[0059] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] After the load in the washing drum of a double-drum clothing processing device is dried, it is easy to produce odor if the drying time is long or if it is left standing. When the relative humidity of the air is high, directly introducing fresh air to remove the odor can easily increase the humidity on the surface of the dried load in the washing drum, causing the load to become wet again, affecting the drying effect.

[0061] Based on the above background, the following embodiments are proposed:

[0062] Embodiment 1:

[0063] like Figure 1 , 2 8, a fresh air control method is provided, which is applied to a double-drum laundry processing device.

[0064] The double-drum laundry processing device comprises a first laundry processing drum and a second laundry processing drum;

[0065] a first air duct connected to the first laundry processing tub;

[0066] a second air duct connected to the second laundry processing tub;

[0067] A main air duct 7, wherein a dehumidification module 10 is arranged in the main air duct 7;

[0068] A bypass air duct 8, wherein the bypass air duct 8 is connected to the external environment, the main air duct 7, the first air duct and the second air duct, and a fresh air introduction device is provided in the main air duct 7 and / or the bypass air duct 8;

[0069] a first air distribution valve 5 and a second air distribution valve 6, wherein the first air distribution valve 5 is used to selectively connect or close the first air inlet section 1 of the first air duct, the second air inlet section 3 of the second air duct, the main air duct 7, and the bypass air duct 8, and the second air distribution valve 6 is used to selectively connect or close the first air outlet section 2 of the first air duct, the second air outlet section 4 of the second air duct, the main air duct 7, and the bypass air duct 8;

[0070] The method comprises:

[0071] When the main air duct 7 and the bypass air duct 8 are connected, the fresh air humidity value s is obtained, and the humidity value s is compared with the preset humidity value s1.

[0072] If s<s1, the first air distribution valve 5 and the second air distribution valve 6 are controlled to connect the main air duct 7 with the target air duct, and the target air duct is the first air duct and / or the second air duct;

[0073] If s≥s1, the dehumidification module 10 is controlled to dehumidify the fresh air in the main air duct 7 until s<s1.

[0074] Specifically, the method further includes connecting the main air duct 7 and the bypass air duct 8 in the following manner:

[0075] Control the first air distribution valve 5 to close the connection between the first air inlet section 1 and the main air duct 7 and the bypass air duct 8, close the connection between the second air inlet section 3 and the main air duct 7 and the bypass air duct 8, and connect the main air duct 7 and the bypass air duct 8;

[0076] The second air distribution valve 6 is controlled to close the connection between the first air outlet section 2 and the main air duct 7 and the bypass air duct 8, and the connection between the second air outlet section 4 and the main air duct 7 and the bypass air duct 8 is closed, so as to connect the main air duct 7 and the bypass air duct 8.

[0077] In this embodiment, a control device is provided on a double-drum clothing processing device, and the control device includes a controller and a clothing detection module in the drum. The controller determines to control the fresh air introduction operation of the fresh air introduction device based on the clothing detection information in the drum within a preset time period after the clothing processing program is completed by the clothing detection module in the drum.

[0078] If the clothes are taken out within the preset time of completing the clothes treatment program, there is no need to introduce fresh air to the clothes. If the clothes are not taken out within the preset time of completing the clothes treatment program, it proves that the dried clothes have been in the clothes treatment drum for a long time without being taken out, and there is a possibility of odor. Fresh air needs to be introduced to the clothes to remove the odor of the dried clothes.

[0079] like Figure 8 As shown, the controller responds to the fresh air start instruction,

[0080] Control the first air distribution valve 5 to close the first air inlet section 1 of the first air duct, the second air inlet section 3 of the second air duct, the main air duct 7 and the bypass air duct 8, and connect the main air duct 7 and the bypass air duct 8;

[0081] Control the second air distribution valve 6 to close the first air outlet section 2 of the first air duct, the second air outlet section 4 of the second air duct, the main air duct 7 and the bypass air duct 8, and connect the main air duct 7 and the bypass air duct 8;

[0082] In this way, conduction between the main air duct 7 and the bypass air duct 8 is achieved, the connection between the first air duct and the first clothing processing drum is closed, and the connection between the second air duct and the second clothing processing drum is closed, so that the introduced fresh air circulates in the main air duct 7 and the bypass air duct 8, and temporarily does not enter the first clothing processing drum and the second clothing processing drum.

[0083] The dehumidification control module 10 obtains the fresh air humidity value s in the main air duct 7, and compares the humidity value s with the preset humidity value s1.

[0084] If s<s1, the first air distribution valve 5 is controlled to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange;

[0085] If s≥s1, the dehumidification module 10 is controlled to dehumidify the fresh air in the main air duct 7. After the dehumidification is completed, when s<s1, a single fresh air exchange is completed.

[0086] Wherein, s1 is any value between 50% and 70%, and the humidity detection module 9 is controlled to obtain the fresh air humidity value s in the main air duct 7, and the humidity value s is compared with the preset humidity value s1. The humidity detection module 9 may be a humidity sensor.

[0087] If s<s1, it means that the external humidity is low. Figure 7 As shown, the first air division valve 5 and the second air division valve 6 are controlled to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange, that is, according to the need of introducing fresh air, fresh air is introduced into the first clothing processing drum and / or the second clothing processing drum by controlling the first air division valve 5 and the second air division valve 6. For example, when fresh air needs to be introduced into the first clothing processing drum and fresh air does not need to be introduced into the second clothing processing drum, the first air division valve 5 and the second air division valve 6 can be controlled to only connect the main air duct 7 and the first air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct, and the fresh air enters the first clothing processing drum from the first air duct to exchange the clothes in the first clothing processing drum with fresh air, thereby completing a single fresh air exchange.

[0088] If s≥s1, it proves that the humidity of the external environment is relatively high at this time, and it is not suitable to directly introduce fresh air. In this case, the dehumidification module 10 is controlled to start working, and the fresh air in the main air duct 7 is dehumidified. After the dehumidification is completed, the first air branch valve 5 and the second air branch valve 6 are controlled in the same manner as above to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange;

[0089] This process can ensure that the loads in the first laundry processing drum and the second laundry processing drum are dry after drying, and will not affect the original drying effect of the loads.

[0090] Optionally, in an implementation of this embodiment,

[0091] Controlling the first air distribution valve 5 and the second air distribution valve 6 to connect the main air duct 7 and the target air duct includes:

[0092] When the fresh air introduction device is controlled to work,

[0093] The first air distribution valve 5 is controlled to be in a state of opening the first air inlet section 1 and the second air distribution valve 6 is controlled to be in a state of closing the first air outlet section 2, and after a duration of t1, the second air distribution valve 6 is controlled to be in a state of opening the first air outlet section 2 and a duration of t2;

[0094] And / or, control the first air distribution valve 5 to be in a state of opening the second air inlet section 3 and control the second air distribution valve 6 to be in a state of closing the second air outlet section 4, and after continuing for a period of t3, control the second air distribution valve 6 to be in a state of opening the second air outlet section 4 and continue for a period of t4.

[0095] Preferably, 5s≤t1≤20s, 5s≤t3≤20s; 1min≤t2≤3min, 1min≤t4≤3min.

[0096] In this embodiment, the control device further includes a duration module, and the controller is further designed to control the fresh air introduction device to introduce fresh air according to the completion duration of the clothing treatment program provided by the duration module and / or the user's work and rest duration. The provision of the duration module facilitates the fresh air introduction device to introduce fresh air into the clothing treatment drum according to a predetermined program.

[0097] Taking the fresh air introduction device that introduces the fresh air in the main air duct 7 into the first air duct as an example for explanation, the fresh air introduction device that introduces the fresh air in the main air duct 7 into the first air duct is to introduce the fresh air in the main air duct 7 into the first clothing processing drum through the first air duct. At this time, the first air duct connected to the first clothing processing drum is in a fully open state, which is suitable for directly introducing fresh air. When the fresh air dehumidified by the main air duct 7 is introduced into the first clothing processing drum, the first air distribution valve 5 is first controlled to open the first air inlet section 1, so that the fresh air enters the first air inlet section 1, and at the same time The second air distribution valve 6 is controlled to close the first air outlet section 2, and this state lasts for 10s. Then the second air distribution valve 6 is controlled to open the first air outlet section 2. This control method allows the dehumidified fresh air to fully flow in the first clothing processing drum, thereby improving the effect of introducing fresh air. For example, it can more effectively remove odors. The second air distribution valve 6 is controlled to open the first air outlet section 2 for 2 minutes to complete a single fresh air exchange in the first clothing processing drum. This control method can avoid the second air distribution valve 6 opening the first air outlet section 2 for too long and introducing fresh air that has not been dehumidified.

[0098] Optionally, in an implementation of this embodiment,

[0099] Fresh air control methods also include:

[0100] After a time T has passed since the fresh air start instruction was initiated, the number of fresh air changes n is obtained, and the number of fresh air changes n is compared with the preset number of fresh air changes n1.

[0101] If n≥n1, the fresh air exchange ends;

[0102] If n<n1, continue to change the fresh air;

[0103] Among them, each time the first air distribution valve 5 and the second air distribution valve 6 are controlled to connect the main air duct 7 and the target air duct and maintain the setting time is one fresh air exchange number.

[0104] In this embodiment, the controller is also designed to control the frequency of the fresh air introducing operation of the fresh air introducing device according to the completion time of the clothing treatment program provided by the time module.

[0105] For example, n1=3, T=3h, that is, after the start of fresh air introduction, after 3 hours, the number of fresh air introduction times n≥3, the controller responds to the fresh air introduction end instruction. If n<n1, the controller continues to respond to the fresh air introduction start instruction, which can not only ensure a sufficient number of fresh air introduction times, but also automatically end the fresh air introduction.

[0106] If the target air duct is the first air duct or the second air duct, the main air duct 7 is connected to the target air duct and t1+t2 or t3+t4 is maintained as one fresh air exchange;

[0107] If the target air duct is the first air duct and the second air duct, the main air duct 7 is connected to the target air duct, and the first air duct is maintained at t1+t2, and the second air duct is maintained at t3+t4 as one fresh air exchange.

[0108] Optionally, in an implementation of this embodiment, as Figure 2-7 As shown,

[0109] The first air distribution valve 5 includes a first valve plate 501 and a second valve plate 502 which are rotatably arranged. The first valve plate 501 and the second valve plate 502 can both rotate with the center of the first air distribution valve 5 as the rotation center, so as to selectively connect or close the first air inlet section 1, the second air inlet section 3, the main air duct 7 and the bypass air duct 8;

[0110] The second air distribution valve 6 includes a third valve disc 601 and a fourth valve disc 602 which are rotatably arranged. The third valve disc 601 and the fourth valve disc 602 can rotate with the center of the second air distribution valve 6 as the rotation center, so as to selectively connect or close the first air outlet section 2, the second air outlet section 4, the main air duct 7 and the bypass air duct 8.

[0114] like Figure 3 As shown, the third valve plate 601 is controlled to close the first air outlet section 2 , and the fourth valve plate 602 is controlled to close the second air outlet section 4 .

[0115] In this embodiment, the first air dividing valve 5 and the second air dividing valve 6 have the same structure, both consisting of a valve housing and two internal valve plates. The valve plates are electrically controlled valve plates, and the valve plates rotate around the center of the air dividing valve to open or close the corresponding air sections and ports.

[0116] Specifically, Figure 3As shown, when the humidity detection module 9 detects the humidity value of the fresh air entering the bypass air duct 8 and the dehumidification module 10 is performing dehumidification processing on the fresh air, the first valve plate 501 closes the first air inlet section 1, the second valve plate 502 closes the second air inlet section 3, the third valve plate 601 closes the first air outlet section 2, and the fourth valve plate 602 closes the second air outlet section 4, so that the two ends of the main air duct 7 and the two ends of the bypass air duct 8 are respectively connected, and the fresh air entering the bypass air duct 8 from the fresh air inlet on the bypass air duct 8 can enter the main air duct 7.

[0117] Optionally, in an implementation of this embodiment, as Figure 4-6 As shown,

[0118] Controlling the first air distribution valve 5 and the second air distribution valve 6 to connect the main air duct 7 with the first air duct, and / or connecting the main air duct 7 with the second air duct includes:

[0119] like Figure 4 As shown, the first valve plate 501 and the third valve plate 601 are controlled to close both ends of the bypass air duct 8, the second valve plate 502 closes the second air inlet section 3, and the fourth valve plate 602 closes the second air outlet section 4, or, as shown Figure 5 As shown, the first valve plate 501 and the third valve plate 601 are controlled to close both ends of the bypass air duct 8, the second valve plate 502 closes the first air inlet section 1, and the fourth valve plate 602 closes the first air outlet section 2, or, as shown Figure 6 As shown, the first valve disc 501 , the second valve disc 502 , the third valve disc 601 , and the fourth valve disc 602 are controlled to close both ends of the bypass air passage 8 .

[0120] In this embodiment, before introducing fresh air into the first laundry processing drum or the second laundry processing drum, the first air inlet section 1 is closed by the first valve plate 501, the second air inlet section 3 is closed by the second valve plate 502, the first air outlet section 2 is closed by the third valve plate 601, and the second air outlet section 4 is closed by the fourth valve plate 602, so that the two ends of the main air duct 7 are connected with the two ends of the bypass air duct 8, and the fresh air entering the bypass air duct 8 from the fresh air port of the bypass air duct 8 can enter the main air duct 7, while the fresh air cannot enter the first air inlet section 1 and the second air inlet section 3, so as to prevent the fresh air with too high humidity value from directly entering the first laundry processing drum. The fresh air cannot enter the second clothes processing drum. Similarly, the fresh air cannot enter the second clothes processing drum. This design makes it easy for the humidity detection module 9 in the main air duct 7 to detect the humidity value of the introduced fresh air. If the humidity of the fresh air is larger than the preset value, it proves that the humidity of the external environment is relatively large at this time and it is not suitable to directly introduce fresh air. In this case, the dehumidification module 10 works to dehumidify the fresh air in the main air duct 7. After dehumidification, the dehumidified fresh air in the main air duct 7 is introduced into the corresponding clothes processing drum. This process can ensure that the load remains dry after drying and will not affect the original drying effect of the load.

[0121] Specifically, Figure 4As shown, the first valve plate 501 and the third valve plate 601 are controlled to close the two ends of the bypass air duct 8, the second valve plate 502 closes the second air inlet section 3, and the fourth valve plate 602 closes the second air outlet section 4. At this time, the first air duct and the main air duct 7 are in a connected state, that is, fresh air can enter the first clothing processing drum from the main air duct 7 to replace the clothes with fresh air;

[0122] like Figure 5 As shown, the first valve plate 501 and the third valve plate 601 are controlled to close the two ends of the bypass air duct 8, the second valve plate 502 closes the first air inlet section 1, and the fourth valve plate 602 closes the first air outlet section 2. At this time, the second air duct and the main air duct 7 are in a connected state, that is, fresh air can enter the second clothing processing drum from the main air duct 7 to replace the clothes with fresh air;

[0123] like Figure 6 As shown, the first valve plate 501, the second valve plate 502 and the third valve plate 601, the fourth valve plate 602 are controlled to close the two ends of the bypass air duct 8. At this time, the first air duct and the second air duct are both connected to the main air duct 7, that is, fresh air can enter the first clothing processing device and the second clothing processing device through the main air duct 7 to exchange fresh air for the clothes.

[0124] Optionally, in an implementation of this embodiment, as Figure 2 As shown,

[0125] The dehumidification module 10 includes an evaporator and a condenser integrated in a box;

[0126] Controlling the dehumidification module 10 to dehumidify the fresh air in the main air duct 7 includes:

[0127] Start the evaporator and condenser to dehumidify the fresh air.

[0128] In this embodiment, when the fresh air in the main air duct 7 needs to be dehumidified, the compressor and the condenser are started so that the fresh air in the main air duct 7 is condensed by the condenser and the integrated water droplets are discharged, thereby reducing the humidity of the fresh air in the main air duct 7.

[0129] Embodiment 2

[0130] like Figure 1 , 7 , 8, provides an electronic device, including:

[0131] a memory for storing one or more computer executable instructions;

[0132] The processor is used to call and execute computer executable instructions in the memory, so as to implement the fresh air control method in the first embodiment.

[0133] In this embodiment, the electronic device can call and execute the computer executable instructions in the memory, and in response to the fresh air start instruction, control the first air distribution valve 5 to close the first air inlet section 1 of the first air duct, the second air inlet section 3 of the second air duct, the main air duct 7 and the bypass air duct 8, and connect the main air duct 7 and the bypass air duct 8;

[0134] Control the second air distribution valve 6 to close the first air outlet section 2 of the first air duct, the second air outlet section 4 of the second air duct, the main air duct 7 and the bypass air duct 8, and connect the main air duct 7 and the bypass air duct 8;

[0135] In this way, conduction between the main air duct 7 and the bypass air duct 8 is achieved, the connection between the first air duct and the first clothing processing drum is closed, and the connection between the second air duct and the second clothing processing drum is closed, so that the introduced fresh air circulates in the main air duct 7 and the bypass air duct 8, and temporarily does not enter the first clothing processing drum and the second clothing processing drum.

[0136] The dehumidification control module 10 obtains the fresh air humidity value s in the main air duct 7, and compares the humidity value s with the preset humidity value s1.

[0137] If s<s1, the first air distribution valve 5 is controlled to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange;

[0138] If s≥s1, the dehumidification module 10 is controlled to dehumidify the fresh air in the main air duct 7, and a single fresh air exchange is completed after the dehumidification is completed.

[0139] If s<s1, it means that the external humidity is low. Figure 7 , 8 As shown, the first air division valve 5 and the second air division valve 6 are controlled to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange, that is, according to the need of introducing fresh air, fresh air is introduced into the first clothing processing drum and / or the second clothing processing drum by controlling the first air division valve 5 and the second air division valve 6. For example, when fresh air needs to be introduced into the first clothing processing drum and fresh air does not need to be introduced into the second clothing processing drum, the first air division valve 5 and the second air division valve 6 can be controlled to only connect the main air duct 7 and the first air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct, and the fresh air enters the first clothing processing drum from the first air duct to exchange the clothes in the first clothing processing drum with fresh air, thereby completing a single fresh air exchange.

[0140] If s≥s1, it proves that the humidity of the external environment is relatively high at this time, and it is not suitable to directly introduce fresh air. In this case, the dehumidification module 10 is controlled to start working, and the fresh air in the main air duct 7 is dehumidified. After the dehumidification is completed, the first air branch valve 5 and the second air branch valve 6 are controlled in the same manner as above to connect the main air duct 7 with the first air duct, and / or connect the main air duct 7 with the second air duct, and the fresh air introduction device is controlled to introduce the fresh air in the main air duct 7 into the first air duct and / or the second air duct, so as to complete a single fresh air exchange;

[0141] This process can ensure that the loads in the first laundry processing drum and the second laundry processing drum are dry after drying, and will not affect the original drying effect of the loads.

[0142] Embodiment 3

[0143] like Figure 1 , 2 As shown, a clothes processing device is provided, comprising:

[0144] The fresh air control method in the first embodiment is used for control or includes the electronic device in the second embodiment.

[0145] Specifically, the first air inlet section 1 and the first air outlet section 2 are respectively connected to the air inlet and the air outlet of the first laundry processing drum;

[0146] The second air inlet section 3 and the second air outlet section 4 are respectively connected to the air inlet and the air outlet of the second laundry processing drum;

[0147] The bypass air duct 8 has an air inlet connected to the external environment and a first port and a second port arranged opposite to each other along its extension direction;

[0148] Among them, the first port is connected to the first air inlet section 1, the second air inlet section 3 and one end of the main air duct 7, and the second port is connected to the first air outlet section 2, the second air outlet section 4 and the other end of the main air duct 7.

[0149] In this embodiment, before introducing fresh air into the first laundry processing drum or the second laundry processing drum, when the external humidity is high, such as Figure 3As shown, by pre-controlling the first air distribution valve 5 and the second air distribution valve 6, the first valve plate 501 closes the first air inlet section 1, the second valve plate 402 closes the second air inlet section 3, and at the same time, one end of the main air duct 7 is connected to the first port of the bypass air duct 8, the third valve plate 601 is controlled to close the first air outlet section 2, the fourth valve plate 602 is controlled to close the second air outlet section 4, and at the same time, the other end of the main air duct 7 is connected to the second port of the bypass air duct 8, thereby allowing 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 clothing processing drum or the second clothing processing drum as needed, thereby effectively avoiding the situation in which the surface humidity of the dried load in the washing drum is increased due to the direct introduction of fresh air to remove odor when the relative humidity of the air is high, and then the load becomes wet again, affecting the drying effect.

[0150] Specifically, when the first laundry treatment drum needs to introduce fresh air, such as Figure 4 As shown, the first valve plate 501 closes the first port of the bypass air duct 8, the second valve plate 502 closes the second air inlet section 3, the third valve plate 601 closes the second port of the bypass air duct 8, and the fourth valve plate 602 closes the air outlet of the second air outlet section 4, so that the first air inlet section 1, the main air duct 7 and the first air outlet section 2 are connected, and the fresh air in the main air duct 7 can enter the first clothes processing drum through the first air duct. This process can ensure that the load in the first clothes processing drum is dry after drying, and will not affect the original drying effect of the load;

[0151] If the second laundry treatment drum needs to introduce fresh air, Figure 5 As shown, the first valve plate 501 closes the first port of the bypass air duct 8, the second valve plate 502 closes the air inlet of the first air inlet section 1, the third valve plate 601 closes the second port of the bypass air duct 8, and the fourth valve plate 602 closes the air outlet of the first air outlet section 2, so that the second air inlet section 3, the main air duct 7 and the second air outlet section 4 are connected, and the fresh air in the main air duct 7 can enter the second clothing processing drum through the second air duct. This process can ensure that the load in the second clothing processing drum is dry after drying, and will not affect the original drying effect of the load.

[0152] If both the first laundry processing drum and the second laundry processing drum need to introduce fresh air, such as Figure 6 As shown, the first valve plate 501 and the second valve plate 502 are closed at the first port of the bypass air duct 8, and the third valve plate 601 and the fourth valve plate 602 are closed at the other port of the bypass air duct 8, so that the fresh air in the main air duct 7 can enter the first clothing processing drum through the first air duct, and enter the second clothing processing drum through the second air duct. This process can ensure that the load in the first clothing processing drum and the second clothing processing drum is dry after drying, and will not affect the original drying effect of the load.

[0153] In summary, the ingenious idea of ​​the fresh air control method lies in:

[0154] First, before the fresh air is introduced into the clothes treatment drum, the connection between the air duct and the clothes treatment drum is controlled to be closed, and the main air duct and the bypass air duct are controlled to be connected, so that the introduced fresh air circulates in the main air duct and the bypass air duct, and does not enter the clothes treatment drum temporarily. In order to avoid the excessive humidity of the fresh air affecting the drying effect of the load, the humidity value s is compared with the preset humidity value s1. When the humidity value is small, the fresh air in the main air duct is directly introduced into the clothes treatment drum that needs to introduce fresh air to complete a single fresh air exchange; when the humidity value is large, the dehumidification module is controlled to start working, and the fresh air in the main air duct is dehumidified. After the dehumidification is completed, the single fresh air exchange is completed, thereby ensuring that the load is dry after drying in the first clothes treatment drum and the second clothes treatment drum, and will not affect the original drying effect of the load.

[0155] Secondly, the design opens the air inlet and closes the air outlet for a certain period of time before opening again, so that the dehumidified fresh air can fully flow in the clothing treatment drum, thereby improving the effect of introducing fresh air and being able to remove odors more effectively. At the same time, the opening time of the air outlet is controlled to avoid introducing un-dehumidified fresh air for too long.
