In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.
[0049] The technical solution of this embodiment is described in detail below with reference to the accompanying drawings. The following embodiments and examples can be combined with each other unless there is any conflict.
[0050] According to an exemplary embodiment, Figures 1-6 As shown, this embodiment proposes a clothing processing device with a drying function, and the clothing loading port of the clothing processing device can be located at the top of the clothing processing device or at the side of the clothing processing device. The clothing processing device includes an inner drum 1, a driving mechanism, a transmission mechanism and an air supply mechanism, wherein the bottom of the inner drum 1 is provided with a plurality of first flow holes 12, and the plurality of first flow holes 12 can allow air or water to pass through. The wall of the drying drum also has a plurality of second flow holes 13, and the second flow holes 13 can also allow air or water to pass through. The driving mechanism is connected to the bottom of the inner drum 1, and the driving mechanism can drive the inner drum 1 to rotate. The transmission mechanism is arranged on the back side of the bottom of the drum and is connected to the driving mechanism, and the transmission mechanism can rotate with the driving mechanism. The transmission mechanism is, for example, a gear transmission or a combination of a transmission disc and a belt for transmission. The air supply mechanism includes an air duct structure 42 and a fan component 41. The air duct structure 42 connects the first flow hole 12 and the second flow hole 13. The fan component 41 is located in the air duct structure 42 and is connected to the transmission mechanism. The transmission mechanism can drive the fan component 41 to rotate when the driving mechanism drives the inner drum 1 to rotate in a preset direction, so that the drying airflow of the inner drum 1 is at least partially discharged from the first flow hole 12 to the air duct structure 42 under the action of the fan component 41 and returns to the inner drum 1 through the air duct structure 42 and the second flow hole 13. For example, refer to Figure 6, multiple first flow holes 12 are located at a position on the bottom of the cylinder opposite to the air inlet end of the first air duct 421.
[0051] In this embodiment, an air supply mechanism is provided, and the air duct structure 42 of the air supply mechanism connects the first flow hole 12 located at the bottom of the inner drum 1 with the second flow hole 13 located on the wall of the inner drum 1. The driving mechanism drives the fan component 41 of the air supply mechanism to rotate through the transmission mechanism. Under the action of the fan component 41, a circulating airflow is formed between the first flow hole 12 and the second flow hole 13. Before drying and after dehydration, the circulating airflow between the first flow hole 12 and the second flow hole 13 can enhance the effect of shaking out the clothes and prevent the clothes from sticking to the drum wall and affecting the drying effect. During the drying process, the circulating airflow between the first flow hole 12 and the second flow hole 13 enhances the forced convection heat exchange at the bottom of the inner drum 1, accelerates the heat and moisture exchange rate between the clothes at the bottom of the inner drum 1 and the circulating air, and improves the tossing of the clothes in the drum, thereby shortening the overall drying time, improving the drying uniformity, and improving the flatness of the clothes.

The second drive shaft 23 is parallel to the first drive shaft 22 and connected to the bottom of the drum. The fan component 41 is disposed on the second drive shaft 23 and can rotate relative to the second drive shaft 23. This allows a speed difference between the fan component 41 and the inner drum 1 to be achieved based on the same driving force, thereby meeting the low speed requirement for the inner drum 1 during drying and the high speed requirement for the fan component 41. The transmission mechanism includes a first transmission component 31 and a second transmission component 32. The first transmission component 31 connects the first drive shaft 22 to the fan component 41, and the second transmission component 32 connects the first drive shaft 22 to the second drive shaft 23.

Exemplarily, the fan component 41 includes a plurality of blades, which are fixed to the second gear and arranged along the circumference of the second gear. The rotation of the second gear drives the plurality of blades to rotate.
[0054] And / or, the second transmission component 32 includes a third gear and a fourth gear, the third gear is fixed to the first drive shaft 22, the fourth gear is fixed to the second drive shaft 23, the third gear is meshed with the fourth gear, and the ring gear radius of the third gear is smaller than the ring gear radius of the fourth gear to ensure a lower rotation speed of the inner drum 1 during drying.

The second transmission disc 312 can rotate relative to the second drive shaft 23. The fan component 41 is connected to the second transmission disc 312. The rotation of the second transmission disc 312 can drive the blades of the fan component 41 to rotate. The two ends of the first belt 313 are respectively wrapped around the first transmission disc 311 and the second transmission disc 312. The diameter of the first transmission disc 311 is larger than the diameter of the second transmission disc 312 to ensure a higher rotation speed of the fan component 41. Exemplarily, the fan component 41 includes a plurality of blades, which are fixed to the second transmission disc 312 and arranged along the circumferential direction of the second transmission disc 312. The rotation of the second transmission disc 312 drives the plurality of blades to rotate.
[0056] And / or, the second transmission component 32 includes a third transmission disc 321, a fourth transmission disc 322 and a second belt 323, the third transmission disc 321 is fixed to the first drive shaft 22, the fourth transmission disc 322 is fixed to the second drive shaft 23 at a position opposite to the first transmission disc 311, and the two ends of the second belt 323 are respectively wound around the third transmission disc 321 and the fourth transmission disc 322, and the diameter of the third transmission is smaller than the diameter of the fourth transmission disc 322 to ensure a lower rotation speed of the inner drum 1 during drying.
[0057] In a preferred embodiment, when applied to a clothing processing device with a washing function, the blade surface of the fan component 41 and the transmission mechanism are treated with anti-corrosion to avoid rust and corrosion caused by contact with water during washing.
[0058] In some embodiments, as Figure 2 As shown, the air duct structure 42 includes a first air duct 421 and a second air duct 422. The first air duct 421 is arranged on the back side of the cylinder bottom and is arranged along the radial direction of the cylinder bottom. The fan component 41 is arranged in the first air duct 421. The second air duct 422 is arranged on the cylinder wall of the inner cylinder 1. The second air duct 422 connects the first air duct 421 with the plurality of second flow holes 13. For example, refer to Figure 2, the second air duct 422 extends along the axial direction of the inner tube 1. In a preferred embodiment, there are multiple first air ducts 421 and second air ducts 422, and the first air ducts 421 and the second air ducts 422 are arranged in a one-to-one correspondence. The multiple first air ducts 421 are radially arranged at the bottom of the inner tube 1, and the fan component 41 is located at the center of the multiple first air ducts 421. The airflow generated by the fan component 41 can enter the multiple first air ducts 421. Multiple second flow holes 13 are respectively provided on the side wall of the inner tube 1 at positions corresponding to the air outlets of the second air ducts 422, so that air circulation is achieved at different positions on the side wall of the inner tube 1 in the circumferential direction, thereby enhancing the shaking and drying effects at different positions on the side wall of the inner tube 1.
[0059] In some embodiments, as Figure 4 As shown, the clothes processing device includes a tripod 5, which is fixed to the back side of the bottom of the drum, the second drive shaft 23 is fixed to the center of the tripod 5, and the first air duct 421 is provided on at least one support arm of the tripod 5. The fan component 41 is coaxial with the tripod 5, and the fan component 41 and the second transmission component 32 are sleeved on the axis of the tripod 5. The tripod 5 is connected to the inner drum 1 by screws. In one example (not shown in the figure), a cavity is formed in the support arm, and the first air duct 421 is formed in the inner cavity of the apex. In another example, referring to Figure 2 The second air duct 422 is fixed to the side of the support arm facing away from the inner drum 1 and extends in the same direction as the support arm. For example, the tripod 5 has three support arms, each of which is provided with a first air duct 421. This embodiment arranges the first air duct 421 based on the structure of the tripod 5, which not only saves internal space of the clothes processing device but also ensures the reliability of the first air duct 421.
[0060] In some embodiments, as Figure 3 As shown, a convex 15 is provided on the inner wall of the inner tube 1 at a position corresponding to the air outlet end of the second air duct 422. The second flow hole 13 is located on the convex 15 and extends along the radial direction of the inner tube 1. The multiple second flow holes 13 input air flow into the inner tube 1 in the structure of multiple parallel air ducts, so that the air flow of the multiple second flow holes 13 can be blown into the inner tube 1 to straighten the air flow, and the air flow intensity of the second flow holes 13 can be enhanced to improve the shaking effect.
[0061] In some embodiments, as Figure 1 As shown, a plurality of lifting ribs 11 are provided on the inner wall surface of the inner drum 1. The plurality of lifting ribs 11 are arranged at intervals along the circumferential direction of the inner drum 1. A convex hull 15 is provided between each adjacent lifting rib 11. A plurality of second flow holes 13 are provided in each convex hull 15. Thus, under the dual action of the lifting ribs 11 and the airflow blown out by the second flow holes 13, all clothes attached to the wall of the inner drum 1 can be better shaken out.
[0062] In some embodiments, as Figure 3 As shown, a plurality of drainage holes 423 are provided in the second air duct 422 at a position opposite to the flow holes. This allows water in the inner drum 1 to enter the air duct structure 42 through the second flow holes 13 when the laundry processing device is performing a washing cycle. The water entering the air duct structure 42 can then be discharged through the drainage holes 423. The size of the drainage holes 423 should not be too large to prevent the airflow in the second air duct 422 from being discharged through the drainage holes 423.
[0063] In some embodiments, as Figure 3 As shown, the air duct structure 42 further includes a plurality of guide plates 424, which are arranged at positions corresponding to the plurality of drainage holes 423 within the second air duct 422. The plurality of guide plates 424, on the one hand, guide the airflow within the second air duct 422 into the second flow holes 13, and on the other hand, reduce the amount of airflow within the second air duct 422 discharged from the drain port. In a preferred embodiment, the plurality of guide plates 424 correspond one-to-one to the plurality of drainage holes 423, and the guide plates 424 are arranged at an angle away from the bottom of the inner tube 1 from the drainage holes 423.
[0064] In some embodiments, as Figure 2-Figure 4 、 Figure 6 As shown, the clothing processing device includes an outer drum (not shown in the figure), an inner drum 1 is arranged in the outer drum, an air supply mechanism is located between the outer drum and the inner drum 1, and a plurality of third flow holes 14 are respectively provided on the drum wall and / or the drum bottom of the inner drum 1, and the third flow holes 14 can also allow airflow or water to pass through. In the washing process, water circulates between the inner drum 1 and the outer drum through the third flow holes 14, and in the drying process, airflow flows into the inner drum 1 and the outer drum through the third flow holes 14. Exemplarily, a plurality of third flow holes 14 are provided on the drum bottom and the drum wall of the inner drum 1, the plurality of third flow holes 14 located at the drum bottom are evenly distributed between the two adjacent support arms of the tripod 5, and the plurality of third flow holes 14 located on the drum wall are evenly arranged along the circumferential direction and axial direction of the drum wall.
[0065] In some embodiments (not shown in the figures), a door seal is provided at the opening of the inner drum 1, the door seal having an air inlet, and an air outlet is provided on the wall of the outer drum. The clothing processing apparatus includes a drying system, which includes a drying air duct. Dry air circulates in the drying air duct, which is generated by a heat pump system or by electrical heating. The air outlet of the drying air duct is connected to the air inlet, and the air inlet is connected to the air outlet. For a drying device with an air inlet at the front of the clothing processing device, when there are a lot of clothes in the drum, the wind resistance at the bottom of the inner drum 1 is large, resulting in poor heat and moisture exchange between the clothes at the bottom of the inner drum 1 and the circulating air. By providing an air supply mechanism and connecting the first flow hole 12 at the bottom of the inner drum 1 and the second flow hole 13 at the wall of the inner drum 1 through the air duct structure 42 of the air supply mechanism, the driving mechanism drives the fan component 41 of the air supply mechanism to rotate through the transmission mechanism. Under the action of the fan component 41, a circulating airflow is formed between the first flow hole 12 and the second flow hole 13. Under the action of the fan component 41, a circulating airflow is formed between the bottom and the wall of the inner drum 1, thereby enhancing the shaking effect on the clothes and preventing the clothes from sticking to the wall and affecting the drying effect. At the same time, the forced convection heat exchange at the bottom of the inner drum 1 during drying of the clothes processing device is enhanced, the heat and moisture exchange rate between the clothes at the bottom of the inner drum 1 and the circulating air is accelerated, and the tossing of the clothes in the drum is improved, thereby shortening the overall drying time, improving the drying uniformity, and improving the flatness of the clothes.
[0066] This embodiment provides a control method for a drying device, which is used to control any drying device provided in the first aspect of the present invention. Figure 7 is a control flow chart of a drying device according to an exemplary embodiment, referring to Figure 7 , the control method comprises the following steps:
[0067] S71, after the dehydration process is completed and before the drying process begins, the clothes processing device controls the inner drum 1 to rotate at an initial speed;
[0068] S72, obtaining the eccentricity value of the inner cylinder 1, and comparing the eccentricity value with a preset eccentricity value;
[0069] S73. When the eccentricity value is less than or equal to the preset eccentricity value, control the inner drum 1 to operate at a third speed with a third rotation-stop ratio; when the eccentricity value is greater than the preset eccentricity value, enter the drying program.
[0070] In this embodiment, after the dehydration process is complete and before the drying process begins, the laundry processing device first controls the inner drum to operate at an initial speed. The measured eccentricity value is recorded as P and compared with a preset eccentricity value Ps. When the laundry adheres to the walls of the inner drum 1, the eccentricity value is relatively small. Therefore, when the eccentricity value P is less than Ps, the inner drum 1 operates at a third speed V3 and a third rotation-stop ratio R3 for a predetermined time. V3 is, for example, 30-80 rpm. The third rotation-stop ratio R3 is characterized by a forward rotation duration greater than a reverse rotation duration, and a very short reverse rotation duration. This allows the second flow holes 13 to continuously supply air, allowing the laundry adhered to the walls to be released from the walls of the inner drum 1 by the air entering through the second flow holes 13. After the predetermined period of operation, the eccentricity value is re-tested. When the eccentricity value P is greater than or equal to Ps, the laundry is deemed to have been released from the walls. The drying process then begins, and the drying system is activated.
[0071] Continue to refer to Figure 7 , after entering the drying program, the control method includes:
[0072] S74, controlling the inner drum 1 to rotate alternately forward and reverse at a first speed and a first start-stop ratio;
[0073] S75, obtaining the air outlet temperature and air outlet humidity of the clothes;
[0074] S76: When the outlet air temperature is greater than or equal to the set temperature and the outlet air humidity is greater than or equal to the set humidity, control the inner drum 1 to operate at the second speed and the second start-stop ratio.
[0075] In this embodiment, during the drying process, the drying system is activated, such as a heat pump drying system or an electrically heated drying system. The drying system's circulating fan is activated, and a temperature sensor and a humidity sensor are provided at the washing machine's air outlet. The temperature sensor detects the outlet air temperature, while the humidity sensor detects the outlet air humidity. Because the rotational power of the inner drum 1 and the fan component 41 both originate from the drive mechanism, the forward rotation of the drive mechanism's motor 21 drives the inner drum 1 forward, causing the fan component 41 to rotate and generate airflow. However, reverse rotation of the motor 21 results in no airflow from the fan component 41. Prolonged single-direction rotation of the inner drum 1 can cause the clothing inside to become tangled and knotted, hindering drying. Furthermore, in the early stages of drying, the moisture content of the clothing on the inner drum 1's walls is still high, and the system's moisture retention and dehumidification capacity are already maintained at high levels. At this point, the fan component 41 has limited effectiveness. Therefore, after drying begins, the controller records the outlet air temperature and humidity of inner drum 1 and compares them to the preset temperature Ts and humidity Hs. When the temperature and humidity reach Ts and Hs, respectively, the clothes around inner drum 1 are considered relatively dry, with a significant difference in moisture level from the clothes at the bottom. At this point, fan component 41 is more effective. Before the temperature and humidity reach Ts and Hs, inner drum 1 operates at a first speed V1 and a first run-stop ratio R1. V1 can range from 30 rpm to 60 rpm. The first run-stop ratio R1 is characterized by equal forward and reverse rotation times. During this stage, fan component 41 operates for a shorter period of time, primarily to dry the clothes around inner drum 1 and prevent them from becoming tangled or entangled. After reaching the set temperature and humidity, inner drum 1 operates at a second speed V2 and a second run-stop ratio R2. V2 can be 40-80 rpm, with V2 > V1. The second run-stop ratio R2 is characterized by a forward rotation duration greater than a reverse rotation duration, a shorter reverse rotation duration, and a forward rotation duration less than a forward rotation duration in the third run-stop ratio. During this phase, fan component 41 operates for a prolonged period, enhancing heat exchange at the bottom of inner drum 1. The machine then continues operating at the second speed V2 and the second run-stop ratio R2 until the drying criteria are met and drying is complete.
