[0002] In recent years, the washing machine industry has shown a diversified development trend. With the improvement of people's living standards, the concept of healthy, partitioned washing has gradually become a core aspect of washing machine product development. To meet consumers' growing demand for healthy washing, various types of multi-drum washing machines with partitioned washing functions have been developed on the market; in particular, heat pump multi-drum washing machines are popular among consumers due to their superior care and low damage to clothes. In existing technologies, the filter screen at the air outlet of the clothes handling drum is mainly cleaned manually or by spraying. However, neither manual cleaning nor spraying can accurately and promptly assess the degree of filter clogging, leading to untimely or excessively frequent cleaning and incomplete cleaning.

This enables timely cleaning of the filter, preventing excessive clogging that increases airflow resistance during drying or excessively frequent cleaning that wastes water and time. This improves user experience and solves the problems in existing technologies where timely and accurate assessment of filter clogging is not possible, leading to untimely or excessively frequent filter cleaning, or incomplete filter cleaning.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0061] In existing technologies, the filter screen at the air outlet of the garment processing drum is mainly cleaned manually or by spraying. However, neither manual cleaning nor spraying can accurately and promptly assess the degree of clogging of the filter screen, resulting in untimely or excessively frequent cleaning and incomplete cleaning.

[0062] This invention creatively provides a clothing treatment device with a drying function, comprising:

[0063] There are N clothing processing drums, each with an air inlet at its opening and an air outlet on its wall, and each air outlet is equipped with a filter.

[0064] The air intake device includes a main air intake duct 23 and N branch air intake ducts. The side wall of the main air intake duct 23 has N main air intake outlets and a main air intake inlet 233 connected to the main air intake duct 23. An air intake baffle 31 is rotatably installed inside the main air intake duct 23. The N main air intake outlets and N air inlets are connected one-to-one through the N branch air intake ducts.

The detection flow path is used to detect the dirt and clogging status of the filter screen corresponding to the A clothing treatment tube and the filter screen corresponding to the B clothing treatment tube. Wherein, N is a positive integer and N≥2.

[0069] Furthermore, vent 15 is located near the air outlet of garment processing drum A; vent 16 is located near the air outlet of garment processing drum B.

[0070] In addition, the air outlet of garment processing drum A is equipped with a flushing valve c, which is used to flush the filter screen at the air outlet of garment processing drum A; the air outlet of garment processing drum B is equipped with a flushing valve d, which is used to flush the filter screen at the air outlet of garment processing drum B.

[0071] <Clothing Disposal Tube>

[0072] like Figure 8a , Figure 8b , Figure 9a and Figure 9bAs shown, the garment processing drum includes a first garment processing drum and a second garment processing drum, both of which can perform washing and drying. The first and second garment processing drums are arranged side by side, with their openings facing the same side. The first garment processing drum includes a first outer drum 11 and a first inner drum 12. A first air inlet is formed on the upper side of the opening of the first outer drum 11, and a first air outlet is formed on the upper side of the side wall of the first outer drum 11. Both the first air inlet and the first air outlet are connected to the interior of the first outer drum 11. The first inner drum 12 is rotatably disposed inside the first outer drum 11. The drying airflow can enter the first outer drum 11 through the first air inlet, and then enter the first inner drum 12 to dry the load inside the first inner drum 12. Subsequently, the drying airflow is discharged through the first air outlet.

[0073] The second garment processing drum includes a second outer drum 13 and a second inner drum 14. A second air inlet is formed on the upper side of the opening of the second outer drum 13, and a second air outlet is formed on the upper side of the side wall of the second outer drum 13.

The drying airflow can enter the second outer drum 13 through the second air inlet and then enter the second inner drum 14 to dry the drying load inside the second inner drum 14. Subsequently, the drying airflow is discharged through the second air outlet. The first inner drum 12 and the second inner drum 14 have the functions of washing and shaking clothes.

[0074] <Air Inlet Device>

[0075] like Figures 1a to 5 As shown, the air intake device includes a first air distribution assembly, a first air intake duct 24, and a second air intake duct 25. The first air distribution assembly is disposed between the first outer cylinder 11 and the second outer cylinder 13 and includes a first air distribution shell. The first air distribution shell forms a main air intake duct 23. The first air intake duct 24, the main air intake duct 23, and the second air intake duct 25 are arranged vertically and connected. The end of the first air intake duct 24 away from the main air intake duct 23 is connected to the first air inlet, and the end of the second air intake duct 25 away from the main air intake duct 23 is connected to the second air inlet.

[0076] Specifically, the sidewall of the main air inlet duct 23 has a main air inlet duct inlet 233, a first main air inlet duct outlet 231, and a second main air inlet duct outlet 232 connected to the main air inlet duct 23, with the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232 arranged opposite to each other; a first branch air inlet duct 24 connects the first main air inlet duct outlet 231 and the first air inlet, and a second branch air inlet duct 25 connects the second main air inlet duct outlet 232 and the second air inlet; drying airflow It can enter the main air intake duct 23 through the main air intake inlet 233, and then enter the first outer cylinder 11 through the first main air intake outlet 231 and the first branch air intake duct 24, or enter the second outer cylinder 13 through the second main air intake outlet 232 and the second branch air intake duct 25; the first air intake and the first branch air intake duct 24 and the second air intake and the second branch air intake duct 25 are all flexible connections; the main air intake duct 23 and the first branch air intake duct 24 and the main air intake duct 23 and the second air intake duct 25 are all rigid connections.

[0077] The first air distribution assembly also includes an air inlet baffle 31, which is movably disposed within the main air inlet duct 23. The air inlet baffle 31 can open the first main air inlet duct outlet 231 and close the second main air inlet duct outlet 232, so that the drying airflow in the main air inlet duct 23 can enter the first outer cylinder 11 through the first branch air inlet duct 24; or the air inlet baffle 31 can close the first main air inlet duct outlet 231 and open the second main air inlet duct outlet 232, so that the drying airflow in the main air inlet duct 23 can enter the second outer cylinder 13 through the second branch air inlet duct 25; or the air inlet baffle 31 can open both the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232, so that a portion of the drying airflow in the main air inlet duct 23 can enter the first outer cylinder 11 through the first branch air inlet duct 24, and another portion of the drying airflow can enter the second outer cylinder 13 through the second branch air inlet duct 25.

[0078] The first air distribution shell can be integrally formed, or the first air distribution shell includes a first air distribution shell 21 and a first air distribution seat 22; the first air distribution shell 21 is disposed on the first air distribution seat 22 and forms a main air intake duct 23, the main air intake duct 23 is a cylindrical structure, the first main air intake duct outlet 231 and the second main air intake duct outlet 232 are arranged circumferentially along the main air intake duct 23, and the main air intake duct inlet 233 is located at one axial end of the main air intake duct 23; the air intake baffle 31 is an arc-shaped structure, and the air intake baffle 31 is coaxially disposed with the main air intake duct 23; the air intake baffle 31 is rotatably disposed in the main air intake duct 23, and the rotation of the air intake baffle 31 can open and close the first main air intake duct outlet 231 and the second main air intake duct outlet 232.

[0079] In other embodiments, the main air inlet duct 23 has a spherical structure and the air inlet baffle 31 has a spherical structure; this can reduce the flow resistance of the drying airflow and maximize the flow of the drying airflow to the outlet of the main air inlet duct.

[0080] The first air distribution assembly also includes a first bracket 32, which is rotatably disposed within the main air inlet duct 23. An air inlet baffle 31 is disposed on the first bracket 32. The air inlet baffle 31 can rotate synchronously with the first bracket 32. Specifically, the first bracket 32 ​​includes a first axial frame 321 and a first radial frame 322. The first axial frame 321 extends axially along the main air inlet duct 23 and is coaxially disposed with the main air inlet duct 23. The first radial frame 322 extends radially along the main air inlet duct 23, and one end of the first radial frame 322 is connected to the side wall of the first axial frame 321, while the other end of the first radial frame 322 is connected to the air inlet baffle 31. When the first axial frame 321 rotates, the first radial frame 322 rotates along with the air inlet baffle 31.

[0081] The first air distribution housing 21 has a first shaft hole formed on the side away from the first air distribution base 22, and the first shaft hole is coaxially arranged with the main air inlet duct 23; the first air distribution assembly also includes a first drive motor 33 and a first limiting frame 35; the first drive motor 33 is arranged outside the main air inlet duct 23 and the output shaft of the first drive motor 33 passes through the first shaft hole and is driven and connected to one end of the first axial frame 321; the first limiting frame 35 is arranged inside the main air inlet duct 23 and abuts against the other end of the first axial frame 321, and is used to axially limit the first axial frame 321; specifically, the first limiting frame 35 is Z-shaped.

[0082] To address the issue of incomplete sealing when the air inlet baffle 31 closes the first main air inlet outlet 231 and the second main air inlet outlet 232, this embodiment proposes that the air inlet baffle 31 can slide radially along its axis of rotation; when the air inlet baffle 31 closes the first main air inlet outlet 231 or the second main air inlet outlet 232, the air inlet baffle 31 is sealed to the side wall of the main air inlet duct 23; when the air inlet baffle 31 opens the first main air inlet outlet 231 or the second main air inlet outlet 232, the air inlet baffle 31 is spaced apart from the side wall of the main air inlet duct 23; the flow area of ​​the air inlet baffle 31 is larger than the flow area of ​​any main air inlet outlet; and the air inlet baffle 31 can completely block the first main air inlet outlet 231 or the second main air inlet outlet 232.

[0083] Furthermore, a first sealing ring is provided at the first main air intake outlet 231 and the second main air intake outlet 232. The first sealing ring is located inside the main air intake 23 and protrudes from the inner wall of the main air intake 23. The first sealing ring is made of rubber material. The air intake baffle 31 is slidably mounted on the first radial frame 322, and a first elastic member 36 is provided between the air intake baffle 31 and the first radial frame 322.

[0084] When the air inlet baffle 31 closes the first main air inlet outlet 231 or the second main air inlet outlet 232, under the action of the first elastic element 36, the air inlet baffle 31 abuts against the first sealing ring; the first main air inlet outlet 231 or the second main air inlet outlet 232 is tightly sealed, reducing air leakage, and allowing the drying airflow in the main air inlet 23 to flow smoothly to the first main air inlet outlet 231 and the second main air inlet outlet 232; when the air inlet baffle 31 opens the first main air inlet outlet 231 or the second main air inlet outlet 232, under the action of the first elastic element 36... The air inlet baffle 31 is separated from the side wall of the main air inlet duct 23, allowing the air inlet baffle 31 to rotate smoothly, reducing the friction between the air inlet baffle 31 and the inner wall of the main air inlet duct 23, reducing the torque of the first drive motor 33, and reducing the abnormal noise caused by friction; specifically, a first sliding hole is formed at one end of the first radial frame 322 near the air inlet baffle 31, and a first sliding rod is provided on one side of the air inlet baffle 31 near the first radial frame 322. The first sliding rod is slidably disposed in the first sliding hole, and a first elastic element 36 is provided between the first sliding rod and the bottom wall of the first sliding hole;

[0085] In other embodiments, along the rotation direction of the air inlet baffle 31, the radial thickness of the air inlet baffle 31 gradually decreases, and the radial thickness of the first sealing ring gradually increases.

[0086] When the air inlet baffle 31 rotates and approaches the first main air inlet outlet 231 or the second main air inlet outlet 232, the air inlet baffle 31 engages with the first sealing ring and abuts against the first sealing ring; when the air inlet baffle 31 rotates and moves away from the first main air inlet outlet 231 or the second main air inlet outlet 232, the air inlet baffle 31 separates from the first sealing ring and is spaced apart from the side wall of the main air inlet duct 23.

[0087] To address the problem that when the inlet baffle 31 closes the first main air inlet outlet 231, the drying airflow in the main air inlet 23 cannot flow smoothly to the second main air inlet outlet 232, or when the inlet baffle 31 closes the second main air inlet outlet 232, the drying airflow in the main air inlet 23 cannot flow smoothly to the first main air inlet outlet 231, this embodiment proposes that a first baffle rib be provided at the first main air inlet outlet 231 and the second main air inlet outlet 232; when the inlet baffle 31 closes the first main air inlet outlet 231 or the second main air inlet outlet 232, the first baffle rib can close the gap between the inlet baffle 31 and the side wall of the main air inlet 23, thereby blocking the airflow and reducing the flow of the drying airflow into the gap between the inlet baffle 31 and the side wall of the main air inlet 23, improving the sealing performance of the inlet baffle 31, and allowing the drying airflow to flow towards the main air inlet outlet which is in the open state, thus improving the drying efficiency.

[0088] To address the problem of low drying efficiency caused by low temperature of the drying airflow, this embodiment proposes that a heater be installed in the main air inlet duct 23; preferably, the heater is a PTC heater; during the drying stage, the PTC heater can heat the drying airflow, so that the drying airflow has a higher temperature, playing an auxiliary heating role and improving the drying efficiency.

[0090] like Figures 6a to 7 As shown, the air outlet device includes a second air distribution assembly, a first outlet air duct 44, and a second outlet air duct 45. The second air distribution assembly is disposed between the first outer cylinder 11 and the second outer cylinder 13, and includes a second air distribution shell. The second air distribution shell forms a main air outlet duct 43. The first outlet air duct 44, the main air outlet duct 43, and the second outlet air duct 45 are arranged vertically and connected. The end of the first outlet air duct 44 away from the main air outlet duct 43 is connected to the first air outlet, and the end of the second outlet air duct 45 away from the main air outlet duct 43 is connected to the second air outlet.

[0091] Specifically, the sidewall of the main air outlet duct 43 has a main air outlet, a first main air outlet duct inlet 431, and a second main air outlet duct inlet 432 connected to the main air outlet duct 43, with the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432 arranged opposite to each other; a first branch air outlet duct 44 connects the first main air outlet duct inlet 431 and the first air outlet, and a second branch air outlet duct 45 connects the second main air outlet duct inlet 432 and the second air outlet; the drying airflow inside the first outer cylinder 11 can pass through the first branch air outlet duct 44. The air outlet 44 and the first main air outlet inlet 431 enter the main air outlet 43. The drying airflow in the second outer cylinder 13 can enter the main air outlet 43 through the second branch air outlet 45 and the second main air outlet inlet 432. The drying airflow in the main air outlet 43 can be discharged through the main air outlet. The first air outlet is rigidly connected to the first branch air outlet 44 and the second air outlet and the second branch air outlet 45. The main air outlet 43 is flexiblely connected to the first branch air outlet 44 and the main air outlet 43 is flexiblely connected to the second branch air outlet 45.

[0092] The second air distribution assembly also includes an air outlet baffle 51, which is movably disposed within the main air outlet duct 43. The air outlet baffle 51 can open the first main air outlet duct inlet 431 and close the second main air outlet duct inlet 432, so that the drying airflow in the first outer cylinder 11 can enter the main air outlet duct 43 through the first outlet air outlet duct 44; or the air outlet baffle 51 can close the first main air outlet duct inlet 431 and open the second main air outlet duct inlet 432, so that the drying airflow in the second outer cylinder 13 can enter the main air outlet duct 43 through the second outlet air outlet duct 45; or the air outlet baffle 51 can open both the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432, so that the drying airflow in the first outer cylinder 11 can enter the main air outlet duct 43 through the first outlet air outlet duct 44, and the drying airflow in the second outer cylinder 13 can enter the main air outlet duct 43 through the second outlet air outlet duct 45.

[0093] The second air distribution shell can be integrally formed, or the second air distribution shell includes a second air distribution shell 41 and a second air distribution seat 42; the second air distribution shell 41 is disposed on the second air distribution seat 42 and forms a main air outlet duct 43, the main air outlet duct 43 is a cylindrical structure, the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432 are arranged circumferentially along the main air outlet duct 43, and the main air outlet duct outlet is located at one axial end of the main air outlet duct 43; the air outlet baffle 51 is an arc-shaped structure, and the air outlet baffle 51 is coaxially disposed with the main air outlet duct 43; the air outlet baffle 51 is rotatably disposed in the main air outlet duct 43, and the rotation of the air outlet baffle 51 can open and close the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432.

[0094] In other embodiments, the main air outlet 43 is a spherical structure and the air outlet baffle 51 is a spherical structure; this can reduce the flow resistance of the drying airflow and maximize the flow of the drying airflow to the main air outlet.

[0095] The second air distribution assembly also includes a second bracket 52, which is rotatably disposed within the main air outlet duct 43. An air outlet baffle 51 is disposed on the second bracket 52. The air outlet baffle 51 can rotate synchronously with the second bracket 52. Specifically, the second bracket 52 includes a second axial frame 521 and a second radial frame 522. The second axial frame 521 extends axially along the main air outlet duct 43 and is coaxially disposed with the main air outlet duct 43. The second radial frame 522 extends radially along the main air outlet duct 43, with one end connected to the side wall of the second axial frame 521 and the other end connected to the air outlet baffle 51. Rotation of the second axial frame 521 causes the second radial frame 522 to rotate along with the air outlet baffle 51.

[0096] The second air distribution housing 41 has a second shaft hole formed on the side away from the second air distribution base 42, and the second shaft hole is coaxially arranged with the main air outlet duct 43; the second air distribution assembly also includes a second drive motor 53 and a second limiting frame 55; the second drive motor 53 is located outside the main air outlet duct 43 and the output shaft of the second drive motor 53 passes through the second shaft hole and is driven to one end of the second axial frame 521; the second limiting frame 55 is located inside the main air outlet duct 43 and abuts against the other end of the second axial frame 521 to provide axial limiting for the second axial frame 521; specifically, the second limiting frame 55 is Z-shaped.

[0097] To address the issue of inadequate sealing when the air outlet baffle 51 closes the first main air outlet inlet 431 and the second main air outlet inlet 432, this embodiment proposes that the air outlet baffle 51 can slide radially along its axis of rotation; when the air outlet baffle 51 closes the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 is sealed to the side wall of the main air outlet 43; when the air outlet baffle 51 opens the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 is spaced apart from the side wall of the main air outlet 43; the flow area of ​​the air outlet baffle 51 is larger than the flow area of ​​any main air outlet inlet; and the air outlet baffle 51 can completely block the first main air outlet inlet 431 or the second main air outlet inlet 432.

[0098] Furthermore, a second sealing ring is provided at the first main air outlet inlet 431 and the second main air outlet inlet 432. The second sealing ring is located inside the main air outlet 43 and protrudes from the inner wall of the main air outlet 43. The second sealing ring is made of rubber material. The air outlet baffle 51 is slidably mounted on the second radial frame 522, and a second elastic member 56 is provided between the air outlet baffle 51 and the second radial frame 522.

[0099] When the air outlet baffle 51 closes the first main air outlet inlet 431 or the second main air outlet inlet 432, under the action of the second elastic element 56, the air outlet baffle 51 abuts against the second sealing ring; the first main air outlet inlet 431 or the second main air outlet inlet 432 is tightly sealed, reducing air leakage, allowing the drying airflow to smoothly enter the main air outlet 43 through the first main air outlet inlet 431 or the second main air outlet inlet 432; when the air outlet baffle 51 opens the first main air outlet inlet 431 or the second main air outlet inlet 432, under the action of the second elastic element 56... The air outlet baffle 51 is separated from the side wall of the main air outlet duct 43, so that the air outlet baffle 51 can rotate smoothly, reducing the friction between the air outlet baffle 51 and the inner wall of the main air outlet duct 43, reducing the torque of the second drive motor 53, and reducing the abnormal noise caused by friction. Specifically, a second sliding hole is formed at one end of the second radial frame 522 near the air outlet baffle 51, and a second sliding rod is provided on one side of the air outlet baffle 51 near the second radial frame 522. The second sliding rod is slidably disposed in the second sliding hole, and a second elastic element 56 is provided between the second sliding rod and the bottom wall of the second sliding hole.

[0100] In other embodiments, along the rotation direction of the air outlet baffle 51, the radial thickness of the air outlet baffle 51 gradually decreases, and the radial thickness of the second sealing ring gradually increases.

[0101] When the air outlet baffle 51 rotates and approaches the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 engages with the second sealing ring and abuts against the second sealing ring; when the air outlet baffle 51 rotates and moves away from the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 separates from the second sealing ring and is spaced apart from the side wall of the main air outlet 43.

[0102] In response to the problem that when the air outlet baffle 51 closes the first main air outlet inlet 431, the drying airflow in the main air outlet 43 cannot flow smoothly to the main air outlet outlet, or when the air outlet baffle 51 closes the second main air outlet inlet 432, the drying airflow in the main air outlet 43 cannot flow smoothly to the main air outlet outlet, this embodiment proposes that a second baffle rib be provided at the first main air outlet inlet 431 and the second main air outlet inlet 432.

[0103] When the air outlet baffle 51 closes the inlet 431 of the first main air outlet duct or the inlet 432 of the second main air outlet duct, the second baffle rib can close the gap between the air outlet baffle 51 and the side wall of the main air outlet duct 43; thus playing a role in blocking the wind, reducing the flow of drying air into the gap between the air outlet baffle 51 and the side wall of the main air outlet duct 43, improving the sealing performance of the air outlet baffle 51, and improving the drying efficiency.

[0104] <Wind turbine and two-phase components>

[0105] like Figure 8a and Figure 9cAs shown, the fan 61 and the two-phase assembly 62 are disposed between the first outer cylinder 11 and the second outer cylinder 13. The first air distribution shell has a main air inlet 233 on the side near the two-phase assembly 62, and the second air distribution shell has a main air outlet on the side near the fan 61. The main air outlet, the fan 61, the two-phase assembly 62 and the main air inlet 233 are connected in sequence.

[0106] Specifically, the first garment processing drum, the first outlet air duct 44, the main outlet air duct 43, the fan 61, the two-component assembly 62, the main inlet air duct 23, and the first branch inlet air duct 24 are sequentially connected to form the first drying airflow circuit. When the inlet baffle 31 opens the outlet 231 of the first main inlet air duct and the outlet baffle 51 opens the inlet 431 of the first main outlet air duct, the first drying airflow circuit is connected, and the first garment processing drum can dry. The second garment processing drum, the second outlet air duct 45, the main outlet air duct 43, the fan 61, the two-component assembly 62, the main inlet air duct 23, and the second branch inlet air duct 25 are sequentially connected to form the second drying airflow circuit. When the second main air inlet outlet 232 is opened and the air outlet baffle 51 opens the second main air outlet inlet 432, the second drying airflow circuit is connected, and the second garment processing drum can be dried; when the air inlet baffle 31 opens both the first main air inlet outlet 231 and the first main air outlet inlet 431, and the air outlet baffle 51 opens both the second main air inlet outlet 232 and the second main air outlet inlet 432, the first drying airflow circuit and the second drying airflow circuit are connected, and the first garment processing drum and the second garment processing drum can be dried simultaneously; the structure is simple, the size is small, multiple drying modes can be realized, and the weight and cost of the garment processing equipment are reduced.

[0107] Furthermore, the two-device assembly 62 includes a two-device box 621, in which two devices 622 are disposed, and the two-device box 621 forms a two-device box inlet and a two-device box outlet arranged opposite to each other. The two devices 622 are used to dehumidify and heat the drying airflow. The fan 61 forms a fan cavity, with a fan inlet formed axially and a fan outlet formed radially. The fan inlet is connected to the main air outlet, the fan outlet is connected to the two-device box inlet, and the two-device box outlet is connected to the main air inlet 233. Preferably, the air inlet device, the two-device assembly 62, the fan 61, and the air outlet device constitute an H-shaped structure.

[0108] The inlet baffle 31 and outlet baffle 51 are controlled to move, allowing any one of the garment processing drums to dry individually or multiple garment processing drums to dry simultaneously. Simultaneously, the flow rate of the drying airflow entering and exiting any garment processing drum can be adjusted. Specifically, when the first main air inlet outlet 231 is open, rotating the inlet baffle 31 adjusts the opening of the first main air inlet outlet 231, thereby adjusting the flow rate of the drying airflow entering the first garment processing drum. When the second main air inlet outlet 232 is open, rotating the inlet baffle 31 adjusts the opening of the second main air inlet outlet 232, thereby adjusting the flow rate of the drying airflow entering the second garment processing drum.

[0109] <Control Methods>
