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, there are only upper and lower double-zone washing / drying machines or single small-drum clothing processing equipment or devices consisting of 1 large-drum clothing processing equipment and 1 small-drum clothing processing equipment on the market. If underwear / underwear / socks or baby clothes need to be processed separately, more partitions are expected.

[0003] For an upper and lower dual-zone clothing processing device consisting of two large-drum clothing processing devices, when there is a need to use an additional small-drum clothing processing device, if the existing suspension support is used to set the small-drum clothing processing device between the two large-drum clothing processing devices as in the previous device consisting of one large-drum clothing processing device and one small-drum clothing processing device, although the vibration of the small drum can be suppressed, it will inevitably lead to the height of the entire device in the upper and lower directions being too large. Therefore, for the case of adding one or more small-drum clothing processing devices to an upper and lower dual-zone clothing processing device consisting of two large-drum clothing processing devices, a connection structure is needed that can suppress the vibration caused by the rotation of the small-drum clothing processing device to a certain extent and can also take into account miniaturization.

DETAILED DESCRIPTION

[0075] The following is an explanation of the implementation of the present application based on the accompanying drawings. It should be noted that the following description and the illustrations in the accompanying drawings are only examples of the present application and are not intended to limit the present application unless otherwise specified. Figure 1In the multi-drum clothing processing device 100 which is normally placed as shown, the side where the openings of the clothing processing drums (the first large drum 10, the first small drum 20, the second small drum 30, and the second large drum 40) are located is called the front side, the side opposite to the openings of the clothing processing drums is called the rear side, the side where the first large drum 10 is located is called the upper side, the side where the second large drum 40 is located is called the lower side, the side where the first small drum 20 is located is called the left side, and the side where the second small drum 30 is located is called the right side.

[0076] <Overall structure of multi-drum laundry processing device>

[0077] like Figure 1 As shown, as a typical example, the multi-drum laundry processing device 100 of the present application may be a laundry processing device including four laundry processing drums (a first large drum 10, a first small drum 20, a second small drum 30, and a second large drum 40).

[0078] 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 includes: a box assembly 1, which uses a frame to form a skeleton structure of the multi-drum laundry processing device 100, and by installing a metal plate or a plate-like body of other materials not shown in the figure on the frame, thereby forming the outer contour of the multi-drum laundry processing device 100, and forming a cavity space inside it; a first large drum 10, which is arranged on the upper side (i.e., the upper side) of the box assembly 1 in the cavity space; and a first small drum 20 and a second small drum 30, whose outer diameters are smaller than the first large drum 10, and the first large drum 10 in the cavity space is arranged at the upper side of the box assembly 1; The first small cylinder 20 and the second small cylinder 30 are arranged on the box assembly 1 through the connection device 50 described later. In addition, the first small cylinder 20 and the second small cylinder 30 can also be arranged on the top of the first large cylinder 10. There can also be a second large cylinder 40, which is arranged on the box assembly 1 below (that is, at the lower side) in the cavity space. That is, the second large cylinder 40 is arranged on the opposite side of the first large cylinder 10 relative to the first small cylinder 20 and the second small cylinder 30, 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 40 in the cavity space, and the outer diameter of the first small cylinder 20 and the second small cylinder 30 is also smaller than that of the second large cylinder 40. Figure 1 As shown, in the vertical direction, the first small drum 20 and the second small drum 30 are located below the first large drum 10 and above the second large drum 40, and are approximately in the middle of the multi-drum laundry processing device 100 in the vertical direction.

[0079] <Support Structure of Clothes Processing Drum>

[0080] As a clothing processing drum, the present application, for example, includes at least one small drum (at least one of the first small drum 20 and the second small drum 30) on the basis of including the first large drum 10 and the second large drum 40. Therefore, the present application can use 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 (such as 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 (such as adults, children, the elderly, patients, special occupations, and other factors). However, on the other hand, since the existing multi-drum clothing processing device does not give a clear disclosure of the connection device when adding a small drum to the clothing processing device having large drums at the top and bottom, if a large drum is added based on the existing device with only one large drum and one small drum, it is inevitable to avoid large-scale.

[0081] The inventors of the present application have conducted intensive research and found that, for a clothing processing device having upper and lower partitions of two large drums, by arranging at least one small drum between the two large drums using an elastic damping body in a compressive stress manner, it is possible to effectively suppress the vibration of the small drum during rotation without additionally providing other elastic suspension devices (such as tensile stress components such as springs). Compared with previous structures, this device can suppress vibration while achieving miniaturization.

[0082] In addition, for an existing device having only one large cylinder and one small cylinder, if another large cylinder is directly added, the input port of the upper large cylinder will become very high, and it is not easy for the user to perform operations such as putting in clothes. Here, by not using ordinary hanging springs or other methods to hang the small cylinder on the box body, space can be saved to a greater extent. As a result, especially for the structure of the present application having large cylinders on the upper and lower sides and a small cylinder in the middle, the space occupied by the fixing of the small cylinder can be significantly reduced, and space convenience is obtained.

[0083] In addition, the first large cylinder 10 and the second large cylinder 40 can be supported by the box assembly 1 using an existing suspension device.

[0084] <First Embodiment>

Figure 2The structure in which the support member 60 is located below the first small cylinder 20 and the second small cylinder 30 is shown, but it is not limited to this. Under the premise of not interfering with other components, the support member 60 can also be located above the first small cylinder 20 and the second small cylinder 30, or between the first small cylinder 20 and the second small cylinder 30, or between either the first small cylinder 20 or the second small cylinder 30 and the box assembly 1.

[0086] like Figure 5 As shown, the support member 60 has a protrusion 61 for installing the connecting device 50, the protrusion 61 has an opening 63, and a rising portion 62 is provided around the opening 63. The protrusion 61 protrudes in a direction relative to the support member 60 and the rising portion 62 stands in a direction opposite to the protrusion 61.

[0087] exist Figure 3 A top view of the structure supporting the first small cylinder 20 and the second small cylinder 30 is shown in FIG. Figure 4 It is shown in Figure 3 The sectional view from the AA direction in the figure. Figure 4 As shown, the first small tube 20 and the second small tube 30 are connected to the support member 60 through the connecting device 50. Figure 5 In the figure, the enlarged Figure 4 The area enclosed by the dotted frame.

[0088] Reference Figure 5 to Figure 7 , the connection device 50 according to the first embodiment will be described.

[0089] like Figure 6 , Figure 7 As shown, the connecting device 50 comprises: a gasket 51 having a through hole in the center thereof; a first elastic body 52 which is roughly cylindrical, one end of the cylindrical shape in the longitudinal direction (the end close to the gasket 51) is roughly flat, and the other end has a first base 521 on the radial outside, and a first protrusion 522 protruding from the first base 521 on the radial inside, and the first elastic body 52 has a first through hole 523 penetrating the entire first elastic body 52 at its center; a second elastic body 53 having a second base 531 and a second protrusion 532 on the end face on the side close to the first elastic body 51, the second protrusion 532 is located radially outward relative to the second base 531, and protrudes toward the side where the first elastic body 51 is located relative to the second base 531, and the second elastic body 53 has a second through hole 533 penetrating the entire second elastic body 53 at its center; and a gasket 54 having a through hole in the center thereof. The through holes of the washer 51, the first elastic body 52, the second elastic body 53, and the washer 54 are coaxial with each other. In addition, the connection device 50 also has a fastener such as a screw (not shown).

[0090] Reference Figure 8 to Figure 10, the first small cylinder 20 (second small cylinder 30) of the first embodiment is described.

[0091] like Figure 8 As shown, the first small cylinder 20 (the outer cylinder) is divided into a front cylinder 21 and a rear cylinder 22 in the front-to-back direction, and the second small cylinder 30 (the outer cylinder) is divided into a front cylinder 31 and a rear cylinder 32 in the front-to-back direction. The first small cylinder 20 and the second small cylinder 30 have the same structure, so only the first small cylinder 20 is described below, and the description of the second small cylinder 30 is omitted.

[0092] like Fig. 9 As shown, the front cylinder 21 has insertion parts 211 and 212 protruding downward, and screw holes 213 and 214 are provided at the top ends of the insertion parts 211 and 212. Fig.10 As shown, the rear tube 22 has insertion parts 221 and 222 protruding downward, and screw holes 223 and 224 are formed at the top ends of the insertion parts 221 and 222 .

[0093] Back again Figure 5 , the arrangement of the first small cylinder 20 and the connecting device 50 is described. The connection structures at the insertion parts 211, 212, 221, and 222 are the same, so the following description will only take the connection structure at the insertion part 212 as an example.

[0094] like Figure 5 As shown, the insertion portion 212 of the first small tube 20 is first inserted into the gasket 51, and then the insertion portion 212 of the first small tube 20 is further inserted into the first elastic body 52 in a manner that the end of the first elastic body 52 where the first protrusion 522 is not formed (the roughly flat end) abuts against the gasket 51, until the insertion portion 212 of the first small tube 20 passes through the first through hole 523 of the first elastic body 52 and further protrudes from the first through hole 523 relative to the first protrusion 522.

[0095] like Figure 5 As shown, the insertion portion 212 of the first small tube 20 together with the first protrusion 522 of the first elastic body 52 is inserted from one side of the support member 60 ( Figure 5 The upper side of the protrusion 522 is inserted into the opening 63 of the protrusion 61, and the protrusion degree of the first protrusion 522 relative to the first base 521 is equivalent to the sum of the wall thickness of the protrusion 61 and the standing degree of the rising portion 62 relative to the protrusion 61.

[0096] Likewise Figure 5 As shown, from the other side of the support member 60 ( Figure 5The second elastic body 53 and the gasket 54 are installed in sequence (on the lower side of the first cylinder 20), the insertion portion 212 of the first small cylinder 20 enters the second through hole 533 of the second elastic body 53, the first protrusion 522 and the rising portion 62 are opposite to the second base 531 of the second elastic body 53 in the vertical direction, and the second protrusion 532 of the second elastic body 53 and the first base 521 of the first elastic body 52 are in contact with the protrusion 61 in the vertical direction with the protrusion 61 sandwiched therebetween. Figure 5 In the left-right direction of the second elastic body 53, the second protrusion 532 of the second elastic body 53 is opposite to the first protrusion 522 of the first elastic body 52 via the rising portion 62. The second base 531 is opposite to the rising portion 62 in the rising direction (up-down direction) of the rising portion 62, and the second protrusion 532 is opposite to the rising portion 62 on the outer peripheral side of the rising portion 62. Although not shown in the figure, the second protrusion 532 may be opposite to the rising portion 62 on the inner peripheral side of the rising portion 62.

[0097] exist Figure 5 Although a screw (an example of a fastener) is not shown in the figure, during actual installation, the screw not shown is inserted into the through hole of the gasket 54 and further inserted into the screw hole 214 of the insertion portion 212 and threadedly fastened. The screw passes through the support member 60, the second elastic body 53 and the first elastic body 52, and is fastened to the first small cylinder 20. With the above structure, the first small cylinder 20 is installed on the support member 60 via the connecting device 50, and after the fastener is passed through the support member 60 and the elastic damping body (the first elastic body 52, the second elastic body 53), it is fastened to the small cylinder (the first small cylinder 20, the second small cylinder 30), so that the small cylinder can be firmly elastically supported on the elastic damping body and the support member of the connecting device with the help of the fastener. In addition, in Figure 2 , the structure in which four locations below the first small cylinder 20 (second small cylinder 30) are mounted on the support member 60 via the connecting device 50 is shown. However, the location and number of the connecting device 50 are not limited to Figure 2 As shown, as long as the first small tube 20 (second small tube 30) can be stably supported, the position (i.e., the position of the insertion portion on the small tube) and the number of the connecting devices 50 can be arbitrarily changed.

[0098] Furthermore, the support member 60 may not be provided, and the first small tube 20 and the second small tube 30 may be directly supported on the box assembly 1 by the connection device 50 .

[0099] In this embodiment, by having a multi-drum laundry processing device having a first large drum, a second large drum and at least one small drum, the capacity of processing laundry can be significantly increased compared to a device having only one large drum and one small drum. By installing the first small drum 20 and the second small drum 30 on the support 60 or the box assembly 1 via the connecting device 50, when the first small drum 20 and the second small drum 30 rotate, the first elastic body 52 of the connecting device 50 is compressed under the action of compressive stress, thereby absorbing the vibration generated when the first small drum 20 and the second small drum 30 rotate, achieving the effect of suppressing vibration. In addition, it has become a technical custom to use suspension springs to suppress the vibration of the drum in the prior art. However, the inventors of the present application have discovered that, for a multi-drum clothing processing device with upper and lower partitions such as the present application, instead of using springs or other components that suppress vibration based on the principle of tensile stress between the first large drum 10 and the second large drum 40, the first elastic body 52 (i.e., elastic damping body) that elastically supports the first small drum 20 and the second small drum 30 by compression is used. This can still achieve vibration suppression, and can also achieve miniaturization in the upper and lower directions by not using suspension springs.

[0100] Hereinafter, other embodiments of the present application will be described, and description of the same components as those of the first embodiment will be omitted.

[0101] <Second Embodiment>

[0102] The following is based on Figures 11 to 16 , the second embodiment is described.

[0103] exist Fig.11 In the figure, it is shown that Figure 4 The corresponding part of the cross-sectional view. Fig.12 , a perspective view of the support member 60a is shown, as shown in FIG. Fig.12 As shown in FIG. 1 , a through hole 62a is formed on the convex portion 61a, and as shown in FIG. Fig.13 As shown, an opening 63a is further formed on the protrusion 61a.

[0104] Reference Fig.13 , Fig.14 , a connection device 50a according to the second embodiment will be described.

[0105] exist Fig.13 In the Fig.11 The connecting device 50a of the second embodiment includes an elastic body 51a, and a through hole 53a penetrating the elastic body 51a is provided at the center of the elastic body 51a. Metal parts are connected to both ends of the elastic body 51a as the middle part, and a through hole connected to the through hole 53a of the elastic body 51a is formed at a portion of the metal part corresponding to the through hole 53a of the elastic body 51a.

[0106] exist Fig.14 , a perspective view of the elastic body 51a is shown. The elastic body 51a has, for example, two flanges on the outer periphery of the metal portion at one end thereof, and one through hole 54a is formed in each of the two flanges.

[0107] Reference Fig.15 , Fig.16 , the first small tube 20a (second small tube 30a) of the second embodiment is described.

[0108] As in the first embodiment, the first small tube 20a (the outer tube) is divided into a front tube 21a and a rear tube 22a in the front-to-back direction, and the second small tube 30a (the outer tube) is divided into a front tube and a rear tube in the front-to-back direction. The first small tube 20a and the second small tube 30a have the same structure, and therefore, only the first small tube 20a will be described below, and the description of the second small tube 30a will be omitted.

[0109] like Fig.15 As shown, the front cylinder 21a has protrusions 211a and 212a protruding downward, and screw holes 213a and 214a are provided at the top ends of the protrusions 211a and 212a. Fig.16 As shown, the rear cylinder 22a has protruding parts 221a, 222a protruding downward, and screw holes 223a, 224a are formed at the top ends of the protruding parts 221a, 222a.

[0110] Back again Fig.13 , the arrangement of the first small cylinder 20a and the connecting device 50a is described. The connection structures at the protrusions 211a, 212a, 221a, and 222a are the same, so the following description will only take the connection structure at the protrusion 212a as an example.

[0111] like Fig.13 As shown, the elastic body 51a is interposed between the protruding portion 212a of the first small cylinder 20a and the protruding portion 61a of the support member 60a in a manner that the through hole 53a of the elastic body 51a is coaxial with the screw hole 214a and the opening 63a of the protruding portion 212a. In addition, the two through holes 54a of the elastic body 51a are respectively opposite to the two through holes 62a of the protruding portion 61a, thereby enabling the elastic body 51a to be firmly fixed to the protruding portion 61a by screws.

[0112] exist Fig.13The screw (an example of a fastener) is not shown in the figure, but in actual installation, the screw not shown is inserted into the opening 63a of the protrusion 61a and further inserted into the screw hole 214a of the protrusion 212a through the through hole 53a of the elastic body 51a, and threadedly fastened. Through the above structure, the first small cylinder 20a is installed on the support member 60a via the connecting device 50a. In addition, similar to the first embodiment, there is no special restriction on the location and number of the connecting device 50a, as long as it can stably support the first small cylinder 20a (the second small cylinder 30a).

[0113] <Third Embodiment>

[0114] exist Fig.17 , a three-dimensional view of the structure of the supporting small cylinder of the third embodiment is shown.

[0115] In the multi-drum laundry processing device of the third embodiment, in addition to the connecting device 50b, there is also a second connecting device 55, which includes an elastic body. When the small drum rotates, the second connecting device 55 can elastically support the support member 60b by being compressed to help suppress the vibration of the small drum. In addition, the connecting device 50b is also a structure that suppresses the vibration of the small drum based on compressive stress, that is, it includes an elastic damping body that can be deformed in a compressed manner when the small drum rotates.

[0116] exist Fig.17 In the figure, an enlarged diagram is shown for the structure of connecting the support member 60b and the box assembly 1b via the second connecting device 55. The support member 60b in the third embodiment is connected to the box assembly 1b at one end in its length direction (left-right direction). The second connecting device 55 is between the support member 60b and the box assembly 1b. According to the third embodiment, in addition to using the connecting device 50b to suppress vibration when the small cylinder rotates, the second connecting device 55 can also be used to suppress the vibration transmitted to the support member 60b from being transmitted to the box assembly 1b. Thereby, the vibration can be further suppressed, and the structure of the second connecting device 55 can be miniaturized.

[0117] <Fourth Implementation Method>

[0118] exist Fig.18 , a three-dimensional view of the structure of the supporting small cylinder of the fourth embodiment is shown.

[0119] In the multi-drum laundry processing device of the fourth embodiment, there is a support member 60c that matches the shape of the first small drum 20, so that the support member 60c surrounds the first small drum 20 and is arranged on the outer periphery of the first small drum 20, and there is a gap between the support member 60c and the first small drum 20. In the roughly annular space between the support member 60c and the first small drum 20, a plurality of elastic bodies of the connecting device 50c are arranged and installed along the outer periphery of the first small drum 20. In addition, the intervals between the plurality of elastic bodies are not particularly limited, as long as they can absorb vibration by compression in the up, down, left, and right directions as the small drum rotates.

[0120] An opening is formed at a portion of the support member 60c corresponding to the connecting device 50c, through which the connecting device 50c passes. The connecting device 50c can be an integrally formed elastic body, or a separately formed elastic body, which is assembled from the inner and outer sides of the support member 60c. The small tube can be directly connected to the box assembly 1 via the connecting device 50c, or can be connected to the box assembly 1 via the support member 60c.

[0121] When the first small cylinder 20 rotates, the first small cylinder 20 vibrates in the up-down direction or the left-right direction. Since the connecting device 50c in the roughly annular space between the support member 60c and the first small cylinder 20 is evenly distributed in the up-down direction and the left-right direction of the first small cylinder 20, when the first small cylinder 20 vibrates in the up-down direction or the left-right direction, the connecting device 50c is correspondingly compressed to suppress the vibration.

[0122] Therefore, the structure of the fourth embodiment can also suppress vibration well and achieve miniaturization.

[0123] <Fifth Implementation Method>

[0124] exist Fig.19 , Fig. 20 , a three-dimensional view of the structure of the supporting small cylinder of the fifth embodiment is shown.

[0125] In the multi-drum laundry processing device of the fifth embodiment, there is a support member 60d matching the shape of the first small drum 20, so that the support member 60d is arranged on the outer periphery of the first small drum 20 to surround the first small drum 20, and there is a gap between the support member 60d and the first small drum 20. In the substantially annular space between the support member 60d and the first small drum 20, connecting devices 50d1 and 50d2 are arranged in a manner extending along the circumferential direction of the outer periphery of the first small drum 20.

[0126] exist Fig. 20 The structure after the support member 60d is removed is shown in FIG. Fig. 20As shown, the connecting device 50d1 surrounds the first small tube 20 on the entire circumference, and the connecting device 50d2 is arranged on the outer circumference of the first small tube 20 behind the connecting device 50d1 so as to surround most of the first small tube 20 (for example, more than 80% of the entire circumference).

[0127] Specifically, the outer periphery of the front tube of the first small tube 20 is circular (refer to Fig. 9 , Fig.15 ), the connecting device 50d1 is in a circular shape and is placed on the front tube of the first small tube 20 in a manner that surrounds the front tube of the first small tube 20, and the outer periphery of the rear tube of the first small tube 20 is in a shape with a protruding portion below the circle (refer to Fig.10 , Fig.16 ), the connecting device 50d2 is formed on the outer periphery of the rear tube of the first small tube 20 in a manner avoiding the protruding portion, thereby forming a circular ring shape with a gap, that is, a continuous substantially C-shape. Of course, the connecting devices 50d1 and 50d2 are not limited thereto, and the connecting devices 50d1 and 50d2 may both be circular rings, or the connecting devices 50d1 and 50d2 may both be substantially C-shaped. In short, the connecting device of the fifth embodiment is an embodiment in which a continuous elastic body is formed into a circular ring shape or a substantially C-shape.

[0128] The thickness of the connecting devices 50d1 and 50d2 is substantially equal to or slightly greater than the distance between the supporting member 60d and the first small tube 20. The front-to-back length of the connecting device 50d2 is greater than the front-to-back length of the connecting device 50d1.

[0129] Therefore, when the first small cylinder 20 rotates, the connecting device 50d1 as an elastic body that surrounds the first small cylinder 20 all around and the connecting device 50d2 as an elastic body that surrounds most of the first small cylinder 20 can be reliably compressed as the first small cylinder 20 rotates, thereby suppressing vibration during rotation and achieving miniaturization.

[0130] <Sixth Implementation Method>

[0131] exist Fig.21 , Fig. 22 , a stereoscopic view of the structure of the supporting small cylinder of the 6th embodiment is shown.

[0132] In the multi-drum laundry processing device of the sixth embodiment, there is a support member 60e that matches the shape of the first small drum 20, so that the support member 60e is arranged on the outer periphery of the first small drum 20 to surround the first small drum 20, and there is a gap between the support member 60e and the first small drum 20. In the substantially annular space between the support member 60e and the first small drum 20, connecting devices 50e1 and 50e2 are provided.

[0133] exist Fig. 22The structure after the support member 60e is removed is shown in FIG. Fig. 22 As shown, the connection device 50e1 is based on the connection device 50d1 of the fifth embodiment, and the elastic body of the connection device 50e1 is set to an arc shape, and a plurality of arc-shaped elastic bodies are intermittently arranged on the outer periphery of the front tube in the circumferential direction of the front tube. The connection device 50e2 is based on the connection device 50d2 of the fifth embodiment, and the elastic body of the connection device 50e2 is set to an arc shape, and a plurality of arc-shaped elastic bodies are intermittently arranged on the outer periphery of the front tube in the circumferential direction of the rear tube. The front-to-back length of the connection device 50e2 is greater than the front-to-back length of the connection device 50e1.

[0134] The multiple elastomers of the connecting device 50e1 and the multiple elastomers of the connecting device 50e2 are roughly evenly arranged between the small cylinder and the support member along the outer circumference of the small cylinder. Here, "roughly evenly" means that there is no need to make the intervals between the multiple elastomers the same. It is only necessary to arrange the elastomers at regular intervals along the outer circumference of the first small cylinder 20 so that they can absorb vibrations by compression in the up, down, left and right directions as the small cylinder rotates.

[0135] Likewise, when the first small cylinder 20 rotates, the connecting devices 50e1 and 50e2 intermittently arranged along the circumferential direction of the first small cylinder 20 can be compressed as the first small cylinder 20 rotates, thereby suppressing vibration during rotation and achieving miniaturization.

[0136] In the above-mentioned 4th to 6th embodiments, the elastic support of the small cylinder by the elastic damping body can be realized through various forms. In these forms, the elastic damping body is arranged along the outer circumference of the small cylinder or formed continuously, thereby making it possible to elastically support the small cylinder more reliably and absorb the vibration caused by the rotation of the small cylinder.

[0137] <Seventh Implementation Method>

[0138] exist Fig.23 , a stereoscopic view of the structure of the supporting small cylinder of the 7th embodiment is shown.

[0139] In the multi-drum laundry processing device of the seventh embodiment, an elastic vibration-damping sheet 56 is provided between the small drum and the box assembly 1 to connect the small drum and the box assembly 1. Fig.23 As shown, an elastic damping sheet 56 is connected to the outer side of the first small cylinder 20 (the outer cylinder) (i.e., the side of the first small cylinder 20 opposite to the second small cylinder 30). The elastic damping sheet 56 is plate-shaped and extends in the vertical direction. The upper and lower ends of the elastic damping sheet 56 are connected to the box assembly 1 via elastic bodies 57 (elastic damping bodies). The same arrangement is performed for the second small cylinder 30 (refer to Fig.23), the description of setting the elastic vibration damping plate 56 for the second small cylinder 30 is omitted here, and the technical effects described below for the first small cylinder 20 can also be applied to the second small cylinder 30.

[0140] With this structure, the elastic vibration-damping sheet 56 can absorb the left-right vibration generated when the first small cylinder 20 rotates. Preferably, the portion of the first small cylinder 20 closest to the box assembly 1 (i.e., Fig.23 The leftmost part of the first small cylinder 20 in the figure is connected to the elastic vibration damping plate 56, and the part where the first small cylinder 20 is connected to the elastic vibration damping plate 56 is located in the middle position of the elastic vibration damping plate 56 in the up-down direction. Thus, the elastic vibration damping plate 56 can be used to uniformly absorb the vibration from the first small cylinder 20, and prevent the upper and lower parts of the elastic vibration damping plate 56 from bending to different degrees, resulting in failure to absorb the vibration well. Alternatively, for one elastic vibration damping plate 56, the first small cylinder 20 can have multiple parts connected to the one elastic vibration damping plate 56, and the multiple connection parts are symmetrical to each other with respect to the middle position of the elastic vibration damping plate 56 in the up-down direction. Thus, the vibration from the first small cylinder 20 can also be uniformly transmitted to the elastic vibration damping plate 56.

[0141] A plurality of elastic vibration-damping sheets 56 may be provided for the first small cylinder 20, and the plurality of elastic vibration-damping sheets 56 are arranged along the front-to-back direction (depth direction) of the first small cylinder 20 on the outside of the first small cylinder 20 (between the first small cylinder 20 and the box assembly 1). Thus, the vibration of the first small cylinder 20 can be more reliably absorbed, further improving the effect of absorbing vibration.

[0142] As for the connection between the elastic vibration damping sheet 56 and the box assembly 1, it is preferred to connect the elastic body 57 (elastic damping body) to the box assembly 1, thereby, not only the elastic vibration damping sheet 56 but also the elastic body 57 can absorb vibration, which can further improve the effect of absorbing vibration. However, the elastic body 57 may not be provided, that is, the elastic vibration damping sheet 56 is rigidly connected to the box assembly 1. In addition, the elastic vibration damping sheet 56 may not extend in the up-down direction, but in the front-back direction, that is, the same as the depth direction of the first small tube 20.

[0143] like Fig.23 As shown, a connecting plate 58 may also be provided between the first small cylinder 20 and the second small cylinder 30, thereby connecting the first small cylinder 20 and the second small cylinder 30 as a whole, so as to better reduce vibration of the first small cylinder 20 and the second small cylinder 30. For example, for the vibration of the first small cylinder 20 in the left and right directions, not only the elastic vibration-damping plate 56 on the side of the first small cylinder 20 but also the elastic vibration-damping plate 56 on the side of the second small cylinder 30 can be used for vibration reduction.

[0144] In this embodiment, an elastic damping sheet 56 connecting the small tube to the box assembly 1 is provided on the side (the left side of the first small tube 20, the right side of the second small tube 30) closest to the box assembly 1 in one or more small tubes (for example, the first small tube 20, the second small tube 30, or more small tubes). That is, in the case of only one small tube, the elastic damping sheet 56 can be provided on at least one of the left and right sides of the small tube, preferably both sides. In the case of multiple small tubes, the elastic damping sheet 56 can be provided between the small tube close to the box assembly 1 among the multiple small tubes and the box assembly.

[0145] The various embodiments described above can be used in combination as long as they do not conflict with each other. For example, the third embodiment and the seventh embodiment can be used together with other embodiments, and the different forms of connecting devices in the first embodiment, the second embodiment, and the fourth to sixth embodiments can be mixed and used without conflict. In addition, in the fourth to sixth embodiments, it is preferred that the support member surrounds the small tube so that the support member can be used to support the small tube more reliably, but the support member may not surround the small tube.

[0146] <Others>

[0147] The elastic bodies in the above embodiments are elastic dampers, preferably rubber dampers, air dampers, hydraulic dampers, and metal dampers. By selecting commercially available elastic bodies, the versatility of the parts used in the device can be improved.

[0148] The fasteners of the connecting device may not be inserted through the support and the elastic damping body, or a plurality of fasteners may be installed at both ends of the elastic damping body, and the plurality of fasteners extend from the elastic damping body to a direction away from the elastic damping body. Thus, by inserting and fastening at least one fastener from the elastic damping body toward the small cylinder, and inserting and fastening at least one fastener from the elastic damping body toward the support (or box assembly), the small cylinder can also be elastically supported on the support or box assembly. When the small cylinder vibrates due to rotation, the vibration is absorbed by compressing the elastic damping body. Thus, the small cylinder can also be elastically supported firmly on the elastic damping body of the connecting device with the help of fasteners, and the elastic damping body of the connecting device can be firmly supported on the support with the help of fasteners. Here, the situation in which multiple fasteners are installed at both ends of the elastic damping body not only includes a structure in which the fasteners are installed at both ends with an elastomer (such as a rubber elastomer) in the middle, and the multiple fasteners are respectively fixed to the support (or box assembly) and the small tube using nuts, but also includes a structure in which, for a metal shock absorber, the upper part of the metal shock absorber is fixed to the small tube using fasteners, and the lower part of the metal shock absorber is fixed to the support (or box assembly) using another fastener.

[0149] The large and small barrels as the laundry treatment barrels usually have an inner barrel and an outer barrel, the inner barrel is rotatable, and the outer barrel is fixed and non-rotatable. The front barrel and the rear barrel recorded in the above description refer to the front barrel and the rear barrel of the outer barrel. In the above embodiment, the first small barrel 20 and the second small barrel 30 are respectively connected to a support 60 via a plurality of connecting devices 50, and are connected to the box assembly 1 by means of the one support 60. However, it is not limited to this, and it can also be that the first small barrel 20 and the second small barrel 30 are respectively connected to a plurality of supports 60 via a plurality of connecting devices 50, and are connected to the box assembly 1 by means of the plurality of supports 60. It can also be that the first small barrel 20 and the second small barrel 30 are respectively connected to different supports 60 via a plurality of connecting devices 50, that is, the first small barrel 20 is connected to the box assembly 1 by means of one or more supports 60, and the second small barrel 30 is connected to the box assembly 1 by means of other one or more supports 60. By connecting a plurality of small barrels to the box assembly respectively through a plurality of connecting devices, the plurality of small barrels can be reliably elastically supported respectively. If a supporting member is provided on the basis of the connecting device, the connecting device can be more easily supported, and even the part of the outer periphery of the small barrel that is difficult to connect to the box assembly can be connected to the box assembly with the support member. In short, as long as the first small barrel 20 and the second small barrel 30 can be well supported, it is possible for both small barrels to be directly connected to the box assembly 1, or to be flexibly connected to the box assembly 1 with the same supporting member, different supporting members, or partially the same supporting members, or to be directly connected to the box assembly 1 and to the supporting member 60.

[0150] Alternatively, the first small cylinder 20 and the second small cylinder 30 have inner cylinders that rotate respectively, and a common outer cylinder that surrounds their inner cylinders, and the outer cylinder can be oval-shaped. In this case, the oval-shaped outer cylinder is connected to the box assembly 1 and / or the support 60 using a connecting device 50. Alternatively, the first small cylinder 20 and the second small cylinder 30 each have a separate outer cylinder, rather than a common outer cylinder. In this case, the outer cylinders of the first small cylinder 20 and the second small cylinder 30 are connected as one body using a connecting member, and then the outer cylinders (the first small cylinder 20 and the second small cylinder 30) connected as one body are connected to the box assembly 1 and / or the support 60 via a connecting device 50. By forming a plurality of small cylinders as one body or connecting them as one body, it is possible to uniformly support a plurality of small cylinders, and reliably elastically support a plurality of small cylinders.

[0151] The following is an explanation of the peripheral structure of the clothing processing drum (especially the first small drum 20 and the second small drum 30, but not limited to the two small drums). 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 (the side of the first small drum 20 and the second small drum 30). By effectively utilizing the peripheral space of the clothing processing drum, the multi-drum clothing processing device of the present application can be constructed more compactly, which complements the structure of elastically supporting the small drums using the connecting device, and the coordinated structure of the two can further achieve miniaturization.

[0152] exist Fig.24 , Fig.25 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. Fig.26 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 40 are completely removed.

[0153] like Fig.24 As shown, the air inlet duct 80 of the present application is constructed as follows: in the left-right direction, at least a portion of the air inlet duct 80 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. Fig.25 As shown, an air outlet connection portion 91 serving as a part of the air outlet duct 90 is provided on the rear side of the first small tube 20 .

[0154] exist Fig.26 In the figure, the first small cylinder 20 and the second small cylinder 30 are removed. Fig.26It can be seen that a drying module 70 is provided at the rear side of the first small cylinder 20 and the second small cylinder 30. The drying module 70 is provided between the first large cylinder 10 and the second large cylinder 40 in the up-down direction. The drying module 70 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 91 as a part of the air outlet duct 90 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 91 of the drying module 70 and the air outlet duct 90 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 module 70, at least a part of the air inlet duct 80, and at least a part of the air outlet duct 90 are provided at the same time, so as to realize the compact layout of the peripheral structure of the clothing processing cylinder.

[0155] The following is based on Figure 27 to Figure 31 , the structures of the drying module 70, the air inlet duct 80, and the air outlet duct 90 are described.

[0156] <Drying Module>

[0157] The drying module 70 is used to heat the air to generate drying air. Fig. 27 As shown, the drying module 70 has an upper shell and a lower shell, and the upper shell and the lower shell are engaged with each other, so that components such as a compressor, an evaporator, and a condenser (not shown) are accommodated inside the drying module 70. Of course, the compressor is not necessarily arranged inside the drying module 70, and a structure for installing the compressor can also be arranged on the lower shell without the upper shell engaging and covering.

[0158] An opening 71 is provided at the front portion of the drying module 70 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. Fig. 27 In the example shown, the opening 71 is opened in the upper shell, but it can also be opened in the lower shell, which is not limited to this. Fig. 27 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 module 70, where the air is heated to generate drying air. In this embodiment, the opening 71 is connected to the air inlet connection portion 85 of the air inlet duct 80 described later (see FIG. 1 ). Fig.30 ), thereby enabling air to be delivered to the drying module 70.

[0159] exist Fig.28 , a stereoscopic view of the drying module 70 viewed from the rear side (the side opposite to the first small cylinder 20 and the second small cylinder 30) is shown. Fig.28The driving unit is omitted in the figure. The upper part of the housing of the drying module 70 has a mounting portion, and the driving unit can be arranged at the mounting portion of the upper part of the housing of the drying module 70, 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 module 70 as the mounting portion for mounting the driving unit, there is no need to provide an additional mounting portion for mounting the driving unit, and miniaturization in the vertical direction can also be achieved. More preferably, the mounting portion is set as a groove, such as Fig.28 As shown, the upper portion of the upper housing facing upward has a groove, which is used to install the drive unit. Fig. 27 The structure in which the driving part is installed in the groove is shown in FIG. By providing a groove on the drying module 70 to install the driving part, it can be further miniaturized in the vertical direction.

[0160] In addition, Fig.28 7 shows that the lower housing has an opening 72, which is used to send out the dry gas generated in the drying module 70, that is, the air in the laundry processing drum is guided to the drying module 70 through the opening 71, the air is heated into dry gas in the drying module 70, and the dry gas is sent out from the drying module 70 through the opening 72. In this embodiment, the opening 72 is connected to the outlet connection portion 91 of the outlet duct 90 described later (refer to Fig.31 ).

[0161] And, if Fig.28 As shown, there is a recess 73 at the rear side of the drying module 70, which corresponds to the portion of the housing of the drying module 70 protruding forward, and is used to set the main part of the air outlet duct 90. The portion opposite to the opening 72 of the drying module 70 is used to set the air outlet connection portion 91 of the air outlet duct 90.

[0162] <Air inlet duct>

[0163] The air inlet duct 80 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 40) to the drying module 70. Fig.29 and Fig.30 FIG. 8 shows a three-dimensional view of the air inlet duct 80. Fig.32 As shown, the air inlet duct 80 is configured as follows: at least a portion of the air inlet duct 80 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-back direction. Thus, the installation space of the air duct can be saved and further miniaturization can be achieved. 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.29 This is a three-dimensional view of the air inlet duct 80 viewed from the front side (the opening side of the laundry treatment drum). Fig.29As shown, the air inlet duct 80 has a first air inlet portion 81 formed upward and opened upward at the upper part, and has a second air inlet portion 84 formed downward and opened rearward at the lower part. By forming the first air inlet portion 81 facing upward, the path from the first large drum 10 to the air inlet duct 80 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 84 facing downward, the path from the second large drum 40 to the air inlet duct 80 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 81 and the second air inlet portion 84 between the first air inlet portion 81 and the second air inlet portion 84, and the main body portion has a bending portion 86 and a bending portion 87 at a position between the first small cylinder 20 and the second small cylinder 30, and the bending portion 86 and the bending portion 87 are local bends along the outer peripheral surface of the cylinder body of the first small cylinder 20 and the second small cylinder 30.

[0164] The air inlet duct 80 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.

[0165] Regarding the space between the two small tubes, the air inlet duct 80 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.

[0166] Specifically, the air inlet duct 80 has a curved portion 86 on the side opposite to the first small tube 20 in the left-right direction, and has a curved portion 87 on the side opposite to the second small tube 30 in the left-right direction, that is, the air inlet duct 80 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 86 and 87, 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.

[0167] like Fig.29As shown, the curved portion 86 has a radius of curvature that is substantially the same as the radius of curvature of the cylindrical shape of the first small cylinder 20. The curved portion 86 extends downward in a curved manner from a position substantially directly above the first small cylinder 20 along the outer circumference of the cylindrical shape of the first small cylinder 20 to a position below the position of the central axis of the cylindrical shape of the first small cylinder 20. Thus, in the circumferential direction of the cylindrical shape of the first small cylinder 20, the curved portion 86 partially surrounds the outer circumference of the first small cylinder 20, for example, within an angular range of 90° to 150°.

[0168] like Fig.29 As shown, the curved portion 87 has a radius of curvature substantially the same as the radius of curvature of the cylindrical shape of the second small cylinder 30, and the curved portion 87 extends downwardly in a curved manner from a position substantially directly above the second small cylinder 30, along the outer circumference of the cylindrical shape of the second small cylinder 30, to a position below the position of the central axis of the cylindrical shape of the second small cylinder 30, and further extends around the second small cylinder 30 to a position substantially directly below the second small cylinder 30, and then extends horizontally to a position between the second small cylinder 30 and the box assembly 1. Thus, in the circumferential direction of the cylindrical shape of the second small cylinder 30, the curved portion 87 partially surrounds the outer circumference of the second small cylinder 30, for example, within an angle range of 180° to 210°.

[0169] There is no particular limitation on the extension length of the curved portions 86 and 87 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.29 In the embodiment, the main body portion where the bent portions 86 and 87 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.

[0170] exist Fig.30 FIG. 8 shows a three-dimensional view of the air inlet duct 80 from another viewing angle. Fig.30 This is a three-dimensional view of the air inlet duct 80 viewed from the rear side (the side where the drying module 70 is located). Fig.30 As shown in the figure, the air inlet duct 80 has an air inlet connection portion 85 protruding and extending toward the rear side, and the air inlet connection portion 85 is connected to the opening 71 of the drying module 70 facing the front. The direction in which the air inlet duct 80 guides air to the drying module 70 is shown by the arrow at the air inlet connection portion 85 in the figure, thereby, the air in the air inlet duct 80 can be guided into the drying module 70 via the air inlet connection portion 85. The air inlet directions of the first air inlet portion 81 and the second air inlet portion 84 are shown in FIG. Fig.30 As shown by the arrows at each air inlet portion.

[0171] In addition, if Fig.30As shown, similar to the structure of the curved portion 86 and the curved portion 87, the air inlet connection portion 85 of the air inlet duct 80 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 86 and the curved portion 87 of the air inlet duct 80 not interfere with the first small cylinder 20 and the second small cylinder 30, but the air inlet connection portion 85 of the air inlet duct 80 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.30 As shown, a triangular support member 88 is also provided on the lower side of the air inlet connection portion 85. The thickness (dimension in the left-right direction) of the support member 88 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 support member 88 based on such a structure can reliably support the overall structure of the air inlet duct 80, especially the air inlet connection portion 85, 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 85, and, because the thickness of the support member 88 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.

[0172] like Fig.29 , Fig.30 As shown, the first air inlet 81 is, for example, a portion that protrudes upward from the main body and opens upward. The first air inlet 81 is connected to the first large cylinder 10, thereby guiding the air inside the first large cylinder 10 into the air inlet duct 80. The air inlet duct 80 also has other air inlets that are connected to the first small cylinder 20 and the second small cylinder 30, and illustration and description are omitted here. The second air inlet 84 is, for example, a portion that is at the lower part of the main body and opens toward the rear from the main body, and the second air inlet 84 is connected to the second large cylinder 40, thereby guiding the air inside the second large cylinder 40 into the air inlet duct 80.

[0173] <Air outlet duct>

[0174] The air outlet duct 90 is used to deliver the dry air heated by the drying module 70 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 40). Fig.31 , a perspective view of the air outlet duct 90 viewed from the front side is shown. Fig.31As shown, the air outlet duct 90 has an air outlet connection portion 91 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 91 is connected to the drying module 70, and the air in the drying module 70 flows into the air outlet duct 90 via the air outlet connection portion 91. Since the air outlet connection portion 91 is configured in a manner that its main surface direction faces the left-to-right direction, even if the drying module 70 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 91 can be configured to be arranged in the left-to-right direction with the drying module 70. 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.

[0175] Likewise Fig.31 As shown, the air outlet duct 90 also has a main body with the vertical direction as the length direction (i.e., the vertical dimension 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 module 70 is set at the rear side of the first small cylinder 20 and the second small cylinder 30, the remaining space between the drying module 70 and the box assembly 1 is small. If the main body has a larger size in the front-to-back direction, the main body cannot be set at the recess 73 of the drying module 70. In addition, since the size of the first large cylinder 10 and the second large cylinder 40 is larger, the space between the two large cylinders and the box assembly 1 is also small. 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 40. The main body has a first air outlet 92 formed upward and opened to the front at the upper part of the upper side, and the main body has a second air outlet 93 formed downward and opened to the front at the lower part of the lower side. By forming the first air outlet portion 92 facing upward, the path from the air outlet duct 90 to the first large drum 10 can be shortened, so that the air in the drying module 70 can easily enter the clothing processing drum, reducing wind resistance. By forming the second air outlet portion 93 facing downward, the path from the air outlet duct 90 to the second large drum 40 can be shortened, so that the air in the drying module 70 can easily enter the clothing processing drum, reducing wind resistance.

[0176] Combination Fig.26 and Fig.31 , the configuration position of the air outlet duct 90 is described, such as Fig.26As shown, the air outlet connection portion 91 of the air outlet duct 90 is arranged with the drying module 70 in the left-right direction and communicated with the drying module 70. The main body of the air outlet duct 90 is formed at the rear side of the air outlet connection portion 91 and the drying module 70, the part of the main body formed with the first air outlet portion 92 extends upward to the rear side of the first large cylinder 10 and communicates with the first large cylinder 10, and the part of the main body formed with the second air outlet portion 93 extends downward to the rear side of the second large cylinder 40 and communicates with the second large cylinder 40. In addition, as shown in FIG. Fig.31 As shown, the air outlet duct 90 also has an opening 94 connected to the first small cylinder 20 and the second small cylinder 30. Through the opening 94, the air outlet duct 90 is connected to the first small cylinder 20 and the second small cylinder 30, thereby delivering the gas heated in the drying module 70 to the first small cylinder 20 and the second small cylinder 30.

[0177] As described above, by making the air outlet duct 90 have an air outlet connection portion 91 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 module 70 can be utilized. By making the air outlet duct 90 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 (the space in the recess 73) of the drying module 70, the rear space of the first large cylinder 10, and the rear space of the second large cylinder 40 can be utilized.

[0178] As described above, by connecting the air outlet connection part 91 to the drying module 70, connecting the first air outlet part 92 to the first large cylinder 10, and connecting the second air outlet part 93 to the second large cylinder 40, the drying gas generated in the drying module 70 can be circulated.

[0179] 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 80 via the first air inlet portion 81, and then guided to the drying module 70 via the air inlet connection portion 85 via the opening 71, and is heated in the drying module 70 to generate dry gas. Thereafter, the air passes through the opening 72 of the drying module 70 and the air outlet connection portion 91 of the air outlet duct 90 into the air outlet duct 90, and then the dry gas circulates inside the air outlet duct 90 to the first air outlet portion 92, and enters the first drum 10 via the first air outlet portion 92, thereby realizing the circulation of gas in the first drum 10, the air inlet duct 80, the drying module 70, the air outlet duct 90, and the first drum 10. The same is true for drying the clothes in the first small drum 20, the second small drum 30, and the second large drum 40. Through different air outlets, the gas is circulated between the drying module 70 and the first small drum 20 (or the second small drum 30, the second large drum 40).

[0180] <Effects of the small tube's peripheral structure>

[0181] exist Fig.32 , 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.32 As shown, the air inlet connecting portion 85 and the first air inlet portion 81 of the air inlet duct 80 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 80 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 40 located below can be subjected to the transmission of drying gas thereto.

[0182] As described above, since at least a portion of the air inlet duct 80 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 module 70 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 80, the distance between the drying module 70 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 module to provide drying gas for each clothing processing cylinder, and improves the utilization rate of space. When the drying module 70 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.

[0183] 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.32 As shown, a drying module 70 is provided at the rear side of the first small cylinder 20 and the second small cylinder 30, and the drying module 70 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 module 70 can be fully ensured, and it can be ensured that the drying module 70 can generate sufficient drying gas to meet the drying needs of multiple clothing processing cylinders.

[0184] In addition, if Fig.32As shown, even if a sufficiently large drying module 70 is provided, at least a portion of the air outlet duct 90 (for example, the air outlet connection portion 91) 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 90 is provided in the recessed portion at the rear side of the drying module 70. 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.

[0185] <Other structures and modifications of the present application>

[0186] (1) When the multi-drum laundry processing device is viewed from the front, an imaginary line connecting the centers of the circles formed by the first small drum 20 and the second small drum 30 is at an angle of 0 to 15 degrees relative to the horizontal plane. More preferably, the imaginary line is parallel to the horizontal plane.

[0187] (2) In the multi-drum clothing processing device of the present invention, the small drum 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, the two or more small drums may be arranged between the first large drum 10 and the second large drum 40 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 size of the device in the up-down direction. The two or more small drums may also be arranged in two layers between the first large drum 10 and the second large drum 40. In this case, miniaturization can be achieved while suppressing vibration by elastically supporting the small drums by compressing the elastic damping body. In addition, the air inlet duct 80 is arranged in the peripheral space of any small drum, and the space around the small drum is fully utilized to further achieve the miniaturization of the device as a whole. For example, at least a portion of the air inlet duct 80 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 and the small tube are compactly arranged without the need to prepare additional space for setting up the duct.

[0188] (3) The drying module 70 can be arranged on the rear side of the first small cylinder 20 and the second small cylinder 30, or it can 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 module 70 is arranged on the upper side or the lower side, the depth 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 80 can also be arranged by using the space around the first small cylinder 20 and the second small cylinder.

[0189] (4) For the air inlet duct 80 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.

[0190] (5) The air inlet duct 80 may 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 40, 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 40 into the drying module 70. The air outlet duct 90 may 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 40 corresponding to the air inlet duct 80, and guide the air heated by the drying module 70 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 40.

[0191] (6) The air outlet portion of the air outlet duct (the first air outlet portion 92, the second air outlet portion 93, 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 40 from the rear, and the air in the air outlet duct 90 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 40 via the air outlet portion. As a result, not only can the drying gas circulate between the clothing processing drum and the drying module 70 based on the air inlet duct 80 and the air outlet duct 90 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.

[0192] (7) There may be only one or both of the curved portions 86 and 87. In addition, the curved portions 86 and 87 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.

[0193] (8) The orientation (opening direction) of the openings of the first air inlet 81 and the second air inlet 84 described above is not particularly limited as long as the circulation of the gas is satisfied.

[0194] (9) A duct fan 95 for flowing air is provided in at least one of the air inlet duct 80 and the air outlet duct 90. By providing the duct fan 95 in at least one of the air inlet duct 80 and the air outlet duct 90, the circulation of the drying gas in the duct can be facilitated. Fig.32In the figure, the housing of the air outlet duct 90 is omitted, and the duct fan 95 disposed in the air outlet duct 90 is shown. For example, the air outlet connection portion 91 is provided with a duct fan 95 for making air flow, and the duct fan 95 is disposed on the side of the drying module 70 in the left-right direction, and its rotation axis extends in the left-right direction. By arranging the duct fan 95 on the side of the drying module 70, it can not only help the drying gas to circulate in the duct, but also effectively utilize the side space of the drying module 70, which is conducive to further miniaturization.

[0195] (10) The cooling fan 74 is provided on the rear side of the drying module 70 , and the cooling fan 74 may be provided on one of the left and right side surfaces of the drying module 70 .

[0196] (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 80 and the air outlet duct 90, 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.

[0197] (12) A fragrance is provided in at least one of the air inlet duct 80 and the air outlet duct 90 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.

[0198] (13) A filter assembly is provided in the air inlet duct 80. The air introduced into the air inlet duct 80 is filtered by the filter assembly and then guided to the drying module 70. The filter assembly can filter out clothing threads, fluff and other thread debris contained in the drying gas. In addition, the air inlet duct 80 is fixed to the drying module 70, the box assembly 1, and at least any one of the two or more small cylinders. It should be noted that the air inlet duct 80 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 80, the vibration that may occur when drying gas flows in the air inlet duct 80 can be suppressed, and by arranging the air inlet duct 80 between the two small cylinders, the air inlet duct 80 is rigidly connected to the two small cylinders, and the air inlet duct 80 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 80 accordingly. The multiple air inlet ducts 80 can be respectively located between two adjacent small cylinders among the multiple small cylinders, thereby also achieving the effect of suppressing the vibration generated when the multiple small cylinders rotate. The method of rigid connection 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 80. Preferably, at least one of the first air inlet 81 and the second air inlet 84 (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 40 by elastic connection of the elastic buffer or rigid connection, and the air inlet connection part 85 is connected to the drying module 70 by elastic connection of the elastic buffer or rigid connection. The air inlet (the first air inlet 81, the second air inlet 84, the air inlet connected to the small cylinder) is connected to the clothing processing chamber, and the air inlet connection part 85 is connected to the drying module 70 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 vibrating clothing processing cylinder, the connection structure can also be simplified by rigid connection. Similarly, for the air outlet duct 90, the air outlet parts (the first air outlet part 92, the second air outlet part 93, 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 40 through the elastic connection of the elastic buffer or the rigid connection, and the air outlet connecting part 91 can be connected to the drying module 70 through the elastic connection of the elastic buffer or the rigid connection.

[0199] In addition to saving the space for setting the air duct to achieve miniaturization, the peripheral space around the small drum can also be miniaturized by setting a drying module or a delivery function module around the small drum. In the multi-drum laundry processing device, with the axis extending in the front-to-back direction through the rotation center of the first large drum 10 as the center line, when viewed from the front, at least a part of the drying module or at least a part of the delivery function module is set on the side opposite to the small drum relative to the center line.

[0200] As a result, not only the space around the small drum is utilized, but the drying module arranged around the small drum is also used as a counterweight to balance the center of gravity of the whole multi-drum clothing processing device, thereby suppressing the vibration of the multi-drum clothing processing device when the clothing processing drum (including the large drum and the small drum) rotates. At the same time, this arrangement method can make the drying module relatively close to each drum, which is conducive to shortening the drying airflow path and reducing the heat and air volume loss in the process of conveying the drying airflow.

[0201] In the case where the drying module is a heat pump drying module, it is preferred that at least two of the compressor, condenser, evaporator, and fan of the drying module are located on the side opposite to the small tube. It is also preferred that the compressor is located behind the small tube, and the condenser, evaporator, and fan are located on the side opposite to the small tube relative to the center line. Such a structure can effectively utilize the space around the small tube while better balancing the center of gravity of the device.

[0202] When the drying module is an electric heating drying module, preferably, at least one of the electric heater and the fan of the drying module is located on the side opposite to the small tube. Such a structure can effectively utilize the space around the small tube and better balance the center of gravity of the device.

[0203] The same is true for the case where the delivery function module is set in the space around the small barrel. The delivery function module has at least one of a replaceable clothing treatment agent box, a cavity that can be pre-filled with clothing treatment agent, and a pump part for automatically supplying clothing treatment agent. When viewed from the front, relative to the center line O, at least one of the replaceable clothing treatment agent box, the cavity, and the pump part is located on the side opposite to the small barrel. As in the case of setting the drying module, when the delivery function module is set, the space around the small barrel can also be used flexibly and the center of gravity of the device can be better balanced, and the vibration of the multi-barrel clothing treatment device when the clothing treatment barrel (including the large barrel and the small barrel) rotates can be suppressed. At the same time, the arrangement method can make the delivery function module relatively close to each barrel, which is conducive to shortening the delivery path, reducing the power requirements required for delivery, and reducing the residual and waste of the delivery agent in the delivery pipeline. Preferably, when viewed from the front, an opening for pre-filling clothing treatment agent into the delivery function module or replacing the replaceable clothing treatment agent box is provided at the side of the machine door of the small barrel of the box assembly. Since the opening is provided at the side of the door of the small drum, it is possible to easily fill the laundry treatment agent or replace the laundry treatment agent box.

[0204] The above structure can make full use of the peripheral space of the small barrel, improve the utilization rate of the space, and use at least a part of the drying module and at least a part of the delivery function module as a counterweight, so as to move the overall center of gravity to the central side of the multi-barrel clothing processing device, and the vibration caused by the rotating inner barrel of the small barrel can be suppressed to a certain extent. Therefore, the special counterweight block for the small barrel can be eliminated or reduced. In addition, at least a part of the drying module or at least a part of the delivery function module and the small barrel can also serve as the counterweight of the large barrel located above and / or below the two, and the special counterweight block for the large barrel can be eliminated or reduced. As a result, it is conducive to miniaturization of the multi-barrel clothing processing device.

[0205] Since the drying module or the delivery function module is arranged around the small drum, and is below the first large drum 10 and above the second large drum 40, the distance from the drying module or the delivery function module to each clothing processing drum can be shortened, thereby improving the drying efficiency of the drying module or the delivery efficiency of the delivery function module.

[0206] The structures described above can be used in conjunction with each other without conflict. For example, even if the air inlet duct 80 is set between the first small tube 20 and the second small tube 30 to save the air supply duct setting space (refer to Fig.24 ), it is still possible to set a connecting plate 58 between the first small tube 20 and the second small tube 30 (refer to Fig.23), the air inlet duct 80 is set to make use of the space between the first small tube 20 and the second small tube 30, but will not completely occupy the space between the first small tube 20 and the second small tube 30, so the connecting plate 58 can still be set to connect the first small tube 20 and the second small tube 30 as a whole. Those skilled in the art can arbitrarily combine the various components in the technical solution of the present application under the premise that the various structures do not conflict with each other.
