Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and in particular relates to a clothing processing device with drying function and a drying control method. Background Technology

[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. Currently, multi-drum washing machines can only perform single-drum washing and single-drum washing and drying, with a single drying mode. To achieve multi-drum washing and drying, the required drying system structure is complex and the control process is cumbersome. Furthermore, a separate exhaust duct connected to the outside is needed to discharge the high-humidity drying airflow. This exhaust duct is only used during exhaust, occupying considerable space and having low utilization. Summary of the Invention

[0003] In view of this, the present invention provides a clothing processing device and a drying control method with a drying function to solve the problems of the existing technology, such as the inability to meet different drying needs due to the single drying mode, and the need to set up a separate exhaust duct to discharge the high humidity drying airflow, which leads to a complex drying system structure.

The outlet of the main air inlet duct and the inlet of the main air outlet duct, which are connected to the drying drum, can be controlled to open or close. The outlet of the main air inlet duct and the inlet of the main air outlet duct, which are connected to the idle drum, can be controlled to open or close. The drainage branch pipe corresponding to the idle drum can be controlled to connect or disconnect. This allows the drying drum, the corresponding branch air outlet duct, the main air duct, and the corresponding branch air inlet duct to be connected to form a circulating flow path for the drying airflow to circulate between the drying drum and the main air duct. Alternatively, the drying drum, the corresponding branch air outlet duct, the main air duct, the corresponding branch air inlet duct, the idle drum, and the corresponding drainage branch pipe can be connected to form an exhaust flow path for discharging the air from the drying drum.

[0008] Further optionally, when the main air inlet outlet and the main air outlet inlet connected to the drying cylinder are both in the open state, and the main air inlet outlet and the main air outlet inlet connected to the idle cylinder are both in the closed state, the drying cylinder and the main air duct can form the circulation path.

[0019] When the drying airflow inside the drying cylinder reaches a high temperature and high humidity state, the exhaust airflow path is connected and the drying cylinder is put into the exhaust drying mode.

[0025] When the humidity of the drying airflow is greater than the preset humidity and the temperature difference between the inlet and outlet air is greater than the preset temperature, it is determined that the drying airflow in the drying cylinder has reached a high temperature and high humidity state.

[0026] The temperature difference between the inlet and outlet of the drying cylinder is the temperature difference between the temperature of the drying airflow at the inlet and the temperature of the drying airflow at the outlet.

[0074] 9-Framework. Detailed Implementation

[0075] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0077] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0078] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. 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.

[0079] In the existing technology, multi-drum washing machines can only achieve single-drum washing and single-drum washing and drying, and the drying mode is limited. To achieve multi-drum washing and drying, the required drying system structure is complex and the control process is cumbersome. In addition, a separate exhaust duct connected to the outside is required to discharge the high humidity drying airflow. The exhaust duct is only used when exhausting air, which occupies a certain amount of space and has low utilization rate.

[0080] This invention creatively provides a clothing processing device with a drying function, comprising a main air duct, N clothing processing drums, N branch air inlets, N branch air outlets, a two-component assembly 62, and a fan 61; the main air duct includes a main air inlet duct 23 and a main air outlet duct 43, the main air inlet duct 23 having N main air inlet outlets and one main air inlet duct 233, and the main air outlet duct 43 having N main air outlet inlets and one main air outlet; each clothing processing drum has an air inlet and an air outlet; the N main air inlet outlets and N air inlets are connected one-to-one through the N branch air inlets; the N main air outlet inlets and N air outlets are connected one-to-one through the N branch air outlets; each clothing processing drum is provided with a drain branch pipe to discharge water and / or air from the corresponding clothing processing drum;

[0081] The two-phase assembly 62 is used to dehumidify and heat the drying airflow, and the fan 61 is used to provide power to the drying airflow. The two-phase assembly 62 and the fan 61 are connected to form an intermediate air duct. The main air inlet 233 and the main air outlet are connected through the intermediate air duct.

[0082] The main air inlet duct 23, the main air outlet duct 43, N garment processing drums, N branch air inlets and N branch air outlets and drainage branch pipes are designed as follows: When the garment processing equipment is running the drying program, one of the N garment processing drums is used as a drying drum and the other is used as an idle drum. The outlet of the main air inlet duct and the inlet of the main air outlet duct connected to the drying drum can be controlled to open or close. The outlet of the main air inlet duct and the inlet of the main air outlet duct connected to the idle drum can be controlled to open or close. The drainage branch pipe corresponding to the idle drum can be controlled to connect or disconnect. This allows the drying drum, the corresponding branch air outlet duct, the main air outlet duct 43, the intermediate air duct, the main air inlet duct 23 and the corresponding branch air inlet duct to be connected to form a circulation flow path for the drying airflow to circulate between the drying drum and the main air duct. Alternatively, the drying drum, the corresponding branch air outlet duct, the main air outlet duct 43, the intermediate air duct, the main air inlet duct 23 and the corresponding branch air inlet duct to be connected to form an exhaust flow path for the air in the drying drum to be discharged.

[0083] Where N is a positive integer and N≥2; the drying drum is the clothing processing drum that is in the drying stage, and the idle drum is the clothing processing drum that is not in the drying stage;

[0084] The drying airflow can circulate in the circulation path to dry the clothes inside the drying drum; or the air inside the drying drum can be discharged through the exhaust path, reducing the humidity of the drying airflow. Different flow paths can be connected according to actual needs to achieve different drying modes and meet various drying requirements. While improving the drying efficiency of the drying drum, the drainage branch pipes of the unused drums are used to discharge the high-humidity drying airflow, improving the drying effect, shortening the drying time, reducing energy consumption, and ensuring that the discharge of the high-humidity drying airflow does not affect the indoor environment, thus improving the user experience.

[0085] Furthermore, when the main air inlet outlet and the main air outlet inlet connected to the drying cylinder are both open, and the main air inlet outlet and the main air outlet inlet connected to the idle cylinder are both closed, a circulating flow path can be formed between the drying cylinder and the main air duct.

[0086] When the outlet of the main air inlet duct connected to the drying cylinder is closed and the inlet of the main air outlet duct is open, the outlet of the main air inlet duct connected to the idle cylinder is open and the inlet of the main air outlet duct is closed, and the drainage branch pipe corresponding to the idle cylinder is connected, an exhaust flow path can be formed between the drying cylinder, the main air duct, the idle cylinder and the corresponding drainage branch pipe.

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.

[0089] 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. Both the second air inlet and the second air outlet are connected to the interior of the second outer drum 13. The second inner drum 14 is rotatably disposed inside 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.

The end of the first air inlet duct 24 away from the main air inlet duct 23 is connected to the first air inlet, and the end of the second air inlet duct 25 away from the main air inlet duct 23 is connected to the second air inlet.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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 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.

[0097] 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.

[0098] To address the issue of inadequate 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 area of ​​the air inlet baffle 31 is larger than the area of ​​either main air inlet outlet 231; and the air inlet baffle 31 can completely block the first main air inlet outlet 231 or the second main air inlet outlet 232.

[0099] 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.

[0100] The air inlet baffle 31 is slidably mounted on the first radial frame 322, and a first elastic member 36 is provided between the air inlet baffle 31 and the first radial frame 322;

[0101] 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;

[0102] 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.

[0103] 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.

[0104] In response to the problem that when the air 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 air 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;

[0105] When the air inlet baffle 31 closes the outlet 231 of the first main air inlet or the outlet 232 of the second main air inlet, the first baffle rib can close the gap between the air inlet baffle 31 and the side wall of the main air inlet 23, thus blocking the airflow and reducing the flow of drying airflow into the gap between the air inlet baffle 31 and the side wall of the main air inlet 23. This improves the sealing performance of the air inlet baffle 31 and allows the drying airflow to flow towards the outlet of the main air inlet, which is in the open state, thereby improving the drying efficiency.

[0106] 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 a PTC heater; during the drying stage, the PTC heater can heat the drying airflow, giving it a higher temperature, thus playing an auxiliary heating role and improving drying efficiency.

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 air outlet duct 44, the main air outlet duct 43, and the second air outlet duct 45 are arranged vertically and connected. The end of the first air outlet duct 44 away from the main air outlet duct 43 is connected to the first air outlet, and the end of the second air outlet duct 45 away from the main air outlet duct 43 is connected to the second air outlet.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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 area of ​​the air outlet baffle 51 is larger than the 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] <Wind turbine and two-phase components>

[0124] like Figure 8a and Figure 10bAs shown, the fan 61 and the two-phase assembly 62 are arranged 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] Drainage system

[0129] When the garment processing equipment is running the drying program, the first garment processing drum is an idle drum and the second garment processing drum is a drying drum; the idle drum and the drying drum are arranged side by side, one above the other, with the idle drum having a first drain outlet and the drying drum having a second drain outlet;

[0130] like Figures 11a to 15b As shown, the garment processing equipment also includes a frame 9, with the first garment processing cylinder and the second garment processing cylinder arranged vertically within the frame 9; the garment processing equipment also includes a drainage device, which includes a drain pipe, a drain valve, and a drain box 8; the drain pipe includes a first drain branch pipe 71, a second drain branch pipe 72, and a main drain pipe 73; the drain valve includes a first drain valve 74 and a second drain valve; the drain box 8 is located between the first garment processing cylinder and the second garment processing cylinder, and the drain box 8 forms a first drain box inlet, a second drain box inlet 84, and a drain box outlet 842; the first drain outlet and the first drain box inlet are sequentially connected by the first drain branch pipe 71 and the first drain valve 74, and the first drain... Water valve 74 can be controlled to open or close, connecting or disconnecting the first drain branch pipe 71; a first drain pump is installed on the first drain branch pipe 71, under the action of the first drain pump, water in the first clothing processing drum can enter the drain box 8; a second drain branch pipe 72 and a second drain valve are sequentially connected between the second drain outlet and the second drain box inlet 84, the second drain valve can be controlled to open or close, connecting or disconnecting the second drain branch pipe 72; a second drain pump 75 is installed on the second drain branch pipe 72, under the action of the second drain pump 75, water in the second clothing processing drum can enter the drain box 8; the main drain pipe 73 connects the drain box outlet 842 and the environment where the clothing processing equipment is located.

[0131] In view of the problem of poor drainage and low drainage efficiency caused by unreasonable structural design of drainage box 8, this embodiment proposes that a first drainage box inlet is formed on the top of drainage box 8, a second drainage box inlet 84 is formed on the side wall of drainage box 8, and a drainage box outlet 842 is formed at the bottom of drainage box 8.

[0132] The drain box 8 has a first drain chamber 851 and a second drain chamber 852 inside. The bottom of the first drain chamber 851 is connected to the drain box outlet 842. The second drain chamber 852 is located outside or on one side of the first drain chamber 851. The top of the second drain chamber 852 is connected to the top of the first drain chamber 851 through a water inlet 862. A drain box inlet pipe 861 is formed at the first drain box inlet of the drain box 8. One end of the drain box inlet pipe 861 passes through the first drain chamber 851 and extends to the drain box outlet 842. The end of the drain box inlet pipe 861 near the drain box outlet 842 is connected to the first drain chamber 851. The other end of the drain box inlet pipe 861 is connected to the first drain valve 74 and the first drain branch pipe 71 in sequence. A water inlet connector 871 is formed at the second drain box inlet 84 of the drain box 8. One end of the water inlet connector 871 and the second drain chamber 852 are connected through the second drain box. The inlet 84 is connected, and the other end of the inlet connector 871 is connected to the second drain valve and the second drain branch pipe 72 in sequence. The drain box 8 has a water outlet connector 872 at the drain box outlet 842. One end of the water outlet connector 872 is connected to the drain box outlet 842, and the other end of the water outlet connector 872 is connected to the drain main pipe 73. Water or air in the idle drum can flow through the first drain branch pipe 71, the first drain valve 74, and the drain box inlet pipe 861 in sequence and enter the first drain chamber 851, and then flow through the drain box outlet 842 and the drain main pipe 73 in sequence to be discharged. Water in the drying drum can enter the second drain chamber 852 through the second drain branch pipe 72, and first accumulate in the second drain chamber 852. When it accumulates to a certain extent, it overflows through the water outlet 862 into the first drain chamber 851, and then flows through the drain box outlet 842 and the drain main pipe 73 in sequence to be discharged. This avoids the two fluids flowing together and causing mutual contamination between the two clothes processing drums, which would affect the user experience.

[0133] The structure of the drainage device of the clothing processing equipment has been simplified. The first and second clothing processing drums work together to drain water, which improves drainage efficiency. At the same time, when the drying drum is drying, the drainage branch pipe of the idle drum is used to discharge the high-humidity drying airflow from the drying drum, which improves the drying efficiency of the drying drum. The discharged high-humidity drying airflow directly enters the sewer, avoiding the problem of directly discharging into the room and affecting the indoor environment.

[0134] The drainage box 8 includes a drainage cover 82 and a drainage box body 81. The drainage cover 82 covers the drainage box body 81 and forms a cavity with the drainage box body 81. A partition 83 or a partition structure is provided inside the cavity, dividing the cavity into a first drainage cavity 851 and a second drainage cavity 852. The drainage cover 82 forms a first drainage box inlet, the bottom of the side wall of the drainage box body 81 forms a second drainage box inlet 84, and the bottom of the drainage box body 81 forms a drainage box outlet 842. Specifically, a partition 83 is provided inside the cavity or integrally formed therein. The partition 83 is annular or plate-shaped. When the partition 83 is annular, the partition 83 and a portion of the bottom wall of the drainage box body 81 form a first drainage cavity 851. A drainage cavity 851 is formed, and a water outlet 862 is formed between the top of the partition 83 and the drainage cover 82; the partition 83, the side wall of the drainage box 81, and another part of the bottom wall of the drainage box 81 form a second drainage cavity 852; the second drainage cavity 852 is located outside the first drainage cavity 851; when the partition 83 is plate-shaped, the partition 83, the bottom wall of the drainage box 81, a part of the side wall of the drainage box 81, and a part of the bottom wall of the drainage box 81 form a first drainage cavity 851, and a water outlet 862 is formed between the top of the partition 83 and the drainage cover 82; the partition 83, the other part of the side wall of the drainage box 81, and another part of the bottom wall of the drainage box 81 form a second drainage cavity 852.

[0135] The flow area of ​​the inlet connector 871 is smaller than the flow area of ​​the second drain chamber 852, the flow area of ​​the second drain chamber 852 is smaller than the flow area of ​​the water outlet 862, and the flow areas of both the first drain chamber 851 and the water outlet 862 are smaller than the flow area of ​​the outlet connector 872.

[0136] <Drying Control Methods>

[0137] like Figures 15a to 16 As shown, this embodiment also provides a drying control method for a garment processing device, wherein the garment processing device is any of the garment processing devices with drying functions described above; the garment processing device is provided with a drying program, which includes a circulating drying mode and an exhaust drying mode; when the drying drum executes the drying program, the drying control method includes:

[0138] S1. Based on the humidity of the drying airflow inside the drying drum, the temperature difference between the inlet and outlet air, and the power of the fan 61, control the drying drum to switch between circulating drying mode and exhaust drying mode.

[0139] When the drying drum operates in circulating drying mode, the drying airflow can circulate in the circulating flow path. Specifically, the drying airflow flows through the fan 61, the two devices 622, the main air inlet duct 23, the branch air inlet duct connected to the drying drum, the drying drum, the outlet air duct connected to the drying drum, and the main air outlet duct 43. When the drying drum operates in exhaust drying mode, the air inside the drying drum can be discharged through the exhaust flow path. The temperature difference between the inlet and outlet of the drying airflow inside the drying drum is the temperature difference obtained by subtracting the temperature of the drying airflow at the outlet from the temperature of the drying airflow at the inlet of the drying drum. Specifically, the drying airflow inside the drying drum enters the sewer through the outlet air duct connected to the drying drum, the main air outlet duct 43, the fan 61, the two devices 622, the main air inlet duct 23, the branch air inlet duct connected to the idle drum, the idle drum, and the first drainage branch pipe 71.

[0140] Furthermore, S1 includes:

[0141] S11. Determine whether the drying airflow in the drying drum has reached a high temperature and high humidity state based on the humidity of the drying airflow in the drying drum and the temperature difference between the inlet and outlet air, and determine whether the fan 61 has reached a high load state based on the power of the fan 61.

[0142] S12. When the drying airflow inside the drying drum reaches a high temperature and high humidity state, control the exhaust airflow path to connect and make the drying drum run in exhaust drying mode.

[0143] S13. When the fan 61 reaches a high load state, control the circulation flow path to connect and make the drying drum run in circulation drying mode.

[0144] To address the problem of inaccurate judgment regarding whether the drying airflow inside the drying drum has reached a high temperature and high humidity state, this embodiment proposes that S11 includes:

[0145] Calculate the temperature difference between the inlet and outlet air of the drying drum;

[0146] Compare the humidity of the drying airflow with the preset humidity and the temperature difference between the inlet and outlet air with the preset temperature.

[0147] When the humidity of the drying airflow is greater than the preset humidity and the temperature difference between the inlet and outlet air is greater than the preset temperature, it is determined that the drying airflow in the drying drum has reached a high temperature and high humidity state; it is necessary to discharge the high humidity drying airflow to reduce the operating load of the two devices.

[0148] To address the issue of inaccurate judgment regarding whether the fan 61 has reached a high load state, this embodiment proposes that S11 further includes:

[0149] Obtain the current power of fan 61;

[0150] Determine whether the current power has reached the preset power;

[0151] When the current power reaches the preset power, it is determined that the fan 61 has reached a high load state. At the beginning of the exhaust drying mode, the power of the fan 61 is low. As the humidity of the drying airflow in the drying cylinder decreases, the air pressure in the drying cylinder gradually decreases, forming a negative pressure, increasing the wind resistance, and the power of the fan 61 continuously increases. When the power of the fan 61 reaches the preset power, it can be determined that the high humidity gas in the drying cylinder has been discharged.

[0152] Furthermore, the control of the exhaust flow path connection in S12 includes:

[0153] Control the main air inlet outlet connected to the drying cylinder to be closed and the main air outlet inlet to be open, control the main air inlet outlet connected to the idle cylinder to be open and the main air outlet inlet to be closed, and control the first drainage branch pipe to be connected.

[0154] S13 controls the connectivity of the loop flow path, including:

[0155] The main air inlet and main air outlet connected to the drying cylinder are both opened, the main air inlet and main air outlet connected to the idle cylinder are both closed, and the first drainage branch pipe is disconnected.

[0156] In addition, drying control methods also include:

[0157] Obtain the current moisture content of the clothes inside the drying drum;

[0158] The number of times the exhaust drying mode is run is determined based on the current moisture content;

[0159] The higher the current moisture content, the more times the exhaust drying mode will run;

[0160] Specifically, in the early stage of the drying process, there is a large amount of high-humidity drying airflow inside the drying drum. This high-humidity drying airflow needs to be discharged to reduce the operating load of the two units and improve drying efficiency. For clothes of different weights, the following situations exist: when the moisture content of the clothes is high, there is more high-humidity drying airflow, and the exhaust drying mode is run more often through the drying control method; when the moisture content of the clothes is low, there is less high-humidity drying airflow, and the exhaust drying mode is run more often through the drying control method, or the exhaust drying mode is not executed.

[0161] Example 2

[0162] Unlike Example 1, when the drying drum executes the drying program, the drying control method includes:

[0163] In response to an opening command from a garment handling drum as a drying drum, the circulation path is connected and the drying drum is put into circulation drying mode;

[0164] When it is determined that the drying airflow inside the drying drum has reached a high temperature and high humidity state, the exhaust airflow path is connected and the drying drum is put into exhaust drying mode.

[0165] When it is determined that the fan 61 has reached a high load state, the circulation path is connected and the drying drum is restarted in the circulation drying mode.

[0166] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
