It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0035] This application provides a drying system applied to a clothes dryer. The dryer can be a drying device with only drying function, or it can be a washer-dryer combo with both washing and drying functions. For example, please refer to... Figure 1 , Figure 1 This is a schematic diagram of a first structure of a drying system provided in an embodiment of this application. The drying system 100 includes a drum 4, a heat source 3, an air power source 1, and an air amplifier 2.

[0036] The roller 4 is used to hold the clothes to be processed; the heat source 3 is used to output heat; the air power source 1 is used to output powered air; the air amplifier 2 includes an amplification cavity with an output port 23, which is connected to the air inlet of the roller 4. The amplification cavity is used to receive heat and powered air, and amplify the internal airflow velocity to deliver high-temperature and high-speed airflow to the roller 4.

[0037] It should be noted that the air amplifier 2 is a device that uses the Venturi effect to amplify the internal airflow velocity. Heat and kinetic air mix upon entering the amplification chamber to form a high-temperature airflow. This high-temperature airflow, after being amplified, becomes a high-temperature, high-speed airflow. By supplying this high-temperature, high-speed airflow to the drum 4, the airflow within the drum 4 is increased, thereby increasing the amount of moisture carried away from the clothes to be treated per unit time. The output port 23 and the air inlet of the drum 4 can be connected via an air supply duct. The drum 4 also has an air outlet. The high-temperature, high-speed airflow entering the drum 4 evaporates the water in the clothes to be treated, forming a humid, hot airflow. This humid, hot airflow flows out through the air outlet of the drum 4, for example, into the external environment 6 of the dryer 10.

[0038] The drying system 100 provided in this application embodiment amplifies the flow rate of the high-temperature airflow used to input the drum 4 by adding an air amplifier 2, which can increase the flow rate of the high-temperature air in the drum 4, accelerate the evaporation of moisture in the clothes to be treated in the drum 4, and thus improve the drying efficiency of the clothes.

[0039] In some embodiments, such as Figure 1 As shown, the amplification cavity also has a first input port 22 and a second input port 21. The first input port 22 is connected to the output end of the heat source 3, and the second input port 21 is connected to the output end of the air power source 1. The amplification cavity is used to receive heat through the first input port 22 and to receive powered air through the second input port 21. During the operation of the drying system 100, the air power source 1 continuously supplies powered air to the amplification cavity through the second input port 21, thereby creating a negative pressure at the first input port 22. Under the action of the negative pressure, the heat generated by the heat source 3 is continuously drawn into the amplification cavity. The first input port 22 and the output end of the heat source 3, and the second input port 21 and the output end of the air power source 1, can be connected by air supply ducts.

[0040] In some other embodiments, the air power source 1, the heat source 3, and the amplification cavity can be connected in sequence. The powered air output from the air power source 1 flows through the heat source 3 and then enters the amplification cavity. When the powered air flows through the heat source 3, it will carry away the heat in the heat source 3 so as to input high-temperature powered air into the amplification cavity.

[0041] Optionally, the air power source 1 is a compressor, which can be a centrifugal compressor, screw compressor, reciprocating compressor, or other types of compressor, without specific limitations. Optionally, the heat source 3 includes one or more of the following: heating wire, heating rod, heating tube, and vortex tube 8.

[0042] For further details, please refer to Figure 2 , Figure 2This is a second structural schematic diagram of the drying system provided in the embodiments of this application. The dryer 10 includes a drive unit 5, which is connected to the drum 4 and is used to drive the drum 4 to rotate; the heat source 3 includes a vortex tube 8, which includes an air inlet 81, a hot outlet 82, and a cold outlet 83. The air inlet 81 is used to input air, and the vortex tube 8 is used to separate the internal air into hot air and cold air; the hot outlet 82 is connected to the first input port 22 and is used to output hot air; the cold outlet 83 is used to output cold air to the drive unit 5.

[0043] It should be noted that the vortex tube 8 is a device that uses high-speed airflow to generate a temperature difference, capable of separating compressed air into two streams of air: hot and cold. The vortex tube 8 includes a nozzle and a vortex chamber. The nozzle is used to accelerate the input air and guide it into the vortex tube 8. The vortex chamber is a cylindrical cavity in which the air forms a high-speed rotating vortex under the guidance of the nozzle. The high-speed rotating airflow generates centrifugal force, pushing the heavier cold molecules towards the center of the vortex, while the lighter hot molecules are pushed towards the outer edge of the vortex. Thus, the cold air is discharged from the cold outlet 83 through the central channel of the vortex tube 8, and the hot air is discharged from the hot air outlet through the side channels of the vortex tube 8.

[0044] The vortex tube 8 inputs hot air into the amplification cavity through the first inlet 22. The hot air contains the aforementioned heat. The cold air generated by the vortex tube 8 is then delivered to the drive unit 5, which cools the drive unit 5, thereby improving its working efficiency and reducing energy consumption. In this way, both cold and hot air can be fully utilized, reducing product energy consumption and achieving energy conservation and environmental protection. The drive unit 5 can be a drive motor, and the output shaft of the drive motor is fixedly connected to the roller 4, suitable for driving the roller 4 to rotate.

[0045] Optionally, the air inlet 81 is connected to the output terminal of the aerodynamic source 1 to receive the powered air output by the aerodynamic source 1. That is, the aerodynamic source 1 has two powered air output terminals, which are used to output powered air to the vortex tube 8 and the air amplifier 2 respectively.

[0046] In some embodiments, please refer to Figure 3 , Figure 3 This is a schematic diagram of a third structure of the drying system provided in this application embodiment. The drying system 100 also includes a dehumidifier 9. The drum 4 includes an air outlet for outputting hot and humid airflow, and the air outlet is connected to the inlet of the dehumidifier 9. The dehumidifier 9 is used to remove water from the hot and humid airflow. The dehumidifier 9 can be used to adsorb moisture to remove water from the hot and humid airflow; for example, the dehumidifier 9 is a molecular sieve purifier, a liquid air adsorber, or other device capable of adsorbing water. Alternatively, the dehumidifier 9 can be used to exchange heat with the hot and humid airflow to remove water from the hot and humid airflow; for example, the dehumidifier 9 is a finned heat exchanger or other heat exchange device.

[0047] It should be noted that after removing water from the humid airflow, the dehumidifier 9 outputs dry, hot air. This hot air can be directly delivered to the external environment 6 or delivered to the heat source 3 for heat reuse. Optionally, the air outlet of the dehumidifier 9 is connected to the input of the heat source 3; in this way, the drying system 100 can be set as an airflow circulation system, instead of exhausting airflow to the external environment 6, the heat is recycled. This protects the user's home environment from exhaust gas pollution and fully recovers and utilizes system energy to reduce energy consumption.

[0048] In some embodiments, such as Figures 2-4 As shown, Figure 4 This is a fourth structural schematic diagram of the drying system provided in the embodiments of this application. The drying system 100 also includes a control board 7, electrically connected to the air power source 1, used to monitor the temperature of the drum 4 and to adjust the air output of the air power source 1. It can be understood that by adjusting the air output of the air power source 1, the negative pressure at the first inlet 22 can be changed, thereby changing the amount of heat absorbed by the first inlet 22, thus changing the heat output from the amplifier to the drum 4, achieving temperature control of the drum 4. Optionally, the control board 7 is used to adjust the air output of the air power source 1 according to the actual temperature of the drum 4. For example, the control board 7 is used to: determine whether the actual temperature of the drum 4 is within the set temperature range; if the temperature inside the drum 4 exceeds the set temperature range, then reduce the air output of the air power source 1 to reduce the amount of heat absorbed by the air amplifier 2, thereby reducing the temperature inside the drum 4; if the temperature inside the drum 4 is lower than the set temperature range, then increase the air output of the air power source 1 to increase the amount of heat absorbed by the air amplifier 2, thereby increasing the temperature inside the drum 4. In this way, the temperature of the drum 4 can be maintained within the set working temperature, which will not waste air power energy or make the temperature inside the washing drum too high, thus reducing energy consumption. In addition, by controlling the temperature of the drum 4, the appropriate temperature inside the washing drum can be adjusted according to the type of clothes, thereby improving the drying effect.

[0049] The drying system 100 provided in this application embodiment amplifies the flow rate of the high-temperature airflow used to input the drum 4 by adding an air amplifier 2, which can increase the flow rate of the high-temperature air in the drum 4, accelerate the evaporation of moisture in the clothes to be treated in the drum 4, and thus improve the drying efficiency of the clothes.

[0050] This application also provides a clothes dryer, for example, please refer to [link to example]. Figure 5 , Figure 5This is a schematic diagram of the structure of a clothes dryer provided in an embodiment of this application. The clothes dryer 10 includes the drying system 100 in any of the above embodiments. The clothes dryer 10 can be a drying device with only drying function, or it can be a washer-dryer combo device with both washing and drying functions. In some embodiments, the clothes dryer 10 further includes a sterilization device (not shown) disposed at the output port 23, which is used to release bactericidal substances. In practical applications, the bactericidal substances released by the sterilization device enter the drum 4 with the high-temperature, high-speed airflow output by the air amplifier 2 to sterilize and deodorize the inside of the drum 4, thereby improving the drying and cleaning effect of the clothes. To provide users with a better user experience, a fragrance device can also be provided at the output port 23 or in the drum 4. The fragrance device is used to release fragrance substances into the drum 4 so that the clothes have a fragrance after drying.

[0051] The dryer provided in this application embodiment amplifies the flow rate of the high-temperature airflow used to input the drum by adding an air amplifier to the drying system. This increases the flow rate of the high-temperature air in the drum, accelerates the evaporation of moisture from the clothes to be processed in the drum, and thus improves the drying efficiency of the dryer.

[0052] The drying system and dryer provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
