[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 drying device. The clothes drying device may include a washing machine 1, and the washing machine 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 spaced apart from each other, and the fresh air inlets 12 can be provided on a window pad 13 in the washing machine 1. The number of the fresh air inlets 12 can be two, or more than two. At least two fresh air inlets 12 are connected to one of the air outlets in the household fresh air system 2 through the air inlet duct 3, and the other end of the fresh air inlet 12 is connected to the inner drum 11, so that the household fresh air system 2 can be used to introduce fresh air of a set air volume and a set temperature into the inner drum 11 through the fresh air inlet 12, thereby drying the clothes after washing or hand washing.

[0028] In one example, the longitudinal section of the air inlet duct 3 is a flat structure, with the plane perpendicular to the flow direction of the fresh air as the longitudinal section. For example, the longitudinal section of the air inlet duct 3 may include but is not limited to an ellipse. In addition, the number of the air inlet ducts 3 may be one or more, so that the space occupied by the air inlet duct 3 can be effectively reduced through the flat channel form, so as to improve the drying efficiency of the washing machine 1 while reducing the design space occupied by the air inlet duct 3 in the washing machine 1.

[0029] 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.

[0030] A heating device (not shown in the figure) is provided in the household fresh air system 2. The heating device is configured to heat the fresh air delivered to the inner drum 11 to ensure that the fresh air entering the inner drum 11 has a set temperature value. That is to say, the heating device cooperates with the air volume sensor and the control valve to ensure that the fresh air with a predetermined air volume value and a set temperature value is delivered to the inner drum 11, and then the fresh air is used to dry the clothes.

[0031] It should be noted that the heating device in the household fresh air system 2 can adopt a heating tube, a heater, etc. in the prior art, which will not be described in detail here.

[0032] The airflow input direction of each fresh air inlet 12 into the inner drum 11 is different. Such a design can achieve a mixed airflow of fresh air from different directions in the inner drum 11, thereby meeting the drying and care needs of different clothes and effectively ensuring the drying efficiency of the washing machine 1.

[0033] In this example, the clothing drying care program of the washing machine 1 is directly linked with the control module of the household fresh air system 2, the fresh air inlet switch of the washing machine 1 itself is cancelled, and the above-mentioned fresh air inlet switch is moved to the connecting pipe between the household fresh air system 2 and the washing machine 1. In this way, the control module of the household fresh air system 2 can be used to directly perform logical control on the clothing processing program of the washing machine 1, effectively enriching the usage scenarios of the household fresh air system 2.

[0034] In one example, an air outlet duct 4 is disposed inside the washing machine 1 and is arranged opposite to (eg, side by side with) the air inlet duct 3 , wherein one end of the air outlet duct 4 is connected to the gap between the inner drum 11 and the outer drum of the washing machine 1 .

[0035] Continue to refer to Figure 1 As shown, a condensation pipe 5 is also provided in the washing machine 1, and the condensation pipe 5 is arranged side by side or interlaced with the air outlet duct 4. The moisture in the fresh air of the air outlet duct 4 is condensed into liquid water by the condensation of the condensed water in the condensation pipe 5, and then the liquid water is discharged to the outside of the washing machine 1 together with the condensed water generated in the washing machine 1.

[0036] The longitudinal cross-sectional shape of the condensation duct 5 can be the same as that of the outlet duct 4, that is, the longitudinal cross-sectional shape of the condensation duct 5 is also a flat or interlaced structure, so as to achieve the condensation effect of the maximum contact area between the fresh air in the outlet duct 4 and the condensed water in the condensation duct 5. In addition, the flow direction of the condensed water in the condensation duct 5 is opposite to the flow direction of the air flow in the outlet duct 4, wherein, through the condensation of the condensed water, the fresh air at room temperature is discharged from the outlet duct 4.

[0037] Reference Figure 1 Combined with Figure 2 As shown, in one example, the air outlet duct 4 and the condensation duct 5 can be integrated in the distributor box 6 to effectively save the design space inside the washing machine 1 .

[0038] In the above examples and the following embodiments, the number of fresh air inlets 12 is two as an example for description. Figure 2 As shown, in the direction toward the door of the condensing washer-dryer, 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 of 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.

[0039] That is to say, with the plane parallel to the door of the 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 15 degrees to 160 degrees. In addition, the fresh air inlet 12 is preferably arranged towards the upper area of ​​the washing machine.

[0040] In the above embodiment, two spaced-apart fresh air inlets 12 are arranged 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 can be delivered to the inner drum through different fresh air inlets 12, so that two or more mixed air flows can be formed in the inner drum 11, and then the household fresh air system 2 is used to dry the clothes, so as to effectively improve the drying efficiency of the washing machine 1 for clothes and improve the user experience. At the same time, the clothes drying program of the washing machine 1 is linked to the household fresh air system 2, enriching the use scenarios of the household fresh air system 2.

[0041] In one example, a weight detection unit (not shown) is further provided in the washing machine 1, and the weight detection unit is used to obtain the weight of the clothes in the inner drum 11 in real time. The weight detection unit may include but is not limited to a weight sensor.

[0042] Furthermore, a humidity detection unit (not shown) is also provided in the washing machine 1, and the humidity detection unit is used to obtain the humidity in the inner drum 11 in real time. The humidity detection unit may include but is not limited to a humidity sensor or a temperature and humidity sensor.

[0043] like Figure 3 As shown, an exemplary embodiment of the present invention provides a control method for a clothes drying device. The control method for the clothes drying device comprises the following steps:

[0044] Step S100: The user terminal starts a clothes drying program.

[0045] Step S200: pre-processing the air outlet duct and the condensation pipe.

[0046] Step S300: Determine the start type of the clothes drying program.

[0047] Step S400: According to the start type of the clothes drying program, the opening of the fresh air inlet and the operating state of the inner drum are selectively controlled.

[0048] In step S100 , after the washing process of the washing machine 1 is finished, the user can start the clothes drying program of the washing machine 1 through the local end of the washing machine 1 or in the cloud.

[0049] It should be noted that the user can also control the inner drum 11 of the washing machine 1 to execute the clothes drying program through the home fresh air system 2. It should be noted that the control module of the home fresh air system 2 can adopt the control system in the prior art, as long as the control module can control various startup functions of the home fresh air system 2, and the specific structure type and specific control logic of the control module are not repeated here.

[0050] In step S200, after the user selects the corresponding clothes drying program, the air outlet duct 4 and the condensation duct 5 are pre-processed. In the process of pre-processing, the initial weight of the clothes after washing is obtained by using the weight detection unit.

[0051] Then, the air outlet duct 4 is controlled and conducted according to the control module of the home fresh air system 2 or the control module of the washing machine 1, and at the same time, the condensation duct 5 is controlled to be in an open state. That is, the air outlet duct 4 and the condensation duct 5 in the washing machine 1 are opened, so that the home fresh air system 2, the air inlet duct 3, the inner drum 11, the air outlet duct 4 and the home fresh air system 2 form a complete fresh air circulation channel, and at the same time, the condensation duct 5 is controlled to pass condensed water.

[0052] In step S300, after the air outlet duct 4 and the condensation duct 5 are opened, the home fresh air system 2 can determine the start type of the clothes drying program selected by the user, and determine when to input fresh air with a predetermined air volume value and a set temperature value into the inner drum 11, so as to use the fresh air to dry the clothes in the subsequent process.

[0053] In step S400, after determining the start type of the clothes drying program, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 can be selectively controlled by the household fresh air system 2. That is to say, different clothes drying programs correspond to different demands for fresh air volume. In this step, after determining the demand for fresh air, the control module of the household fresh air system 2 can quantify the amount of fresh air introduced into the inner drum 11 and make the part of the fresh air have a set temperature value by adjusting the opening of the control valve in conjunction with the air volume sensor and the heating device. At the same time, during the adjustment process 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 dried efficiently.

[0054] In this example, the clothes drying program is linked with the home fresh air system, and the home fresh air system 2 is used as the power source of fresh air to dry the clothes, thereby effectively improving the drying efficiency of the clothes. While improving the user experience, it enriches the usage scenarios of the home fresh air system 2.

[0055] like Figure 4 As shown, in some embodiments, the start type of the clothes drying program includes at least a timed drying mode and a smart drying mode. Among them, the drying time of the timed drying mode can be flexibly set by the user according to time or different clothes specifications or based on the factory setting of the washing machine, which is not specifically limited here.

[0056] Reference Figure 4 As described, in one example, when the household fresh air system 2 determines that the start type of the clothes drying program selected by the user is the timed drying mode, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are logically controlled based on the first control logic and the initial weight of the clothes after washing.

[0057] Specifically, the control module of the household fresh air system 2 determines the fresh air volume and the temperature of the fresh air required for drying the clothes in the inner drum 11 according to the initial weight. Then, the control module of the household fresh air system 2 controls the control valve in the air inlet duct 3 in conjunction with the air volume sensor and the heating device to deliver the fresh air in the first air volume range and at the first temperature to the inner drum 11. The first air volume range can be a fixed value or an interval value within a range. In this example, the value of the first air volume range is not specifically limited.

[0058] During the above-mentioned fresh air delivery process, the control module of the household fresh air system 2 or the control module of the washing machine 1 controls the inner drum to switch the rotation direction after each first time interval. That is to say, during the fresh air delivery process to the inner drum 11, the inner drum 11 switches from clockwise rotation to counterclockwise rotation, or adjusts from counterclockwise rotation to clockwise rotation at each first time interval. 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.

[0059] The first time is an empirical value or a theoretical value set when the washing machine leaves the factory. The first time may be any value between 10S and 60S, or other time values ​​outside the above time interval, and is not specifically limited here.

[0060] In this example, fresh air with a first air volume range and a first temperature enters the inner drum 11, and the clothes in the inner drum 11 are quickly dried. At the same time, 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 a maximum contact area, thereby further improving the drying efficiency of the clothes.

[0061] After the timing of the timed drying mode ends, the control module of the home fresh air system 2 controls and ends the operation of the timed drying mode program, that is, the washing machine 1 is stopped and the door of the washing machine 1 can be opened automatically, so that the user can take out the dried clothes in time and carry out subsequent processing, such as putting the dried clothes back into the closet.

[0062] Reference Figure 4 As described, in one example, when the home fresh air system 2 determines that the start type of the clothing drying program selected by the user is the smart drying mode, the opening of the fresh air inlet 12 and the operating state of the inner drum 11 are logically controlled based on the second control logic and the initial weight of the clothing after washing.

[0063] Specifically, the control module of the household fresh air system 2 determines the fresh air volume and the temperature of the fresh air required for drying the clothes in the inner drum 11 according to the initial weight. Then, the control module of the household fresh air system 2 controls the control valve in the air inlet duct 3 in conjunction with the air volume sensor and the heating device to deliver the fresh air in the second air volume range and at the second temperature to the inner drum 11. The second air volume range can be a fixed value or an interval value within a range. In this example, the value of the second air volume range is not specifically limited.

[0064] During the above-mentioned fresh air delivery process, the control module of the household fresh air system 2 or the control module of the washing machine 1 controls the inner drum to switch the rotation direction after every second time interval. That is to say, during the fresh air delivery process to the inner drum 11, 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 rotation direction adjustment process of the inner drum 11, the rotation speed of the inner drum 11 during the front rotation direction process may be different from or the same as the rotation speed of the inner drum 11 during the rear rotation direction process.

[0065] Among them, 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 8S and 65S, or other time values ​​outside the above time interval range, and is not specifically limited here.

[0066] Reference Figure 4 As shown, in the process of fresh air within the second air volume range and the second temperature being delivered to the inner drum 11, the humidity detection unit is used to obtain the real-time humidity value in the inner drum 11, and the weight detection unit is used to obtain the real-time weight value of the clothes in the inner drum 11, and then, the control module of the household fresh air system 2 obtains the real-time humidity value and the real-time weight value.

[0067] As the smart drying mode program continues to run, the control module of the home fresh air system 2 monitors the changing trends of the instant humidity value and the instant weight value in real time, and then adjusts the second air volume range and the second temperature of the fresh air.

[0068] In one example, as the instant humidity value and the instant weight value continue to decrease, the control module of the home fresh air system 2 adjusts the opening of the heating device and the air inlet duct 3 to reduce the input of fresh air in the second air volume range. At the same time, the second temperature of the fresh air is lowered to prevent the higher second temperature from affecting the internal structure of the clothes in the later stage of the smart drying mode.

[0069] As the instant humidity value in the inner drum 11 continues to decrease, the control module of the home fresh air system 2 determines whether the instant humidity value is lower than the preset humidity threshold. If it is detected that the instant humidity value is less than or lower than the preset humidity threshold, it is determined that the clothes in the inner drum 11 meet the clothes drying conditions, that is, at this time, the clothes are already in a dry state, and the clothes drying process can be ended.

[0070] When it is detected that the instant humidity value is still greater than the preset humidity threshold, the smart drying program will continue to be executed to ensure that the clothes can be dried thoroughly. It should be noted that the preset humidity threshold can be an empirical value or a theoretical value set when the washing machine 1 leaves the factory. In one example, the preset humidity threshold can include but is not limited to any value in the range of 32%RH to 40%RH. However, the specific value of the preset humidity threshold is not specifically limited here.

[0071] Continue to refer to Figure 4 As shown, as the smart drying mode continues, the temperature value in the inner drum 11 will continue to decrease. At this time, the temperature value in the inner drum 11 can be monitored in real time through the control mode of the home fresh air system 2. When the temperature value drops to a preset temperature value, the control module of the home fresh air system 2 controls the condensing pipe 5 in the washing machine 1 to suspend operation. When the temperature value is still higher than the preset temperature value, the condensing pipe 5 is controlled to continue to operate.

[0072] In some embodiments, after the clothes drying process ends, the control method of the clothes drying device further includes the following method:

[0073] After the scheduled drying mode or the smart drying mode is finished, the home fresh air system 2 controls and closes the air outlet duct 4. Then, the control module based on the home fresh air system 2 controls the washing machine 1 to execute the self-cleaning mode of the inner drum 11, so as to remove the lint in the process of clothes processing through the filter net provided in the air outlet duct 4, and clean the lint remaining on the inner drum 11 due to drying, so as to ensure the cleanliness of the washing machine 1 for the next use.

[0074] After the self-cleaning mode of the inner drum 11 is finished, the control module based on the household fresh air system 2 controls the washing machine 1 to perform air-drying treatment on the inner drum 11 , for example, using normal temperature fresh air to air-dry the water stains remaining in the inner drum 11 .

[0075] In the above embodiment, the clothes drying program of the washing machine 1 is linked with the home fresh air system 2, and the home fresh air system 2 is used as the power source of the fresh air, and the home fresh air system 2 provides a fresh air flow with adjustable air volume and temperature to the inner drum 11, thereby forming an adjustable mixed air flow in the inner drum 11, so as to form an efficient drying environment by using double air ducts or multiple air ducts, so as to achieve the purpose of drying different clothes. At the same time, the home fresh air system 2 is used to monitor the drying parameters (such as humidity, clothing weight, air volume and temperature, etc.) in the inner drum 11 in real time, forming a controllable and safe drying environment and a whole-house fresh air scene, thereby improving the drying efficiency of clothes and the user experience, and effectively enriching the use scenarios of the home fresh air system 2.

[0076] On the other hand, compared with the drying device in the existing washing machine, the drying device is integrated into the household fresh air system 2 in this embodiment, that is, the washing machine 1 does not need to be provided with a drying device, thereby effectively saving the design space inside the washing machine 1.
