DETAILED DESCRIPTION

[0075] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0076] In the present disclosure, unless otherwise stated, the orientation words such as "upper, lower, front, back, left, right" can refer to the orientation of the figures shown in FIG. 1 and FIG. 2, wherein, during normal use of the laundry treating apparatus, the upper and lower directions can be parallel to the vertical plane, the left and right directions and the front and back directions can be parallel to the horizontal plane, and "inner, outer" refers to "inner, outer" with respect to the outline of the corresponding component itself. In addition, the terms "first", "second", and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequential or important meanings. Furthermore, in the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements, unless otherwise explained. The above definitions are only for the explanation and illustration of the present disclosure, and should not be understood as a limitation of the present disclosure.

[0077] The laundry treating apparatus in the exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0078] The inventor has found that, in the related art, the two independent washing drums of the double-drum washing machine are arranged in the vertical direction with a large volume. If the size of the double-drum laundry treating apparatus is reduced, for example, by placing the double-drum laundry treating apparatus into the size of a conventional single-drum laundry treating apparatus, the size of the two drums needs to be reduced, and if the size of the drum is too small, the use requirements cannot be met.

[0079] To solve the above technical problem, with reference to FIG. 1 to FIG. 37, the present disclosure provides a laundry treating apparatus 1000, comprising a housing 1, a first drum assembly 2 and a second drum assembly 3, wherein the first drum assembly 2 is arranged in the housing 1 and comprises a first drum 21, the second drum assembly 3 is arranged in the housing 1 and comprises a second drum 31, a first central axis of the first drum 21 is arranged in parallel with a second central axis of the second drum 31, and the second central axis is located above the first central axis on one side.

[0080] By the above technical solution, taking the second drum 31 relative to the first drum 21 as an example, the larger space above the left or right of the first drum 21 can be used to arrange the second drum 31, and at the same time, the first drum 21 can be moved downward to reduce the size between the first drum 21 and the bottom plate 11 of the housing 1, thereby ensuring that the first drum 21 and the second drum 31 still have relatively large sizes when the size of the housing 1 of the laundry treating apparatus 1000 is compressed. In other words, the concept of offsetting the second drum 31 relative to the first drum 21 in the vertical direction can make the size of the housing 1 as small as possible, thereby at least reducing the space occupied by the laundry treating apparatus 1000 in the vertical direction, so as to make the space utilization of the laundry treating apparatus 1000 more reasonable and improve the overall integration.

[0081] The first drum 21 and the second drum 31 can be projected on a vertical plane and / or a horizontal plane to at least partially coincide, so that the size of the first drum 21 and the second drum 31 can be further expanded under the condition that the size of the housing 1 is limited, or the housing 1 can be made as small as possible under the condition that the first drum 21 and the second drum 31 have relatively large sizes.

[0082] In consideration of the laundry processing capacity, the laundry processing scenario, and the structural size of the laundry processing apparatus 1000, the above arrangement can reasonably realize the position arrangement of the first drum 21 and the second drum 31. Alternatively, the size of the first drum 21 is larger than that of the second drum 31, that is, the second drum 31 can be arranged above the side of the first drum 21 without increasing the structural size of the laundry processing apparatus 1000, effectively utilizing the idle space of the laundry processing apparatus 1000, thereby increasing the laundry processing capacity of the laundry processing apparatus 1000 and enabling the laundry processing apparatus 1000 to be applicable to different laundry processing scenarios, improving the user experience.

[0083] In an exemplary application scenario, referring to FIGS. 1 and 2, the laundry processing apparatus 1000 can be a washing machine. Exemplarily, the first drum 21 and the second drum 31 can both be configured as washing drums. In this way, that is, in the offset manner of the second drum 31 relative to the first drum 21, the size (e.g., the outer diameter) of the second drum 31 can be expanded, thereby expanding the volume of the second drum 31 to improve the washing or drying capacity. Under this arrangement of the first drum 21 and the second drum 31, the second drum 31 is above the side of the first drum 21. The first drum 21 is below the side of the second drum 31 and has a larger internal space for washing a larger number of clothes or a larger single piece of clothes, and the second drum 31 is above the side of the first drum 21 and has a smaller internal space for washing a smaller number of clothes or a smaller single piece of clothes. Thus, by arranging the first drum 21 and the second drum 31, classified washing of clothes can be realized, and the volume of the second drum 31 is small to reduce the size of the laundry processing apparatus 1000 in the up-down direction and maintain or reduce the size of the laundry processing apparatus 1000 in the left-right direction, thereby reducing the space occupation and reasonably utilizing the space.

[0084] It should be noted that the sizes of the first drum 21 and the second drum 31 can also be the same, 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 used to deal with different clothes processing situations. For example, the first drum 21 and the second drum 31 can be used to deal with clothes that are prone to color mixing, such as dark or light clothes, to avoid dyeing problems during clothes processing and improve user experience. Alternatively, the first drum 21 and the second drum 31 can be used to deal with clothes of different materials to set the corresponding cleaning strength and cleaning time separately. The above different clothes processing situations 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 situation, and the present disclosure does not make specific limitations thereto.

[0085] In addition, in order to adapt the first drum 21 and the second drum 31 to the mounting space of the shell 1, the distance between the first central axis of the first drum 21 and the second central axis of the second drum 31 can be 355mm-404mm, further, the distance between the first central axis of the first drum 21 and the second central axis of the second drum 31 can be 367mm-394mm, and further the distance between the first central axis of the first drum 21 and the second central axis of the second drum 31 can be 367mm-377mm.

[0086] It should be noted that the laundry treating apparatus 1000 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 drum 21 and the second drum 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 washing machine, 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 drum 21 and the second drum 31 can be different, for example, the outer diameter of the first drum 21 is greater than that of the second drum 31, and the ratio of the outer diameter of the first drum 21 to that of the second drum 31 is 2.8-3.1. For example, the outer diameter of the first drum 21 can be 530mm-543mm, and the outer diameter of the second drum 31 can be 175mm-185mm, so that the washing objects can be distinguished by the two drums with different sizes. The outer diameter of the first drum 21 can be the outer diameter of the first outer drum 212 in the first drum 21, and the outer diameter of the second drum 31 can be the outer diameter of the second outer drum 312 in the second drum 31. In addition, the first drum 21 further includes the first inner drum 211 for washing or drying clothes, etc., and the second drum 31 further includes the second inner drum 311 for washing or drying clothes, etc. Of course, the double-barreled washer-dryer provided in the present embodiment includes the components necessary for the double-barreled washer-dryer in addition to the housing 1, the first drum assembly 2 and the second drum 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.

[0087] Based on the overall inventive concept, i.e., integrating the two drum bodies of the double-drum laundry treating apparatus 1000 in the housing of the approximate size of a single-drum laundry treating apparatus, the present disclosure can be improved as described below to enable the double drum bodies to maintain a large size (laundry treating capacity), to enable the apparatus to have more perfect functions, and to enable the apparatus to operate more stably even when the double drum bodies are arranged in the housing of the approximate size of a single-drum laundry treating apparatus. These improvements include, but are not limited to, the following: a clearance design between the drum body assemblies and each other and between the drum body assemblies and the housing (e.g., to avoid frictional collision and to enable expansion of the internal use space, etc.), a spatial position design of the drum body assemblies and each additional member (e.g., to utilize the layout of the space to improve the space utilization, the stable operation of the apparatus, etc.), an optimized design for system vibration (e.g., to improve the vibration of the second drum body 31 and to enhance the stability thereof, etc.), an optimized design for system operation (e.g., to optimize the functions of drying, condensing, draining, water supply, steam exhaust, and bubble elimination, etc.), a wiring design of system pipelines (e.g., to optimize the routing of the pipelines for a compact layout, etc.), an integrated design of each additional member (e.g., to improve the integration and the space utilization, etc.), a protection design of each additional member (e.g., to protect the internal condensate water, to optimize the exhaust of the apparatus air outlet, etc.), and a significant optimization of the overall scheme of the combination of the above-mentioned improvements.

[0088] For example, based on the overall inventive concept, a clearance design can be performed between the drum body assemblies and each other, between the drum body assemblies and the housing or other components, to avoid problems such as friction, collision, interference, etc., and to expand the internal use space and improve the space utilization.

[0089] For example, in some embodiments, referring to FIGS. 3a to 7, at least one of the housing 1, the first drum body assembly 2, and the second drum body assembly 3 can be provided with a clearance portion 9 for clearing at least one of the housing 1, the first drum body assembly 2, and the second drum body assembly 3. The clearance portion 9 can avoid collision between the first drum body assembly 2 and the second drum body assembly 3, and can also avoid collision between the first drum body assembly 2 and / or the second drum body assembly 3 and the housing 1, thereby improving the safety and reliability of the laundry treating apparatus 1000. For example, when the clearance portion 9 is provided on the housing 1, at least one of the first drum body assembly 2 and the second drum body assembly 3 can be cleared. When the clearance portion 9 is provided on the first drum body assembly 2, the second drum body assembly 3 or the housing 1 can be cleared. When the clearance portion 9 is provided on the second drum body assembly 3, the first drum body assembly 2 or the housing 1 can be cleared.

[0090] In some embodiments, at least one of the first drum 21 and the second drum 31 is provided with the avoiding portion 9 for avoiding the other, so that when the laundry treating apparatus 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 9, thereby improving the safety and stability of the laundry treating apparatus.

[0091] In order to avoid the collision between the first drum 21 and the second drum 31 during the washing process, in some embodiments, the minimum distance between the avoiding portion 9 on the first drum 21 and the second drum 31 and / or the avoiding portion 9 on the second drum 31 is greater than a preset distance; and / or, the minimum distance between the avoiding portion 9 on the second drum 31 and the first drum 21 and / or the avoiding portion 9 on the first drum 21 is greater than a preset distance. Exemplarily, the first drum 21 and the second drum 31 are both provided with the avoiding portion 9, the avoiding portion 9 on the first drum 21 and the avoiding portion 9 on the second drum 31 can be oppositely arranged or arranged in a circumferential direction or in an axial direction, and the minimum distance between the avoiding portion 9 on the first drum 21 and the avoiding portion 9 on the second drum 31 is greater than a preset distance, for example, the preset distance can be 3mm-40mm, thus, by providing the avoiding portion 9 on the first drum 21 and the avoiding portion 9 on the second drum 31 and the minimum distance between the two avoiding portions 9 being greater than a preset distance, the first drum 21 and the second drum 31 can have enough space during the washing process to avoid the collision between the first drum 21 and the second drum 31.

[0092] It can be understood that the above-mentioned embodiment that the minimum distance between the avoiding portion 9 on the first drum 21 and the avoiding portion 9 on the second drum 31 is greater than a preset distance is illustrative, in other embodiments, the avoiding portion 9 on the first drum 21 can be used to avoid the second drum 31, the avoiding portion 9 on the second drum 31 can avoid the first drum 21, the two avoiding portions 9 are used to avoid the first drum 21 and the second drum 31 respectively, and the minimum distance between the avoiding portion 9 on the first drum 21 and the second drum 31 can be greater than a preset distance, the minimum distance between the avoiding portion 9 on the second drum 31 and the first drum 21 can be greater than a preset distance, in this way, the first drum 21 and the second drum 31 can have enough space during the washing process to avoid the collision between the first drum 21 and the second drum 31.

[0093] In addition, the preset distance can be optimized according to the size and mounting position of the shell 1, the first cylinder 21 and the second cylinder 31. For example, in the embodiment, the preset distance is preferably 15-31 mm, and further, the preset distance can be 25 mm. In this way, the range of the preset distance is selected according to the specific working condition, so that the first cylinder 21 and the second cylinder 31 have enough space during washing, and the first cylinder 21 and the second cylinder 31 are prevented from colliding.

[0094] The selected position of the avoiding part 9 can be set according to the following manner. For example, when the avoiding part 9 is not provided on the first cylinder 21 and / or the second cylinder 31, the distance between the two closest points of the first cylinder 21 and the second cylinder 31 is less than the preset distance 25 mm, and the avoiding part 9 is provided at the position of at least one of the two points. For example, the avoiding part 9 can be provided on the first cylinder 21 at the closest point between the first cylinder 21 and the second cylinder 31. In this way, the distance between the first cylinder 21 and the second cylinder 31 is increased at the position by providing the avoiding part, so that the first cylinder 21 and the second cylinder 31 are prevented from colliding due to vibration during washing, and the reliability of the clothes treatment apparatus is improved.

[0095] In addition, for example, before the avoiding part 9 is provided, the avoiding part 9 is provided at at least one of the two closest positions of the first cylinder 21 and the second cylinder 31 to increase the distance between the two closest positions to prevent collision. It can be understood that after the avoiding part 9 is provided, the distance between the two positions can still be the minimum distance between the first cylinder 21 and the second cylinder 31. In addition, in addition to the avoiding part 9 provided at at least one of the two positions, it is obvious that another avoiding part 9 can be provided at another position, which is not limited in the disclosure.

[0096] In some embodiments, the front of the first drum 21 is provided with a first opening door assembly for loading laundry into the first drum 21, and the rear of the first drum 21 is provided with a first driving motor for driving the first inner drum of the first drum 21 to rotate. The front of the second drum 31 is also provided with a second opening door assembly for loading laundry into the second drum 31, and the rear of the second drum 31 is provided with a second driving motor for driving the second inner drum of the second drum 31 to rotate. In this way, the front of the first drum 21 and the front of the second drum 31 have a large vibration amplitude and are more likely to collide during the washing process. Therefore, in some embodiments, the first drum 21 and the second drum 31 are each provided with a relief portion 9. The distance between the relief portion 9 on the first drum 21 and the front end of the first drum 21 is less than the distance between the relief portion 9 on the first drum 21 and the rear end of the first drum 21. And / or, the distance between the relief portion 9 on the second drum 31 and the front end of the second drum 31 is less than the distance between the relief portion 9 on the second drum 31 and the rear end of the second drum 31.

[0097] When the front ends of the first drum 21 and the second drum 31 need to be relieved, the relief portion 9 on the first drum 21 is at least partially located at the front end of the first drum 21. And / or, the relief portion 9 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 9 on the second drum 31 is at least partially located in front of the relief portion 9 on the first drum 21. Therefore, 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 9 on the second drum 31 to be at least partially in front of the relief portion 9 on the first drum 21, more 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 the washing process, thereby improving the reliability of the laundry treatment apparatus.

[0098] It can be understood that the relief portion 9 can be constructed in any suitable manner. For example, the relief portion 9 can include a relief groove provided on the side wall of the first outer drum 212 of the first drum 21, which can avoid the second outer drum 312 of the second drum 31. Therefore, by providing the relief groove, the possibility of collision between the first drum 21 and the second drum 31 due to vibration during the washing process can be reduced, thereby improving the reliability of the laundry treatment apparatus 1000.

[0099] In some embodiments, referring to FIG. 3a, the avoiding part 9 can include a third avoiding part 91, and the third avoiding part 91 can include a third avoiding groove 911, which is arranged on the first outer cylinder 212 of the first cylinder body 21. The first outer cylinder 212 includes an outer circumferential surface and a front end surface. The third avoiding groove 911 is arranged at the junction of the outer circumferential surface and the front end surface, and is located above the horizontal plane of the first central axis of the first cylinder body 21 and on the side of the vertical plane of the first central axis of the first cylinder body 21 facing the second cylinder body 31. Thus, the third avoiding groove 911 arranged on the first cylinder body 21 can form an avoiding space with the second cylinder body 31 to avoid collision between the first cylinder body 21 and the second cylinder body 31 during washing, thereby improving the reliability of the clothes treatment apparatus 1000.

[0100] Referring to FIG. 3a, the third avoiding part 91 can further include a fourth avoiding groove 92, which is arranged on the front end surface of the first outer cylinder 212 of the first cylinder body 21. The front end surface of the first outer cylinder 212 is provided with a reinforcing rib for reinforcing the end structural strength of the first outer cylinder 212. Part of the reinforcing rib is recessed toward the first central axis of the first cylinder body 21 to form the fourth avoiding groove 92. The fourth avoiding groove 92 is located above the horizontal plane of the first central axis of the first cylinder body 21 and on the side of the vertical plane of the first central axis of the first cylinder body 21 facing the second cylinder body 31. The arrangement of the fourth avoiding groove 92 can avoid collision between the first cylinder body 21 and the second cylinder body 31 due to vibration during washing, thereby improving the reliability of the clothes treatment apparatus 1000.

[0101] In some embodiments, referring to FIGS. 2 to 4, the second cylinder body 31 includes a second outer cylinder 312, a connecting part 313, and a cylinder ring 36. The connecting part 313 is connected to the second outer cylinder 312 and protrudes outward from the outer side wall of the second outer cylinder 312. The avoiding part 9 is arranged on at least one of the first outer cylinder 212, the connecting part 313, and the cylinder ring 36. Thus, the arrangement of the avoiding part 9 on at least one of the first outer cylinder 212, the connecting part 313, and the cylinder ring 36 can avoid collision between the first cylinder body 21 and the second cylinder body 31 due to vibration during washing, thereby improving the reliability of the clothes treatment apparatus.

[0102] In some possible implementation manners, referring to FIG. 4, the avoiding part 9 further includes a fifth avoiding slot 95 arranged on the connecting part 313, the second outer cylinder 312 is provided with an annular protrusion 314 extending radially outward, the connecting part 313 is arranged on the annular protrusion 314, the connecting part 313 and the cylinder ring 36 are at least partially located in front of the first cylinder body 21 in the front-rear direction, the connecting part 313 is provided in a plurality of numbers and is arranged in a circumferential direction of the central axis of the second cylinder body 31, the middle part of the connecting part 313 is provided with a mounting hole, the cylinder ring 36 can be a substantially circular ring, the cylinder ring 36 is provided with a matching hole matched with the connecting part 313, and a fastener passes through the opposite mounting hole and the matching hole to fix the cylinder ring 36 and the connecting part 313, so as to fix the cylinder ring 36 on the second outer cylinder 312, and the fifth avoiding slot 95 arranged on the connecting part 313 can avoid the annular protrusion 314 from colliding with the first cylinder body 21, thereby improving the reliability of the clothes treatment apparatus.

[0103] In addition, the avoiding part 9 further includes a sixth avoiding slot 96 arranged on the annular protrusion 314, and the sixth avoiding slot 96 is arranged, for example, at the junction of the outer peripheral wall and the side wall of the annular protrusion 314, and the fifth avoiding slot 95 and the sixth avoiding slot 96 are arranged in a circumferential direction and an axial direction of the second cylinder body 31. In this way, by arranging the sixth avoiding slot 96, the first cylinder body 21 and the second cylinder body 31 can be prevented from colliding during washing on the basis of the first avoiding slot 931, the second avoiding slot 932 and the fifth avoiding slot 95, thereby improving the reliability of the clothes treatment apparatus.

[0104] In some embodiments, referring to FIGS. 6, 7 and 11, the avoiding part 9 can include a first avoiding part 93 arranged on the housing 1. The second cylinder assembly 3 further includes a second additional part 32 connected to the second cylinder body 31. The first avoiding part 93 is used to avoid the second additional part 32 and / or the second cylinder body 31. The first avoiding part 93 arranged on the housing 1 can effectively avoid the second additional part 32 arranged inside the housing 1, and provide sufficient vibration space for the vibration of the second cylinder body 31 during the treatment of clothes, thereby avoiding the second additional part 32 from rubbing or colliding with the inner wall of the housing 1 when the second cylinder body 31 vibrates, and affecting the service life of the clothes treatment apparatus 1000, and also avoiding the clothes treatment apparatus 1000 from producing abnormal sound, and optimizing the user experience.

[0105] In some embodiments, referring to FIGS. 1-10, the shell 1 includes a front plate 14, a rear plate 13, two side plates 15 connected between the front plate 14 and the rear plate 13, and a top plate 16 and a bottom plate 11 connected between the front plate 14 and the rear plate 13. The first avoiding portion 93 is arranged on at least one of the front plate 14, the side plate 15, and the top plate 16. It should be noted that the first avoiding portion 93 is only taken as an example of being arranged on the front plate 14 in the technical solution of the present disclosure. However, it should be understood that the first avoiding portion 93 can also be arranged on at least one of the side plate 15 and the top plate 16 for avoiding the second accessory 32. In addition, arranging the corresponding avoiding portion 9 on the side plate 15, the top plate 16, and the bottom plate 11 other than the front plate 14 can also achieve the avoiding purpose for other component structures of the clothes processing equipment 1000 arranged in the shell 1, thereby improving the use applicability and reliability of the shell 1.

[0106] In some embodiments, referring to FIG. 7, the front plate 14 has a first flange 141 connected to the top plate 16. The first flange 141 is arranged to facilitate the connection between the front plate 14 and the top plate 16, and the first flange 141 can also increase the connection area between the front plate 14 and the top plate 16, thereby improving the connection reliability. The first avoiding portion 93 includes an avoiding groove arranged on the first flange 141. Arranging the first avoiding portion 93 on the first flange 141 is reasonable, and forming the avoiding portion 9 on the first flange 141 is also conducive to simplifying the forming process of the avoiding portion 9. The second accessory 32 can include at least one of a water supply flow path, a drying flow path, a steam exhaust flow path, and a water exhaust flow path, and part of the second accessory 32 is located in the avoiding groove.

[0107] In some embodiments, referring to FIG. 7, the avoiding groove on the first flange 141 can include a first avoiding groove 931. The second accessory 32 can include a water supply flow path communicated with the inside of the second cylinder 31. Part of the water supply flow path is located in the first avoiding groove 931. And / or, the avoiding groove on the first flange 141 can include a second avoiding groove 932. The second accessory 32 can include a drying flow path communicated with the inside of the second cylinder 31. Part of the drying flow path is located in the second avoiding groove 932. Such an arrangement can specifically achieve the avoiding purpose for the corresponding second accessory 32 without increasing the complexity of the forming process of the avoiding groove, thereby reducing the manufacturing cost of the clothes processing equipment 1000. At the same time, specifically avoiding the second accessory 32 can also avoid the problem of reducing the structural strength of the shell 1 caused by opening a large area of avoiding portion in the shell 1.

[0108] In some embodiments, referring to FIG. 3b, the avoiding part 9 further comprises a seventh avoiding groove 97 arranged on the top of the second cylinder 31, which can be used for avoiding the shell 1 or for avoiding the second additional part 32, and in the embodiments provided in the present disclosure, the seventh avoiding groove can be used for avoiding the water supply flow path mentioned above, such as the second water pipe 46 below.

[0109] In some embodiments, the shell 1 has a first opening opposite to the first cylinder 21 and a second opening opposite to the second cylinder 31, and the clothes treatment apparatus 1000 further comprises a first switch door assembly for opening or closing the first opening and a second switch door assembly for opening or closing the second opening, both of which comprise a door body and a connecting structure, the door body being connected to the shell 1 through the connecting structure, and the avoiding part 9 comprises a second avoiding part 94 arranged on the shell 1, which is used for avoiding the connecting structure of the first switch door assembly and / or the connecting structure of the second switch door assembly.

[0110] In use, the operator can open the door body of the corresponding switch door assembly to open the corresponding opening of the corresponding cylinder, and place the clothes in the corresponding cylinder. Then the door body is closed to close the corresponding opening, so that the clothes can be further treated in the corresponding cylinder. In assembly, the connecting structure is connected to the shell 1, and the door body is connected to the connecting structure, so that the door body can open or close the corresponding opening through the connecting structure. In the technical solution provided in the present disclosure, the second avoiding part 94 arranged on the shell 1 can realize the convenient assembly between the door body of the corresponding switch door assembly and the shell 1 through the connecting structure. In addition, by arranging the second avoiding part 94, the use space inside the clothes treatment apparatus 1000 can be expanded to improve the utilization rate. In addition, the second avoiding part 94 effectively avoids the friction between the connecting structure and the shell 1 after long-term use, thereby improving the service life of the clothes treatment apparatus 1000. In addition, when the door body constantly opens or closes the corresponding opening of the shell 1 through the connecting structure, the second avoiding part 94 arranged on the shell 1 for the connecting structure can avoid the clothes treatment apparatus 1000 from producing abnormal sound.

[0111] In some embodiments, referring to FIGS. 5-7, the housing 1 is provided with a first annular mounting portion 18 protruding towards the inside of the housing 1, an inner side of the first annular mounting portion 18 forms a first opening 181, the avoiding portion 9 includes a first avoiding gap, a first avoiding space is formed between the first annular mounting portion 18 and the first avoiding gap, the connecting structure of the first switch door assembly is connected to the first annular mounting portion 18 and partially located in the first avoiding space, and / or the housing 1 is provided with a second annular mounting portion 19 protruding towards the inside of the housing 1. An inner side of the second annular mounting portion 19 forms a second opening 191, the avoiding portion 9 includes a second avoiding gap 941, a second avoiding space is formed between the second annular mounting portion 19 and the second avoiding gap 941, and the connecting structure of the second switch door assembly is connected to the second annular mounting portion 19 and partially located in the second avoiding space. In this embodiment, the first annular mounting portion 18 and the second annular mounting portion 19 can each be configured as an annular protrusion 861 formed by the front plate 14 recessed towards the inside of the housing 1. The provision of the first annular mounting portion 18 and the second annular mounting portion 19 provides a more reliable mounting position for the switch door assembly, and the recessed annular mounting portion enables the structure of the laundry treatment apparatus 1000 to be more compact and reasonable. In addition, the space formed between the first annular mounting portion 18 and the first avoiding gap for avoiding the connecting structure, and / or the space formed between the second annular mounting portion 19 and the second avoiding gap 941 for avoiding the connecting structure, can be utilized to make the structure more compact and facilitate installation, and also to avoid friction.

[0112] The first annular mounting portion 18 is provided with a first mounting port for mounting the connecting structure of the first switch assembly, and the position of the first mounting port is opposite to the position of the first avoiding gap, and / or the second annular mounting portion 19 is provided with a second mounting port 192 for mounting the connecting structure of the second switch assembly, and the position of the second mounting port 192 is opposite to the position of the second avoiding gap 941. In this way, the position of the first mounting port is opposite to the position of the first avoiding gap, and / or the position of the second mounting port 192 is opposite to the position of the second avoiding gap 941, which facilitates demolding of the first mounting port and / or the second mounting port 192, and provides a convenient condition for the compactness of each component.

[0113] In some embodiments, referring to FIGS. 6 and 7, the front plate 14 has a second flange 142 connected to the side plate 15, and a second avoiding gap 941 is arranged on the second flange 142 for avoiding the connecting structure of the second switch door assembly. The second avoiding portion 94 is arranged on the second flange 142. The arrangement of the second flange 142 facilitates the connection between the front plate 14 and the side plate 15, and the second flange 142 can also increase the connection area between the front plate 14 and the side plate 15, improving the connection reliability. The second avoiding gap 941 is arranged on the second flange 142, which is a reasonable arrangement position, and the formation of the second avoiding portion 94 on the second flange 142 is also conducive to simplifying the forming process of the avoiding portion 9.

[0114] The connecting structure can be a hinge.

[0115] The above exemplary describes the avoiding design of the clothes treatment apparatus 1000 by arranging the avoiding portion 9. In addition to avoiding the collision and friction between components and increasing the layout space by arranging the avoiding portion 9, the space position design between components can also be used to optimize the layout and improve the space utilization, for example, as described below, the first drum 21 can be lowered relative to the clothes treatment apparatus 1000 to increase the internal space above the first drum 21, the position design of the remaining components is optimized by using the increased space, and the size of the second drum 31 can be further increased to enhance the clothes treatment capacity.

[0116] In some embodiments, referring to FIGS. 1 and 2, the housing 1 can include a bottom plate 11, and the distance between the lowest point of the outer peripheral wall of the first drum 21 and the bottom plate 11 can be 50mm-100mm, specifically 60mm, 70mm, 80mm, 90mm, or 95mm. In the working or carrying process of the clothes treatment apparatus 1000, the first drum 21 will vibrate, and when the first drum 21 vibrates to the highest point, the distance between the lowest point of the outer peripheral wall of the first drum 21 and the bottom plate 11 can be 100mm-110mm, specifically 105mm; and when the first drum 21 vibrates to the lowest point, the distance between the lowest point of the outer peripheral wall of the first drum 21 and the bottom plate 11 can be 60mm-80mm, specifically 65mm, 70mm, or 75mm. The distance between the lowest point of the outer peripheral wall of the first drum 21 and the bottom plate 11 when the first drum 21 vibrates to the lowest point will not be lower than the distance between the lowest point of the outer peripheral wall of the first drum 21 and the bottom plate 11 when the first drum 21 is full. Here, the full load of the first drum 21 refers to the working condition that the first drum 21 is full of clothes and water.

[0117] It can be understood that the second cylinder 31 is arranged above and right of the first cylinder 21, in order to increase the space utilization rate inside the laundry treating apparatus 1000, the first cylinder 21 is moved downward so that the distance between the lowest point of the outer peripheral wall of the first cylinder 21 and the bottom plate 11 is arranged in the range of 50mm-100mm, in the case that the installation space of the first cylinder 21 is limited, the installation of the second cylinder 31 can be avoided, and at the same time, sufficient drop allowance can be ensured to avoid collision with the bottom wall of the shell during movement and drop.

[0118] In some embodiments, an electrical element or a dosing box 70 is arranged between the first cylinder 21 and the bottom plate 11 of the shell. In the case that the double cylinder is arranged inside the shell, since the second cylinder 31 is arranged above and right of the first cylinder 21, the electrical element and the dosing box 70 originally arranged above the first cylinder 21 need to be arranged below the first cylinder 21. Specifically, the electrical element can be a water pump or the like. It should be noted that other devices can also be arranged between the first cylinder 21 and the bottom plate 11 of the shell, which are not limited to the electrical element and the dosing box, and can be adjusted according to the actual layout.

[0119] As known from the above, the electrical element and the dosing box 70 are arranged below the first cylinder 21, at this time, the distance between the lowest point of the outer peripheral wall of the first cylinder 21 and the bottom plate 11 needs to be larger to install the electrical element or the dosing box 70 and the like. In order to solve the above technical problem, in the embodiments of the present disclosure, the distance between the lowest point of the outer peripheral wall of the first cylinder 21 and the bottom plate 11 can be 80mm-100mm. In this way, drop allowance can be reserved, and installation space for the electrical element or the dosing box 70 of the first cylinder 21 can be reserved, which facilitates device layout.

[0120] The laundry treating apparatus 1000 can include a damper 20 connected between the lower part of the first cylinder 21 and the bottom plate 11, and extending downwardly and obliquely from the outer peripheral wall of the first cylinder 21 toward the bottom plate 11, which can reduce the vibration of the first cylinder 21 in the up-down direction and the left-right direction under the action of centrifugal force.

[0121] The adjustment length of the damper 20 can be 120mm-190mm to adapt to the downward movement of the first cylinder 21. In the embodiments of the present disclosure, the longest stroke of the damper 20 is 190mm, and the stroke of the damper 20 is 168mm after the first cylinder 21 is installed on the damper 20. In the vibration process of the first cylinder 21, the stroke of the damper 20 can be 120mm at the shortest and 190mm at the longest. The above dimensions can ensure that the damping performance of the damper 20 is good.

[0122] Further, the stroke of the damper 20 can be 138mm-180mm. In the embodiments of the present disclosure, the length of the damper 20 is 138mm when the first cylinder 21 vibrates to the lowest point, and the length of the damper 20 is 180mm when the first cylinder 21 vibrates to the highest point.

[0123] In the related art, the distance between the lowest point of the outer peripheral wall of the washing cylinder and the bottom wall of the shell is 110mm-180mm, so that in the case where the distance is reduced, the angle between the central axis of the damper 20 and the horizontal direction needs to be adjusted to ensure that the damper 20 has a sufficient moving stroke. In the present disclosure, the angle between the central axis of the damper 20 and the horizontal direction is 70°-85°, and specifically can be 75°, 80°. In the related art, the angle between the central axis of the damper rod and the horizontal direction is 65°, and in the embodiments of the present disclosure, in order to reduce the occupied space and improve the integration, the first cylinder 21 can be lowered to facilitate the arrangement of the second cylinder 31 and other components, at this time, by increasing the angle between the central axis of the damper 20 and the horizontal direction, the damper 20 can still have a sufficient adjustable length when the first cylinder 21 is in a lower position, so as to maintain good damping performance.

[0124] In this way, by increasing the angle between the central axis of the damper 20 and the horizontal direction, the damper 20 can still have a sufficient stroke when the first cylinder 21 is in a lower position, and maintain good damping performance. Moreover, the above-mentioned angle is large enough to make the damping effect of the damper 20 on the vibration of the first cylinder 21 in the up-down direction stronger.

[0125] In order to uniformly damp the first cylinder 21, the damper 20 can include a first damper 201 and a second damper 202 respectively arranged on the left and right sides of the first cylinder 21, so that the first cylinder 21 is uniformly stressed as a whole, and the possibility of the first cylinder 21 being offset to one side is reduced. For example, the number of the first dampers 201 can be one, and the number of the second dampers 202 can be two, the first damper 201 is installed at the middle of the outer peripheral wall of the first cylinder 21 in the front-rear direction, and the two second dampers 202 are respectively installed at the two ends of the outer peripheral wall of the first cylinder 21 in the front-rear direction. In this way, the first cylinder 21 is more stable in the front-rear direction and the left-right direction, and the possibility of the first cylinder 21 being offset in the front-rear direction or the left-right direction is reduced.

[0126] In some embodiments, referring to FIG. 2, the two ends of the damper 20 can be respectively hinged with the first cylinder 21 and the bottom plate 11, so that the two ends of the damper 20 can be respectively rotated with the first cylinder 21 and the bottom plate 11, to adapt to the displacement of the first cylinder 21 and the angle change of the damper 20 in the damping process.

[0127] It can be understood that, based on the concept of lowering the first drum 21, the present disclosure can also be further improved in terms of avoiding frictional collision.

[0128] For example, as shown in FIGS. 10 and 11, by lowering the first drum 21, space is reserved above the side of the first drum 21 for arranging the second drum 31, for example, the second drum 31 can be arranged above the right side of the first drum 21. In this way, after the first drum 21 is lowered, the suspension point of the suspension structure 10 for hoisting the first drum 21 also adaptively moves downward away from the top end of the side plate 15, which can cause the angle between the hoisting spring 101 in the suspension structure 10 and the side plate 15 to change (in some embodiments, the angle between the hoisting spring 101 and the side plate 15 can become smaller after being lowered). Thus, the circumference of the hoisting spring 101 can abut against the inner side wall of the side plate 15 and come into contact with and rub against the inner side wall of the side plate 15 during the vibration of the first drum 21. In the present disclosure, in order to prevent the hoisting spring 101 from rubbing against the inner side wall of the side plate 15, the wear-resistant piece 102 is arranged below the fourth side beam 73 to separate the hoisting spring 101 from the side plate 15, so that when the hoisting spring 101 shakes with the vibration of the first drum 21, it can come into direct contact with the wear-resistant piece 102 instead of the side plate 15, thereby avoiding the wear and tear caused by the frictional contact between the hoisting spring 101 and the inner side wall of the side plate 15.

[0129] In some embodiments, referring to FIGS. 2, 10-13, the first drum 21 can be connected to the first side beam 7 and the fourth side beam 73 by the suspension structure 10, and during the operation of the clothes treatment apparatus 1000, the first drum 21 will vibrate to cause the suspension structure 10 to shake, therefore, the clothes treatment apparatus 1000 further comprises the wear-resistant piece 102, which is arranged between the inner side wall of the housing 1 and the suspension structure 10.

[0130] In this way, the contact and friction between the suspension structure 10 and the inner side wall of the housing 1 can be reduced to avoid the wear and tear of the housing 1 or the damage to the suspension structure 10, thereby reducing the wear and tear of the housing 1 and the suspension structure 10 and prolonging the service life of the housing 1 and the suspension structure 10. In addition, the noise caused by the friction between the suspension structure 10 and the inner side wall of the housing 1 can also be reduced.

[0131] For example, the suspension structure 10 comprises the hoisting spring 101, the first drum 21 can be connected to the housing 1 by a plurality of hoisting springs 101, and the number of wear-resistant pieces 102 can be set to be multiple and arranged one-to-one corresponding to the plurality of hoisting springs 101. In this way, in order to replace a single wear-resistant piece 102 in time when it fails, the material of the wear-resistant piece 102 is saved, and the cost is reduced.

[0132] It can be understood that the wear-resistant piece 102 can be configured as a flexible piece, such as a flexible wear-resistant cotton, so that when the wear-resistant piece 102 is in contact with the suspension structure 10, the flexible piece can absorb and disperse the impact force from the suspension structure 10 due to the elasticity of the flexible piece, so as to avoid the wear of the suspension structure 10, and at the same time, reduce the noise generated by the direct friction between the suspension structure 10 and the metal surface of the inner side wall of the shell 1.

[0133] In addition, based on the concept of the downward movement of the first cylinder 21, the present disclosure can be further designed in the aspect of structural reinforcement.

[0134] For example, in some embodiments, referring to FIGS. 2 and 12, the bottom of the shell 1 can be provided with a reinforcing plate 12 for connecting the damper 20, so as to increase the strength and stability of the connection between the damper 20 and the shell 1. The reinforcing plate 12 is provided with a groove 121 for avoiding the first cylinder 21, and the damper 20 is installed on the bottom wall of the groove 121. In this way, the downward movement of the position of the first cylinder 21 can be adapted, and the space utilization of the clothes treatment apparatus 1000 is improved, so as to provide more space for the installation of other components. It can be understood that the groove 121 can also be formed on the bottom plate 11 of the shell 1, which is not specifically limited in the present disclosure.

[0135] Exemplarily, the bottom wall of the groove 121 can be provided with a lug bracket assembly 122 for installing the damper 20. The lug bracket assembly 122 can strengthen the connection strength between the bottom wall of the groove 121 and the damper 20, so as to reduce the possibility of deformation of the bottom wall of the groove 121. It can be understood that the reinforcing plate 12 and the lug bracket assembly 122 can be arranged according to the installation position and the number of the dampers 20. Exemplarily, the present disclosure provides the reinforcing plate 12 on both sides of the first cylinder 21 along the left-right direction, one lug bracket assembly 122 is arranged on the left reinforcing plate 12, and two lug bracket assemblies 122 are arranged on the right reinforcing plate 12, so as to correspond to the installation of the dampers 20.

[0136] Specifically, the lug bracket assembly 122 can include two spaced-apart lug bracket monomers 1221, the lug bracket monomers 1221 are provided with installation holes 1222, the connecting end of the damper 20 is arranged between the two lug bracket monomers 1221, and is connected to the installation holes 1222 through a hinge rod. The end of the damper 20 is provided with a through hole, and the hinge rod sequentially passes through the through hole and the installation holes 1222, so that the lug bracket monomers 1221 and the damper 20 are rotationally connected.

[0137] In addition, based on the above general inventive concept and the concept of the downward movement of the first cylinder 21, the present disclosure can further optimize the layout of various components at the larger space left above or beside the first cylinder 21.

[0138] In some embodiments, referring to FIGS. 8-10, the laundry treating apparatus 1000 further comprises a first side beam 7 and a second side beam 71 connected to the inner wall of the housing 1, and the first side beam 7 and the second side beam 71 have an avoiding gap therebetween, and the second drum assembly 3 further comprises a second additional member 32 connected to the second drum 31, and part of the second drum 31 and / or at least part of the second additional member 32 is located in the avoiding gap. For example, referring to FIG. 9b, the second additional member 32 can be a second exhaust pipe 37 protrudingly arranged on the right side of the second drum 31, and the second exhaust pipe 37 is at least partially located in the avoiding gap.

[0139] In order to reasonably utilize the installation space of the housing 1, in the up-down direction, the central axis of the second drum 31 is located between the first side beam 7 and the second side beam 71, and in the left-right direction, the first side beam 7 and the second side beam 71 are located on the side of the central axis of the second drum 31 away from the central axis of the first drum 21, so that by simultaneously limiting the positional relationship between the second drum 31 and the first side beam 7 and the second side beam 71 in the up-down direction and the left-right direction, the layout between the second drum 31 and the first side beam 7 and the second side beam 71 can be more compact, and the space of the housing 1 can be reasonably utilized.

[0140] In addition, the horizontal plane where the lowest point of the second drum 31 is located is lower than the horizontal plane where the highest point of the first drum 21 is located, and / or in the left-right direction, the distance between the closest point of the second drum 31 to the vertical plane where the central axes of the first drum 21 and the second drum 31 are located and the vertical plane is less than the outer diameter of the first drum 21. In this way, by the first drum 21 and the second drum 31 having partially overlapping regions in the projections in the up-down direction and the left-right direction, the layout of the first drum 21 and the second drum 31 can be more compact, and the size of the first drum 21 and the second drum 31 can be further expanded.

[0141] In this way, by providing the avoiding gap between the first side beam 7 and the second side beam 71, the second additional member 32 located on the second drum 31 can be avoided, so that the second drum 31 can be prevented from colliding with the housing 1 or the first side beam 7 or the second side beam 71 when washing and vibrating, and the safety and reliability of the laundry treating apparatus 1000 are improved. In addition, by providing the avoiding gap between the first side beam 7 and the second side beam 71, the space inside the housing 1 can be fully utilized, and the space utilization rate is improved, which is particularly obvious for a double drum washing machine with a compact layout.

[0142] The projection space formed by the projection path of the first side beam 7 towards the second side beam 71 and / or the projection space formed by the projection path of the second side beam 71 towards the first side beam 7 forms an avoiding space. It can be understood that the projection space formed by the projection path between the first side beam 7 and the second side beam 71 as the avoiding space can make full use of the avoiding space to expand the installation space of the tub and its additional structures, and at the same time, the effective avoiding can be realized.

[0143] In addition, the first dimension of the avoiding space in the direction along the projection path is 122mm, and the second dimension of the avoiding space in the direction perpendicular to the projection path is 16mm-26mm. The first side beam 7 and the second side beam 71 can be located on the side wall of the shell 1, and the second side beam 71 is located above the first side beam 7, so that the first dimension of the avoiding space can also be understood as the height dimension of the avoiding space, and the second dimension of the avoiding space can also be understood as the width dimension of the avoiding space. The present disclosure is not limited thereto, and the first side beam 7 and the second side beam 71 can also be located on the top wall and / or the bottom wall of the shell 1.

[0144] In some embodiments, referring to FIGS. 8 and 9a, the laundry treating apparatus further comprises a third side beam 72 arranged opposite to the second side beam 71 in a horizontal direction, and a support beam 8 connected to the second side beam 71 and the third side beam 72, and the second drum 31 is connected to the support beam 8, the second side beam 71, the third side beam 72 and the support beam 8 can all be configured as steel plates, the first mounting holes can be provided on the second side beam 71 and the third side beam 72, the two ends of the support beam 8 can be provided with first matching holes matched with the first mounting holes, the fasteners pass through the first mounting holes and the first matching holes to fix the support beam 8 between the second side beam 71 and the third side beam 72, the middle part of the support beam 8 close to the second side beam 71 can be provided with a plurality of second mounting holes, the second drum 31 is provided with second matching holes matched with the second mounting holes, and the fasteners pass through the second mounting holes and the second matching holes to fix the second drum 31 on the support beam 8, the horizontal distance between the center axis of the second drum 31 and the second side beam 71 is less than the horizontal distance between the center axis of the second drum 31 and the third side beam 72, so that the second drum 31 can be arranged eccentrically relative to the first drum 21, thereby providing a larger installation space for the second drum 31, so that the first drum 21 and the second drum 31 can be arranged more compactly, the space of the shell 1 can be reasonably utilized, and the size of the first drum 21 and the second drum 31 can be further expanded.

[0145] In order to facilitate the fixed connection of the first side beam 7 and the second side beam 71 with the shell 1, in some implementable manners, the first side beam 7 and / or the second side beam 71 can be detachably fixed to the shell 1, for example, the first side beam 7 and the second side beam 71 are both detachably fixed to the shell 1, wherein a plurality of third mounting holes are arranged on the first side beam 7, a plurality of fourth mounting holes are arranged on the second side beam 71, a plurality of first mounting positions and a plurality of second mounting positions corresponding to the third mounting holes and the fourth mounting holes are arranged on the shell 1, a third matching hole matched with the third mounting hole is arranged on the first mounting position, and a fourth matching hole matched with the fourth mounting hole is arranged on the second mounting position, a fastener passes through the third mounting hole and the third matching hole to fixedly connect the first side beam 7 with the shell 1, and a fastener passes through the fourth mounting hole and the fourth matching hole to fixedly connect the second side beam 71 with the shell 1.

[0146] Of course, the structure that the first side beam 7 and / or the second side beam 71 are detachably fixed to the shell 1 is illustrative, and in other embodiments, the first side beam 7 and / or the second side beam 71 can also be integrally formed on the shell 1.

[0147] It should be noted that the number of the first side beam 7 can be two and arranged opposite in the horizontal direction, the first side beam 7 is provided with a hanging position, and the upper end of the first cylinder body 21 can be connected to the hanging position through a plurality of hanging structures 10, so as to realize the installation of the first cylinder body 21 on the shell 1.

[0148] Based on the concept of the downward movement of the first cylinder body 21 and the position relationship layout of the first cylinder body 21 and the second cylinder body 31, the disclosure can further be designed based on the space between the third side beam 72 and the fourth side beam 73.

[0149] In some embodiments, referring to FIGS. 8 and 9a, the clothes processing apparatus 1000 includes a fourth side beam 73 opposite to the first side beam 7 and a third side beam 72 opposite to the second side beam 71, and the clothes processing apparatus 1000 further includes a first electric control box 6 connected to the fourth side beam 73 and / or the third side beam 72 and surrounding a gap for a pipeline to pass through between the fourth side beam 73 and the third side beam 72. Wherein, the first electric control box 6 can be provided with a main control board (not shown in the figure), and the main control board can be in communication connection with various sensors (not shown in the figure) of the clothes processing apparatus 1000 to receive and analyze signals sent by the sensors, and control the processes of water inlet, cleaning, drainage, drying, etc. of the clothes processing apparatus 1000 according to the analysis results, so as to complete the corresponding processing of the clothes. In addition, the pipeline in the above includes but is not limited to the inlet pipe, the drainage pipe and the power distribution line of the clothes processing apparatus 1000, etc. The end part of the structure member needs to be arranged in different positions of the shell 1 and the main part needs to be arranged in the shell 1.

[0150] It can be understood that when the pipeline passes through the gap, the gap can not only play a role of constraint and limiting of the pipeline to reduce the limiting structure in the shell 1 acting on the pipeline, but also can avoid the pipeline from interfering with the arrangement of other components, so as to facilitate the reasonable layout of other components in the shell 1, thereby improving the space utilization in the shell 1.

[0151] In addition, in order to reduce the possibility of mutual interference between the plurality of pipelines passing through the gap, referring to FIGS. 2 and 13, a pipeline support 30 can be arranged in the gap to provide a wiring space for pipeline installation. Exemplarily, the pipeline support 30 can include a support body 301, a first connecting plate 302 and a second connecting plate 303, the support body 301 can be formed with a pipeline constraint portion 3011, and the first connecting plate 302 and the second connecting plate 303 can be respectively connected to the opposite sides of the support body 301 and bent from the end of the support body 301 towards the same direction, that is, the support body 301 is provided with the pipeline constraint portion 3011 for limiting the position of the pipeline and providing certain support for the pipeline to avoid the pipeline from winding, bending and the like, and the first connecting plate 302 and the second connecting plate 303 are connected to the end of the support body 301 and bent towards the same direction, which can be the direction towards the inner wall of the shell 1, so as to guarantee the aesthetics of the laundry treating apparatus 1000 when the pipeline support 30 is arranged against the shell 1.

[0152] The first connecting plate 302 and the second connecting plate 303 can be detachably connected to the third side beam 72 and the fourth side beam 73 through a clamping structure, so as to fix the support body 301 between the third side beam 72 and the fourth side beam 73, so that the pipeline constraint portion 3011 and the pipeline are fixed between the third side beam 72 and the fourth side beam 73, and the connection between the pipeline support 30 and the third side beam 72 and the fourth side beam 73 is realized through the arrangement of the first connecting plate 302 and the second connecting plate 303 without affecting the pipeline passing through the pipeline constraint portion 3011. At this time, the pipeline is gathered at the pipeline constraint portion 3011, so as to facilitate the connection between the pipeline and the first electric control box 6.

[0153] The pipeline support 30 can also be integrally formed with one of the third side beam 72 and the fourth side beam 73, and detachably connected to the other one of the third side beam 72 and the fourth side beam 73, or the pipeline support 30 can be integrally formed with the third side beam 72 and the fourth side beam 73 at the same time, such as stamping, injection molding or welding, all of which can realize the purpose of connecting the pipeline support 30 between the third side beam 72 and the fourth side beam 73, and the present disclosure does not make specific limitation thereon.

[0154] In further embodiments, referring to FIG. 13, a plurality of partition plates 3012 can be arranged on the bracket body 301 at intervals, and the plurality of partition plates 3012 are arranged at an angle with the bracket body 301, and the partition plates 3012 are used to separate the wiring space into a plurality of wiring channels 304 that are separated from each other. In this way, during the assembly of the clothes treatment apparatus 1000, on the one hand, the arrangement of the plurality of wiring channels 304 enables the pipelines to be evenly distributed within the wiring space, further avoiding the situation that the pipelines are entangled with each other, and on the other hand, the pipelines can pass through any suitable wiring channel 304 according to the different installation positions of the electrical elements that need to be connected within the clothes treatment apparatus, facilitating the arrangement of the pipelines within the clothes treatment apparatus. The number of the partition plates 3012 and the number of the wiring channels 304 separated by the partition plates 3012 can be set to any suitable number according to the number and size of the pipelines, so as to reliably position the pipelines, and the present disclosure does not make specific limitations thereto.

[0155] In addition, a plurality of connection openings 3041 can be arranged on each wiring channel 304, and the connection openings 3041 can face the first control box 6. The pipeline bracket 30 positions the pipelines, that is, the pipelines are gathered at the pipeline bracket 30, and the first control box 6 is usually connected to each electrical element within the shell 1 through various pipelines, and the connection openings 3041 are arranged to face the first control box 6, so as to facilitate the connection between the plurality of pipelines and the first control box 6 in the case that the pipelines are drawn out from the first control box 6 to each electrical element or the pipelines are drawn from each electrical element to the first control box 6.

[0156] In addition, based on the downward movement of the first cylinder 21 and the spatial position relationship between the first cylinder 21 and the second cylinder 31, the space between the two and the shell 1 can be further designed.

[0157] Exemplarily, referring to FIG. 2, the clothes treatment apparatus 1000 can include a control module, which can include the first control box 6 described above, and a second control box 61, a third control box 62 and a fourth control box 63, wherein the first control box 6, the second control box 61, the third control box 62 and the fourth control box 63 can be distributed at different edges inside the shell 1, that is, the first control box 6, the second control box 61, the third control box 62 and the fourth control box 63 are attached to different edges inside the shell 1 to avoid the space in the middle of the shell 1, facilitating the arrangement of the first cylinder 21 and the second cylinder 31, the related drive motors, the pipelines and the drying device and other structures, so as to improve the rationality of the use space of the clothes treatment apparatus 1000.

[0158] The second electric control box 61, the third electric control box 62 and the fourth electric control box 63 can be in communication connection with the main control board in the first electric control box 6 respectively. The main control board can be in communication connection with each sensor in the clothes processing apparatus 1000, and the main control board can receive and analyze signals sent by each sensor, and output signals to the second electric control box 61, the third electric control box 62 and the fourth electric control box 63 according to the analysis results.

[0159] Exemplarily, the second electric control box 61 can be used to control the first drum 21 to rotate, the third electric control box 62 can be used to control the first drum 21 to dry and drain water, and the fourth electric control box 63 can be used to control the second drum 31 to rotate and dry. For example, the second electric control box 61 can be in communication connection with the driving motor of the first drum 21 to control the start and stop of the driving motor of the first drum 21, the third electric control box 62 can be in communication connection with the drying device and the drainage device of the first drum 21 to control the start and stop of the drying device and the drainage device, and the fourth electric control box 63 can be in communication connection with the driving motor and the drying device of the second drum 31 to control the start and stop of the driving motor and the drying device of the second drum.

[0160] Since the second electric control box 61 and the third electric control box 62 are used to control the first drum 21, referring to FIG. 2, the second electric control box 61 and the third electric control box 62 can be arranged at the bottom of the shell 1, and the first electric control box 6 and the fourth electric control box 63 can be arranged at the top of the shell 1, so as to facilitate the wiring between each electric control box and the corresponding drum.

[0161] It can be understood that since the second drum 31 has a small depth, a containing space is arranged between the second drum 31 and the rear wall of the shell 1, and accordingly, the fourth electric control box 63 can be arranged at the rear side edge of the top of the shell 1 and at the rear of the second drum 31, that is, the fourth electric control box 63 can be arranged above the right of the first drum 21 and in the containing space between the second drum 31 and the rear wall of the shell 1. Since the second drum 31 is arranged above the right of the first drum 21, a mounting space is left above the left of the first drum 21, and therefore, the first electric control box 6 can be arranged at the left side edge of the top of the shell 1, that is, the first electric control box 6 can be arranged above the left of the first drum 21.

[0162] In addition, based on the above general inventive concept and the concept that the first drum 21 is moved downward, the space above the first drum 21 can be further optimized in the avoiding design, for example, the layout design of the drying device above the first drum 21 can be improved to reserve more space for the second drum 31, to avoid interference with the second drum 31 and facilitate assembly, etc.

[0163] In some embodiments, referring to FIGS. 2 and 16, the first drum assembly 2 further comprises a first additional component 22, which comprises a first fan 221 arranged on the outer wall of the first drum 21; the top end of the fan shaft c of the first fan 221 is located on the side of the first plane a facing away from the second drum 31; wherein the first plane a is a plane parallel to the up-down direction passing through the central axis of the first drum 21.

[0164] That is, the top end of the fan shaft c of the first fan 221 is located on the side of the first plane a, compared with the axis of the fan in the related art being located on the first plane a, the present disclosure increases the available space on the other side of the first plane a, so as to facilitate the installation of the second drum 31 or other structural components, after the second drum 31 is installed on the other side of the first plane a facing away from the first fan 221, since the gap between them is large enough, no interference will occur between them, ensuring the assembly effect of the clothes treatment equipment 1000 and subsequent use; in addition, such arrangement can also improve the utilization rate of the space in the clothes treatment equipment 1000, and improve the integration of the clothes treatment equipment 1000.

[0165] In some embodiments of the present disclosure, the fan axis passing through the top end of the fan shaft c is located on the lateral side of the first plane a in the left-right direction, or the fan axis intersects the first plane a. According to the different installation positions of the first fan 221, the angle of the fan axis of the first fan 221 may be deflected to a certain extent, for example, when the first fan 221 is arranged in the upper region of the first drum 21, the fan axis passing through the top end of the fan shaft c is parallel to the first plane a, at this time, the distance between the fan axis and the first plane a is the distance between the top end of the fan shaft c and the first plane a; or when the first fan 221 is arranged on the side of the first drum 21, that is, the installation position of the first fan 221 continues to move along the circumferential direction of the first drum 21 from the upper region of the first drum 21, the fan axis passing through the top end of the fan shaft c will be deflected to a certain extent and intersect the first plane a, but as long as the top end of the fan shaft c is still on the lateral side of the first plane a, enough space can be left on the other side of the first plane a to install the second drum 31.

[0166] In addition, the first additional component 22 further comprises a first drying channel 222 connected to the air outlet of the first air blower 221 and in communication with the interior of the first drum 21, and the first drying channel 222 is located on the side of the first plane a away from the second drum 31. In this way, the first air blower 221 drives the cold air to flow in the first drying channel 222, and the first drying channel 222 heats the cold air located therein, so that the cold air is converted into hot air and discharged from the first drying channel 222 into the interior of the first drum 21 to dry the clothes in the first drum 21. Since the first drying channel 222 is also located on the side of the first plane a and is on the same side of the first plane a as the first air blower 221, the available space on the other side of the first plane a can be further improved, which facilitates the arrangement of the second drum 31 or other structural components on the other side of the first plane a.

[0167] In addition, based on the positional relationship of the second drum 31 relative to the first drum 21 and the mounting arrangement of the second drum 31, the running stability of the second drum 31 can be further designed.

[0168] For example, in some embodiments, referring to FIGS. 14a and 15a, the clothes treatment apparatus 1000 further comprises a first connecting component 81 and a second connecting component 82, the first connecting component 81 and the second connecting component 82 are arranged at intervals along the length direction of the support beam 8, the upper end of the first connecting component 81 and the upper end of the second connecting component 82 are connected to the support beam 8 respectively, and the lower end of the first connecting component 81 and the lower end of the second connecting component 82 are connected to the second drum 31 respectively, wherein the support beam 8, the first connecting component 81, the second connecting component 82 and the second drum 31 are configured such that when the second drum 31 is connected to the support beam 8, the angles of the first connecting component 81 and the second connecting component 82 with the vertical direction are within a preset range.

[0169] In this way, the first connecting component 81 and the second connecting component 82 can be used to mount the second drum 31, and by arranging the first connecting component 81 and the second connecting component 82 at intervals along the length direction of the support beam 8, the weight of the second drum 31 borne by the support beam 8 can be dispersed, thereby facilitating the stability and reliability of the mounting of the second drum 31.

[0170] Applicants have found that the support beam 8 will deform in the up-down direction of the clothes treatment apparatus 1000 under the action of gravity or other components mounted on the support beam 8, and this deformation can cause the second drum 31 to rotate, thereby affecting the normal operation of the second drum 31.

[0171] Therefore, the applicant specially adjusts the design elements of the first connecting member 81 and the second connecting member 82, so that when the second drum 31 is connected to the support beam 8, the angle between the first connecting member 81 and the second connecting member 82 and the vertical direction is within a preset range, thereby facilitating the guarantee of the second drum 31 in a working posture, and further facilitating the improvement of the reliability of the clothes treatment equipment 1000.

[0172] Here, the preset range refers to the range of the included angle between the first connecting member 81 and the second connecting member 82 and the vertical direction without affecting the normal working of the second drum 31. For example, after the second drum 31 is hung on the support beam 8 through the first connecting member 81 and the second connecting member 82, the angle of the second drum 31 rotating around its own axis can be not more than 0°-10°, thereby facilitating the guarantee of the second drum 31 in a working posture, and at this time, the preset range can be 0°-10°. Of course, the specific angle can also be designed according to the type and requirements of the second drum 31, and the present disclosure does not limit this.

[0173] Here, the vertical direction can be the up-down direction of the clothes treatment equipment 1000, and the deformation of the support beam 8 in the vertical direction can be the natural bending of the support beam 8 downward due to its own gravity, or the bending of the support beam 8 downward due to the gravity of the second drum 31 or other structures (such as the counterweight assembly 5), and the present disclosure does not limit this.

[0174] The above-mentioned adjustment of the design elements of the first connecting member 81 and the second connecting member 82 includes but is not limited to the adjustment of the positions of the upper end of the first connecting member 81 and the upper end of the second connecting member 82 connected to the support beam 8, the positions of the lower end of the first connecting member 81 and the lower end of the second connecting member 82 connected to the second drum 31, the distance between the upper end of the first connecting member 81 and the lower end of the first connecting member 81, the distance between the upper end of the second connecting member 82 and the lower end of the second connecting member 82, and the like, and the specific embodiments will be introduced below.

[0175] As an example, as an implementation, referring to FIG. 14a, the upper end of the first connecting member 81 is connected to the first portion 83 of the support beam 8, and the upper end of the second connecting member 82 is connected to the second portion 84 of the support beam 8. The support beam 8 is in a curved state in the vertical direction, and at least some points on the first portion 83 are lower than points on the second portion 84 in the vertical direction. For example, in the up-down direction of the laundry treating apparatus 1000, the deformation degree of the first portion 83 is greater than that of the second portion 84. In this way, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 are connected to portions of the support beam 8 that have different degrees of deformation, respectively. In this arrangement, adjustment of the first connecting member 81 and the second connecting member 82 is more likely to overcome the problem of the target structure rotating due to the support beam 8 being curved by gravity.

[0176] Optionally, referring to FIGS. 15b to 15f, the lower end of the first connecting member 81 is adapted to be connected to the first point with the second tub 31, and the lower end of the second connecting member 82 is adapted to be connected to the second point with the second tub 31. In the vertical direction, the distance from the first point to the profile surface d of the support beam 8 is a first distance, and the distance from the second point to the profile surface d is a second distance. The profile surface d is a curved surface on which the profile of the support beam 8 lies. It can be understood that the profile surface d can be the bottom surface of the support beam 8 when the support beam 8 does not have a concave-convex structure in the up-down direction.

[0177] Since the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are connected to the first point and the second point with the second tub 31, respectively, that is, the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are connected at different positions of the second tub 31, respectively, the stability of the connection between the support beam 8 and the second tub 31 is improved.

[0178] Optionally, referring to FIGS. 15b to 15f, when the support beam 8 is curved downward due to its own gravity or the gravity of a suspended structure or other structure (such as the counterweight assembly 5), the profile surface d on which the first portion 83 lies can be lower than the profile surface d on which the second portion 84 lies.

[0179] In the present disclosure, the support beam 8 can be connected to the upper end of the first connecting member 81 by any suitable structure. As some implementations of the present disclosure, referring to FIGS. 15b to 15f, the upper end of the first connecting member 81 can be connected to the profile surface d, and the distance between the upper end and the lower end of the first connecting member 81 is equal to the first distance. Alternatively, the bottom surface of the support beam 8 is provided with a protruding portion that protrudes downward, the upper end of the first connecting member 81 is connected to the protruding portion, and the protruding portion is below the profile surface d. Alternatively, the bottom surface of the support beam 8 is provided with a recessed portion that is recessed upward, the upper end of the first connecting member 81 is connected to the recessed portion, and the recessed portion is above the profile surface d.

[0180] In the present disclosure, the support beam 8 can be connected to the upper end of the second connecting member 82 by any suitable structure. As some embodiments of the present disclosure, referring to FIGS. 15b-15f, the upper end of the second connecting member 82 can be connected to the profile surface d, the distance from the upper end to the lower end of the second connecting member 82 can be equal to the second distance, or the bottom surface of the support beam 8 can be provided with a protrusion protruding downward, the upper end of the second connecting member 82 can be connected to the protrusion, and the protrusion can be located below the profile surface d, or the bottom surface of the support beam 8 can be provided with a recess recessed upward, the upper end of the second connecting member 82 can be connected to the recess, and the recess can be located above the profile surface d.

[0181] The present disclosure does not limit the specific position where the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are connected to the second cylinder 31. As an embodiment, referring to FIGS. 15b-15e, the lower end of the first connecting member 81 and the lower end of the second connecting member 82 can be located at the same height, i.e., the lower end of the first connecting member 81 and the lower end of the second connecting member 82 can be flush. This can allow the second cylinder 31 to be connected to the lower end of the first connecting member 81 and the lower end of the second connecting member 82 through a conventional connection position, without the need to modify the second cylinder 31, thereby facilitating the reduction of the manufacturing difficulty of the second cylinder 31.

[0182] As another embodiment of the present disclosure, as shown in FIG. 15f, the height of the lower end of the first connecting member 81 can be lower than the height of the lower end of the second connecting member 82, and in the vertical direction, the distance from the upper end of the first connecting member 81 to the lower end of the first connecting member 81 can be equal to the distance from the upper end of the second connecting member 82 to the lower end of the first connecting member 81. That is, by adjusting the connection position of the second cylinder 31 to the first connecting member 81 and the second connecting member 82, the connection position of the lower end of the first connecting member 81 to the second cylinder 31 can be adjusted to be lower than the connection position of the lower end of the second connecting member 82 to the second cylinder 31, and the position of the upper end of the first connecting member 81 can be adapted to the height of the downward bending of the first portion 83, thereby keeping the angle of rotation of the second cylinder 31 within a predetermined range.

[0183] In this embodiment, since the distance between the upper and lower ends of the first connecting member 81 and the distance between the upper and lower ends of the second connecting member 82 can be equal, the first connecting member 81 and the second connecting member 82 can use the same connecting member, thereby facilitating the connection of the second cylinder 31 to the support beam 8.

[0184] In the embodiment where the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are located at the same height, in order to keep the angle of rotation of the second cylinder 31 within a predetermined range, the present disclosure provides the following embodiments:

[0185] As a first embodiment, as shown in FIG. 15b, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 are both connected to the profile surface d, and in the vertical direction, the distance from the upper end of the first connecting member 81 to the lower end of the first connecting member 81 is less than the distance from the upper end of the second connecting member 82 to the lower end of the second connecting member 82.

[0186] That is, by adjusting the distance from the upper end of the first connecting member 81 to the lower end of the first connecting member 81 and the distance from the upper end of the second connecting member 82 to the lower end of the second connecting member 82, the height of the upper end of the first connecting member 81 can be adapted to the height of the profile surface d in the first portion 83, thereby facilitating the angle of rotation of the second cylinder 31 to remain within a predetermined range.

[0187] Furthermore, in this embodiment, since no other structure needs to be constructed on the support beam 8, the manufacturing and processing difficulty and cost of the support beam 8 can be reduced.

[0188] As a second embodiment, as shown in FIG. 15c, the upper end of the first connecting member 81 is connected to the profile surface d, the bottom surface of the support beam 8 is provided with a downward protruding protrusion, the upper end of the second connecting member 82 is connected to the protrusion, and the protrusion is below the profile surface d, and in the vertical direction, the distance from the upper end of the first connecting member 81 to the lower end of the first connecting member 81 is equal to the distance from the upper end of the second connecting member 82 to the lower end of the second connecting member 82.

[0189] That is, by adapting the height of the downward protruding protrusion of the second portion 84 to the height of the profile surface d in the first portion 83, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 can be at the same height, thereby facilitating the angle of rotation of the second cylinder 31 to remain within a predetermined range when the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are at the same height.

[0190] As a third embodiment, as shown in FIG. 15d, the bottom surface of the support beam 8 is provided with an upward recessed recess, the upper end of the first connecting member 81 is connected to the recess, and the recess is above the profile surface d, the bottom surface of the support beam 8 is provided with a downward protruding protrusion, the upper end of the second connecting member 82 is connected to the protrusion, and the protrusion is below the profile surface d.

[0191] That is, by adapting the height of the upward recessed recess of the first portion 83 to the height of the downward protruding protrusion of the second portion 84, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 can be at the same or similar height, thereby facilitating the angle of rotation of the second cylinder 31 to remain within a predetermined range when the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are at the same height.

[0192] It can be understood that in this embodiment, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 can be located at the same or similar height, that is, the distance between the upper and lower ends of the first connecting member 81 can be greater than the distance between the upper and lower ends of the second connecting member 82, the distance between the upper and lower ends of the first connecting member 81 can be equal to the distance between the upper and lower ends of the second connecting member 82, and the distance between the upper and lower ends of the first connecting member 81 can be less than the distance between the upper and lower ends of the second connecting member 82.

[0193] As a fourth embodiment, referring to FIG. 15e, the bottom surface of the support beam 8 is provided with a concave portion recessed upward, the upper end of the first connecting member 81 is connected to the concave portion, the concave portion is located above the profile surface d, and the upper end of the second connecting member 82 is connected to the profile surface d. In the vertical direction, the distance from the upper end of the first connecting member 81 to the lower end of the first connecting member 81 is equal to the distance from the upper end of the second connecting member 82 to the lower end of the second connecting member 82.

[0194] That is, the height of the upwardly recessed concave portion of the first portion 83 and the height of the profile surface d located at the second portion 84 are matched, so that the upper end of the first connecting member 81 and the upper end of the second connecting member 82 can be located at the same height, thereby facilitating the second cylinder 31 to keep the angle of rotation within a predetermined range when the lower end of the first connecting member 81 and the lower end of the second connecting member 82 are located at the same height.

[0195] In the second embodiment, the third embodiment and the fourth embodiment described above, since the distance between the upper and lower ends of the first connecting member 81 can be equal to the distance between the upper and lower ends of the first connecting member 81, the first connecting member 81 and the second connecting member 82 can be set to the same length, so that the first connecting member 81 and the second connecting member 82 can use the same specification connecting member, which not only facilitates to reduce the cost of manufacturing the first connecting member 81 and the second connecting member 82, but also facilitates to improve the versatility of the first connecting member 81 and the second connecting member 82, and reduce the assembly difficulty of the support beam 8 and the second cylinder 31.

[0196] Moreover, the first connecting member 81 and the second connecting member 82 have the same length, the upper end of the first connecting member 81 and the upper end of the second connecting member 82 have the same height, and the lower end of the second connecting member 82 and the lower end of the second connecting member 82 have the same height, which facilitates the first connecting member 81 and the second connecting member 82 to be in a symmetrical state with the second cylinder 31 as the center, thereby facilitating to improve the stability of the second cylinder 31 hanging on the support beam 8.

[0197] Here, optionally, the first connecting member 81 and the second connecting member 82 can each be configured to be integrally formed with the second cylinder 31, or integrally formed with the support beam 8, or partially integrally formed with the second cylinder 31 or the support beam 8, and the present disclosure does not limit this. For example, the connecting member (the first connecting member 81 and the second connecting member 82) as a whole can be an integral piece with the second cylinder 31 or the support beam 8, or part of the connecting member (the first connecting member 81 and the second connecting member 82) can be an integral piece with the washing tub or the support beam 8.

[0198] The above-described various adjustment modes of the first connecting member 81 and the second connecting member 82 are all conducive to keeping the angle of rotation of the second cylinder 31 within a preset range during the deformation of the support beam 8 in the vertical direction, and a person skilled in the art can select according to actual conditions.

[0199] Based on the concept of connecting the second cylinder 31 to the support beam 8 and the concept of designing the stability of the second cylinder 31, further improvements can be made according to the vibration of the support beam 8.

[0200] For example, in some embodiments, referring to FIGS. 14a and 15a, the top surface of the support beam 8 can be provided with a receiving recess 85 adapted to accommodate the upper end of the first connecting member 81. It can be understood that the vibration generated during the operation of the laundry treating apparatus 1000 will also be transmitted to the support beam 8, causing different parts of the support beam 8 to vibrate to different degrees. In view of this, as an embodiment, the support beam 8 can include a first portion 83 and a second portion 84, the vibration amplitude of the first portion 83 being greater than that of the second portion 84, i.e., when the support beam 8 vibrates, the first portion 83 can be closer to the structure above the support beam 8 than the second portion 84, at this time, the receiving recess 85 and the first connecting member 81 are located in the first portion 83, and the second connecting member 82 is located in the second portion 84.

[0201] In other words, the receiving recess 85 can be provided at the part of the support beam 8 that can vibrate to a greater amplitude, so that the upper end of the first connecting member 81 can be accommodated by the receiving recess 85, reducing or eliminating the occupation of the space above the support beam 8 by the first connecting member 81, thereby facilitating the reduction of the distance between the top of the housing 1 and the support beam 8, or allowing other structures of the laundry treating apparatus 1000 to be arranged above the support beam 8, so that the internal space of the housing 1 can be more reasonably utilized, thereby facilitating the housing 1 to be smaller in size and the laundry treating apparatus 1000 to occupy less space. In addition, it is conducive to reducing the possibility of interference between the support beam 8 or the first connecting member 81 and the structure above the support beam 8 (such as the inner top wall of the housing 1) when the support beam 8 vibrates, thereby facilitating the safe and stable operation of the laundry treating apparatus 1000.

[0202] In addition, the receiving recess 85 is not arranged on the second portion 84 of the support beam 8, i.e., the receiving recess 85 is arranged only on the portion of the support beam 8 where large amplitude vibration is likely to occur, and the receiving recess 85 is not arranged on the portion of the support beam 8 where small amplitude vibration is likely to occur, so as to reduce the processing complexity of the support beam 8 and save the processing cost of the support beam 8 while ensuring that the support beam 8 or the second connecting member 82 does not interfere with the structure above the support beam 8.

[0203] For example, the depth of the receiving recess 85 can be set to 2.5 mm to 3.5 mm. In this way, the receiving recess 85 can well accommodate the upper end of the first connecting member 81, and the downward protrusion of the support beam 8 corresponding to the receiving recess 85 can effectively shorten the length of the first connecting member 81.

[0204] For example, the depth of the receiving recess 85 can be set to 3 mm, the second connecting member 82 connected to the second portion 84 can protrude from the top surface of the support beam 8 by a length of 6.25 mm, and the upper end of the first connecting member 81 connected to the first portion 83 can protrude from the top surface of the support beam 8 by a length of only 3.25 mm because it is accommodated in the receiving recess 85, so as to facilitate avoiding interference between the upper end of the first connecting member 81 connected to the first portion 83 and the structure above the support beam 8 when the support beam 8 vibrates.

[0205] In addition, based on the concept that the support beam 8 extends in the left-right direction to span above the first cylinder 21 and the second cylinder 31, the layout of some components can be further improved using the support beam 8, for example, the pipeline arrangement is further optimized.

[0206] For example, in some embodiments, the second cylinder 31 is connected to the support beam 8, the support beam 8 extends in the left-right direction perpendicular to the first central axis and the second central axis, and the laundry treating apparatus 1000 includes a mounting path adapted to fix a pipeline of the laundry treating apparatus 1000.

[0207] It can be understood that, since the laundry treating apparatus 1000 is exemplarily provided with the first drum 21 and the second drum 31, the second drum 31 is arranged above the first drum 21 on the right, thus the pipeline for the second drum 31 needs to be arranged at least partially across the first drum 21. The support beam 8 is adapted to be arranged inside the laundry treating apparatus 1000 and adapted to have at least a first mounting path extending along the left-right direction of the laundry treating apparatus 1000, thus at least part of the pipeline of the laundry treating apparatus 1000 can be fixed to the support beam 8 along the first mounting path by adding a fixing member. In this way, the pipeline arranged inside the laundry treating apparatus 1000 will not be shaken randomly under the vibration of the first drum 21 and / or the second drum 31, and the fixed pipeline is not easy to collide with other components of the laundry treating apparatus 1000, effectively avoiding the situation that the pipeline and / or other components inside the laundry treating apparatus 1000 are easily damaged due to the pipeline being easily shaken and easily colliding with other components (such as the first drum 21 and the second drum 31) of the laundry treating apparatus 1000 when the laundry treating apparatus 1000 is in use.

[0208] The present disclosure does not limit the specific fixing manner of the pipeline arranged along the first mounting path on the support beam 8, as long as the pipeline can be reliably fixed on the support beam 8. As an embodiment of the present disclosure, the support beam 8 can be provided with a first mounting hole 7007, and the fixing member can include a first cable tie, which is arranged through the first mounting hole 7007 to fix the pipeline to the support beam 8. In other words, at least part of the pipeline inside the laundry treating apparatus 1000 is bundled on the support beam 8 by the first cable tie, the pipeline is reliably fixed on the support beam 8, and the pipeline is convenient to disassemble and assemble.

[0209] As another embodiment of the present disclosure, the above-mentioned fixing member can also be formed as a first buckle connected to the above-mentioned support beam 8, and the pipeline can be clamped to the above-mentioned first buckle to be fixed on the support beam 8.

[0210] It can be understood that the support beam 8 can be arranged at the top of the laundry treating apparatus 1000 to facilitate the installation of the second drum 31, in order to reduce the possibility that the pipeline is crushed by the shell 1 of the laundry treating apparatus 1000 and the support beam 8 when the laundry treating apparatus 1000 is in use, and the first cable tie is used to fix the pipeline to the bottom surface of the support beam 8. In this way, even if the support beam 8 vibrates under the action of the first drum 21 and / or the second drum 31 when the laundry treating apparatus 1000 is in use, the pipeline fixed below the support beam 8 will not be squeezed by the shell 1 of the laundry treating apparatus 1000 and the support beam 8, and the pipeline is not easy to be damaged, effectively improving the service life of the pipeline.

[0211] Exemplarily, referring to FIG. 14b, the mounting path includes a second mounting path located on the support plate 7006, which is arranged at the rear side of the second drum 31, and is suitable for guiding and connecting the pipeline to the corresponding device of the second drum 31. In other words, a section of the pipeline in the clothes treatment apparatus 1000 (such as the pipeline corresponding to the second drum 31) can be fixed on the support beam 8, and other sections of the pipeline can also be fixed on the support plate 7006. The first mounting path arranged on the support beam 8 and the second mounting path on the support plate 7006 can be used together to fix the pipeline, which can not only meet the bending and routing requirements of the pipeline, but also increase the fixed length of the pipeline and improve the fixing effect of the pipeline.

[0212] Here, it should be noted that the specific type of the corresponding device to which the pipeline is connected is not limited in the present disclosure. The pipeline can be connected to any device corresponding to the second drum 31, for example, the device can be a drain air box 90, etc.

[0213] The present disclosure also does not limit the specific fixing manner of the pipeline arranged along the second mounting path on the support plate 7006. As long as the pipeline can be reliably fixed on the support plate 7006. As an embodiment of the present disclosure, the support plate 7006 is provided with a second mounting hole 7008, and the pipeline fixing structure further includes a second cable tie, which is arranged through the second mounting hole 7008 to fix the pipeline to the support plate 7006. In other words, another part of at least part of the pipeline in the clothes treatment apparatus 1000 can also be fixed on the support plate 7006 by the second cable tie. The pipeline is reliably fixed on the support plate 7006, and is convenient to disassemble and assemble.

[0214] In some embodiments, referring to FIGS. 14a and 15a, the support beam 8 has a first face and a second face arranged opposite to each other, the first face faces the first drum 21 and the second drum 31 downward, and the second face faces the top of the shell 1. The first face of the support beam 8 is provided with a avoiding structure 86 to achieve the avoiding of the components in the shell 1.

[0215] Exemplarily, the avoiding structure 86 can be configured as a protrusion 861 on the support beam away from the components, so as to achieve the avoiding of the components, and is very convenient to manufacture, that is, the protrusion 861 can be obtained directly by extrusion deformation of the support beam 8. In addition, a buffer gap is reserved between the protrusion 861 and the shell 1, so that enough space is kept between the protrusion 861 and the shell 1 to avoid collision between the protrusion 861 and the shell 1 when the support beam 8 vibrates with the first drum 21 and / or the second drum 31, so that the reliability of the support beam 8 can be maintained.

[0216] In reference to FIG. 11, the second drum 31 can be connected to the support beam 8, and thus the above-mentioned components can be, for example, a drying device for the second drum 31, such as a drying fan or an air inlet duct 341, so that the drying fan or the air inlet duct 341 can be avoided by the protrusion 861 when the support beam 8 is deformed by vibration. Of course, the above-mentioned components can also be pipeline structures and the like of the laundry treatment apparatus 1000, and the present disclosure does not specifically limit this.

[0217] The second drum 31 is hoisted by the support beam 8, which solves the interference problem between the first drum 21 and the second drum 31, but occupies the space of the related internal devices originally arranged at this position. Based on this, in some embodiments, in reference to FIGS. 14a and 15a, the support beam 8 can include a hanging section 87 and an extension section 88, wherein the hanging section 87 is used for mounting the second drum 31, so that the second drum 31 is arranged above the side of the first drum 21. For example, the second drum 31 can be arranged above the right side of the first drum 21, and thus the left side of the support beam 8 can be configured as the extension section 88, and the size of at least a partial region of the extension section 88 is smaller than the size of the hanging section 87, so as to form an avoiding section 89 recessed in the front-rear direction, which is used for avoiding the internal devices. The avoiding section 89 formed on the extension section 88 can accommodate the related internal devices that originally contact or interfere with the extension section 88, so as to achieve avoidance with the internal devices, thereby reducing the space occupation of the extension section 88 in the front-rear direction, and realizing the arrangement of the support beam 8 without expanding the overall size of the housing 1 and without changing the mounting position of the above-mentioned internal devices.

[0218] In addition, since the second drum 31 is suspended below the hanging section 87, when the second drum 31 vibrates, it will drive the hanging section 87 to vibrate synchronously and make the hanging section 87 have a larger amplitude. Since the extension section 88 is relatively far from the second drum 31, its amplitude is relatively small. In the present disclosure, the size of the extension section 88 in the front-rear direction is set to be smaller than the size of the hanging section 87 in the front-rear direction, so that the extension section 88 is more likely to vibrate under the vibration of the hanging section 87 connected to the second drum 31, and the amplitude of the extension section 88 during vibration can be increased, so that the amplitude of the extension section 88 is consistent with the amplitude of the hanging section 87 as much as possible, avoiding the problem of uneven stress on the support beam 8 due to the inconsistent amplitudes of the hanging section 87 and the extension section 88, thereby improving the stability and service life of the support beam 8.

[0219] It can be understood that when the second cylinder 31 is arranged above the right side of the first cylinder 21, in order to ensure the rationality of the space utilization inside the housing 1, the upper left side of the first cylinder 21 can be used to arrange internal devices such as pipeline structures and control structures and the like, and thus the avoidance section 89 is formed on the side behind the extension section 88, and the size of the extension section 88 in the front-rear direction is smaller than the size of the suspension section 87 in the front-rear direction, so as to better achieve the avoidance of the internal devices arranged on the rear side, and facilitate the installation of the internal devices.

[0220] It should be noted that the internal devices can include but are not limited to the first electric control box 6 and the water inlet valve 44 (to be described below) and the like.

[0221] In addition, based on the concept of the position relationship of the second cylinder 31 relative to the first cylinder 21, such as the offset, a counterweight assembly 5 can be added to further optimize the balance of the laundry treatment apparatus 1000.

[0222] In some embodiments, referring to FIG. 18, the laundry treatment apparatus 1000 can further include a counterweight assembly 5, the second cylinder 31 is located on one side of the first plane a, and at least part of the counterweight assembly 5 is located on the other side of the first plane a away from the second cylinder 31. In this way, at least part of the counterweight assembly 5 is located on the opposite side of the side where the second cylinder 31 is located on the first plane a, which can be used to balance the weight of the second cylinder 31, and thus the laundry treatment apparatus 1000 can remain balanced during operation, so that the laundry treatment apparatus 1000 can operate stably.

[0223] The counterweight assembly 5 can be arranged in any suitable manner, for example, the counterweight assembly 5 can include a counterweight block 51, the counterweight block 51 can be connected to the support beam 8, and the counterweight block 51 is at least partially located on the opposite side of the side where the second cylinder 31 is located on the first plane a. For example, the second cylinder 31 can be located on the right side of the first plane a, and the second cylinder 31 is located above the second plane b, which is a plane parallel to the left-right direction passing through the center axis of the first cylinder 21. The counterweight block 51 can be located on the left side of the first plane a, and the counterweight block 51 is located above the second plane b, so that the counterweight block 51 can at least balance the second cylinder 31 in the left-right direction, so that the laundry treatment apparatus 1000 can remain balanced during operation.

[0224] In some embodiments, the counterweight block 51 can also be configured to dampen the vibration of the second cylinder 31. Specifically, the vibration generated by the second cylinder 31 during operation can drive the support beam 8 to vibrate with the second cylinder 31, and at this time the counterweight block 51 can slow down the vibration of the support beam 8, thereby achieving the vibration damping of the second cylinder 31, so that the second cylinder 31 can operate more stably.

[0225] It can be understood that the laundry treating apparatus 1000 further comprises functional components such as the water inlet valve 44, the electric control box, the water inlet box 4, the drainage and aeration box 90, and the drying device, and thus the counterweight assembly 5 can further comprise at least one of the water inlet valve 44, the electric control box, the water inlet box 4, the drainage and aeration box 90, and the drying device, so as to be used for balancing the second drum 31, and thus enabling the laundry treating apparatus 1000 to operate stably.

[0226] For example, the counterweight assembly 5 can be a washing box 50 for putting in and / or storing washing materials. The washing box 50 is located at the upper left of the housing 1, and the second drum 31 is located at the upper right of the housing 1, or the washing box 50 is located at the upper right of the housing 1, and the second drum 31 is located at the upper left of the housing 1.

[0227] In some embodiments, referring to FIG. 18, the laundry treating apparatus 1000 can further comprise a washing box 50 for storing washing materials, and the washing box 50 is at least partially located below the second plane b. In this way, the washing box 50 is at least partially located below the first plane a in the up-down direction, so as to save the top space in the housing 1, and facilitate the arrangement of other devices of the laundry treating apparatus 1000 in the top space of the housing 1, such as the second drum 31.

[0228] It can be understood that the arrangement position of the washing box 50 can be set according to actual use requirements. For example, the washing box 50 can be located at the opposite side of the first plane a at which the second drum 31 is located, so as to be used for balancing the second drum 31, and thus enabling the laundry treating apparatus 1000 to maintain balance during operation.

[0229] The second drum 31 can be located at the right side of the first plane a, and the second drum 31 is located above the second plane b. At this time, the washing box 50 can be located at the left side of the first plane a, and the washing box 50 is located below the second plane b. This is used for balancing the second drum 31 in the left-right direction, and thus enabling the laundry treating apparatus 1000 to maintain balance during operation.

[0230] In addition, based on the concept of the offset of the position relationship of the second drum 31 relative to the first drum 21, the first switch door 23 corresponding to the first drum 21 and the second switch door 33 corresponding to the second drum 31 can be further optimized and designed, so as to facilitate the optimization of user operation and improve user experience.

[0231] In some embodiments, referring to FIGS. 19 and 20, the first switch door 23 has a first projection surface on the front panel 14 of the housing 1 when the first switch door 23 is in the closed state, the second switch door 33 has a second lower vertex in the up-down direction of the clothes processing apparatus 1000 and a second left vertex and a second right vertex in the left-right direction of the clothes processing apparatus 1000, a fourth tangent L4 passing through the second lower vertex intersects the first projection surface when the second switch door 33 is in the closed state, and at least one of a fifth tangent L5 passing through the second left vertex and a sixth tangent L6 (not shown in the figure) passing through the second right vertex intersects the first projection surface. In this way, when both the first switch door 23 and the second switch door 33 are in the closed state, due to the fourth tangent L4 intersecting the first projection surface, the distance between the center axes of the first switch door 23 and the second switch door 33 in the up-down direction of the clothes processing apparatus 1000 is less than the sum of the radius of the first switch door 23 and the radius of the second switch door 33 in this direction, and due to at least one of the fifth tangent L5 and the sixth tangent L6 intersecting the first projection surface, the distance between the center axes of the first switch door 23 and the second switch door 33 in the left-right direction of the clothes processing apparatus 1000 is less than the sum of the radius of the first switch door 23 and the radius of the second switch door 33 in this direction. Therefore, the size of the clothes processing apparatus 1000 can be reduced to meet the installation needs of small-sized users, and since the first switch door 23 and the second switch door 33 open and close towards different directions, the use of the first switch door 23 and the second switch door 33 will not be affected.

[0232] The first switch door 23 has a first upper vertex in the up-down direction of the clothes processing apparatus 1000, and the first distance D1 is between the first tangent L1 passing through the first upper vertex and the fourth tangent L4 when the first switch door 23 is in the closed state. In this way, the first tangent L1 is higher than the fourth tangent L4 in the up-down direction of the clothes processing apparatus 1000, and therefore, the sum of the radius of the first switch door 23 and the radius of the second switch door 33 in the up-down direction of the clothes processing apparatus 1000 minus the first distance D1 is the distance between the center axes of the first switch door 23 and the second switch door 33 in this direction, so that the size of the first switch door 23 and the second switch door 33 in the up-down direction of the clothes processing apparatus 1000 can be reduced, which is beneficial to reducing the size of the clothes processing apparatus 1000.

[0233] On the basis of the above technical solutions, the clothes processing apparatus 1000 provided by the present disclosure can adaptively arrange the arrangement of the first switch door 23 and the second switch door 33 according to actual needs, and the present disclosure does not make specific limitations on this.

[0234] Exemplarily, referring to FIG. 19 and FIG. 20, the second cylinder 31 can be arranged above and right of the first cylinder 21, and the diameter of the first switch door 23 can be greater than the diameter of the second switch door 33, and the second switch door 33 is located above and right of the first switch door 23. The connection positions of the first switch door 23 and the second switch door 33 with the shell 1 can be adaptively set according to actual needs.

[0235] For example, the first switch door 23 has a first connection part 231 connected with the shell 1, and the second switch door 33 has a second connection part 331 connected with the shell 1, and the first connection part 231 and the second connection part 331 are respectively located at the left side of the first switch door 23 and the right side of the second switch door 33. The first switch door 23 can be rotated away from the second switch door 33 to open leftward, and the second switch door 33 can be rotated away from the first switch door 23 to open rightward. Thus, the first switch door 23 and the second switch door 33 can avoid each other, and ensure that the first switch door 23 and the second switch door 33 can be opened and closed at the same time.

[0236] In addition, based on the concept of the position relationship of the second cylinder 31 relative to the first cylinder 21, for example, the space at the rear of the second cylinder 31 can be further designed.

[0237] In some embodiments, the second cylinder 31 has a first end and a second end opposite in the front-rear direction, and the second end of the second cylinder 31 and the shell 1 have a containing space therebetween, and the length of the second cylinder 31 in the front-rear direction is less than the length of the first cylinder 21 in the front-rear direction. Wherein, the internal size of the second cylinder 31 is smaller, and thus in order to facilitate the taking of clothes, the length of the second cylinder 31 in the front-rear direction, that is, the depth of the second cylinder 31, will not be set too large, and thus the space between the second end of the second cylinder 31 and the inner wall of the shell 1 is large to form the containing space. In this way, by reserving the containing space between the second cylinder 31 and the inner wall of the shell 1, relevant components can be conveniently placed, so that the layout of the components inside the clothes treatment equipment 1000 is reasonable, and the utilization rate of the internal space of the clothes treatment equipment 1000 is improved.

[0238] Exemplarily, the components can be a drainage structure, which can be located in the containing space and connected with the inner wall of the shell 1, and the first cylinder 21 and / or the second cylinder 31 is provided with a drainage port, one end of the drainage structure is connected with the drainage port, and the other end of the drainage structure extends out of the shell 1. By arranging the drainage structure in the containing space, the space can be reasonably utilized, and the drainage of the washing cylinder can be realized.

[0239] In addition, the component can be an exhaust structure, which can be located in the accommodation space and connected with the inner wall of the shell 1. By arranging the exhaust structure, air in the first cylinder 21 and / or the second cylinder 31 can be exhausted outward, especially when the clothes in the first cylinder 21 and / or the second cylinder 31 are dried, high-temperature and high-humidity steam can be exhausted outward through the exhaust structure.

[0240] The above-mentioned drainage structure and exhaust structure can be a drainage and ventilation box 90 to be described below.

[0241] In addition, based on the concept of the offset position of the second cylinder 31 relative to the first cylinder 21, the stability and assembly convenience of the second cylinder 31 can be further optimized.

[0242] In some embodiments, referring to FIGS. 10 and 37, the clothes treatment apparatus 1000 further includes a crossbeam 400 for mounting the second cylinder 31 into the shell 1 and capable of supporting the second cylinder 31. Specifically, the crossbeam 400 is mounted between the front ends of the two side plates 15 of the shell 1 in the left-right direction, and in the up-down direction, the crossbeam 400 is disposed below the second cylinder 31, and the crossbeam 400 is detachably connected with the second cylinder 31 to facilitate assembly of the second cylinder 31.

[0243] In addition, the crossbeam 400 has a forward avoiding protrusion 4001. It can be understood that the second cylinder 31 is arranged above the right side of the first cylinder 21, and because the upper side of the first cylinder 21 is provided with components such as a drying device, interference with the mounting of the crossbeam 400 can occur. Therefore, the crossbeam 400 is provided with a forward avoiding protrusion 4001 to avoid interference between the drying device and the crossbeam 400. In addition, in the front-rear direction, the crossbeam 400 can be disposed in front of the first cylinder 21, and the avoiding protrusion 4001 is used to avoid the first cylinder 21.

[0244] In some embodiments, referring to FIGS. 2, 3a and 37, a first through hole 362 can be formed at a position close to the bottom of the second cylinder 31, the first through hole 362 can be formed on the above-mentioned cylinder ring 36, a second through hole 17 corresponding to the first through hole 362 can be formed on the shell 1, and a positioning rod can be arranged between the shell 1 and the second cylinder 31, wherein the positioning rod is detachably and simultaneously arranged in the first through hole 362 and the second through hole 17, so that the second cylinder 31 is locked on the shell 1, forming a fixed connection between the second cylinder 31 and the shell 1, and preventing the second cylinder 31 from freely moving relative to the shell 1.

[0245] It can be understood that, since the first through hole 362 is arranged at the bottom of the second cylinder 31, the gravity of the second cylinder 31 can be borne to prevent the second cylinder 31 from shaking relative to the shell 1 during transportation, avoid collision with other structures (for example, the first cylinder 21) inside to cause damage, and ensure the safety and stability of the equipment during transportation.

[0246] In addition, the third through hole 4002 can be arranged on the cross beam 400, and the third through hole 4002 can be arranged corresponding to the first through hole 362 and the second through hole 17 to pass through the positioning rod. In this way, by additionally arranging the third through hole 4002 on the cross beam 400, the support point of the positioning rod is increased, so that when the second cylinder 31 has a movement trend, the force can be dispersed through multiple support points to avoid stress concentration of a single limiting point, thereby improving the stability of the second cylinder 31 and the service life of the positioning structure. Moreover, arranging the support point on the cross beam 400 in the shell 1 can avoid adding too many support holes on the shell 1, which affects the appearance of the equipment.

[0247] It can be understood that the cross beam 400 can also be used for pipeline installation of the laundry treatment equipment 1000, and therefore arranging the third through hole 4002 on the cross beam 400 can effectively utilize the original structure of the equipment, save the number of parts, and occupy less internal space. It should be noted that when the shell 1 supports the positioning rod through the second through hole 17 and the third through hole 4002, the positioning rod and the second through hole 17 or the third through hole 4002 can not be fixedly connected, and under simple transportation conditions (such as horizontal linear distance transportation), the positioning rod can pass through the through holes in sequence, so as to facilitate installation and removal and simplify the transportation process.

[0248] In some embodiments, referring to FIG. 37, the rear side of the cross beam 400 can be provided with a mounting structure 500 for installing the pipeline, so as to reduce the shaking of the pipeline caused by the vibration of the first cylinder 21 and / or the second cylinder 31, thereby improving the stability during pipeline installation.

[0249] The mounting structure 500 can be adaptively constructed according to actual needs. For example, the mounting structure 500 can be used to fix the water supply pipe. Specifically, the mounting structure 500 can include a main body part 5001 and at least one elastic clamping plate 5002 connected to the main body part 5001, and the main body part 5001 is used to cooperate with the clamping plate 5002 to clamp the water supply pipe. Since the clamping plate 5002 is elastic, the clamping plate 5002 can provide an elastic force towards the water supply pipe, so that the outer surface of the water supply pipe can be pressed between the main body part 5001 and the clamping plate 5002. That is, the water supply pipe can be clamped by the clamping plate 5002 and the main body part 5001 together, so as to prevent the water supply pipe from falling off, thereby improving the installation stability of the water supply pipe through the mounting structure 500.

[0250] The clamping plate 5002 can be configured in any suitable manner. For example, the clamping plate 5002 can have a connecting plate segment 50021 and a vertical plate segment 50022. The connecting plate segment 50021 can be connected to the main body part 5001 and gradually extends away from the main body part 5001 from bottom to top. The vertical plate segment 50022 can be spaced apart from the main body part 5001. At least one of the connecting plate segment 50021 and the vertical plate segment 50022 can clamp the water delivery pipe with the main body part 5001. The connecting plate segment 50021 can connect the vertical plate segment 50022 and the main body part 5001. That is, the connecting plate segment 50021 can facilitate the spacing of the vertical plate segment 50022 and the main body part 5001, so as to facilitate the formation of a space for arranging the water delivery pipe between the clamping plate 5002 and the main body part 5001, thereby facilitating the clamping of the water delivery pipe by the clamping plate 5002 and the main body part 5001 together.

[0251] It should be noted that at least one of the connecting plate segment 50021 and the vertical plate segment 50022 can clamp the water delivery pipe with the main body part 5001. It can be understood that the connecting plate segment 50021 can be used alone to clamp the water delivery pipe with the main body part 5001, or the vertical plate segment 50022 can be used alone to clamp the water delivery pipe with the main body part 5001, or the connecting plate segment 50021 and the vertical plate segment 50022 can be used together to clamp the water delivery pipe with the main body part 5001. At this time, since the connecting plate segment 50021 and the vertical plate segment 50022 jointly abut the water delivery pipe, the contact area between the clamping plate 5002 and the water delivery pipe can be increased, thereby facilitating the stable clamping of the water delivery pipe by the clamping plate 5002 and the main body part 5001.

[0252] Based on the layout of the first cylinder 21 and the second cylinder 31, the sound insulation and the prevention of abnormal sound of the laundry treatment apparatus 1000 can be further optimized.

[0253] In some embodiments, referring to FIG. 10, the laundry treatment apparatus 1000 can further include a sound insulation member 600 disposed on the inner surface of the front panel 14 of the housing 1. The front panel 14 of the housing 1 has an opening that communicates with the inlets of the first cylinder 21 and the second cylinder 31, i.e., the opening is close to the user when the laundry treatment apparatus 1000 is in use. Therefore, the sound insulation member 600 is disposed on the inner surface of the front panel 14, and the effective position of the sound insulation member 600 is close to the user, so that the sound insulation member 600 can achieve better sound insulation effect and improve the user experience of the laundry treatment apparatus 1000.

[0254] Exemplarily, when the second cylinder body 31 is arranged above the right side of the first cylinder body 21, the sound insulation piece 600 can be arranged above the left side of the first cylinder body 21; when the second cylinder body 31 is arranged above the left side of the first cylinder body 21, the sound insulation piece 600 can be arranged above the right side of the first cylinder body 21. It can be understood that the sound insulation piece 600 can be exemplarily configured as sound insulation cotton, which can be connected to the front plate 14 by means of adhesion for replacement, and of course the sound insulation cotton can also be detachably connected to the front plate 14 by means of fastening bolts and the like, and the present disclosure does not make specific limitations thereto.

[0255] In some embodiments, with reference to FIG. 21, the clothes treating apparatus 1000 can include a door seal 34 connected to the second cylinder body 31, and a stop portion 35 can be arranged at the cylinder opening of the second cylinder body 31 and stop at the rear end of the door seal 34 to block the clothes inside the second cylinder body 31 from impacting the door seal 34 to cause abnormal sound.

[0256] It can be understood that the second cylinder body 31 can be designed to gradually expand from the cylinder bottom to the cylinder opening to facilitate the taking of clothes at the cylinder opening, and since the second cylinder body 31 is formed in a gradually expanding shape, the clothes are easily slid toward the cylinder opening to impact the door seal 34, at which time the stop portion 35 can be configured in a ring shape and form a partition between the second cylinder body 31 and the door seal 34, effectively preventing the clothes from sliding or impacting in the direction of the cylinder opening, thereby blocking the clothes inside the second cylinder body 31 from impacting the door seal 34 to cause abnormal sound. At the same time, the inner diameter of the stop portion 35 is designed to be greater than the diameter of the cylinder bottom, so that the stop portion 35 does not hinder the normal putting or taking action of the clothes, making it more convenient to store and take the clothes.

[0257] Exemplarily, the stop portion 35 can be made of rubber, since rubber materials have good softness and will not scratch or damage the clothes inside the second cylinder body 31, protecting the cleanliness and safety of the clothes. At the same time, rubber materials also have a certain deformation ability, and when the clothes are stored or taken, the stop portion 35 can be appropriately pressed and deformed to temporarily expand the size of the access opening at the cylinder opening, facilitating the putting or taking of the clothes, and returning to the original state after the clothes are stored or taken, having good stopping effect. Here, the stop portion 35 can be an integral structure with the door seal 34 to simplify the production process and improve the positioning strength of the stop portion 35, or can be sleeved and arranged at the cylinder opening of the second cylinder body 31 in the case of using rubber materials. When the two are in a split structure, the stop portion 35 can be periodically cleaned or replaced to improve the cleanliness inside the second cylinder body 31. The two mounting forms of the stop portion 35 described above can be reasonably selected according to the actual use condition and target audience of the user to have better applicability.

[0258] In addition, in terms of space utilization, the installation of the display panel assembly 300 can also be optimally designed to improve the space utilization.

[0259] In some embodiments, referring to FIG. 1, the housing 1 can further include a front plate 14, a side plate 15, and a top plate 16, a top end surface of the front plate 14 is flush with a top end surface of the side plate 15 or the top end surface of the front plate 14 is higher than the top end surface of the side plate 15, and the display panel assembly 300 is mounted to the top end surface of the front plate 14. In this way, the height of the front plate 14 is greater than or equal to the height of the side plate 15, and the display panel assembly 300 is mounted to the top end surface of the front plate 14, so that the arrangement of the display panel assembly 300 does not cause the size of the front plate 14 to be reduced in the up-down direction, so as to improve the space utilization of the clothes treatment apparatus 1000, facilitate the arrangement of other components of the clothes treatment apparatus 1000 (for example, the arrangement of the second drum 31 of the clothes treatment apparatus 1000), and also facilitate the arrangement of the display panel assembly 300.

[0260] In the clothes treatment apparatus 1000 provided in the present disclosure, the display panel assembly 300 can be arranged in any suitable manner. As an exemplary embodiment, referring to FIG. 1, the display panel assembly 300 can include a display panel 3001 and a panel fixing seat 3002, the display panel 3001 can be fixed to the panel fixing seat 3002, and the panel fixing seat 3002 can be mounted to the top end surface of the front plate 14 and overlap the top end surface of the side plate 15. In this way, the bottom end surface of the panel fixing seat 3002 can simultaneously contact the top end surface of the front plate 14 and the top end surface of the side plate 15, so that the panel fixing seat 3002 can utilize the space of the top of the front plate 14 and the top of the side plate 15 and be arranged adjacent to the top plate 16 of the clothes treatment apparatus 1000. The above arrangement can ensure that the panel fixing seat 3002 can meet the size design requirements of the display panel 3001, so as to avoid problems such as user inconvenience or incomplete operation caused by the display panel 3001 being too small in size.

[0261] In the clothes treatment apparatus 1000 provided in the present disclosure, the display panel 3001 can be arranged in any suitable manner. As an exemplary embodiment, the display panel 3001 can be fixed to an inclined mounting surface of the panel fixing seat 3002, at this time, a preset included angle θ can be formed between the display panel 3001 and the top end surface of the front plate 14, and the top end portion of the display panel 3001 can be arranged obliquely toward the top plate 16. In this way, the width of the display panel 3001 is greater than the height of the panel fixing seat 3002, so as to ensure that the space occupied by the display panel assembly 300 in the height direction of the clothes treatment apparatus 1000 is saved while meeting the size design requirements of the display panel 3001, that is, the oblique arrangement of the display panel 3001 can ensure that the overall height of the clothes treatment apparatus 1000 is not too high. In addition, the top end portion of the display panel 3001 is arranged obliquely toward the top plate 16, that is, the display panel 3001 is arranged toward the user, so as to facilitate the user to operate the display panel 3001.

[0262] In the washing machine provided in the present disclosure, the panel fixing seat 3002 can be configured in any suitable manner, and as an exemplary embodiment, the first distance H between the bottom edge of the mounting surface and the top end surface of the panel fixing seat 3002 can be less than or equal to the height of the top plate 16. In this way, the space occupied by the display panel 3001 in the height direction can be saved.

[0263] In addition, the top edge of the mounting surface can be parallel to the bottom edge of the mounting surface, and the second distance D between the top edge of the mounting surface and the bottom edge of the mounting surface can satisfy:

[0264] In the laundry treating apparatus 1000 provided in the present disclosure, the preset angle θ can be any suitable value, and as an exemplary embodiment, the preset angle θ can be 40°-55°. For example, the preset angle θ can be equal to 40°, 45°, 50°, 55°, etc., and the present disclosure does not make specific limitations thereon, that is, the display panel 3001 can be inclined and extended at any suitable angle within the range of 40°-55° according to actual needs, and compared with the existing laundry treating apparatus 1000 (the preset angle θ is generally 55°-90°), the preset angle θ of the present application can ensure that the space occupied by the display panel 3001 in the height direction is reduced, so as to ensure that the size of the laundry treating apparatus 1000 in the up-down direction can be controlled within a reasonable range, in other words, the total height of the laundry treating apparatus 1000 provided in the present application can be the same as that of the laundry treating apparatus 1000 in the prior art, that is, the present disclosure can not only satisfy the arrangement of the display panel assembly 300, but also not increase the overall height of the laundry treating apparatus 1000. The preset angle θ can be preferably 50°, and the present disclosure does not make specific limitations thereon.

[0265] As an exemplary embodiment, the width L of the display panel 3001 can be less than or equal to the second distance D. That is, the display panel 3001 will not exceed the mounting surface, thereby improving the aesthetics of the laundry treating apparatus 1000.

[0266] In the laundry treating apparatus 1000 provided in the present disclosure, the second distance D of the display panel 3001 can be any suitable value, and as an exemplary embodiment, the second distance D of the display panel 3001 is 17 mm-85 mm. For example, the second distance D of the display panel 3001 can be set to 17 mm, 25 mm, 35 mm, 45 mm, 55 mm, 65 mm, 75 mm, 85 mm, etc., and the present disclosure does not make specific limitations thereon, wherein the second distance D of the display panel 3001 can be preferably 17 mm-40 mm, and further preferably 39 mm, and the present disclosure does not make specific limitations thereon.

[0267] In the laundry treating apparatus 1000 provided by the present disclosure, as an exemplary embodiment, referring to FIG. 1, the display panel assembly 300 can be arranged above the second tub 31, thus the display panel assembly 300 provided by the present disclosure can improve the space utilization of the front plate 14, and can ensure the internal space of the first tub 21 and the second tub 31, so as not to affect the arrangement of the first switch door 23 and the second switch door 33, and to ensure the washing capacity of the laundry treating apparatus 1000.

[0268] Based on the overall inventive concept, the drying flow path of the first tub and the second tub can be further optimized. For example, under the driving of the fan, the airflow is heated by the heating device and then blown into the corresponding tub, and then the high-temperature and high-humidity steam body becomes dry under the action of the condensing device. The dry gas can be directly discharged from the laundry treating apparatus, or can be heated again by the fan through circulation. The condensed water after condensation can be discharged through the water outlet of the laundry treating apparatus.

[0269] Based on this, the drying flow path can be further designed, for example, the condensing device can be further optimized.

[0270] In some embodiments, referring to FIG. 17, the laundry treating apparatus 1000 can further include a condensing disc 40. The first tub 21 and the second tub 31 in the above description each include an inner tub and an outer tub, and the outer tub serves to contain and support the inner tub. The condensing disc 40 is arranged between the bottom of the inner tub and the bottom of the outer tub. The high-temperature and high-humidity gas discharged from the inner tub becomes dry after heat exchange with the condensing disc 40, the dry gas is heated by the drying air duct and then returns to the inner tub, and the condensed water is discharged from the outer tub through the water outlet at the bottom of the outer tub.

[0271] Specifically, the condensing disc 40 can include a disc body 401, one side of the disc body 401 facing the bottom of the outer tub is provided with a flow channel 402 for the flow of cooling medium, and the flow channel 402 is configured to enable the cooling medium to flow circumferentially in the cavity formed by the disc body 401 and to fill the cavity. In this way, the condensing disc 40 of the present disclosure is designed by reasonably designing the flow channel 402, so that the flow track of the low-temperature cooling medium in the cavity is circumferential flow around the condensing disc 40 and can fill the cavity. This is conducive to increasing the contact area of the low-temperature cooling medium with the disc body 401, thereby prolonging the flow time of the cooling medium in the cavity, and further facilitating sufficient heat exchange between the high-temperature and high-humidity gas in the inner tub and the condensing disc 40, improving the heat exchange efficiency, which can further improve the intake amount of the dry gas into the drying air duct, thereby improving the drying efficiency.

[0272] In the above embodiments, it has been described that the first fan 221 is arranged on the outer wall of the first drum 21, and the first fan 221 drives the cold air to flow in the first drying channel 222, and the first drying channel 222 heats the cold air located therein, so that the cold air is converted into hot air by being heated, and the hot air is discharged from the first drying channel 222 into the inside of the first drum 21 to dry the clothes in the first drum 21. In this process, the high-temperature and high-humidity steam body becomes dry after passing through the condensing disc 40 in the first drum 21, and the dry gas is circulated by the first fan 221, and the condensed water is discharged through the water outlet.

[0273] In addition, for the drying of the second drum 31, in some embodiments, referring to FIGS. 11, 21 and 22, the clothes treatment apparatus 1000 further comprises a second drying channel 321 in communication with the inner cavity of the second drum 31, wherein the front end of the second drum 31 can be provided with a drum ring 36, and the drum ring 36 can be provided with circumferentially distributed mounting holes, and the drum ring 36 is detachably connected to the second drum 31 by fasteners passing through the mounting holes. The front end of the drum ring 36 can be provided with a door seal 34, that is, the door seal 34 is mounted on the second drum 31 through the drum ring 36 to seal.

[0274] The door seal 34 can be elastically sleeved on the outer periphery of the drum ring 36 and be tightened by a wire or the like; or the door seal 34 can be connected by a clamping manner. The door seal 34 and the second drum 31 form a communication internal space therebetween, and the second drying channel 321 can be connected to the door seal 34, so as to be in communication with the inner cavity of the second drum 31 to dry the clothes in the second drum 31. The second drying channel 321 can include a first section, a second section and a transition section. The first section can extend along the left-right direction of the clothes treatment apparatus 1000. The second section can extend along the front-rear direction of the clothes treatment apparatus 1000, and the first section and the second section are connected through the transition section. When the transition section is bent at a position close to the second drum 31, it is easy to collide with the second drum 31 when vibration occurs, so a recessed portion can be formed in a region corresponding to the transition section of the second drying channel 321 to avoid the transition section. Exemplarily, a recessed portion 361 can be formed in a region of the front end face of the drum ring 36 corresponding to the transition section of the second drying channel 321, and the recessed portion 361 is recessed from the front end face to the rear end face, so that the second drum 31 can avoid the vibration of the transition section in the front-rear direction through the recessed portion 361 when working vibration occurs, to prevent the transition section from colliding with the drum ring 36 to generate abnormal sound and reduce the service life, and to avoid collision to further improve the use stability of the whole apparatus.

[0275] In some embodiments, referring to FIG. 22, the door seal 34 can be provided with an air inlet and communicates with the second drying channel 321 through an air inlet duct 341, so that the hot air in the second drying channel 321 can enter the second drum 31 through the air inlet duct 341 and the air inlet, thereby shortening the length of the second drying channel 321 and facilitating the assembly of the drying device for the second drum 31 with the second drum 31 and the door seal 34. In addition, by extending the air inlet duct 341 in the left-right direction, the size of the air inlet duct 341 can be increased, so as to increase the air volume entering the second drum 31 without being limited by the connection of the first drying channel 222 and the door seal 34. In addition, the air inlet duct 341 and the door seal 34 body can be integrally formed to facilitate manufacturing.

[0276] It can be understood that the upper wall surface of the air inlet duct 341 can be arranged as high as possible, so as to increase the cross-sectional area of the air inlet duct 341 and increase the air inlet amount, and the upper wall surface of the air inlet duct 341 does not exceed the tangent line of the top point of the door seal 34, which can avoid installation interference in the up-down direction and avoid contact or collision with the upper parts such as the support beam 8, etc. In particular, the second drum 31 also vibrates, and the air inlet duct 341 also vibrates slightly, so the above arrangement can improve the overall reliability.

[0277] In addition, the hot air in the second drum 31 can be discharged to the outside of the clothes treatment apparatus 1000 through the second exhaust duct 37.

[0278] In addition, referring to FIGS. 22 and 31, the second drum assembly 3 can further include a second exhaust duct 37, and the dry hot air entering the second drum 31 exchanges heat with the wet clothes, and then is discharged through a drainage ventilation box 90. For the convenience of description, the specific structure of the drainage ventilation box 90 will be described below. In this way, the hot and humid air enters the ventilation cavity 901 in the drainage ventilation box 90 through the second exhaust duct 37, and then is discharged through the outer exhaust port 9011. The drainage ventilation box 90 is arranged at the rear of the second drum 31 in the front-rear direction, that is, the space at the rear of the second drum 31 can be effectively utilized, and the utilization rate of the space in the housing 1 of the clothes treatment apparatus 1000 is improved.

[0279] Exemplarily, one side of the side wall of the second cylinder 31 in the left-right direction can be formed with an exhaust port, the second exhaust pipe 37 is integrally arranged on the outer side wall of the second cylinder 31 and communicates with the exhaust port, the exhaust port is arranged at the rear side edge of the side wall of the second cylinder 31, the second exhaust pipe 37 is protrudingly arranged on the outer side wall of the second cylinder 31 in the left-right direction and protrudes rearward from the rear cylinder wall of the second cylinder 31; wherein the lower end of the drainage ventilation box 90 protrudes downward from the lower end of the second cylinder 31, and the upper end of the drainage ventilation box 90 is located below the upper end of the second cylinder 31.

[0280] In this way, first, by arranging the exhaust port at the rear side edge of the side wall of the second cylinder 31 and protruding the second exhaust pipe 37 rearward from the rear cylinder wall of the second cylinder 31, it is convenient to connect with the drainage ventilation box 90 arranged at the rear of the second cylinder 31, and the design length of the second exhaust pipe 37 is effectively shortened. However, the specific arrangement position of the exhaust port is not limited in the present disclosure. Secondly, by integrally arranging the second exhaust pipe 37 on the outer side wall of the second cylinder 31 and communicating with the exhaust port, the second exhaust pipe 37 can be installed and removed without the need for installation and removal, the degree of integration is high, and the structural strength of the second exhaust pipe 37 can also be effectively guaranteed. In addition, the lower end of the drainage ventilation box 90 protrudes downward from the lower end of the second cylinder 31, and the upper end of the drainage ventilation box 90 is located below the upper end of the second cylinder 31, effectively utilizing the space at the lower part without occupying too much space at the upper part, which is beneficial to the arrangement and installation of other structural members. In addition, the second exhaust pipe 37 and the drainage ventilation box 90 can be connected by a rubber pipe.

[0281] In addition, based on the overall inventive concept, the water supply flow path of the first cylinder 21 and the second cylinder 31 can be further optimized.

[0282] For example, in the water supply flow path, the material in the feeding box 70 can be delivered into the first cylinder 21 and the second cylinder 31 by a pumping device.

[0283] Specifically, in some embodiments, referring to FIG. 2, the laundry treating apparatus 1000 can further include a dosing box 70 and a pumping device for pumping the material in the dosing box 70 into the first drum 21 and / or the second drum 31, by which the conveying force can be insufficient to convey the material into the first drum 21 and / or the second drum 31. It can be understood that the present disclosure exemplarily provides that the second drum 31 is arranged at the upper right, and the dosing box 70 can be arranged at the lower left. Considering the layout that the second drum 31 and the first drum 21 are staggered left and right in the up-down direction, the centers of gravity of the two drums are not on the same vertical line, and the laundry treating apparatus 1000 can shake due to the unstable center of gravity during operation. Thus, the dosing box 70 and the second drum 31 are diagonally arranged, and the dosing box 70 can also function as a counterweight to a certain extent, that is, it can balance the center of gravity offset of the second drum 31, and improve the safety performance of the laundry treating apparatus 1000 during use.

[0284] The dosing box 70 can be configured to include a first material bin and a second material bin in communication, the first material bin being configured to accommodate the material stock solution, and the second material bin being configured to accommodate the mixture of the material stock solution and water, and the pumping device being in communication with the second material bin. Generally, the material stock solution has a high concentration and needs to be diluted before being conveyed into the drum, and thus, the first material bin serves as a storage bin for the stock solution, and the second material bin serves as a storage bin for the water solution after dilution. The second material bin can be in communication with the water inlet pipeline, and during the process of water inlet into the first drum 21 and / or the second drum 31, part of the water is flushed into the dosing box 70 to dilute the material stock solution for use in laundry washing.

[0285] It can be understood that when the laundry treating apparatus 1000 is normally operated, for example, during a drying operation, the inside of the laundry treating apparatus 1000 is in a high-temperature and high-heat environment, and condensate water is easily generated. If the condensate water drops onto the power supply device below, a short circuit can occur, which can cause a safety risk. The drying operation mainly occurs at the top inside the housing 1. In some embodiments, referring to FIG. 23, the laundry treating apparatus 1000 can further include a flow guide 60 arranged at the top inside the housing 1 to guide the condensate water to the side of the housing 1 and discharge the same. For example, the flow guide 60 can be arranged at the front panel 14 of the housing 1, which can extend toward the inside of the housing 1 to provide a mounting base for arranging the flow guide 60, which can be integrally formed with the front panel 14 to ensure structural strength. In this way, the condensate water can flow to at least one side of the front panel 14 in the left-right direction under the action of the flow guide 60, so that the condensate water can be prevented from flowing out of the flow guide 60 from the middle of the front panel 14, and the adverse effect of the condensate water on the power supply device below can be avoided. At this time, the two sides of the front panel 14 can abut against the two side panels 15, respectively, so that the condensate water can flow down along the side panels 15. It can be understood that some devices below the side panels 15, such as reinforcing members, can not be affected by the condensate water.

[0286] The flow guide 60 can include a main body section 601 and a guide section 602 connected to the end of the main body section 601 and extending downwardly inclined from the main body section 601, and the main body section 601 and the guide section 602 can collectively form a flow guide passage, and a flow guide opening can be arranged at the end of the guide section 602 away from the main body section 601. In this way, the condensate water of the main body section 601 can flow to the guide section 602 and flow out of the flow guide 60 through the flow guide opening under the action of gravity. In the present disclosure, the guide section 602 extends downwardly inclined from the main body section 601, that is, the depth of the main body section 601 is less than the depth of the guide section 602 in the flow guide 60, so that other devices (such as the second tub 31) can be arranged below the main body section 601, and thus the space utilization of the laundry treating apparatus can be improved.

[0287] It can be understood that, in order to reduce the possibility that the condensate water contacts the terminal assembly of the dispensing drawer 70 and causes a short circuit, the present disclosure exemplary separates the dispensing drawer 70 and the terminal assembly of the dispensing drawer 70, and arranges the terminal assembly of the dispensing drawer 70 at the top of the housing 1. For example, the dispensing drawer 70 can be arranged at the lower left inside the housing 1, and the terminal assembly of the dispensing drawer 70 can be arranged at the upper left inside the housing 1 to avoid the first tub 21 and the second tub 31 and related structures arranged inside the housing 1.

[0288] Exemplarily, the wiring terminal assembly 701 of the dosing box 70 can be arranged at the top end of the left side plate 15 of the shell 1. In order to improve the assembly efficiency of the wiring terminal assembly 701, a positioning structure, such as a positioning pin and a positioning hole, can be arranged between the wiring terminal assembly 701 and the left side plate 15, so as to facilitate the positioning of the wiring terminal assembly 701 on the left side plate 15.

[0289] Specifically, the wiring terminal assembly 701 can include a wiring port 7011 and a mounting bracket 7012. The wiring port 7011 can be used for inserting a plug of a wire harness (not shown) for electrically connecting the dosing box 70. The wiring port 7011 can also be electrically connected to a main control board (not shown) of the clothes treatment apparatus 1000, so that the dosing box 70 is in communication connection with the main control board. The mounting bracket 7012 can be provided with a receiving groove for receiving the wiring port 7011. The mounting bracket 7012 can be fixedly connected to the shell 1, so as to realize the relative fixation between the wiring port 7011 and the shell 1.

[0290] In some embodiments, referring to FIGS. 2, 11, 25 and 26, the clothes treatment apparatus 1000 can include a water inlet valve 44 and a water inlet box 4 communicating the water inlet valve 44 and the first drum 21 and / or the second drum 31. The water inlet box 4 provided in the present disclosure is internally provided with a plurality of water paths.

[0291] It can be understood that the water inlet box 4 provided in the present disclosure is an integrated water path design. Specifically, the water path is formed in the water inlet box 4 by means of, for example, a convex rib, so as to be distinguished from the design of an external water pipe commonly used in the related art. The integrated water path has the advantage that the arrangement of the water path is relatively concentrated in the interior of the water inlet box 4, and does not need to be fixed like an external water pipe, thereby being able to save more design space, so as to improve the space rationality of the clothes treatment apparatus 1000.

[0292] In some embodiments, the water path includes a first water path 41 communicating the water inlet valve 44 and a second water path 42 communicating the first drum 21. The first water path 41 serves as a water inlet path, so that water from the water inlet valve 44 can enter the water inlet box 4. The second water path 42 serves as a water outlet path, so that water in the water inlet box 4 can enter the first drum 21.

[0293] In addition, the water inlet box 4 can be provided with a first water inlet interface 411 and a first water outlet interface 412 communicating with the first water channel 41, and a second water inlet interface 421 and a second water outlet interface 422 communicating with the second water channel 42, wherein the first water inlet interface 411 is adapted to communicate with the water inlet valve 44, the first water outlet interface 412 is adapted to communicate with the dosing box 70 for accommodating washing materials, the second water inlet interface 421 is adapted to communicate with the dosing box 70, and the second water outlet interface 422 is adapted to communicate with the first cylinder 21.

[0294] The water inlet box 4 can be designed as a standard structure, and when the water inlet system or the laundry treatment device 1000 is assembled, only the pipeline needs to be connected to the corresponding interface of the water inlet box 4. In this embodiment, the water inlet box 4 is adapted to communicate with the dosing box 70, the water flowing into the water inlet box 4 at least partially enters the dosing box 70, and the washing materials in the dosing box 70 can be flushed into the second water channel 42. The backflushing pressure can be achieved through the closed water inlet system, and the water flushed into the second water channel 42 enters the first cylinder 21.

[0295] In addition, the water channel further includes a third water channel 43 communicating with the second cylinder 31, and the second water channel 42 corresponding to the first cylinder 21 and the third water channel 43 corresponding to the second cylinder 31 can be configured as water channels that do not interfere with each other.

[0296] The water inlet box 4 can also be provided with a third water inlet interface 431 and a third water outlet interface 432 communicating with the third water channel 43, wherein the third water inlet interface 431 is adapted to communicate with the dosing box 70, and the third water outlet interface 432 is adapted to communicate with the second cylinder 31. In this way, the water flowing into the water inlet box 4 at least partially enters the dosing box 70, and the materials in the dosing box 70 can be flushed into the second water channel 42 and the third water channel 43. The water in the second water channel 42 enters the first cylinder 21, and the water in the third water channel 43 enters the second cylinder 31.

[0297] In addition, the outer wall surface of the water inlet box 4 can be provided with a pipeline fixing structure. Exemplarily, the communication pipeline between the above-mentioned dosing box 70 and the terminal of the dosing box 70 can be fixed through the pipeline fixing structure of the outer wall surface of the water inlet box 4. That is, the water inlet box 4 internally integrates the water channel for water flow, and externally serves as a carrier for fixing the pipeline, which can be understood as a dual-purpose of the water inlet box 4. In this way, the pipeline can be laid and fixed against the outer wall surface of the water inlet box 4. On the one hand, the pipeline fixing structure of the outer wall surface of the water inlet box 4 is directly utilized, without the need for additional fixing structures such as wire grooves or cable ties, thereby saving material costs, and on the other hand, the pipeline is arranged against the water inlet box 4, which is further conducive to saving design space.

[0298] In some embodiments, referring to FIG. 11, the laundry treating apparatus 1000 can include a first water supply pipe 45 and a second water supply pipe 46, a water inlet of the first water supply pipe 45 being in communication with the second water outlet interface 422, a water outlet of the first water supply pipe 45 being in communication with the first drum 21, a water inlet of the second water supply pipe 46 being in communication with the third water outlet interface 432, and a water outlet of the second water supply pipe 46 being in communication with the second drum 31.

[0299] It can be understood that the second drum 31 is arranged above the right side of the first drum 21, and the water inlet box 4 is adaptively arranged on the left side in consideration of the reasonable arrangement of the space in the housing 1, so that the second water supply pipe 46 is arranged above the first drum 21 and extends along the left-right direction to span the first drum 21 to meet the water supply requirement of the second drum 31. In addition, the first water supply pipe 45 and the second water supply pipe 46 are both connected with the same dosing box 70, and the external water source enters the dosing box 70 through the water inlet valve 44 and the first water path 41, and the washing material in the dosing box 70 can be carried away and delivered to the first drum 21 and the second drum 31 through the first water supply pipe 45 and the second water supply pipe 46, respectively, without additional water inlet valve 44, dosing box 70 and other structures, so that the first water supply pipe 45 and the second water supply pipe 46 are reasonably arranged, and the integrity of the internal layout of the laundry treating apparatus 1000 can be improved.

[0300] In some embodiments, referring to FIGS. 11 and 27a, the laundry treating apparatus 1000 can further include a backflushing water pipe 48 in communication with the drainage and aeration box 90 (to be described below), the backflushing water pipe 48 being in communication with the second water supply pipe 46, and the backflushing water pipe 48 can be directly communicated to the second air exhaust pipe 37 or indirectly communicated to the second air exhaust pipe 37 through the drainage and aeration box 90. For example, referring to FIGS. 29 and 30, when the backflushing water pipe 48 is communicated to the second air exhaust pipe 37 through the drainage and aeration box 90, the drainage and aeration box 90 is internally provided with an aeration cavity 901 and a drainage cavity 902 which are independent of each other and are separately arranged, and the water outlets of the second air exhaust pipe 37 and the backflushing water pipe 48 are respectively in communication with the aeration cavity 901. The foam overflowing from the aeration cavity 901 through the second air exhaust pipe 37, and the backflushing water pipe 48 is communicated with the aeration cavity 901, so as to realize the purpose of backflushing the foam into the first drum 21.

[0301] Referring to FIGS. 29 and 30, the drain vent box 90 can be provided with an air inlet 9012 of the vent cavity 901, a backflush water pipe interface 481, and an outer air outlet 9011, respectively, wherein the outer air outlet 9011 is in communication with the outside environment, the air inlet 9012 is in communication with the second air pipe 37, and the backflush water pipe interface 481 is in communication with the backflush water pipe 48. In this way, the foam overflowing from the second drum 31 into the second air pipe 37 can be backflushed into the second drum 31. In this way, when some foam overflows from the second drum 31 into the second air pipe 37, in order to avoid the foam continuing to overflow out of the laundry treating apparatus 1000, the water outlet of the second water supply pipe 46 can be caused to enter the backflush water pipe 48, and the foam is backflushed back into the second drum 31. The foam can be re-dissolved during the backflushing process and in the second drum 31, and even if the undissolved foam is blocked by the backflushing water, it will not overflow from the second air pipe 37, but will be drained from the drain line of the second drum 31, thereby playing a role in dissolving the foam and avoiding pollution of the indoor environment.

[0302] It can be understood that a water guide structure can be provided in the second air pipe 37 and / or the drain vent box 90, for guiding at least part of the water discharged from the backflush water pipe 48 into the second drum 31. For example, a water guide structure can be provided in the second air pipe 37, for guiding at least part of the water discharged from the backflush water pipe 48 into the first drum 21. The water guide structure can be, for example, a guide slope. In other embodiments, the second air pipe 37 can be inclined and the low end can be located on one side of the second drum 31, which is also conducive to guiding the water discharged from the backflush water pipe 48 into the second drum 31.

[0303] It should be noted that the backflushing here refers to the direction opposite to the direction of gas or foam overflowing from the air pipe line, i.e., if the direction of gas discharge is defined as from inside to outside, the backflushing here refers to the direction from outside to inside.

[0304] For example, a three-way valve 47 can be provided on the second water supply pipe 46, and the three-way valve 47 can be in communication with the air pipe line through the backflush water pipe 48. By providing the three-way valve 47, the backflush water pipe 48 can be selectively turned on and off, i.e., the three-way valve 47 can be opened as needed, for example, when it is monitored that no foam overflows into the air pipe line, the backflush water pipe 48 can be closed to save water.

[0305] In some embodiments, as shown in FIGS. 28a and 28b, the second outer cylinder 312 can be provided with a mounting seat 80, and the mounting seat 80 is integrally provided with a second drain port 801 and a fixing portion 802 for inserting a heater (not shown in the figure). It should be noted that the mounting seat 80 can be made of metal such as aluminum, and the heater can be a PTC (Positive Temperature Coefficient) heater, which can quickly transfer heat to the water in the inner cylinder to play a heating role. The heater and the fixing portion 802 can be in interference fit, or can be connected by clamping or bonding, and the fixing portion 802 can be integrally formed with the seat body or separately processed, which all belong to the protection scope of the present disclosure, and the present disclosure does not make specific limitations in this regard.

[0306] In the mounting seat 80 provided by the present disclosure, the heater can be inserted into the fixing portion 802 of the mounting seat 80 first, and then the mounting seat 80 is fixed at a suitable position to realize the integration of the heating and drainage functions of the second cylinder body 31, thereby improving the integration degree, and the installation of the heater and the drainage pipeline of the second cylinder body 31 can be completed at one time, improving the assembly efficiency and reducing the occupied space.

[0307] The second drain port 801 can be connected with a second drainage pipeline 803, and the second drainage pipeline 803 is arranged on the outer surface of the mounting seat 80 to communicate with the outside, and the fixing portion 802 is arranged on the inner surface of the mounting seat 80. The second drainage pipeline 803 and the fixing portion 802 are arranged in parallel and extend in opposite directions. Exemplarily, the outer peripheral wall of the outer cylinder of the second cylinder body 31 is provided with a second protruding portion 804 protruding radially outward, the inner cavity of the second protruding portion 804 communicates with the inside of the second cylinder body 31, the rear end of the second protruding portion 804 has a mounting port communicating with the inner cavity, and the mounting seat 80 is detachably mounted on the rear end of the second protruding portion 804 and inserted into the mounting port. After the mounting seat 80 is mounted on the second protruding portion 804, the mounting seat 80 can close the opening of the second protruding portion 804. The second protruding portion 804 is at least partially arranged on the first side of the lowest point of the second cylinder body 31 and is arranged obliquely, and the first side is the side of the second cylinder body 31 away from the object to be avoided (for example, the first cylinder body 21). Here, the "lowest point" refers to the point where the washing water in the second cylinder body 31 will gather under the action of gravity under normal installation of the second cylinder body 31. The obliquely arranged second protruding portion 804 can avoid the first cylinder body 21, the overall layout is more reasonable, the space occupied by the clothes treatment equipment as a whole is reduced, and the vibration of the first cylinder body 21 can be avoided from being transmitted to the second cylinder body 31. The second protruding portion 804 is arranged close to the lowest point, which can improve the drainage efficiency, ensure that all the water can be drained, reduce the residual moisture, and avoid the breeding of bacteria and mold.

[0308] The second protruding portion 804 is arranged close to the rear end of the second cylinder 31 and extends in the axial direction, the fixing portion 802 with the heater is located in the inner cavity of the second protruding portion 804, and the drain port of the second protruding portion 804 is arranged towards the rear end. The second protruding portion 804 protrudes radially outward to form an inner cavity, and the inner cavity accommodating the heater does not occupy additional space. At the same time, the heater is located in the inner cavity of the second protruding portion 804, and the washing water does not directly impact the fixing portion 802 and the heater, thereby avoiding damage to the heater. The second protruding portion 804 is arranged close to the rear end, and the drain port thereof is arranged towards the rear end, thereby adopting a direct drainage manner and achieving smoother drainage.

[0309] In addition, in order to improve the drainage efficiency, as shown in FIG. 22, a flow guide portion 805 is arranged in the second cylinder 31. The flow guide portion 805 can be configured as an arc-shaped guide slope, and the circumferential width of the arc-shaped guide slope gradually increases from the front end to the rear end of the second cylinder 31, so as to guide the washing water to the inner cavity of the second protruding portion 804 and drain out through the second drain port 801 arranged on the mounting seat 80. The shape, size, etc. of the guide slope can be limited as required. In this way, the flow guide portion 805 can optimize the water flow path, reduce vortex and water flow dead angle, achieve smoother drainage, make the water drain out of the second cylinder 31 more quickly, improve the dehydration efficiency, avoid accumulation of water in the second cylinder 31, maintain the cleanliness of the clothes treatment equipment 1000, and reduce the frequency of maintenance and cleaning.

[0310] The inner cavity of the second protruding portion 804 is connected with the inner cylinder of the second cylinder 31, and the mounting seat 80 is detachably mounted on the end face of the second protruding portion 804 through fasteners. After the mounting seat 80 is mounted on the end face of the second protruding portion 804, the opening at the rear end of the second protruding portion 804 can be closed to avoid liquid leakage. The washing water in the inner cylinder is heated in the inner cavity of the second protruding portion 804, and the heated water can return to the inner cylinder during the rotation of the second cylinder 31, so as to improve the temperature of the washing water and improve the washing efficiency. Then, the washing water can be drained out through the second drain pipeline 803.

[0311] In the inner cavity of the second protruding portion 804, the fixing portion 802 can completely wrap the heater to avoid contact between the heater and the water in the inner cavity of the second protruding portion 804, thereby achieving the sealing effect. The installation of the heater and the installation of the drain pipe are arranged staggered, and the layout is performed on the limited space of the mounting seat 80, thereby better integrating the drainage and heating functions. The second protruding portion 804 can be formed in various ways. The second protruding portion 804 can be integrally protruded outward from the cylinder wall of the outer cylinder, or can be separately processed and then mounted on the outer peripheral wall of the outer cylinder, and the present disclosure does not make specific limitation in this regard.

[0312] In some embodiments, with reference to FIGS. 2, 29 and 30, the laundry treating apparatus 1000 can further include a drain and ventilation box 90 applied to the second drum 31, the drain and ventilation box 90 communicating with the second drain line 803 described above, an inner portion of the drain and ventilation box 90 being provided with a ventilation cavity 901 and a drain cavity 902 which are independent and separated from each other, and the drain and ventilation box 90 being further provided with an outer air outlet 9011 and at least one air inlet 9012, the outer air outlet 9011 and the air inlet 9012 both communicating with the ventilation cavity 901. The drain cavity 902 is provided with a plurality of drain passages 9021 which communicate with each other, and the drain and ventilation box 90 is provided with an outer drain outlet 9022 and a plurality of water inlets 9023, the water inlets 9023 being provided one-to-one corresponding to the drain passages 9021, and the water inlets 9023 communicating with upstream ends of the corresponding drain passages 9021, and the outer drain outlet 9022 communicating with a plurality of downstream ends of the plurality of drain passages 9021.

[0313] It can be understood that, by providing the ventilation cavity 901 and the drain cavity 902, the gas entering from the air inlet 9012 can be discharged through the outer air outlet 9011 after entering the ventilation cavity 901. The drain water of the laundry treating apparatus 1000 can enter the plurality of drain passages 9021 through the plurality of water inlets 9023, and since the plurality of drain passages 9021 communicate with each other in the drain cavity 902, the water can be discharged from the drain cavity 902 through the outer drain outlet 9022. In addition, the ventilation cavity 901 and the drain cavity 902 are independent and separated from each other, that is, the drain and ventilation structure of the present disclosure integrates the ventilation cavity 901 and the drain cavity 902 in the drain and ventilation box 90, which can both drain and ventilate, has a compact structure design, high integration, and effectively reduces the number of parts and cost.

[0314] Specifically, with reference to FIGS. 29 and 30, the plurality of drain passages 9021 include a first drain passage 90211 and a second drain passage 90212, and the plurality of water inlets 9023 include a first water inlet 90231 and a second water inlet 90232; an upstream end of the first drain passage 90211 communicates with the first water inlet 90231, and a downstream end of the first drain passage 90211 communicates with the outer drain outlet 9022; an upstream end of the second drain passage 90212 communicates with the second water inlet 90232, and a downstream end of the second drain passage 90212 communicates with the downstream end of the first drain passage 90211 and the outer drain outlet 9022. The second drain line 803 described above communicates with the second water inlet 90232, and a first drain line 242 (to be described below) communicates with the first water inlet 90231. In addition, an air exhaust line communicating with the second drum 31 communicates with the air inlet 9012.

[0315] It can be understood that, in order to facilitate the control of the drainage and exhaust of the second cylinder 31, referring to FIGS. 27a, 27b and 32, the second cylinder assembly 3 can further comprise a first sensor 38 and a second sensor 39, which are respectively installed on the drainage flow path and the exhaust flow path. In the present disclosure, the first sensor 38 and the second sensor 39 can be installed on the drainage flow path and the exhaust flow path in any suitable manner, for example, they can be inserted into the second exhaust pipe 37 and the second drainage pipe 803 by means of insertion, so as to detect the temperature.

[0316] Exemplarily, the first sensor 38 and the second sensor 39 can be electrically connected to the first control box 6 through the wiring structure 700 and the support beam 8 at the same time, so as to be able to constrain the wire harness through the support beam 8, for example, by passing a cable tie or a connecting buckle through the first mounting hole 7007 to fix the first wire harness 381 of the first sensor 38 and the second wire harness 391 of the second sensor 39, so as to facilitate the wire harness of the first sensor 38 and / or the second sensor 39 to cross the wiring above the first cylinder 21 and be electrically connected to the first control box 6.

[0317] The wiring structure 700 can comprise a sensor mounting seat 7001, a sensor fixing member 7002 and a fastener, the sensor mounting seat 7001 is provided with a mounting cavity for inserting the second sensor 39, the sensor fixing member 7002 is provided with a fixing hole, and the fastener is used to pass through the second sensor 39 and be screwed with the fixing hole, so as to fix the second sensor 39 to the sensor mounting seat 7001, thereby realizing the fixation of the second sensor 39 to the exhaust flow path.

[0318] Among them, the first wire harness 381 of the first sensor 38 is electrically connected to the first control box 6 after passing through the first fixing part 7003 arranged on the drainage flow path, a plurality of second fixing parts 7004 arranged on the second cylinder 31, and a plurality of third fixing parts 7005 arranged on the top plate 16, and the second wire harness 391 of the second sensor 39 is electrically connected to the first control box 6 after passing through a plurality of second fixing parts 7004 arranged on the main cylinder cavity and a plurality of third fixing parts 7005 arranged on the top plate 16. At this time, the first wire harness 381 of the first sensor 38 and the second wire harness 391 of the second sensor 39 can converge at the second fixing part 7004, that is, in this case, the first wire harness 381 and the second wire harness 391 can pass through the second fixing part 7004 and the third fixing part 7005 at the same time, or can be fixed to the second fixing part 7004 and the third fixing part 7005 at the same time through a wire harness cable tie.

[0319] In addition, in the above technical solution, the first wire harness 381 of the first sensor 38 can be electrically connected with the first electric control box 6 through the support beam 8, and the first wire harness 381 of the first sensor 38 can be constrained through the support beam 8. Similarly, the second wire harness 391 of the second sensor 39 can also be electrically connected with the first electric control box 6 through the support beam 8, and the second wire harness 391 of the second sensor 39 can be constrained through the support beam 8. In this way, the wire harness of the first sensor 38 and / or the second sensor 39 can be wired across the first cylinder 21 in the left-right direction and electrically connected with the first electric control box 6. In addition, since part of the second exhaust pipe 37 and the backflushing water pipe 48 is located in the accommodation space, the first wire harness 381 can be electrically connected with the fourth electric control box 63 through the part of the second exhaust pipe 37 and the backflushing water pipe 48 located in the accommodation space, and the first wire harness 381 of the first sensor 38 can be constrained through the part of the second exhaust pipe 37 and the backflushing water pipe 48 located in the accommodation space. Here, the second wire harness 391 can also be electrically connected with the fourth electric control box 63 through the part of the second exhaust pipe 37 and the backflushing water pipe 48 located in the accommodation space, and the second wire harness 391 can be constrained through the part of the second exhaust pipe 37 and the backflushing water pipe 48 located in the accommodation space. In this way, the wire harness of the first sensor 38 and / or the second sensor 39 can be wired in the front-back direction and connected with the fourth electric control box 63.

[0320] In some embodiments, referring to FIG. 33, the clothes treating apparatus 1000 further includes a first water level detecting member 100, which can be used to detect the water level in the first cylinder 21. In the related art, water level detection is often detected by a pressure sensor, which usually does not directly measure the water level, but indirectly judges the water level height by detecting the change of air pressure. For the installation of the pressure sensor, it is often arranged at the top to avoid the interference of device vibration on the accuracy of the pressure sensor. It can be understood that, in order to avoid the second cylinder 31, the first water level detecting member 100 can be lowered to be detachably connected to the fourth side beam 73 to realize the reasonable arrangement of the space in the housing 1.

[0321] It can be understood that, taking the arrangement of the second cylinder 31 above the right of the first cylinder 21 as an example, at this time, the upper space of the housing 1 is limited, and therefore the first water level detecting member 100 can be connected to the fourth side beam 73. In this way, the stability of the installation of the first water level detecting member 100 is ensured, and the space in the housing 1 can also be reasonably utilized. In addition, by arranging the first water level detecting member 100 on the fourth side beam 73, the possibility that the detection accuracy is affected by the excessively long detection pipeline can be reduced.

[0322] In order to facilitate the maintenance or replacement of the first water level detection member 100, the mounting bracket 1001 can be provided to mount the first water level detection member 100 to the fourth side beam 73. When the first water level detection member 100 needs to be maintained or replaced, the mounting bracket 1001 can be first detached from the fourth side beam 73, and then the mounting bracket 1001 and the first water level detection member 100 thereon are taken out of the shell 1 together, and then the first water level detection member 100 is detached from the mounting bracket 1001, facilitating the operation of maintenance and replacement. The first water level detection member 100 and the mounting bracket 1001, and the mounting bracket 1001 and the fourth side beam 73 can be detachably connected by clamping or threaded fasteners, which is not limited in the present disclosure.

[0323] In some embodiments, referring to FIG. 34, the first cylinder assembly 2 can include a first protruding portion 24 connected to the first outer cylinder 212. The first protruding portion 24 is connected to the lower part of the first outer cylinder 212 and protrudes downward. The inside of the first protruding portion 24 is provided with a drainage groove penetrating through the first outer cylinder 212 to communicate with the first inner cylinder 211. The drainage groove can be used to contain water discharged from the first inner cylinder 211. In addition, the front side of the first protruding portion 24 is provided with a first drainage port 241 which communicates with the drainage groove and is arranged horizontally.

[0324] In this way, when drainage is needed, water will sink into the drainage groove under the action of gravity, and then be discharged from the drainage groove through the first drainage port 241 which communicates with the drainage groove. The first drainage port 241 can be arranged on the front side of the first protruding portion 24 and arranged forward, so as to arrange and install the drainage component in the space on the front side of the first outer cylinder 212, reduce the spatial span of the drainage component, and thus reduce the possibility of the drainage component being vibrated to collide with the bottom plate 11 of the shell 1 or the bottom component when the first outer cylinder 212 vibrates. This can effectively protect the drainage component. The drainage component can be the first drainage pipeline 242 and the first drainage pump 243 as shown in FIG. 11.

[0325] In some examples, referring to FIGS. 2, 35 and 36, the shell 1 can include a rear plate 13, and the air outlet structure 200 of the first cylinder 21 can be arranged on the rear plate 13. The air outlet structure 200 can include a connecting piece 2001 and a guide piece 2002 connected to each other. The inside of the connecting piece 2001 is formed with a first air passage 20011. The two ends of the first air passage 20011 are respectively formed with a first air inlet and a first air outlet. The first air inlet is used for the exhaust structure of the first cylinder 21, such as the first exhaust pipe, to communicate. The first air outlet is used for communication with the outside atmosphere. The guide piece 2002 is arranged opposite to the first air outlet and is used for changing the flow direction of the gas discharged from the first air outlet.

[0326] In this way, the gas in the first cylinder 21 can be discharged to the outside atmosphere in sequence through the exhaust structure, the first air inlet, the first air hole 20011 and the first air outlet. In the process of the gas flowing to the outside through the first air outlet, the gas directly impacts on the guide 2002 arranged opposite to the first air outlet and flows along the extension direction of the guide 2002, so as to change the flow direction of the gas, thereby reducing or avoiding the problem that the gas directly impacts on the wall surface behind the clothes treatment apparatus 1000 after flowing out of the first air outlet, and further improving the user experience.

[0327] Specifically, the guide 2002 can include two spaced side walls 20021 and a connecting wall 20022 connected between the two side walls 20021, the connecting wall 20022 is arranged opposite to the first air outlet, and the connecting wall 20022 and the side walls 20021 together enclose the second air hole 20012. In this way, when the gas flows into the first air hole 20011, it can flow from the first air outlet of the first air hole 20011 into the second air hole 20012 enclosed by the side walls 20021 and the connecting wall 20022, and flow into the outside atmosphere. In the above process, the connecting wall 20022 connected between the side walls 20021 can shield and block the gas flowing out of the first air hole 20011, so as to avoid the gas directly impacting on the wall surface, and the two spaced side walls 20021 can limit and guide the gas, so as to facilitate the gas to quickly flow into the outside atmosphere.

[0328] The air outlet structure 200 can be connected to the rear plate 13 of the shell 1 in any suitable manner. For example, referring to FIG. 36, the air outlet structure 200 can include at least one clamping piece 2003 and at least one positioning piece 2004, both of which are arranged on the connecting piece 2001 and protrude in a direction away from the guide 2002, so as to cooperate with the positioning hole and the clamping hole arranged on the rear plate 13, thereby achieving detachable connection with the rear plate 13. When the clamping piece 2003 is clamped with the clamping hole, the positioning piece 2004 is positioned in the positioning hole on the rear plate 13, and at this time, the first air hole 20011 is in communication with the exhaust structure of the first cylinder 21 arranged on the rear plate 13.

[0329] In this way, the clamping of the air outlet structure 200 and the rear plate 13 can be achieved through the cooperation of the clamping piece 2003 and the clamping hole, and the further positioning effect of the connection between the air outlet structure 200 and the rear plate 13 in the clamped state can be achieved through the cooperation between the positioning piece 2004 and the positioning hole. On the one hand, the cooperation between the positioning piece 2004 and the positioning hole can avoid the problem of loosening between the clamping holes during the operation of the clothes processing equipment 1000, so as to ensure the stability of the connection. On the other hand, the cooperation between the positioning piece 2004 and the positioning hole can significantly improve the positioning accuracy between the air outlet structure 200 and the rear plate 13, reduce the error caused by the positional deviation, and thus ensure the stability and accuracy of the connection. Moreover, the connection between the rear plate 13 and the air outlet structure 200 is achieved by clamping, and the mounting and dismounting operation of the air outlet structure 200 can be achieved without the aid of installation tools, which has the advantages of simple structure and convenient operation.

[0330] Exemplarily, the clamping piece 2003 can include an insertion part 20031 and a stop part 20032 connected to each other, and the stop part 20032 can stop on the inner wall of the rear plate 13 when the insertion part 20031 is inserted into the clamping hole. In this way, when it is necessary to fix the air outlet structure 200 on the rear plate 13, the clamping piece 2003 can be inserted into the clamping hole. After the clamping piece 2003 is inserted into the clamping hole, the position of the stop part 20032 in the clamping hole can be adjusted by rotating the air outlet structure 200. Moreover, as the stop part 20032 is continuously rotated and inserted, the distance between the stop part 20032 and the inner wall of the rear plate 13 gradually decreases, until the stop part 20032 is attached and pressed on the inner wall of the rear plate 13, achieving the locking between the air outlet structure 200 and the rear plate 13.

[0331] The device structure and use process of the clothes processing equipment 1000 are exemplarily described in the disclosure.

[0332] In combination with the above related description, the clothes processing equipment 1000 includes a first cylinder 21 and a second cylinder 31 arranged above and right of the first cylinder 21, and a water inlet system, a drainage system, an exhaust system, and a drying system serving the first cylinder 21 and the second cylinder 31.

[0333] The water inlet system includes a water inlet valve 44, a water inlet box 4, a feeding box 70, a first water inlet pipe 45, and a second water inlet pipe 46. In order to avoid the first cylinder 21 and the second cylinder 31 and to reasonably utilize the space in the shell 1, most of the water inlet system is arranged in the left space in the shell 1. For example, the water inlet valve 44 can be placed at the rear left in the shell 1. Specifically, referring to FIGS. 2, 9a, and 9b, the water inlet valve 44 is at the rear side of the first electric control box 6 which is mounted on the third side beam 72 and the fourth side beam 73. Referring to FIGS. 11, 25, and 26, the water inlet box 4 is located at the left side of the first cylinder 21 and close to the front end of the shell 1. The water inlet box 4 extends in the up-down direction. The water inlet pipe 49 connected to the water inlet valve 44 and the water inlet box 4 passes through the wiring channel 304 on the pipeline support 30 at the left side of the first electric control box 6. The feeding box 70 can be arranged between the first cylinder 21 and the bottom plate 11 and closer to the left side relative to the right side of the shell 1 in order to avoid the first drain pump 243 and the first drain pipe 242 of the first cylinder 21. For example, the feeding box 70 extends from the lower side of the first cylinder 21 to the left side so as to play a role of counterweight to a certain extent.

[0334] The water inlet box 4 is used to communicate the water inlet valve 44, the feeding box 70, the first cylinder 21, and the second cylinder 31. The water inlet box 4 provided by the present disclosure is internally provided with a plurality of water paths. Specifically, the water paths include a first water path 41 communicating with the water inlet valve 44, a second water path 42 communicating with the first cylinder 21, and a third water path 43 communicating with the second cylinder 31. The second water path 42 corresponding to the first cylinder 21 and the third water path 43 corresponding to the second cylinder 31 can be configured as water paths that do not interfere with each other.

[0335] The water inlet box 4 can be provided with a first water inlet interface 411 and a first water outlet interface 412 communicating the first water path 41, a second water inlet interface 421 and a second water outlet interface 422 communicating the second water path 42, and a third water inlet interface 431 and a third water outlet interface 432 communicating the third water path 43. The first water inlet interface 411 is adapted to communicate with the water inlet valve 44. The first water outlet interface 412 is adapted to communicate with the feeding box 70 for containing washing materials. The second water inlet interface 421 is adapted to communicate with the feeding box 70. The second water outlet interface 422 is adapted to communicate with the first cylinder 21 through the first water inlet pipe 45. The third water inlet interface 431 is adapted to communicate with the feeding box 70. The third water outlet interface 432 is adapted to communicate with the second cylinder 31 through the second water inlet pipe 46. The second water inlet pipe 46 is arranged above the first cylinder 21 and extends along the left-right direction to span the first cylinder 21. In this way, the water flowing into the water inlet box 4 at least partially enters the feeding box 70 and can flush the materials in the feeding box 70 into the second water path 42 and the third water path 43. The water in the second water path 42 enters the first cylinder 21, and the water in the third water path 43 enters the second cylinder 31.

[0336] The water inlet box 4 can be designed as a standard structure, and when the water inlet system is assembled, only the pipeline needs to be connected to the corresponding interface of the water inlet box 4. Among them, the water inlet box 4 is adapted to communicate with the dosing box 70, and the water flowing into the water inlet box 4 at least partially enters the dosing box 70, and can flush the washing material in the dosing box 70 into the second waterway 42. The backflushing pressure can be realized through the closed water inlet system, and the water flushed into the second waterway 42 enters the first cylinder 21 in turn.

[0337] In addition, the backflushing water pipe 48 communicating with the exhaust pipe of the second cylinder 31 can be arranged on the second water pipe 46, so as to be able to flush the foam overflowing from the second cylinder 31 into the exhaust pipe back into the second cylinder 31. A three-way valve 47 can be arranged on the second water pipe 46, and the backflushing water pipe 48 communicates with the three-way valve 47, so as to be selectively turned on and off through the three-way valve 47, thereby realizing on-demand water supply.

[0338] For example, when water needs to be added to the second cylinder 31, the water inlet valve 44 can be opened, and a reversing valve (which can be arranged in the water inlet box 4) can be started. The first water outlet of the reversing valve communicates with the water inlet 9023 of the second cylinder 31 through the third waterway 43 and the second water pipe 46, and the second water outlet of the reversing valve communicates with the water inlet 9023 of the first cylinder 21 through the second waterway 42 and the first water pipe 45. Among them, the water inlet 9023 of the second cylinder 31 is higher than the water inlet 9023 of the first cylinder 21.

[0339] At this time, the external water source can enter the water inlet box 4 through the first waterway 41 and carry the washing material into the second cylinder 31 from the third waterway 43. At this time, since the reversing valve is in the starting state, the reversing valve will not conduct the second waterway 42, so that the first cylinder 21 will not be watered.

[0340] It can be understood that the second water pipe 46 needs to partially cross the first cylinder 21, so the length of the second water pipe 46 is relatively long, and there is more residual water in the second water pipe 46. The laundry treatment apparatus 1000 first closes the water inlet valve 44 in response to determining that the water filling of the second cylinder 31 is completed, and then closes the reversing valve in response to determining that there is no residual water in the second water pipe 46. Specifically, a flow meter can be arranged in the second water pipe 46, or it is determined that there is no residual water in the second water pipe 46 after a certain preset time. Since the reversing valve is closed again in the case that there is no residual water in the second water pipe 46, even if the reversing valve is closed to conduct the second waterway 42 and the first water pipe 45, there will be no residual water flowing into the first cylinder 21, thereby improving the user experience.

[0341] In the water inlet system of the laundry treatment apparatus 1000, the washing water is introduced into the water inlet valve 44 from the upper rear left of the housing 1, and the water inlet valve 44 supplies the washing water to the water inlet box 4 through the water inlet pipe 49, and then the washing water is supplied to the dosing box 70 through the water inlet box 4 and carries the washing material to the water inlet box 4, and the washing water carrying the washing material in the water inlet box 4 is supplied to the first drum 21 and the second drum 31 through the first water supply pipe 45 and the second water supply pipe 46, respectively, wherein the first water supply pipe 45 is located at least partially above the front of the first drum 21 to supply the washing water to the inside of the first drum 21 from the top of the front end of the first drum 21. The second water supply pipe 46 is located above the first drum 21 and across the first drum 21, and the second water supply pipe 46 is located at least partially above the front of the second drum 31 to supply the washing water to the inside of the second drum 31 from the top of the front end of the second drum 31.

[0342] The drainage system includes a first drainage structure for the drainage of the first drum 21, a second drainage structure for the drainage of the second drum 31, and a drainage air box 90, as shown in FIGS. 11, 27a and 27b, the drainage air box 90 and the second drainage structure are mostly arranged in the upper right of the housing 1 in the reserved accommodation space between the second drum 31 and the rear plate 13, wherein the drainage air box 90 is located in the part of the accommodation space close to the rear plate 13 so that the drainage and exhaust of the second drum 31 are configured to be directly backward to improve the drainage and exhaust efficiency of the second drum 31, and facilitate wiring through the second drainage structure in the accommodation space, and improve the utilization rate of the space in the housing 1.

[0343] The second drainage structure includes a mounting seat 80, the mounting seat 80 is provided with a second drainage port 801, the outer peripheral wall of the outer drum of the second drum 31 is provided with a second protruding portion 804 protruding outward in the radial direction, the inner cavity of the second protruding portion 804 is communicated with the inner drum of the second drum 31, and the drainage port of the inner cavity of the second protruding portion 804 is arranged rearward, and the mounting seat 80 is detachably mounted on the rear end face of the second protruding portion 804 by fasteners, so that the washing water can be discharged through the second protruding portion 804 and the mounting seat 80 and then discharged through the second drainage port 801.

[0344] The first drainage structure includes a first protruding portion 24 connected to the first outer drum 212, the first protruding portion 24 is connected to the lower part of the first outer drum 212 and protrudes downward. The inside of the first protruding portion 24 is provided with a drainage groove penetrating through the first outer drum 212 to communicate with the first inner drum 211, which can be used to accommodate the water discharged from the first inner drum 211, in addition, the front side of the first protruding portion 24 is provided with a first drainage port 241 communicated with the drainage groove and arranged horizontally, which can be arranged on the front side of the first protruding portion 24 and arranged forward.

[0345] The first drain port 241 is communicated with the drain air box 90 through a first drain pipeline 242 and a first drain pump 243, and the second drain port 801 is communicated with the drain air box 90 through a second drain pipeline 803. The drain air box 90 is internally provided with a drain cavity 902, and a plurality of drain passages 9021 that are communicated with each other are arranged in the drain cavity 902. The drain air box 90 is provided with an external drain port 9022 and a plurality of water inlet ports 9023. The water inlet ports 9023 are arranged one by one corresponding to the drain passages 9021, and the water inlet ports 9023 are communicated with the upstream ends of the corresponding drain passages 9021. The external drain port 9022 is communicated with the downstream ends of the plurality of drain passages 9021. By arranging the drain cavity 902, the discharged water of the laundry treatment apparatus 1000 can enter the plurality of drain passages 9021 through the plurality of water inlet ports 9023. Since the plurality of drain passages 9021 are communicated with each other in the drain cavity 902, the water can be discharged from the drain cavity 902 through the external drain port 9022.

[0346] The plurality of drain passages 9021 include a first drain passage 90211 and a second drain passage 90212, and the plurality of water inlet ports 9023 include a first water inlet port 90231 and a second water inlet port 90232. The upstream end of the first drain passage 90211 is communicated with the first water inlet port 90231, and the downstream end of the first drain passage 90211 is communicated with the external drain port 9022. The upstream end of the second drain passage 90212 is communicated with the second water inlet port 90232, and the downstream end of the second drain passage 90212 is communicated with the downstream end of the first drain passage 90211 and the external drain port 9022. The second drain pipeline 803 is communicated with the second water inlet port 90232, and the first drain pipeline 242 is communicated with the first water inlet port 90231.

[0347] The exhaust system comprises a first exhaust structure for the exhaust of the first drum 21, a second exhaust structure for the exhaust of the second drum 31, and a drainage vent box 90.
