[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0026] like Figure 1 Combined with Figure 2 As shown, an exemplary embodiment of the present invention provides a clothes air-drying device. The clothes air-drying device may include a washing machine 1, which may include but is not limited to a drum washing machine or a pulsator washing machine, etc., wherein the washing machine may also be other types of fully automatic washing machines.

[0027] The washing machine 1 is provided with at least two fresh air inlets 12 which are spaced apart and connected to the inner drum 11 of the washing machine 1. The number of the fresh air inlets 12 may be two, or more than two. The other end of any one of the at least two fresh air inlets 12 is connected to one of the air outlets in the household fresh air system 2 through the air inlet duct 3, so that the household fresh air system 2 can be used to input a suitable amount of fresh air into the inner drum 11 through the fresh air inlet 12, and then air-dry the clothes after washing or hand washing. It should be noted that the airflow input direction of each fresh air inlet 12 into the inner drum 11 is different. With such a design, a mixed airflow of fresh air airflows in different directions in the inner drum 11 can be achieved, thereby meeting the air-drying care needs of different clothes and effectively improving the air-drying efficiency of the washing machine 1.

[0028] The air inlet duct 3 is arranged inside the washing machine 1, wherein an air volume sensor (not shown in the figure) and a control valve (not shown in the figure) may be arranged in the air inlet duct 3, and the control valve and the air volume sensor may be used to quantify the air volume of the fresh air introduced into any fresh air inlet 12. The control valve may include but is not limited to a stop valve or a ball valve.

[0029] In this example, the clothes air-drying care program of washing machine 1 is directly linked with the control module of household fresh air system 2, the fresh air inlet switch of washing machine 1 itself is cancelled, and the above-mentioned fresh air inlet switch is moved to the connecting pipe between household fresh air system 2 and washing machine 1. In this way, the control module of household fresh air system 2 can be used to directly perform logical control on the clothes processing program of washing machine 1, which effectively enriches the use scenarios of household fresh air system 2.

[0030] In one example, an outlet duct 4 is further provided inside the washing machine 1 and is arranged opposite to the air inlet duct 3, wherein one end of the outlet duct 4 is communicated with the gap between the inner drum 11 and the outer drum 12 of the washing machine 1, and the other end of the outlet duct 4 can be communicated with the air outlet in the washing machine 1. That is, the fresh air in the household fresh air system 2 can enter the inner drum 11 of the washing machine 1 through the air inlet duct 3, and the clothes in the inner drum 11 are processed accordingly by the fresh air, such as air drying or cooling, etc. The fresh air after processing the clothes in the inner drum 11 can be discharged to the outside through the air outlet duct 4.

[0031] In the above examples and the following embodiments, the number of fresh air inlets 12 is two as an example for description. Figure 2As shown, in the direction facing the door of the fully automatic drum washing machine, one fresh air inlet 12 can be arranged on the upper left side of the window pad 13, and the other fresh air inlet 12 can be arranged on the upper right side of the window pad 13. The fresh air inlet 12 can also be arranged at other positions in the window pad 13, for example, the two fresh air inlets 12 can be arranged at the middle position of the left and right sides of the window pad 13; for another example, the two fresh air inlets 12 can also be arranged at the lower side positions of the left and right ends of the window pad 13.

[0032] That is to say, with the plane parallel to the door of the fully automatic drum washing machine as the longitudinal section, the angle of the projection of the fresh air input direction of the two fresh air inlets 12 on the longitudinal section is 20 degrees to 180 degrees. In addition, the fresh air inlet 12 is preferably arranged towards the upper area of ​​the washing machine.

[0033] In the above embodiment, two spaced-apart fresh air inlets 12 are provided in the inner drum 11 of the washing machine 1, and each fresh air inlet 12 is connected to the household fresh air system 2, so that fresh air of different input directions is delivered into the inner drum through different fresh air inlets 12, so as to form two or more mixed airflows in the inner drum 11, and the household fresh air system 2 is used to perform an efficient and comprehensive air-drying process on the clothes, and the fresh air is used to perform air-drying care on high-end fabrics (such as silk and woolen clothes) after washing, thereby safely and effectively maintaining such high-end fabrics, improving the user experience, and at the same time, the clothes air-drying program of the washing machine 1 is linked to the household fresh air system 2, effectively enriching the use scenarios of the household fresh air system 2.

[0034] like Figure 3 As shown, an exemplary embodiment of the present invention provides a control method for a clothes air-drying device. The control method for the clothes air-drying device comprises the following steps:

[0035] Step S100: Determine the air-drying care program type of the washing machine.

[0036] Step S200: According to the type of air-drying care program, the opening of the fresh air inlet and the operating state of the inner drum are selectively controlled.

[0037] Step S300: Determine whether the clothes in the inner drum meet the clothes air-drying conditions based on the household fresh air system.

[0038] Step S400: When the clothes in the inner drum meet the clothes air-drying conditions, the washing machine stops running.

[0039] In step S100, the control module (not shown in the figure) of the home fresh air system 2 can determine the type of air-drying care program selected by the user at the user end.

[0040] It should be noted that the control module of the household fresh air system 2 can adopt the control system in the prior art, as long as the control module can control the various startup functions of the household fresh air system 2, and the specific structural type and specific control logic of the control module will not be repeated here.

[0041] In step S200, after the user selects the corresponding air-drying care program type, the control module of the home fresh air system 2 can determine when to input fresh air into the inner drum 11. Different air-drying care program types correspond to different fresh air inputs to achieve the fresh air demand for air-drying different clothes in the inner drum 11. In this step, after determining the demand for fresh air, the control module of the home fresh air system 2 can quantify the amount of fresh air introduced into the inner drum 11 by adjusting the opening of the control valve and cooperating with the air volume sensor. At the same time, during the adjustment of the fresh air, the control module synchronously controls the operating state of the inner drum 11, for example, after controlling the inner drum 11 to rotate forward for a period of time, the inner drum 11 is controlled to rotate reversely for a period of time, so that the clothes in the inner drum 11 can be efficiently air-dried.

[0042] It should be noted that the control module of the household fresh air system 2 can also adjust the amount of fresh air input into the inner drum 11 in real time according to the weight of the clothes in the inner drum 11, the temperature and humidity in the drum, and the air volume at the air outlet.

[0043] In step S300, when the air-drying care program is finished, or when the control module of the home fresh air system 2 determines whether the clothes in the inner drum 11 meet the air-drying conditions. In one example, it can be determined based on the relationship between the weight change rate of the clothes in the inner drum 11 and the set threshold, or based on the change trend of the humidity in the inner drum 11 to determine whether the clothes have been air-dried.

[0044] In step S400, when the clothes in the inner drum 11 meet the clothes air-drying conditions, the control module of the household fresh air system 2 controls the washing machine 1 to stop running.

[0045] In this example, the air-drying program of the clothes in the washing machine 1 is linked to the household fresh air system 2, and the household fresh air system 2 is used as a fresh air power source to provide a fresh air flow with adjustable air volume, so that the mixed airflow with different air volumes in the inner drum 11 can be used to efficiently air-dry the clothes. In particular, the air-drying care function for high-end fabrics (such as silk and wool clothes) can be realized, so as to achieve the purpose of air-drying different clothes, effectively improving the user experience. At the same time, it also enriches the use scenarios of the household fresh air system 2, reflecting the concept of multiple uses and energy saving and environmental protection.

[0046] like Figure 4As shown, in some embodiments, the air-drying care program types include at least a timed air-drying mode and a smart air-drying mode. Among them, the drying time of the timed air-drying mode can be flexibly set by the user according to time or different clothing specifications or based on the factory setting of the washing machine, which is not specifically limited here.

[0047] Reference Figure 4 As shown, when the user selects the timed air-drying mode as the air-drying care program type for the clothes, the opening state of the door of the washing machine 1 is determined, and the opening degree of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the first control logic.

[0048] The first control logic includes a first sub-control logic and a second sub-control logic, wherein the first sub-control logic corresponds to a timed air-drying mode in a door-closed state, and the second sub-control logic corresponds to a timed air-drying mode in a door-open state.

[0049] In one example, when the control module of the home fresh air system 2 determines that the user has selected the timed air-drying mode with the door in the closed state, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the first sub-control logic.

[0050] Specifically, the openings of the two fresh air inlets 12 can be controlled by the control module of the household fresh air system 2 to input fresh air within a first air volume range into the inner cylinder 11 .

[0051] After the first time interval, the control module of the household fresh air system 2 switches the fresh air input direction of the fresh air inlet 12 to the fresh air output direction. That is to say, after the first time interval, the fan provided in the household fresh air system 2 can be used to rotate in the reverse direction to suck the fresh air in the inner drum 11 out through the fresh air inlet 12, so as to utilize the periodic forward and reverse flows of the fresh air flow to timely adjust the distribution state of the clothes in the inner drum 11, prevent the clothes from being too close to the front side of the inner drum 11 or the back side of the inner drum 11, and at the same time, enable the fresh air to fully contact the clothes, thereby improving the air-drying efficiency of the clothes.

[0052] It should be noted that the first time is an empirical value or a theoretical value set when the washing machine leaves the factory. The first time can be any value between 10S and 80S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0053] During the switching of the fresh air flow direction, the control module of the household fresh air system 2 controls the inner drum 11 to switch the rotation direction after every second time interval. That is, every second time interval, the inner drum 11 switches from clockwise rotation to counterclockwise rotation, or adjusts from counterclockwise rotation to clockwise rotation. It should be noted that during the adjustment of the rotation direction of the inner drum 11, the rotation speed of the inner drum 11 during the front rotation direction may be different from or the same as the rotation speed of the inner drum 11 during the rear rotation direction.

[0054] It should be noted that the second time is an empirical value or a theoretical value set when the washing machine leaves the factory. The second time can be any value between 10S and 40S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0055] During the periodic forward and reverse flow of the fresh air flow, the rotation direction of the inner drum 11 is adjusted to fully shake out the clothes so that the clothes are in contact with the fresh air with the maximum contact area, thereby further improving the air-drying efficiency of the clothes.

[0056] After the timing time of the timed air-drying mode ends, the control module of the home fresh air system 2 controls the end of the timed air-drying mode, that is, stops the operation of the washing machine 1, so that the user can take out the air-dried clothes in time and perform subsequent processing, such as putting the air-dried clothes back into the closet.

[0057] In another example, when the control module of the home fresh air system 2 determines that the user has selected the timed air-drying mode with the machine door in the open state, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the second sub-control logic.

[0058] Specifically, the openings of the two fresh air inlets 12 can be controlled by the home fresh air system 2 control module to input fresh air in the second air volume range into the inner cylinder 11 .

[0059] After the third time has passed, the control module of the household fresh air system 2 switches the fresh air input direction of the fresh air inlet 12 to the fresh air output direction. That is, after the third time has passed, the fan provided in the household fresh air system 2 can be used to rotate in the reverse direction to suck the fresh air in the inner drum 11 out through the fresh air inlet 12, so as to utilize the periodic forward and reverse flows of the fresh air flow to timely adjust the rotation state of the clothes in the inner drum 11, prevent the clothes from being too close to the front side of the inner drum 11 or the rear side of the inner drum 11, and at the same time, enable the fresh air to fully contact the clothes, thereby improving the air-drying efficiency of the clothes.

[0060] It should be noted that the third time is an empirical value or a theoretical value set when the washing machine leaves the factory, and the first time can be any value between 20S and 85S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0061] During the switching of the fresh air flow direction, the control module of the household fresh air system 2 controls the inner drum 11 to switch the rotation direction after every fourth time interval. That is, every fourth time interval, the inner drum 11 switches from clockwise rotation to counterclockwise rotation, or adjusts from counterclockwise rotation to clockwise rotation. It should be noted that during the adjustment of the rotation direction of the inner drum 11, the rotation speed of the inner drum 11 during the front rotation direction may be different from or the same as the rotation speed of the inner drum 11 during the rear rotation direction.

[0062] It should be noted that the fourth time is an empirical value or a theoretical value set when the washing machine leaves the factory. The fourth time can be any value between 8S and 36S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0063] During the periodic forward and reverse flow of the fresh air flow, the rotation direction of the inner drum 11 is adjusted to fully shake out the clothes so that the clothes are in contact with the fresh air with the maximum contact area, thereby further improving the air-drying efficiency of the clothes.

[0064] After the timing time of the timed air-drying mode ends, the control module of the home fresh air system 2 controls the end of the timed air-drying mode, that is, stops the operation of the washing machine 1, so that the user can take out the air-dried clothes in time and perform subsequent processing, such as putting the air-dried clothes back into the closet.

[0065] It should be noted that, in order to prevent the clothes from being blown out of the inner drum 11, the upper limit of the second air volume range in the timed air drying mode in the door open state is smaller than the lower limit of the first air volume range. At the same time, in order to ensure that the clothes are kept in the middle position of the inner drum 11 as much as possible, the third time for switching the fresh air flow direction in the timed air drying mode in the door open state is also shorter than the first time in the door closed state.

[0066] Reference Figure 4 As shown, when the user selects the smart air-drying mode as the air-drying care program type for the clothes, the opening state of the door of the washing machine 1 is determined, and the opening degree of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the second control logic.

[0067] The second control logic includes a third sub-control logic and a fourth sub-control logic, wherein the third sub-control logic corresponds to the smart air-drying mode in the door-closed state, and the fourth sub-control logic corresponds to the smart air-drying mode in the door-open state.

[0068] In one example, when the control module of the home fresh air system 2 determines that the user has selected the smart air-drying mode with the door in the closed state, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the third sub-control logic.

[0069] Specifically, the openings of the two fresh air inlets 12 can be controlled by the control module of the household fresh air system 2 to input fresh air in the third air volume range into the inner cylinder 11 .

[0070] After the fifth time interval, the control module of the household fresh air system 2 switches the fresh air input direction of the fresh air inlet 12 to the fresh air output direction. That is to say, after the fifth time interval, the fan provided in the household fresh air system 2 can be used to rotate in the reverse direction to suck the fresh air in the inner drum 11 out through the fresh air inlet 12, so as to utilize the periodic forward and reverse flows of the fresh air flow to timely adjust the rotation state of the clothes in the inner drum 11, prevent the clothes from being too close to the front side of the inner drum 11 or the back side of the inner drum 11, and at the same time, enable the fresh air to fully contact the clothes, thereby improving the air-drying efficiency of the clothes.

[0071] It should be noted that the fifth time is an empirical value or a theoretical value set when the washing machine leaves the factory. The fifth time can be any value between 10S and 90S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0072] During the switching of the fresh air flow direction, the control module of the household fresh air system 2 controls the inner drum 11 to switch the rotation direction after every sixth time interval. That is, every sixth time interval, the inner drum 11 switches from clockwise rotation to counterclockwise rotation, or adjusts from counterclockwise rotation to clockwise rotation. It should be noted that during the adjustment of the rotation direction of the inner drum 11, the rotation speed of the inner drum 11 during the front rotation direction may be different from or the same as the rotation speed of the inner drum 11 during the rear rotation direction.

[0073] It should be noted that the sixth time is an empirical value or a theoretical value set when the washing machine leaves the factory. The sixth time can be any value between 10S and 75S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0074] During the periodic forward and reverse flow of the fresh air flow, the rotation direction of the inner drum 11 is adjusted to fully shake out the clothes so that the clothes are in contact with the fresh air with the maximum contact area, thereby further improving the air-drying efficiency of the clothes.

[0075] When the program of the smart air-drying mode is finished, the control module of the home fresh air system 2 controls the end of the operation of the smart air-drying mode, that is, stops the operation of the washing machine 1, so that the user can take out the clothes after the air-drying process in time and continue with subsequent processing, such as putting the clothes after the air-drying process in the closet.

[0076] Among them, the upper limit value of the second air volume range is smaller than the lower limit value of the third air volume range, and the value range of the third air volume range can be the same as the value range of the first air volume range, or the value range of the third air volume range is slightly smaller than the value range of the first air volume range.

[0077] Moreover, the third time for switching the fresh air flow direction in the timed air-drying mode in the door-open state is also shorter than the fifth time for switching the fresh air flow direction in the smart air-drying mode in the door-closed state, and the first time for switching the fresh air flow direction in the air-drying mode in the door-closed state can be the same as the above-mentioned fifth time, or the above-mentioned fifth time is slightly longer than the above-mentioned first time.

[0078] In another example, when the control module of the home fresh air system 2 determines that the user has selected the smart air-drying mode with the machine door in the open state, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are controlled based on the fourth sub-control logic.

[0079] Specifically, the user selects the inner drum 11 of the washing machine 1 to execute the program of the smart air-drying mode, but the door of the washing machine 1 is in an open state. At this time, the control mode of the home fresh air system 2 can issue a warning message to prompt the user to close the door of the washing machine 1 in time.

[0080] After the door of the washing machine 1 is closed again, the control mode of the household fresh air system 2 continues to run the smart air-drying mode. At this time, the opening of the fresh air inlet 12 and the operation mode of the inner drum 11 can be controlled by the third sub-control program until the program operation of the smart air-drying mode is completed.

[0081] It should be noted that during the operation of the smart air-drying mode, the air volume in the third air volume range and the interval time for switching the fresh air flow direction (i.e., the fifth time) will change with the weight change rate and humidity in the inner drum 11 to ensure that the clothes are maintained in the middle area of ​​the inner drum 11 as much as possible, thereby achieving the maximum air-drying efficiency of the clothes. For example, as the weight change rate of the clothes in the inner drum 11 decreases, the fresh air volume input into the inner drum 11 in the smart air-drying mode also decreases, and the interval time for each switching of the fresh air flow direction (i.e., the fifth time) is also shortened. Among them, the weight change rate of the clothes (which can also be the weight difference) is used to characterize the difference between the initial weight of the clothes after washing and the instantaneous weight of the clothes during any air-drying process.

[0082] For another example, as the humidity in the inner drum 11 decreases, the amount of fresh air input into the inner drum 11 in the smart air-drying mode also decreases, and the interval time (i.e., the fifth time) of each switching of the fresh air flow direction is also shortened.

[0083] On the other hand, the first air volume range in the timed air-drying mode with the door closed is larger than the average air volume in the smart air-drying mode to ensure that the clothes are air-dried within a fixed time.

[0084] like Figure 4 As shown, in some embodiments, the following method can be used to determine whether the clothes in the inner drum 11 meet the clothes air-drying conditions:

[0085] During the operation of the air-drying care program type, the weight change rate of the clothes in the inner drum 11 is obtained in real time, or the comparison result between the humidity in the inner drum 11 and the preset threshold is obtained. The weight change rate can be used to represent the difference change process between the initial weight of the clothes after washing and the instantaneous weight of the clothes during the air-drying process.

[0086] Then, according to the weight change rate of the clothes or the above comparison result, it is determined whether the clothes in the inner drum 11 meet the clothes air-drying conditions.

[0087] When the weight change rate of the clothes is lower than the threshold value, or the humidity in the inner drum 11 is lower than the preset threshold value, it indicates that the weight of the clothes is no longer changing, that is, the clothes are already in a dry state at this time, so it can be determined that the clothes in the inner drum 11 meet the clothes air-drying conditions. Then, the control module of the home fresh air system 2 can control the washing machine to stop running, open the door of the washing machine 1, and generate a prompt message to remind the user to take out the clothes in time.

[0088] It should be noted that the determination of the clothing air-drying conditions in this example can be applied to the above-mentioned timed air-drying mode and the smart air-drying mode, but is mainly applied to the smart air-drying mode. The timed air-drying mode can also be based on the end of the program operation, that is, when the program operation of the timed air-drying mode is completed, it indicates that the clothes are finished drying. After the door of the washing machine 1 is opened, the user puts the air-dried clothes back into the closet.

[0089] In the above embodiment, the household fresh air system 2 is used as the power source of fresh air, thereby providing the inner drum 11 of the washing machine 1 with positive and negative fresh air airflows with adjustable air volume, so as to form a high-efficiency and adjustable diverse mixed airflow environment in the inner drum 11. At the same time, the control module based on the household fresh air system 2 monitors the humidity, clothing weight and air volume parameters in the inner drum 11, thereby forming a gentle care environment for clothing, thereby achieving the purpose of air-drying different clothing, especially realizing the air-drying care function for high-end fabrics such as silk and wool clothing, thereby improving the user experience; on the other hand, the clothing air-drying program of the washing machine 1 is linked to the household fresh air system 2, which effectively enriches the use scenarios of the household fresh air system 2.
