In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.

[0035] Please refer to Figure 1 The laundry treating apparatus 100 according to the present application includes a plurality of first drum assemblies 22. The plurality of first drum assemblies 22 are arranged side by side. The plurality means that the number of the first drum assemblies 22 can be two or more. In some embodiments, the axes of the plurality of first drum assemblies 22 are parallel to each other. In other embodiments, the plurality of first drum assemblies 22 are arranged in the left-right direction of the laundry treating apparatus.

[0036] The first drum assembly 22 is configured to accommodate laundry. The first drum assembly 22 is not limited in structure. For example, the first drum assembly 22 includes an outer tub and an inner tub. The outer tub is configured to contain water, and the inner tub is configured to contain laundry. In this embodiment, the inner tub is also referred to as a perforated inner tub because the inner tub contains water through the outer tub. In other embodiments, the inner tub contains water by itself and is also referred to as a non-perforated inner tub. The outer tub can be provided on the outside of the inner tub or can not be provided. The first drum assembly 22 is configured to discharge liquid from the drum after washing, drying, or spinning the laundry. The liquid can be washing water or condensed water.

[0037] It can be understood that the laundry treating apparatus 100 can include various forms, such as a washing machine, a washer-dryer, a washer-dryer set, etc. The laundry treating apparatus 100 can independently implement any one or more of the functions of washing, drying, and spinning.

[0038] Please refer to Figures 2 to 5 The laundry treating apparatus 100 further includes a sump 30, a first drain 42, and a water outlet 43.

[0039] The first drain pipes 42 are multiple in number, and the water inlet ends of the first drain pipes 42 are respectively connected to the first cylinder assemblies 22, and the water outlet ends of the multiple first drain pipes 42 are connected to the water collector 30. The liquid in each first cylinder assembly 22 can enter the water collector 30 through the corresponding first drain pipe 42.

[0040] The water outlet pipe 43 is connected to the water collector 30, and the liquid in the water collector 30 is discharged through the water outlet pipe 43. It should be noted that the water inlet end of the water outlet pipe 43 can be connected to any position of the water collector 30, such as the middle part, the side part, or the inner side of the water collector 30, and then the liquid is guided out, and the specific structure is not limited. The water outlet end of the water outlet pipe 43 is in communication with the external environment, such as a sewer pipe, a washbasin, etc. After the liquid of the multiple first cylinder assemblies 22 enters the water collector 30, it is discharged out of the laundry treatment apparatus 100 through the water outlet pipe 43. The arrowed dashed line in the figure only schematically represents the liquid flow direction for reference.

[0041] The structure of the water collector 30 can be a cylinder or a square box, which is not limited here.

[0042] Therefore, the laundry treatment apparatus 100 provided by the embodiments of the present application has the following advantages. The first drain pipes 42 of the multiple first cylinder assemblies 22 are all connected to the water collector 30, and the liquid is discharged through one water outlet pipe 43, without the need to set an additional water outlet pipe for each first cylinder assembly 22. This can not only shorten the length of the first drain pipes 42, but also reduce the complexity of the pipeline arrangement, facilitating installation and maintenance. In addition, it can also save space for the entire laundry treatment apparatus, which can be used to place other components, thus providing the possibility to improve the use diversity of the laundry treatment apparatus. The water collector 30 can be connected to more drain pipes to realize the drainage of more cylinder assemblies, thus facilitating the expansion of the drainage structure of the laundry treatment apparatus. The water outlet pipe 43 is used to discharge the liquid in the water collector 30, which is directly in communication with the external environment, and the pipeline structure is simple, facilitating drainage.

[0043] In some embodiments, the laundry treatment apparatus further comprises a second cylinder assembly 21 and a second drain pipe 41. The multiple first cylinder assemblies 22 are located above the second cylinder assembly 21, for example, as shown in the figure, and the second drain pipe 41 is connected to the second cylinder assembly 21. Figure 1As shown, when the number of the first drum assemblies 22 is two, they are respectively located at the upper left and upper right of the second drum assembly 21. The upper left means that the center of the first drum assembly 22 is located above and left of the center of the second drum assembly 21, that is, the acute angle between the connecting line of the centers of the two drum assemblies and the horizontal plane is 0°-90°. Similarly, the upper right means that the center of the first drum assembly 22 is located above and right of the center of the second drum assembly 21, that is, the acute angle between the connecting line of the centers of the two drum assemblies and the horizontal plane is 0°-90°. In other words, the first drum assemblies 22 are offset relative to the second drum assembly 21, rather than being arranged directly above the second drum assembly 21, which on the one hand reduces the size of the cabinet 10 in the height direction (i.e., the upward and downward direction in the figure), and on the other hand leaves space for installing other components.

[0044] The volume of the first drum assembly 22 is less than the volume of the second drum assembly 21. That is, the second drum assembly 21 can accommodate more clothes, that is, the overall weight of the second drum assembly 21 can be greater than that of the first drum assembly 22. In this way, the second drum assembly 21 can handle clothes with a larger volume or a large amount of clothes, such as outerwear or coats, and the first drum assembly 22 can handle clothes with a smaller volume or a small amount of clothes, such as socks, underwear, or baby clothes.

[0045] It should be noted that the plurality of first drum assemblies 22 can be used to handle the same type of clothes, or can be used to handle different types of clothes, to enrich the functions of the clothes treatment device 100.

[0046] The water inlet end of the second drain pipe 41 is connected to the second drum assembly 21, and the water outlet end of the second drain pipe 41 is connected to the water collector 30. The liquid in the second drum assembly 21 can enter the water collector 30 through the second drain pipe 41. In this embodiment, the second drum assembly 21 can also drain water through the water collector 30 and finally drain out through the water outlet pipe 43.

[0047] In some embodiments, the clothes treatment device can be a combined washing machine, the second drum assembly 21 (which can be referred to as a large drum) and the plurality of first drum assemblies 22 (which can be referred to as small drums) are combined together, and collectively drain water through the water collector 30 and the water outlet pipe 43. Compared with arranging a separate water outlet pipe for each drum assembly to drain water, this way greatly simplifies the water drainage structure, facilitates installation and maintenance, and reduces the occupation of the clothes treatment device to the user's living space.

[0048] In some embodiments, please refer to Figure 1The laundry treating apparatus further comprises a cabinet 10 having an installation space 10a inside. The first drum assembly 22, the second drum assembly 21, the water collector 30, the first drain pipe 42 and the second drain pipe 41 are all located in the installation space 10a. That is, the above-mentioned components are located in the same installation space 10a. It can be understood that the cabinet 10 has sufficient structural strength to serve as a force-bearing member, has the functions of vertical load bearing and resisting external impact, and the first drum assembly 22 and the second drum assembly 21 are supported by the cabinet 10, which can at least bear the weight of the first drum assembly 22 and its load, and the weight of the first drum assembly 22 and its load.

[0049] The components are arranged in the same installation space 10a, which is beneficial to reduce the size of the cabinet 10 and reduce the space occupation of the laundry treating apparatus.

[0050] Of course, in other embodiments, there can be multiple cabinets 10, and the first drum assembly 22 and the second drum assembly 21 are located in different cabinets; or, the cabinet 10 is divided into multiple installation spaces 10a by supports or other structures, and the first drum assembly 22 and the second drum assembly 21 are located in different installation spaces 10a. The water collector 30, the first drain pipe 42 and the second drain pipe 41 adjust their arrangement modes according to the specific structure.

[0051] In some embodiments, referring to Figure 2 and Figure 4 , the position of the water outlet end of any one of the first drain pipes 42 is lower than the position of the water outlet end of the second drain pipe 41. In this way, the water outlet end of the first drain pipe 42 and the water outlet end of the second drain pipe 41 are not at the same height, and when the second drum assembly 21 corresponding to the second drain pipe 41 drains, the liquid discharged into the water collector 30 will flow out along the water outlet pipe 43 and is not easy to flood back into the first drain pipe 42, thereby reducing the influence on the first drum assembly 22.

[0052] It should be noted that the position of the water outlet end of the first drain pipe 42 is lower than the position of the water outlet end of the second drain pipe 41 means that the lowest point of the water outlet end of the first drain pipe 42 is lower than the lowest point of the water outlet end of the second drain pipe 41. If the water collector 30 floods, the liquid level will first overflow the lowest point of the first drain pipe 42.

[0053] Of course, in other embodiments, the water outlet end of the second drain pipe 41 can also be lower than the water outlet end of all the first drain pipes 42, so that when the first drum assembly 22 corresponding to the first drain pipe 42 drains, it is not easy to flow back into the second drain pipe 41.

[0054] In some embodiments, referring to Figure 3 and Figure 5, the water inlet end of the second drain pipe 41 is lower than the water outlet end of the second drain pipe 41, and the laundry treatment apparatus 100 further includes a drain pump (not shown) provided to the second drain pipe 41, the drain pump being configured to pump the liquid of the second drain pipe 41. The liquid of the second tub assembly 21 can be actively pumped into the sump 30 by the drain pump through the second drain pipe 41, that is, in this embodiment, the second tub assembly 21 adopts the "upper drain" drainage mode, so that the sump 30 can be arranged at a higher position in the laundry treatment apparatus 100, and the water outlet pipe 43 can extend downward along the height direction of the laundry treatment apparatus 100, which facilitates the drainage of the water outlet pipe 43 and saves space during installation of the laundry treatment apparatus 100, and the laundry treatment apparatus 100 can be more flexibly arranged in a relatively compact space such as a bathroom or a kitchen. The "upper drain" mode can make the drainage of the second tub assembly 21 more smooth and complete, and keep the tub clean and fresh.

[0055] It should be noted that in the embodiment in which the volume of the second tub assembly 21 is greater than the volume of the first tub assembly 22, the drainage flow of the second tub assembly 21 is larger, and at this time, the water level in the sump 30 rises faster, and the position of the water outlet pipe 43 of the second drain pipe 41 is higher than the position of the water outlet end of all the first drain pipes 42, which can effectively reduce the backflow of the liquid in the sump 30 to the second drain pipe 41.

[0056] In some embodiments, referring to Figure 2 and Figure 4 , the position of the part of the second drain pipe 41 is higher than the highest position of the second tub assembly 21. In this way, the water outlet pipe 43 is immersed in the external liquid (for example, the liquid in the sink), and when the second drain pipe 41 drains, the liquid column formed between the part of the second drain pipe 41 higher than the highest position of the second tub assembly 21 and the water outlet pipe 43 is short, the liquid surface pressure in the second tub assembly 21 and the liquid surface pressure of the liquid in which the water outlet end is immersed are less different, and the siphon phenomenon is less likely to occur, reducing the probability of siphoning external liquid into the second tub assembly 21 after the second drain pipe 41 finishes draining.

[0057] In some embodiments, referring to Figure 3 and Figure 5The laundry treating apparatus 100 further comprises a drain valve 50 disposed in the first drain pipe 42, the drain valve 50 being configured to open or close the first drain pipe 42. It can be understood that when the first drain pipe 42 is draining, the drain valve 50 is open, and liquid can flow through the drain valve 50; when the first drain pipe 42 is not draining, the drain valve 50 is closed, so that liquid in the water collector 30 is difficult to flow into the first tub assembly 22 through the drain valve 50; when the second tub assembly 21 is draining, the drain valve 50 is closed, and liquid drained from the second tub assembly 21 will not flow into the first tub assembly 22; and the second tub assembly 21 and the first tub assembly 22 will not affect each other when both of them are draining.

[0058] In some embodiments, as shown in Figure 3 and Figure 5 , the water inlet end of the first drain pipe 42 is located higher than the water outlet end of the first drain pipe 42. In this way, when the first drain pipe 42 is draining, liquid can flow into the water collector 30 from the first tub assembly 22 by gravity, that is, the first tub assembly 22 adopts a "bottom draining" draining mode, which is simple and reliable.

[0059] It should be noted that in the embodiments in which the volume of the second tub assembly 21 is greater than the volume of the first tub assembly 22, the first tub assembly 22 has a small draining flow rate, and can meet the design requirements by draining in the "bottom draining" mode, and can greatly simplify the complexity of the draining structure of the laundry treating apparatus 100 and improve the reliability.

[0060] In some embodiments, as shown in Figure 2 and Figure 4 , the position of the part of the first drain pipe 42 is lower than the highest position of the second tub assembly 21. In this way, the water inlet end and the water outlet end of the first drain pipe 42 have a large drop, which facilitates fast draining.

[0061] In some embodiments, as shown in Figures 2 to 5 , the water inlet end of the water outlet pipe 43 is located lower than the water outlet end of the second drain pipe 41 and lower than the water outlet end of one or more first drain pipes 42. That is, the water inlet end of the water outlet pipe 43 is located lower, and no matter when the second drain pipe 41 is draining or when the first drain pipe 42 is draining, the liquid to be drained can quickly flow into the water outlet pipe 43 through the water inlet end of the water outlet pipe 43, and the water collector 30 has a small liquid storage, and the draining is more thorough.

[0062] It should be noted that the position of the water inlet end of the water outlet pipe 43 being lower than the position of the water outlet end of the second drain pipe 41 and lower than the position of the water outlet end of the one or more first drain pipes 42 refers to the lowest point of the water inlet end of the water outlet pipe 43 being lower than the lowest point of the water outlet end of the second drain pipe 41 and lower than the lowest point of the water outlet end of the first drain pipe 42, in case the liquid in the water collector 30 overflows, the liquid level will first overflow the lowest point of the water inlet end of the water outlet pipe 43.

[0063] In some embodiments, the water collector 30 has a bottom wall extending downwardly from a direction away from the water inlet end of the water outlet pipe 43 to a direction close to the water inlet end of the water outlet pipe 43. Here, the direction away from the water inlet end of the water outlet pipe 43 to the direction close to the water inlet end of the water outlet pipe 43 can refer to the left-right direction, i.e. the bottom wall extends downwardly from the left to the right direction. In this way, the liquid in the water collector 30 tends to flow and concentrate towards the water inlet end of the water outlet pipe 43 under the action of gravity, accelerating the drainage and being less likely to remain.

[0064] In some embodiments, referring to Figure 3 , the water collector 30 comprises a first extension 31 and a second extension 32 connected to each other, the first extension 31 extends along the left-right direction of the laundry treatment apparatus 100, and the second extension 32 extends upwardly from one end of the first extension 31, and the projection of the water collector 30 along the front-rear direction has a profile shape substantially in the form of “L”.

[0065] The water outlet end of the second drain pipe 41 is connected to the second extension 32, and the water outlet end of the one or more first drain pipes 42 is connected to the first extension 31, so that the water outlet end of the second drain pipe 41 can be positioned relatively high, and the water outlet ends of the plurality of first drain pipes 42 can be connected together, and the first extension 31 extends along the left-right direction with a relatively long length, which can reduce the length of the pipe material required for connecting the first drain pipe 42 to the water collector 30, facilitating installation.

[0066] Of course, the shape profile of the water collector 30 can also be rectangular (as shown in Figure 3 ) or pipe-shaped, or other shapes.

[0067] The drainage structure of the laundry treatment apparatus 100 in a specific embodiment of the present application will be described below.

[0068] Referring to Figure 3 and Figure 5With the number of the first cylinder assemblies 22 being two, the two first cylinder assemblies 22 are respectively located at the upper left and upper right of the second cylinder assembly 21. The water collector 30 is located at the upper half of the second cylinder assembly 21, the water inlet end of the second drain pipe 41 is led out from the lower half of the second cylinder assembly 21 and partially extends upward, and the water outlet end of the second drain pipe 41 is connected to the water collector 30 from top to bottom. The water inlet end of the first drain pipe 42 is led out from the first cylinder assembly 22 rearward, and the water outlet end of the first drain pipe 42 is connected to the water collector 30 in the horizontal direction. The position of the water outlet end of the second drain pipe 41 is higher than the positions of the water outlet ends of the two first drain pipes 42, the water inlet end of the outlet pipe 43 is connected to the water collector 30 in the horizontal direction, and the position of the water inlet end thereof is lower than the water outlet end of the second drain pipe 41 and also lower than the water outlet end of the first drain pipe 42. The water outlet end of the outlet pipe 43 can extend out of the cabinet 10 to discharge the liquid in the water collector 30 to the external environment.

[0069] The various embodiments / implementation forms provided in the present application can be combined with each other without producing contradictions, if possible.

[0070] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
