[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following description, with reference to the accompanying drawings, describes a tubular assembly 100 of a garment handling device according to an embodiment of the present invention. Figures 1-9 As shown, the tubular assembly 100 of the garment processing device according to an embodiment of the present invention includes an outer tubing 1, an inner tubing, a first cleaning tube 2, and a second cleaning tube 3.

[0030] The outer cylinder 1 includes a connected outer cylinder portion 11 and an outer cylinder bottom cover 12. An inner cylinder is disposed inside the outer cylinder 1, and includes a connected inner cylinder portion and an inner cylinder bottom cover 200. A first cleaning pipe 2 extends circumferentially along the outer cylinder 1, and is located between the inner cylinder bottom cover 200 and the outer cylinder bottom cover 12 in the longitudinal direction of the outer cylinder 1, so that the first cleaning pipe 2 can be positioned behind the inner cylinder bottom cover 200 of the inner cylinder, thereby enabling cleaning of the inner cylinder bottom cover 200. A second cleaning pipe 3 extends along the longitudinal direction of the outer cylinder 1, and is located radially between the outer cylinder 1 and the inner cylinder.

[0031] When the inner drum of the garment cleaning device needs to be cleaned, it can be rotated. The cleaning water sprayed from the first cleaning pipe 2 cleans the bottom cover 200 of the inner drum, while the cleaning water sprayed from the second cleaning pipe 3 cleans the inner drum itself. This effectively removes dirt, fibers, bacteria, mold, and scale remaining on the inner drum, thereby improving the washing effect of the garment cleaning device and enhancing the cleanliness and hygiene of the clothes.

[0032] Moreover, the inner drum assembly 100 of the garment processing device according to the present invention only needs to be provided with two cleaning pipes to effectively clean the entire inner drum, which has the advantage of simple structure.

[0033] Therefore, the drum assembly 100 of the garment processing device according to the present utility model has the advantages of effectively cleaning the inner drum, improving the washing effect of the garment processing device, and having a simple structure.

[0034] The garment processing device according to an embodiment of the present invention includes a drum assembly 100. Therefore, the garment processing device according to an embodiment of the present invention has advantages such as high inner drum cleanliness, good washing effect, and simple structure, and can effectively clean garments.

[0035] To make the technical solution of this application easier to understand, the following description uses the example of the length direction (axial direction of the outer cylinder 1) being consistent with the front-to-back direction of the outer cylinder 1. The front-to-back direction is as follows... Figure 4 As shown by arrow A in the diagram.

[0036] The inner cylinder includes an inner cylinder portion and an inner cylinder bottom cover 200, the inner cylinder bottom cover 200 being connected to the rear edge of the inner cylinder portion. The outer cylinder 1 includes an outer cylinder portion 11 and an outer cylinder bottom cover 12, the outer cylinder portion 11 including a rear cylinder 111 and a front cylinder 112. The rear cylinder 111 and the front cylinder 112 are arranged along the length direction of the outer cylinder 1, with the rear cylinder 111 located behind the front cylinder 112. The outer cylinder bottom cover 12 is connected to the rear edge of the rear cylinder 111. Optionally, the outer cylinder bottom cover 12 and the rear cylinder 111 are integrally formed to reduce the manufacturing difficulty and cost of the outer cylinder 1.

[0037] The first cleaning pipe 2 is disposed inside the outer cylinder 1. The first cleaning pipe 2 is located along the length of the outer cylinder 1 between the outer cylinder bottom cover 12 and the inner cylinder bottom cover 200, i.e., behind the inner cylinder bottom cover 200, so that the first cleaning pipe 2 can clean the inner cylinder bottom cover 200. Specifically, the first cleaning pipe 2 is disposed in at least one of the rear cylinder 111 and the outer cylinder bottom cover 12.

[0038] like Figure 1 , Figure 2 and Figure 4As shown, the first cleaning pipe 2 is located at the connection between the rear drum 111 and the outer drum bottom cover 12. Therefore, the first cleaning pipe 2 can not only clean the inner drum bottom cover 200, but also the connection between the inner drum and the inner drum bottom cover 200, thus avoiding cleaning dead spots and more effectively cleaning the inner drum. This allows for a more thorough removal of dirt, fibers, bacteria, mold, and scale remaining on the inner drum, further improving the washing effect of the garment treatment device.

[0039] like Figure 4 and Figure 5 As shown, at least one of the rear cylinder 111 and the outer cylinder bottom cover 12 is provided with a first receiving groove, and the first cleaning pipe 2 is fitted into the first receiving groove. By fitting the first cleaning pipe 2 into the first receiving groove, the space occupied by the first cleaning pipe 2 can be reduced. This avoids the first cleaning pipe 2 interfering with the inner cylinder, and the volume of the inner cylinder will not be reduced due to the first cleaning pipe 2 being installed in the outer cylinder 1 of the cylinder assembly 100.

[0040] Optionally, the first portion 21 of the first cleaning tube 2 protrudes from the inner surface of at least one of the rear cylinder 111 and the outer cylinder bottom cover 12. The second portion 25 of the first cleaning tube 2 fits into the first receiving groove, that is, the second portion 25 of the first cleaning tube 2 is embedded in at least one of the rear cylinder 111 and the outer cylinder bottom cover 12.

[0041] By embedding a portion (second portion 25) of the first cleaning tube 2 into at least one of the rear cylinder 111 and the outer cylinder bottom cover 12, the space occupied by the protruding portion (first portion 21) of the first cleaning tube 2 can be reduced. This not only avoids the first cleaning tube 2 interfering with the inner cylinder and prevents the volume of the inner cylinder from being reduced due to the placement of the first cleaning tube 2 inside the outer cylinder 1 of the cylinder assembly 100, but also facilitates the cleaning of the inner cylinder bottom cover 200 by the first cleaning tube 2.

[0042] For example, the second part 25 of the first cleaning tube 2 is embedded in the connection between the rear cylinder 111 and the outer cylinder bottom cover 12, that is, the second part 25 of the first cleaning tube 2 is embedded in the rear cylinder 111 and the outer cylinder bottom cover 12. The first part 21 of the first cleaning tube 2 protrudes from the inner surface 1111 of the rear cylinder 111 and the inner surface 121 of the outer cylinder bottom cover 12.

[0043] Optionally, the rear cylinder 111, the outer cylinder bottom cover 12, and the first cleaning pipe 2 are integrally formed. This not only reduces the manufacturing difficulty and cost of the cylinder assembly 100, but also eliminates the need for additional installation of the first cleaning pipe 2, thereby reducing the assembly difficulty of the cylinder assembly 100 and improving the assembly efficiency of the cylinder assembly 100.

[0044] The first cleaning pipe 2 extends circumferentially along the outer cylinder 1. Optionally, the first cleaning pipe 2 is annular so that the first cleaning pipe 2 can more fully and effectively clean the inner cylinder bottom cover 200 of the inner cylinder, thereby more thoroughly removing dirt, fibers, bacteria, mold and scale remaining on the inner cylinder bottom cover 200 of the inner cylinder.

[0045] like Figure 6 and Figure 7 As shown, the first part 21 of the first cleaning pipe 2 is provided with a plurality of first cleaning holes, which are spaced apart along the circumference of the outer cylinder 1. Thus, the first cleaning pipe 2 can more fully and effectively clean the inner cylinder bottom cover 200 of the inner cylinder, thereby more thoroughly removing dirt, fibers, bacteria, mold and scale remaining on the inner cylinder bottom cover 200 of the inner cylinder.

[0046] Optionally, the outlets of the multiple first cleaning holes open in different directions. As a result, the first cleaning pipe 2 can more fully and comprehensively clean the inner cylinder bottom cover 200, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200.

[0047] like Figure 6 and Figure 7 As shown, the plurality of first cleaning holes include at least two of an inner cleaning hole 23, an outer cleaning hole 22, and a middle cleaning hole 24. The outlet of the inner cleaning hole 23 opens toward the center of the inner cylinder bottom cover 200, the outlet of the outer cleaning hole 22 opens toward the edge of the inner cylinder bottom cover 200, and the middle cleaning hole 24 opens toward the portion between the center and the edge of the inner cylinder bottom cover 200. Thus, the first cleaning pipe 2 can more fully and comprehensively clean the inner cylinder bottom cover 200, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200.

[0048] like Figure 6 and Figure 7 As shown, the plurality of first cleaning holes include at least one outer cleaning hole 22 and at least one inner cleaning hole 23, with the outer cleaning hole 22 located radially outside the inner cleaning hole 23 of the outer cylinder 1. The outer surface 201 of the inner cylinder bottom cover 200 includes a middle portion 202 and an outer portion 203, with the outer portion 203 located radially outside the middle portion 202 of the inner cylinder bottom cover 200 (radial direction of the outer cylinder 1). The radial direction of the outer cylinder 1 is as follows: Figure 6 and Figure 8 As shown by arrow B in the diagram.

[0049] The outlet of the inner cleaning hole 23 is opposite to the middle 202 of the outer surface 201 of the inner cylinder bottom cover 200. The cleaning water sprayed from the inner cleaning hole 23 can clean the middle 202 of the outer surface 201 of the inner cylinder bottom cover 200. The outlet of the outer cleaning hole 22 is opposite to the outer side 203 of the outer surface 201 of the inner cylinder bottom cover 200. The cleaning water sprayed from the outer cleaning hole 22 can clean the outer side 203 of the outer surface 201 of the inner cylinder bottom cover 200. Thus, the first cleaning pipe 2 can more fully and comprehensively clean the inner cylinder bottom cover 200 of the inner cylinder, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200 of the inner cylinder.

[0050] like Figure 6 and Figure 7 As shown, the plurality of first cleaning holes also include at least one intermediate cleaning hole 24, which is located radially between the outer cleaning hole 22 and the inner cleaning hole 23 of the outer cylinder 1. The outer surface 201 of the inner cylinder bottom cover 200 also includes a transition portion 204, which is located between the middle portion 202 and the outer portion 203 in the inward and outward directions of the inner cylinder bottom cover 200.

[0051] The outlet of the intermediate cleaning hole 24 is opposite to the transition portion 204 of the outer surface 201 of the inner cylinder bottom cover 200. The cleaning water sprayed from the intermediate cleaning hole 24 can clean the transition portion 204 of the outer surface 201 of the inner cylinder bottom cover 200. As a result, the first cleaning pipe 2 can more fully and comprehensively clean the inner cylinder bottom cover 200, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200.

[0052] like Figure 7 As shown, the outer cleaning hole 22, the intermediate cleaning hole 24, and the inner cleaning hole 23 are alternately arranged in the circumferential direction of the outer cylinder 1. That is, the outer cleaning hole 22, the intermediate cleaning hole 24, and the inner cleaning hole 23 are alternately arranged in the extension direction of the first cleaning pipe 2. The extension direction of the first cleaning pipe 2 is consistent with the circumferential direction of the outer cylinder 1. This makes the structure of the first cleaning pipe 2 more reasonable, and allows the first cleaning pipe 2 to clean the inner cylinder bottom cover 200 of the inner cylinder more fully and comprehensively, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200 of the inner cylinder.

[0053] Optionally, the intermediate cleaning hole 24 is located circumferentially between the outer cleaning hole 22 and the inner cleaning hole 23 in the cross-section of the flow path of the first cleaning pipe 2. The outer cleaning hole 22 is adjacent to the rear cylinder 111 relative to the intermediate cleaning hole 24 in the cross-section of the flow path of the first cleaning pipe 2 in the circumferential direction, and the inner cleaning hole 23 is adjacent to the outer cylinder bottom cover 12 relative to the intermediate cleaning hole 24 in the circumferential direction of the cross-section of the flow path of the first cleaning pipe 2 in the circumferential direction. This allows the first cleaning pipe 2 to more fully and comprehensively clean the inner cylinder bottom cover 200, thereby more thoroughly removing dirt, fibers, bacteria, mold, and scale remaining on the inner cylinder bottom cover 200.

[0054] The flow path of the first cleaning pipe 2 refers to the flow path of water within the first cleaning pipe 2. For example, the first cleaning pipe 2 can be a circular pipe with a circumferential direction, and the circumferential direction of the cross-section of the flow path of the first cleaning pipe 2 is consistent with the circumferential direction of the first cleaning pipe 2.

[0055] The second cleaning pipe 3 is located inside the outer cylinder 1 and extends along the length of the outer cylinder 1. The second cleaning pipe 3 is located radially between the outer cylinder 1 and the inner cylinder. When it is necessary to clean the inner cylinder of the garment handling device, the inner cylinder can be rotated so that the second cleaning pipe 3 can clean the entire outer surface of the inner cylinder portion.

[0056] like Figures 1-4 As shown, the second cleaning pipe 3 is connected to the first cleaning pipe 2. Therefore, only one water outlet is needed to supply cleaning water to both the first cleaning pipe 2 and the second cleaning pipe 3, thus simplifying the structure of the garment processing device.

[0057] Specifically, the garment handling device may include a three-way water valve with one inlet and three outlets. The inlet of the water valve is connected to a municipal water source, one outlet of the water valve is connected to a dispensing box to supply water to the dispensing box, another outlet of the water valve is connected to the inlet of the outer drum portion 11 of the drum assembly 100 to deliver washing water into the outer drum portion 11, and a third outlet of the water valve is connected to at least one of the first cleaning pipe 2 and the second cleaning pipe 3 to supply cleaning water for cleaning the inner drum to the first cleaning pipe 2 and the second cleaning pipe 3.

[0058] For example, another outlet of the water valve is connected to the connection point of the first cleaning pipe 2 and the second cleaning pipe 3, so that another outlet of the water valve is connected to both the first cleaning pipe 2 and the second cleaning pipe 3.

[0059] Optionally, the rear cylinder 111, the outer cylinder bottom cover 12, the first cleaning pipe 2, and the second cleaning pipe 3 are integrally formed. This not only reduces the manufacturing difficulty and cost of the cylinder assembly 100, but also eliminates the need for additional installation of the first cleaning pipe 2 and the second cleaning pipe 3, thereby reducing the assembly difficulty and improving the assembly efficiency of the cylinder assembly 100. Specifically, when assembling the cylinder assembly 100, it is only necessary to connect the rear cylinder 111 and the front cylinder 112 together.

[0060] Alternatively, the wall of the first receiving tank forms part of the first cleaning pipe 2, and the wall of the second receiving tank forms part of the second cleaning pipe 3. This makes the structure of the cylinder assembly 100 more reasonable.

[0061] Optionally, the second cleaning pipe 3 is provided with a plurality of second cleaning holes 33, which are spaced apart along the length direction of the second cleaning pipe 3 (the length direction of the outer cylinder 1).

[0062] The rear cylinder 111 is provided with a second receiving groove, which extends along the length of the outer cylinder 1. The first section 31 of the second cleaning pipe 3 is radially opposite to the rear cylinder 111 of the outer cylinder 1, and the first section 31 of the second cleaning pipe 3 fits into the second receiving groove. By fitting the second cleaning pipe 3 into the second receiving groove, the space occupied by the second cleaning pipe 3 can be reduced. This avoids the second cleaning pipe 3 interfering with the inner cylinder, and the volume of the inner cylinder is not reduced due to the installation of the second cleaning pipe 3 in the outer cylinder 1.

[0063] like Figure 1 , Figure 2 and Figure 4 As shown, a portion of the first section 31 of the second cleaning tube 3 fits into the second receiving groove, that is, a portion of the first section 31 of the second cleaning tube 3 is embedded in the rear cylinder 111. This allows another portion of the first section 31 of the second cleaning tube 3 to protrude from the rear cylinder 111, thereby facilitating the cleaning of the inner cylinder portion of the inner cylinder by the second cleaning tube 3.

[0064] like Figure 1 , Figure 8 and Figure 9 As shown, the inner surface 1121 of the front cylinder 112 is provided with a third receiving groove 114, which extends along the length of the outer cylinder 1. The second section 32 of the second cleaning tube 3 is opposite to the front cylinder 112 in the radial direction of the outer cylinder 1, and the second section 32 of the second cleaning tube 3 is fitted into the third receiving groove 114.

[0065] By fitting the second section 32 of the second cleaning pipe 3 into the third receiving groove 114, the space occupied by the second section 32 of the second cleaning pipe 3 can be reduced. This avoids the second cleaning pipe 3 interfering with the inner cylinder, and the volume of the inner cylinder will not be reduced due to the installation of the second cleaning pipe 3 in the outer cylinder 1 of the cylinder assembly 100.

[0066] Optionally, a portion of the second section 32 of the second cleaning pipe 3 is fitted into the third receiving groove 114, that is, a portion of the second section 32 of the second cleaning pipe 3 is embedded in the front cylinder 112. This allows another portion of the second section 32 of the second cleaning pipe 3 to protrude from the front cylinder 112, facilitating the cleaning of the inner cylinder portion of the inner cylinder by the second cleaning pipe 3.

[0067] like Figure 8 and Figure 9 As shown, the tubular assembly 100 of the garment processing device also includes a limiting member 4, which is disposed in the front tubular 112. The second segment 32 of the second cleaning tube 3 is clamped between the limiting member 4 and the wall of the third receiving groove 114. That is, the limiting member 4 is located inside the front tubular 112. Thus, the limiting member 4 can be used to limit the second segment 32 (second cleaning tube 3), so that when the second cleaning tube 3 sprays cleaning water, the limiting member 4 can prevent the second segment 32 (second cleaning tube 3) from moving, so as to make the second cleaning tube 3 more stable.

[0068] Optionally, the limiting member 4 and the front cylinder 112 are integrally formed to reduce the manufacturing difficulty and cost of the front cylinder 112 (outer cylinder 1).

[0069] like Figure 8 and Figure 9 As shown, the limiting member 4 can be arc-shaped so that the shape of the limiting member 4 can better match the shape of the second segment 32 of the second cleaning tube 3, thereby clamping the second segment 32 of the second cleaning tube 3 more securely. There are multiple limiting members 4, which are spaced apart along the length direction of the second segment 32 of the second cleaning tube 3 (the length direction of the outer cylinder 1), so that the limiting members 4 clamp the second segment 32 of the second cleaning tube 3 more securely.
