, 154 mm, 160 mm, 165 mm, or 168 mm, etc.

[0070] In this embodiment, it is made possible for the first laundry treatment chamber 20a of the first drum component 20 to have a relatively large volume, while at the same time a relatively small dimension in the left-right direction of the support body 10 is assumed, which is advantageous for maintaining an appropriate distance between two adjacent first drum components 20 in the left-right direction.

[0071] It should be explained that the aforementioned dimension L of the support body 10 in the left-right direction refers to the maximum distance between the two first side supports 12 in the left-right direction, that is, the distance from the left outer surface of the first side support 12 arranged on the left to the right outer surface of the first side support 12 arranged on the right.

[0072] In some embodiments, reference is made to Fig. 3 the ratio of the outer diameter D1 of the first drum component 20 to the dimension (hereinafter referred to as H, see Fig. 3) The height of the support body 10 is specified as 0.17~0.21, i.e., 0.17≤D1 / H≤0.21. If the dimension of the support body 10 is taken as the dimension of a standard housing, then for H = 800 mm: 168 mm≥D1≥136 mm, for example, D1 is: 136 mm, 138 mm, 140 mm, 145 mm, 150 mm, 154 mm, 160 mm, 165 mm or 168 mm, etc.

[0073] In this embodiment, it is ensured that the first laundry treatment chamber 20a of the first drum component 20 has a relatively large volume, while at the same time a relatively small dimension in the vertical direction of the support body 10 is taken into account, which leaves more space below the first drum component 20 that can be used to accommodate the second drum component 30 described below, which helps to ensure that the support body 10 maintains an appropriate dimension in the vertical direction.

[0074] It should be clarified that the aforementioned dimension H of the support body 10 in the vertical direction refers to the dimension of the first side support 12 in the vertical direction and does not include the height of the top support 11 and the base feet of the laundry treatment unit. For example, in a standard enclosure, the dimension H of the support body 10 in the vertical direction is 790 mm to 810 mm, while the height of the entire laundry treatment unit is 840 mm to 860 mm.

[0075] For example, the second drum component 30 has a second laundry treatment chamber 30a. The second laundry treatment chamber 30a serves to hold laundry.

[0076] For example, the outer diameter of the second drum component 30 is larger than the outer diameter of the first drum component 20. The capacity of the second laundry treatment chamber 30a is larger than the capacity of the first laundry treatment chamber 20a. The second drum component 30 can be referred to as the large drum, and the first drum component 20 can be referred to as the small drum.

[0077] Thus, the second drum component is able to handle 30 bulky washes or large quantities of laundry, for example outerwear, while the first drum component is able to handle 20 small-volume washes or small quantities of laundry, for example socks, underwear or baby clothes, etc.

[0078] In this embodiment, the volume of the second laundry treatment chamber 30a is larger than the volume of the first laundry treatment chamber 20a, with the weight of the second drum component 30 arranged below being higher, which advantageously lowers the overall center of gravity of the laundry treatment device 1 and increases the stability of the laundry treatment device 1. In some embodiments, with reference to Fig. 3, the ratio of the outer diameter (hereinafter referred to as D2, see Fig. 3) The dimension L of the second drum component 30 for the carrier body 10 in the left-right direction is specified as 0.82~1.0, that is, 0.82≤D2 / L≤1.0. Using the dimension of the carrier body 10 as a standard housing dimension as an example: if L is 600 mm, then 600 mm≥D2≥492 mm, for example, D2 is 492 mm, 500 mm, 510 mm, 520 mm, 530 mm, 540 mm, 542 mm, 550 mm, 556 mm, 560 mm, 570 mm, or 600 mm, etc.

[0079] In the relevant technology, single-drum washing machines with standard housing dimensions typically have an outer diameter of 450 mm to 550 mm.

[0080] In this embodiment, the second drum component 30 can fully utilize the space of the support body 10 in the left-right direction. Assuming the support body 10 has the same width in the left-right direction (for example, a standard housing width of 590 mm to 610 mm), the volume of the second drum component 30 becomes comparable to that of single-drum washing machines from the prior art. In this way, without reducing the volume of the large drum, at least two additional small drums can be added to improve the space utilization of the laundry treatment machine 1.

[0081] In some embodiments, see Fig. 3. The ratio of the outer diameter D2 of the second drum component 30 to the dimension H of the support body 10 in the vertical direction is 0.6~0.75, that is, 0.6≤D2 / H≤0.75. For the dimensions of the support body 10 as dimensions of a standard housing, for example: if H is 800 mm, then 600 mm≥D2≥480 mm, for example, D2 is 480 mm, 490 mm, 500 mm, 510 mm, 520 mm, 530 mm, 540 mm, 542 mm, 550 mm, 556 mm, 560 mm, or 600 mm, etc.

[0082] In this embodiment, the volume of the second drum component 30 corresponds to the volume of a single-drum washing machine of the prior art, wherein the second drum component 30 occupies an appropriate dimension in the vertical direction of the support body 10, thereby providing sufficient space for the installation of the upper first drum component 20, which is advantageous in order to keep the support body 10 in appropriate dimensions in the vertical direction.

[0083] In some embodiments, with reference to Fig. 3, the first drum component 20 and the second drum component 30 in projection onto a vertical plane parallel to the axis of the first drum component 20 (hereinafter referred to as B, see Fig. 3) an overlap area.

[0084] It is understandable that the vertical plane runs parallel to the height direction of the laundry treatment device 1, whereby the overlap area exhibited by the projections of the first drum component 20 and the second drum component 30 causes the dimension of the projections of the first drum component 20 and the second drum component 30 in the height direction to be smaller than the sum of the outer diameter of the first drum component 20 and the outer diameter of the second drum component 30. This favors a more compact structure and ensures that the dimension of the laundry treatment device 1 in the height direction is kept as small as possible.

[0085] In the embodiment with two first drum components 20, a part of the second drum component 30 is located in the space between the two first drum components 20. As a result, the projection of the part of the second drum component 30 located between the two first drum components 20 onto the vertical plane B overlaps with the projection of the first drum component 20 and forms the aforementioned overlap area.

[0086] In some embodiments, see Fig. 3 is the ratio of the dimension (hereinafter referred to as H1, see Fig. 3) of the overlap area in the vertical direction to the outer diameter D1 of the first drum component 20 0.1~0.4, i.e. 0.1≤H1 / D1≤0.4, for example H1 / D1 is 0.10; 0.11; 0.12; 0.123; 0.13; 0.14; 0.15; 0.20; 0.25; 0.30; 0.35 or 0.40 etc.

[0087] It is understandable that the ratio of dimension H1 of the overlap area in the vertical direction to the outer diameter D1 of the first drum component 20 is appropriate, thus ensuring a compact structure both vertically and horizontally. In particular, an adequate safety distance is maintained between the first drum component 20 and the second drum component 30 to prevent collisions between them during operation. If the aforementioned overlap area of ​​the first drum component 20 and the second drum component 30 exceeds 0.4, the first drum component 20 and the second drum component 30 would have to occupy a very large space horizontally, significantly increasing the dimensions of the support body 10 in this direction.

[0088] In some embodiments, as in Fig. Figure 3 shows the ratio of the dimension H1 of the overlap area in the vertical direction of the laundry treatment device 1 to the outer diameter (hereinafter referred to as D2, see Figure 3). Fig. 3) the second drum component 30 is set with 2%~4%, i.e. 2%≤H1 / D2≤5%, where H1 / D2 can be, for example, 2%, 2.2%, 2.4%, 2.6%, 2.8%, 3.0%, 3.5%, 3.7% or 4.0% etc.

[0089] It is understandable that under the comparison condition in which the outer diameter of the second drum component 30 corresponds to the outer diameter of the drum component of a conventional single-drum laundry treatment device 1, the ratio of the dimension H1 of the overlap area in the vertical direction to the outer diameter D2 of the second drum component 30 is expediently chosen in this embodiment, thereby achieving both effective use of space in the vertical direction and enabling a proper arrangement of the first drum component 20 without requiring a change in the dimension of the existing support body 10 in the horizontal direction.
