Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment technology, and in particular to a clothing processing device. Background Technology

[0002] In the field of garment processing equipment, twin-drum garment processing equipment not only has a large capacity to meet the washing and care needs of large families, but also meets the needs of separate washing and care. After the load inside the washing drum of the twin-drum garment processing equipment is dried, odors are easily generated after a long drying time and when left to stand. In the case of high relative humidity, directly introducing fresh air to remove odors can easily increase the surface humidity of the dried load inside the washing drum, causing the load to become damp again and affecting the drying effect. Utility Model Content

[0003] The technical problem to be solved by this invention is to overcome the increased humidity on the load surface caused by the introduction of fresh air into the washing drum of the existing twin-drum clothing processing equipment, and to provide a clothing processing equipment.

[0004] The present invention aims to design a garment processing device with a double-tube design, the garment processing device comprising:

[0005] First garment processing drum, second garment processing drum;

[0006] A first air inlet duct A and a first air outlet duct B are connected to the air inlet and air outlet of the first clothing processing drum;

[0007] A second air inlet duct A and a second air outlet duct B are connected to the air inlet and air outlet of the second clothing processing drum;

[0008] The main air duct is equipped with a dehumidification module.

[0009] A bypass ventilation duct, wherein the bypass ventilation duct has a fresh air inlet connected to the external environment, and the bypass ventilation duct has a first port and a second port arranged opposite to each other along its extension direction, and a fresh air introduction device is provided in the main air duct and / or the bypass ventilation duct.

[0010] Air distribution valve A is connected to the air inlet of the first air inlet duct A, the air inlet of the second air inlet duct A, the first air outlet of the main air duct, and the first port of the bypass air duct, and is used to selectively connect or close the air inlet of the first air inlet duct A, the air inlet of the second air inlet duct A, the first air outlet of the main air duct, and the first port of the bypass air duct.

[0011] Air distribution valve B is connected to the air outlet of the first air outlet B, the air outlet of the second air outlet B, the second air outlet of the main air duct, and the second port of the bypass air duct, and is used to selectively connect or close the air outlets of the first air outlet B, the air outlets of the second air outlet B, the second air outlet of the main air duct, and the second port of the bypass air duct.

[0012] By controlling the air distribution valve A and the air distribution valve B, the fresh air entering the bypass duct from the fresh air inlet can enter the main air duct;

[0013] By controlling the air distribution valve A and the air distribution valve B, fresh air in the main air duct can enter the first air inlet duct A and / or the second air inlet duct A.

[0014] In some embodiments, the air distribution valve A includes a first valve plate and a second valve plate that are rotatably disposed. Both the first valve plate and the second valve plate are rotatable about the center of the air distribution valve A, so as to selectively connect or close the air inlet of the first air inlet duct A, the air inlet of the second air inlet duct A, the first air outlet of the main air duct, and the first port of the bypass air duct.

[0015] The air distribution valve B includes a rotatably configured third valve plate and a fourth valve plate. Both the third valve plate and the fourth valve plate can rotate around the center of the air distribution valve B to selectively connect or close the air outlet of the first air outlet duct B, the air outlet of the second air outlet duct B, the second air outlet of the main air duct, and the second port of the bypass air duct.

[0016] In some embodiments, when the fresh air humidity value is detected and during the dehumidification process of the dehumidification module, the first valve plate closes the air inlet of the first air inlet duct A, the second valve plate closes the air inlet of the second air inlet duct A, the third valve plate closes the air outlet of the first air outlet duct B, and the fourth valve plate closes the air outlet of the second air outlet duct B, so that the second air outlet of the main air duct and the second port of the bypass air duct are connected, and the first air outlet of the main air duct and the first port of the bypass air duct are connected, so that the fresh air entering the bypass air duct from the fresh air inlet can enter the main air duct.

[0017] In some embodiments, when it is determined that dehumidification of the fresh air is not required: if the first clothes handling drum needs to introduce fresh air so that the fresh air in the main air duct enters the first air inlet A, the first valve plate closes the first port of the bypass air duct, the second valve plate closes the air inlet of the second air inlet A, the third valve plate closes the second port of the bypass air duct, and the fourth valve plate closes the air outlet of the second air outlet B, so that the first air inlet A, the main air duct and the first air outlet B are connected, and the fresh air in the main air duct can enter the first air inlet A;

[0018] If the second garment processing drum needs to introduce fresh air, allowing fresh air from the main air duct to enter the second air inlet duct A, the first valve closes the first port of the bypass duct, the second valve closes the air inlet of the first air inlet duct A, the third valve closes the second port of the bypass duct, and the fourth valve closes the air outlet of the first air outlet duct B, thus connecting the second air inlet duct A, the main air duct, and the second air outlet duct B.

[0019] Fresh air from the main air duct can enter the second air intake duct A.

[0020] In some embodiments, the clothing treatment device includes a heat pump system, which includes a compressor, an evaporator, and a condenser. The evaporator and the condenser are integrated into a housing to form the dehumidification module. When it is determined that the fresh air needs to be dehumidified, the heat pump system is activated to dehumidify the fresh air using the evaporator and the condenser.

[0021] In some embodiments, the clothing processing device includes a control device, which includes a humidity detection module and a controller. The humidity detection module is used to detect the humidity value of the fresh air entering the bypass ventilation duct. The controller determines whether fresh air dehumidification is required based on the fresh air humidity value. When the controller determines that fresh air dehumidification is required, it controls the air distribution valve A, the air distribution valve B, and the dehumidification module to work together to dehumidify the fresh air.

[0022] In some embodiments, the control device includes a clothing detection module inside the bin, and the controller determines to perform fresh air intake operation control on the fresh air intake device based on the clothing detection information inside the bin by the clothing detection module within a preset time after completing the clothing processing procedure.

[0023] In some embodiments, the control device further includes a time module, and the controller is further designed to control the fresh air intake operation of the fresh air intake device based on the completion time of the clothing processing procedure provided by the time module and / or the user's work and rest schedule.

[0024] In some embodiments, the fresh air introduction device includes a fresh air fan and a fresh air valve, and the fresh air introduction operation control includes controlling the opening and closing of the fresh air valve and the rotation speed of the fresh air fan.

[0025] In some embodiments, the controller is also designed to control the frequency of the fresh air intake operation of the fresh air intake device based on the completion time of the clothing processing procedure provided by the time module.

[0026] The solution provided by this utility model has the following advantages compared with the prior art:

[0027] By using a fresh air duct assembly, fresh air can be drawn into the first and second garment processing drums of a twin-drum garment processing equipment individually, or simultaneously. During the fresh air drawing process, the coordination of the bypass duct, main duct, and dehumidifier ensures that the fresh air entering the bypass duct from the external environment first passes through the humidity detection and dehumidification in the main duct, thus maintaining the dryness of the load after drying and not affecting the original drying effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] After the load inside the washing drum of a twin-drum garment processing equipment is dried, odors can easily develop if the drying time is long and the load is left to stand. If fresh air is introduced directly to remove the odor when the relative humidity of the air is high, the surface humidity of the already dried load inside the washing drum can easily increase, causing the load to become damp again and affecting the drying effect.

[0040] Based on the above background, the following embodiments are proposed:

[0041] Example 1:

[0042] like Figure 1-5 As shown, this embodiment provides a garment processing device with a dual-tube design. The garment processing device includes:

[0043] First garment processing drum, second garment processing drum;

[0044] The first air inlet duct A1 and the first air outlet duct B2 are connected to the air inlet and air outlet of the first garment processing drum;

[0045] A second air inlet duct A3 and a second air outlet duct B4 are connected to the air inlet and air outlet of the second garment processing drum;

[0046] Main air duct 7, and dehumidification module 10 is installed inside the main air duct 7;

[0047] The bypass ventilation duct 8 has a fresh air inlet that connects to the external environment. The bypass ventilation duct 8 has a first port and a second port that are arranged opposite to each other along its extension direction. The main air duct 7 and / or the bypass ventilation duct 8 are provided with a fresh air introduction device for introducing fresh air.

[0048] The air distribution valve A5 is connected to the air inlet of the first air inlet duct A1, the air inlet of the second air inlet duct A3, the first air outlet of the main air duct 7, and the first port of the bypass air duct 8. It is used to selectively connect or close the air inlet of the first air inlet duct A1, the air inlet of the second air inlet duct A3, the first air outlet of the main air duct 7, and the first port of the bypass air duct 8.

[0049] The air distribution valve B6 is connected to the air outlet of the first air outlet B2, the air outlet of the second air outlet B4, the second air outlet of the main air outlet 7, and the second port of the bypass air outlet 8. It is used to selectively connect or close the air outlets of the first air outlet B2, the second air outlet B4, the second air outlet of the main air outlet 7, and the second port of the bypass air outlet 8.

[0050] By controlling the air distribution valves A5 and B6, the fresh air entering the bypass duct 8 from the fresh air inlet can enter the main duct 7.

[0051] By controlling the air distribution valves A5 and B6, fresh air in the main air duct 7 can enter the first air inlet duct A1 and / or the second air inlet duct A3.

[0052] In this embodiment, before introducing fresh air into the first or second clothing processing drum, if the external ambient humidity is high, such as... Figure 2As shown, by pre-controlling the air distribution valves A5 and B6, the valve plate of air distribution valve A5 closes the air inlet of the first air inlet A1 and the air inlet of the second air inlet A3, while opening the first air outlet of the main air duct 7 and the first port of the bypass air duct 8; air distribution valve B6 closes the air outlet of the first air outlet B2 and the air outlet of the second air outlet B4, while opening the second air outlet of the main air duct 7 and the second port of the bypass air duct 8. This allows the fresh air entering the bypass air duct 8 from the fresh air inlet to enter the main air duct 7. After the fresh air in the main air duct 7 is dehumidified by the dehumidification module 10, it is introduced into the first or second clothes processing drum as needed. This effectively avoids the situation where the surface humidity of the already dried load in the washing drum increases due to the direct introduction of fresh air to remove odors when the relative humidity of the air is high, causing the load to become damp again and affecting the drying effect.

[0053] Furthermore, when the first garment processing drum needs to draw in fresh air, such as Figure 3 As shown, firstly, by turning the valve plate of the air distribution valve A5, the first port of the bypass ventilation duct 8 and the air inlet of the second air inlet duct A3 are closed, while the air inlet of the first air inlet duct A1 and the first air outlet of the main air duct 7 are opened. Then, by turning the valve plate of the air distribution valve B6, the second port of the bypass ventilation duct 8 and the air outlet of the second air outlet duct B4 are closed, while the air outlet of the first air outlet duct B2 and the second air outlet of the main air duct 7 are opened. This allows the dehumidified fresh air in the main air duct 7 to enter the first clothes processing drum. This process ensures that the load in the first clothes processing drum is dry after drying and will not affect the original drying effect of the load.

[0054] When the second laundry treatment drum needs fresh air, such as Figure 4 As shown, firstly, by turning the valve plate of the air distribution valve A5, the first port of the bypass ventilation duct 8 and the air inlet of the first air inlet duct A1 are closed, while the air inlet of the second air inlet duct A3 and the first air outlet of the main air duct 7 are opened. Then, by turning the valve plate of the air distribution valve B6, the second port of the bypass ventilation duct 8 and the air outlet of the first air outlet duct B2 are closed, while the air outlet of the second air outlet duct B4 and the second air outlet of the main air duct 7 are opened. This allows the dehumidified fresh air in the main air duct 7 to enter the second clothes processing drum. This process ensures that the load in the second clothes processing drum is dry after drying and will not affect the original drying effect of the load.

[0055] When both the first and second garment processing drums require fresh air intake, such as Figure 5As shown, firstly, the first port of the bypass ventilation duct 8 is closed by the deflector valve A5, while simultaneously opening the air inlets of the first air inlet duct A1, the second air inlet duct A3, and the first air outlet of the main air duct 7. Then, the second port of the bypass ventilation duct 8 is closed by the deflector valve B6, while simultaneously opening the air outlets of the first air outlet duct B2, the second air outlet duct B4, and the second air outlet of the main air duct 7. This allows dehumidified fresh air from the main air duct 7 to enter the first and second garment processing drums. This process ensures that the loads in the first and second garment processing drums remain dry after drying, without affecting the original drying effect.

[0056] Optionally, in one implementation of this embodiment, such as Figure 2-5 As shown,

[0057] The air distribution valve A5 includes a first valve plate 501 and a second valve plate 502 that are rotatably configured. Both the first valve plate 501 and the second valve plate 502 can rotate around the center of the air distribution valve A5 to selectively connect or close the air inlet of the first air inlet A1, the air inlet of the second air inlet A3, the first air outlet of the main air duct 7, and the first port of the bypass air duct 8.

[0058] The air distribution valve B6 includes a third valve plate 601 and a fourth valve plate 602 that are rotatably configured. Both the third valve plate 601 and the fourth valve plate 602 can rotate around the center of the air distribution valve B6 to selectively connect or close the air outlet of the first air outlet B2, the air outlet of the second air outlet B4, the second air outlet of the main air duct 7, and the second port of the bypass air duct 8.

[0059] Air distribution valves A5 and B6 have the same structure, both consisting of a valve body and two internal valve plates. The valve plates are electrically controlled and rotate around the center of the air distribution valve to open or close the corresponding air outlets and ports.

[0060] Optionally, in one implementation of this embodiment, such as Figure 2 As shown,

[0061] When the humidity detection module 9 detects the humidity value of the fresh air entering the bypass ventilation duct 8 and during the dehumidification process of the dehumidification module 10 on the fresh air, the first valve plate 501 closes the air inlet of the first air inlet duct A1, the second valve plate 502 closes the air inlet of the second air inlet duct A3, the third valve plate 601 closes the air outlet of the first air outlet duct B2, and the fourth valve plate 602 closes the air outlet of the second air outlet duct B4. This makes the second air outlet of the main air duct 7 connected to the second port of the bypass ventilation duct 8, and the first air outlet of the main air duct 7 connected to the first port of the bypass ventilation duct 8, so that the fresh air entering the bypass ventilation duct 8 from the fresh air inlet can enter the main air duct 7.

[0062] In this embodiment, before introducing fresh air into the first or second clothing processing drum, the first air inlet of the first air inlet duct A1 is closed by the first valve plate 501, the second air inlet of the second air inlet duct A3 is closed by the second valve plate 502, the third air outlet of the first air outlet duct B2 is closed by the third valve plate 601, and the fourth air outlet of the second air outlet duct B4 is closed by the fourth valve plate 602. This allows for connection between the second air outlet of the main air duct 7 and the second port of the bypass air duct 8, and between the first air outlet of the main air duct 7 and the first port of the bypass air duct 8. Fresh air entering the bypass air duct 8 through the fresh air inlet can then enter the main air duct 7, while fresh air cannot enter the first air inlet of the first air inlet duct A1 or the second air inlet duct. The A3 air inlet prevents excessively humid fresh air from directly entering the first air inlet (A1) and the second air inlet (A3). This design allows the humidity detection module 9 in the main air duct 7 to detect the humidity of the introduced fresh air. If the humidity of the fresh air is significantly higher than the preset value, it indicates that the ambient humidity is too high and it is not suitable to directly introduce fresh air. In this case, the dehumidification module 10 dehumidifies the fresh air in the main air duct 7. After dehumidification, the dehumidified fresh air in the main air duct 7 is then introduced into the corresponding clothes processing drum. This process ensures that the load remains dry after drying and does not affect the original drying effect of the load.

[0063] Optionally, in one implementation of this embodiment, such as Figure 3 , 4 As shown,

[0064] When it is determined that dehumidification of the fresh air is not required:

[0065] If the first clothing processing drum needs to introduce fresh air, the first valve 501 closes the first port of the bypass ventilation duct 8, the second valve 502 closes the air inlet of the second air inlet duct A3, the third valve 601 closes the second port of the bypass ventilation duct 8, and the fourth valve 602 closes the air outlet of the second air outlet duct B4, so that the first air inlet duct A1, the main air duct 7 and the first air outlet duct B2 are connected, and the fresh air in the main air duct 7 can enter the first air inlet duct A1;

[0066] If the second clothing processing drum needs to introduce fresh air, the first valve 501 closes the first port of the bypass ventilation duct 8, the second valve 502 closes the air inlet of the first air inlet duct A1, the third valve 601 closes the second port of the bypass ventilation duct 8, and the fourth valve 602 closes the air outlet of the first air outlet duct B2, so that the second air inlet duct A3, the main air duct 7 and the second air outlet duct B4 are connected, and the fresh air in the main air duct 7 can enter the second air inlet duct A3.

[0067] In this embodiment, when the first clothing processing drum needs to draw in fresh air, such as Figure 3As shown, fresh air enters the first air inlet duct A1 from the main air duct 7. Specifically, the first valve 501 closes the first port of the bypass duct 8, the second valve 502 closes the air inlet of the second air inlet duct A3, the third valve 601 closes the second port of the bypass duct 8, and the fourth valve 602 closes the air outlet of the second air outlet duct B4, thus connecting the first air inlet duct A1, the main air duct 7, and the first air outlet duct B2. This allows the dehumidified fresh air in the main air duct 7 to enter the first clothes processing drum. This process ensures that the load in the first clothes processing drum remains dry after drying and does not affect the original drying effect of the load.

[0068] When the second laundry treatment drum needs fresh air, such as Figure 4 As shown, fresh air enters the second air inlet duct A3 from the main air duct 7. Specifically, the first valve 501 closes the first port of the bypass duct 8, the second valve 502 closes the air inlet of the first air inlet duct A1, the third valve 601 closes the second port of the bypass duct 8, and the fourth valve 602 closes the air outlet of the first air outlet duct B2, thus connecting the second air inlet duct A3, the main air duct 7, and the second air outlet duct B4. This allows the dehumidified fresh air in the main air duct 7 to enter the second clothes processing drum. This process ensures that the load in the first clothes processing drum remains dry after drying and does not affect the original drying effect of the load.

[0069] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0070] The clothing processing equipment includes a heat pump system, which includes a compressor, an evaporator, and a condenser. The evaporator and condenser are integrated into a single unit to form a dehumidification module 10. When it is determined that fresh air needs to be dehumidified, the heat pump system is activated to dehumidify the fresh air using the evaporator and condenser.

[0071] When it is necessary to dehumidify the fresh air in the main air duct 7, the compressor and condenser are started, so that the fresh air in the main air duct 7 is condensed by the condenser, and the water droplets are discharged, thereby reducing the humidity of the fresh air in the main air duct 7.

[0072] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0073] The clothing processing equipment includes control equipment, which includes a humidity detection module 9 and a controller. The humidity detection module 9 is used to detect the humidity value of the fresh air entering the bypass ventilation duct 8. The controller determines whether fresh air dehumidification is required based on the fresh air humidity value. When the controller determines that fresh air dehumidification is required, it controls the air distribution valve A, air distribution valve B, and dehumidification module 10 to work together to dehumidify the fresh air.

[0074] In this embodiment, the humidity detection module 9 can be a humidity sensor. The humidity sensor can acquire the humidity value of the fresh air in the main air duct 7. By comparing it with a preset humidity value, the relative humidity of the fresh air can be determined, thus accurately determining whether the fresh air can be directly introduced into the clothes drying drum to avoid affecting the drying effect. When the acquired humidity value is greater than or equal to the preset humidity value, the fresh air is pre-dehumidified before being introduced into the corresponding clothes drying drum. When the acquired humidity value is less than the preset humidity value, fresh air can be directly introduced into the corresponding clothes drying drum from the bypass channel 8. Figure 6 As shown, at this time, by turning the valve plate of the air distribution valve A5, the first air outlet of the main air duct 7 is closed, while the air inlets of the first air inlet duct A1, the second air inlet duct A3, and the first port of the bypass air duct 8 are opened. By turning the valve plate of the air distribution valve B6, the second air outlet of the main air duct 7 is closed, while the air outlets of the first air outlet duct B2, the second air outlet duct B4, and the second port of the bypass air duct 8 are opened. This allows the fresh air entering the bypass air duct 8 from the fresh air inlet to directly enter the first and second garment processing drums to draw in fresh air. By turning the valve plates of the air distribution valves A5 and B6, fresh air can also be directly introduced into the garment processing drum that needs fresh air, and the turning principle is the same as described above.

[0075] Alternatively, in one implementation of this embodiment,

[0076] The control device includes a clothing detection module inside the bin. The controller determines the fresh air intake operation control of the fresh air intake device based on the clothing detection information inside the bin within a preset time after the clothing processing procedure is completed by the clothing detection module.

[0077] In this embodiment, if the clothes are removed within the preset time of completing the clothes processing procedure, there is no need to introduce fresh air into the clothes. If the clothes are not removed within the preset time of completing the clothes processing procedure, it proves that the clothes have been in the clothes processing drum for a long time without being taken out, which may produce odors. In this case, fresh air needs to be introduced into the clothes to remove the odors from the clothes.

[0078] In response to the fresh air intake start command, the controller controls the first air intake duct A1, the first air outlet duct B2, the second air intake duct A3 and the second air outlet duct B4 to all close, and controls the fresh air to enter the bypass ventilation duct 8 through the air outlet and then enter the main air duct 7.

[0079] The dehumidifier is controlled to obtain the humidity value s of the fresh air in the main air duct 7, and the humidity value s is compared with the preset humidity value s1, where s1 is any value between 50% and 70%.

[0080] If s < s1, then fresh air is directly introduced into the first air intake duct A1 and / or the second air intake duct A3 to complete a single fresh air intake.

[0081] If s≥s1, the dehumidifier is controlled to dehumidify the fresh air in the main air duct 7. After dehumidification, the dehumidified fresh air is introduced into the first air inlet duct A1 and / or the second air inlet duct A3 to complete a single fresh air intake.

[0082] In this embodiment, the fresh air control method can either draw fresh air into the first and second clothing processing tubes of the clothing processing equipment individually, or draw fresh air into the first and second clothing processing tubes simultaneously.

[0083] The controller responds to the fresh air intake start command, which can be to intake fresh air into the first clothing handling drum alone, or into the second clothing handling drum alone, or to intake fresh air into the first and second clothing handling drums simultaneously.

[0084] The following example illustrates how the fresh air intake command simultaneously introduces fresh air into both the first and second garment processing drums:

[0085] In response to the fresh air intake start command, the controller controls the first air intake duct A1, the first air outlet duct B2, the second air intake duct A3 and the second air outlet duct B4 to close, and controls the fresh air intake device, i.e. the fan, to bring fresh air from the fresh air inlet into the bypass ventilation duct 8, and then into the main air duct 7 through the bypass ventilation duct 8.

[0086] The humidity detection module 9 acquires the humidity value s of the fresh air in the main air duct 7, and compares the humidity value s with the preset humidity value s1. The humidity detection module 9 can be a humidity sensor.

[0087] If s < s1, it proves that the ambient humidity is relatively low at this time. Figure 6 As shown, by controlling the rotation of the air distribution valve A5, the first air outlet of the main air duct 7 is closed, while the air inlets of the first air inlet A1, the second air inlet A3, and the first port of the bypass air duct 8 are opened. By controlling the rotation of the air distribution valve B6, the second air outlet of the main air duct 7 is closed, while the air outlets of the first air outlet B2, the second air outlet B4, and the second port of the bypass air duct 8 are opened. This allows the fresh air entering the bypass air duct 8 from the fresh air inlet to directly enter the first and second clothing processing cylinders to draw in fresh air, completing a single fresh air intake.

[0088] If s ≥ s1, it indicates that the ambient humidity is high and it is not suitable to directly introduce fresh air. In this case, the dehumidification module 10 is activated to dehumidify the fresh air in the main air duct 7. After dehumidification, if... Figure 5As shown, by controlling the rotation of the air distribution valve A5, the first port of the bypass ventilation duct 8 is closed, while the air inlets of the first air inlet duct A1, the second air inlet duct A3, and the first air outlet of the main air duct 7 are opened. Similarly, by controlling the rotation of the air distribution valve B6, the second port of the bypass ventilation duct 8 is closed, while the air outlets of the first air outlet duct B2, the second air outlet duct B4, and the second air outlet of the main air duct 7 are opened. This allows dehumidified fresh air from the main air duct 7 to enter the first and second garment processing drums, drawing in fresh air. This process ensures that the loads in the first and second garment processing drums remain dry after drying, without affecting the original drying effect.

[0089] Alternatively, in one implementation of this embodiment,

[0090] The control device also includes a time module, and the controller is further designed to control the fresh air intake operation of the fresh air intake device based on the completion time of the clothing processing program provided by the time module and / or the user's work and rest schedule.

[0091] In this embodiment, the setting of the time module facilitates the fresh air introduction device to introduce fresh air into the clothing processing drum according to a predetermined program.

[0092] In this embodiment, the method of directly introducing fresh air into the first clothing processing tube can be achieved by directly opening the air inlet of the first air inlet duct A1 and the air outlet of the first air outlet duct B2. At this time, the air duct of the first clothing processing tube is in a fully open state, which is suitable for directly introducing fresh air. Similarly, the method of directly introducing fresh air into the second clothing processing tube can be achieved by directly opening the air inlet of the second air inlet duct A3 and the air outlet of the second air outlet duct B4. At this time, the air duct of the second clothing processing tube is in a fully open state, which is suitable for directly introducing fresh air.

[0093] After being dehumidified by the main air duct 7, the fresh air is introduced into the first clothing processing drum. The first air inlet A1 is opened first to allow fresh air to enter the first air inlet A1. The first air outlet B2 is closed for 10 seconds and then opened again to allow the dehumidified fresh air to circulate fully in the first clothing processing drum, thereby improving the effect of introducing fresh air. For example, it can more effectively remove odors. The first air outlet B2 is opened for 2 minutes to avoid introducing undehumidified fresh air for too long.

[0094] Alternatively, in one implementation of this embodiment,

[0095] The fresh air introduction device includes a fresh air fan and a fresh air valve. The fresh air introduction operation control includes controlling the opening and closing of the fresh air valve and the speed of the fresh air fan.

[0096] Controlling the opening and closing of the fresh air valve facilitates the control of the fresh air flow direction, and controlling the speed of the fresh air fan facilitates the control of the fresh air volume.

[0097] Alternatively, in one implementation of this embodiment,

[0098] The controller is also designed to control the frequency of fresh air intake operation of the fresh air intake device based on the completion time of the clothing processing program provided by the time module.

[0099] In this embodiment, after time T, the number of times fresh air is drawn in, n, is obtained, and then compared with the preset number of times fresh air is drawn in, n1.

[0100] If n≥n1, the controller responds to the fresh air intake termination command;

[0101] If n < n1, the controller continues to respond to the fresh air intake start command.

[0102] For example, if n1 = 3 and T = 3h, that is, after 3 hours, if the number of times fresh air is introduced is n≥3, then the controller will respond to the fresh air introduction end command. If n<n1, then the controller will continue to respond to the fresh air introduction start command. This ensures that there are enough fresh air introduction times and can also achieve automatic end of fresh air introduction.

[0103] In summary, the ingenious design of garment processing equipment lies in:

[0104] First, fresh air can be drawn into the first and second garment processing drums of the twin-drum garment processing equipment individually, or fresh air can be drawn into the first and second garment processing drums simultaneously. During the fresh air drawing process, through the cooperation of the bypass ventilation duct, the main air duct, and the dehumidifier, the fresh air entering the bypass ventilation duct from the external environment can first pass through the humidity detection and dehumidification of the main air duct, thereby keeping the load dry after drying and not affecting the original drying effect of the load.

[0105] Secondly, the design uses an air inlet duct that opens and an air outlet duct that closes for a certain period of time before opening again. This allows the dehumidified fresh air to circulate fully within the clothes processing drum, thereby improving the fresh air intake effect and more effectively removing odors. This air intake method is also suitable for circulating the dehumidified fresh air from the main air duct into the clothes processing drum. The opening time of the air outlet duct should be controlled to avoid introducing undehumidified fresh air for too long.
