Description

TECHNICAL FIELD

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

[0002] With the progress of the washing machine industry technology and the improvement of people's cleaning awareness, consumers pay more and more attention to the health washing of washing machines, especially for the mother and baby groups. Consumers gradually begin to separate underwear, socks, and large category of clothes for washing, and the demand for zoned cleaning of small and close-fitting clothes / baby clothes is also increasing. Therefore, a multi-cylinder washing machine is needed for zoned cleaning. At present, there are only double-zoned washing / drying machines or single small-cylinder laundry treating devices or devices composed of one large-cylinder laundry treating device and one small-cylinder laundry treating device on the market. If the underwear / underwear / socks or baby clothes need to be processed separately, more zones are expected.

[0003] For a double-zoned laundry treating apparatus composed of two large-cylinder laundry treating devices, when there is a demand for the use of an additional small-cylinder laundry treating device, if the existing suspension support is used as in the device composed of one large-cylinder laundry treating device and one small-cylinder laundry treating device, the small-cylinder laundry treating device can be set between the two large-cylinder laundry treating devices, although the vibration of the small cylinder can be inhibited, but it will inevitably lead to the overlarge height of the device in the up-down direction. Therefore, for the case of additionally adding one or more small-cylinder laundry treating devices in the double-zoned laundry treating apparatus composed of two large-cylinder laundry treating devices, a connecting structure is needed that can not only inhibit the vibration caused by the rotation of the small-cylinder laundry treating device to a certain extent, but also take into account the miniaturization.

DETAILED DESCRIPTION

[0073] Hereinafter, the embodiments of the present application will be described based on the drawings. It should be noted that the following description and the drawings are merely one example of the present application, and are not intended to limit the present application in the absence of specific description. In the following description, the embodiments of the present application will be described with reference to the drawings. Figure 1 ​The side on which the openings of the laundry treatment barrels (the first large barrel 10, the first small barrel 20, the second small barrel 30, the second large barrel 40) are located is referred to as the front side, the side opposite to the openings of the laundry treatment barrels is referred to as the rear side, the side on which the first large barrel 10 is located is referred to as the upper side, the side on which the second large barrel 40 is located is referred to as the lower side, the side on which the first small barrel 20 is located is referred to as the left side, and the side on which the second small barrel 30 is located is referred to as the right side.

[0074] <Overall structure of the multi-barrel laundry treatment apparatus>

[0075] As shown in Figure 1 , as a typical example, the multi-barrel laundry treatment apparatus 100 of the present application can be a laundry treatment apparatus including four laundry treatment barrels (the first large barrel 10, the first small barrel 20, the second small barrel 30, the second large barrel 40).

[0076] The front view of the multi-barrel laundry treatment apparatus 100 is shown in Figure 1 , which includes a cabinet assembly 1 that constitutes the skeletal structure of the multi-barrel laundry treatment apparatus 100 using a frame and forms a cavity space inside the multi-barrel laundry treatment apparatus 100 by mounting a metal plate or a plate-shaped body of other material, which is not shown, on the frame to constitute the outer contour of the multi-barrel laundry treatment apparatus 100, a first large barrel 10 disposed on the upper side (i.e., the upper portion) of the cavity space in the cabinet assembly 1, a second large barrel 40 disposed on the lower side (i.e., the lower portion) of the cavity space in the cabinet assembly 1, and first and second small barrels 20 and 30 having an outer diameter smaller than those of the first and second large barrels 10 and 40, which are disposed in the cabinet assembly 1 at a position between the first and second large barrels 10 and 40 in the cavity space by a connection device 50, which will be described later, as shown in Figure 1 , in the vertical direction, the first and second small barrels 20 and 30 are located below the first large barrel 10 and above the second large barrel 40, and are approximately in the middle of the multi-barrel laundry treatment apparatus 100 in the vertical direction.

[0077] <Support structure of the laundry treatment barrels>

[0078] As the laundry treating drum, the present application, for example, on the basis of including the first large drum 10 and the second large drum 40, further includes at least one small drum (at least any one of the first small drum 20 and the second small drum 30). Thereby, the present application can treat different types of laundry using a plurality of laundry treating drums, and for the laundry treating drum, not only can a plurality of laundry treating drums be selectively used according to the type of laundry (for example, the size of laundry, the material of laundry, whether the laundry is worn outside, and various factors), but also can be selectively used according to the different wearers of the laundry (for example, adults, children, the elderly, patients, special professionals, and various factors). However, on the other hand, since the existing multi-drum laundry treating apparatus does not give clear disclosure on the connecting apparatus when a small drum is added to the laundry treating apparatus having a large drum above and below, if a large drum is added based on the existing apparatus having only one large drum and one small drum, it cannot be avoided that the large drum is large.

[0079] The present inventors have found, as a result of diligent research, that for a laundry treating apparatus having an upper and lower partitioned large drum, by providing at least one small drum between the two large drums using an elastic damping body in a compressive stress manner, the vibration of the small drum when rotating can be well suppressed without additionally providing other elastic suspension apparatuses (for example, a tensile stress member such as a spring), thereby achieving miniaturization while suppressing vibration compared to the conventional structure.

[0080] In addition, for the existing apparatus having only one large drum and one small drum, if another large drum is directly added, the inlet of the large drum above becomes very high, and it is not easy for the user to perform the operation of putting in laundry, etc. Here, by not using the ordinary way of hanging the small drum on the cabinet using a hanging spring, etc., the space can be saved to a greater extent. As a result, especially for the structure of the present application having a large drum above and below and having one small drum in the middle, the space occupied by the fixation of the small drum can be significantly reduced, and the space is facilitated.

[0081] In addition, for the first large drum 10 and the second large drum 40, the existing suspension apparatus can be used to support the cabinet assembly 1.

[0082] <First Embodiment>

[0083] In Figure 2 , it is shown that the first small drum 20 and the second small drum 30 are connected to the support 60 by the connecting apparatus 50, and the support 60 is supported by the cabinet assembly 1. Figure 2The figure shows a structure in which the support member 60 is located below the first small cylinder 20 and the second small cylinder 30, but it is not limited to this. Without 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.

[0084] like Figure 5 As shown, the support member 60 has a protrusion 61 for installing the connecting device 50, an opening 63 is provided in the protrusion 61, and a rising portion 62 is provided around the opening 63. The direction in which the protrusion 61 protrudes relative to the support member 60 is opposite to the direction in which the rising portion 62 rises relative to the protrusion 61.

[0085] exist Figure 3 FIG shows a top view of the structure supporting the first small cylinder 20 and the second small cylinder 30. Figure 4 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.

[0086] Reference Figure 5-7 , the connection device 50 according to the first embodiment will be described.

[0087] like Figure 6 、 Figure 7 As shown, the connecting device 50 includes: a gasket 51 having a through hole in the center; a first elastic body 52, which is roughly cylindrical, and 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 at its center that passes through the entire first elastic body 52; a second elastic body 53 has 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 of the first elastic body 51 relative to the second base 531, and the second elastic body 53 has a second through hole 533 at its center that passes through the entire second elastic body 53; and a gasket 54 having a through hole in the center. 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 connecting device 50 also includes fasteners such as screws (not shown).

[0088] Reference Figure 8-10The first small cylinder 20 (the second small cylinder 30) of the first embodiment will be described.

[0089] As shown in Figure 8 , the (outer cylinder of the) first small cylinder 20 is divided into a front cylinder 21 and a rear cylinder 22 in the front-rear direction, and the (outer cylinder of the) second small cylinder 30 is divided into a front cylinder 31 and a rear cylinder 32 in the front-rear direction. The first small cylinder 20 and the second small cylinder 30 have the same structure, and thus, only the first small cylinder 20 will be described below, and the description of the second small cylinder 30 will be omitted.

[0090] As shown in Figure 9 , the front cylinder 21 has downwardly protruding insertion portions 211, 212, and has screw holes 213, 214 at the top ends of the insertion portions 211, 212. As shown in Figure 10 , the rear cylinder 22 has downwardly protruding insertion portions 221, 222, and has screw holes 223, 224 at the top ends of the insertion portions 221, 222.

[0091] Returning again to Figure 5 , the arrangement of the first small cylinder 20 and the connecting device 50 will be described. The connection structure at each of the insertion portions 211, 212, 221, 222 is the same, and thus, only the connection structure at the insertion portion 212 will be described below as an example.

[0092] As shown in Figure 5 , the insertion portion 212 of the first small cylinder 20 is first inserted into the gasket 51, and then the insertion portion 212 of the first small cylinder 20 is further inserted into the first elastic body 52 in such a manner that one end (a substantially flat end) of the first elastic body 52, which is not formed with the first protruding portion 522, abuts against the gasket 51, until the insertion portion 212 of the first small cylinder 20 penetrates 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 protruding portion 522.

[0093] As shown in Figure 5 , the insertion portion 212 of the first small cylinder 20 is inserted into the opening 63 of the protrusion 61 together with the first protruding portion 522 of the first elastic body 52 from the upper side of the support member 60 (one side of the support member 60) Figure 5 , and the protruding degree of the first protruding portion 522 relative to the first base portion 521 corresponds to the sum of the wall thickness of the protrusion 61 and the standing-up degree of the standing-up portion 62 relative to the protrusion 61.

[0094] As shown in Figure 5 , the insertion portion 212 of the first small cylinder 20 is inserted into the opening 63 of the protrusion 61 together with the first protruding portion 522 of the first elastic body 52 from the upper side of the support member 60 (one side of the support member 60) Figure 5The second elastic body 53 and the spacer 54 are sequentially installed in the lower side of the first small 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 protruding portion 522 and the standing portion 62 are opposed to the second base portion 531 of the second elastic body 53 in the vertical direction, the second protruding portion 532 of the second elastic body 53 is in abutment with the convex portion 61 with the first base portion 521 of the first elastic body 52 sandwiching the convex portion 61 in the vertical direction. In Figure 5 the left-right direction, the second protruding portion 532 of the second elastic body 53 is opposed to the first protruding portion 522 of the first elastic body 52 with the standing portion 62 interposed therebetween. The second base portion 531 is opposed to the standing portion 62 in the standing direction (vertical direction) of the standing portion 62, and the second protruding portion 532 is opposed to the standing portion 62 on the outer peripheral side of the standing portion 62. Although not shown, the second protruding portion 532 can be opposed to the standing portion 62 on the inner peripheral side of the standing portion 62.

[0095] In Figure 5 , a threaded member (one example of a fastener) is not shown, but in actual installation, by inserting the unshown threaded member into the through-hole of the spacer 54 and further into the screw hole 214 of the insertion portion 212, and performing threaded fastening, the threaded member is passed through the support member 60 and the second elastic body 53 and the first elastic body 52, and is fastened to the first small cylinder 20. By the above structure, the first small cylinder 20 is installed to the support member 60 via the connecting device 50, and after the fastener is passed through the support member 60 and the elastic damper (the first elastic body 52, the second elastic body 53) and is fastened to the small cylinder (the first small cylinder 20, the second small cylinder 30), the small cylinder can be firmly and elastically supported to the elastic damper of the connecting device and the support member by the fastener. Further, in Figure 2 , a structure in which four portions below the first small cylinder 20 (the second small cylinder 30) are installed to the support member 60 via the connecting device 50 is shown. However, the positions and the number of the connecting device 50 to be provided are not limited to Figure 2 shown, and the positions (i.e., the positions of the insertion portions provided on the small cylinder) and the number of the connecting device 50 to be provided can be arbitrarily changed as long as the first small cylinder 20 (the second small cylinder 30) can be stably supported.

[0096] Further, the support member 60 can not be provided, and the first small cylinder 20 and the second small cylinder 30 can be directly supported to the cabinet assembly 1 by the connecting device 50.

[0097] In the present embodiment, by having the multi-cylinder laundry treating device with the first large cylinder, the second large cylinder and at least one small cylinder, the capacity of treating laundry can be significantly increased compared to the device with only one large cylinder and one small cylinder. By mounting the first small cylinder 20 and the second small cylinder 30 to the support 60 or the cabinet assembly 1 through the connecting device 50, when the first small cylinder 20 and the second small cylinder 30 rotate, the first elastic body 52 of the connecting device 50 is compressed under the action of the compressive stress, thereby absorbing the vibration generated when the first small cylinder 20 and the second small cylinder 30 rotate, achieving the effect of inhibiting vibration. In addition, in the prior art field, the use of suspension springs to inhibit the vibration of the drum has formed a technical habit, but the inventors of the present application have found that for such a multi-cylinder laundry treating device of the present application which is divided into upper and lower zones, by not using a spring or the like based on the principle of tensile stress to inhibit vibration between the first large cylinder 10 and the second large cylinder 40, but using the first elastic body 52 (i.e. elastic damping body) which elastically supports the first small cylinder 20 and the second small cylinder 30 in a compressed manner, the inhibition of vibration can still be achieved, and the miniaturization in the vertical direction can also be achieved by not using suspension springs.

[0098] Hereinafter, other embodiments of the present application will be described, and for the same constituent elements as the first embodiment, the corresponding description will be omitted.

[0099] <Second Embodiment>

[0100] Hereinafter, the second embodiment will be described based on Figure 11-16

[0101] In Figure 11 , a sectional view of the part corresponding to Figure 4 is shown. In Figure 12 , a perspective view of the support 60a is shown, as shown in Figure 12 , a through hole 62a is formed on the convex part 61a, and as shown in Figure 13 , an opening 63a is also formed on the convex part 61a.

[0102] The connecting device 50a of the second embodiment will be described with reference to Figure 13 , Figure 14 .

[0103] In Figure 13 , an enlarged view of the part enclosed by the dashed line frame in Figure 11 is shown. The connecting device 50a of the second embodiment has an elastic body 51a which has a through hole 53a passing through the elastic body 51a at its center, metal parts are connected at both ends of the elastic body 51a which is an intermediate part, and through holes are formed in the metal parts corresponding to the through hole 53a of the elastic body 51a to communicate therewith.​

[0104] In Figure 14 , a perspective view of the elastic body 51a is shown. The outer peripheral portion of the metal portion at one end of the elastic body 51a has, for example, two flange portions, and one through-hole 54a is formed in each of the two flange portions.

[0105] Referring to Figure 15 , Figure 16 , the first small cylinder 20a (the second small cylinder 30a) of the second embodiment will be described.

[0106] As in the first embodiment, the first small cylinder 20a (the outer cylinder thereof) is divided into a front cylinder 21a and a rear cylinder 22a in the front-rear direction, and the second small cylinder 30a (the outer cylinder thereof) is divided into a front cylinder and a rear cylinder in the front-rear direction. The first small cylinder 20a and the second small cylinder 30a have the same structure, and therefore, only the first small cylinder 20a will be described below, and the description of the second small cylinder 30a will be omitted.

[0107] As Figure 15 shown, the front cylinder 21a has protruding portions 211a, 212a protruding downward, and has screw holes 213a, 214a at the top ends of the protruding portions 211a, 212a. As Figure 16 shown, the rear cylinder 22a has protruding portions 221a, 222a protruding downward, and has screw holes 223a, 224a at the top ends of the protruding portions 221a, 222a.

[0108] Returning again to Figure 13 , the arrangement of the first small cylinder 20a and the connecting device 50a will be described. The connection structure at each of the protruding portions 211a, 212a, 221a, 222a is the same, and therefore, only the connection structure at the protruding portion 212a will be described below as an example.

[0109] As Figure 13 shown, the elastic body 51a is interposed between the protruding portion 212a of the first small cylinder 20a and the convex portion 61a of the support member 60a in such a manner that the through-hole 53a of the elastic body 51a is coaxial with the screw hole 214a of the protruding portion 212a and the opening 63a. Also, the two through-holes 54a of the elastic body 51a are opposed to the two through-holes 62a of the convex portion 61a, respectively, and therefore, the elastic body 51a can be stably fixed to the convex portion 61a by a screw.

[0110] In Figure 13A threaded member (an example of a fastener) is not shown, but in actual installation, by inserting the threaded member, which is not shown, into the opening 63a of the protrusion 61a and further through the through-hole 53a of the elastic body 51a, into the screw hole 214a of the protruding portion 212a, and performing threaded fastening, the first small drum 20a is installed to the support member 60a via the connecting device 50a. By the above structure, the first small drum 20a is installed to the support member 60a via the connecting device 50a. Further, as in the first embodiment, the number and position of the connecting devices 50a are not particularly limited, as long as the first small drum 20a (the second small drum 30a) can be stably supported.

[0111] <3rd Embodiment>

[0112] In Figure 17 , a perspective view of the structure of the small drum support of the 3rd embodiment is shown.

[0113] In the multi-drum laundry treating apparatus of the 3rd embodiment, in addition to the connecting device 50b, a 2nd connecting device 55 is provided, the 2nd connecting device 55 includes an elastic body, and the 2nd connecting device 55 can elastically support the support member 60b by being compressed when the small drum rotates, thereby helping to suppress the vibration of the small drum. Further, the connecting device 50b is also a structure for suppressing the vibration of the small drum based on compressive stress, i.e., includes an elastic damping body that can be deformed in a compressed manner when the small drum rotates.

[0114] In Figure 17 , an enlarged view of the structure of connecting the support member 60b and the cabinet assembly 1b via the 2nd connecting device 55 is shown. The support member 60b in the 3rd embodiment is connected to the cabinet assembly 1b at one end thereof in the lengthwise direction (left-right direction). The 2nd connecting device 55 is interposed between the support member 60b and the cabinet assembly 1b. According to the 3rd embodiment, in addition to suppressing the vibration by the connecting device 50b when the small drum rotates, the 2nd connecting device 55 can also be used to suppress the transmission of the vibration transmitted to the support member 60b to the cabinet assembly 1b. Thus, the vibration can be further suppressed, and the structure of the 2nd connecting device 55 can achieve miniaturization.

[0115] <4th Embodiment>

[0116] In Figure 18 , a perspective view of the structure of the small drum support of the 4th embodiment is shown.

[0117] In the multi-cylinder laundry treating apparatus of the fourth embodiment, a support member 60c is provided in correspondence with the shape of the first small cylinder 20, so that the support member 60c is disposed so as to surround the outer periphery of the first small cylinder 20 with a space between the support member 60c and the first small cylinder 20. In the substantially annular space between the support member 60c and the first small cylinder 20, a plurality of elastic bodies of the connecting means 50c are arranged along the outer periphery of the first small cylinder 20. Further, the interval between the plurality of elastic bodies is not particularly limited, as long as the vibration can be absorbed by compression in the up-down and left-right directions with the rotation of the small cylinder.

[0118] An opening is formed in the portion of the support member 60c corresponding to the connecting means 50c, through which the connecting means 50c penetrates. The connecting means 50c can be an elastic body integrally formed, or an elastic body formed in parts and combined together from both the inner and outer sides of the support member 60c. The small cylinder can be directly connected to the cabinet assembly 1 by means of the connecting means 50c, or connected to the cabinet assembly 1 by means of the support member 60c.

[0119] When the first small cylinder 20 rotates, the first small cylinder 20 generates vibration in the up-down or left-right direction with the rotation. Since the connecting means 50c in the substantially annular space between the support member 60c and the first small cylinder 20 are uniformly distributed in the up-down and left-right directions of the first small cylinder 20, the connecting means 50c are compressed to suppress the vibration when the first small cylinder 20 vibrates in the up-down or left-right direction.

[0120] Therefore, the structure of the fourth embodiment can also well suppress the vibration and achieve miniaturization.

[0121] <5th Embodiment>

[0122] In Figure 19 , Figure 20 , a perspective view of the structure of the small cylinder support of the fifth embodiment is shown.

[0123] In the multi-cylinder laundry treating apparatus of the fifth embodiment, a support member 60d is provided in correspondence with the shape of the first small cylinder 20, so that the support member 60d is disposed so as to surround the outer periphery of the first small cylinder 20 with a space between the support member 60d and the first small cylinder 20. In the substantially annular space between the support member 60d and the first small cylinder 20, connecting means 50dl, 50d2 are provided so as to extend in the circumferential direction along the outer periphery of the first small cylinder 20.

[0124] In Figure 20 , the structure after the support member 60d is removed is shown. As Figure 20As shown, the connection device 50d1 surrounds the first small drum 20 over the entire circumference, and the connection device 50d2 is provided at the rear of the connection device 50d1 so as to surround a large portion (for example, 80% or more of the entire circumference) of the first small drum 20.

[0125] Specifically, the outer circumference of the front drum of the first small drum 20 is circular (see FIG. 6A), the connection device 50d1 is in the shape of a circular ring so as to cover the front drum of the first small drum 20, the outer circumference of the rear drum of the first small drum 20 is in the shape of a circle having a protrusion at the lower side (see FIG. 6B), and the connection device 50d2 is formed on the outer circumference of the rear drum of the first small drum 20 so as to avoid the protrusion, thereby having the shape of a circular ring having a notch, that is, a continuous substantially C shape. Of course, the connection devices 50d1 and 50d2 are not limited thereto, and can be in the shape of a circular ring or a substantially C shape. In any case, the connection device of the fifth embodiment is an embodiment in which the continuous elastic body is in the shape of a circular ring or a substantially C shape. Figure 9 Figure 15 Figure 10 Figure 16 The thickness of the connection devices 50d1 and 50d2 is substantially equal to or slightly greater than the distance between the support 60d and the first small drum 20. The front-rear direction length of the connection device 50d2 is greater than the front-rear direction length of the connection device 50d1.

[0126] Thus, when the first small drum 20 rotates, the connection device 50d1, which is an elastic body and surrounds the first small drum 20 over the entire circumference, and the connection device 50d2, which is an elastic body and surrounds a large portion of the first small drum 20, can be reliably compressed as the first small drum 20 rotates, thereby suppressing vibration during rotation, and miniaturization can be achieved.

[0127] <6th Embodiment>

[0128] In

[0129] In Figure 21 Figure 22 A perspective view of the structure of the support small drum of the sixth embodiment is shown.

[0130] In the multi-drum laundry treating apparatus of the sixth embodiment, the support 60e has a shape that matches the shape of the first small drum 20, and thus the support 60e is provided so as to surround the first small drum 20 on the outer circumference of the first small drum 20 with a gap between the support 60e and the first small drum 20. The connection devices 50e1 and 50e2 are provided in the substantially circular ring-shaped space between the support 60e and the first small drum 20.

[0131] In Figure 22 ​​​​The structure after the support member 60e is removed is shown in FIG. Figure 22 As shown, connecting device 50e1 is based on connecting device 50d1 of the fifth embodiment, except that the elastic member of connecting device 50e1 is arc-shaped, and multiple arc-shaped elastic members are intermittently arranged on the outer periphery of the front tube in the circumferential direction. Connecting device 50e2 is based on connecting device 50d2 of the fifth embodiment, except that the elastic member of connecting device 50e2 is arc-shaped, and multiple arc-shaped elastic members are intermittently arranged on the outer periphery of the front tube in the circumferential direction. The front-to-back length of connecting device 50e2 is greater than that of connecting device 50e1.

[0132] 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.

[0133] Similarly, when the first small cylinder 20 rotates, the connecting devices 50e1 and 50e2 intermittently arranged along the circumference of the first small cylinder 20 can be compressed as the first small cylinder 20 rotates, thereby suppressing vibration during rotation and achieving miniaturization.

[0134] 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 being able to more reliably elastically support the small cylinder and absorb the vibration caused by the rotation of the small cylinder.

[0135] <Seventh embodiment>

[0136] exist Figure 23 , a three-dimensional view of the structure of the supporting small cylinder of the 7th embodiment is shown.

[0137] 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. Figure 23 As shown, an elastic vibration damping sheet 56 is connected to the outside of the first small cylinder 20 (outer cylinder) (i.e., the side of the first small cylinder 20 opposite to the second small cylinder 30). The elastic vibration damping sheet 56 is plate-shaped and extends in the vertical direction. The upper and lower ends of the elastic vibration damping sheet 56 are connected to the box assembly 1 via elastic bodies 57 (elastic damping bodies). The same arrangement is made for the second small cylinder 30 (refer to Figure 23), the description of the elastic damper 56 provided for the second small cylinder 30 is omitted, and the technical effects described below for the first small cylinder 20 can be equally applied to the second small cylinder 30.

[0138] With this structure, the left-right direction vibrations of the first small cylinder 20 during rotation can be absorbed by the elastic damper 56. Preferably, the first small cylinder 20 is connected to the elastic damper 56 at the portion of the first small cylinder 20 closest to the cabinet assembly 1 (i.e., the leftmost side of the first small cylinder 20 in the cabinet assembly 1), and the portion of the first small cylinder 20 connected to the elastic damper 56 is located at the middle position of the elastic damper 56 in the up-down direction. In this way, the vibrations from the first small cylinder 20 can be uniformly transmitted to the elastic damper 56, preventing the upper and lower portions of the elastic damper 56 from being deflected to different degrees and failing to absorb the vibrations well. Alternatively, for one elastic damper 56, the first small cylinder 20 can be connected to the one elastic damper 56 at multiple positions, and the multiple connection positions can be symmetric to each other with respect to the middle position of the elastic damper 56 in the up-down direction, so that the vibrations from the first small cylinder 20 can also be uniformly transmitted to the elastic damper 56. Figure 23 For the first small cylinder 20, multiple elastic dampers 56 can be provided, and the multiple elastic dampers 56 can be arranged along the front-rear direction (depth direction) of the first small cylinder 20 and outside the first small cylinder 20 (between the first small cylinder 20 and the cabinet assembly 1). In this way, the vibrations of the first small cylinder 20 can be more reliably absorbed, and the effect of absorbing the vibrations can be further improved.

[0139] For the connection of the elastic damper 56 to the cabinet assembly 1, the elastic damper 56 can be connected to the cabinet assembly 1 via an elastic body 57 (elastic damping body), so that the vibrations can be absorbed not only by the elastic damper 56 but also by the elastic body 57, and the effect of absorbing the vibrations can be further improved. However, the elastic body 57 can not be provided, i.e., the elastic damper 56 can be rigidly connected to the cabinet assembly 1. In addition, the elastic damper 56 can not extend in the up-down direction but extend in the front-rear direction, i.e., in the same direction as the depth direction of the first small cylinder 20.

[0140] As shown in FIG. 2, a connecting plate 58 can be provided between 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 connected as a whole, and the vibrations of the first small cylinder 20 and the second small cylinder 30 can be better damped, e.g., the left-right direction vibrations of the first small cylinder 20 can be damped not only by the elastic damper 56 on the first small cylinder 20 side but also by the elastic damper 56 on the second small cylinder 30 side.

[0141] Figure 23

[0142] ​​In the present embodiment, the elastic vibration-damping sheet 56 that connects the small cylinder to the cabinet assembly 1 is provided on the side closest to the cabinet assembly 1 (the left side of the first small cylinder 20, the right side of the second small cylinder 30) in the one or more small cylinders (for example, the first small cylinder 20, the second small cylinder 30, and possibly more small cylinders). That is, in the case of having only one small cylinder, the elastic vibration-damping sheet 56 can be provided on at least either of the left and right sides of the one small cylinder, and preferably on both the left and right sides. In the case of having multiple small cylinders, the elastic vibration-damping sheet 56 can be provided between the small cylinder closest to the cabinet assembly 1 and the cabinet assembly among the multiple small cylinders.

[0143] 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 in combination with other embodiments, and the different forms of the connecting device in the first embodiment, the second embodiment, and the fourth to sixth embodiments can be used in combination as long as they do not conflict with each other. In addition, in the fourth to sixth embodiments, it is preferable that the support member surround the small cylinder so that the small cylinder can be more reliably supported by the support member, but the support member can not surround the small cylinder.

[0144] [Other]

[0145] The elastic body in each of the above-described embodiments is an elastic damping body, and is preferably one of a rubber damping body, an air damping vibration damper, a hydraulic damping device, and a metal damper. By selecting a commercially available elastic body, the versatility of the parts used in the device can be improved.

[0146] The fastener of the connecting device can not be provided through the support member and the elastic damping body, or a plurality of fasteners can be provided at both ends of the elastic damping body, and the plurality of fasteners can extend from the elastic damping body in 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 member (or the cabinet assembly), the small cylinder can be elastically supported by the support member or the cabinet assembly, and the vibration of the small cylinder due to rotation can be absorbed by compressing the elastic damping body. Thus, the small cylinder can also be firmly elastically supported by the elastic damping body of the connecting device by means of the fastener, and the elastic damping body of the connecting device can also be firmly supported by the support member by means of the fastener. Here, the case where a plurality of fasteners are provided at both ends of the elastic damping body includes not only a structure in which the fasteners are provided at both ends with an elastic body (for example, a rubber elastic body) interposed therebetween, and the plurality of fasteners are fixed to the support member (or the cabinet assembly) and the small cylinder by nuts, respectively, but also a structure in which, in the case of a metal damper, the upper portion of the metal damper is fixed to the small cylinder by a fastener, and the lower portion of the metal damper is fixed to the support member (or the cabinet assembly) by another fastener.

[0147] The large drum and the small drum as the laundry treating drum generally have an inner drum rotatable and an outer drum fixed and non-rotatable. The front drum and the rear drum described in the above description refer to the front drum and the rear drum of the outer drum. In the above embodiment, the first small drum 20 and the second small drum 30 are connected to one support member 60 via the plurality of connection devices 50, and connected to the cabinet assembly 1 via the one support member 60. However, it is not limited thereto, and the first small drum 20 and the second small drum 30 can be connected to a plurality of support members 60 via the plurality of connection devices 50, and connected to the cabinet assembly 1 via the plurality of support members 60. Alternatively, the first small drum 20 and the second small drum 30 can be connected to different support members 60 via the plurality of connection devices 50, i.e., the first small drum 20 is connected to the cabinet assembly 1 via one or more support members 60, and the second small drum 30 is connected to the cabinet assembly 1 via other one or more support members 60. By connecting the plurality of small drums to the cabinet assembly via the plurality of connection devices, respectively, the elastic support for the plurality of small drums can be reliably performed, respectively. If the support members are further provided on the basis of the connection devices, the connection devices can be more easily supported, and even the portions of the outer periphery of the small drums which are difficult to be connected to the cabinet assembly can be connected to the cabinet assembly via the support members. In summary, as long as the first small drum 20 and the second small drum 30 can be well supported, it is acceptable whether both of the small drums are directly connected to the cabinet assembly 1, or are flexibly connected to the cabinet assembly 1 via the same support members, different support members, or partially the same support members, or are connected to the cabinet assembly 1 and the support members 60, respectively.

[0148] Alternatively, the first small drum 20 and the second small drum 30 can have respective inner drums rotatable, and a common outer drum surrounding the respective inner drums, and the outer drum can have a barrel shape. In this case, the connection of the barrel-shaped outer drum to the cabinet assembly 1 and / or the support members 60 is performed using the connection devices 50. Alternatively, the first small drum 20 and the second small drum 30 can have separate outer drums, instead of the common outer drum. In this case, the outer drums of the first small drum 20 and the second small drum 30 are connected to each other using a connection member, and the connected outer drum (the first small drum 20 and the second small drum 30) is connected to the cabinet assembly 1 and / or the support members 60 via the connection devices 50. By integrally forming or connecting the plurality of small drums, the support for the plurality of small drums can be uniformly performed, and the elastic support for the plurality of small drums can be reliably performed.

[0149] The following describes the peripheral structure of the laundry processing drum (particularly referring to the first small drum 20 and the second small drum 30, but not limited to the two small drums). The peripheral space of the laundry 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 drums and the housing assembly (to the sides of the first small drum 20 and the second small drum 30). By effectively utilizing the peripheral space of the laundry processing drum, the multi-drum laundry processing device of the present application can be constructed more compactly. This complements the structure of elastically supporting the small drums using the connecting device, and the coordinated structures can further achieve miniaturization.

[0150] exist Figure 24 、 Figure 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. Figure 26 3 shows the peripheral structure of the clothes processing drum of the present application when the first large drum 10, the first small drum 20, the second small drum 30 and the second large drum 40 are completely removed.

[0151] like Figure 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. As Figure 25 As shown, an air outlet connection portion 91 serving as a portion of an air outlet duct 90 is provided on the rear side of the first small tube 20 .

[0152] exist Figure 26 In the figure, the first small cylinder 20 and the second small cylinder 30 are removed. Figure 26As can be seen, the drying module 70 is arranged at the rear side of the first small drum 20 and the second small drum 30. The drying module 70 is arranged between the first large drum 10 and the second large drum 40 in the up-down direction. The drying module 70 occupies most of the space at the rear side of the first small drum 20 and the second small drum 30, and the air outlet connecting portion 91, which is part of the air outlet duct 90, occupies a small part of the space at the rear side of the first small drum 20 and the second small drum 30, and the drying module 70 and the air outlet connecting portion 91 of the air outlet duct 90 are arranged in the left-right direction and communicate with each other. Thus, the space at the rear side of the first small drum 20 and the second small drum 30 can be fully utilized, and the first small drum 20, the second small drum 30, the drying module 70, at least part of the air inlet duct 80, and at least part of the air outlet duct 90 are arranged simultaneously in the horizontal direction of the space where the first small drum 20 and the second small drum 30 are arranged, so that a compact layout of the peripheral structure of the laundry treatment drum is achieved.

[0153] The following describes the structure of the drying module 70, the air inlet duct 80, and the air outlet duct 90 based on Figure 27-31 .

[0154] <DRYING MODULE>

[0155] The drying module 70 is used to heat air to generate drying air. As shown in Figure 27 , the drying module 70 has an upper shell and a lower shell, and the components such as a compressor, an evaporator, a condenser, etc. that are not shown are accommodated in the interior of the drying module 70 by the upper shell and the lower shell being engaged with each other. Of course, the compressor does not necessarily have to be arranged in the interior of the drying module 70, and the compressor can be arranged on the lower shell without the upper shell being engaged to cover it.

[0156] An opening 71 is formed in the front portion of the drying module 70 in the front-rear direction, i.e., in the wall portion opposite to the first small drum 20 and the second small drum 30 in the front-rear direction, and in the example shown in Figure 27 , the opening 71 is formed in the upper shell, but it can also be formed in the lower shell, which is not limited. As shown by the arrow in Figure 27 , air from the laundry treatment drum (large drum and / or small drum) is guided to the drying module 70, and the air is heated in the drying module 70 to generate drying air. In this embodiment, the opening 71 is connected to the air inlet connecting portion 85 (see Figure 30 ) of the air inlet duct 80 described below, so that the air can be sent to the drying module 70.

[0157] In Figure 28 , a perspective view of the drying module 70 is shown as viewed from the rear side (the side opposite to the first small drum 20 and the second small drum 30). And in Figure 28The driving portion is omitted from the illustration. The driving portion can be provided at a mounting portion of the upper portion of the housing of the drying module 70 and used to drive the rotation of the rotating drum in the first large drum 10. By using the upper portion of the housing of the drying module 70 as the mounting portion for mounting the driving portion, it is not necessary to additionally provide a mounting portion for mounting the driving portion, and miniaturization in the up-down direction can also be achieved. It is more preferable to provide the mounting portion as a recess, as shown in Figure 28 , in which the upper portion of the upper housing facing upward has a recess for mounting the driving portion, and Figure 27 , in which the structure of the driving portion mounted in the recess is shown. By providing the recess in the drying module 70 to mount the driving portion, further miniaturization in the up-down direction can be achieved.

[0158] In addition, in Figure 28 , the lower housing has an opening 72 for sending out the drying gas generated in the drying module 70, i.e., the air in the laundry treatment drum is guided into the drying module 70 via the opening 71, heated into drying gas in the drying module 70, and then sent out from the drying module 70 via the opening 72. In the present embodiment, the opening 72 is connected to the air outlet connecting portion 91 of the air outlet air duct 90 described below (see Figure 31 ).

[0159] And, as shown in Figure 28 , on the rear side of the drying module 70, there is also a recess 73, which corresponds to the part of the housing of the drying module 70 protruding forward, which is used to provide the main body portion of the air outlet air duct 90. The part opposite to the opening 72 of the drying module 70 is used to provide the air outlet connecting portion 91 of the air outlet air duct 90.

[0160] <Air inlet air duct>

[0161] The air inlet air duct 80 is used to guide the air in the laundry treatment drum (the first large drum 10, the first small drum 20, the second small drum 30, the second large drum 40) to the drying module 70. The perspective view of the air inlet air duct 80 is shown in Figure 29 and Figure 30 . As shown in Figure 32 , the air inlet air duct 80 is configured such that at least a portion of the air inlet air duct 80 extends from the rear side of at least any one of the first small drum 20 and the second small drum 30 in the lateral direction of the at least any one of the first small drum 20 and the second small drum 30 toward the front side. In this way, the setting space of the air duct can be saved to further achieve miniaturization. Here, the lateral direction of the small drum can be any one of the up-down-left-right directions of the small drum, or the oblique lateral direction of the small drum. Figure 29 is a perspective view of the air inlet air duct 80 observed from the front side (the opening side of the laundry treatment drum). As shown in Figure 29As shown, the air inlet duct 80 has a first air inlet portion 81 formed toward the upper side and opened upward in the upper portion, and a second air inlet portion 84 formed toward the lower side and opened toward the rear side in the lower portion. By forming the first air inlet portion 81 toward the upper side, the path from the first large drum 10 to the air inlet duct 80 can be made shorter, so that the air in the laundry treatment drum easily enters the drying assembly, reducing air resistance. By forming the second air inlet portion 84 toward the lower side, the path from the second large drum 40 to the air inlet duct 80 can be made shorter, so that the air in the laundry treatment drum easily enters the drying assembly, reducing air resistance. In the vertical direction, between the first air inlet portion 81 and the second air inlet portion 84, there is a main body portion that communicates with the first air inlet portion 81 and the second air inlet portion 84, and the main body portion has a curved portion 86 and a curved portion 87 at a position between the first small drum 20 and the second small drum 30, which are curved along part of the outer circumferential surface of the drum body of the first small drum 20 and the second small drum 30.

[0162] The air inlet duct 80 can make full use of the space between the first small drum 20 and the second small drum 30 for air guidance. The first small drum 20 and the second small drum 30 are cylindrical members, and the space between the two cylinders is wide at the upper part between the two small drums, and continuously narrows as it goes downward, becoming the narrowest at the line connecting the centers of the cylindrical shapes of the two small drums, and then continuously widens as it goes further downward, becoming wide at the lower part between the two small drums, about the same as the upper part between the two small drums.

[0163] The air inlet duct 80 has a shape that matches the cylindrical shape of the first small drum 20 and the second small drum 30, and can utilize the space between the two small drums as an air guidance channel.

[0164] Specifically, the air inlet duct 80 has a curved portion 86 on the side opposite the first small drum 20 in the left-right direction, and a curved portion 87 on the side opposite the second small drum 30 in the left-right direction, i.e., the air inlet duct 80 has a shape that matches the first small drum 20 and the second small drum 30 between the first small drum 20 and the second small drum 30, thereby partially surrounding the first small drum 20 and the second small drum 30. Through the curved portions 86 and 87, the space around the small drums can be further effectively utilized, and even the external space of the circular arc shape of the drum body periphery can be utilized as the space for the air duct.

[0165] As shown in FIG. 1, the air inlet duct 80 is formed in the space between the first small drum 20 and the second small drum 30, and has a first air inlet portion 81 formed toward the upper side and opened upward in the upper portion, and a second air inlet portion 84 formed toward the lower side and opened toward the rear side in the lower portion. Figure 29As shown, the curved portion 86 has a curvature radius that is approximately the same as the curvature radius of the cylindrical shape of the first small cylinder 20. The curved portion 86 extends downward along the outer circumference of the cylindrical shape of the first small cylinder 20 from a position approximately directly above 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°.

[0166] like Figure 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. The curved portion 87 extends downward 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, further surrounds the second small cylinder 30 and extends 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 case 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 within an angular range of, for example, 180° to 210°.

[0167] 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. Figure 29 In the embodiment, the main body portion where the bent portions 86 and 87 are formed has a shape in which a "T-shape of the upper left English letter" and a "reversed L-shape of the lower right English letter" are connected, for example.

[0168] exist Figure 30 FIG. 8 shows a three-dimensional view of the air inlet duct 80 from another perspective. Figure 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). Figure 30 As shown, the air inlet duct 80 has an air inlet connection portion 85 protruding and extending toward the rear side. 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. Thus, the air in the air inlet duct 80 can be guided into the drying module 70 through 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. Figure 30 As shown by the arrows at each air inlet portion.

[0169] In addition, if Figure 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. Figure 30 As shown, a triangular supporting 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 supporting member 88 is relatively thin, and it can appropriately exist in the space between the first small cylinder 20 and the second small cylinder 30. The supporting member 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, and increasing the cross-sectional area (the area perpendicular to the direction of gas flow) of the air inlet connection portion 85. In addition, since the thickness of the supporting 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 axis of rotation) of the first small cylinder 20 and the second small cylinder 30, thereby ensuring the overall air inlet area.

[0170] like Figure 29 、 Figure 30 As shown, the first air inlet portion 81 is, for example, a portion that protrudes upward from the main body and opens upward. The first air inlet portion 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 the illustration and description are omitted here. The second air inlet portion 84 is, for example, a portion that is located at the lower part of the main body and opens toward the rear from the main body. The second air inlet portion 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.

[0171] <Air outlet duct>

[0172] The air outlet duct 90 is used to send 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). Figure 31 , a perspective view of the air outlet duct 90 is shown as viewed from the front side. Figure 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 greater than its 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 through the air outlet connection portion 91. Since the air outlet connection portion 91 is configured in a manner such that its main surface direction faces the left-to-right direction, even if the drying module 70 occupies most of the space behind the first small cylinder 20 and the second small cylinder 30, the air outlet connection portion 91 can be configured to be aligned with the drying module 70 in the left-to-right direction. In this way, the space behind the first small cylinder 20 and the second small cylinder 30 can be further fully utilized.

[0173] Likewise Figure 31 As shown, the air outlet duct 90 also has a main body portion with the vertical direction as the longitudinal direction (i.e., the vertical dimension is the longest). The size of the main body portion in the front-to-back direction is smaller than the size in the left-to-right direction, and the size of the main body portion in the left-to-right direction is smaller than the size in the top-to-bottom direction. The reason for setting the size of the main body portion in the front-to-back direction to be smaller is that after the drying module 70 is set on the rear side of the first small cylinder 20 and the second small cylinder 30, the space remaining between the drying module 70 and the box assembly 1 is small. If the main body portion is larger in the front-to-back direction, the main body portion cannot be set in the recess 73 of the drying module 70. In addition, since the first large cylinder 10 and the second large cylinder 40 are larger in size, the space between the two large cylinders and the box assembly 1 is also small. Therefore, the front-to-back dimensions of the main body portion are also smaller in order to be set on the rear side of the first large cylinder 10 and the rear side of the second large cylinder 40. The main body portion has a first air outlet portion 92 formed upward and open to the front at the upper portion near the upper side, and a second air outlet portion 93 formed downward and open to the front at the lower portion near 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.

[0174] Combine Figure 26 and Figure 31 , the configuration position of the air outlet duct 90 is described, such as Figure 26As shown, the air outlet connecting portion 91 of the air outlet air duct 90 is arranged in the left-right direction in line with the drying module 70 and communicates with the drying module 70. The main body portion of the air outlet air duct 90 is formed at the rear side of the air outlet connecting portion 91 and the drying module 70, the portion of the main body portion in which the first air outlet portion 92 is formed extends upward to the rear side of the first large drum 10 and communicates with the first large drum 10, and the portion of the main body portion in which the second air outlet portion 93 is formed extends downward to the rear side of the second large drum 40 and communicates with the second large drum 40. In addition, as shown, the air outlet air duct 90 also has an opening 94 that communicates with the first small drum 20 and the second small drum 30, via which the air outlet air duct 90 communicates with the first small drum 20 and the second small drum 30, so as to send the gas heated in the drying module 70 to the first small drum 20 and the second small drum 30. Figure 31

[0175] As described above, by making the air outlet air duct 90 have the air outlet connecting portion 91 that is shorter in size in the left-right direction than in the front-rear direction and the up-down direction, the space at the rear side of the first small drum 20 and the second small drum 30 that is not occupied by the drying module 70 can be utilized, and by making the air outlet air duct 90 have the main body portion that is shorter in size in the front-rear direction than in the left-right direction and the up-down direction, the rear side space of the drying module 70 (the space at the recess 73), the rear side space of the first large drum 10, and the rear side space of the second large drum 40 can be utilized.

[0176] As described above, by making the air outlet connecting portion 91 communicate with the drying module 70, making the first air outlet portion 92 communicate with the first large drum 10, and making the second air outlet portion 93 communicate with the second large drum 40, the drying gas generated in the drying module 70 can be circulated and circulated.

[0177] Taking the drying of the clothes in the first large drum 10 as an example, the air inside the first large drum 10 is guided from the first large drum 10 to the air inlet air duct 80 via the first air inlet portion 81, and then guided to the drying module 70 via the opening 71 by the air inlet connecting portion 85, heated in the drying module 70 to generate drying gas, and then enters the air outlet air duct 90 via the opening 72 of the drying module 70 and the air outlet connecting portion 91 of the air outlet air duct 90, and then the drying gas circulates inside the air outlet air duct 90 to the first air outlet portion 92, and then enters the first large drum 10 via the first air outlet portion 92, thereby realizing the circulation of the gas between the first large drum 10, the air inlet air duct 80, the drying module 70, the air outlet air duct 90, and the first large drum 10. The same applies to the drying of the clothes in the first small drum 20, the second small drum 30, and the second large drum 40, and the circulation of the gas between the drying module 70 and the first small drum 20 (or the second small drum 30 and the second large drum 40) is realized via different air outlet portions.

[0178] <Effects based on the structure of the small drum periphery>​

[0179] In Figure 32 the cross-sectional view taken at the position between the first large drum 10 and the first small drum 20 and the second small drum 30 is shown. As Figure 32 indicated, 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 drum 20 and the second small drum 30, and the air inlet duct 80 also has a shape that cooperates with the first small drum 20 and the second small drum 30, and can pass through the narrow space between the first small drum 20 and the second small drum 30 to transmit the gas to the lower side of the space between the first small drum 20 and the second small drum 30, so that even the second large drum 40 located below can be transmitted with the drying gas.

[0180] As described above, since at least a part of the air inlet duct 80 is located between the first small drum 20 and the second small drum 30, the space between the two cylindrical shapes of the first small drum 20 and the second small drum 30 can be utilized, the drying gas can be delivered to multiple laundry treatment drums without occupying additional space to set the air inlet duct, the air supply duct setting space can be saved, the compactness of the configuration of each component in the multi-drum laundry treatment device is achieved, and miniaturization is achieved. Moreover, the drying module 70 is provided on any one of the rear side, the upper side, and the lower side of the first small drum 20 and the second small drum 30, and the drying module 70 is relatively close to each drum body, which corresponds to the structure of setting the air inlet duct 80 by utilizing the small drum peripheral space, not only achieving miniaturization, but also improving the drying effect, especially improving the drying effect for small drums, which is beneficial to using the drying module to provide drying gas for each laundry treatment drum, improves the utilization of space, and especially reduces the height of the multi-drum laundry treatment device when the drying module 70 is provided on the rear side of the first small drum 20 and the second small drum 30.

[0181] In addition, the multi-drum laundry treatment device 100 adopting the present application can fully utilize the space around the laundry treatment drum in the cabinet assembly 1, as Figure 32 indicated, the drying module 70 is provided on the rear side of the first small drum 20 and the second small drum 30, and the drying module 70 almost covers most of the space between the rear side of the first small drum 20 and the second small drum 30 and the cabinet assembly 1, so that the size of the drying module 70 can be fully ensured, and the drying module 70 can generate enough drying gas to meet the drying demand of multiple laundry treatment drums.

[0182] In addition, as Figure 32As shown, even if the drying module 70 is provided to be large enough, at least a part of the air outlet duct 90 (for example, the air outlet connecting portion 91) can be provided using the remaining part of the space between the rear side of the first and second small drums 20 and 30 and the cabinet assembly 1. Also, at least a part of the main body portion of the air outlet duct 90 can be provided at the recessed portion of the rear side of the drying module 70. Thus, in terms of the space where the first and second small drums 20 and 30 are located, the components can be arranged in a manner that there is almost no wasted space. This greatly achieves a compact structure, and further, miniaturization.

[0183] [Other structures and modifications of the present application]

[0184] (1) In the front view of the multi-drum laundry treating apparatus, the imaginary line connecting the centers of the circles of the first and second small drums 20 and 30 can be inclined at an angle of 0 to 15 degrees with respect to the horizontal plane, and more preferably, the imaginary line can be parallel to the horizontal plane.

[0185] (2) In the multi-drum laundry treating apparatus of the present application, the small drums are not limited to the first and second small drums 20 and 30, and can be more than two. In the case where there are more than two small drums, for example, the more than two small drums can be arranged in the left-right direction between the first and second large drums 10 and 40. By having the plurality of small drums, more laundry can be treated, and the arrangement of the two small drums in the left-right direction can suppress the overall size of the apparatus in the up-down direction. Also, the more than two small drums can be arranged in two layers between the first and second large drums 10 and 40. In this case, the small drums can be elastically supported by being compressed by the elastic damper, thereby suppressing vibration and achieving miniaturization. Also, the air inlet duct 80 can be provided in the peripheral space of any one of the small drums, and the use of the space around the small drums can further achieve miniaturization of the overall apparatus. For example, at least a part of the air inlet duct 80 can be provided between adjacent two of the more than two small drums in the left-right direction, or between one of the small drums adjacent to the cabinet assembly 1 and the cabinet assembly 1 in the left-right direction. Thus, the space between the two small drums in the peripheral structure of the small drums or the space between the small drums and the cabinet assembly can be effectively used to compactly provide the air inlet duct and the small drums without separately providing a space for the duct.

[0186] (3) The drying module 70 can be formed on the upper side or the lower side of the first and second small drums 20 and 30, in addition to being provided on the rear side of the first and second small drums 20 and 30. If the drying module 70 is provided on the upper side or the lower side, the depth of the first and second small drums 20 and 30 can be appropriately increased, and the capacity of the first and second small drums 20 and 30 can be increased. In this case, the air inlet duct 80 can also be provided using the space around the first and second small drums 20 and 30.

[0187] (4) For any of the intake air ducts 80, in addition to being able to be provided between the first small drum 20 and the second small drum 30, it is also possible to be provided to the side of the drum body of either of the first small drum 20 and the second small drum 30 in the left-right direction, i.e., between the first small drum 20 and the cabinet assembly 1 or between the second small drum 30 and the cabinet assembly 1.

[0188] (5) The intake air duct 80 can be connected to at least one of the first large drum 10, the first small drum 20, and the second small drum 30, the second large drum 40, and guide the air inside at least one of the first large drum 10, the first small drum 20, and the second small drum 30, the second large drum 40 into the drying module 70. The outlet air duct 90 can be connected to at least one of the first large drum 10, the first small drum 20, and the second small drum 30, the second large drum 40 corresponding to the intake air duct 80, and guide the air heated by the drying module 70 to at least one of the first large drum 10, the first small drum 20, and the second small drum 30, the second large drum 40.

[0189] (6) The outlet portion (first outlet portion 92, second outlet portion 93, other outlet portions not shown) of the outlet air duct is connected to at least one of the first large drum 10, the first small drum 20, the second small drum 30, the second large drum 40 from the rear, and the air in the outlet air duct 90 flows into at least one of the first large drum 10, the first small drum 20, the second small drum 30, the second large drum 40 via the outlet portion, thereby not only enabling the circulation of the drying gas between the laundry treatment drum and the drying module 70 based on the intake air duct 80 and the outlet air duct 90 to continuously dry the laundry, but also enabling the full use of the space behind the laundry treatment drum by connecting the outlet portion to the laundry treatment drum from the rear.

[0190] (7) The curved portions 86, 87 can have only one or both. In addition, the curved portions 86, 87 are not limited to being opposite the side surface in the left-right direction of the small drum, i.e., not limited to following the outer peripheral surface of the drum body of the small drum, but can also be opposite the side surface in the up-down direction of the small drum or opposite the diagonal side surface of the small drum.

[0191] (8) The orientation (opening direction) of the openings of the above-mentioned first intake portion 81, second intake portion 84 is not particularly limited as long as the circulation of the gas can be satisfied.

[0192] (9) A duct fan 95 for flowing air is provided in at least either of the intake air duct 80 and the outlet air duct 90, and by providing the duct fan 95 in at least either of the intake air duct 80 and the outlet air duct 90, the circulation of the drying gas in the duct can be facilitated. In Figure 32In the middle, the shell of the air outlet air duct 90 is omitted, so as to show the air duct fan 95 arranged in the air outlet air duct 90. For example, the air duct fan 95 for making air flow is arranged at the air outlet connecting part 91, and the air duct fan 95 is arranged at the side of the drying module 70 in the left-right direction, and the rotating axis of the air duct fan 95 extends along the left-right direction. By arranging the air duct fan 95 at the side of the drying module 70, not only can help the drying gas flow in the air duct, but also can effectively utilize the space at the side of the drying module 70, which is helpful for further miniaturization.

[0193] (10) The cooling fan 74 is arranged at the rear side of the drying module 70, and the cooling fan 74 can also be arranged at one of the left and right sides of the drying module 70.

[0194] (11) The multi-cylinder clothes treatment device 100 further comprises a switching part arranged in at least one of the air inlet air duct 80 and the air outlet air duct 90, for controlling the opening and closing and / or the air volume of the air duct. By having the switching part, the opening and closing and / or the air volume of the air duct can be controlled.

[0195] (12) The air duct is provided with a fragrance in at least one of the air inlet air duct 80 and the air outlet air duct 90, so that the gas for drying the clothes has a fragrance, which can be attached to the clothes, giving the user a better experience.

[0196] (13) The filter assembly is arranged in the air inlet duct 80, and the air introduced into the air inlet duct 80 is guided to the drying module 70 after being filtered by the filter assembly. The lint such as threads or fluff contained in the drying gas can be filtered by the filter assembly. In addition, the air inlet duct 80 is fixed to at least any one of the drying module 70, the cabinet assembly 1, and the two or more small cylinders. It should be noted that the air inlet duct 80 can be fixed to two or more small cylinders at the same time, or only one of them. By fixing the air inlet duct 80, the vibration that may occur when the drying gas flows in the air inlet duct 80 can be inhibited. By arranging the air inlet duct 80 between the two small cylinders and rigidly connecting the air inlet duct 80 with the two small cylinders, the two small cylinders can be fixed by the air inlet duct 80 to form a counterweight with each other to inhibit the vibration generated when the small cylinders rotate. In addition, when the number of small cylinders is more than two, a plurality of air inlet ducts 80 can be correspondingly provided. The plurality of air inlet ducts 80 can be respectively arranged between two adjacent small cylinders in the plurality of small cylinders, thereby also achieving the effect of inhibiting the vibration generated when the plurality of small cylinders rotate. The rigid connection manner is not limited, for example, a connection part can be additionally arranged at a non-air inlet connection position outside the shell of the air inlet duct 80. Preferably, at least any one of the first air inlet part 81 and the second air inlet part 84 (also including the air inlet part communicated with the small cylinder) is connected with the laundry treatment cavity of at least one of the first large cylinder 10, the two or more small cylinders (including but not limited to the first small cylinder 20 and the second small cylinder 30), and the second large cylinder 40 by elastic connection of the elastic buffer or rigid connection. The air inlet connection part 85 is connected with the drying module 70 by elastic connection of the elastic buffer or rigid connection. By elastic connection or rigid connection of the elastic buffer, the air inlet part (the first air inlet part 81, the second air inlet part 84, and the air inlet part communicated with the small cylinder) and the laundry treatment cavity are connected, and the air inlet connection part 85 and the drying module 70 are connected. The elastic buffer can be used to absorb the vibration that may occur at the connection site, further improve the effect of absorbing vibration, or in the case of a drying machine cylinder or when the air inlet part is not fixed to the laundry treatment cylinder that vibrates, the connection structure can be simplified by rigid connection. Similarly, for the air outlet duct 90, the air outlet part (the first air outlet part 92, the second air outlet part 93, and other air outlet parts not shown) can be connected with the laundry treatment cavity of at least one of the first large cylinder 10, the two or more small cylinders (including but not limited to the first small cylinder 20 and the second small cylinder 30), and the second large cylinder 40 by elastic connection of the elastic buffer or rigid connection, and the air outlet connection part 91 is connected with the drying module 70 by elastic connection of the elastic buffer or rigid connection.

[0197] In addition to saving the space for the air duct to achieve miniaturization, the space around the small drum can also be used to set up a drying module or a dropping function module to achieve miniaturization. In the multi-drum clothes treatment device, with the axis extending in the front-rear direction through the rotation center of the first large drum 10 as the center line, at least a part of the drying module or at least a part of the dropping function module is arranged on the side opposite to the small drum relative to the center line when viewed from the front.

[0198] In this way, not only the space around the small drum is utilized, but also the drying module arranged around the small drum is used as a counterweight to balance the center of gravity of the multi-drum clothes treatment device as a whole, to suppress the vibration of the multi-drum clothes treatment device when the clothes treatment drum (including the large drum and the small drum) rotates, while the arrangement can make the drying module relatively close to each drum, which is beneficial to shorten the drying airflow path and reduce the heat and air volume loss during the conveying of the drying airflow.

[0199] In the case of a heat pump type drying module, it is preferred that at least two of the compressor, the condenser, the evaporator, and the fan of the drying module are located on the side opposite to the small drum. It is also preferred that the compressor is located behind the small drum, and the condenser, the evaporator, and the fan are located on the side opposite to the small drum relative to the center line. Such structures can effectively utilize the space around the small drum while better balancing the center of gravity of the device.

[0200] In the case of an electric heating type drying module, it is preferred that at least one of the electric heater and the fan of the drying module is located on the side opposite to the small drum. Such structures can effectively utilize the space around the small drum while better balancing the center of gravity of the device.

[0201] For the case of setting the dispensing function module at the periphery of the small drum, the dispensing function module has at least one of a replaceable laundry treatment agent cartridge, a cavity pre-filled with laundry treatment agent, and a pump portion for automatically supplying laundry treatment agent. When viewed from the front, at least one of the replaceable laundry treatment agent cartridge, the cavity, and the pump portion is located on the side opposite to the small drum relative to the center line O. As with the case of setting the drying module, in the case of setting the dispensing function module, the space at the periphery of the small drum can also be utilized and the center of gravity of the device can be better balanced, thereby suppressing the vibration of the multi-drum laundry treatment device when the laundry treatment drum (including the large drum and the small drum) rotates. At the same time, the arrangement can make the dispensing function module relatively close to each drum, which is conducive to shortening the dispensing path, reducing the power requirement for dispensing, and reducing the residue and waste of the dispensing agent in the dispensing pipeline. Preferably, an opening portion for pre-filling the dispensing function module with laundry treatment agent or replacing the replaceable laundry treatment agent cartridge is provided at a position of the cabinet assembly that is located on the side of the door of the small drum. By having the opening portion at the position on the side of the door of the small drum, the laundry treatment agent can be easily filled or the laundry treatment agent cartridge can be easily replaced.

[0202] The above structure can make full use of the periphery of the small drum, improve the utilization rate of space, use at least part of the drying module and at least part of the dispensing function module as counterweights, thereby moving the center of gravity of the whole to the center side of the multi-drum laundry treatment device, and the vibration caused by the inner drum rotating for the small drum can be suppressed to a certain extent. Therefore, the special counterweight for the small drum can be cancelled or reduced. In addition, at least part of the drying module or at least part of the dispensing function module can also function as the counterweight of the large drum located above and / or below both, and the special counterweight for the large drum can be cancelled or reduced. Thus, it is conducive to realizing the miniaturization of the multi-drum laundry treatment device.

[0203] Since the drying module or the dispensing function module is arranged at the periphery of the small drum and below the first large drum 10 and above the second large drum 40, the distance from the drying module or the dispensing function module to each laundry treatment drum can be shortened, and the drying efficiency of the drying module or the dispensing efficiency of the dispensing function module can be improved.

[0204] The structures described above can be used in combination with each other without conflict, for example, even if the air inlet duct 80 is arranged between the first small drum 20 and the second small drum 30 to save space for the air supply duct (see Figure 24 ), the connecting plate 58 (see Figure 23), the air inlet duct 80 is arranged in the space between the first small cylinder 20 and the second small cylinder 30, and does not completely occupy the space between the first small cylinder 20 and the second small cylinder 30, so that the connecting plate 58 can still be arranged to connect the first small cylinder 20 and the second small cylinder 30 into one body. Those skilled in the art can arbitrarily combine various constituent elements in the technical solutions of the present application under the premise that each structure does not conflict.
