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

[0033] Please refer to Figure 1 The embodiments of the present application provide a laundry treating apparatus 100. 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., and the laundry treating apparatus 100 can independently implement any one or more of the functions of washing, drying, dehydration, etc.

[0034] Please refer to Figure 1 and Figure 2 The laundry treating apparatus 100 includes a cabinet, at least two first drum assemblies 30, the first drum assemblies 30 being configured to accommodate laundry, the first drum assemblies 30 having laundry treating cavities in which the laundry to be treated is placed.

[0035] The cabinet includes two side plates which are spaced apart along a first direction. The first direction is generally a horizontal direction, for example, a front-rear direction, a left-right direction, etc. of the laundry treating apparatus. In the embodiments of the present application, the first direction is taken as the left-right direction, and the two side plates described above can be referred to as a left side plate (as shown in FIG. 11) and a right side plate. Figure 5

[0036] All of the first drum assemblies 30 are arranged side by side in the first direction. That is, all of the first drum assemblies 30 are located between the two side plates. For example, in the embodiment in which all of the first drum assemblies 30 are arranged side by side in the left-right direction, one of the first drum assemblies 30 is arranged close to the left side plate 11, and the other first drum assembly 30 is arranged close to the right side plate.

[0037] Exemplarily, the central axes of the two first drum assemblies 30 are parallel to each other and extend in the front-rear direction of the laundry treating apparatus.​

[0038] Please refer to Figure 4 and Figure 5 At least one first drum assembly 30 adjacent to the side plate includes a heating element 33, and the center of the heating element 33 in the first direction is located on one side of the median plane of the first drum assembly 30 adjacent to the corresponding side plate, that is, on the side away from the other first drum assembly 30. The heating element 33 is used to heat the liquid in the first drum assembly 30.

[0039] When the heating element 33 is in a heating state, the heating element 33 can raise the temperature of the liquid in the first drum assembly 30, thereby achieving effects including but not limited to improving cleaning effect, disinfecting and inhibiting bacteria, softening clothes, removing odor, and improving solubility of detergent, etc.

[0040] It should be noted that each first drum assembly 30 can include a heating element 33, or some first drum assemblies 30 include a heating element 33, and the remaining first drum assemblies 30 do not include a heating element 33.

[0041] It should be noted that the above-mentioned at least one first drum assembly 30 adjacent to the side plate includes a heating element 33, which means, for example, that one first drum assembly 30 adjacent to the left side plate 11 includes a heating element 33, and / or one first drum assembly 30 adjacent to the right side plate includes a heating element 33.

[0042] Hereinafter, the left-right direction of the laundry treating apparatus is used instead of the first direction.

[0043] The center of the above-mentioned heating element 33 in the left-right direction of the laundry treating apparatus refers to the midpoint between the two ends of the heating element 33 along the left-right direction of the laundry treating apparatus, and the distance from the midpoint to the two ends of the heating element 33 along the left-right direction is equal. The median plane 30A of the above-mentioned first drum assembly 30 refers to a vertical plane passing through the axis of the first drum assembly 30. That is, the heating element 33 is placed offset with respect to the first drum assembly 30, rather than being disposed directly below the first drum assembly 30. Please refer to Figure 4 and Figure 5 When the first drum assembly 30 on the left side has a heating element 33, the heating element 33 is located below the left side of the first drum assembly 30; when the first drum assembly 30 on the right side has a heating element 33, the heating element is located below the right side of the first drum assembly 30.

[0044] The shape of the heating element 33 is not limited, for example, it can be a plate, a U-shaped tube, a spiral tube, etc.

[0045] In the related art, the heating element is placed directly below the first drum assembly (i.e., the center of the heating element in the left-right direction of the clothes processing apparatus substantially coincides with the median plane of the first drum assembly), which results in a small reserved space below the side of the first drum assembly away from the side plate and a redundant space below the side of the first drum assembly close to the side plate not being utilized, and the space utilization of the clothes processing apparatus is low.

[0046] In the clothes processing apparatus in the embodiments of the present application, the heating element 33 is arranged close to the side plate, i.e., the heating element 33 is offset, so that the lower area between the first drum assembly 30 and the corresponding side plate can be fully utilized to arrange the heating element 33, the space utilization of the clothes processing apparatus 100 is improved, and the structure is relatively compact; in addition, a larger space is left below the first drum assembly 30, which facilitates the installation of other components.

[0047] In some embodiments, the clothes processing apparatus 100 includes a second drum assembly 20.

[0048] The cabinet 10 has at least one installation space 10a, and the second drum assembly 20 and the two first drum assemblies 30 are arranged in the same installation space 10a. It can be understood that the cabinet 10 is used to provide the installation space 10a for the second drum assembly 20 and the first drum assembly 30, and 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, the second drum assembly 20 and the first drum assembly 30 are supported on the cabinet 10, and the cabinet 10 can at least bear the weight of the second drum assembly 20 and its load, and the weight of the first drum assembly 30 and its load.

[0049] Of course, in other embodiments, there can be multiple cabinets 10, and the first drum assembly 30 and the second drum assembly 20 are located in different cabinets 10, and the cabinet 10 where the first drum assembly 30 is located has a left side plate 11 and a right side plate; or, multiple installation spaces 10a are divided in the cabinet 10 by a support or the like, and the first drum assembly 22 and the second drum assembly 21 are located in different installation spaces 10a.

[0050] Exemplarily, the front side of the cabinet 10 has multiple clothes feeding openings, and the second drum assembly 20 and the first drum assembly 30 respectively communicate with corresponding clothes feeding openings, and a user can put or take clothes into or out of the corresponding drum assembly through the clothes feeding opening.

[0051] Please refer to Figure 6In some embodiments, the number of the first drum assemblies 30 is two, and the two first drum assemblies 30 are located above or below the second drum assembly 20. In some embodiments, the two first drum assemblies 30 are arranged side by side above the second drum assembly 20 along the left-right direction, and in this case, the two first drum assemblies 30 are located above the left and right of the second drum assembly 20, respectively. In other embodiments, the two first drum assemblies 30 are arranged side by side below the second drum assembly 20 along the left-right direction, and in this case, the two first drum assemblies 30 are located below the left and right of the second drum assembly 20, respectively.

[0052] The above-mentioned left upper side refers to a position where the center of the first drum assembly 30 is located above and left of the center of the second drum assembly 20, 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 above-mentioned right upper side refers to a position where the center of the first drum assembly 30 is located above and right of the center of the second drum assembly 20, 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 above-mentioned left lower side refers to a position where the center of the first drum assembly 30 is located below and left of the center of the second drum assembly 20, 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 above-mentioned right lower side refers to a position where the center of the first drum assembly 30 is located below and right of the center of the second drum assembly 20, 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 assembly 30 is placed offset relative to the second drum assembly 20, rather than being arranged directly above or below the second drum assembly 20, 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 drawings), and on the other hand leaves space for installing other components.

[0053] The specific structure of the second drum assembly 20 is not limited. For example, the second drum assembly 20 includes an outer tub 31 and an inner drum 32, the outer tub 31 is sleeved outside the inner drum 32, the outer tub 31 is used to hold water, and the inner drum 32 is used to hold laundry. In this embodiment, the inner drum 32 is filled with water through the outer tub 31, and the inner drum 32 can also be referred to as a perforated inner drum 32. In other embodiments, the inner drum 32 is filled with water by itself, and can also be referred to as a non-perforated inner drum 32, and the outer tub 31 can be provided outside the inner drum 32 or not.

[0054] It can be understood that when the first cylinder assembly 30 where the heating element 33 is located is located at the upper left of the second cylinder assembly 20, the heating element 33 is located at the lower left of the first cylinder assembly 30; when the first cylinder assembly 30 where the heating element 33 is located is located at the upper right of the second cylinder assembly 20, the heating element 33 is located at the lower right of the first cylinder assembly 30. The heating element 33 is placed offset relative to the first cylinder assembly 30, which can utilize the lateral space of the first cylinder assembly 30 (including the lower area between the first cylinder assembly 30 and the corresponding side plate), without occupying or less occupying the gap between the outer peripheral surface of the second cylinder assembly 20 and the outer peripheral surface of the first cylinder assembly 30.

[0055] It should be noted that in order to ensure safe operation, the distance between the second cylinder assembly 20 and the first cylinder assembly 30 needs to be no less than a safety distance, so as to ensure that the second cylinder assembly and the first cylinder assembly will not collide during operation.

[0056] In the related art, the heating element is placed directly below the first cylinder assembly (that is, the center of the heating element in the left-right direction of the clothes processing device substantially coincides with the median plane of the first cylinder assembly), which results in the distance of the outer peripheral surface of the second cylinder assembly (or the circumferential surface of the outer barrel of the second cylinder assembly) and the distance of the outer peripheral surface of the first cylinder assembly needing to be further increased to meet the safety distance, which results in the distance between the center of the first cylinder assembly and the center of the second cylinder assembly being further away, requiring a larger installation space. In the embodiments of the present application, the heating element 33 is placed offset relative to the first cylinder assembly 30, and the space occupied by the heating element 33 is moved to one side of the first cylinder assembly 30, so that the heating element 33 does not occupy or less occupies the distance between the outer peripheral surface of the second cylinder assembly 20 and the outer peripheral surface of the first cylinder assembly 30, so that the center of the second cylinder assembly 20 and the center of the first cylinder assembly 30 can be closer, thereby reducing the installation space required by the second cylinder assembly 20 and the first cylinder assembly 30, improving the space utilization of the installation space 10a, and making the structure more compact.

[0057] In addition, the clothes processing device 100 in the embodiments of the present application can improve the temperature of the liquid, and compared with the first cylinder assembly 30 taking hot water from the outside or directly using cold water, it has better cleaning effect, which is beneficial to improve the user experience.

[0058] Exemplarily, in some embodiments, the second cylinder assembly 20 can be used for washing or drying clothes. The second cylinder assembly 20 and the first cylinder assembly 30 can be used for processing the same type of clothes, or can be used for processing different types of clothes. Exemplarily, the second cylinder assembly 20 can process clothes such as outerwear, and the first cylinder assembly 30 can process clothes such as underwear and socks, so as to process corresponding clothes according to different sizes or different washing or drying requirements, thereby increasing the clothes processing efficiency and reliability.

[0059] Exemplarily, in some embodiments, the volume of the second drum assembly 20 is larger than that of the first drum assembly 30. That is, the second drum assembly 20 can accommodate more clothes, i.e., the overall weight of the second drum assembly 20 can be greater than that of the first drum assembly 30. In this way, the second drum assembly 20 can process clothes with large volume or in large quantities, such as coats or sweaters, and the first drum assembly 30 can process clothes with small volume or in small quantities, such as socks, underwear or baby clothes.

[0060] Exemplarily, the number of the first drum assemblies 30 is plural, and the plural first drum assemblies 30 can be used to process the same type of clothes or different types of clothes, so as to enrich the functions of the clothes processing device 100.

[0061] In some embodiments in which the number of the first drum assemblies 30 is plural, the clothes processing device 100 comprises a door seal ring 40 and a drying duct (not shown in the figure), as shown in Figure 1 and Figure 2 The door seal ring 40 is arranged on the front side of the second drum assembly 20, and the drying duct is arranged above the second drum assembly 20 and between the two first drum assemblies 30. The air outlet of the drying duct is connected to the circumferential side of the door seal ring 40, for delivering air flow to the second drum assembly 20. In this way, the drying duct can be arranged in the space between the two first drum assemblies 30, and the structure is compact.

[0062] In some embodiments, the heating element 33 is arranged offset relative to the first drum assembly 30, and part of the heating element 33 is located on one side of the median plane 30A of the first drum assembly 30 close to the side plate. In other embodiments, please refer to Figure 4 and Figure 6 The heating element 33 is entirely located on one side of the median plane 30A of the first drum assembly 30 close to the side plate. In this way, the heating element 33 makes more full use of the lateral space of the first drum assembly 30, and the structure inside the clothes processing device is more compact.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 The first drum assembly 30 comprises an outer barrel 31, an inner drum 32 and a protruding portion 311, and the inner drum 32 is arranged in the outer barrel 31. The protruding portion 311 is arranged on the outer circumferential wall of the outer barrel 31 and protrudes away from the inner drum 32. The interior of the protruding portion 311 defines an avoiding space 311a, and the heating element 33 is arranged in the avoiding space 311a. In this way, the avoiding space 311a is formed to meet the installation requirements of the heating element 33, and the heating element 33 can be kept at a safe distance from the drum wall of the inner drum 32 or the drum wall of the outer barrel 31.

[0064] Exemplarily, in an embodiment, the protruding portion 311 is in a split structure and is sealingly connected with the outer drum 31. The protruding portion 311 is a separate component installed to the outer periphery wall of the outer drum 31. For example, the protruding portion 311 is a sleeve, the sleeve has a through hole in communication with an opening on the outer periphery wall of the outer drum 31, so that the liquid in the outer drum 31 can enter the sleeve, and the heating element 33 is arranged in the sleeve.

[0065] Exemplarily, in an embodiment, the protruding portion 311 is in an integral molding structure with the outer drum 31. The cylinder wall of the outer drum 31 protrudes in a direction away from the inner cylinder 32 to define the protruding portion 311. In this way, the manufacturing process of the protruding portion 311 and the outer drum 31 is simplified, production is facilitated, and the installation operation is simplified. The liquid in the outer drum 31 naturally flows along the cylinder wall and enters the avoiding space 311a formed by the protruding portion 311.

[0066] In some embodiments, referring to Figure 4 and Figure 5 , the avoiding space 311a is located on one side of the median plane 30A of the first cylinder assembly 30 close to the corresponding side plate. That is, taking the first cylinder assembly 30 close to the left side plate 11 as an example, the entire avoiding space 311a is located on the lower left side of the first cylinder assembly 30. Taking the first cylinder assembly 30 close to the right side plate as an example, the entire avoiding space 311a is located on the lower right side of the first cylinder assembly 30. The avoiding space 311a does not extend beyond the median plane 30A of the first cylinder assembly 30 in the opposite direction, so the protruding portion 311 is concentrated on the lower left side or the lower right side of the outer drum 31, which can make the volume of the avoiding space 311a larger and does not occupy too much lateral space of the first cylinder assembly 30.

[0067] In some embodiments, referring to Figure 5 , the intersection (P1 in the figure) between the avoiding space 311a and part of the inner circumferential surface of the outer drum 31 is located at the lowest position of the inner circumferential surface of the outer drum 31. That is, the protruding portion 311 extends from the lowest part of the cylinder wall of the outer drum 31, further making full use of the lateral space of the first cylinder assembly 30. The intersection (P2 in the figure) between the avoiding space 311a and another part of the inner circumferential surface of the outer drum 31 can be located at or near the maximum dimension of the outer drum 31 in the left-right direction, so that the avoiding space 311a is as large as possible.

[0068] In this embodiment, the avoiding space 311a is formed at the lowest part of the cylinder wall of the outer drum 31, so that the liquid in the outer drum 31 is easily concentrated in the avoiding space 311a, so that there is always water in the avoiding space 311a, and the working reliability of the heating element 33 is high, and dry burning and other phenomena are less likely to occur.

[0069] In some embodiments, referring to Figure 4 and Figure 5The minimum distance between the protrusion 311 and the second drum assembly 20 is not less than the minimum distance between the outer tub 31 at a position other than the protrusion 311 and the second drum assembly 20. That is, the minimum gap between the first drum assembly 30 and the second drum assembly 20 is the minimum distance between the outer tub 31 at a position other than the protrusion 311 and the second drum assembly 20, so the first drum assembly 30 and the second drum assembly 20 can be as close as possible, reducing the occupation of the installation space 10a, meeting the safety distance between the two during work, and the structure of the laundry treatment apparatus 100 is more compact.

[0070] In some embodiments, referring to Figure 5 The side wall of the protrusion 311 includes a first wall portion 3111 and a second wall portion 3112 connected to each other, the first wall portion 3111 and the second wall portion 3112 are towards each other, and the second wall portion 3112 is closer to the median plane 30A of the first drum assembly 30 than the first wall portion 3111.

[0071] Exemplarily, the protrusion further includes a third wall portion 3113, the first wall portion 3111 and the second wall portion 3112 are connected to the third wall portion 3113 respectively, the first wall portion 3111 and the second wall portion 3112 both extend along the height direction of the laundry treatment apparatus 100, and the side wall of the protrusion 311 is substantially in the shape of "U", which is conducive to water storage and heating. The third wall portion 3113 can extend along the left-right direction of the laundry treatment apparatus.

[0072] As shown in Figure 5 The dimension of the second wall portion 3112 in the height direction of the laundry treatment apparatus 100 is less than the dimension of the first wall portion 3111 in the height direction. Since the straight surface shape of the cabinet 10 and the curved surface shape of the second drum assembly 20 and the first drum assembly 30 are easy to separate irregular spaces, the protrusion 311 designed in this way can make full use of it, so that the avoidance space 311a has a larger volume as much as possible below the side of the first drum assembly 30, and the shape of the outer tub 31 of the first drum assembly 30 is easy to process and manufacture.

[0073] In some embodiments, the heating element 33 is arranged horizontally. That is, at least the heating surface of the heating element 33 for heating the liquid is in a horizontal state. This is conducive to the heating element 33 being always immersed in the liquid, improving the heating efficiency and reducing the probability of local surface of the heating element 33 being easily dry-burned.

[0074] Exemplarily, the heating element 33 is arranged on the third wall portion 3113 extending along the left-right direction, or the bottom surface of the heating element 33 extends along the third wall portion 3113 and is arranged with a spacing therefrom. In this way, the heating element 33 can be conveniently arranged in a horizontal posture.

[0075] The various embodiments / implementation provided by the present application can be combined with each other in a non-contradictory manner.

[0076] The above only describes preferred embodiments of the present application and is not used to limit the present application. Various changes and modifications can be made by those skilled in the art based on the spirit and principles of the present application.
