[0052] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the embodiments of the present application, but the embodiments of the present application can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present application, and not all the embodiments.

[0053] Reference Figures 1 to 12 As shown in the figure, the present embodiment provides a clothes treatment device, which comprises a cabinet 1 and a clothes treatment drum 2 located in the cabinet 1.

[0054] A fan 3 is arranged in the cabinet 1, and the fan 3 is located outside the clothes treatment drum 2. The fan 3 comprises a volute 31 and an impeller 33 located in the volute 31. The outer side of the volute 31 is covered with an outer cover 4, and the fan 3 is connected with the cabinet 1 through the outer cover 4.

[0055] The outer cover 4 is provided with an air inlet 41 and an air outlet 42. The air inlet 41 is in communication with the outside, and the air outlet 42 is in communication with the air inlet 41 and the inner cavity of the clothes treatment drum 2, respectively, so that the outside air enters the inner cavity of the clothes treatment drum 2 through the air inlet 41 and the air outlet 42 under the action of the fan 3. Here, the outside specifically refers to the environment outside the clothes treatment drum 2 (such as the environment outside the cabinet or the environment inside the cabinet but outside the clothes treatment drum), and the outside air can enter the outer cover 4 through the air inlet 41 and then enter the clothes treatment drum 2.

[0056] In specific implementation, the clothes treatment device is a washing machine, which can be a drum washing machine or a pulsator washing machine.

[0057] When the clothes in the clothes treatment drum 2 are not taken out in time for airing after washing, the air outside the clothes treatment drum 2 can be transported into the inner cavity of the clothes treatment drum 2 through the air inlet 41 and the air outlet 42 of the outer cover 4 by the fan 3, so as to dry the inner cavity of the clothes treatment drum 2, avoid the formation of a dark and humid environment due to the residual moisture in the inner cavity of the clothes treatment drum 2, and thus avoid the generation of odor or bacteria on the clothes in the clothes treatment drum 2, thereby causing harm to the human body.

[0058] In a specific implementation, the fan 3 can be connected with the outer cover 4 first, and then the outer cover 4 is connected to the cabinet 1, that is, the fan 3 and the outer cover 4 can be modularly connected first, and then the whole is connected with the cabinet 1, which is convenient and fast to assemble. In addition, since the fan 3 is connected to the cabinet 1 through the outer cover 4, rather than being connected to the laundry treatment drum 2, the fan 3 can be prevented from loosening due to the vibration of the laundry treatment drum 2 to a certain extent, and the stability of the fan 3 is improved.

[0059] In summary, the laundry treatment device provided in the embodiment is provided with the fan 3 in the cabinet 1, the fan 3 is located outside the laundry treatment drum 2, the fan 3 includes the volute 31 and the impeller 33 located in the volute 31, the outer cover 4 is provided outside the volute 31, the fan 3 is connected with the cabinet 1 through the outer cover 4, the air inlet 41 and the air outlet 42 are formed on the outer cover 4, the air inlet 41 is communicated with the outside, and the air outlet 42 is respectively communicated with the air inlet 41 and the inner cavity of the laundry treatment drum 2, so that the outside air can enter the laundry treatment drum 2 through the air inlet 41 and the air outlet 42 under the action of the fan 3 to dry the laundry treatment drum 2, so as to avoid the formation of a dark and humid environment in the laundry treatment drum 2, and further cause odor or bacteria breeding, which can harm the human body. By covering the outer cover 4 outside the fan 3, the fan 3 can be easily installed on the cabinet 1, so that the installation structure on the volute of the fan is not needed to realize the installation of the fan, so that the selection space of the fan is larger, and the compatibility of the fan is improved. Moreover, the air outlet 42 is formed on the outer cover 4 to facilitate the connection of the outer cover 4 with the laundry treatment drum 2, so that the outside air can enter the laundry treatment drum 2 through the air outlet 42 under the action of the fan 3. In addition, since the fan 3 is connected to the cabinet 1 through the outer cover 4, rather than being connected to the laundry treatment drum 2, the fan 3 can be prevented from loosening due to the vibration of the laundry treatment drum 2 to a certain extent, and the stability of the fan 3 is improved.

[0060] Referring to Figures 1 to 12 In some embodiments, the cabinet 1 is provided with the connecting frame 7, the connecting frame 7 is located between the laundry treatment drum 2 and the inner wall of the cabinet 1, and the outer cover 4 is connected with the connecting frame 7.

[0061] That is, the outer cover 4 is connected with the connecting frame 7 on the cabinet 1, which facilitates the connection and assembly of the outer cover 4 on the cabinet 1.

[0062] In a specific implementation, the connecting frame 7 is a structure provided on the cabinet 1, such as a control panel for fixing the laundry treatment device. In addition, connecting the outer cover 4 to the connecting frame 7 can also avoid the situation that the outer cover 4 is directly connected to the laundry treatment drum 2, and the outer cover 4 is affected by vibration when the laundry treatment drum 2 is washed, resulting in vibration falling or vibration wear.

[0063] Exemplarily, the connecting frame 7 can be connected with the box body 1 by screws or bolts, or the connecting frame 7 can be snap-connected or welded with the box body 1 to ensure the connection reliability between the connecting frame 7 and the box body 1.

[0064] In some embodiments, the connecting frame 7 is located above the laundry treatment drum 2, so that the space above the laundry treatment drum 2 can be reasonably utilized to arrange the connecting frame 7, thereby improving the space utilization.

[0065] Referring to Figures 1 to 12 In some embodiments, the connecting mode between the outer cover 4 and the connecting frame 7 can be that the outer cover 4 is provided with a first clamping portion 43, the connecting frame 7 is provided with a second clamping portion 71 corresponding to the first clamping portion 43, and the outer cover 4 is snap-connected with the connecting frame 7 through the cooperation of the first clamping portion 43 and the second clamping portion 71. By providing the first clamping portion 43 on the outer cover 4 and the second clamping portion 71 on the connecting frame 7, the outer cover 4 can be snap-connected on the connecting frame 7 through the cooperation of the first clamping portion 43 and the second clamping portion 71, thereby realizing the reliable connection assembly of the two.

[0066] Exemplarily, one of the first clamping portion 43 and the second clamping portion 71 can be a clamping hole, and the other one of the first clamping portion 43 and the second clamping portion 71 can be a clamping buckle. For example, the clamping hole is arranged on the connecting frame 7, and the clamping buckle is arranged on the outer cover 4, and the clamping buckle is snap-connected in the clamping hole, thereby realizing the reliable connection of the outer cover 4 and the connecting frame 7. For another example, the clamping buckle is arranged on the connecting frame 7, and the clamping hole is arranged on the outer cover 4, and the clamping buckle is snap-connected in the clamping hole, thereby realizing the reliable connection of the outer cover 4 and the connecting frame 7.

[0067] Referring to Figures 2 to 7 In some embodiments, the first clamping portion 43 is at least two, and the at least two first clamping portions 43 are arranged at intervals on the outer cover 4; the second clamping portion 71 is at least two, and the at least two second clamping portions 71 are arranged at intervals on the connecting frame 7, and the second clamping portions 71 are arranged one by one corresponding to the first clamping portions 43.

[0068] That is, by arranging the first clamping portion 43 to be at least two, the at least two first clamping portions 43 are arranged at intervals on the outer cover 4, and the second clamping portion 71 is at least two to correspond one by one to the first clamping portion 43, thereby realizing snap-connection from multiple positions to further improve the connection stability of the outer cover 4 and the connecting frame 7, and prevent the two from being disconnected, thereby affecting the normal use of the laundry treatment equipment.

[0069] Exemplarily, referring to Figure 2As shown, the first engaging portion 43 can be two, and the second engaging portion 71 is also correspondingly provided with two, through the corresponding cooperation of the two first engaging portions 43 and the two second engaging portions 71, the reliable connection of the outer cover 4 and the connecting frame 7 is realized. Exemplarily, in other implementation manners, the first engaging portion 43 can be provided with three or more than three, and the number of the second engaging portion 71 is the same as that of the first engaging portion 43.

[0070] Referring to Figures 6 to 12 As shown, one side of the outer cover 4 has an opening 46 for the fan 3 to enter the outer cover 4, in some embodiments, the opening 46 can serve as the air inlet of the outer cover 4. The outer cover 4 includes a fan placement area 49, and the outer cover 4 is provided with a clamping portion 44 clamped on the outer surface of the volute 31 to fix the fan 3 in the fan placement area 49.

[0071] By providing the opening 46 on one side of the outer cover 4 for the fan 3 to enter, when assembling, the fan 3 is placed into the fan placement area 49 in the outer cover 4 through the opening 46 of the outer cover 4, and then the clamping portion 44 on the outer cover 4 is clamped on the outer surface of the volute 31, so that the fan 3 is clamped in the outer cover 4, which is convenient to assemble and reliable to connect.

[0072] Exemplarily, the clamping portion 44 can be a hook, which is hooked on the volute 31 of the fan 3, so as to realize the reliable connection of the fan 3 on the outer cover 4. Exemplarily, the hook can directly abut against the volute 31 of the fan 3 to fix the fan 3 in the volute. Alternatively, a clamping groove can also be formed on the volute 31 of the fan 3 corresponding to the hook, and the hook is hooked in the clamping groove, which can further improve the connection reliability of the fan 3 and the outer cover 4.

[0073] Exemplarily, the clamping portion 44 can also be a buckle or any other clamping structure that can fix the fan 3 on the outer cover 4.

[0074] Further, the clamping portion 44 is at least two, and the at least two clamping portions 44 are arranged along the circumference of the outer edge of the opening 46. By providing at least two clamping portions 44, the at least two clamping portions 44 are arranged along the circumference of the outer edge of the opening 46, so as to clamp the fan 3 from multiple positions, further improving the connection stability between the outer cover 4 and the fan 3.

[0075] Of course, in other implementation manners, the outer cover 4 and the fan 3 can also be detachably connected through threads or the like.

[0076] Referring to Figures 5 to 12 As shown, in some embodiments, the cover wall of the outer cover 4 opposite to the opening 46 is provided with an air inlet 41, and the air inlet 41 is a grid-shaped air inlet.

[0077] In a specific implementation, the air inlet 41 on the outer cover 4 is set as a grid-shaped air inlet, so that dust or foreign matter can be blocked by the grid-shaped structure, so as to reduce the entry of dust or foreign matter outside the outer cover 4 into the outer cover 4 through the air inlet 41, thereby playing a role in dustproof and foreign matter protection of the fan 3.

[0078] For example, when the opening 46 is arranged below the outer cover 4, the top wall of the outer cover 4 is arranged opposite to the opening 46, and the air inlet 41 can be arranged on the top wall of the outer cover 4.

[0079] For example, a plurality of air inlets 41 can be arranged on the outer cover 4, so that air can be inhaled through the plurality of air inlets 41 at the same time, so as to improve the air inhaul amount and further improve the air exchange efficiency in the clothes treatment drum 2.

[0080] Referring to Figures 1 to 12 As shown in the figure, in some embodiments, the side shell wall of the volute 31 facing the air inlet 41 and the side shell wall of the volute 31 facing the opening 46 are both provided with an air inlet 32 communicating with the inner cavity of the volute 31.

[0081] That is, by arranging the air inlet 41 on the cover wall of the outer cover 4 opposite to the opening 46, and arranging the air inlets 32 on the side shell wall of the volute 31 facing the air inlet 41 and the side shell wall of the volute 31 facing the opening 46, air can be inhaled through the air inlets 32 on the different side shell walls of the volute 31, so as to improve the air inhaul amount and further improve the air exchange efficiency in the clothes treatment drum 2, so as to further avoid the generation of odor or breeding of bacteria in the clothes treatment drum 2, and harm to the human body.

[0082] For example, when the opening 46 is arranged below the outer cover 4, the upper side shell wall of the volute 31 and the lower side shell wall of the volute 31 both have air inlets 32, and the air inlet 32 on the upper side shell wall of the volute 31 is arranged corresponding to the air inlet 41 on the top surface of the outer cover 4, so that the external air can enter the fan 3 through the air inlet 41 and the air inlet 32 on the upper side shell wall of the volute 31, or directly enter the fan 3 through the air inlet 32 on the lower side shell wall of the volute 31, so as to realize air inhaul through the air inlets 32 on the different side shell walls of the volute 31, improve the air inhaul amount, and further improve the air exchange efficiency in the clothes treatment drum 2, so as to further avoid the generation of odor or breeding of bacteria in the clothes treatment drum 2, and harm to the human body.

[0083] Referring to Figures 1 to 12As shown, in some embodiments, the side shell wall of the volute 31 facing the air inlet 41 is located above the side shell wall of the volute 31 facing the opening 46. In this case, the total area of the air inlets 32 on the side shell wall of the volute 31 facing the opening 46 is not less than the total area of the air inlets 32 on the side shell wall of the volute 31 facing the air inlet 41.

[0084] For example, the opening 46 is arranged at the lower part of the outer cover 4, in which case the side shell wall of the volute 31 facing the opening 46 is the lower side shell wall of the volute 31, the side shell wall of the volute 31 facing the air inlet 41 is the upper side shell wall of the volute 31, and the upper side shell wall is located above the lower side shell wall. In this case, the total area of the air inlets 32 on the upper side shell wall is less than the total area of the air inlets 32 on the lower side shell wall, while ensuring that air can be drawn in through the air inlets 32 on the upper side shell wall and the air inlets 32 on the lower side shell wall at the same time. This can further increase the air volume and ensure the drying effect, and the area of the air inlets on the side of the volute facing the opening 46 can be set to be relatively large. Since this side faces downward, the occurrence of the situation that dust or foreign matter enters the fan 3 through the air inlets 32 of the volute 31 and affects the fan 3 can be reduced to a certain extent.

[0085] Referring to Figures 1 to 12 As shown, in some embodiments, the outer cover 4 has an air outlet duct 45, which is in communication with the air outlet 42 and the inner cavity of the clothes treatment drum 2, respectively, and at least part of the structure of the air outlet duct 45 extends toward the clothes treatment drum 2.

[0086] By arranging the outer cover 4 to have the air outlet duct 45, the air outlet 42 and the inner cavity of the clothes treatment drum 2 can be communicated through the air outlet duct 45, which facilitates the communication between the air outlet 42 and the inner cavity of the clothes treatment drum 2 and the connection between the outer cover 4 and the clothes treatment drum 2 through the air outlet duct 45. At least part of the structure of the air outlet duct 45 extends toward the clothes treatment drum 2, thereby facilitating the connection assembly between the outer cover 4 and the clothes treatment drum 2.

[0087] For example, the outer cover 4 is arranged above the clothes treatment drum 2, in which case the air outlet duct 45 can extend substantially along the radial direction of the clothes treatment drum 2 as a whole, thereby facilitating the connection between the outer cover 4 and the clothes treatment drum 2.

[0088] In some embodiments, the air outlet duct 45 is integrally formed with the outer cover 4. By arranging the air outlet duct 45 to be integrally formed with the outer cover 4, the manufacturing process can be saved, and the overall structural strength of the outer cover 4 can be improved.

[0089] Referring to Figures 1 to 12 As shown, in some embodiments, the air outlet duct 45 is connected to the clothes treatment drum 2 through the flexible buffer pipe 6.

[0090] The flexible buffer pipe 6 is connected to the clothes treatment drum 2 through the air outlet air duct 45. The connection and assembly of the air outlet air duct 45 and the clothes treatment drum 2 can be facilitated, and the vibration of the clothes treatment drum 2 during rotation can be buffered by the flexible buffer pipe 6, so that the vibration of the clothes treatment drum 2 is not directly transmitted to the outer cover 4 and the fan 3, and the outer cover 4 and the fan 3 are not damaged by vibration.

[0091] For example, the flexible buffer pipe 6 can be a tubular structure made of a material with low hardness and high flexibility and capable of vibrating and contracting to effectively buffer the vibration. For example, the flexible buffer pipe 6 can be a rubber bellows or a silicone bellows. The rubber bellows or the silicone bellows can effectively buffer the vibration of the clothes treatment drum 2, so as to prevent the outer cover 4 and the fan 3 from being damaged by vibration.

[0092] Referring to Figures 1 to 12 In some embodiments, the air duct state switching piece 8 is arranged in the air outlet air duct 45, and the air duct state switching piece 8 is rotatable in the air outlet air duct 45 to control the connection and disconnection between the air outlet air duct 45 and the clothes treatment drum 2.

[0093] That is, the air duct state switching piece 8 is arranged in the air outlet air duct 45, and the air duct state switching piece 8 is rotatable to make the inner cavity of the clothes treatment drum 2 and the air outlet air duct 45 in a communication state or in a state of being cut off from communication.

[0094] Specifically, when the clothes treatment drum 2 is used for washing clothes, the inner cavity of the clothes treatment drum 2 and the air outlet air duct 45 are cut off from communication, so as to prevent the washing water or foam in the clothes treatment drum 2 from overflowing through the air outlet air duct 45, thereby affecting the washing operation.

[0095] When the clothes in the clothes treatment drum 2 are washed and the clothes are not taken out from the clothes treatment drum 2 in time, the inner cavity of the clothes treatment drum 2 and the air outlet air duct 45 are communicated at this time, so that the external air flows into the clothes treatment drum 2 through the air inlet 41 and the air outlet 42 to dry the clothes in the clothes treatment drum 2, thereby preventing the clothes from being placed in a dark and humid environment, so as to prevent the clothes from producing odor or bacteria breeding to cause harm to human body.

[0096] For example, the air duct state switching piece 8 specifically includes a rotatable blocking plate and a sealing piece arranged on one side of the blocking plate. The sealing piece is sealed to the air outlet air duct 45 under the driving of the blocking plate, so as to cut off the communication between the inner cavity of the clothes treatment drum 2 and the air outlet air duct 45.

[0097] In some embodiments, the outer cover 4 is further provided with a driving assembly, the driving assembly is connected with the air duct state switching piece 8, and the driving assembly is used for driving the air duct state switching piece 8 to rotate.

[0098] The driving assembly is arranged to drive the air duct state switching piece 8 to rotate, so as to realize the connection and disconnection between the air outlet air duct 45 and the clothes treatment cylinder 2, and the operation is convenient.

[0099] Referring to Figures 5 to 8 illustrated, in some embodiments, the driving assembly includes a driving member 81 and an intermediate transmission member 82. The driving member 81 is located outside the air outlet air duct 45, the driving member 81 is connected with the air duct state switching piece 8 through the intermediate transmission member 82, the air duct wall of the air outlet air duct 45 is provided with a avoiding hole 84, the intermediate transmission member 82 is arranged in the avoiding hole 84, and the intermediate transmission member 82 is sealingly arranged between the avoiding hole 84 and the hole wall.

[0100] For example, the driving member 81 can be a driving motor. The driving motor is arranged to drive the air duct state switching piece 8 to rotate, and the operation is simple, fast and high in automation. Of course, in other implementations, the driving member 81 can also be a driving oil cylinder.

[0101] That is, by arranging the driving member 81 outside the air outlet air duct 45 and connecting the driving member 81 with the air duct state switching piece 8 through the intermediate transmission member 82, the driving member 81 can be avoided to be arranged in the air outlet air duct 45 to occupy the space in the air outlet air duct and affect the air flow. By sealingly arranging the intermediate transmission member 82 and the avoiding hole 84, the air flowing in the air outlet air duct 45 can be prevented from leaking out, and the air drying operation in the clothes treatment cylinder 2 can be affected.

[0102] In specific implementation, when the air duct state switching piece 8 needs to be driven to rotate to realize the connection or disconnection between the air outlet air duct 45 and the clothes treatment cylinder 2, the driving member 81 drives the intermediate transmission member 82 to rotate, and drives the air duct state switching piece 8 to rotate through the intermediate transmission member 82, so as to realize the stable transmission of rotation, which is beneficial to realize the stable rotation of the air duct state switching piece 8, and further makes the operation response of the air duct state switching piece 8 to realize the connection or disconnection between the air outlet air duct 45 and the clothes treatment cylinder 2 more accurate.

[0103] For example, the intermediate transmission member 82 can be a coupling, and a sealing structure such as a sealing ring or sealing grease can be arranged between the intermediate transmission member 82 and the avoiding hole for sealing.

[0104] Continuing to refer to Figures 5 to 8 illustrated, in some embodiments, the outer cover 4 is provided with a travel switch 83, and the driving assembly is provided with a toggle member. When the air duct state switching piece 8 is rotated to disconnect the air outlet air duct 45 and the clothes treatment cylinder 2, the toggle member is driven by the driving assembly to change the state of the travel switch 83.

[0105] In a specific implementation, the travel switch 83 is arranged outside the air outlet air duct 45, and a toggle member is arranged on the driving assembly, so that when the air duct state switching member 8 is rotated to cut off the communication between the air outlet air duct 45 and the laundry treatment drum 2, the toggle member can be driven by the driving assembly to change the state of the travel switch 83, so as to determine that the air duct state switching member 8 has been rotated to the position, and thus it can be ensured that the air outlet air duct 45 and the laundry treatment drum 2 are in a reliable state of cutting off the communication, and the washing water or foam in the laundry treatment drum 2 is prevented from overflowing through the air outlet air duct 45 to affect the washing operation in the laundry treatment drum 2.

[0106] For example, the toggle member can be arranged on the intermediate transmission member 82 of the driving assembly, so that when the air duct state switching member 8 is rotated to cut off the communication between the air outlet air duct 45 and the laundry treatment drum 2, the toggle member can be driven by the intermediate transmission member 82 to change the state of the travel switch 83, so as to determine that the air duct state switching member 8 has been rotated to the position, and thus it can be ensured that the air outlet air duct 45 and the laundry treatment drum 2 are in a reliable state of cutting off the communication, and the washing water or foam in the laundry treatment drum 2 is prevented from overflowing through the air outlet air duct 45 to affect the washing operation in the laundry treatment drum 2.

[0107] For example, when the air duct state switching member 8 is rotated to the position, at this time the toggle member can switch the travel switch 83 from the closed state to the open state, and thus the state of the travel switch 83 can be determined to determine whether the air duct state switching member 8 is rotated to the position.

[0108] For example, the travel switch 83 can be a common micro switch.

[0109] Referring to Figures 9 to 12 In some embodiments, the outer cover 4 is provided with a lead terminal placement area 47 for placing a lead terminal, and the lead terminal placement area 47 is located on one side of the outer cover 4, and the lead in the cabinet 1 is connected with the lead terminal.

[0117] By providing the flexible buffer pipe 6, the flexible buffer pipe 6 can be connected in the mounting opening 51 on the door seal 5 of the clothes treatment drum 2, so as to realize reliable communication between the flexible buffer pipe 6 and the inner cavity of the clothes treatment drum 2.

[0118] In specific implementation, the front side of the clothes treatment drum 2 (the front side is defined as the direction in which the clothes treatment equipment faces the user) can be provided with a clothes feeding opening, and the clothes feeding opening can be provided with a door seal 5 to connect a door body for closing the clothes feeding opening. The door seal 5 can be provided with a mounting opening 51, and the mounting opening 51 is in communication with the inner cavity of the clothes treatment drum 2 and the flexible buffer pipe 6, respectively.

[0119] Referring to Figures 1 to 12 In some embodiments, the box body 1 is provided with an exhaust pipe 9, the air inlet end of the exhaust pipe 9 is in communication with the inner cavity of the clothes treatment drum 2, and the air outlet end of the exhaust pipe 9 is in communication with the outside.

[0120] By providing the exhaust pipe 9, external air can flow into the clothes treatment drum 2 under the action of the fan 3 and then be discharged through the exhaust pipe 9, so as to realize the circulation of the air in the clothes treatment drum 2, and better realize the air drying of the clothes treatment drum 2, prevent the formation of a dark and humid environment in the clothes treatment drum 2, and thus cause the clothes to produce odor or bacteria breeding to harm the human body.

[0121] In specific implementation, one end of the exhaust pipe 9 forms an air inlet end in communication with the inner cavity of the clothes treatment drum 2, and the other end of the exhaust pipe 9 forms an air outlet end in communication with the outside. The air inlet end and the air outlet end are in communication, so that the air entering the clothes treatment drum 2 can be discharged to the outside of the clothes treatment equipment through the exhaust pipe 9 after air drying the clothes treatment drum 2 in the clothes treatment drum 2.

[0122] That is, the outside air enters into the clothes treatment drum 2 through the fresh air shell, and then the air in the clothes treatment drum 2 after being dried by the air is discharged through the exhaust pipe 9, so as to realize the circulation of the air in the clothes treatment drum 2, so as to avoid the formation of a dark and humid environment in the clothes treatment drum 2 to cause odor or bacteria breeding.

[0123] In addition, the exhaust pipe 9 can be a plastic hose or a silica gel hose, so that the exhaust pipe 9 has a certain flexibility, so that it can be conveniently bent and arranged in the clothes treatment equipment, so as to save the internal space of the clothes treatment equipment.
