[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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, which cannot meet different drying needs; to achieve multi-drum drying, the control process is complicated and the drying sequence design is unreasonable, resulting in low drying efficiency and long drying time.

[0065] This invention creatively provides a drying control method for a garment processing device. The garment processing device includes a main air duct, N garment processing drums, N branch air inlets, and N branch air outlets. The main air duct has N main air outlets and N main air inlets. Each garment processing drum has an air inlet and an air outlet. One end of each of the N branch air inlets is connected to one of the N main air outlets, and the other end of each branch air inlet is connected to one of the N air inlets. One end of each of the N branch air outlets is connected to one of the N main air inlets, and the other end of each branch air outlet is connected to one of the N air outlets. The system is interconnected, forming a drying airflow loop between each garment processing drum and the main air duct. Each main air duct outlet and inlet can be controlled to open or close. The drying control method includes obtaining the load weight and moisture content of each garment processing drum before drying, estimating the required drying time based on the load weight and moisture content of each drum, calculating ts, comparing ts with t0, and controlling the connection of the corresponding drying airflow loop based on the comparison result of ts and t0. Here, N is a positive integer and N≥2, ts is the sum of the required drying times for N garment processing drums, and t0 is the preset time.

[0066] The drying control process has been simplified, the drying sequence in multi-drum drying has been optimized, and the clothes handling drum and drying airflow have been fully utilized to achieve high-efficiency heat exchange between the load and the drying airflow. This has improved drying efficiency and drying control accuracy, shortened the drying time, and solved the problems of cumbersome control process and unreasonable drying sequence design in existing multi-drum washing machines, which resulted in low drying efficiency and long drying time.

[0067] Furthermore, the main air duct includes a main air inlet duct and a main air outlet duct. The main air inlet duct has N main air inlet duct outlets and one main air inlet duct inlet, with the main air inlet duct outlet being the main air inlet duct inlet. The main air outlet duct has N main air outlet duct inlets and one main air outlet duct outlet, with the main air outlet duct inlet being the main air inlet duct inlet.

[0068] The garment processing equipment also includes a two-unit assembly and a fan. The fan is used to provide power to the drying airflow, and the two-unit assembly and the fan are connected to form an intermediate air duct. The main air inlet and the main air outlet are connected through the intermediate air duct, so that the main air inlet, intermediate air duct, main air outlet and the corresponding garment processing drum, branch air inlet and branch air outlet constitute a drying airflow loop.

[0069] <Clothing Disposal Tube>

[0070] like Figure 8a , Figure 8b , Figure 9a and Figure 9bAs shown, N garment processing drums include 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.

[0071] 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.

[0072] <Air Inlet Device>

[0073] like Figures 1a to 5 As shown, the garment processing equipment includes an air inlet device, which includes a first air distribution assembly, a first air inlet duct 24, and a second air inlet 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 inlet duct 23. The first air inlet duct 24, the main air inlet duct 23, and the second air inlet duct 25 are arranged vertically and connected. 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.

[0074] 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; the drying airflow can pass through the main air inlet duct. The air inlet 233 enters the main air inlet duct 23. The drying airflow in the main air inlet duct 23 can enter the first outer cylinder 11 through the first main air inlet outlet 231 and the first branch air inlet duct 24, or enter the second outer cylinder 13 through the second main air inlet outlet 232 and the second branch air inlet duct 25. The first air inlet and the first branch air inlet duct 24, as well as the second air inlet and the second branch air inlet duct 25, are all flexibly connected. The main air inlet duct 23 and the first branch air inlet duct 24, as well as the main air inlet duct 23 and the second air inlet duct 25, are all rigidly connected.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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;

[0083] 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;

[0084] 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.

[0085] 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.

[0086] 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;

[0087] 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.

[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 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.

[0089] <Air outlet device>

[0090] like Figures 6a to 7 As shown, the garment processing equipment includes an air outlet device, which includes a second air distribution assembly, a first air outlet duct 44, and a second air outlet 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 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.

[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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] <Wind turbine and two-phase components>

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.

[0108] 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 has two device box inlets and two device box outlets disposed opposite to each other.
