DETAILED DESCRIPTION

[0043] Hereinafter, a detailed description will be given of a specific embodiment of the disclosure with reference to the accompanying drawings. It should be understood that the specific embodiment described herein is merely intended to illustrate and explain the disclosure, and is not intended to limit the disclosure.

[0044] In the disclosure, it is to be understood that the positional words such as "upper, lower, front, rear" and the like used herein are defined with the drawing surface direction of the drawings, and are merely for the convenience of describing the disclosure and simplifying the description, and are not intended to indicate or imply that the indicated device or element must have a particular orientation, and a particular orientation configuration and operation, and thus should not be construed as limiting the disclosure. For example, upper, lower, front, rear are defined with the laundry treating apparatus in a normal use state, for example, the front side of the laundry treating apparatus can mean the side of the opening of the washing drum of the laundry treating apparatus, the rear side of the laundry treating apparatus means the side of the laundry treating apparatus close to the bottom of the washing drum, and "up-down direction" and "left-right direction" can be referred to as "front-rear direction" and "up-down direction" as shown in the drawings. Figure 1 and Figure 2

[0045] The terms "inner, outer" mean the inner and outer of the profile of the corresponding structure. In addition, it should be noted that the terms such as "first", "second" used herein are intended to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0046] In the description of the disclosure, it should be further noted that, unless explicitly specified and limited, the terms "provided", "connected", "linked", "mounted" should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the disclosure can be understood according to the specific circumstances.

[0047] ​In the related art, in order to save space, two drums in the cabinet are often rigidly connected together and share a set of damping equipment. On the one hand, this will cause the rigid connection structure part of the drum to bear a large shear and bending load during the operation of the drum, which is easy to cause the laundry washing equipment to fail and reduce the service life of the washing machine. On the other hand, when the two drums are rigidly connected together, the independent operation of one small drum will seriously interfere with the motion state of the other drum, which destroys the effect of separate washing of the two drums.

[0048] In view of this, as shown in the Figures 1 to 4 The laundry washing equipment 100 provided by the present disclosure includes a cabinet 1, a first drum 2, a second drum 3, a third drum 8, and a flexible structure 5. The first drum 2, the second drum 3, and the third drum 8 are all arranged in a cavity 11 in the cabinet 1 and are connected to the cabinet 1. The first drum 2 and the second drum 3 are connected through the flexible structure 5.

[0049] Here, it should be noted that the flexible structure 5 mentioned above refers to a structure that can deform or stretch under the action of an external force. For example, the flexible structure 5 can be an elastic member 53 mentioned below, or it can be a damping rod mentioned below, and the present disclosure does not limit this.

[0050] In the laundry washing equipment 100 described above, since the first drum 2, the second drum 3, and the third drum 8 are all connected to the cabinet 1, the first drum 2, the second drum 3, and the third drum 8 have good fixing effect on the cabinet 1. During use, the first drum 2, the second drum 3, and the third drum 8 will not produce large displacement in the cabinet 1, and the vibration and noise of the laundry washing equipment 100 are small, which is beneficial to improve the working efficiency and service life of the laundry washing equipment 100.

[0051] Through the above technical solution, since the laundry washing equipment 100 includes the first drum 2, the second drum 3, and the third drum 8, and the first drum 2, the second drum 3, and the third drum 8 are all arranged in the space in the cabinet 1, by reasonably designing the functions of the three drums, the laundry washing equipment 100 can realize the functions of single-machine partition washing and / or washing and drying integration. Only one laundry washing equipment 100 can meet the user's demand for separate washing of different clothes (such as adult clothes, baby clothes, and underwear, etc.), and the practicality of the laundry washing equipment 100 is high.

[0052] And, since the first drum 2 and the second drum 3 are connected through the flexible structure 5, in this way, it is allowed to not separately provide two sets of damping devices for the first drum 2 and the second drum 3, and the fixing of the first drum 2 and the second drum 3 in the cabinet 1 can be realized through the flexible structure 5 and the connecting structure provided on both sides of the first drum 2 and the second drum 3. In this way, on the one hand, it is conducive to simplifying the structure of the whole laundry washing apparatus 100, reducing the space occupation caused by the use of two sets of damping devices, so as to facilitate the arrangement of other parts in the laundry washing apparatus 100 in the cabinet 1, and the compactness of the laundry washing apparatus 100 is higher; on the other hand, it can also reduce the cost increase caused by the use of the above two sets of damping devices, and the production and manufacturing cost of the laundry washing apparatus 100 is lower.

[0053] In addition, since the first drum 2 and the second drum 3 are connected through the flexible structure 5, in this way, on the one hand, when the first drum 2 and / or the second drum 3 vibrate during operation, the flexible structure 5 can deform or stretch under the action of external force, thereby effectively absorbing the energy of vibration, which makes the stress concentration of the flexible structure 5 smaller, can withstand larger shear and bending load, and reduces the risk of damage of the flexible structure 5; on the other hand, during the operation of the first drum 2 and the second drum 3, the flexible structure 5 can also absorb vibration energy by deformation or stretching, reducing the transmission of vibration from one to the other, which is conducive to reducing the mutual interference between the first drum 2 and the second drum 3, thereby improving the washing effect of the first drum 2 and the second drum 3.

[0054] Here, it needs to be explained that the specific functions of the above-mentioned first drum 2, second drum 3 and third drum 8 are not limited in the present disclosure, and in the present disclosure, the first drum 2, second drum 3 and third drum 8 can be any one of a drying drum, a washing drum and a washing-drying drum.

[0055] For example, when the first drum 2 is a washing drum, the first drum 2 can have a washing function, so that the first drum 2 can wash the laundry in the first drum 2.

[0056] When the first drum 2 is a washing-drying drum, the first drum 2 can have both washing function and drying function, so that the first drum 2 can wash and dry the laundry in the first drum 2.

[0057] Similarly, when the second drum 3 is a washing drum, the second drum 3 can have a washing function, so that the second drum 3 can wash the laundry in the second drum 3.

[0058] When the second drum 3 is a washing-drying drum, the second drum 3 can have both washing function and drying function, so that the second drum 3 can wash and dry the laundry in the second drum 3.

[0059] In addition, when the third drum 8 is a washing drum, the third drum 8 can have a washing function, so that the third drum 8 can wash the laundry in the third drum 8.

[0060] When the third drum 8 is a washing and drying drum, the third drum 8 can have both washing and drying functions, so that the third drum 8 can wash and dry the laundry in the third drum 8.

[0061] Through the function combination of the first drum 2, the second drum 3 and the third drum 8, the above-mentioned laundry washing apparatus 100 can have the functions of separate washing (e.g., one drum for washing outerwear, one drum for washing baby clothes, and another drum for washing underwear and other close-fitting clothes), separate drying or washing and drying integration.

[0062] In the present disclosure, the first drum 2 and the second drum 3 can have any appropriate arrangement in the cabinet 1, for example, the first drum 2 and the second drum 3 can be arranged in the cabinet 1 in the up-down direction, or the first drum 2 and the second drum 3 can be arranged in the cabinet 1 in the left-right direction, which is not limited in the present disclosure. As an embodiment of the present disclosure, the above-mentioned first drum 2 and the second drum 3 are arranged in the left-right direction of the cabinet 1, and the flexible structure 5 is arranged between the first drum 2 and the second drum 3.

[0063] In this way, by reasonably designing the arrangement positions of the first drum 2 and the second drum 3 in the cabinet 1, the third drum 3 can be arranged in the cabinet 1, so that the single-machine partition washing and / or washing and drying integration function of the laundry washing apparatus 100 can be realized.

[0064] Alternatively, as shown in Figure 1 and Figure 2 , the first drum 2 and the second drum 3 are arranged symmetrically about the center plane in the left-right direction of the cabinet 1. The first drum 2 and the second drum 3 arranged symmetrically in the left-right direction of the cabinet 1 can on the one hand improve the weight balance of the laundry washing apparatus 100, and the laundry washing apparatus 100 with higher balance has less vibration and noise during use; on the other hand, the first drum 2 and the second drum 3 arranged symmetrically have higher aesthetics, which is conducive to improving the user experience.

[0065] Here, it should be noted that for the embodiment in which the first drum 2 and the second drum 3 are arranged in the left-right direction of the cabinet 1, the present disclosure does not limit the specific connection mode between the first drum 2 and the second drum 3 and the cabinet 1, as long as the first drum 2 and the second drum 3 can be reliably connected to the cabinet 1, so as to meet the use requirements of the laundry washing apparatus 100. As an embodiment of the present disclosure, as shown in Figure 1 and Figure 2As shown, the aforementioned laundry washing equipment 100 also includes a first vibration damping structure 60 and a second vibration damping structure 70. The side of the first drum 2 opposite to the flexible structure 5 is connected to the housing 1 via the first vibration damping structure 60, and the side of the second drum 3 opposite to the flexible structure 5 is connected to the housing 1 via the second vibration damping structure 70. In other words, the side of the first drum 2 away from the flexible structure 5 and the side of the second drum 3 away from the flexible structure 5 are respectively connected to the housing 1 via the first vibration damping structure 60 and the second vibration damping structure 70. The first vibration damping structure 60 and the second vibration damping structure 70 can cooperate with the flexible structure 5 to fix the first drum 2 and the second drum 3 inside the housing. The fixation effect of the first drum 2 and the second drum 3 inside the housing 1 is good, and there will be no large shaking.

[0066] Furthermore, since the first damping structure 60 and the flexible structure 5 are respectively provided on both sides of the first cylinder 2, on the one hand, the force exerted on the first cylinder 2 by the first damping structure 60 and the flexible structure 5 connected to both sides of the first cylinder 2 is relatively uniform, which is conducive to improving the balance of the first cylinder 2 during use; on the other hand, the first damping structure 60 and the flexible structure 5 connected to both sides of the first cylinder 2 can both play a role in damping the vibration of the first cylinder 2, thereby helping to reduce the vibration and noise generated by the first cylinder 2 during use and improving the user experience.

[0067] Furthermore, since the second vibration damping structure 70 and the flexible structure 5 are respectively provided on both sides of the second cylinder 3, on the one hand, the force exerted on the second cylinder 3 by the second vibration damping structure 70 and the flexible structure 5 connected to both sides of the second cylinder 3 is more uniform, which is conducive to improving the balance of the second cylinder 3 during use; on the other hand, the second vibration damping structure 70 and the flexible structure 5 connected to both sides of the second cylinder 3 can both play a role in damping the vibration of the second cylinder 3, thereby helping to reduce the vibration and noise generated by the second cylinder 3 during use and improving the user experience.

[0068] It should be noted that this disclosure does not limit the specific configuration of the first vibration damping structure 60. As one embodiment of this disclosure, such as... Figure 1 As shown, the first vibration damping structure 60 includes a first suspension spring 6 and a first damping support rod 7 arranged along the vertical direction of the housing 1, and the first cylinder 2 is connected to the housing 1 through the first suspension spring 6 and the first damping support rod 7.

[0069] The first suspension spring 6 and the first damping support rod 7 can absorb and dissipate the energy of vibration generated by the first drum 2 during use, thereby reducing the vibration generated by the first drum 2 when it is running at high speed, which is beneficial to improving the stability of the laundry washing equipment 100 and reducing the noise during the operation of the laundry washing equipment 100.

[0070] For the embodiment in which the first damping structure 60 comprises the first suspension spring 6 and the first damping support rod 7, optionally, as shown in Figure 1 and Figure 2 indicated, along the up-down direction of the cabinet 1, the height of the flexible structure 5 is higher than the height of the first damping support rod 7, and the height of the flexible structure 5 is lower than the height of the first suspension spring 6. In other words, along the up-down direction of the cabinet 1, the flexible structure 5 is arranged between the first suspension spring 6 and the first damping support rod 7, thus, by reasonably designing the connection position of the flexible structure 5 and the first cylinder 2, the first suspension spring 6, the first damping support rod 7 and the flexible structure 5 can form multi-point (such as three-point) support for the first cylinder 2, further improving the fixing effect of the first cylinder 2 in the cabinet 1.

[0071] The specific structure of the second damping structure 70 is not limited in the present disclosure, and as an embodiment of the present disclosure, as shown in Figure 1 , the second damping structure 70 comprises a second suspension spring 9 and a second damping support rod 10 arranged along the up-down direction of the cabinet 1, and the second cylinder 3 is connected to the cabinet 1 through the second suspension spring 9 and the second damping support rod 10.

[0072] The second suspension spring 9 and the second damping support rod 10 can absorb and dissipate the energy of the vibration generated by the second cylinder 3 during use, thereby reducing the vibration generated by the second cylinder 3 during high-speed operation, which is beneficial to improve the stability of the laundry washing apparatus 100 and reduce the noise during operation of the laundry washing apparatus 100.

[0073] For the embodiment in which the second damping structure 70 comprises the second suspension spring 9 and the second damping support rod 10, optionally, as shown in Figure 1 and Figure 2 indicated, along the up-down direction of the cabinet 1, the height of the flexible structure 5 is higher than the height of the second damping support rod 10, and the height of the flexible structure 5 is lower than the height of the second suspension spring 9. In other words, along the up-down direction of the cabinet 1, the flexible structure 5 is arranged between the second suspension spring 9 and the first damping support rod 7, thus, by reasonably designing the connection position of the flexible structure 5 and the second cylinder 3, the first suspension spring 6, the first damping support rod 7 and the flexible structure 5 can form multi-point (such as three-point) support for the second cylinder 3, further improving the fixing effect of the second cylinder 3 in the cabinet 1.

[0074] In order to improve the connection effect between the first cylinder 2 and the second cylinder 3, optionally, as shown in Figure 1 and Figure 2As shown, the first cylinder 2 and the second cylinder 3 are arranged in the left-right direction of the cabinet 1, and the flexible structure 5 comprises a plurality of flexible members 51, which are arranged in the first cylinder 2 and the second cylinder 3 in the left-right direction of the cabinet 1, and one end of each flexible member 51 is connected to the first cylinder 2, and the other end of each flexible member 51 is connected to the second cylinder 3. In other words, the first cylinder 2 and the second cylinder 3 are connected by the plurality of flexible members 51.

[0075] In this way, first, the plurality of flexible members 51 can fix the first cylinder 2 and the second cylinder 3, which is conducive to improving the fixing effect of the first cylinder 2 and the second cylinder 3 in the cabinet 1; second, the plurality of flexible members 51 can absorb the vibration energy, thereby further reducing the mutual interference between the first cylinder 2 and the second cylinder 3; third, the plurality of flexible members 51 can jointly bear the force generated when the first cylinder 2 and the second cylinder 3 vibrate, and each flexible member 51 bears a smaller force, and the flexible member 51 bearing a smaller force is less likely to be damaged and has a longer service life.

[0076] Here, it should be noted that for the embodiment in which the flexible structure 5 comprises a plurality of flexible members 51, the present disclosure does not limit the arrangement of the plurality of flexible members 51 in the cabinet 1, for example, the plurality of flexible members 51 can be arranged in the front-rear direction (the width direction of the cabinet 1) of the cabinet 1 between the first cylinder 2 and the second cylinder 3, and the plurality of flexible members 51 can be arranged in the up-down direction (the height direction of the cabinet 1) of the cabinet 1 between the first cylinder 2 and the second cylinder 3, and the present disclosure does not limit this.

[0077] As an embodiment of the present disclosure, as shown in Figure 1 and Figure 2 The plurality of flexible members 51 comprise at least two flexible members 51 arranged in the up-down direction of the cabinet 1. The flexible members 51 arranged in the up-down direction of the cabinet 1 can be connected to different positions of the first cylinder 2 and the second cylinder 3, so that, on the one hand, the connection between the first cylinder 2 and the second cylinder 3 connected by the plurality of different positions is reliable and less likely to shake, and the stability of the first cylinder 2 and the second cylinder 3 is higher; on the other hand, the flexible members 51 connected at different positions can absorb the vibration energy of different positions of the first cylinder 2 and the second cylinder 3, thereby further reducing the mutual interference between the first cylinder 2 and the second cylinder 3, and the washing effect of the first cylinder 2 and the second cylinder is better.

[0078] Optionally, as shown in Figure 1 and Figure 2As shown, the first cylinder 2 and the second cylinder 3 both extend along the front-rear direction of the cabinet 1, and the plurality of flexible members 51 includes at least two flexible members 51 arranged staggered in the front-rear direction of the cabinet 1. Since the plurality of flexible members 51 includes at least two flexible members 51 arranged staggered in the front-rear direction of the cabinet 1, the flexible structure 5 can realize the connection of the first cylinder 2 and the second cylinder 3 at different positions in the front-rear direction, so as to improve the reliability of the connection of the first cylinder 2 and the second cylinder 3 and the damping effect in the front-rear direction.

[0079] It should be noted that the specific type of the flexible structure 5 is not limited in the present disclosure, as long as the flexible structure 5 is suitable to be arranged between the first cylinder 2 and the second cylinder 3. As an embodiment of the present disclosure, as shown in Figures 1 to 4 The flexible structure 5 includes at least one flexible member 51, and the flexible member 51 can include an elastic member 53, both ends of the elastic member 53 being connected to the first cylinder 2 and the second cylinder 3 respectively. The elastic member 53 can be deformed under the vibration of the first cylinder 2 and the second cylinder 3, so as to absorb the vibration energy of the first cylinder 2 and the second cylinder 3, the elastic member 53 being not easy to be damaged, and the mutual interference between the first cylinder 2 and the second cylinder 3 can be reduced.

[0080] Optionally, as shown in Figures 1 to 4 The elastic member 53 can be a spring, one end of the spring being connected to the first cylinder 2, and the other end of the spring being connected to the second cylinder 3.

[0081] As another embodiment of the present disclosure, the flexible member 51 of the flexible structure 5 can include a damping rod, both ends of the damping rod being connected to the first cylinder 2 and the second cylinder 3 respectively. The damping rod can be stretched and contracted under the vibration of the first cylinder 2 and the second cylinder 3, so as to absorb the vibration energy of the first cylinder 2 and the second cylinder 3, the damping member being not easy to be damaged, and the mutual interference between the first cylinder 2 and the second cylinder 3 can be reduced.

[0082] Optionally, when the flexible structure 5 includes a plurality of flexible members 51, all of the plurality of flexible members 51 can be elastic members, or all of the plurality of flexible members 51 can be damping rods, or the plurality of flexible members 51 can include part elastic members and part damping rods.

[0083] In order to facilitate the connection of the flexible structure 5 with the first cylinder 2 and the second cylinder 3, optionally, as shown in Figure 3 The first cylinder 2 and the second cylinder 3 are both provided with a connecting portion 4, and the connecting portion 4 is used to be detachably connected with the flexible structure 5. In this way, only by connecting both ends of the flexible structure 5 with the connecting portions 4 on the first cylinder 2 and the second cylinder 3 respectively, the connection between the flexible structure 5 and the first cylinder 2 and the second cylinder 3 can be realized, and the connection between the flexible structure 5 and the first cylinder 2 and the second cylinder 3 is relatively convenient.

[0084] In addition, since the connecting portion 4 is detachably connected with the flexible structure 5, if one or more of the flexible structure 5, the first drum 2 and the second drum 3 is damaged during use, the laundry washing appliance 100 can be repaired by replacing only the damaged part, which is beneficial to reduce the use cost of the laundry washing appliance 100.

[0085] As other embodiments of the present disclosure, the flexible structure 5 can also be bonded or welded on the first drum 2 and the second drum 3, which is not limited in the present disclosure.

[0086] It should be noted that the present disclosure does not limit the specific structure of the connecting portion 4 described above, as long as the connecting portion 4 is convenient to connect with the flexible structure 5. As an embodiment of the present disclosure, as shown in Figure 3 and Figure 4 The connecting portion 4 can include a lug 41 with a connecting hole 42 formed therein, and the flexible structure 5 can be provided with a hook portion 52 which is hooked on the connecting hole 42.

[0087] In this way, by hooking or unhooking the hook portion 52 on the flexible structure 5 on the connecting hole 42 on the lug 41, the connection between the flexible structure 5 and the first drum 2 or the second drum 3 can be achieved, and the flexible structure 5 can be conveniently disassembled on the first drum 2 and the second drum 3.

[0088] Here, it can be understood that for the embodiment in which the flexible structure 5 is configured as a spring, the hook portion 52 can be provided at both ends of the spring and used to connect with the connecting portion 4.

[0089] As other embodiments of the present disclosure, the connecting portion 4 can also include a connecting hole on the first drum 2 and the second drum 3 and a stop flange in the connecting hole, and the flexible structure 5 can also be provided with a clamping leg which can be partially inserted into the connecting hole and limited in the connecting hole by the stop flange. In this way, the detachable connection between the flexible structure 5 and the connecting portion 4 can also be achieved.

[0090] In order to further reduce the mutual interference between the first drum 2 and the second drum 3 when the laundry washing appliance 100 is running, optionally, the connecting portion 4 on the first drum 2 is rotatably connected to the first drum 2 about an axis extending in the up-down direction of the cabinet 1, and / or the connecting portion 4 on the second drum 3 is rotatably connected to the second drum 3 about an axis extending in the up-down direction of the cabinet 1, i.e., only the connecting portion 4 on the first drum 2 can be rotatably connected to the first drum 2 about an axis which can extend in the up-down direction of the cabinet 1,

[0091] Alternatively, the connecting portion 4 on the second drum 3 can be rotatably connected to the second drum 3 about an axis extending in the up-down direction of the cabinet 1, or the connecting portion 4 on the first drum 2 can be rotatably connected to the first drum 2 about an axis extending in the up-down direction of the cabinet 1, and the connecting portion 4 on the second drum 3 can be rotatably connected to the second drum 3 about an axis extending in the up-down direction of the cabinet 1.

[0092] In this way, during use, if the first drum 2 and / or the second drum 3 vibrate, the first drum 2 and the second drum 3 can move in the extension direction of the flexible structure 5 and in the front-rear direction of the cabinet 1, and the flexible structure 5 can deform or stretch in multiple directions under the vibration of the first drum 2 and / or the second drum 3, thereby absorbing the vibration energy of the first drum 2 and the second drum 3 in multiple directions, further reducing the stress concentration of the flexible structure 5, and further reducing the mutual interference between the first drum 2 and the second drum 3.

[0093] Here, it should be noted that the present disclosure does not limit the mounting manner of the third drum 8 in the cabinet 1, as long as the third drum 8 can be reliably mounted in the cabinet 1 and is not prone to shaking. As an embodiment of the present disclosure, as shown in Figure 1 The laundry washing appliance 100 can also comprise two third suspension springs 20 and two third damping support rods 30, the upper portion of the third drum 8 being connected to the cabinet 1 by means of the two third suspension springs 20, and the lower portion of the third drum 8 being connected to the cabinet 1 by means of the two third damping support rods 30. The third drum 8 connected to the cabinet 1 by means of the plurality of connecting members (i.e. the third suspension springs 20 and the third damping support rods 30) is reliably fixed in the cabinet 1 and is not prone to large displacement, and the laundry washing appliance 100 has less vibration and noise.

[0094] Here, it should be noted that the present disclosure does not limit the specific arrangement positions of the first drum 2, the second drum 3 and the third drum 8 in the cabinet 1, as long as the first drum 2, the second drum 3 and the third drum 8 can meet the use requirements of the laundry washing appliance 100. As an embodiment of the present disclosure, as shown in Figure 1 The first drum 2 and the second drum 3 are arranged at the upper portion of the cavity 11, and the third drum 8 is arranged below the first drum 2 and below the second drum 3. In this way, by reasonably designing the relative positions of the first drum 2, the second drum 3 and the third drum 8, on the one hand, the first drum 2, the second drum 3 and the third drum 8 can be prevented from interfering with each other, and on the other hand, the user can conveniently take the laundry.

[0095] The present disclosure does not limit the relative positional relationship between the first drum 2, the second drum 3 and the third drum 8. As an embodiment of the present disclosure, as shown in Figure 1As shown, the height of the bottom of the first tub 2 is higher than the height of the top of the third tub 8, and / or the height of the bottom of the second tub 3 is higher than the height of the top of the third tub 8.

[0096] Wherein, optionally, the bottom of the first tub 2 and the second tub 3 can be the outer bottom surface of the outer tub of the first tub 2 and the second tub 3. The top of the third tub 8 can be the outer top surface of the outer tub of the third tub 8 (i.e. the outer top surface of the side of the outer tub of the third tub 8 away from the bottom of the cabinet 1), which is not limited in the present disclosure.

[0097] Since the height of the top of the third tub 8 is lower than the height of the bottom of the first tub 2 and the second tub 3, by reasonably designing the arrangement positions of the first tub 2, the second tub 3 and the third tub 8 in the cabinet 1, the first tub 2 and the second tub 3 can have a longer dimension in the vertical direction, and the longer-dimension first tub 2 and the second tub 3 can have a larger volume, so that the first tub 2 and the second tub 3 can accommodate a certain volume of laundry to meet the washing requirements of the first tub 2 and the second tub 3, and improve the washing ratio.

[0098] As another embodiment of the present disclosure, the height of the bottom of the first tub 2 and the second tub 3 can also be higher than the height of the top of the third tub 8.

[0099] Since the height of the top of the third tub 8 is lower than the height of the bottom of the first tub 2 and the second tub 3, by reasonably designing the arrangement positions of the first tub 2, the second tub 3 and the third tub 8 in the cabinet 1, the first tub 2 and the second tub 3 can have a longer dimension in the vertical direction, and the longer-dimension first tub 2 and the second tub 3 can have a larger volume, so that the first tub 2 and the second tub 3 can accommodate a certain volume of laundry to meet the washing requirements of the first tub 2 and the second tub 3, and improve the washing ratio.

[0100] In addition, by staggered arrangement of the first tub 2, the second tub 3 and the third tub 8, the space occupation of the first tub 2, the second tub 3 and the third tub 8 in the up-down direction of the cabinet 1 can be reduced, which is beneficial to reduce the height of the cabinet 1, so that the laundry washing apparatus 100 can be conveniently arranged in the user's home, while the washing volume and the clothes taking can also be taken into account.

[0101] It should be noted that the present disclosure does not limit the size of the first tub 2, the second tub 3 and the third tub 8, and the first tub 2, the second tub 3 and the third tub 8 can have any appropriate size as long as they can meet the washing requirements of the laundry washing apparatus 100. As an embodiment of the present disclosure, as shown in Figure 1As shown, the diameter of the third drum 8 is larger than the diameter of the first drum 2 and the diameter of the second drum 3. The third drum 8 with larger diameter can have larger volume, so that the third drum 8 can accommodate more laundry, meeting the requirement of single-time mass washing or drying of the user.

[0102] In addition, the first drum 2 and the second drum 3 with smaller diameter can reduce the size of the first drum 2 and the second drum 3, so as to reduce the height of the cabinet 1, facilitating the arrangement of the laundry washing apparatus 100 in the user's home.

[0103] Optionally, as shown, Figure 1 As shown, the center of the third drum 8 in the left-right direction of the cabinet 1 is located at the center of the left-right direction of the cabinet 1. Arranging the third drum 8 in this way is conducive to improving the weight balance of the laundry washing apparatus 100, thereby facilitating the reduction of vibration and noise of the laundry washing apparatus 100 during use.

[0104] It should be noted that the specific type of the laundry washing apparatus 100 is not limited in the present disclosure. For example, as one embodiment of the present disclosure, the laundry washing apparatus 100 can be a washing machine, such as a drum washing machine. As another embodiment of the present disclosure, the laundry washing apparatus 100 can also be a dryer, a washer-dryer, etc.

[0105] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0106] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0107] In addition, various different embodiments of the present disclosure can also be combined in any appropriate manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed in the present disclosure.
