DETAILED DESCRIPTION

[0049] A detailed description of specific embodiments of the disclosure follows, with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative and explanatory in nature and are not intended to limit the disclosure.

[0050] In the disclosure, unless otherwise stated, the orientation words such as "upper, lower" can refer to the upper, lower of the drawing, "left, right" can refer to the left, right of the drawing, "front, back" can refer to the side of the opening of the first drum or the second drum as the front, and the side opposite to the opening as the back. "Inner, outer" refers to the outline of the part itself. In addition, it should be noted that the terms such as "first, second" are used 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.

[0051] The inventor has found, through research, that a laundry treating apparatus vibrates during a washing process, and as the functions of the laundry treating apparatus become increasingly diversified, the number of components within the laundry treating apparatus significantly increases. For example, a double drum laundry treating apparatus requires a large number of components and occupies a large amount of space, and reducing the size of the double drum laundry treating apparatus, for example, to the size of a conventional single drum laundry treating apparatus, requires reducing the size of at least one drum and requires centralized arrangement of components on the drum. Due to the size limitation of the laundry treating apparatus, when the drum vibrates, for example, during a washing process, the two drums are likely to collide with each other, and / or the drum or the components thereon are likely to rub against or collide with the housing 1.

[0052] To solve the above technical problem, according to one embodiment of the disclosure, as shown in FIGS. 1 to 19, a laundry treating apparatus 100 is provided. The laundry treating apparatus 100 can include a housing 1, and a first drum assembly 2 and a second drum assembly 3 located within the housing 1. At least one of the housing 1, the first drum assembly 2, and the second drum assembly 3 is provided with a relief portion 4. The relief portion 4 is used to avoid at least one of the housing 1, the first drum assembly 2, and the second drum assembly 3.

[0053] With the above technical solution, at least one of the housing 1, the first drum assembly 2, and the second drum assembly 3 is provided with a relief portion 4, which is used to avoid at least one of the housing 1, the first drum assembly 2, and the second drum assembly 3. It can be understood that the above technical solution of the disclosure can achieve, on the one hand, avoiding collision between the first drum assembly 2 and the second drum assembly 3, and on the other hand, avoiding collision between the first drum assembly 2 and / or the second drum assembly 3 and the housing 1, thereby improving the safety and reliability of the laundry treating apparatus 100.

[0054] Among them, when the relief portion is provided on the housing 1, at least one of the first drum assembly 2 and the second drum assembly 3 can be avoided, when the relief portion is provided on the first drum assembly 2, the second drum assembly 3 or the housing 1 can be avoided, and when the relief portion is provided on the second drum assembly 3, the first drum assembly 2 or the housing 1 can be avoided.

[0055] In some embodiments, as shown in FIGS. 6, 7, 8, 9, 14, 15, 16, and 19, the first drum assembly 2 includes a first drum 21. The second drum assembly 3 includes a second drum 31. At least one of the first drum 21 and the second drum 31 is provided with a relief portion 4 for avoiding the other.

[0056] By the above technical solution, one of the first drum 21 and the second drum 31 is provided with the avoiding portion 4 for avoiding the other, for example, the avoiding portion 4 is provided on the first drum 21, so that when the laundry treatment apparatus 100 vibrates during the washing process, for example, the first drum 21 and / or the second drum 31, the collision between the first drum 21 and the second drum 31 during the washing process can be avoided by the provision of the avoiding portion 4, thereby improving the safety and stability of the laundry treatment apparatus 100.

[0057] Of course, it can be understood that the structure of the above-mentioned avoiding portion 4 provided on the first drum 21 alone is exemplary, and in other embodiments, the avoiding portion 4 can also be provided on the second drum 31 alone, or the avoiding portion 4 can be provided on both the first drum 21 and the second drum 31, as long as the first drum 21 and the second drum 31 can avoid each other during the washing process, for example, to avoid the collision between the first drum 21 and the second drum 31.

[0058] In order to avoid the collision between the first drum 21 and the second drum 31 during washing, in some embodiments, as shown in FIGS. 5, 6, 7 and 8, the minimum distance between the avoiding portion 4 on the first drum 21 and the second drum 31 and / or the avoiding portion 4 on the second drum 31 is greater than a preset distance. And / or, the minimum distance between the avoiding portion 4 on the second drum 31 and the first drum 21 and / or the avoiding portion 4 on the first drum 21 is greater than a preset distance. Exemplarily, the avoiding portion 4 is provided on both the first drum 21 and the second drum 31, the avoiding portion 4 on the first drum 21 and the avoiding portion 4 on the second drum 31 can be relatively arranged or arranged in a circumferential direction or in an axial direction, and the minimum distance between the avoiding portion 4 on the first drum 21 and the avoiding portion 4 on the second drum 31 is greater than a preset distance, for example, the preset distance can be 3mm-40mm, in this way, by providing the avoiding portion 4 on the first drum 21 and the avoiding portion 4 on the second drum 31 and the minimum distance between the two avoiding portions 4 being greater than the preset distance, the first drum 21 and the second drum 31 can have enough space during washing to avoid the collision between the first drum 21 and the second drum 31.

[0059] In some embodiments, the preset distance is determined according to the amplitude of the first drum 21 and / or the second drum 31. By determining the preset distance according to the amplitude of the first drum 21 and the second drum 31, such a design is more accurate and representative, and thus the installation position of the first drum 21 and the second drum 31 can be reasonably and accurately controlled.

[0060] It can be understood that the embodiment that the minimum distance between the avoiding portion 4 on the first barrel 21 and the avoiding portion 4 on the second barrel 31 is greater than the preset distance is illustrative, in other embodiments, the avoiding portion 4 on the first barrel 21 can be used to avoid the second barrel 31, the avoiding portion 4 on the second barrel 31 can avoid the first barrel 21, the two avoiding portions 4 are used to avoid the first barrel 21 and the second barrel 31 respectively, and the minimum distance between the avoiding portion 4 on the first barrel 21 and the second barrel 31 is greater than the preset distance, the minimum distance between the avoiding portion 4 on the second barrel 31 and the first barrel 21 is greater than the preset distance, so that the first barrel 21 and the second barrel 31 have enough space during washing, and the first barrel 21 and the second barrel 31 are prevented from colliding.

[0061] In addition, the preset distance can be optimized according to the size and mounting position of the shell 1, the first barrel 21 and the second barrel 31, for example, the preset distance in the embodiment can also be 15-30 mm, and further, the preset distance can also be 25 mm. In this way, the range of the preset distance is selected according to the specific working condition, so that the first barrel 21 and the second barrel 31 have enough space during washing, and the first barrel 21 and the second barrel 31 are prevented from colliding.

[0062] In addition, illustratively, before the avoiding portion 4 is arranged, the avoiding portion 4 is arranged at at least one of the two positions closest to the first barrel 21 and the second barrel 31 to increase the distance between the two positions to avoid collision. It can be understood that after the avoiding portion 4 is arranged, the distance between the two positions can still be the minimum distance between the first barrel 21 and the second barrel 31, in addition to arranging the avoiding portion 4 at at least one of the two positions, it is obvious that another avoiding portion 4 can also be arranged at other positions, and the present disclosure does not make specific limitation thereto.

[0063] In addition, in order to adapt the first barrel 21 and the second barrel 31 to the mounting space of the shell 1, the distance between the first center axis of the first barrel 21 and the second center axis of the second barrel 31 can be 355-404 mm, preferably, the distance between the first center axis of the first barrel 21 and the second center axis of the second barrel 31 can be 367-394 mm, and further, the distance between the first center axis of the first barrel 21 and the second center axis of the second barrel 31 can be 367-377 mm.

[0064] It should be noted that the laundry treating apparatus mentioned in the present disclosure can be a double-barreled washing machine, a double-barreled dryer, a double-barreled washer-dryer, etc. including the first barrel 21 and the second barrel 31. In the present embodiment, the double-barreled washer-dryer is taken as an example, which includes the housing 1. The size of the housing 1 is the size of a conventional single-barreled laundry treating apparatus, for example, the width of the housing 1 is 550mm-650mm, and the height of the housing 1 is 800mm-900mm. The sizes of the first barrel 21 and the second barrel 31 can be different, for example, the outer diameter of the first barrel 21 is greater than that of the second barrel 31, and the ratio of the outer diameter of the first barrel 21 to that of the second barrel 31 is 2.8-3.1. For example, the outer diameter of the first barrel 21 can be 530mm-543mm, and the outer diameter of the second barrel 31 can be 175mm-185mm, so that the laundry can be distinguished by the two barrels of different sizes. The outer diameter of the first barrel 21 can be the outer diameter of the first outer barrel in the first barrel 21, and the outer diameter of the second barrel 31 can be the outer diameter of the second outer barrel in the second barrel 31. In addition, the first barrel 21 further includes a first inner barrel for washing or drying laundry, etc., and the second barrel 31 further includes a second inner barrel for washing or drying laundry, etc. Of course, the double-barreled washer-dryer provided in the present embodiment includes the necessary components of the double-barreled washer-dryer in addition to the housing 1, the first barrel assembly 2 and the second barrel assembly 3 mentioned above, such as various harness cables, power motors, etc. The above-mentioned harness cables and power motors can adopt conventional devices, and the specific structure thereof will not be described herein.

[0065] In some embodiments, the size of the avoiding part 4 on the first barrel 21 and / or the second barrel 31 is determined according to the amplitude of the first barrel 21 and / or the second barrel 31. The size of the avoiding part 4 is determined by the amplitude of the first barrel 21 and the second barrel 31. Such a design is more accurate and representative, and can reasonably and accurately control the installation position of the first barrel 21 and the second barrel 31.

[0066] Optionally, in order to adapt the first drum 21 and the second drum 31 to the installation space of the housing 1, the first central axis of the first drum 21 is arranged in parallel with the second central axis of the second drum 31, and the second central axis is above the first central axis. In this way, that is, the second drum 31 is offset relative to the first drum 21, the size (for example, the outer diameter) of the second drum 31 can be expanded, thereby expanding the volume of the second drum 31 to improve its washing or drying capacity. In this arrangement of the first drum 21 and the second drum 31, the second drum 31 is above the first drum 21. In this embodiment, considering the laundry processing capacity of the laundry treatment apparatus 100, the laundry processing scenario, and the structural size of the laundry treatment apparatus 100, and the like, this arrangement can reasonably realize the position arrangement of the first drum 21 and the second drum 31. Optionally, the size of the first drum 21 is greater than the size of the second drum 31, that is, the second drum 31 can be arranged above the first drum 21 without increasing the structural size of the laundry treatment apparatus 100, effectively utilizing the idle space of the laundry treatment apparatus 100, thereby being able to increase the laundry processing capacity of the laundry treatment apparatus 100 and being able to adapt the laundry treatment apparatus 100 to different laundry processing scenarios, improving the user experience.

[0067] It should be noted that the sizes of the first drum 21 and the second drum 31 can be the same or different, which is not limited herein, and those skilled in the art can adjust according to the actual situation. The first drum 21 and the second drum 31 can be arranged to adapt to different laundry processing scenarios. For example, the first drum 21 and the second drum 31 can be used to process clothes that are prone to color mixing, such as dark or light clothes, to avoid dyeing problems during laundry processing and improve user experience. Alternatively, the first drum 21 and the second drum 31 can be used to process clothes of different materials to separately set the corresponding washing intensity and washing time. The above different laundry processing scenarios of the first drum 21 and the second drum 31 are only illustrative, and those skilled in the art can adjust to any suitable processing scenario, which is not limited herein.

[0068] Further, in the vertical direction, the horizontal plane on which the lowest point of the second drum 31 is located is lower than the horizontal plane on which the highest point of the first drum 21 is located; and / or, in the horizontal direction, the distance between the point closest to the vertical plane of the first central axis of the first drum 21 and the vertical plane is less than the outer diameter of the first drum 21. In this way, the first drum 21 and the second drum 31 have partially overlapping areas in the vertical direction and in the horizontal direction, so that the first drum 21 and the second drum 31 can be arranged more compactly, further expanding the size of the first drum 21 and the second drum 31.

[0069] In some embodiments, the front part of the first drum 21 is provided with a first door body for opening to put laundry into the first drum 21, and the rear part is provided with a first driving motor for driving the first inner drum of the first drum 21 to rotate. The front part of the second drum 31 is also provided with a corresponding second door body for opening to put laundry into the second drum 31, and the rear part is provided with a second driving motor for driving the second inner drum of the second drum 31 to rotate. Such an arrangement can cause the front part of the first drum 21 and the front part of the second drum 31 to have a large vibration amplitude and be more likely to collide during washing. Therefore, in some embodiments, the first drum 21 and the second drum 31 can each be provided with a relief portion 4. The distance between the relief portion 4 on the first drum 21 and the front end of the first drum 21 is less than the distance between the relief portion 4 on the first drum 21 and the rear end of the first drum 21; and / or the distance between the relief portion 4 on the second drum 31 and the front end of the second drum 31 is less than the distance between the relief portion 4 on the second drum 31 and the rear end of the second drum 31.

[0070] When the front ends of the first drum 21 and the second drum 31 need to be relieved, the relief portion 4 on the first drum 21 is at least partially located at the front end of the first drum 21; and / or the relief portion 4 on the second drum 31 is at least partially located at the front end of the second drum 31. In addition, the front end of the second drum 31 protrudes forward of the front end of the first drum 21 in the front-rear direction. In the front-rear direction, the relief portion 4 on the second drum 31 is at least partially located in front of the relief portion 4 on the first drum 21. By arranging the front end of the first drum 21 and the front end of the second drum 31 to be offset in the front-rear direction, and by arranging the relief portion 4 on the second drum 31 to be at least partially in front of the relief portion 4 on the first drum 21, further space can be provided for the front end of the first drum 21 and the front end of the second drum 31 to avoid collision between the first drum 21 and the second drum 31 during washing, thereby improving the reliability of the laundry treatment apparatus 100.

[0071] In some embodiments, the first drum 21 has a first central axis. The second drum 31 has a second central axis. The relief 4 on the first drum 21 is located at the intersection between the line connecting the first central axis and the second central axis and the outer wall of the first drum 21. In this way, the second drum 31 can be avoided by the relief 4 provided on the first drum 21, so as to avoid collision between the first drum 21 and the second drum 31 during the washing process, thereby improving the reliability of the laundry treatment apparatus 100. Accordingly, in order to further avoid collision between the first drum 21 and the second drum 31, the relief 4 on the second drum 31 is located at the intersection between the line connecting the first central axis and the second central axis and the outer wall of the second drum 31.

The second avoiding part 42 is used to avoid at least one of the first barrel 21, the first additional part 22, the second additional part 32 and the housing 1. And / or, the avoiding part 4 includes a third avoiding part 43 arranged on the housing 1. The third avoiding part 43 is used to avoid at least one of the first barrel 21, the second barrel 31, the first additional part 22 and the second additional part 32.

[0075] In summary, the first avoiding part 41 arranged on the first barrel 21 can effectively avoid at least one of the second barrel 31, the second additional part 32, the first additional part 22 and the housing 1. Correspondingly, the second avoiding part 42 arranged on the second barrel 31 can effectively avoid at least one of the first barrel 21, the first additional part 22, the second additional part 32 and the housing 1. The third avoiding part 43 arranged on the housing 1 can effectively avoid at least one of the first barrel 21, the second barrel 31, the first additional part 22 and the second additional part 32.

[0076] The avoiding concept of the present application is specifically illustrated by taking the first avoiding part 41 arranged on the first barrel 21 as an example.

[0077] Alternatively, in order to facilitate the first barrel 21 to avoid the second barrel 31, in some implementable manners, the avoiding part 4 can include a first avoiding part 41 arranged on the first barrel 21. The first avoiding part includes an avoiding recess 411 recessed in the first barrel 21 or the second barrel 31. As shown in FIGS. 5, 6 and 7, the avoiding recess 411 includes a first avoiding recess 411a arranged on a first outer barrel 211 of the first barrel 21. The first outer barrel 211 includes an outer circumferential surface 211a and a front end surface 211b. The first avoiding recess 411a is arranged at the intersection of the outer circumferential surface 211a and the front end surface 211b. The first avoiding recess 411a is located above the horizontal plane of the first central axis of the first barrel 21 and on the side of the vertical plane of the first central axis of the first barrel 21 facing the second barrel 31. Thus, by arranging the first avoiding recess 411a on the first barrel 21, an avoiding space can be formed with the second barrel 31 to avoid collision between the first barrel 21 and the second barrel 31 during the washing process, thereby improving the reliability of the clothes treatment apparatus.

[0078] In addition, the avoidance groove 411 can further include a second avoidance groove 411b, the second avoidance groove 411b is arranged on the front end face 211b of the first outer cylinder 211 of the first cylinder body 21, the front end face 211b of the first outer cylinder 211 is provided with a reinforcing rib 211c for reinforcing the end structure strength of the first outer cylinder 211, part of the reinforcing rib 211c is concave towards the first central axis of the first cylinder body 21 to form the second avoidance groove 411b, the second avoidance groove 411b is located above the horizontal plane where the first central axis of the first cylinder body 21 is located, and is located on the side of the first central axis of the first cylinder body 21 towards the second cylinder body 31. Through the arrangement of the second avoidance groove 411b, the first cylinder body 21 and the second cylinder body 31 can be avoided from colliding with each other due to vibration during washing, and the reliability of the clothes treatment equipment is improved.

[0079] The avoidance concept of the present application will be described in detail taking the second avoidance part 42 arranged on the second cylinder body 31 as an example.

[0080] In some embodiments, the avoidance part 4 can include a second avoidance part 42 arranged on the second cylinder body 31. The second avoidance part 42 can include a groove 421. The groove 421 can include a first groove 421a arranged on the connecting part 312, the second outer cylinder 311 is provided with an annular protrusion 311a extending radially outward, the connecting part 312 is arranged on the annular protrusion 311a, the connecting part 312 and the cylinder ring 313 are at least partially located in front of the first cylinder body 21 in the front-rear direction, the number of connecting parts 312 is multiple and is arranged in a circumferential direction interval around the central axis of the second cylinder body 31, the middle part of the connecting part 312 is provided with a mounting hole, the cylinder ring 313 can be a substantially circular ring, the cylinder ring 313 is provided with a matching hole matched with the connecting part 312, and a fastener passes through the opposite mounting hole and the matching hole so as to fixedly connect the cylinder ring 313 with the connecting part 312, thereby fixing the cylinder ring 313 on the second outer cylinder 311. Through the first groove 421a arranged on the connecting part 312, the annular protrusion 311a can be avoided from colliding with the first cylinder body 21, and the reliability of the clothes treatment equipment 100 is improved.

[0081] In addition, the groove 421 can further include a second groove 421b arranged on the annular protrusion 311a. Exemplarily, the second groove 421b is arranged at the junction of the outer peripheral wall and the side wall of the annular protrusion 311a, and the first groove 421a and the second groove 421b are spaced apart in the circumferential direction and spaced apart in the axial direction of the second cylinder body 31. In this way, through the arrangement of the second groove 421b, the first cylinder body 21 and the second cylinder body 31 can be avoided from colliding with each other during washing on the basis of the first avoidance groove 411a, the second avoidance groove 411b and the first groove 421a, and the reliability of the clothes treatment equipment 100 is improved.

[0082] In some embodiments, the groove 421 can further include a third groove 421c arranged on the second barrel 31, which can be used to avoid the second additional member 32 or the shell 1. For example, in the exemplary embodiment of the present disclosure, the third groove 421c can be used to avoid the second additional member 32, such as the water supply flow path 5 (to be mentioned below), so that the water supply flow path 5 can be avoided from rubbing or colliding with the second outer barrel, and the water supply flow path 5 can also be kept at a distance from the shell to avoid rubbing or colliding with the shell.

[0083] The avoidance concept of the present application will be described in detail taking the third avoidance part 43 arranged on the shell 1 as an example.

[0084] In some embodiments, as shown in FIGS. 11, 12, 13, 14, 15 and 16, the shell 1 includes a front plate 11, a rear plate 12, two side plates 13 connected between the front plate 11 and the rear plate 12, and a top plate 14 and a bottom plate 15 connected between the front plate 11 and the rear plate 12. The third avoidance part 43 is arranged on at least one of the front plate 11, the side plate 13, the top plate 14, the bottom plate 15 and the rear plate 12. It should be noted that the third avoidance part 43 is only taken as an example arranged on the front plate 11 in the technical solution of the present disclosure. However, it should be understood that the third avoidance part 43 can also be arranged on at least one of the side plate 13, the top plate 14, the bottom plate 15 and the rear plate 12 to avoid the first barrel 21, the second barrel 31, the first additional member 22 and the second additional member 32. In addition, arranging the corresponding third avoidance part 43 on the side plate 13, the top plate 14 and the bottom plate 15 other than the front plate 11 can also achieve the avoidance purpose for other component structures of the clothes treatment device 100 arranged in the shell 1, thereby improving the use applicability and reliability of the shell 1.

[0085] In some embodiments, as shown in FIGS. 15 and 16, the front plate 11 has a first flange 111. The third avoiding portion 43 includes an avoiding groove 431 arranged on the first flange 111. The third avoiding portion 43 formed by the first flange 111 can avoid friction or collision between the first flange 111 and the first cylinder 21 and / or the second cylinder 31. The third avoiding portion 43 is arranged on the first flange 111, which is a reasonable arrangement position, and forming the third avoiding portion 43 on the first flange 111 is also conducive to simplifying the forming process of the third avoiding portion 43. The arrangement position of the first flange 111 can be arbitrary, for example, the first flange 111 can be arranged at the top of the front plate 11 for connecting the top plate 14, which facilitates the connection between the front plate 11 and the top plate 14, and the first flange 111 can also increase the connection area between the front plate 11 and the top plate 14, thereby improving the connection reliability. Similarly, the first flange 111 can also be arranged at the side of the front plate 11 for connecting the side plate 13, and / or the first flange 111 can also be arranged at the bottom of the front plate 11 for connecting the bottom plate 15, and the disclosure is not limited thereto. The second additional component 32 includes at least one of the water supply flow path 5, the drying flow path 6, the steam exhaust flow path, and the water exhaust flow path, and part of the second additional component 32 is located in the avoiding groove 431.

[0086] It should be noted here that, considering the arrangement position of the second cylinder 31 and the arrangement manner of the second additional component 32 in the shell 1, arranging the avoiding groove 431 on the first flange 111 connected to the top plate 14 can reasonably utilize the space inside the shell 1, and the avoiding groove 431 can effectively avoid the second additional component 32.

[0087] In some embodiments, as shown in FIG. 16, the avoiding groove 431 on the first flange 111 can include a first avoiding groove 431a. The second additional component 32 can include the water supply flow path 5. Part of the water supply flow path 5 is located in the first avoiding groove 431a. And / or, the avoiding groove 431 on the first flange 111 can include a second avoiding groove 431b. The second additional component 32 can include the drying flow path 6. Part of the drying flow path 6 is located in the second avoiding groove 431b. Such an arrangement manner can achieve the avoiding purpose of the corresponding second additional component 32 without increasing the complexity of the forming process of the avoiding groove 431, thereby reducing the manufacturing cost of the clothes treatment equipment 100. At the same time, the targeted avoiding of the second additional component 32 also avoids the problem of reducing the structural strength of the shell 1 caused by opening a large area of avoiding in the shell 1.

[0088] In some embodiments, as shown in FIGS. 11 and 12, the water supply flow path 5 is communicated with the second drum 31 from above the second drum 31. The drying flow path 6 is located on the side of the second drum 31 facing the first drum 21 in the horizontal direction and above the first drum 21. In this embodiment, it can be understood that, in order to further achieve the pretreatment effect on the clothes, the water supply flow path 5 is usually arranged at the top of the second drum 31 to achieve the purpose of introducing the treatment medium into the second drum 31 from top to bottom, so that the treatment medium can gradually penetrate the clothes from top to bottom during the water supply process, so as to ensure that the clothes in the second drum 31 can be effectively pretreated during the water supply process. Compared with the water supply process from bottom to top, the process is prone to the problem that the water level in the second drum 31 is not enough to cause the clothes to be unable to be reliably pretreated. It needs to be explained that the pretreatment here can be understood as spraying, soaking or flushing by the treatment medium. In this case, correspondingly, the first avoiding groove 431a of the present disclosure is arranged on the first flange 111 connected with the top plate 14 of the front plate 11. The arrangement position of the first avoiding groove 431a can correspond to the water supply flow path 5, thereby improving the avoiding reliability. Further, the arrangement position of the drying flow path 6 can also reasonably correspond to the avoiding groove 431 arranged on the shell 1 without interfering with the normal work of the water supply flow path 5, thereby improving the avoiding reliability of the third avoiding part 43. In addition, the water supply flow path 5 can fully utilize the space above the second drum 31, and the drying flow path 6 can fully utilize the space beside the second drum 31, thereby improving the space utilization rate.

[0089] In some embodiments, as shown in FIG. 16, the first flange 111 can include a first plate body 111a extending from the front plate 11 towards the inside of the shell 1, and a second plate body 111b extending from the first plate body 111a towards the top plate 14. The avoiding groove 431 on the first flange 111 is formed on at least one of the first plate body 111a and the second plate body 111b. The first plate body 111a and the second plate body 111b can be formed in a manner that a bending part is formed at the connection between the first plate body 111a and the second plate body 111b, for example, the first plate body 111a is arranged horizontally relative to the shell 1, and the second plate body 111b is arranged vertically relative to the shell 1, which makes the first flange 111 form a shoulder structure outside the shell 1, which can provide mounting space for other components (such as the top plate 14) of the clothes treatment apparatus 100. Correspondingly, the first flange 111 can form a convex rib structure inside the shell 1, and the avoiding groove 431 is preferably arranged on the convex rib structure to effectively avoid the second additional part 32. Of course, it can be understood that the avoiding groove 431 on the first flange 111 can also be arranged on the first plate body 111a or the second plate body 111b alone, and those skilled in the art can make reasonable adjustments according to the actual arrangement position of the second additional part 32.

[0090] In some embodiments, the gap is between the relief groove 431 on the first flange 111 and the second additional component 32. Such an arrangement enables the relief groove 431 to provide sufficient relief space for the second additional component 32, avoiding the second additional component 32 from wearing the inner wall surface of the housing 1, and improving the service life of the laundry treating apparatus 100.

[0091] The relief concept of the present application is explained in detail by taking the fourth relief portion 44 provided on the housing 1 as an example.

[0092] In some embodiments, the first drum assembly 2 comprises a first drum 21, and the second drum assembly 3 comprises a second drum 31. The housing 1 has a first opening 16 opposite to the first drum 21 and a second opening 17 opposite to the second drum 31. The laundry treating apparatus 100 further comprises a first switch door assembly 7 for opening or closing the first opening 16 and a second switch door assembly 8 for opening or closing the second opening 17. The first switch door assembly 7 and the second switch door assembly 8 each comprise a door body 91 and a connecting structure 92. The door body 91 is connected to the housing 1 through the connecting structure 92. The relief portion 4 comprises a fourth relief portion 44 provided on the housing 1. The fourth relief portion 44 is used to relieve the connecting structure 92 of the first switch door assembly 7 and / or the connecting structure 92 of the second switch door assembly 8.

[0093] In use, the operator can open the door body 91 of the corresponding switch door assembly to open the corresponding opening of the corresponding drum, and place the laundry in the corresponding drum. Then, the door body 91 is closed to close the corresponding opening, so that the laundry is further treated in the corresponding drum. In assembly, the connecting structure 92 is connected to the housing 1, and the door body 91 is connected to the connecting structure 92, so that the door body 91 can open or close the corresponding opening through the connecting structure 92. In the technical solution provided by the present disclosure, the fourth relief portion 44 provided on the housing 1 can realize convenient assembly between the door body 91 of the corresponding switch door assembly and the housing 1 through the connecting structure 92. In addition, by providing the fourth relief portion 44, the use space inside the laundry treating apparatus 100 can be expanded, so as to improve the utilization rate. In addition, the fourth relief portion 44 effectively avoids friction between the connecting structure 92 and the housing 1 under long-term use, thereby improving the service life of the laundry treating apparatus 100. Furthermore, when the door body 91 continuously opens or closes the corresponding opening of the housing 1 through the connecting structure 92, the fourth relief portion 44 provided on the housing 1 for the connecting structure 92 can avoid abnormal noise of the laundry treating apparatus 100.

[0094] In some embodiments, the connecting structure 92 of the first switch door assembly 7 is located on the side of the first central axis away from the second central axis in the horizontal direction. And / or, the connecting structure 92 of the second switch door assembly 8 is located on the side of the second central axis away from the first central axis in the horizontal direction. Such an arrangement enables the connecting structure 92 of the first switch door assembly 7 and the connecting structure 92 of the second switch door assembly 8 to be arranged away from each other in the horizontal direction, and thus enables the door body 91 of the first switch door assembly 7 and the door body 91 of the second switch door assembly 8 to not interfere with each other when opening or closing the first opening 16 and the second opening 17, and to reliably achieve independent opening or closing, avoiding the problem of damage caused by the door body 91 of the first switch door assembly 7 and the door body 91 of the second switch door assembly 8 opening or closing in the same direction, and improving the service life of the clothes treatment apparatus 100 and the user's experience.

[0095] In some embodiments, as shown in FIG. 16, the fourth avoiding portion 44 includes an avoiding gap 441, which is located on the side of the second cylinder 31 away from the first cylinder 21 in the horizontal direction, and the extending length of the avoiding gap 441 in the height direction of the housing 1 is greater than the outer diameter of the second cylinder 31. Considering the arrangement position of the second cylinder 31 and the non-interference opening or closing manner of the door body 91 of the first switch door assembly 7 and the door body 91 of the second switch door assembly 8, the avoiding gap 441 is arranged on the side of the second cylinder 31 away from the first cylinder 21 in the horizontal direction, which can facilitate the assembly of the door body 91 of the second switch door assembly 8, improve the use reliability of the door body 91 of the second switch door assembly 8, and also be beneficial to the structural arrangement rationality of the clothes treatment apparatus 100.

[0096] In some embodiments, as shown in FIG. 16, the extending length of the avoiding gap 441 in the height direction of the housing 1 is greater than the outer diameter of the second cylinder 31. Such an arrangement enables the avoiding gap 441 to effectively avoid the second switch door assembly 8 and the second cylinder 31, and provides sufficient avoiding space.

[0097] In some embodiments, as shown in FIG. 16, in the height direction, the horizontal plane where the center of the connecting structure 92 of the second switch door assembly 8 is located coincides with the horizontal plane where the center of the avoiding gap 441 is located. Such an arrangement enables the connecting structure 92 of the second switch door assembly 8 to be located at the center position of the avoiding gap 441, i.e., the avoiding space of the two ends of the connecting structure 92 of the second switch door assembly 8 is the same as that of the two ends of the avoiding gap 441, improving the reliability of avoiding. And such an arrangement is also obviously beneficial to the disassembly of the connecting structure 92, etc.

[0098] In some embodiments, as shown in FIGS. 10, 11, 12 and 13, the shell 1 comprises a front plate 11, a rear plate 12, two side plates 13 connected between the front plate 11 and the rear plate 12, and a top plate 14 and a bottom plate 15 connected between the front plate 11 and the rear plate 12, the front plate 11 is provided with an opening, and the fourth avoiding portion 44 is arranged on at least one of the front plate 11, the side plate 13, the top plate 14 and the bottom plate 15. It should be noted that the technical solution of the present disclosure is only taken as an example that the opening is arranged on the front plate 11, and accordingly, the switch door assembly is also arranged on the front plate 11. Such an arrangement is convenient for the user to use the laundry treatment equipment 100, and is also more in line with the current use habit of the laundry treatment equipment 100. However, it should be understood that the fourth avoiding portion 44 can also be arranged on at least one of the side plate 13, the top plate 14 and the bottom plate 15, so as to avoid the connecting structure 92 of the corresponding switch door assembly. In addition, arranging the corresponding avoiding portion 4 on the side wall, the top plate 14 and the bottom plate 15 other than the front plate 11 can also achieve the purpose of avoiding other component structures of the laundry treatment equipment 100 arranged in the shell 1, thereby improving the use applicability and reliability of the shell 1.

[0099] In some embodiments, as shown in FIG. 16, the front plate 11 has a second flange 112, and the fourth avoiding portion 44 comprises an avoiding gap 441 arranged on the second flange 112, and the avoiding gap 441 is used for avoiding the connecting structure 92 of the second switch door assembly 8. The fourth avoiding portion 44 is arranged on the second flange 112. Exemplarily, the second flange 112 can be arranged on the side of the front plate 11, so as to be connected to the side plate 13. The arrangement of the second flange 112 facilitates the connection between the front plate 11 and the side plate 13, and at the same time, the second flange 112 can also increase the connection area between the front plate 11 and the side plate 13, thereby improving the connection reliability. Arranging the fourth avoiding portion 44 on the second flange 112 is reasonable, and at the same time, forming the fourth avoiding portion 44 on the second flange 112 is also conducive to simplifying the forming process of the fourth avoiding portion 44. In addition, according to the position of the connecting structure 92, the second flange 112 can also be arranged on the top of the front plate 11, so as to be connected to the top plate 14, or can be arranged on the bottom of the front plate 11, so as to be connected to the bottom plate 15, and the present disclosure is not limited thereto.

[0100] In some embodiments, the second flange 112 can include a third plate body 112a extending from the front plate 11 towards the side plate 13, and a fourth plate body 112b extending from the third plate body 112a towards the inside of the shell 1. The third plate body 112a is connected to the side plate 13. The fourth avoiding portion 44 can include an avoiding notch 441 provided on the fourth plate body 112b. The avoiding notch 441 forms an avoiding space. The fourth plate body 112b extends from the third plate body 112a towards the inside of the shell 1, i.e. the fourth plate body 112b extends towards the side close to the second cylinder 31 and the second switch door assembly 8, and the avoiding notch 441 is provided on the fourth plate body 112b, which can effectively achieve the avoiding purpose of the second cylinder 31 and the second switch door assembly 8, and improve the avoiding reliability.

[0101] In some embodiments, the avoiding notch 441 can be a U-shaped groove. Of course, it can be understood that the avoiding notch 441 can also be various other forms, which are not limited herein, and can be adjusted by those skilled in the art according to actual conditions. In the embodiments of the present disclosure, the avoiding notch 441 is designed as a U-shaped groove, which is simple and convenient to form, and can effectively avoid the connection structure 92 through the groove bottom, thereby improving the avoiding reliability. Further, the corners of the U-shaped groove and the two ends of the opening side of the U-shaped groove are provided with transition fillets. The transition fillets can avoid the corners of the U-shaped groove and the two ends of the opening side causing damage to the connection structure 92 and other components in the clothes processing equipment 100, thereby improving the use safety of the clothes processing equipment 100. In addition, the arrangement of the avoiding notch 441 can also facilitate the demolding of the front plate 11 and / or the second flange 112. It can be understood that the second flange 112 can be integrally formed on the front plate 11, or can be detachably connected with the front plate 11, which is not limited in the present disclosure.

[0102] In some embodiments, the connection structure 92 mentioned above can be a hinge. In the embodiments of the present disclosure, the hinge is used as the connection structure 92 mainly because of its advantages of convenient installation, low cost, reliable use, etc. Of course, it can be understood that the connection structure 92 can also be any other suitable form, for example, the door body 91 is designed as a folding door, and the connection structure 92 is designed as a connection protrusion with a sliding groove. The folding door is located in the sliding groove of the connection protrusion and can be folded or opened in the sliding groove, thereby achieving the opening and closing purposes of the opening. The specific implementation of the connection structure 92 is not limited herein, as long as the purpose of connecting the door body 91 to the shell 1 through the connection structure 92 can be achieved, and those skilled in the art can replace and select according to actual conditions.

[0103] In some embodiments, as shown in FIGS. 2, 3, 4 and 5, the laundry treating apparatus 100 further comprises a first side beam 101 and a second side beam 102. The first side beam 101 and the second side beam 102 have an avoiding gap 105 therebetween. The second drum assembly 3 comprises a second drum 31 and a second additional member 32 connected to the second drum 31. Part of the second drum 31 and / or at least part of the second additional member 32 is located in the avoiding gap 105. By the above technical solution, by providing the first side beam 101 for connecting the first drum 21 and the second side beam 102 for connecting the second drum 31 in the housing 1, the first drum 21 and the second drum 31 are fixed in the housing 1, and by the avoiding gap 105 between the first side beam 101 and the second side beam 102, at least part of the second additional member 32 located on the second drum 31 and / or part of the second drum 31 can be avoided, so that the second drum 31 can be avoided from colliding with the housing 1 or the first side beam 101 or the second side beam 102 when washing and vibrating, and the safety and reliability of the laundry treating apparatus 100 are improved.

[0104] In addition, by providing the avoiding gap 105 between the first side beam 101 and the second side beam 102, the space inside the housing 1 can be fully utilized, and the space utilization rate is improved, which is particularly obvious for the double drum washing machine with compact layout.
