Description

Technical Field

[0001] The utility model relates to a multi-drum clothing processing device. Background Art

[0002] With the advancement of technology in the washing machine industry and the improvement of people's awareness of cleaning, consumers are paying more and more attention to the healthy washing of washing machines, especially for mothers and babies. Consumers gradually begin to want to wash underwear, socks, and large categories of clothing separately. The demand for partitioned cleaning of small underwear / baby clothes by mothers and babies is also increasing, so multi-drum washing machines are needed for partitioned cleaning. However, the upper and lower double-zone washing / drying machines or single mini washing machines currently on the market can only separate one piece of underwear / underwear / socks or baby clothes from other clothes. When multiple sensitive clothes need to be processed in zones, they still need to be put in order multiple times, affecting housework efficiency. At the same time, due to space limitations, the existing mini washing machines have weak drying effects.

[0003] In the existing multi-drum clothing processing device, in order to dry the clothes in the clothing processing drum, an air duct is provided in connection with the clothing processing drum. However, the clothing processing drum in the prior art occupies a relatively large space. In addition, due to the shape of the clothing processing drum itself, it is difficult to compactly arrange the air duct and the clothing processing drum in the prior art of providing the air duct for the clothing processing drum. As a result, the air duct occupies an additional relatively large space, which leads to the problem of the overall large-scale device. Utility Model Content

[0059] 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.

[0060] <Overall structure of multi-drum laundry processing device>

[0061] like Figure 1 to Figure 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.

[0062] exist Figure 1, a front view of the appearance of a multi-drum laundry processing device 100 is shown, 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, the outer contour of the multi-drum laundry processing device 100 is constituted, and a cavity space is formed 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 the first large drum 10 and the second large drum 90 described later, both of which are arranged below the first large drum 10, and are arranged in the box assembly 1 along the left-right direction, 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 of the cavity space, and in the up-down direction, the second large drum 90 is relatively The first small cylinder 20 and the second small cylinder 30 are arranged on the opposite side of the first large cylinder 10, so that the first small cylinder 20 and the second small cylinder 30 are located between the first large cylinder 10 and the second large cylinder 90 in the cavity space, and the outer diameters of the first small cylinder 20 and the second small cylinder 30 are also smaller than the second large cylinder 90. In addition, the first small cylinder 20 and the second small cylinder 30 can also be arranged above the first large cylinder 10. In this case, the first small cylinder 20 and the second small cylinder 30 are arranged below the second large cylinder 90.

[0063] exist Figure 2 , Figure 3 FIG. 4 shows a stereoscopic view after omitting the box assembly 1. 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.

[0064] <Peripheral Structure of Clothes Processing Tub>

[0065] 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. Therefore, 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, special occupations, and other factors). On the other hand, the cylindrical clothing processing drum has also become a cause of large-scale. Unlike a shape such as a cube, a cylindrical shape usually has the defect that the surrounding space is difficult to effectively utilize. In view of this point, the inventors of the present application have effectively utilized the surrounding space of the clothing processing drum, so that the multi-drum clothing processing device of the present application can be more compactly constructed to achieve miniaturization.

[0066] The peripheral space of the clothing processing drum includes, for example, the space between two small drums, the rear side of two small drums, the upper side of two small drums, the lower side of two small drums, the rear side of 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).

[0067] 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 Detailed description is given in FIG. 3 , in which the peripheral structure of the laundry processing drum of the present application is shown 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.

[0068] like Figure 4 As shown, the air inlet duct 50 of the present application is constructed as follows: in the left-right direction, at least a portion of the air inlet duct 50 is sandwiched between the first small tube 20 and the second small tube 30, or in the left-right direction, at least a portion of the air inlet duct 50 is sandwiched between at least one of the first small tube 20 and the second small tube 30 and the box assembly 1 (for example, at least a portion of the air inlet duct 50 is sandwiched between the first small tube 20 and the box assembly 1 on the left side of the first small tube 20, and / or at least a portion of the air inlet duct 50 is sandwiched between the second small tube 30 and the box assembly 1 on the right side of the second small tube 30). In this way, the space between the first small tube 20 and the second small tube 30 can be used as a channel for gas circulation. Figure 5 As shown, an air outlet connection portion 61 serving as a part of the air outlet duct 60 is provided on the rear side of the first small tube 20 .

[0069] exist Figure 6 In the figure, the first small cylinder 20 and the second small cylinder 30 are removed. Figure 6It can be seen that a drying assembly 40 is provided at the rear side of the first small cylinder 20 and the second small cylinder 30. The drying assembly 40 is provided between the first large cylinder 10 and the second large cylinder 90 in the up-down direction. The drying assembly 40 occupies most of the space at the rear side of the first small cylinder 20 and the second small cylinder 30, and the air outlet connection portion 61 as a part of the air outlet duct 60 occupies a small part of the space at the rear side of the first small cylinder 20 and the second small cylinder 30. The air outlet connection portion 61 of the drying assembly 40 and the air outlet duct 60 is arranged and connected in the left-right direction. Thus, the space at the rear side of the first small cylinder 20 and the second small cylinder 30 can be fully utilized, and in the horizontal direction of the space where the first small cylinder 20 and the second small cylinder 30 are located, the first small cylinder 20, the second small cylinder 30, the drying assembly 40, at least a part of the air inlet duct 50, and at least a part of the air outlet duct 60 are provided at the same time, thereby realizing a compact layout of the peripheral structure of the clothing processing cylinder.

[0070] The following is based on Figure 7 to Figure 11 , the structures of the drying component 40, the air inlet duct 50, and the air outlet duct 60 are described.

[0071] <Drying Components>

[0072] The drying component 40 is used to heat the air to generate drying air. Figure 7 As shown, the drying assembly 40 has an upper shell 41 and a lower shell 42, and the upper shell 41 and the lower shell 42 are engaged with each other, so that components such as a compressor, an evaporator, and a condenser (not shown) are accommodated inside the drying assembly 40. Of course, the compressor is not necessarily arranged inside the drying assembly 40, and a structure for installing the compressor can also be arranged on the lower shell 42 without the upper shell engaging and covering.

[0073] An opening 411 is provided at the front portion of the drying assembly 40 in the front-to-back direction, that is, at the wall portion opposite to the first small cylinder 20 and the second small cylinder 30 in the front-to-back direction. Figure 7 In the example shown, the opening 411 is formed in the upper shell 41, but it can also be formed in the lower shell 42, which is not limited to this. Figure 7 As shown by the arrow in FIG. 1 , the air from the laundry processing drum (large drum and / or small drum) is guided to the drying assembly 40, where the air is heated to generate drying air. In this embodiment, the opening 411 is connected to the air inlet connection portion 55 of the air inlet duct 50 described later (see FIG. Fig.10 ), thereby enabling air to be delivered to the drying component 40.

[0074] exist Figure 8 , a stereoscopic view of the drying assembly 40 is shown from the rear side (the side opposite to the first small cylinder 20 and the second small cylinder 30). Figure 8The driving unit 80 is omitted in the figure. The upper part of the housing of the drying component 40 has a mounting portion, and the driving unit 80 can be arranged on the mounting portion of the upper part of the housing of the drying component 40, and is used to drive the rotation of the rotating drum in the first large drum 10. By using the upper part of the housing of the drying component 40 as the mounting portion for mounting the driving unit 80, there is no need to set up a separate mounting portion for mounting the driving unit 80, and miniaturization in the vertical direction can also be achieved. More preferably, the mounting portion is set as a groove 412, such as Figure 8 As shown, the upper portion of the upper housing 41 facing upward has a groove 412, and the groove 412 is used to install the driving unit 80. Figure 7 4 shows a structure in which the driving unit 80 is installed in the groove 412. By providing a groove on the drying assembly 40 to install the driving unit 80, it can be further miniaturized in the vertical direction.

[0075] In addition, Figure 8 4 shows that the lower housing 42 has an opening 421, and the opening 421 is used to send out the dry gas generated in the drying assembly 40, that is, the air in the clothes processing drum is guided to the drying assembly 40 through the opening 411, the air is heated into dry gas in the drying assembly 40, and then the dry gas is sent out from the drying assembly 40 through the opening 421. In this embodiment, the opening 421 is connected to the outlet connection portion 61 of the outlet duct 60 described later (refer to Fig.11 ).

[0076] And, if Figure 8 As shown, there is a recess 422 at the rear side of the drying component 40, which is equivalent to the part of the housing of the drying component 40 protruding forward, and this part is used to set the main part of the air outlet duct 60. The part opposite to the opening 421 of the drying component 40 is used to set the air outlet connection part 61 of the air outlet duct 60.

[0077] <Air inlet duct>

[0078] The air inlet duct 50 is used to guide the air in the laundry processing drum (the first large drum 10, the first small drum 20, the second small drum 30, and the second large drum 90) to the drying assembly 40. Fig. 9 and Fig.10 FIG. 5 shows a three-dimensional view of the air inlet duct 50. Fig.12 As shown, the air inlet duct 50 is configured as follows: at least a portion of the air inlet duct 50 extends from the rear side of at least one of the first small tube 20 and the second small tube 30 toward the front side at the side of the at least one small tube along the front-to-back direction, thereby saving the installation space of the air duct and realizing miniaturization. Here, the side of the small tube can be any side of the small tube, up, down, left, right, or oblique side of the small tube. Fig. 9 This is a three-dimensional view of the air inlet duct 50 viewed from the front side (the opening side of the laundry treatment drum). Fig. 9 As shown, the air inlet duct 50 has a first air inlet portion 51 formed upward and opened upward at the upper part, and has a second air inlet portion 54 formed downward and opened rearward at the lower part. By forming the first air inlet portion 51 facing upward, the path from the first large drum 10 to the air inlet duct 50 can be shortened, so that the air in the clothing processing drum can easily enter the drying component and reduce wind resistance. By forming the second air inlet portion 54 facing downward, the path from the second large drum 90 to the air inlet duct 50 can be shortened, so that the air in the clothing processing drum can easily enter the drying component and reduce wind resistance. In the up and down direction, there is a main body portion connected to the first air inlet portion 51 and the second air inlet portion 54 between the first air inlet portion 51 and the second air inlet portion 54, and the main body portion has a bending portion 56 and a bending portion 57 at a position between the first small cylinder 20 and the second small cylinder 30, and the bending portion 56 and the bending portion 57 are local bends along the outer peripheral surface of the cylinder body of the first small cylinder 20 and the second small cylinder 30.

[0079] The air inlet duct 50 can make full use of the space between the first small cylinder 20 and the second small cylinder 30 to guide the air. The first small cylinder 20 and the second small cylinder 30 are cylindrical components. The space between the first small cylinder 20 and the second small cylinder 30 is as follows: the space above the two small cylinders is wider, and as it goes downward, the space continuously narrows. At the line connecting the centers of the cylindrical shapes of the two small cylinders, the space becomes the narrowest. Then, as it goes further downward, the space continuously widens. The space below the two small cylinders becomes wider, which is roughly the same as the space above the two small cylinders.

[0080] Regarding the space between the two small tubes, the air inlet duct 50 has a shape that matches the cylindrical shapes of the first small tube 20 and the second small tube 30, and can utilize the space between the two small tubes as an air guide channel.

[0081] Specifically, the air inlet duct 50 has a curved portion 56 on the side opposite to the first small tube 20 in the left-right direction, and has a curved portion 57 on the side opposite to the second small tube 30 in the left-right direction, that is, the air inlet duct 50 has a shape matching the first small tube 20 and the second small tube 30 between the first small tube 20 and the second small tube 30, thereby partially surrounding the first small tube 20 and the second small tube 30. Through the curved portions 56 and 57, the space of the peripheral structure of the small tube can be further effectively utilized, and even the arc-shaped external space around the cylinder body can be utilized as the setting space of the air duct.

[0082] like Fig. 9As shown, the curved portion 56 has a curvature radius that is substantially the same as the curvature radius of the cylindrical shape of the first small cylinder 20. The curved portion 56 extends downward along the outer circumference of the cylindrical shape of the first small cylinder 20 from a position substantially directly above the first small cylinder 20 to a position that is slightly lower than the central axis of the cylindrical shape of the first small cylinder 20 (see Figure 1 The curved portion 56 partially surrounds the outer periphery of the first small tube 20 in the circumferential direction of the cylindrical shape of the first small tube 20, for example, within an angle range of 90° to 150°.

[0083] like Fig. 9 As shown, the curved portion 57 has a curvature radius that is substantially the same as the curvature radius of the cylindrical shape of the second small cylinder 30. The curved portion 57 extends downward along the outer circumference of the cylindrical shape of the second small cylinder 30 from a position substantially directly above the second small cylinder 30 to a position that is slightly lower than the central axis of the cylindrical shape of the second small cylinder 30 (see Figure 1 The curved portion 57 extends to a position below the imaginary line K in the second cylinder 30 and further surrounds the second cylinder 30 to a position substantially directly below the second cylinder 30, and then extends horizontally to a position between the second cylinder 30 and the box assembly 1. Thus, in the circumferential direction of the cylindrical shape of the second cylinder 30, the curved portion 57 partially surrounds the outer periphery of the second cylinder 30, for example, within an angle range of 180° to 210°.

[0084] 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. Fig. 9 In the embodiment, the main body portion where the bent portions 56 and 57 are formed is in a shape in which, for example, a "T-shape at the upper left" and an "inverted L-shape at the lower right" are connected.

[0085] exist Fig.10 FIG. 4 shows a three-dimensional view of the air inlet duct 50 from another viewing angle. Fig.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). Fig.10 As shown in the figure, 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, thereby, the air in the air inlet duct 50 can be guided into the drying component 40 via 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. Fig.10 As shown by the arrows at each air inlet portion.

[0086] In addition, if Fig.10 As shown, similar to the structure of the curved portion 56 and the curved portion 57, the air inlet connection 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 connection 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. And as Fig.10 As 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 be appropriately present 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, increasing the cross-sectional area (the area perpendicular to the gas flow direction) of the air inlet connection portion 55, and, because 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 rotation axis) of the first small cylinder 20 and the second small cylinder 30, thereby ensuring the overall air inlet area.

[0087] like Fig. 9 , Fig.10 As shown, the first air inlet 51 is, for example, a portion that protrudes upward from the main body and opens upward. The first air inlet 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 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, and the second air inlet 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.

[0088] <Air outlet duct>

[0089] The air outlet duct 60 is used to deliver the dry air heated by the drying assembly 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). Fig.11 , a perspective view of the air outlet duct 60 viewed from the front side is shown. Fig.11As 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 larger than the 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 that its main surface direction faces the left-to-right direction, even if the drying assembly 40 occupies most of the space on the rear side of the first small cylinder 20 and the second small cylinder 30, the air outlet connection portion 61 can be configured to be arranged in the left-to-right direction with the drying assembly 40. In this way, the space on the rear side of the first small cylinder 20 and the second small cylinder 30 can be further fully utilized.

[0090] Likewise Fig.11 As shown, the air outlet duct 60 also has a main body with the vertical direction as the length direction (i.e., the vertical direction is the longest), the size of the main body in the front-to-back direction is smaller than the size in the left-to-right direction, and the size of the main body in the left-to-right direction is smaller than the size in the vertical direction. The reason for setting the size of the main body in the front-to-back direction to be smaller is that after the drying assembly 40 is set at the rear side of the first small cylinder 20 and the second small cylinder 30, the remaining space between the drying assembly 40 and the box assembly 1 is smaller. If the main body has a larger size in the front-to-back direction, the main body cannot be set at the recess 422 of the drying assembly 40. In addition, since the size of the first large cylinder 10 and the second large cylinder 90 is larger, the space between the two large cylinders and the box assembly 1 is also smaller. Therefore, the front-to-back size of the main body is also smaller so that it can be set at the rear side of the first large cylinder 10 and the rear side of the second large cylinder 90. The main body has a first air outlet 62 formed upward and opened to the front at the upper part of the upper side, and the main body has a second air outlet 63 formed downward and opened to the front at the lower part of 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.

[0091] Combination Figure 6 and Fig.11 , the configuration position of the air outlet duct 60 is described, such as Figure 6As shown, the air outlet connection portion 61 of the air outlet duct 60 is arranged with the drying assembly 40 in the left-right direction and is connected 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 part 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 connected with the first large cylinder 10, and the part 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 connected with the second large cylinder 90. In addition, as shown in FIG. Fig.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 delivering the gas heated in the drying component 40 to the first small cylinder 20 and the second small cylinder 30.

[0092] As described above, by making the air outlet duct 60 have an air outlet connection portion 61 whose dimensions in the left-right direction are shorter than those in the front-to-back direction and the up-to-down direction, the space on the rear side of the first small cylinder 20 and the second small cylinder 30 that is not occupied by the drying component 40 can be utilized. By making the air outlet duct 60 have a main portion whose dimensions in the front-to-back direction are shorter than those in the left-to-right direction and the up-to-down direction, the rear space of the drying component 40 (the space at the recess 422), the rear space of the first large cylinder 10, and the rear space of the second large cylinder 90 can be utilized.

[0093] As described above, by connecting the air outlet connection portion 61 to the drying assembly 40, connecting the first air outlet portion 62 to the first large cylinder 10, and connecting the second air outlet portion 63 to the second large cylinder 90, the drying gas generated in the drying assembly 40 can be circulated.

[0094] Taking the drying of the clothes in the first drum 10 as an example, the air inside the first drum 10 is guided from the first drum 10 to the air inlet duct 50 via the first air inlet portion 51, and then guided to the drying component 40 via the air inlet connection portion 55 via the opening 411, and is heated in the drying component 40 to generate dry gas. Thereafter, the air enters the air outlet duct 60 through the opening 421 of the drying component 40 and the air outlet connection portion 61 of the air outlet duct 60. Then, the dry gas circulates inside the air outlet duct 60 to the first air outlet portion 62, and enters the first drum 10 via the first air outlet portion 62. Thus, the circulation of gas in the first drum 10, the air inlet duct 50, the drying component 40, the air outlet duct 60, and the first drum 10 is realized. The same is true for drying the clothes in the first small drum 20, the second small drum 30, and the second large drum 90. Through different air outlets, the gas is circulated between the drying component 40 and the first small drum 20 (or the second small drum 30, the second large drum 90).

[0095] <Effect>

[0096] exist Fig.12 , a top view of the first large cylinder 10 and a position between the first small cylinder 20 and the second small cylinder 30 is shown. Fig.12 As 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 cylinder 20 and the second small cylinder 30, and the air inlet duct 50 also has a shape that matches the first small cylinder 20 and the second small cylinder 30, and can pass through the narrow space between the first small cylinder 20 and the second small cylinder 30, and transmit the gas to the lower side of the space between the first small cylinder 20 and the second small cylinder 30. Therefore, even the second large cylinder 90 located below can be subjected to the transmission of drying gas thereto.

[0097] As described above, since at least a portion of the air inlet duct 50 is located between the first small cylinder 20 and the second small cylinder 30, the space between the two cylindrical shapes of the first small cylinder 20 and the second small cylinder 30 can be utilized, and the drying gas can be transported for multiple clothing processing cylinders without occupying other spaces to set the air inlet duct, which can save the space for setting the air supply duct, realize the compactness of the configuration of each component in the multi-cylinder clothing processing device, and realize miniaturization. In addition, the drying component 40 is arranged on any one of the rear side, upper side, and lower side of the first small cylinder 20 and the second small cylinder 30. Corresponding to the structure of using the space around the small cylinder to set the air inlet duct 50, the distance between the drying component 40 and each cylinder is relatively close, which not only realizes miniaturization, but also improves the drying effect, especially improves the drying effect for the small cylinder, facilitates the use of the drying component to provide drying gas for each clothing processing cylinder, and improves the utilization rate of space. When the drying component 40 is arranged on the rear side of the first small cylinder 20 and the second small cylinder 30, the height of the multi-cylinder clothing processing device is particularly reduced.

[0098] In addition, by using the multi-drum laundry processing device 100 of the present invention, the space around the laundry processing drum can be fully utilized in the box assembly 1. Fig.12 As shown, a drying assembly 40 is provided at the rear side of the first small cylinder 20 and the second small cylinder 30, and the drying assembly 40 almost covers most of the space between the rear side of the first small cylinder 20 and the second small cylinder 30 and the box assembly 1. Therefore, the size of the drying assembly 40 can be fully ensured, and it can be ensured that the drying assembly 40 can generate sufficient drying gas to meet the drying needs of multiple clothing processing cylinders.

[0099] In addition, if Fig.12As shown, even if a sufficiently large drying assembly 40 is provided, at least a portion of the air outlet duct 60 (for example, the air outlet connection portion 61) can still be provided by utilizing a portion of the remaining space between the rear side of the first small cylinder 20 and the second small cylinder 30 and the box assembly 1. At least a portion of the main body of the air outlet duct 60 is provided in the recessed portion on the rear side of the drying assembly 40. Thus, with respect to the space where the first small cylinder 20 and the second small cylinder 30 are located, the various components can be laid out in a manner where almost no space is wasted. This greatly achieves a compact structure, thereby achieving miniaturization.

[0100] <Other structures and modifications of the present application>

[0101] (1) Figure 1 In the figure, an imaginary line K connecting the center of the first small drum 20 and the center of the second small drum 30 is shown. The center of the first small drum 20 and the center of the second small drum 30 mentioned in this specification refer to the centers of the circles formed by the first small drum 20 and the second small drum 30 when the multi-drum laundry processing device is viewed from the front. Preferably, the imaginary line K is 0 to 15 degrees relative to the horizontal plane, and more preferably, the imaginary line K is parallel to the horizontal plane.

[0102] (2) In the multi-drum clothing processing device of the present invention, there may be only one large drum, that is, only the first large drum 10 or the second large drum 90. In addition, the small drum of the present invention is not limited to the first small drum 20 and the second small drum 30, and there may be more than two small drums. In the case of having more than two small drums, for example, two or more small drums may be arranged between the first large drum 10 and the second large drum 90 in the left-right direction. By having a plurality of small drums, more clothes can be processed, and the layout of the two small drums arranged in the left-right direction can suppress the overall enlargement of the device in the up-down direction. It is also possible to arrange the two or more small drums in two layers between the first large drum 10 and the second large drum 90. In this case, it is only necessary to set the air inlet duct 50 in the peripheral space of any one small drum to make full use of the space around the small drum. For example, at least a portion of the air inlet duct 50 is sandwiched between two adjacent small tubes among more than two small tubes in the left-right direction, or is arranged between a small tube adjacent to the box assembly 1 and the box assembly 1 in the left-right direction. Thus, the space between two small tubes in the peripheral structure of the small tube or the space between the small tube and the box assembly can be effectively utilized, and the air inlet duct 50 and the small tube are compactly arranged without the need for additional space for setting up the duct, thereby achieving miniaturization.

[0103] (3) In addition to being disposed on the rear side of the first small cylinder 20 and the second small cylinder 30, the drying component 40 can also be formed on the upper side or the lower side of the first small cylinder 20 and the second small cylinder 30. If the drying component 40 is disposed on the upper side or the lower side, the depth length of the first small cylinder 20 and the second small cylinder can be appropriately increased, and the capacity of the first small cylinder 20 and the second small cylinder can be increased. In this case, the air inlet duct 50 can also be disposed using the space around the first small cylinder 20 and the second small cylinder.

[0104] (4) For the air inlet duct 50 in any case, in addition to being able to be set between the first small cylinder 20 and the second small cylinder 30, it can also be set on the side of the cylinder body of either the first small cylinder 20 or the second small cylinder 30 in the left-right direction, that is, between the first small cylinder 20 and the box assembly 1 or between the second small cylinder 30 and the box assembly 1.

[0105] (5) The air inlet duct 50 can be connected to at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90, and guide the air inside at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90 into the drying component 40. The air outlet duct 60 can be connected to at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90 corresponding to the air inlet duct 50, and guide the air heated by the drying component 40 to at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90.

[0106] (6) The air outlet portion of the air outlet duct (the first air outlet portion 62, the second air outlet portion 63, and other air outlet portions not shown) is connected to at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90 from the rear, and the air in the air outlet duct 60 flows into at least one of the first large cylinder 10, the first small cylinder 20, the second small cylinder 30, and the second large cylinder 90 via the air outlet portion. As a result, not only can the drying gas circulate between the clothing processing drum and the drying component 40 based on the air inlet duct 50 and the air outlet duct 60 to continuously dry the clothing, but also the space behind the clothing processing drum can be fully utilized by connecting the air outlet portion to the clothing processing drum from the rear.

[0107] (7) There may be only one or both of the curved portions 56 and 57. In addition, the curved portions 56 and 57 are not limited to being opposite to the side surfaces of the small tube in the left-right direction, that is, they are not limited to being opposite to the outer peripheral surfaces along the left and right sides of the cylinder body of the small tube, but may also be opposite to the side surfaces of the small tube in the up-down direction, or to the oblique side surfaces of the small tube.

[0108] (8) The orientation (opening direction) of the openings of the first air inlet 51 and the second air inlet 54 described above is not particularly limited as long as the air circulation can be satisfied.

[0109] (9) A duct fan 70 for flowing air is provided in at least one of the air inlet duct 50 and the air outlet duct 60. By providing the duct fan 70 in at least one of the air inlet duct 50 and the air outlet duct 60, the circulation of the drying gas in the duct can be facilitated. Fig.12 In the figure, the housing of the air outlet duct 60 is omitted, and the duct fan 70 disposed in the air outlet duct 60 is shown. For example, the air outlet connection portion 61 is provided with the duct fan 70 for making the air flow, and the duct fan 70 is disposed on the side of the drying component 40 in the left-right direction, and its rotation axis extends in the left-right direction. By arranging the duct fan 70 on the side of the drying component 40, it can not only help the drying gas to circulate in the duct, but also effectively utilize the side space of the drying component 40, which is conducive to further miniaturization.

[0110] (10) The cooling fan 46 is provided on the rear side of the drying assembly 40 , and the cooling fan 46 may be provided on one of the left and right side surfaces of the drying assembly 40 .

[0111] (11) The multi-drum laundry processing device 100 further includes a switching unit, which is provided in at least one of the air inlet duct 50 and the air outlet duct 60, and is used to control the opening and closing of the air duct and / or the size of the air volume. By having the switching unit, the opening and closing of the air duct and / or the size of the air volume can be controlled.

[0112] (12) A fragrance is provided in at least one of the air inlet duct 50 and the air outlet duct 60 so that the gas used to dry the clothes has a fragrance, and the fragrance can adhere to the clothes, giving the user a better experience.

[0113] (13) A filter assembly is provided in the air inlet duct 50. The air introduced into the air inlet duct 50 is filtered by the filter assembly and then guided to the drying assembly 40. The filter assembly can filter out clothing threads, fluff and other thread debris contained in the drying gas. In addition, the air inlet duct 50 is fixed to the drying component 40, the box component 1, and at least any one of the two or more small cylinders. It should be noted that the air inlet duct 50 can be fixed to more than two small cylinders at the same time, or only fixed to one of the small cylinders. By fixing the air inlet duct 50, the vibration that may occur when drying gas flows in the air inlet duct 50 can be suppressed. Moreover, by arranging the air inlet duct 50 between the two small cylinders, the air inlet duct 50 is rigidly connected to the two small cylinders, and the air inlet duct 50 can be used to fix the two small cylinders to form mutual counterweights to suppress the vibration generated when the small cylinders rotate. In addition, when the number of small cylinders is more than two, there can also be multiple air inlet ducts 50 accordingly. The multiple air inlet ducts 50 can be respectively located between two adjacent small cylinders in the multiple small cylinders, thereby also achieving the effect of suppressing the vibration generated when the multiple small cylinders rotate. The rigid connection method is not limited. For example, an additional connection part can be provided at a non-air inlet connection position on the outside of the outer shell of the air inlet duct 50. Preferably, at least one of the first air inlet 51 and the second air inlet 54 (including the air inlet connected to the small cylinder) is connected to the clothing processing chamber of at least one of the first large cylinder 10, two or more small cylinders (including but not limited to the first small cylinder 20, the second small cylinder 30) and the second large cylinder 90 by elastic connection of the elastic buffer or rigid connection, and the air inlet connection part 55 is connected to the drying assembly 40 by elastic connection of the elastic buffer or rigid connection. The air inlet (the first air inlet 51, the second air inlet 54, the air inlet connected to the small cylinder) is connected to the clothing processing chamber, and the air inlet connection part 55 is connected to the drying assembly 40 by elastic connection of the elastic buffer or rigid connection. The elastic buffer can be used to absorb the vibration that may be generated at the connection part, further improving the effect of absorbing vibration, or in the case where the large cylinder is a dryer cylinder, or the air inlet is not fixed to the clothing processing cylinder that vibrates, the connection structure can also be simplified by rigid connection. Similarly, for the air outlet duct 60, the air outlet parts (the first air outlet part 62, the second air outlet part 63, and other air outlet parts not shown in the figure) can be connected to the clothing processing chamber of at least one of the first large drum 10, two or more small drums (including but not limited to the first small drum 20 and the second small drum 30) and the second large drum 90 through the elastic connection of the elastic buffer or the rigid connection, and the air outlet connecting part 61 can be connected to the drying component 40 through the elastic connection of the elastic buffer or the rigid connection.
