Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of clothing treatment, and more specifically, to a barrel assembly and a clothing treatment device. Background Art

[0002] Heat pump dryers have greatly improved people's quality of life, enabling the effect of wearing clothes immediately after drying, and having energy-saving characteristics at the same time. However, due to improper design of the air outlet structure of the barrel, the air resistance is often too large during air outlet, affecting the air output volume, and greatly weakening the drying efficiency of the heat pump dryer. Summary of the Invention

[0003] Embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of the embodiments of the present invention provides a barrel assembly.

[0005] A second aspect of the embodiments of the present invention provides a clothing treatment device.

[0006] In view of this, according to the first aspect of the embodiments of the present invention, there is provided a barrel assembly, including a first barrel, a second barrel, and an air outlet. Among them, the second barrel is located inside the first barrel; the air outlet is provided on the first barrel, and the air outlet faces the space between the bottom wall of the first barrel and the bottom wall of the second barrel.

[0007] The barrel assembly provided by the embodiments of the present invention is specifically used for a clothing treatment device with a drying function, such as a dryer. The barrel assembly includes a first barrel and a second barrel located inside the first barrel. An air outlet is provided on the wall surface of the first barrel, so that the air outlet is directly connected to the space between the first barrel and the second barrel, and then can be connected to the second barrel through the air outlet structure on the wall surface of the second barrel, forming an output path for the wet and cold air in the second barrel. Among them, the opening of the second barrel faces the opening of the first barrel, forming a laundry inlet for the user to put clothes into the second barrel. The wall surface of the first barrel facing its opening is its bottom wall. Similarly, the wall surface of the second barrel facing its opening is its bottom wall. By setting the air outlet to face the space between the bottom wall of the first barrel and the bottom wall of the second barrel, the gap between the first barrel and the second barrel is the largest at this place, and there is no other structure in this part of the space, so it will not block the air outlet. Therefore, it helps to reduce the flow resistance of the air flow here, reduce the flow loss, thereby increasing the air output volume, improving the drying efficiency of the clothing treatment device using this barrel assembly, and helping to reduce noise and improve the use comfort.

[0008] Specifically, for a cyclic drying system, the air outlet can be used to communicate with the air supply component of the laundry treatment device, so as to introduce the wet and cold air in the barrel assembly into the air supply component, and after dehumidification and temperature rise, it is sent back into the barrel assembly to realize laundry drying. For an exhaust drying system, the air outlet can be used to directly discharge the wet and cold air in the barrel assembly into the environment.

[0009] In addition to the drying function, the laundry treatment device can also realize the washing function and the dehydration function, that is, the laundry treatment device is an integrated washer-dryer. The outer first barrel remains stationary and is used for storing water, and the inner second barrel is used for accommodating laundry and can rotate relative to the first barrel. The first barrel and the second barrel are communicated to allow the washing water to enter the second barrel, and the second barrel rotates according to a certain rule, enabling the laundry to be in full contact with the washing water to realize laundry washing. After washing is completed, the second barrel rotates, and part of the water on the laundry can be thrown out under the action of centrifugal force to realize laundry dehydration.

[0010] In addition, the barrel assembly provided according to the above technical solution of the present invention further has the following additional technical features:

[0011] In a possible design, the air outlet is provided on the side wall of the first barrel.

[0012] In this design, by specifically arranging the air outlet on the side wall rather than the bottom wall of the first barrel, it can not only meet the requirement of reducing the flow resistance of the air flow, but also arrange the air duct connecting the barrel assembly at the side wall of the first barrel, which helps to reduce the difficulty of air duct arrangement and improve the assembly efficiency. In addition, this design does not need to occupy the space behind the bottom wall of the first barrel, which helps to reduce the size of the laundry treatment device in this direction, thereby realizing the miniaturized design of the laundry treatment device, facilitating the arrangement of the laundry treatment device indoors or embedding it in a laundry cabinet, expanding the scope of application of the product, and helping to improve the product competitiveness.

[0013] In a possible design, the barrel assembly further includes: a first air outlet part, located at the bottom wall of the second barrel, and the first air outlet part includes at least one first air outlet hole.

[0014] In this design, the barrel assembly further includes a first air outlet portion located at the bottom wall of the second barrel, that is, the air inside the second barrel can be discharged through the bottom wall of the second barrel and directly reach the space between the bottom wall of the first barrel and the bottom wall of the second barrel, and then be discharged through the air outlet. This can effectively reduce the blockage during the air flow movement, thereby reducing the air resistance, reducing the flow loss, increasing the air output, improving the drying efficiency of the laundry treatment device using this barrel assembly, and helping to reduce noise and improve the use comfort. By providing at least one first air outlet hole in the first air outlet portion, such as a plurality of small-sized first air outlet holes instead of a large-sized opening, it can not only meet the air outlet requirement but also reduce the structural damage to the second barrel, helping to ensure the structural strength of the second barrel, improving the working reliability of the barrel assembly, and extending the service life of the product. In addition, there must be a certain distance between two adjacent first air outlet holes. Therefore, compared with a large-sized opening, under the same cross-sectional area of the air flow channel, the area covered by the entire first air outlet portion is larger, which helps to extract the air at different positions inside the second barrel, enabling the air flow to pass through the clothes at different positions, thus improving the drying efficiency of the laundry treatment device using this barrel assembly.

[0015] In a possible design, the bottom wall of the second barrel is recessed towards the bottom wall of the first barrel to form a recess portion, the first air outlet portion includes the recess portion, and at least one first air outlet hole is provided on the bottom wall of the recess portion.

[0016] In this design, the first air outlet portion further includes a recess portion, and its bottom wall provides a setting position for the first air outlet hole. Since the recess portion itself can enhance the structural strength of the bottom wall of the second barrel in terms of shape, therefore, by opening the first air outlet hole in the recess portion, it helps to fully reduce the structural strength damage caused to the second barrel by opening the first air outlet hole, ensuring that the second barrel has sufficient structural strength, improving the working reliability of the barrel assembly, and extending the service life of the product. In addition, since the recess portion is specifically recessed towards the bottom wall of the first barrel, that is, the opening faces the inside of the second barrel, the air inside the second barrel can first flow to the recessed area formed by the recess portion and then flow out through the first air outlet hole. That is to say, the recess portion can play a role in guiding the air flow, guiding the air flow to gradually flow towards the first air outlet hole, helping to further reduce the air flow resistance, reduce the flow loss, increase the air output, improve the drying efficiency of the laundry treatment device using this barrel assembly, and help to reduce noise and improve the use comfort.

[0017] In a possible design, the barrel assembly further includes: a second air outlet portion located on the side wall of the second barrel, and the second air outlet portion includes at least one second air outlet hole.

[0018] In this design, the barrel assembly further includes a second air outlet portion located on the side wall of the second barrel, that is, the air inside the second barrel can be discharged through the side wall of the second barrel. First, it flows along the generatrix direction of the second barrel to the bottom wall of the second barrel, and then is discharged through the air outlet. This can effectively reduce the blockage during the air flow movement, thereby reducing the air resistance, reducing the flow loss, increasing the air output, improving the drying efficiency of the laundry processing device using this barrel assembly, and helping to reduce noise and improve the use comfort. By providing at least one second air outlet hole in the second air outlet portion, such as a plurality of small-sized second air outlet holes instead of a large-sized opening, it can not only meet the air outlet requirement but also reduce the structural damage to the second barrel, help ensure the structural strength of the second barrel, improve the working reliability of the barrel assembly, and extend the service life of the product. In addition, there must be a certain distance between two adjacent second air outlet holes. Therefore, compared with a large-sized opening, in the case of the same cross-sectional area of the air outlet flow channel, the area covered by the entire second air outlet portion is larger, which helps to draw out the air at different positions inside the second barrel, enabling the air flow to flow through the laundry at different positions, thus improving the drying efficiency of the laundry processing device using this barrel assembly.

[0019] Specifically, the above-mentioned first air outlet portion and the second air outlet portion can be provided simultaneously, so that the air inside the second barrel can be discharged through the bottom wall and the side wall of the second barrel at the same time. The air flow discharged from the first air outlet portion on the bottom wall of the second barrel flows upward, and the air flow discharged from the second air outlet portion on the side wall of the second barrel flows backward and converges and is discharged at the air outlet. At this time, whether it is the air flow discharged from the first air outlet portion or the air flow discharged from the second air outlet portion, its flow path is shorter, with less occlusion and bending. Therefore, generally speaking, the flow resistance is smaller, the flow loss is less, and the air volume is larger at the same driving motor speed, which can improve the drying efficiency of the laundry processing device using this barrel assembly and the noise is smaller, which can improve the use comfort of the laundry processing device using this barrel assembly.

[0020] In a possible design, the number of the second air outlet portions is at least two, and the at least two second air outlet portions are distributed at intervals along the circumferential direction of the second barrel.

[0021] In this design, by configuring at least two second air outlets to be circumferentially spaced along the second barrel, when some of the second air outlets are located at the bottom of the clothes in the barrel and covered by the clothes as the second barrel rotates, it can ensure that air can be discharged through the uncovered second air outlets, ensuring the effective discharge of air and guaranteeing the normal realization of the drying function. For the uncovered second air outlets, the circumferentially spaced arrangement can also make the air flow out from multiple positions in the circumferential direction, enabling the air flow to flow through clothes at different positions, thereby improving the drying efficiency of the clothes treatment device applying this barrel assembly. In addition, by dispersedly arranging the second air outlets, the structural strength at various circumferential parts of the second barrel can be made uniform, reducing the local strength weakening caused by the concentrated arrangement of the second air outlets, which helps to improve the working reliability of the barrel assembly and extend the service life of the product.

[0022] In a possible design, the barrel assembly further includes: an air outlet pipe connected to the air outlet, and the air outlet pipe is located on the outer wall surface of the first barrel.

[0023] In this design, by arranging an air outlet pipe connected to the air outlet on the outer wall surface of the first barrel, it can conveniently connect the air outlet with other structures of the clothes treatment device, such as the air duct, through the air outlet pipe, which helps to reduce the assembly difficulty and the sealing difficulty at the connection, and further reduces the risk of air leakage caused by the sealing failure at the connection, improving the working reliability of the clothes treatment device applying this barrel assembly.

[0024] In a possible design, the barrel assembly further includes a door seal and a return air outlet. The door seal is connected to the opening of the first barrel; the return air outlet is arranged on the door seal.

[0025] In this design, the barrel assembly further includes a door seal located at the opening of the first barrel, which can cooperate with the door body of the clothes treatment device to achieve the sealing of the barrel assembly and prevent water leakage from the barrel assembly. By arranging a return air outlet on the door seal, that is, enabling the warm and dry air used for drying clothes to enter the second barrel through the return air outlet on the door seal, the door seal can be used for air return, which helps to reduce the structural damage to the first barrel. And the door seal is usually made of rubber structure and has low requirements for structural strength. Therefore, the design of air return through the door seal can improve the overall structural strength of the barrel assembly. In addition, the door seal is located at the clothes inlet of the barrel assembly, and the air outlet is arranged as described above towards the space between the bottom wall of the first barrel and the bottom wall of the second barrel, that is, close to the bottom wall of the first barrel or directly arranged on the bottom wall of the first barrel, so as to maximize the distance between the return air outlet and the air outlet, which helps to extend the flow path of the air flow, enable the warm and dry air entering the second barrel to fully contact the clothes to be dried, and further improve the drying efficiency and reduce the energy consumption. Specifically, a return air duct protruding from the outer side wall of the door seal can be arranged at the return air outlet for easy assembly.

[0026] According to a second aspect of the embodiments of the present invention, a laundry treatment apparatus is provided, which includes a housing and a barrel assembly provided in any of the above technical solutions. The barrel assembly is located inside the housing.

[0027] The laundry treatment apparatus provided by the embodiments of the present invention includes a barrel assembly provided in any of the above technical solutions, and thus has all the beneficial effects of the barrel assembly, which will not be elaborated here.

[0028] In a possible design, the housing includes a side plate, and the air outlet is located between the side plate and the central axis of the barrel assembly.

[0029] In this design, by arranging the air outlet between the side plate of the housing and the central axis of the barrel assembly, that is, making the air outlet eccentrically arranged, more continuous space can be vacated to facilitate the arrangement of other structures of the laundry treatment apparatus, which helps to achieve a compact layout of the laundry treatment apparatus.

[0030] Further, in the case where an air return opening is provided at the door seal of the barrel assembly, the distance between the air outlet and the side plate can be made smaller than the distance between the air return opening and the side plate, so that the air outlet and the air return opening are inclined to each other. Specifically, the projection of the connection line between the center point of the air outlet and the center point of the air return opening in the horizontal plane intersects with the projection of the central axis of the barrel assembly in the horizontal plane, which helps to further increase the distance between the air return opening and the air outlet, extend the flow path of the air flow, and enable the warm and dry air entering the second barrel to fully contact the clothes to be dried, thereby improving the drying efficiency and reducing the energy consumption.

Detailed embodiments

[0042] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0043] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0044] The following refers to Figures 1 to 7 to describe the barrel assembly 100 and the laundry treatment apparatus provided according to some embodiments of the present invention.

[0045] As Figure 7 shown, an embodiment of the first aspect of the present invention provides a barrel assembly 100, including a first barrel 110, a second barrel 120 and an air outlet 130. Among them, the second barrel 120 is located inside the first barrel 110; the air outlet 130 is provided on the first barrel 110, and the air outlet 130 faces the space between the bottom wall of the first barrel 110 and the bottom wall of the second barrel 120.

[0046] The barrel assembly 100 provided by the embodiment of the present invention is specifically used for a laundry treatment device with a drying function, such as a dryer. The barrel assembly 100 includes a first barrel 110 and a second barrel 120 located inside the first barrel 110. An air outlet 130 is provided on the wall surface of the first barrel 110, so that the air outlet 130 is directly communicated with the space between the first barrel 110 and the second barrel 120, and then can be communicated with the second barrel 120 through the air outlet structure on the wall surface of the second barrel 120, forming an output path for the wet and cold air in the second barrel 120. Wherein, the opening of the second barrel 120 faces the opening of the first barrel 110, forming a clothing inlet for the user to put clothes into the second barrel 120. The wall surface of the first barrel 110 facing its opening is its bottom wall. Similarly, the wall surface of the second barrel 120 facing its opening is its bottom wall. By arranging the air outlet 130 towards the space between the bottom wall of the first barrel 110 and the bottom wall of the second barrel 120, the gap between the first barrel 110 and the second barrel 120 is the largest at this place, and there is no other structure in this part of the space, so it will not block the air outlet 130, which helps to reduce the flow resistance of the air flow here, reduce the flow loss, thereby increasing the air volume, improving the drying efficiency of the laundry treatment device applying the barrel assembly 100, and helping to reduce noise and improve the use comfort.

[0047] Specifically, for a circulating drying system, the air outlet 130 can be used to communicate with the air supply assembly 300 of the laundry treatment device to introduce the wet and cold air in the barrel assembly 100 into the air supply assembly 300, and after dehumidification and temperature increase, it is sent back into the barrel assembly 100 to realize clothes drying. For an exhaust drying system, the air outlet 130 can be used to directly discharge the wet and cold air in the barrel assembly 100 into the environment.

[0048] In addition to the drying function, the laundry treatment device can also realize the washing function and the dehydration function, that is, the laundry treatment device is a washing and drying integrated machine. The outer first barrel 110 remains stationary and is used for storing water. The inner second barrel 120 is used for accommodating clothes and can rotate relative to the first barrel 110. The first barrel 110 and the second barrel 120 are communicated to allow washing water to enter the second barrel 120. The second barrel 120 rotates according to a certain rule, which can make the clothes fully contact with the washing water to realize clothes washing. After washing, the second barrel 120 rotates, and part of the water on the clothes can be thrown out under the action of centrifugal force to realize clothes dehydration.

[0049] As Figure 7 shown, in some embodiments, the air outlet 130 is provided on the side wall of the first barrel 110.

[0050] In this embodiment, by specifically arranging the air outlet 130 on the side wall rather than the bottom wall of the first barrel body 110, it can not only meet the requirement of reducing the flow resistance of the air flow, but also correspondingly arrange the air duct 302 communicating with the barrel body assembly 100 on the side wall of the first barrel body 110, which helps to reduce the layout difficulty of the air duct 302 and improve the assembly efficiency. In addition, this design does not need to occupy the space behind the bottom wall of the first barrel body 110, which helps to reduce the size of the clothing treatment device in this direction, thus realizing the miniaturized design of the clothing treatment device, facilitating the arrangement of the clothing treatment device indoors or embedding it in a laundry cabinet, expanding the applicable range of the product, and helping to enhance the product competitiveness.

[0051] As Figure 7 shown, in some embodiments, the barrel body assembly 100 further includes: a first air outlet part 140, located on the bottom wall of the second barrel body 120, and the first air outlet part 140 includes at least one first air outlet hole 142.

[0052] In this embodiment, the barrel body assembly 100 further includes a first air outlet part 140 located on the bottom wall of the second barrel body 120, that is, the air in the second barrel body 120 can be discharged through the bottom wall of the second barrel body 120 and directly reach the space between the bottom wall of the first barrel body 110 and the bottom wall of the second barrel body 120, and then be discharged through the air outlet 130. This can effectively reduce the blockage during the movement of the air flow, thereby reducing the wind resistance, reducing the flow loss, increasing the air output volume, improving the drying efficiency of the clothing treatment device applying the barrel body assembly 100, and helping to reduce the noise and improve the use comfort. By providing at least one first air outlet hole 142, such as a plurality of small-sized first air outlet holes 142, in the first air outlet part 140 instead of a large-sized opening, it can not only meet the air outlet requirement, but also reduce the structural damage to the second barrel body 120, which helps to ensure the structural strength of the second barrel body 120, improve the working reliability of the barrel body assembly 100, and extend the service life of the product. In addition, there must be a certain distance between two adjacent first air outlet holes 142. Therefore, compared with a large-sized opening, in the case of the same cross-sectional area of the air outlet flow channel, the area covered by the entire first air outlet part 140 is larger, which helps to extract the air at different positions in the second barrel body 120, so that the air flow can flow through the clothing at different positions, thereby improving the drying efficiency of the clothing treatment device applying the barrel body assembly 100.

[0053] As Figure 7 shown, in some embodiments, the bottom wall of the second barrel body 120 is recessed towards the bottom wall of the first barrel body 110 to form a recessed part 144, the first air outlet part 140 includes the recessed part 144, and at least one first air outlet hole 142 is provided on the bottom wall of the recessed part 144.

[0054] In this embodiment, the first air outlet part 140 further includes a recessed part 144, the bottom wall of which provides a setting position for the first air outlet hole 142. Since the recessed part 144 itself can enhance the structural strength of the bottom wall of the second barrel body 120 in terms of shape, therefore, by opening the first air outlet hole 142 in the recessed part 144, it helps to fully reduce the damage to the structural strength of the second barrel body 120 caused by opening the first air outlet hole 142, ensures that the second barrel body 120 has sufficient structural strength, improves the working reliability of the barrel body assembly 100, and extends the service life of the product. In addition, since the recessed part 144 is specifically recessed towards the bottom wall of the first barrel body 110, that is, the opening faces the inside of the second barrel body 120, the air inside the second barrel body 120 can first flow to the recessed area formed by the recessed part 144 and then flow out through the first air outlet hole 142. That is to say, the recessed part 144 can play a role in guiding the flow, guiding the air flow to gradually flow towards the first air outlet hole 142, which helps to further reduce the air flow resistance, reduce the flow loss, increase the air output, improve the drying efficiency of the clothing treatment device applying the barrel body assembly 100, and helps to reduce noise and improve the use comfort.

[0055] As Figure 6 and Figure 7 shown, in some embodiments, the barrel body assembly 100 further includes: a second air outlet part 150, located on the side wall of the second barrel body 120, and the second air outlet part 150 includes at least one second air outlet hole 152.

[0056] In this embodiment, the barrel body assembly 100 further includes a second air outlet part 150 located on the side wall of the second barrel body 120, that is, the air inside the second barrel body 120 can be discharged through the side wall of the second barrel body 120, first flows along the generatrix direction of the second barrel body 120 to the bottom wall of the second barrel body 120, and then is discharged through the air outlet 130, which can effectively reduce the blockage during the air flow movement, thereby reducing the wind resistance, reducing the flow loss, increasing the air output, improving the drying efficiency of the clothing treatment device applying the barrel body assembly 100, and helps to reduce noise and improve the use comfort. By providing at least one second air outlet hole 152 in the second air outlet part 150, such as a plurality of small-sized second air outlet holes 152 instead of a large-sized opening, it can not only meet the air outlet requirement but also reduce the structural damage to the second barrel body 120, which helps to ensure the structural strength of the second barrel body 120, improve the working reliability of the barrel body assembly 100, and extend the service life of the product. In addition, there must be a certain distance between two adjacent second air outlet holes 152. Therefore, compared with a large-sized opening, in the case of the same cross-sectional area of the air outlet flow channel, the area covered by the entire second air outlet part 150 is larger, which helps to extract the air at different positions inside the second barrel body 120, so that the air flow can flow through the clothing at different positions, thereby improving the drying efficiency of the clothing treatment device applying the barrel body assembly 100.

[0057] Specifically, as Figure 7 shown, the first air outlet part 140 and the second air outlet part 150 can be set simultaneously, so that the air in the second barrel body 120 can be discharged through the bottom wall and the side wall of the second barrel body 120 at the same time. The air flow discharged from the first air outlet part 140 on the bottom wall of the second barrel body 120 flows upward, and the air flow discharged from the second air outlet part 150 on the side wall of the second barrel body 120 flows backward, and converges and discharges at the air outlet 130. At this time, whether it is the air flow discharged from the first air outlet part 140 or the air flow discharged from the second air outlet part 150, the flow path to reach the air outlet 130 is shorter, and there is less occlusion and bending. Therefore, generally speaking, the flow resistance is smaller, the flow loss is less, the air volume is larger at the same driving motor speed, the drying efficiency of the laundry treatment device applying the barrel assembly 100 can be improved, and the noise is smaller, and the use comfort of the laundry treatment device applying the barrel assembly 100 can be improved.

[0058] As Figure 6 shown, in some embodiments, the number of the second air outlet parts 150 is at least two, and the at least two second air outlet parts 150 are distributed at intervals along the circumferential direction of the second barrel body 120.

[0059] In this embodiment, by configuring the second air outlet parts 150 as at least two distributed at intervals along the circumferential direction of the second barrel body 120, when some of the second air outlet parts 150 are located at the bottom of the clothes in the barrel and covered by the clothes as the second barrel body 120 rotates, it can be ensured that the air can be discharged through the uncovered second air outlet parts 150, ensuring the effective discharge of the air and ensuring the normal realization of the drying function. For the uncovered second air outlet parts 150, the arrangement of being distributed at intervals along the circumferential direction can also make the air flow out from multiple positions in the circumferential direction, so that the air flow can flow through the clothes at different positions, thereby improving the drying efficiency of the laundry treatment device applying the barrel assembly 100. In addition, by dispersedly arranging the second air outlet parts 150, the structural strength at each part in the circumferential direction of the second barrel body 120 can be made uniform, reducing the local strength weakening caused by the concentrated arrangement of the second air outlet parts 150, which helps to improve the working reliability of the barrel assembly 100 and extend the service life of the product.

[0060] As Figure 6 and Figure 7 shown, in some embodiments, the barrel assembly 100 further includes: an air outlet pipe 160, which is connected to the air outlet 130, and the air outlet pipe 160 is located on the outer wall surface of the first barrel body 110.

[0061] In this embodiment, by providing an air outlet pipe 160 connected to the air outlet 130 on the outer wall surface of the first barrel body 110, the air outlet 130 can be conveniently communicated with other structures of the clothing treatment device, such as the air duct 302, through the air outlet pipe 160. This helps to reduce the assembly difficulty and the sealing difficulty at the connection, thereby reducing the risk of air leakage caused by the sealing failure at the connection and improving the working reliability of the clothing treatment device applying the barrel assembly 100.

[0062] As Figure 5 and Figure 6 shown, in some embodiments, the barrel assembly 100 further includes a door seal 170 and a return air outlet 180. The door seal 170 is connected to the opening of the first barrel body 110; the return air outlet 180 is provided on the door seal 170.

[0063] In this embodiment, the barrel assembly 100 further includes a door seal 170 located at the opening of the first barrel body 110, which can cooperate with the door body of the clothing treatment device to achieve the sealing of the barrel assembly 100 and prevent the water in the barrel assembly 100 from leaking. By providing a return air outlet 180 at the door seal 170, that is, enabling the warm and dry air used for drying clothes to enter the second barrel body 120 through the return air outlet 180 at the door seal 170, the door seal 170 can be used to achieve air return, which helps to reduce the structural damage to the first barrel body 110. The door seal 170 is usually made of rubber and has low requirements for structural strength. Therefore, the design of air return through the door seal 170 can improve the overall structural strength of the barrel assembly 100. In addition, the door seal 170 is located at the clothing inlet of the barrel assembly 100, and the air outlet 130 is arranged as described above towards the space between the bottom wall of the first barrel body 110 and the bottom wall of the second barrel body 120, that is, close to the bottom wall of the first barrel body 110 or directly provided on the bottom wall of the first barrel body 110, so as to maximize the distance between the return air outlet 180 and the air outlet 130, which helps to extend the flow path of the air flow, enable the warm and dry air entering the second barrel body 120 to fully contact the clothes to be dried, and thus improve the drying efficiency and reduce the energy consumption. Specifically, a return air pipe 190 protruding from the outer side wall of the door seal 170 can be provided at the return air outlet 180 for easy assembly.

[0064] As Figures 1 to 5 shown, an embodiment of the second aspect of the present invention provides a clothing treatment device, including a housing 200 and the barrel assembly 100 provided in any of the above embodiments. Among them, the barrel assembly 100 is located inside the housing 200.

[0065] The clothing treatment device provided by the embodiment of the present invention includes the barrel assembly 100 provided in any of the above embodiments, and thus has all the beneficial effects of the barrel assembly 100, which will not be elaborated here.

[0066] As Figure 2 andFigure 6 As shown, in some embodiments, the housing 200 includes side plates 202, and the air outlet 130 is located between the side plates 202 and the central axis of the barrel assembly 100.

[0067] In this embodiment, by arranging the air outlet 130 between the side plates 202 of the housing 200 and the central axis of the barrel assembly 100, that is, by eccentrically arranging the air outlet 130, more continuous space can be created to facilitate the arrangement of other structures of the laundry treatment device, which helps to achieve a compact layout of the laundry treatment device.

[0068] Further, for the case where an air return port 180 is provided at the door seal 170 of the barrel assembly 100, the distance between the air outlet 130 and the side plate 202 can be made smaller than the distance between the air return port 180 and the side plate 202, so that the air outlet 130 and the air return port 180 are inclined to each other. Specifically, the projection of the line connecting the center point of the air outlet 130 and the center point of the air return port 180 in the horizontal plane intersects the projection of the central axis of the barrel assembly 100 in the horizontal plane, which helps to further increase the distance between the air return port 180 and the air outlet 130, extend the flow path of the air flow, enable the warm and dry air entering the second barrel 120 to fully contact the clothes to be dried, and thus improve the drying efficiency and reduce the energy consumption.

[0069] As Figure 3 、 Figure 4 and Figure 7 As shown, in some embodiments, the laundry treatment device further includes a blowing assembly 300, the blowing assembly 300 is located inside the housing 200, and the blowing assembly 300 is communicated with the air outlet 130 of the barrel assembly 100.

[0070] In this embodiment, the blowing assembly 300 is communicated with the air outlet 130 of the barrel assembly 100, which can dehumidify and warm up the air led out through the air outlet 130 and send it back to the barrel assembly 100 to achieve clothes drying. That is to say, the laundry treatment device provided by the embodiments of the present invention adopts a circulating drying system.

[0071] Specifically, the air supply assembly 300 includes an air duct 302, an evaporator 304, and a condenser 306. Both ends of the air duct 302 are connected to the barrel assembly 100 in a communicating manner, and both the evaporator 304 and the condenser 306 are located inside the air duct 302. The first end of the air duct 302 is connected to the air outlet 130 of the barrel assembly 100, and the second end of the air duct 302 is connected to the air return port 180 of the barrel assembly 100. Both the evaporator 304 and the condenser 306 have heat exchange tubes through which the refrigerant passes. When the air flow passes over the surface of the heat exchange tubes, heat can be exchanged with the refrigerant inside the heat exchange tubes. The evaporator 304 is located between the first end of the air duct 302 and the condenser 306, that is, the evaporator 304 is located upstream of the condenser 306. The wet and cold air entering the air duct 302 from the barrel assembly 100 first contacts the evaporator 304. The refrigerant in the evaporator 304 evaporates and absorbs heat, taking away the heat of the wet and cold air, causing the water vapor in the wet and cold air to cool and condense into a liquid state, and then being discharged, which can reduce the humidity of the wet and cold air and achieve dehumidification. The dehumidified dry and cold air then contacts the downstream condenser 306. The refrigerant in the condenser 306 condenses and releases heat, transferring heat to the dry and cold air, causing the dry and cold air to warm up, obtaining warm and dry air. These warm and dry air return to the barrel assembly 100 again through the second end of the air duct 302 and the air return port 180, which can promote the evaporation of the moisture on the clothes, accelerate the drying of the clothes, and at the same time increase the air humidity inside the barrel assembly 100. By repeating this cycle, the drying of the clothes can be achieved.

[0072] By arranging both the evaporator 304 and the condenser 306 inside the air duct 302, rather than introducing the air flow inside the air duct 302 into the space where the evaporator 304 and the condenser 306 are located, it is possible to fully increase the heat exchange area between the air flow and the evaporator 304 and the condenser 306, reduce the cold quantity dissipation of the evaporator 304 and the heat dissipation of the condenser 306, improve the heat exchange efficiency, optimize the dehumidification and temperature increase effect, shorten the time required for drying clothes, and at the same time simplify the product structure, reduce the production cost, and improve the production efficiency.

[0073] Specifically, the air supply component 300 further includes a throttling device 308, such as a capillary tube, connected between the outlet of the condenser 306 and the inlet of the evaporator 304. The laundry treatment device further includes a compressor 400. The compressor 400 is connected to the evaporator 304 and the condenser 306 through a pipeline assembly 500 and can provide power for the circulation of the refrigerant. Specifically, the intake port of the compressor 400 is connected to the outlet of the evaporator 304, and the exhaust port of the compressor 400 is connected to the inlet of the condenser 306, forming a refrigerant circulation path of compressor 400 → condenser 306 → throttling device 308 → evaporator 304 → compressor 400, which constitutes a heat pump system. When the heat pump system operates, the refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor 400. The high-temperature and high-pressure gaseous refrigerant is discharged from the compressor 400 through the exhaust port of the compressor 400 and then enters the condenser 306 to condense and release heat. The high-temperature and high-pressure gaseous refrigerant gradually turns into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows out of the condenser 306 and enters the throttling device 308 for throttling to reduce the temperature and pressure. The high-pressure liquid refrigerant turns into a low-temperature and low-pressure gas-liquid mixed refrigerant. Then, the low-temperature and low-pressure refrigerant flows out of the throttling device 308 and enters the evaporator 304 to absorb heat from the surrounding environment and continuously evaporate, turning into a low-pressure gaseous refrigerant. The low-pressure gaseous refrigerant flows out of the evaporator 304 and then re-enters the compressor 400 through the intake port of the compressor 400 for compression, and so on in a cycle.

[0074] Furthermore, the air supply component 300 further includes a filter element 310 disposed upstream of the evaporator 304 to reduce the risk of fluff and other debris in the air flow entering the air duct 302 adhering to the evaporator 304 and the condenser 306, which helps to ensure the reliable heat exchange of the evaporator 304 and the condenser 306 and improve the heat exchange efficiency.

[0075] Furthermore, the air supply component 300 further includes an air inlet pipe 312. The air inlet pipe 312 is connected between the air outlet 130 and the air duct 302. The air inlet pipe 312 can be used to connect the air duct 302 to the barrel assembly 100, enabling the reliable assembly of the air supply component 300 and the barrel assembly 100. In addition, by using the air inlet pipe 312, after determining the installation position of the air duct 302, it is convenient to connect the air duct 302 to the barrel assembly 100 using the air inlet pipe 312, which helps to improve the flexibility of the installation position of the air duct 302. Specifically, at least part of the pipe section of the air inlet pipe 312 is a corrugated pipe, which helps to improve the vibration resistance performance of the air supply component 300.

[0076] Further, the air supply assembly 300 further includes a fan 314 connected between the second end of the air duct 302 and the air return opening 180. Specifically, the outlet of the fan 314 is connected to the barrel assembly 100. That is to say, the second end of the air duct 302 is connected to the air return opening 180 via the fan 314. By providing the fan 314, power can be provided for the circulation of the air flow, and the air flow direction can be planned. In the case where the air supply assembly 300 includes the aforementioned evaporator 304 and condenser 306, the air flow can be guided to pass through the evaporator 304 first and then through the condenser 306, ensuring that the temperature of the air returning to the barrel assembly 100 is relatively high to ensure the clothing drying effect. By specifically arranging the fan 314 at the second end of the air duct 302, a negative pressure can be formed here, and the air flow can be guided to flow from the first end of the air duct 302 to the second end of the air duct 302 by using the pressure difference, ensuring the stability and reliability of the air flow direction. Specifically, the fan 314 includes a fan volute and an impeller located inside the fan volute, and further includes a motor for driving the impeller to rotate. The inlet and outlet of the fan 314 are specifically the inlet and outlet of the fan volute.
