[0029] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings denote the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present invention. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present invention, the scope of which is defined by the claims.

[0030] Exemplary implementations of the present invention provide a laundry treatment apparatus, which may be a double-cylinder washing machine, a double-cylinder dryer, a double-cylinder washer-dryer, or the like. As shown in FIGS. 1 to 19, the laundry treatment apparatus includes a cabinet 1, a first cylinder 2 and a second cylinder 3. Both the first cylinder 2 and the second cylinder 3 are disposed within the cabinet 1, and the second cylinder 3 is located at a side upper part of the first cylinder 2. A vibration damping structure 4 for the second cylinder 3 is disposed below the second cylinder 3.

[0031] The first cylinder 2 and the second cylinder 3 in the present invention may be, for example, outer cylinders of a washing machine. The cylinder structure of the washing machine generally includes an outer cylinder and an inner cylinder located inside the outer cylinder. Clothes to be washed are placed in the inner cylinder and complete washing under the drive of the rotation of the inner cylinder, while the outer cylinder remains fixed to support and fix the inner cylinder. The first cylinder 2 and the second cylinder 3 may have the same outer diameter or different outer diameters; for example, the outer diameter of the first cylinder 2 ranges from 500 mm to 575 mm, and the outer diameter of the second cylinder 3 ranges from 150 mm to 200 mm.

[0032] Different from a single-cylinder washing machine, a double-cylinder washing machine has a more complex structure due to the addition of one cylinder and a vibration damping structure equipped for the added cylinder. For the need of space avoidance and the like, a space is left between the first cylinder 2 and the second cylinder 3; however, due to the limited arrangement space, although a certain space is left below the second cylinder 3, the space is generally insufficient to arrange other components with a slightly larger volume. In addition, the vibration below the second cylinder 3 is mostly a small-range vibration. Considering the above technical problems, in the laundry treatment apparatus provided by the present invention, the vibration damping structure 4 is disposed below the second cylinder 3, which can fully utilize the limited space below the second cylinder 3 while meeting the vibration damping requirement of the second cylinder 3. It should be noted that "below the second cylinder 3" refers to below one side of a horizontal plane where a center of the cylinder opening or cylinder bottom of the second cylinder 3 is located; the center of the cylinder opening refers to an intersection point of a central axis of the cylinder body and a plane where the cylinder opening is located, for example, if the cylinder opening is a circle, the center of the cylinder opening is a corresponding circle center; the center of the cylinder bottom refers to an intersection point of the central axis of the cylinder and the cylinder bottom, for example, if the cylinder bottom is a circle, the center of the cylinder bottom is a corresponding circle center, or the center of the cylinder bottom may also be an intersection point of the cylinder bottom and a rotating shaft that drives the rotation of the cylinder body. "The vibration damping structure 4 of the second cylinder 3 is disposed below the second cylinder 3" refers to that the vibration damping structure 4 is at least partially located below the second cylinder 3, that is, the vibration damping structure 4 extends downward from the connection point with the second cylinder 3 or the cabinet 1 to the position below the second cylinder 3.

[0033] In some implementations, the vibration damping structure 4 is disposed only below the second cylinder 3; in other words, in some implementations, except that the vibration damping structure 4 is disposed below the second cylinder 3, no other structures are disposed at other positions of the second cylinder 3, which is beneficial to further save space. Alternatively, a balancing member to be introduced later or other devices different from the vibration damping structure 4 may also be disposed at other positions of the second cylinder 3, which will not be described in detail here.

[0034] The present invention is not intended to limit the specific form of the vibration damping structure 4; any structure that can be connected below the second cylinder 3 and can suppress the vibration of the second cylinder 3 can be applied in the present invention.

[0035] In some implementations, as shown in FIG. 3, the vibration damping structure 4 includes a first buffer member 41, and the first buffer member 41 is connected to the side wall of the cabinet 1, and / or the first buffer member 41 is connected to the bottom wall of the cabinet. The first buffer member 41 may be, for example, an elastic structure such as a compression spring, or a damping structure such as a damper. When the first buffer member 41 is a damper, it can not only provide a vibration damping effect but also play a role in supporting the second cylinder 3. For example, in the drawing, the first buffer member 41 is an obliquely arranged damper, and a housing section thereof is connected to the side wall or bottom wall of the cabinet 1, and a piston section thereof is connected to the second cylinder 3. In this implementation, the vibration damping structure 4 may only include the first buffer member 41, using a small number of components and has a simple structure, which is beneficial to save space. For the consideration of lightweight design, the side wall or the bottom wall of the cabinet 1 may not be designed too thick, so its strength is limited. In order to enhance the connection strength between the first buffer member 41 and the cabinet 1, optionally, a first reinforcing member 6 is disposed at a position of the side wall of the cabinet 1 corresponding to the first buffer member 41, and the first reinforcing member 6 may be, for example, a reinforced sheet metal. The sheet metal part has a relatively thin thickness, which can provide a reliable connection for the first buffer member 41, reduce the space occupation in the cabinet 1, and has a light weight.

[0036] In other implementations, as shown in FIG. 1, the vibration damping structure 4 includes a support beam 42 connected to the cabinet 1. The support beam 42 may play a role in supporting the second cylinder 3, and the vibration of the second cylinder 3 may be transmitted to the support beam 42, thereby sharing the vibration of the second cylinder 3. Further, as shown in FIG. 2, the vibration damping structure 4 further includes a second buffer member 43 disposed between the second cylinder 3 and the support beam 42. The second buffer member 43 may adopt a structure similar to that of the first buffer member 41, that is, the second buffer member 43 may also be an elastic structure such as a compression spring, or a damping structure such as a damper. In this implementation, by arranging the support beam 42 and the second buffer member 43 respectively, the second cylinder 3 can obtain a more reliable vibration damping effect. In addition, the support beam 42 can also play a role in supporting and fixing the second cylinder 3, and related components of the second cylinder 3, such as an air duct, may be fixed by means of the support beam 42.

[0037] The support beam 42 may be configured in a plate shape, a cylindrical shape, a rectangular strip shape, or the like according to actual conditions such as structural strength consideration or layout space optimization. An avoidance structure 423 may also be disposed on the support beam 42, and according to the different arrangement positions of the support beam 42, the avoidance structure 423 may be used to avoid the first cylinder 2, or avoid components between the first cylinder 2 and the bottom wall, or avoid components between the first cylinder 2 and the second cylinder 3.

[0038] As shown in FIG. 4, the laundry treatment apparatus may further include a balancing member 5. The balancing member 5 is connected between an upper part of the second cylinder 3 and the cabinet 1, and / or the balancing member 5 is connected between a side part of the second cylinder 3 and the cabinet 1, and / or the balancing member 5 is connected between the first cylinder 2 and the second cylinder 3. It should be noted that the balancing member 5 here is different from the aforementioned vibration damping structure 4; it plays a role in fixing and balancing the second cylinder 3, and when the vibration of the second cylinder 3 is too large, it can share part of the pressure on the vibration damping structure 4, so that the pressure does not all fall on the vibration damping structure 4, thereby prolonging the service life of the vibration damping structure 4. By taking a case where the vibration damping structure 4 is only disposed below the second cylinder 3 as an example, the balancing member 5 disposed above the second cylinder 3 is used to keep the second cylinder 3 balanced in an up-down direction when it vibrates; in this case, the balancing member 5 may be, for example, a hook disposed above the second cylinder 3. Alternatively, the balancing members 5 may also be disposed on the left and right sides of the second cylinder 3 to keep the second cylinder 3 balanced in a left-right direction when it vibrates; in this case, the balancing members 5 may be, for example, elastic baffles or the like. The balancing member 5 may be disposed at any suitable position in the cabinet 1 according to actual needs, such as avoiding the components of the cabinet 1.

[0039] In the implementations including the support beam 42, the support beam 42 may be configured into different structures according to actual needs. In some implementations, as shown in FIGS. 1 and 2, the support beam 42 may be connected only to one wall surface of the cabinet 1. That is, the support beam 42 does not extend to the other side walls but is in a suspended state. The wall surfaces here include not only the front, rear, left and right side walls but also the top wall and the bottom wall. In addition, the support beam 42 may be configured as an independent component or as a part of the wall surface. On the one hand, this structure of the support beam 42 can avoid the first cylinder 2 or other components by adjusting its extending length; on the other hand, compared with the structure of a through beam having both ends connected to the cabinet 1, it also can reduce the amount of materials used, and meet the requirement of lightweight design of the apparatus.

[0040] In the implementation where the support beam 42 is connected only to one side wall of the cabinet 1, the support beam 42 may be configured as a strip shape as shown in FIG. 1, with one end connected to the side wall of the cabinet 1 and the other end being a cantilever end; alternatively, the support beam 42 may also be configured as a U-shaped plate, with both ends connected to the side wall of the cabinet 1 and an arc segment forming a cantilever end.

[0041] In some implementations, as shown in FIGS. 1 and 2, one end of the support beam 42 is connected to one of the front side wall, the rear side wall, the left side wall or the right side wall of the cabinet 1, and the other end of the support beam 42 is the cantilever end. The cantilever end here refers to an end of the support beam 42 that does not extend to the other side walls and is in a suspended state. In other implementations, as shown in FIG. 13, the support beam 42 is configured as a U-shaped plate, both ends of the support beam 42 are connected to one of the front side wall, the rear side wall, the left side wall or the right side wall of the cabinet, and the arc segment of the support beam 42 is the cantilever end. It should be noted that dashed lines in the drawings are used to indicate the shielding relationship; that is, from the top view, part of the support beam 42 is shielded by the second cylinder 3, thus being shown as a dashed line. Dashed lines in other drawings are also used to indicate the shielding relationship, which will not be repeated here.

[0042] In some implementations, as shown in FIG. 5, one end of the support beam 42 is connected to the bottom wall of the cabinet 1, and the other end extends upward and is connected to the second cylinder 3. This manner is beneficial to be adopted when the lateral space is insufficient for arranging the support beam 42. Considering the limited design space in the cabinet 1, to reasonably optimize the layout of components and improve the flexibility of installation positions, as shown in FIG. 6, the avoidance structure 423 may be disposed on the support beam 42. The avoidance structure 423 may be used to avoid the cylinder or other components between the cylinder and the bottom wall. The avoidance structure 423 may be a stepped bend; in other implementations, the avoidance structure 423 may also be, for example, a recess at a position on the support beam 42 corresponding to the first cylinder 2, the present invention is not limited thereto. Further, as shown in FIG. 7, the second reinforcing member 7 may be disposed at a position on the bottom wall of the cabinet 1 corresponding to the support beam 42, and the second reinforcing member 7 may be, for example, a reinforced sheet metal.

[0043] The support beam 42 is configured to be simultaneously connected to at least two wall surfaces of the cabinet 1. That is, the support beam 42 is configured as a through beam connected to at least two wall surfaces of the cabinet 1.

[0044] In some implementations, both ends of the support beam 42 are respectively connected to the front side wall and the rear side wall of the cabinet 1, or both ends of the support beam are respectively connected to the left side wall and the right side wall of the cabinet 1. In some implementations, as shown in FIGS. 8 to 10, both ends of the support beam 42 respectively extend to the left side wall and the right side wall of the cabinet 1; in other implementations, the top view of FIG. 12 shows that both ends of the support beam 42 respectively extend to the front side wall and the rear side wall of the cabinet 1. Since both ends of such through beam are connected to the wall surfaces of the cabinet, the installation stability is better, which in turn can provide more reliable support for the second cylinder 3.

[0045] The support beam 42 may also be configured in a cross shape, a T shape, or an L shape. The cross-shaped support beam 42 may be simultaneously connected to four side walls. The T-shaped support beam 42 may be simultaneously connected to the left and right side walls and the front side wall, or may be simultaneously connected to the left and right side walls and the rear side wall, or may be simultaneously connected to the front and rear side walls and the left side wall, or may be simultaneously connected to the front and rear side walls and the right side wall. The L-shaped support beam 42 may be simultaneously connected to the left side wall and the front side wall, or may be simultaneously connected to the left side wall and the rear side wall, or may be simultaneously connected to the right side wall and the front side wall, or may be simultaneously connected to the right side wall and the rear side wall, or may be simultaneously connected to the top wall and one of the four side walls, or may be simultaneously connected to the bottom wall and one of the four side walls. In these implementations, the support beam 42 may be integrally formed or formed by splicing a plurality of beam bodies. In the scheme of splicing the plurality of beam bodies, there may be a splicing overlapped area, and since the strength of the overlapped area is high, the overlapped area may be located below the second cylinder 3. The front, rear, left, and right directions here refer to the front, rear, left, and right directions of a panel facing the user in a normal use state of the laundry treatment apparatus.

[0046] In some implementations, as shown in FIG. 14, the support beam 42 may be simultaneously connected to the front side wall, the rear side wall, the left side wall, and the right side wall of the cabinet 1. The support beam 42 may be, for example, a cross-shaped structure. This further improves the installation stability of the support beam 42 and the cabinet 1, and provides more reliable support for the second cylinder 3.

[0047] In still other implementations, as shown in FIG. 15, the support beam 42 is simultaneously connected to the left side wall, the right side wall and the front side wall of the cabinet 1, or the support beam 42 is simultaneously connected to the left side wall, the right side wall and the rear side wall of the cabinet 1, or the support beam 42 is simultaneously connected to the front side wall, the rear side wall and the left side wall of the cabinet 1, or the support beam is simultaneously connected to the front side wall, the rear side wall and the right side wall of the cabinet 1. The support beam 42 may be, for example, T-shaped. As shown, the support beam 42 is simultaneously connected to the front side wall, the rear side wall and the left side wall.

[0048] In some implementations, the support beam 42 is simultaneously connected to the left side wall and the front side wall of the cabinet 1, or the support beam 42 is simultaneously connected to the left side wall and the rear side wall of the cabinet 1, or the support beam 42 is simultaneously connected to the right side wall and the front side wall of the cabinet 1, or the support beam 42 is simultaneously connected to the right side wall and the rear side wall of the cabinet 1. FIG. 16 shows that the support beam 42 is simultaneously connected to the left side wall and the front side wall of the cabinet 1. Alternatively, in other implementations, one end of the support beam 42 is connected to one of the front side wall, the rear side wall, the left side wall or the right side wall of the cabinet 1, and the other end of the support beam 42 is connected to the top wall of the cabinet 1. Alternatively, one end of the support beam 42 is connected to one of the front side wall, the rear side wall, the left side wall or the right side wall of the cabinet 1, and the other end of the support beam 42 is connected to the bottom wall of the cabinet 1. The support beam 42 may be, for example, L-shaped. FIG. 11 shows that the support beam 42 is simultaneously connected to the left side wall and the bottom wall of the cabinet 1.

[0049] In addition, no matter that in the implementation where the support beam 42 is connected only to one wall surface of the cabinet 1 or in the implementation where the support beam 42 is connected to at least two wall surfaces of the cabinet 1, the second cylinder 3 may be directly connected to the support beam 42, or a second buffer member 43 may be further disposed between the second cylinder 3 and the support beam 42.

[0050] Considering that within the limited design space, the first cylinder 2 and the second cylinder 3 are relatively close to each other, for example, in the scheme where the support beam 42 is the through beam, in order to avoid interference with the first cylinder 2, as shown in FIGS. 9 and 10, the support beam 42 may be provided with an avoidance structure 423, and the avoidance structure 423 may be used to avoid the first cylinder 2 or avoid components between the first cylinder 2 and the second cylinder 3. The avoidance structure 423 as shown is a stepped bend. In other implementations, the avoidance structure 423 may also be, for example, a recess at a position on the support beam 42 corresponding to the first cylinder 2, and the present invention is not limited thereto. The vibration damping structure 4 of the second cylinder 3 is disposed below the second cylinder 3. In FIG. 9, the entire support beam 42 is located below the second cylinder 3; alternatively, as shown in FIG. 10, the positions where the two ends of the support beam 42 are connected to the side walls of the cabinet 1 are located at the side of the second cylinder 3 and bend downward to extend to the position below the second cylinder 3. Such bent beam body may be bendable according to the components that need to be avoided, and has higher flexibility.

[0051] As shown in FIG. 17, still taking the above structure where the support beam is configured as the through beam as an example, the support beam 42 includes a first beam segment 421 and a second beam segment 422. The second beam segment 422 is located below the second cylinder 3, and a width of the first beam segment 421 is smaller than that of the second beam segment 422. That is, the support beam 42 is configured such that its width tapers from a side close to the second cylinder 3 of the cabinet 1 to a side away from the second cylinder 3 of the cabinet 1. In this way, since the support beam 42 has a wider width at the position corresponding to the second cylinder 3, it can provide reliable support and vibration damping effects. The first beam segment 421, which may not be used for supporting or suspending the components, may be configured to be narrower than the second beam segment 422, thereby meeting the lightweight design requirement of the apparatus.

[0052] In addition, as shown in FIGS. 18 and 19, the support beam 42 includes a plurality of first beam bodies 424 arranged at intervals, or the support beam 42 includes one second beam body 425. Specifically, in the implementation shown in FIG. 19, the support beam 42 adopts one wider beam body, while in the implementation shown in FIG. 18, the support beam 42 adopts a plurality of narrower beam bodies arranged side by side, for example, two relatively narrow beam bodies may be used. The use of the plurality of narrower beam bodies is equivalent to a material reduction design for one wider beam body, which not only meets the vibration damping and support effects but also facilitate meeting the lightweight design requirement of the apparatus. In these implementations, although the illustration is given by taking the cantilever beam as an example, it should be understood that this structure can be applied to all the above-described schemes with the support beam 42, which will not be repeated here.

[0053] The technical solutions provided by the embodiments of the present invention may include following beneficial effects: in the laundry treatment apparatus provided by the present invention, the second cylinder is located at a side upper part of the first cylinder, and the vibration damping structure for the second cylinder is disposed below the second cylinder, for example, under consideration of some scenarios: after arranging the two cylinders, a space left below the second cylinder is generally insufficient to arrange other components, and the vibrations below the second cylinder are also mostly small-range vibrations. Therefore, in the laundry treatment apparatus provided by the present invention, the vibration damping structure is disposed below the second cylinder, which can fully utilize the limited space below the second cylinder while meeting the vibration damping requirement of the second cylinder.

[0054] After considering the specification and practicing the invention disclosed herein, those skilled in the art will be able to envisage other embodiments of the present invention. The present invention is intended to cover any variations, uses, or adaptive changes of the present invention, as defined by the claims.
