[0023] 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.

The outlet of the main air inlet and the inlet of the main air outlet connected to the idle drum can also be controlled to open or close. The openings of the drying drum and the idle drum can also be controlled to open or close. This allows the drying drum and the main air duct to form a circulating flow path for the drying airflow to circulate between the drying drum and the main air duct, or the drying drum, the main air duct, and the idle drum to form an exhaust flow path for discharging the air inside the drying drum, or the drying drum, the main air duct, and the idle drum to form a fresh air flow path for introducing ambient air into the drying drum.

When the drying drum and the main air duct form a circulating flow path, the drying airflow can circulate in the circulating flow path, thereby drying the clothes in the drying drum; when the drying drum, the main air duct, and the idle drum form an exhaust flow path, the air in the drying drum can be discharged through the exhaust flow path, reducing the humidity of the drying airflow; when the drying drum, the main air duct, and the idle drum form a fresh air flow path, ambient air can enter the drying drum through the fresh air flow path, improving the quality of the drying airflow; the structure of exhaust and fresh air intake in multi-drum washing machines has been optimized, improving the efficiency of exhaust and fresh air intake; According to actual needs, the corresponding flow paths can be connected to realize different drying modes and meet different drying requirements; the drying effect is improved and the drying time is shortened; the heat pump system is maximized within a limited space, and energy consumption is reduced. Where N is a positive integer and N≥2; the drying drum is the clothing processing drum in the drying stage, and the idle drum is the clothing processing drum not in the drying stage; the ambient air is the air in the environment where the clothing processing equipment is located.

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. 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.

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; 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; 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. 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.

[0032] 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; 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.

[0033] 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 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. 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.

[0037] 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.

[0038] 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. 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.

[0039] 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. 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. 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. 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. 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.

[0040] 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. 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.

[0041] <Wind turbine and two-phase components> like Figure 8a and Figure 10bAs 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. 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.

[0042] 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. The two devices 622 are used to dehumidify and heat the drying airflow. The fan 61 has 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 inlet of the two-phase box, and the outlet of the two-phase box is connected to the inlet of the main air inlet 233; preferably, the air inlet device, the two-phase assembly 62, the fan 61 and the air outlet device form an H-shaped structure.

[0043] 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.

[0044] <Drying Control Methods> like Figures 11a to 12 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, an exhaust drying mode, and a fresh air drying mode; when the drying drum executes the drying program, the drying control method includes: 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, control the drying drum to switch between circulating drying mode and exhaust drying mode. S2. Based on the surface temperature of the compressor, control the drying drum to switch between circulating drying mode and fresh air drying mode; 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 heat exchangers 622, the main air inlet duct 23, the branch air inlet duct connected to the drying drum, the drying drum, the outlet air inlet 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; specifically, the drying airflow inside the drying drum enters the environment through the outlet air inlet duct connected to the drying drum, the main air outlet duct 43, the fan 61, the two heat exchangers 622, the main air inlet duct 23, the branch air inlet duct connected to the idle drum, and the idle drum; when the drying drum operates in new... In the air drying mode, ambient air can enter the drying cylinder through the fresh air flow path; ambient air enters the drying cylinder through the idle cylinder, the outlet air duct connected to the idle cylinder, the main outlet air duct 43, the fan 61, the two heat exchangers 622, the main inlet air duct 23, and the branch inlet air duct connected to the drying cylinder, and then enters the main outlet air duct 43 through the outlet air duct connected to the drying cylinder; when the drying cylinder is operating in the circulating drying mode, exhaust drying mode, or fresh air drying mode, the fan 61 and the compressor are both in operation; the temperature difference between the inlet and outlet air of the drying airflow in the drying cylinder 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 cylinder.

[0045] To address the problem that the drying drum cannot accurately and promptly switch between circulating drying mode and exhaust drying mode, this embodiment proposes that S1 includes: 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 and the temperature difference between the inlet and outlet air, and determine whether the fan has reached a high load state based on the power of the fan. 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. S13. When the fan reaches a high load, control the circulation path to connect and make the drying drum run in circulation drying mode.

[0046] Furthermore, S11 includes: S111. Obtain the humidity of the drying airflow inside the drying drum and the temperature of the drying airflow at the air inlet and air outlet of the drying drum. S112. Calculate the temperature difference between the inlet and outlet air of the drying cylinder, and compare the humidity of the drying airflow with the preset humidity and the temperature difference between the inlet and outlet airflow with the first preset temperature. S113. 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 first preset temperature, it is determined that the drying airflow in the drying cylinder has reached a high temperature and high humidity state. In order to reduce the operating conditions of the two devices 622, it is necessary to control the drying cylinder to operate in the exhaust drying mode.

[0047] S11 also includes: Get the current power of the fan; Determine whether the current power has reached the preset power; When the current power reaches the preset power, the fan is determined to be in a high-load state. At the beginning of the exhaust drying mode, the power of the fan 61 is relatively low. As the humidity of the drying airflow in the drying drum decreases, 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 temperature and high humidity gas in the drying drum has been discharged.

[0048] Furthermore, the control of the exhaust flow path connection in S12 includes: Control the opening of the drying drum to be closed, control the opening of the idle drum to be open, control the main air inlet outlet connected to the drying drum to be closed and the main air outlet inlet to be open, and control the main air inlet outlet connected to the idle drum to be open and the main air outlet inlet to be closed. S12 controls the connectivity of the loop flow path, including: The openings of the drying drum and the idle drum are both closed. The outlet of the main air inlet and the inlet of the main air outlet connected to the drying drum are both opened. The outlet of the main air inlet and the inlet of the main air outlet connected to the idle drum are both closed.

[0049] To address the issue that the drying drum cannot accurately and promptly switch between circulating drying mode and fresh air drying mode, this embodiment proposes that S2 includes: S21. Obtain the current surface temperature of the compressor; S22. Determine whether the current surface temperature is greater than the second preset temperature or whether the current surface temperature is less than the third preset temperature; S23. When the current surface temperature is greater than the second preset temperature, control the fresh air flow path to be connected and make the drying cylinder run in fresh air drying mode. S24. When the current surface temperature is lower than the third preset temperature, control the circulation path to be connected and make the drying drum run in circulation drying mode.

[0050] Specifically, a temperature sensor is installed on the surface of the compressor. When the surface temperature of the compressor is high, the operation is unstable and the drying efficiency is low. It is necessary to control the drying drum to operate in the fresh air drying mode to reduce the surface temperature of the compressor and improve the drying efficiency. At the beginning of the fresh air drying mode, the surface temperature of the compressor is high. As ambient air is introduced, it exchanges heat with the surface of the compressor, and the surface temperature of the compressor continuously decreases. When the surface temperature of the compressor reaches the third preset temperature, it can be determined that there is no need to cool the surface of the compressor.

[0051] Furthermore, the control of the fresh air flow path connection in S23 includes: Control the opening of the drying drum to be closed, control the opening of the idle drum to be open, control the main air inlet outlet and the main air outlet inlet connected to the drying drum to be open, and control the main air inlet outlet connected to the idle drum to be closed and the main air outlet inlet to be open. S23 controls the connectivity of the circulating flow path, including: The openings of the drying drum and the idle drum are both closed. The outlet of the main air inlet and the inlet of the main air outlet connected to the drying drum are both opened. The outlet of the main air inlet and the inlet of the main air outlet connected to the idle drum are both closed.

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.
