Description

TECHNICAL FIELD

[0001] The present application relates to a multi-cylinder laundry treating apparatus. BACKGROUND

[0002] With the progress of the laundry machine industry technology and the improvement of people's cleaning awareness, consumers pay more and more attention to the healthy washing of laundry machines, especially for the mother and baby groups. Consumers gradually begin to separate underwear, socks, and large category of clothes for washing, and the demand for zoned cleaning of small and close-fitting clothes / baby clothes is increasing, so the multi-cylinder laundry machine is needed for zoned cleaning. However, the current market has upper and lower double-zoned washing / drying machines or single mini laundry machines, which can only separate and process one of underwear / underwear / socks or baby clothes from other clothes, and when multiple sensitive clothes need to be processed in zones, multiple sequential feeding is still needed, which affects the household efficiency. At the same time, due to the space limitation, the drying effect of the existing mini laundry machine is weak.

[0003] In the existing multi-cylinder laundry treating apparatus, in order to dry the clothes in the clothes treating cylinder, a duct is provided in connection with the clothes treating cylinder, but the clothes treating cylinder in the prior art occupies a large space, in addition, due to the shape of the clothes treating cylinder itself, it is difficult to compactly arrange the duct and the clothes treating cylinder in the prior art in which the duct is arranged in connection with the clothes treating cylinder, as a result, the duct also occupies a large space, which leads to the problem of large size of the whole apparatus.

[0057] Hereinafter, embodiments of the present application will be described based on the accompanying drawings. It should be noted that the following description and the drawings are merely examples of the present application and are not intended to limit the present application unless otherwise specified.

[0058] <Overall Structure of Multi-Drum Laundry Processing Device>

[0059] like Figures 1-3 As shown, as a typical example, the multi-drum laundry processing apparatus 100 of the present application may be a laundry processing apparatus having four laundry processing drums.

[0060] exist Figure 1 , a front view of the appearance of a multi-drum laundry processing device 100 is shown in the figure, and the multi-drum laundry processing device 100 comprises: a box assembly 1, which uses a frame not shown in the figure to constitute the skeleton structure of the multi-drum laundry processing device 100, and by installing a metal plate or a plate-like body made of other materials on the frame, thereby constituting the outer contour of the multi-drum laundry processing device 100 and forming a cavity space inside; a first large drum 10, which is arranged in the box assembly 1 at the upper side of the multi-drum laundry processing device 100, that is, it is arranged in the box assembly 1 above the cavity space; a first small drum 20 and a second small drum 30, the outer diameters of the first small drum 20 and the second small drum 30 are smaller than those of the first large drum 10 and the second large drum 90 described later, and are both arranged below the first large drum 10, and arranged in the left-right direction in the box assembly 1, as shown in FIG. Figure 1 As shown, in the up-down direction, the first small drum 20 and the second small drum 30 are located approximately in the middle of the multi-drum laundry processing device 100, and are arranged in the box assembly 1 between the first large drum 10 and the second large drum 90 in the cavity space; and the second large drum 90 is arranged in the box assembly 1 at the lower side of the multi-drum laundry processing device 100, that is, it is arranged in the box assembly 1 at the lower part in the cavity space, and in the up-down direction, the second large drum 90 is arranged on the opposite side of the first large drum 10 relative to the first small drum 20 and the second small drum 30.

[0061] exist Figure 2 、 Figure 3FIG shows a perspective view after omitting the box assembly 1, as shown in FIG. Figure 2 、 Figure 3 As shown, in addition to the laundry processing drum including the large drum and the small drum, the box assembly 1 also accommodates a drying assembly 40, an air inlet duct 50, an air outlet duct 60, and a driving unit 80. The arrangement of the above components will be described later.

[0062] <Peripheral Structure of Clothes Processing Drum>

[0063] As a clothing processing drum, the present application includes, for example, a first large drum 10, a first small drum 20, a second small drum 30, and a second large drum 90. Thus, the present application can utilize multiple clothing processing drums to process different types of clothing respectively. For clothing processing drums, multiple clothing processing drums can be selectively used not only according to the type of clothing (for example, the size of the clothing, the material of the clothing, whether the clothing is worn outside, and other factors), but also according to the different wearers of the clothing (for example, adults, children, the elderly, patients, people in special occupations, and other factors). On the other hand, the cylindrical clothing processing drum has also become a reason for the large size. Unlike a cube, the cylindrical shape usually has the defect that the surrounding space is difficult to effectively utilize. In view of this, the inventors of the present application have made effective use of the surrounding space of the clothing processing drum, thereby being able to more compactly construct the multi-drum clothing processing device of the present application and achieve miniaturization.

[0064] The peripheral space of the clothing processing drum includes, for example, the space between the two small drums, the rear side of the two small drums, the upper side of the two small drums, the lower side of the two small drums, the rear side of the two large drums, and between the small drum and the box assembly (to the side of the first small drum 20 and the second small drum 30).

[0065] exist Figure 4 、 Figure 5 The peripheral structure of the laundry treatment drum including the first small drum 20 and the second small drum 30 of the present application is shown in FIG. Figure 6 3 shows the peripheral structure of the clothes processing drum of the present application when the first large drum 10, the first small drum 20, the second small drum 30 and the second large drum 90 are completely removed.

[0066] like Figure 4As shown, the air inlet duct 50 of the present application is configured such that at least a portion of the air inlet duct 50 is sandwiched between the first small drum 20 and the second small drum 30 in the left-right direction, or at least a portion of the air inlet duct 50 is sandwiched between at least one of the first small drum 20 and the second small drum 30 and the cabinet assembly 1 in the left-right direction (for example, at least a portion of the air inlet duct 50 is sandwiched between the first small drum 20 and the cabinet assembly 1 on the left side of the first small drum 20, and / or at least a portion of the air inlet duct 50 is sandwiched between the second small drum 30 and the cabinet assembly 1 on the right side of the second small drum 30). In this way, the space between the first small drum 20 and the second small drum 30 can be utilized as a passage for the flow of gas. As shown in the drawings, Figure 5 As shown, on the rear side of the first small drum 20, an air outlet connecting portion 61 as a part of the air outlet duct 60 is provided.

[0067] In Figure 6 , the first small drum 20 and the second small drum 30 are removed. According to Figure 6 It can be seen that the drying assembly 40 is provided on the rear side of the first small drum 20 and the second small drum 30. The drying assembly 40 is provided between the first large drum 10 and the second large drum 90 in the up-down direction. The drying assembly 40 occupies most of the space on the rear side of the first small drum 20 and the second small drum 30, the air outlet connecting portion 61 as a part of the air outlet duct 60 occupies a small part of the space on the rear side of the first small drum 20 and the second small drum 30, and the drying assembly 40 and the air outlet connecting portion 61 of the air outlet duct 60 are arranged in the left-right direction and communicate with each other. In this way, the space on the rear side of the first small drum 20 and the second small drum 30 can be fully utilized, and the first small drum 20, the second small drum 30, the drying assembly 40, at least a portion of the air inlet duct 50, and at least a portion of the air outlet duct 60 are arranged simultaneously in the horizontal direction of the space where the first small drum 20 and the second small drum 30 are located, achieving a compact layout of the peripheral structure of the clothes treatment drum.

[0068] The structure of the drying assembly 40, the air inlet duct 50, and the air outlet duct 60 will be described below based on Figures 7-11 .

[0069] <DRYING ASSEMBLY>

[0070] The drying assembly 40 is used to heat air to generate air for drying. As shown, Figure 7 The drying assembly 40 has an upper housing 41 and a lower housing 42, and the components such as a compressor, an evaporator, a condenser, etc. that are not shown are housed inside the drying assembly 40 by the upper housing 41 and the lower housing 42 being engaged together. Of course, the compressor does not necessarily have to be arranged inside the drying assembly 40, and the lower housing 42 can be provided with a structure to mount the compressor without the need for the upper housing to be engaged and covered.

[0071] In the front portion of the drying assembly 40 in the front-rear direction, that is, the wall portion opposite to the first and second small drums 20 and 30 in the front-rear direction, an opening 411 is formed, and Figure 7 The opening 411 is formed in the upper case 41 in the illustrated example, but can be formed in the lower case 42, and is not limited thereto. As shown by an arrow in Figure 7 , air from the laundry treating drum (the large drum and / or the small drum) is guided to the drying assembly 40, in which the air is heated to generate drying air, and in the present embodiment, the opening 411 is connected to an air inlet connection portion 55 of an air inlet duct 50 (see Figure 10 ) to be described later, whereby the air can be supplied to the drying assembly 40.

[0072] In Figure 8 , a perspective view of the drying assembly 40 viewed from the rear side (the side opposite to the first and second small drums 20 and 30) is shown. Also, the illustration of the driving portion 80 is omitted in Figure 8 . The upper portion of the case of the drying assembly 40 has a mounting portion, and the driving portion 80 can be provided at the mounting portion of the upper portion of the case of the drying assembly 40 and used to drive the rotation of the rotating drum in the first large drum 10. By using the upper portion of the case of the drying assembly 40 as the mounting portion for mounting the driving portion 80, it is not necessary to separately provide a mounting portion for mounting the driving portion 80, and miniaturization in the up-down direction can be achieved. More preferably, the mounting portion is provided as a recess 412, as shown in Figure 8 , the upper portion of the upper case 41 facing upward has a recess 412 for mounting the driving portion 80, and Figure 7 a structure in which the driving portion 80 is mounted in the recess 412 is shown in . By providing the recess in the drying assembly 40 to mount the driving portion 80, further miniaturization in the up-down direction can be achieved.

[0073] Further, in Figure 8 , the lower case 42 is shown as having an opening 421 for discharging drying air generated in the drying assembly 40, that is, air in the laundry treating drum is guided to the drying assembly 40 via the opening 411, the air is heated to drying air in the drying assembly 40, and the drying air is discharged from the drying assembly 40 via the opening 421. In the present embodiment, the opening 421 is connected to an air outlet connection portion 61 of an air outlet duct 60 (see Figure 11 ) to be described later.

[0074] Also, as shown in Figure 8As shown, on the rear side of the drying assembly 40, there is also a recess 422 corresponding to a portion of the housing of the drying assembly 40 protruding forward for providing a main portion of the air outlet duct 60. The portion opposite to the opening 421 of the drying assembly 40 is used for providing the air outlet connecting portion 61 of the air outlet duct 60.

[0075] <Air inlet duct>

[0076] The air inlet duct 50 is used for guiding air in the laundry treatment drum (the first large drum 10, the first small drum 20, the second small drum 30, the second large drum 90) to the drying assembly 40. In Figure 9 and Figure 10 A perspective view of the air inlet duct 50 is shown in Figure 12 As shown, the air inlet duct 50 is configured such that at least a portion of the air inlet duct 50 extends from the rear side of at least any one of the first small drum 20 and the second small drum 30 in a lateral direction of the at least any one of the first small drum 20 and the second small drum 30 towards the front side, thereby saving the space for providing the air duct and further realizing miniaturization. Here, the lateral direction of the small drum can be any one of the up, down, left and right directions of the small drum, or the oblique lateral direction of the small drum. Figure 9 is a perspective view of the air inlet duct 50 observed from the front side (the opening side of the laundry treatment drum). As shown, Figure 9 the air inlet duct 50 has a first air inlet portion 51 formed towards the upper direction and opened upward in the upper portion, and a second air inlet portion 54 formed towards the lower direction and opened rearward in the lower portion. By forming the first air inlet portion 51 towards the upper direction, the path from the first large drum 10 to the air inlet duct 50 can be made shorter, so that the air in the laundry treatment drum can easily enter the drying assembly, reducing the air resistance. By forming the second air inlet portion 54 towards the lower direction, the path from the second large drum 90 to the air inlet duct 50 can be made shorter, so that the air in the laundry treatment drum can easily enter the drying assembly, reducing the air resistance. Between the first air inlet portion 51 and the second air inlet portion 54 in the up-down direction, there is a main portion in communication with the first air inlet portion 51 and the second air inlet portion 54, which has a bending portion 56 and a bending portion 57 at a position between the first small drum 20 and the second small drum 30, and the bending portion 56 and the bending portion 57 are bent along a portion of the outer circumferential surface of the drum body of the first small drum 20 and the second small drum 30.

[0077] The air inlet duct 50 is capable of making full use of the space between the first small cylinder 20 and the second small cylinder 30, which are cylindrical members, for the air guidance. The space between the two cylinders is such that the space above the two small cylinders is wide, and the space continuously narrows as it goes downward, the space becomes the narrowest at the line connecting the centers of the cylindrical shapes of the two small cylinders, and then the space continuously widens as it further goes downward, and the space below the two small cylinders becomes wide, approximately the same as the space above the two small cylinders.

[0078] The air inlet duct 50 has a shape that matches the cylindrical shapes of the first small cylinder 20 and the second small cylinder 30, and is capable of making full use of the space between the two small cylinders as an air guidance passage.

[0079] Specifically, the air inlet duct 50 has a curved portion 56 on the side opposite to the first small cylinder 20 in the left-right direction, and has a curved portion 57 on the side opposite to the second small cylinder 30 in the left-right direction, that is, the air inlet duct 50 has a shape that matches the first small cylinder 20 and the second small cylinder 30 between the first small cylinder 20 and the second small cylinder 30, and thus partially surrounds the first small cylinder 20 and the second small cylinder 30. By the curved portions 56, 57, it is possible to further effectively use the space of the peripheral structure of the small cylinders, and even the external space of the circular arc shape of the peripheral portion of the cylinder can be used as the setting space of the duct.

[0080] As shown in Figure 9 , the curved portion 56 has a curvature radius that is approximately the same as the curvature radius of the cylindrical shape of the first small cylinder 20, and the curved portion 56 extends downward from a position approximately above the first small cylinder 20 along the outer periphery of the cylindrical shape of the first small cylinder 20, and extends downward in a curved manner to a position below the position where the center axis of the cylindrical shape of the first small cylinder 20 is located (refer to the imaginary line K in Figure 1 ), thereby the curved portion 56 partially surrounds the outer periphery of the first small cylinder 20 in the circumferential direction of the cylindrical shape of the first small cylinder 20, for example, in the range of 90° to 150°.

[0081] As shown in Figure 9 , the curved portion 57 has a curvature radius that is approximately the same as the curvature radius of the cylindrical shape of the second small cylinder 30, and the curved portion 57 extends downward from a position approximately above the second small cylinder 30 along the outer periphery of the cylindrical shape of the second small cylinder 30, and extends downward in a curved manner to a position below the position where the center axis of the cylindrical shape of the second small cylinder 30 is located (refer to the imaginary line K in Figure 1The curved portion 57 extends to a position below the imaginary connecting line K in the figure, further surrounds the second small cylinder 30, and extends to a position substantially directly below the second small cylinder 30. The curved portion 57 then extends horizontally to a position between the second small cylinder 30 and the housing assembly 1. Thus, in the circumferential direction of the cylindrical shape of the second small cylinder 30, the curved portion 57 partially surrounds the outer periphery of the second small cylinder 30 within an angular range of, for example, 180° to 210°.

[0082] There is no particular limitation on the extension length of the curved portions 56 and 57 as long as they can be located between the first small tube 20 and the second small tube 30 in the left-right direction, thereby utilizing the space around the first small tube 20 and the second small tube 30 as an air guide channel. Figure 9 In the embodiment, the main body portion where the bent portions 56 and 57 are formed has a shape in which a "T-shape of the upper left English letter" and a "reversed L-shape of the lower right English letter" are connected, for example.

[0083] exist Figure 10 FIG. 5 shows a three-dimensional view of the air inlet duct 50 from another perspective. Figure 10 This is a three-dimensional view of the air inlet duct 50 viewed from the rear side (the side where the drying assembly 40 is located). Figure 10 As shown, the air inlet duct 50 has an air inlet connection portion 55 protruding and extending toward the rear side, and the air inlet connection portion 55 is connected to the opening 411 of the drying component 40 facing the front. The direction in which the air inlet duct 50 guides air to the drying component 40 is shown by the arrow at the air inlet connection portion 55 in the figure. Thus, the air in the air inlet duct 50 can be guided into the drying component 40 through the air inlet connection portion 55. The air inlet directions of the first air inlet portion 51 and the second air inlet portion 54 are shown in FIG. Figure 10 As shown by the arrows at each air inlet portion.

[0084] In addition, if Figure 10 As shown, similar to the structure of the curved portion 56 and the curved portion 57, the air inlet connecting portion 55 of the air inlet duct 50 also has a shape that matches the cylindrical shape of the first small cylinder 20 and the second small cylinder 30. Therefore, not only will the curved portion 56 and the curved portion 57 of the air inlet duct 50 not interfere with the first small cylinder 20 and the second small cylinder 30, but the air inlet connecting portion 55 of the air inlet duct 50 can also fully utilize the space around the small cylinders to transmit the drying gas without interfering with the first small cylinder 20 and the second small cylinder 30. Figure 10As shown, a triangular supporting member 58 is also provided on the lower side of the air inlet connection portion 55. The thickness (dimension in the left-right direction) of the supporting member 58 is relatively thin, and it can appropriately exist in the space between the first small cylinder 20 and the second small cylinder 30. The supporting member 58 based on such a structure can reliably support the overall structure of the air inlet duct 50, especially the air inlet connection portion 55, thereby increasing the area of ​​the drying air section for the first small cylinder 20 and the second small cylinder 30, and increasing the cross-sectional area (the area perpendicular to the direction of gas flow) of the air inlet connection portion 55. In addition, since the thickness of the supporting member 58 is relatively thin, the space around the first small cylinder 20 and the second small cylinder 30 can be fully utilized to ensure the cross-sectional area (the area perpendicular to the axis of rotation) of the first small cylinder 20 and the second small cylinder 30, thereby ensuring the overall air inlet area.

[0085] like Figure 9 、 Figure 10 As shown, the first air inlet portion 51 is, for example, a portion that protrudes upward from the main body and opens upward. The first air inlet portion 51 is connected to the first large cylinder 10, thereby guiding the air inside the first large cylinder 10 into the air inlet duct 50. The air inlet duct 50 also has other air inlets that are connected to the first small cylinder 20 and the second small cylinder 30, and the illustration and description are omitted here. The second air inlet portion 54 is, for example, a portion that is located at the lower part of the main body and opens toward the rear from the main body. The second air inlet portion 54 is connected to the second large cylinder 90, thereby guiding the air inside the second large cylinder 90 into the air inlet duct 50.

[0086] <Air outlet duct>

[0087] The air outlet duct 60 is used to send the dry air heated by the drying component 40 to the clothes processing drum (the first large drum 10, the first small drum 20, the second small drum 30, and the second large drum 90). Figure 11 , a perspective view of the air outlet duct 60 is shown as viewed from the front side. Figure 11 As shown, the air outlet duct 60 has an air outlet connection portion 61 whose dimensions in the front-to-back direction and the up-down direction are greater than its dimension in the left-to-right direction. The air outlet connection portion 61 is connected to the drying assembly 40, and the air in the drying assembly 40 flows into the air outlet duct 60 through the air outlet connection portion 61. Since the air outlet connection portion 61 is configured in a manner such that its main surface direction faces the left-to-right direction, even if the drying assembly 40 occupies most of the space behind the first small cylinder 20 and the second small cylinder 30, the air outlet connection portion 61 can be configured to be aligned with the drying assembly 40 in the left-to-right direction. In this way, the space behind the first small cylinder 20 and the second small cylinder 30 can be further fully utilized.

[0088] Likewise Figure 11As shown, the air outlet duct 60 also has a main body portion with the vertical direction as the longitudinal direction (i.e., the vertical dimension is the longest). The size of the main body portion in the front-to-back direction is smaller than the size in the left-to-right direction, and the size of the main body portion in the left-to-right direction is smaller than the size in the top-to-bottom direction. The reason for setting the size of the main body portion in the front-to-back direction to be smaller is that after the drying assembly 40 is set on the rear side of the first small cylinder 20 and the second small cylinder 30, the space remaining between the drying assembly 40 and the box assembly 1 is small. If the main body portion is larger in the front-to-back direction, the main body portion cannot be set in the recess 422 of the drying assembly 40. In addition, since the first large cylinder 10 and the second large cylinder 90 are larger in size, the space between the two large cylinders and the box assembly 1 is also small. Therefore, the front-to-back dimension of the main body portion is also smaller in order to be set on the rear side of the first large cylinder 10 and the rear side of the second large cylinder 90. The main body portion has a first air outlet portion 62 formed upward and open to the front at the upper portion near the upper side, and a second air outlet portion 63 formed downward and open to the front at the lower portion near the lower side. By forming the first air outlet portion 62 facing upward, the path from the air outlet duct 60 to the first large drum 10 can be shortened, so that the air in the drying component 40 can easily enter the clothing processing drum, reducing wind resistance. By forming the second air outlet portion 63 facing downward, the path from the air outlet duct 60 to the second large drum 90 can be shortened, so that the air in the drying component 40 can easily enter the clothing processing drum, reducing wind resistance.

[0089] Combine Figure 6 and Figure 11 , the configuration position of the air outlet duct 60 is described, such as Figure 6 As shown, the air outlet connection portion 61 of the air outlet duct 60 is aligned with the drying assembly 40 in the left-right direction and is in communication with the drying assembly 40. The main body of the air outlet duct 60 is formed at the rear side of the air outlet connection portion 61 and the drying assembly 40. The portion of the main body formed with the first air outlet portion 62 extends upward to the rear side of the first large cylinder 10 and is in communication with the first large cylinder 10. The portion of the main body formed with the second air outlet portion 63 extends downward to the rear side of the second large cylinder 90 and is in communication with the second large cylinder 90. In addition, as shown in FIG. Figure 11 As shown, the air outlet duct 60 also has an opening 64 connected to the first small cylinder 20 and the second small cylinder 30. Through the opening 64, the air outlet duct 60 is connected to the first small cylinder 20 and the second small cylinder 30, thereby sending the gas heated in the drying component 40 to the first small cylinder 20 and the second small cylinder 30.

[0090] As described above, by making the air outlet duct 60 have the air outlet connecting portion 61 with a size shorter in the left-right direction than in the front-rear direction and the up-down direction, the space on the rear side of the first small drum 20 and the second small drum 30 not occupied by the drying assembly 40 can be utilized, and by making the air outlet duct 60 have the main body portion with a size shorter in the front-rear direction than in the left-right direction and the up-down direction, the rear side space of the drying assembly 40 (the space at the recess 422), the rear side space of the first large drum 10, and the rear side space of the second large drum 90 can be utilized.

[0091] As described above, by making the air outlet connecting portion 61 communicate with the drying assembly 40, making the first air outlet portion 62 communicate with the first large drum 10, and making the second air outlet portion 63 communicate with the second large drum 90, the drying gas generated in the drying assembly 40 can be circulated and circulated.

[0092] Taking the drying of the clothes in the first large drum 10 as an example, the air inside the first large drum 10 is guided from the first large drum 10 to the air inlet duct 50 via the first air inlet portion 51, and then guided to the drying assembly 40 via the air inlet connecting portion 55 and the opening 411, heated in the drying assembly 40 to generate drying gas, and then enters the air outlet duct 60 via the air outlet connecting portion 61 of the air outlet duct 60 and the opening 421 of the drying assembly 40, and then circulates inside the air outlet duct 60 to the first air outlet portion 62, and then enters the first large drum 10 via the first air outlet portion 62, thereby realizing the circulation of the gas between the first large drum 10, the air inlet duct 50, the drying assembly 40, the air outlet duct 60, and the first large drum 10. The same applies to the drying of the clothes in the first small drum 20, the second small drum 30, and the second large drum 90, and the circulation of the gas between the drying assembly 40 and the first small drum 20 (or the second small drum 30, the second large drum 90) is realized via different air outlet portions.

[0093] <Effects>

[0094] In Figure 12 a top view taken at a position between the first large drum 10 and the first small drum 20 and the second small drum 30 is shown. As Figure 12 shown, the air inlet connecting portion 55 and the first air inlet portion 51 of the air inlet duct 50 are formed on the upper side of the space between the first small drum 20 and the second small drum 30, and the air inlet duct 50 also has a shape that cooperates with the first small drum 20 and the second small drum 30, and can pass through the narrow space between the first small drum 20 and the second small drum 30 to transmit the gas to the lower side of the space between the first small drum 20 and the second small drum 30, thereby enabling the transmission of drying gas to the second large drum 90 located below.

[0095] As described above, since at least a part of the air inlet duct 50 is located between the first small drum 20 and the second small drum 30, the space between the two cylindrical shapes of the first small drum 20 and the second small drum 30 can be utilized, the delivery of drying gas for multiple laundry treatment drums can be performed without occupying additional space to set the air inlet duct, the air supply duct setting space can be saved, the compactness of the configuration of each component in the multi-drum laundry treatment device is achieved, and miniaturization is achieved. Moreover, the drying assembly 40 is located at any one of the rear side, the upper side, and the lower side of the first small drum 20 and the second small drum 30. Corresponding to the structure of setting the air inlet duct 50 by utilizing the small drum peripheral space, the drying assembly 40 is relatively close to each drum body, not only achieving miniaturization, but also improving the drying effect, especially improving the drying effect for small drums, which is beneficial to using the drying assembly to provide drying gas for each laundry treatment drum, improves the utilization of space, and especially reduces the height of the multi-drum laundry treatment device when the drying assembly 40 is located at the rear side of the first small drum 20 and the second small drum 30.

[0096] In addition, the multi-drum laundry treatment device 100 adopting the present application can fully utilize the space around the laundry treatment drum in the cabinet assembly 1, as Figure 12 indicated, the drying assembly 40 is arranged at the rear side of the first small drum 20 and the second small drum 30, and the drying assembly 40 almost covers most of the space between the rear side of the first small drum 20 and the second small drum 30 and the cabinet assembly 1, so that the size of the drying assembly 40 can be fully ensured, and the drying assembly 40 can generate sufficient drying gas to meet the drying demand of multiple laundry treatment drums.

[0097] In addition, as Figure 12 indicated, even if a large enough drying assembly 40 is arranged, the remaining part of the space between the rear side of the first small drum 20 and the second small drum 30 and the cabinet assembly 1 can still be utilized to arrange at least a part (for example, the air outlet connecting part 61) of the air outlet duct 60. Moreover, at least a part of the main part of the air outlet duct 60 is arranged at the recessed part at the rear side of the drying assembly 40. Thus, in terms of the space where the first small drum 20 and the second small drum 30 are located, each component is arranged in a way that there is almost no wasted space. The compact structure is greatly achieved, and further miniaturization is achieved.

[0098] <Other structures and variants of the present application>

[0099] (1) In Figure 1In the present embodiment, the imaginary line K connecting the center of the circle of the first small drum 20 and the center of the circle of the second small drum 30 is shown, and the center of the circle of the first small drum 20 and the center of the circle of the second small drum 30 referred to in the present specification mean the center of the circle of the first small drum 20 and the center of the circle of the second small drum 30 as viewed in the front direction of the multi-drum laundry treating apparatus. Preferably, the imaginary line K is inclined at an angle of 0 to 15 degrees with respect to the horizontal plane, and more preferably, the imaginary line K is parallel to the horizontal plane.

[0100] (2) In the multi-drum laundry treating apparatus of the present application, only one large drum, i.e., either the first large drum 10 or the second large drum 90 can be provided. Further, the small drums of the present application are not limited to the two small drums, i.e., the first small drum 20 and the second small drum 30, but can be provided in a number greater than two. In the case where more than two small drums are provided, for example, the more than two small drums can be arranged in the left-right direction between the first large drum 10 and the second large drum 90, and by providing the plurality of small drums, the laundry can be treated more efficiently, and the arrangement of the two small drums in the left-right direction can prevent the overall apparatus from being enlarged in the up-down direction. Alternatively, the more than two small drums can be arranged in two layers between the first large drum 10 and the second large drum 90, and in this case, the air inlet duct 50 can be provided in the peripheral space of any one of the small drums, and the space around the small drums can be efficiently utilized. For example, at least a portion of the air inlet duct 50 can be provided in the left-right direction between adjacent two of the more than two small drums, or between one of the small drums adjacent to the cabinet assembly 1 and the cabinet assembly 1, and thereby, the space between the two small drums in the peripheral structure of the small drums or the space between the small drums and the cabinet assembly can be efficiently utilized.

[0101] (3) The drying assembly 40 can be provided not only at the rear side of the first small drum 20 and the second small drum 30, but also at the upper side or the lower side of the first small drum 20 and the second small drum 30. If the drying assembly 40 is provided at the upper side or the lower side, the depth of the first small drum 20 and the second small drum 30 can be appropriately increased, and the capacity of the first small drum 20 and the second small drum 30 can be increased, and in this case, the air inlet duct 50 can be provided using the space around the first small drum 20 and the second small drum 30.

[0102] (4) In the case of the air inlet duct 50, it can be provided not only between the first small drum 20 and the second small drum 30, but also in the left-right direction at the side of the drum body of any one of the first small drum 20 and the second small drum 30, i.e., between the first small drum 20 and the cabinet assembly 1 or between the second small drum 30 and the cabinet assembly 1.

[0103] (5) The air inlet duct 50 can be connected to at least one of the first large drum 10, the first small drum 20, and the second small drum 30 and the second large drum 90, and guides the air inside at least one of the first large drum 10, the first small drum 20, and the second small drum 30 and the second large drum 90 into the drying assembly 40.

[0104] (6) The air outlet portion (the first air outlet portion 62, the second air outlet portion 63, and other air outlet portions not shown) of the air outlet duct is connected to at least one of the first large drum 10, the first small drum 20, the second small drum 30, and the second large drum 90 from the rear, and the air inside the air outlet duct 60 flows into at least one of the first large drum 10, the first small drum 20, the second small drum 30, and the second large drum 90 via the air outlet portion, whereby not only the drying gas can be circulated between the laundry treatment drum and the drying assembly 40 based on the air inlet duct 50 and the air outlet duct 60 to continuously dry the laundry, but also the space behind the laundry treatment drum can be fully utilized by connecting the air outlet portion to the laundry treatment drum from the rear.

[0105] (7) The curved portions 56 and 57 can have only one or both. In addition, the curved portions 56 and 57 are not limited to being opposite to the side surfaces in the left-right direction of the small drum, i.e., not limited to being along the outer circumferential surfaces of the left and right sides of the drum body of the small drum, but can be opposite to the side surfaces in the up-down direction of the small drum or opposite to the diagonal side surfaces of the small drum.

[0106] (8) The orientations (open directions) of the openings of the first air inlet portion 51 and the second air inlet portion 54 described above are not particularly limited as long as the circulation of the gas can be satisfied.

[0107] (9) The air duct fan 70 for flowing the air is provided in at least one of the air inlet duct 50 and the air outlet duct 60, and the circulation of the drying gas in the air duct can be facilitated by providing the air duct fan 70 in at least one of the air inlet duct 50 and the air outlet duct 60. Figure 12 In the drawing, the housing of the air outlet duct 60 is omitted, and thus the air duct fan 70 provided inside the air outlet duct 60 is shown. For example, the air duct fan 70 for flowing the air is provided in the air outlet connection portion 61, and the air duct fan 70 is provided to the side of the drying assembly 40 in the left-right direction, and the rotational axis thereof extends in the left-right direction. By providing the air duct fan 70 to the side of the drying assembly 40, not only the circulation of the drying gas in the air duct can be facilitated, but also the space to the side of the drying assembly 40 can be effectively utilized, and further miniaturization can be facilitated.

[0108] (10) A cooling fan 46 is arranged on the rear side of the drying assembly 40, and a cooling fan 46 can also be arranged on one of the left and right sides of the drying assembly 40.

[0109] (11) The multi-cylinder clothes treatment device 100 further comprises a switching part arranged in at least one of the air inlet duct 50 and the air outlet duct 60, for controlling the opening and closing and / or the air volume of the air duct. By having the switching part, the opening and closing and / or the air volume of the air duct can be controlled.

[0110] (12) A fragrance is arranged in at least one of the air inlet duct 50 and the air outlet duct 60, so that the gas for drying the clothes has a fragrance that can be attached to the clothes, bringing a better experience to the user.

[0111] (13) The filter screen assembly is arranged in the air inlet duct 50, and the air introduced into the air inlet duct 50 is guided to the drying assembly 40 after being filtered by the filter screen assembly. The lint such as threads or fluff contained in the drying gas can be filtered by the filter screen assembly. In addition, the air inlet duct 50 is fixed to at least any one of the drying assembly 40, the cabinet assembly 1, and the two or more small cylinders. It should be noted that the air inlet duct 50 can be fixed to two or more small cylinders at the same time, or only one of them. By fixing the air inlet duct 50, the vibration that may occur when the drying gas flows in the air inlet duct 50 can be inhibited. By arranging the air inlet duct 50 between the two small cylinders and rigidly connecting the air inlet duct 50 with the two small cylinders, the two small cylinders can be fixed by the air inlet duct 50 to form a counterweight to each other to inhibit the vibration generated when the small cylinders rotate. In addition, when the number of small cylinders is more than two, a plurality of air inlet ducts 50 can be correspondingly provided. The plurality of air inlet ducts 50 can be arranged between two adjacent small cylinders in the plurality of small cylinders, thereby also achieving the effect of inhibiting the vibration generated when the plurality of small cylinders rotate. The rigid connection manner is not limited, for example, a connecting portion can be additionally arranged at a non-air inlet connection position outside the shell of the air inlet duct 50. Preferably, at least any one of the first air inlet portion 51 and the second air inlet portion 54 (also including the air inlet portion communicated with the small cylinder) is connected to the clothes treatment cavity of at least one of the first large cylinder 10, the two or more small cylinders (including but not limited to the first small cylinder 20 and the second small cylinder 30), and the second large cylinder 90 by elastic connection of the elastic buffer or rigid connection. The air inlet connection portion 55 is connected to the drying assembly 40 by elastic connection of the elastic buffer or rigid connection. By elastic connection of the elastic buffer or rigid connection, the air inlet portion (the first air inlet portion 51, the second air inlet portion 54, and the air inlet portion communicated with the small cylinder) and the clothes treatment cavity are connected, and the air inlet connection portion 55 and the drying assembly 40 are connected. The elastic buffer can be used to absorb the vibration that may occur at the connection position, further improve the effect of absorbing vibration, or in the case of a drying machine cylinder or when the air inlet portion is not fixed to the clothes treatment cylinder that vibrates, the connection structure can be simplified by rigid connection. Similarly, for the air outlet duct 60, the air outlet portion (the first air outlet portion 62, the second air outlet portion 63, and other air outlet portions not shown) can be connected to the clothes treatment cavity of at least one of the first large cylinder 10, the two or more small cylinders (including but not limited to the first small cylinder 20 and the second small cylinder 30), and the second large cylinder 90 by elastic connection of the elastic buffer or rigid connection.
