[0035] In the related art, there are usually three drying methods for household clothes dryers, which are respectively:

[0036] Exhaust-type clothes dryer: It uses a heating device to convert electrical energy into heat energy, and sends the heat energy into the drum through the air duct system, so that the temperature in the drum rises to heat and evaporate the moisture in the wet clothes into water vapor, and then directly discharges the moisture into the atmosphere. This process is repeated continuously to dry the clothes.

[0037] Condensing clothes dryer: It uses a closed drying channel system to heat and evaporate the moisture in the wet clothes into water vapor, and condenses the water vapor in the clothes outside the drum into liquid water through a condensing device. This process is continuously circulated to dry the clothes.

[0038] Heat pump clothes dryer: The heat pump clothes dryer is an upgraded version of the condensing clothes dryer. It uses a compressor 1 to drive the refrigerant to carry the heat in the air, so that the condenser generates heat to evaporate the moisture in the clothes into water vapor; at the same time, it uses the cold released by the evaporator 5 to condense the water vapor.

[0039] The existing disadvantages of the above three drying methods are as follows: The exhaust-type clothes dryer needs to exhaust the drying waste gas, which causes serious environmental pollution; the condensing clothes dryer and the heat pump clothes dryer have very high production costs, and at the same time, the complex structure results in high later maintenance costs; the drying efficiency is low and the energy consumption is high, wasting energy. Moreover, the noise generated by the drying equipment of the above three methods is relatively large during the working process, affecting the user experience.

[0040] An embodiment of the present application provides a drying system and a drying device to solve the problem of relatively large noise generated during the operation of existing drying devices. The following will be described in conjunction with the attached Figures 1-5 illustrations (the arrow direction in the figure is the gas flow direction).

[0041] The drying system provided by the embodiment of the present application, as shown in Figure 1 Figure 9, includes a compressor 1, a vortex tube 2, a drying cylinder 3, and a sound insulation structure 4. The vortex tube 2 is connected to the compressor 1, and the vortex tube 2 is provided with a hot gas outlet 21; the drying cylinder 3 is connected to the hot gas outlet 21; the sound insulation structure 4 is installed on at least one of the compressor 1 and the vortex tube 2.

[0042] It can be understood that in this embodiment, vortex heating is a method of obtaining heating by using the action of the vortex tube 2 to make the high-speed air flow generate vortex separation of cold and hot air flows and using the hot air flow. The compressor 1 can compress air into high-pressure gas and transport the high-pressure gas to the vortex tube 2. After passing through the vortex tube 2, the high-pressure gas will generate cold air and hot air. The vortex tube 2 has a cold air outlet 22 and a hot air outlet 21. The cold air flows out from the cold air outlet 22, and the hot air flows out from the hot air outlet 21. The hot air outlet 21 is connected to the drying cylinder 3 to dry the objects in the drying cylinder 3.

[0043] The way of vortex heating can be realized by a pure mechanical structure, without electricity, without any chemical substances, and without the generation of electric sparks during use. It has a small volume, light weight, simple production and low cost, rapid refrigeration and heating. The air flow of the vortex tube 2 directly participates in energy conversion, with high drying efficiency, energy conservation and environmental protection, fast drying speed, and greatly improves the user experience.

[0044] Exemplarily, based on the working principle of the vortex tube 2, the lowest temperature of the cold air generated can reach -46°C, and the highest temperature of the hot air can reach 127°C, which can effectively meet the drying requirements of the objects to be dried.

[0045] In an optional embodiment, the number of vortex tubes 2 can be multiple, and the multiple vortex tubes 2 are arranged in parallel. The hot air outlets 21 of the multiple vortex tubes 2 are all connected to the inside of the drying cylinder 3, which can greatly improve the drying speed and drying efficiency.

[0046] Furthermore, in view of the relatively large noise that the compressor 1 and the vortex tube 2 may generate during the drying process, the drying system is provided with a sound insulation structure 4. The sound insulation structure 4 can reduce the noise of at least one of the compressor 1 and the vortex tube 2, which can greatly reduce the noise generated during the operation of the drying system and improve the user experience.

[0047] Exemplarily, the sound-absorbing structure 4 can be implemented in a variety of ways, such as wrapping the outer shell of the compressor 1 and the vortex tube 2 with sound-absorbing materials, or isolating the noise with a physical structure, or installing a shock absorber or a silencer on the compressor 1 and the vortex tube 2, etc., as long as it can achieve the effect of reducing noise.

[0048] The drying system provided in the embodiment of the present application includes a compressor 1, a vortex tube 2, a drying drum 3 and a muffler structure 4. The vortex tube 2 is connected to the compressor 1, and the vortex tube 2 is provided with a hot air outlet 21. The drying drum 3 is connected to the hot air outlet 21, and the muffler structure 4 is installed on at least one of the compressor 1 and the vortex tube 2. The compressor 1 provides high-pressure gas to the vortex tube 2, and the high-pressure gas can generate cold air and hot air after passing through the vortex tube 2. The hot air can dry the objects in the drying drum 3. At the same time, since the noise generated by the compressor 1 and the vortex tube 2 during operation is relatively large, by providing the muffler structure 4 to muffle and reduce the noise of at least one of the compressor 1 and the vortex tube 2, the noise generated by the drying system during operation can be greatly reduced, thereby improving the user experience.

[0049] According to one embodiment of the present application, referring to Figure 2 As shown, the muffler structure 4 includes a shielding cover, which can be arranged outside the vortex tube 2 and the compressor 1. The shielding cover can block or reduce the noise generated by the compressor 1 and the vortex finder from propagating to the outside. The shielding cover can be made of a high-density material with good sound absorption performance to effectively absorb and reflect noise and reduce the penetration of noise.

[0050] According to one embodiment of the present application, referring to Figure 1 , Figure 3 and Figure 4 As shown, the drying system also includes an evaporator 5, the vortex tube 2 is provided with a cold air outlet 22, the heat absorption channel of the evaporator 5 connects the cold air outlet 22 and the inlet of the compressor 1, and the heat release channel of the evaporator 5 connects the drying cylinder 3 and the inlet of the compressor 1.

[0051] In this embodiment, the vortex tube 2 separates the input compressed air into two parts through the vortex effect inside it. One part is cold air with a lower temperature, which is discharged through the cold air outlet 22, and the other part is hot air with a higher temperature, which is discharged through the hot air outlet 21. The heat absorption channel of the evaporator 5 is connected to the cold air outlet 22 of the vortex tube 2. The cold air generated by the vortex tube 2 is used to cool the evaporator 5. The heat release channel of the evaporator 5 is connected to the drying cylinder 3. The hot air can be mixed with the moisture in the drying cylinder 3 to become humid hot air. The humid hot air exchanges heat and cools down with the cold air in the heat release channel of the evaporator 5, and then enters the compressor 1 after merging with the cold air to form a circulation pipeline.

[0052] By utilizing the cold air generated by the vortex tube 2 and the heat exchange effect of the evaporator 5, effective condensation of moisture in the hot and humid air and heat recovery are achieved. By recovering heat and recycling gas, the demand for fresh air from the outside and energy consumption are reduced. The efficient heat exchange effect of the evaporator 5 accelerates the condensation and drying process of the hot and humid air in the drying cylinder 3, thereby shortening the drying time.

[0053] According to one embodiment of the present application, referring to Figure 3 As shown, a fan 6 is provided between the air outlet of the drying drum 3 and the evaporator 5 , and the fan 6 is used to drive the gas in the drying drum 3 to flow to the heat release channel of the evaporator 5 .

[0054] In this embodiment, the fan 6 generates airflow by rotating to extract the hot and humid gas in the drying cylinder 3 and flow it to the heat release channel of the evaporator 5. The fan 6 ensures the continuity and efficiency of the gas flow, thereby improving the efficiency of heat exchange. As the temperature of the hot and humid gas in the evaporator 5 decreases, the moisture therein will gradually condense into liquid water. The driving action of the fan 6 helps to speed up the condensation process, so that more moisture can be separated from the gas.

[0055] The working process of the drying system of this embodiment is as follows: the clothes are put into the drying drum 3, and the compressor 1 provides compressed air to the vortex tube 2; the vortex tube 2 separates the compressed air into cold air and hot air; the cold air is discharged through the cold air outlet 22 and connected to the heat absorption channel of the evaporator 5 for cooling; the hot air enters the drying drum 3 and mixes with the moisture in the drum to form humid hot gas, and the humid hot gas flows to the heat release channel of the evaporator 5 under the drive of the fan 6; the humid hot gas exchanges heat with the cold refrigerant in the evaporator 5, and the moisture condenses into liquid water, and the gas is cooled and dried at the same time. The treated gas merges with the cold air generated by the vortex tube 2, and the merged gas enters the compressor 1 for compression, and then enters the vortex tube 2 again for recycling.

[0056] According to one embodiment of the present application, referring to Figure 3 As shown, a filter 7 is arranged between the air outlet of the drying drum 3 and the heat release channel of the evaporator 5 .

[0057] In this embodiment, the filter 7 can effectively intercept fine debris such as clothing lint and thread scraps mixed in the gas discharged from the air outlet of the drying drum 3. If these debris enter the evaporator 5, they may adhere to the surface of the evaporator 5 or block the heat exchange channel, thereby reducing the heat exchange efficiency and even affecting the normal operation of the system. By providing the filter 7, the internal environment of the drying system can be kept clean, and it is also convenient for users to clean these debris regularly.

[0058] According to one embodiment of the present application, referring to Figure 4 and Figure 5As shown, a water collecting tank 8 is provided in the heat release channel of the evaporator 5 to collect the condensed water in the heat release channel.

[0059] It can be understood that when the humid and hot gas in the drying cylinder 3 passes through the evaporator 5 with a lower temperature, the moisture inside the humid and hot gas will condense into water droplets on the evaporator 5. By providing the water collecting tank 8, the water droplets condensed due to the temperature reduction when the humid and hot gas passes through the heat release channel can be collected, preventing the condensed water from accumulating inside the evaporator 5, avoiding the condensed water from hindering the heat exchange process, and ensuring the normal heat exchange of the evaporator 5.

[0060] Optionally, the water collecting tank 8 can be a water pipe communicating with the outside, and the condensed water can be directly discharged to the outside of the drying system to keep the evaporator 5 dry and clean.

[0061] In an optional embodiment, the number of the evaporators 5 can be multiple, and the multiple evaporators 5 are arranged in series to further reduce the moisture content in the humid and hot gas.

[0062] In an optional embodiment, refer to Figure 3 As shown, a first reverse flow valve 9 is provided between the heat release channel of the evaporator 5 and the outlet of the compressor 1, and the first reverse flow valve 9 is used to prevent the gas from flowing from the outlet of the compressor 1 to the heat release channel of the evaporator 5.

[0063] In an optional embodiment, refer to Figure 4 As shown, a second reverse flow valve 10 is provided between the heat absorption channel of the evaporator 5 and the inlet of the compressor 1, and the second reverse flow valve 10 is used to prevent the gas from flowing from the outlet of the compressor 1 to the heat absorption channel of the evaporator 5.

[0064] The first reverse flow valve 9 and the second reverse flow valve 10 can effectively prevent the gas from flowing back and unable to form a loop, ensure the normal operation of the drying system, reduce the drying time, and improve the drying efficiency.

[0065] According to an embodiment of the present application, refer to Figure 1 As shown, the drying system further includes a motor 11, and the motor 11 is connected to the drying cylinder 3 to drive the drying cylinder 3 to rotate. The rotation of the drying cylinder 3 enables the clothes or materials in the drying cylinder 3 to be continuously turned over, so as to ensure that the hot air can uniformly penetrate and dry every part, which helps the moisture on the surface of the clothes or materials to evaporate faster and improves the drying efficiency.

[0066] According to an embodiment of the present application, refer to Figure 3As shown, the vortex tube 2 is provided with a control valve 12, and the control valve 12 is configured to adjust the flow rate of the hot gas outlet 21 to adjust the outlet temperature of the hot gas outlet 21. By adjusting the opening degree of the control valve 12, the flow rate of the hot gas outlet 21 can be changed, thereby affecting the gas temperature of the hot gas outlet 21, so as to adjust the drying speed and adapt to the drying requirements of different clothes.

[0067] In an alternative embodiment, referring to Figure 1 As shown, the drying system may further include a controller 13, and the controller can control the operation of the entire drying system to facilitate user operation. Among them, the controller 13 can control the rotation speed of the air compressor 1 to adjust the air pressure; the controller 13 can control the rotation of the motor 11 to drive the drying cylinder 3 to rotate. For example, the controller 13 can adjust parameters such as the rotation direction, rotation time, and rotation speed of the motor 11; the controller 13 can also adjust the control valve 12 to adjust the air flow rate at the hot end of the vortex tube 2, so as to adjust the temperature of the hot and cold ends; the controller 13 can also control the rotation speed of the fan 6 to adapt to the drying environment required by different clothes.

[0068] In a second aspect, the embodiments of the present application further provide a drying device, and the drying device includes the drying system in the above embodiments.

[0069] It can be understood that the drying device in this embodiment may include, but is not limited to, household appliances such as a clothes dryer, a pulsator washing and drying machine, a drum washing and drying machine, a shoe washing machine, and a dishwasher.

[0070] It can be understood that if the drying system has the beneficial effects of the above embodiments, the drying device correspondingly has the beneficial effects of the above embodiments. The specific implementation manners may refer to the above embodiments, and will not be elaborated herein.

[0071] In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application.
