[0050] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0051] Please refer to Figure 1 The embodiment of the present application discloses a drying assembly, including a housing 100, a drum assembly 200 and a drying assembly 300. The drying device can be applied to a dryer to dry clothes and fabrics.

[0052] Among them, the shell 100 is the basic component of the drying device of the present application. The shell 100 can provide an installation base for at least some of the other components of the drying device and serve the purpose of including at least some of the other components. The shell 100 can adopt a metal structure, a composite material structure, or a structure combining metal, plastic and composite materials. The specific structure can be determined according to the actual needs of the user, that is, the weight is relatively light while ensuring that the shell 100 has good structural strength and corrosion resistance. There is a cavity in the shell 100, which can be used to accommodate and install at least some of the other components of the drying device. Specifically, the barrel assembly 200 is arranged in the cavity in the shell 100, and the drying assembly 300 is connected to the inner wall of the cavity of the shell 100, so that the barrel assembly 200 can be supported.

[0053] Please refer to Figure 2 The cylinder assembly 200 has a drying chamber 210, and the drying chamber 210 can be used by the user to accommodate objects to be dried, such as clothes, bed sheets, curtains and other objects. The drying assembly 300 is also arranged in the shell 100, and an air duct is arranged in the drying assembly 300. The air duct of the drying assembly 300 is connected with the drying chamber 210 of the cylinder assembly 200. The drying assembly 300 can generate dry and hot airflow and drive the dry and hot airflow into the drying chamber 210 of the cylinder assembly 200. After the dry and hot airflow contacts the objects to be dried in the cylinder assembly 200, the moisture of the objects can be brought out of the drying chamber 210, and the dry and hot airflow becomes a humid hot airflow. The humid hot airflow enters the air duct of the drying assembly 300 again, the moisture of the humid hot airflow is separated to form a dry hot airflow, and the dry hot airflow is heated again to increase the airflow temperature, and the regenerated dry and hot airflow enters the drying chamber 210 again. Therefore, the airflow output by the drying component 300 for drying objects always circulates between the air duct of the drying component 300 and the drying chamber 210, so that the heat of the airflow used to dry objects can be concentrated between the air duct and the drying chamber 210, thereby reducing the loss of heat of the airflow, allowing the heat of the airflow to be recovered, and ultimately making the drying device of the present application have a better drying effect.

[0054] Please refer to Figure 7 The housing 100 is provided with a take-in and take-out opening 110, which is provided on the surface of the housing 100. The take-in and take-out opening 110 of the housing 100 is communicated with the opening of the drying chamber 210 of the drum assembly 200. The user can put the object to be dried into the drying chamber 210 through the take-in and take-out the object that has been dried from the drying chamber 210 through the take-in and take-out opening 110. The take-in and take-out opening 110 of the housing 100 can be set to an openable and closable structure, so that when the drying assembly 300 outputs the airflow for drying the object into the drying chamber 210, the drying airflow can be prevented from overflowing. Specifically, an openable and closable door seal structure can be set on the housing 100, and the door seal structure is movably connected to the housing 100, and can be specifically a rotational connection, so that the door seal can block the take-in and take-out opening 110 of the housing 100, or open the take-in and take-out opening 110 of the housing 100.

[0055] It should be understood that when the objects to be dried, such as clothes, are placed in the drying chamber 210 of the drum assembly 200, the objects to be dried will be concentrated at the bottom of the drying chamber 210 under the action of their own gravity. In order to allow the dry and hot drying gas to fully contact the objects to be dried, the connecting portion 400 of the present application can be arranged between the drying assembly 300 and the drum assembly 200.

[0056] The drying component 300 of the present application is specifically provided with an air inlet 316 and an air outlet 321 that are connected to the internal air duct. The drying gas generated by the drying component 300 is discharged from the air outlet 321 and input into the drying chamber 210, and the gas in the drying chamber 210 is input into the drying component 300 through the air inlet 316. The connection part 400 also has a channel structure inside. Specifically, the connection part 400 is provided with an air guide 410. One end of the air guide 410 is connected to the air outlet 321 of the drying component 300, and the other end of the air guide 410 is connected to the drying chamber 210 in the barrel component 200. Therefore, the dry and hot drying gas output from the drying component 300 can enter the drying chamber 210 of the barrel component 200 through the air guide 410. The air outlet direction of the air duct 410 of the connecting portion 400 can be set to be away from the top of the drying chamber 210, that is, the air outlet of the air duct 410 is facing away from the top of the drying chamber 210, so that the dry and hot drying gas output through the air duct 410 can be flowed in a direction away from the top of the drying chamber 210, so that the dry and hot drying gas can be relatively concentrated in the bottom space of the drying chamber 210. The flow of the drying gas in a direction relatively toward the bottom of the drying chamber 210 can also make the drying gas blow directly toward the object to be dried, and can make the drying gas more fully contact with the object to be dried concentrated at the bottom of the drying chamber 210, thereby reducing the loss of the drying gas. Specifically, the flow direction of the drying gas output through the air duct 410 is as follows: Figure 2 The middle bend is shown by the solid line.

[0057] In the drying device proposed in the embodiment of the present application, both ends of the air duct of the drying component 300 are connected to the drying chamber 210 of the cylinder component 200, so that the drying component 300 can input dry and hot drying airflow into the drying chamber 210, and the moist and hot drying gas formed after the drying gas contacts the object to be dried can be circulated into the drying component 300, so that the drying gas can always circulate between the drying component 300 and the cylinder component 200, reducing the heat loss of the drying gas. The air outlet direction of the air duct 410 of the connecting part 400 is away from the top of the drying chamber 210, so that the dry and hot drying gas can be relatively concentrated at the bottom of the drying chamber 210 after being output through the air duct 410, so that the drying gas can fully contact the object to be dried at the bottom of the drying chamber 210, so that the drying effect of the drying device of the present application is better.

[0058] In some embodiments, in order to allow the drying gas to more fully contact the objects to be dried in the drying chamber 210, the connection between the air duct 410 of the connecting portion 400 and the drying chamber 210 can be set on the side of the drying chamber 210, so that the drying gas output by the air duct 410 enters the drying chamber 210 from the side of the drying chamber 210, and because the air outlet direction of the air duct 410 is away from the top of the drying chamber 210, the air outlet direction of the air duct 410 and the direction from the top to the bottom of the drying chamber 210 have an angle, so that the drying gas output by the air duct 410 can flow in the drying chamber 210 along a direction inclined to the top to the bottom of the drying chamber 210, so that the drying gas also has a speed in the direction of the line connecting the opposite side walls of the drying chamber 210, so that the drying gas has a wider range of flow in the drying chamber 210, and thus the drying gas can more fully contact and cover the objects to be dried in the drying chamber 210.

[0059] In some embodiments, it should be understood that after the object to be dried is placed in the drying chamber 210, the moisture of the object to be dried will diffuse in the drying chamber 210, so that a small amount of moisture is distributed in the top space of the drying chamber 210, and a large amount of moisture is concentrated in the bottom space of the drying chamber 210. In the present application, the connection between the air duct 410 of the connecting part 400 and the drying chamber 210 can be set at a position adjacent to the top of the drying chamber 210, so that the drying gas input into the drying chamber 210 through the air duct 410 can enter the drying chamber 210 from a position adjacent to the top of the drying chamber 210, and flow in a direction close to the bottom of the drying chamber 210 until it contacts the object to be dried concentrated at the bottom of the drying chamber 210. Therefore, the drying gas input into the drying chamber 210 through the air duct 410 can flow along the side adjacent to the top of the drying chamber 210 to the bottom side of the drying chamber 210, and can also flow from one side of the drying chamber 210 to the other side, and finally flow to the bottom side of the drying chamber 210. In this way, the drying gas has a larger flow range in the drying chamber 210, and can be in contact with moisture in various areas of the drying chamber 210, so that the drying gas can be dried in the drying chamber 210 while the drying chamber 210 as a whole can be in a dry state, which is conducive to more efficient drying of the objects to be dried.

[0060] In some embodiments, the barrel assembly 200 of the present application may be specifically configured to include an inner barrel 240 and an outer barrel 230, both of which are cylindrical structural members, wherein the inner barrel 240 is rotatably disposed in the outer barrel 230, and the outer barrel 230 is sleeved in the inner barrel 240, and the drying chamber 210 is disposed in the inner barrel 240. Therefore, after the drying gas is input into the drying chamber 210, the inner barrel 240 rotates relative to the outer barrel 230, so that the object to be dried in the inner barrel 240 can be turned over as the inner barrel 240 rotates, so that the drying gas can contact various parts of the surface of the object to be dried, so that the drying gas can contact the object to be dried more fully. In the present application, the drying chamber 210 may also be configured as a cylindrical structure, so that the cavity shape of the drying chamber 210 can match the outer shape of the barrel assembly 200, so as to fully utilize the space inside the barrel assembly 200 to form the drying chamber 210. The air duct 410 can pass through the outer cylinder 230 and communicate with the drying chamber 210 in the inner cylinder 240. The connection between the air duct 410 and the drying chamber 210 can be specifically located on the axial end side of the drying chamber 210, that is, the connection between the connecting part 400 and the cylinder assembly 200 is located on the axial end side of the cylinder assembly 200.

[0061] It should be understood that, in the case where the barrel assembly 200 is a cylindrical structure, the axial end face of the barrel assembly 200 is a plane, and the circumferential side face of the barrel assembly 200 is an arc surface. Therefore, in order to make the connection between the connecting portion 400 and the barrel assembly 200 more convenient, the connection between the connecting portion 400 and the barrel assembly 200 is set at the axial end of the barrel assembly 200 by a plane, so that the opening of the end where the connecting portion 400 and the barrel assembly 200 are connected can also be a plane opening, thereby reducing the difficulty of preparing and processing the connecting portion 400, making it convenient to connect and install the connecting portion 400 and the barrel assembly 200. Of course, it should also be noted that, in the case of the structural limitations of the drying device itself, the connection between the connecting portion 400 and the barrel assembly 200 can also be set at the circumferential side wall of the barrel assembly 200.

[0062] In some embodiments, reference Figure 2 In order to make the air outlet direction of the air duct 410 deviate from the top of the drying chamber 210, the air outlet direction of the air duct 410 can be specifically set to be set at an angle with the axis of the drying chamber 210 of the cylindrical structure, and the air outlet direction of the air duct 410 is specifically deviated from the axial direction of the drying chamber 210 toward the bottom of the drying chamber 210, so that the air outlet direction of the air duct 410 deviates from the top of the drying chamber 210. Specifically, the angle between the air outlet direction of the air duct 410 and the axis of the drying chamber 210 can be set to be less than 45 degrees, so that the drying airflow output by the air duct 410 can flow in the direction of the line connecting the opposite side walls of the drying chamber 210 for a relatively longer time. Specifically, the axis of the drying chamber 210 is as shown in FIG. Figure 2 As shown by the dotted line running through the drying chamber 210.

[0063] It should be understood that in the related art, when the objects to be dried are placed in the drying chamber 210, the objects to be dried are concentrated on the bottom side of the drying chamber 210. Therefore, the drying airflow needs to flow into the upper area of ​​the drying chamber 210 to prevent the drying airflow from being blocked by the objects to be dried accumulated in the drying chamber 210.

[0064] In the present application, the drying assembly 300 is arranged in the housing 100, so that the housing 100 can protect the drying assembly 300. At the same time, the drying assembly 300 is also arranged on the top of the barrel assembly 200, that is, in the present application, there is a gap between the top inner wall of the housing 100 and the barrel assembly 200, and the gap can be used for the installation of the drying assembly 300. When the drying assembly 300 fails and needs to be repaired, the housing 100 and the drying assembly 300 need to be disassembled. Therefore, when the drying assembly 300 is located at the top of the barrel assembly 200, that is, located in the upper area of ​​the housing 100, the maintenance personnel can disassemble the housing 100 and the drying assembly 300 in a relatively convenient and natural posture to perform maintenance and repair on the drying assembly 300. In addition, since the drying component 300 is arranged at the top of the barrel component 200, the distance between the drying component 300 and the top side of the barrel component 200 is smaller than other parts of the barrel component 200. In this way, the drying component 300 can be more conveniently connected to the top side of the barrel component 200, so that the connection structure between the drying component 300 and the barrel component 200 is less in amount and has a relatively simple structure, which can reduce the preparation cost of the drying device of the present application. In addition, it can also reduce the total length of the flow path of the drying airflow formed by the air duct and the drying chamber 210, and reduce the wind resistance encountered by the drying airflow during the flow, so that the drying airflow can circulate more efficiently between the air duct and the drying chamber 210, and ultimately make the drying efficiency of the drying device of the present application better.

[0065] In the drying device proposed in the embodiment of the present application, the barrel assembly 200 and the drying assembly 300 are both arranged in the housing 100, so that the drying device of the present application has a compact structure and a high degree of integration. The air duct in the drying assembly 300 is connected to the drying chamber 210 of the barrel assembly 200, so that the drying assembly 300 can input a drying airflow into the drying chamber 210, and the drying airflow can be circulated again to the drying assembly 300 after contacting the object to be dried, so that the heat of the drying airflow can be collected, reducing heat loss. The drying component 300 is arranged at the top of the barrel component 200, so that the installation position of the drying component 300 is relatively closer to the top side of the shell 100, so that maintenance personnel can easily disassemble and inspect the drying component 300. In addition, the drying component 300 is closer to the top of the barrel component 200, so that the drying component 300 can be easily connected to the top of the barrel component 200. In this way, the connection structure between the drying component 300 and the barrel component 200 is relatively simple and low in cost. At the same time, the flow path of the air flow path formed by the air duct of the drying component 300 and the drying chamber 210 of the barrel component 200 is relatively shorter, which can make the drying airflow circulate more efficiently between the barrel component 200 and the drying component 300. Ultimately, the drying device of the present application has a better drying effect.

[0066] In some embodiments, since the drying component 300 is arranged at the top of the cylinder component 200, the air duct in the connecting part 400 needs to extend from the top of the cylinder component 200 to the side of the cylinder component 200. Therefore, the air guide duct 410 in the connecting part 400 of the present application can be specifically set to include a first air guide section 411 and a second air guide section 412, wherein the first air guide section 411 and the second air guide section 412 are connected, and the air outlet direction of the first air guide section 411 can be set to be toward the bottom of the cylinder component 200, and the air outlet direction of the second air guide section 412 can be set to be away from the top of the drying chamber 210, and the angle between the air outlet direction of the second air guide section 412 and the axis of the drying chamber 210 is less than 45 degrees. Specifically, the extension direction of the first air guide section 411 can be set to be the same as the direction from the top to the bottom of the drying chamber 210, so that the drying gas output by the drying assembly 300 can flow to the cylinder assembly 200 more efficiently, and the second air guide section 412 can guide the drying gas output by the first air guide section 411, so that the drying gas output through the air guide duct 410 can finally be concentrated at the bottom of the drying chamber 210. Specifically, the first air guide section 411 can be extended in the vertical direction, and the second air guide section 412 is bent relative to the first air guide section 411, so that the flow direction of the drying gas can be changed.

[0067] In some embodiments, in order to allow the drying gas to more efficiently pass through the air guide 410 and enter the drying chamber 210, it can be arranged that in the extension direction of the second air guide section 412, the flow rate through the second air guide section 412 is gradually increased, so that the second air guide section 412 has a pressure diffusion structure, so that the drying gas can more efficiently pass through the second air guide section 412. Specifically, in the extension direction of the second air guide section 412, the area of ​​the cross section of the second air guide section 412 in its extension direction is set to gradually increase, which can be specifically manifested as the second air guide section 412 becoming thicker and thicker, so that the flow rate of the drying gas that can pass through the second air guide section 412 is gradually increased, so that the second air guide section 412 can play a role of pressure diffusion.

[0068] In order to make the second air guide section 412 have an outward expansion structure, in the extension direction of the second wind tunnel, the opposite inner walls of the second air guide section 412 can be arranged to extend in opposite directions, so that the width of the second air guide section 412 can be increased, so that the flow rate of the drying gas that can pass through the second air guide section 412 can be increased. Alternatively, the inner wall of one side of the second air guide section 412 has an outward expansion structure, which can also increase the flow rate of the drying gas that can pass through the second air guide section 412.

[0069] In some embodiments, in order to allow the drying gas to flow more smoothly from the first air guide section 411 to the second air guide section 412, the air guide duct 410 in the connecting portion 400 of the present application may also be specifically provided with a third air guide section 413. The third air guide section may be provided between the first air guide section 411 and the second air guide section 412, and the two ends of the third air guide section 413 are respectively connected to the air outlet end of the first air guide section 411 and the air inlet end of the second air guide section 412. The third air guide section 413 is bent relative to the first air guide section 411 and the second air guide section 412, and the air outlet direction of the third air guide section 413 is also set to face away from the top of the drying chamber 210. In this way, after the drying gas output by the first air guide section 411 enters the third air guide section 413, the flow direction of the drying gas has been changed to face away from the top of the drying chamber 210. After the drying gas further enters the second air guide section 412, the flow direction of the drying gas further deviates in the direction away from the top of the drying chamber 210. Therefore, by setting the third air guide section 413, the flow direction of the drying gas can change more naturally when flowing in the air guide duct 410, thereby reducing the wind resistance of the drying gas when flowing in the air guide duct 410, so that the drying gas can pass through the air guide duct 410 more efficiently.

[0070] The inner wall of the third air guiding section 413 may be configured as a curved surface structure, and the curved surface inner wall is configured to be concave toward the outside of the connecting portion 400 , thereby further reducing the wind resistance of the drying gas passing through the air guiding passage 410 .

[0071] In some embodiments, reference Figure 3 and Figure 4 In order to enable the air guide duct 410 to communicate with the drying chamber 210, the cylinder assembly 200 of the present application may also have an air inlet hole 241, and the air inlet hole 241 may be specifically arranged in the inner cylinder 240. Accordingly, the connecting portion 400 passes through the outer cylinder 230 to communicate with the air inlet hole 241 of the inner cylinder 240, or the connecting portion 400 is connected to the outer cylinder 230, and a hole-shaped structure is provided on the outer cylinder 230, so that the hole-shaped structure can constitute at least part of the second air guide section 412, that is, part of the air guide duct 410 is located in the connecting portion 400, and part of the air guide duct 410 is located in the outer cylinder 230.

[0072] The axial direction of the air inlet hole 241 provided in the inner cylinder 240 can be set to be the same direction as the air outlet direction of the air guide 410, so that at least part of the drying gas output through the air guide 410 can pass through the air inlet hole 241 into the drying chamber 210 without changing the flow direction, so that the drying gas can fully flow in the direction away from the top of the drying chamber 210, and further the drying gas can be concentrated in the bottom space of the drying chamber 210 after passing through the air inlet hole 241. In addition, in the process of the drying gas passing through the air inlet hole 241, the hole shape of the air inlet hole 241 can also further correct the flow direction of the drying gas, so that when the drying gas flows along the extension direction of the air inlet hole 241, its flow direction is further limited to the direction away from the top of the drying chamber 210.

[0073] In some embodiments, the number of the air inlet holes 241 of the drum assembly 200 of the present application can be set to multiple, and the multiple air inlet holes 241 can be arranged at intervals along the center of the axial side end surface of the inner drum 240, and the multiple air inlet holes 241 are also arranged at intervals along the radial direction of the axial side end surface of the inner drum 240, so that the multiple air inlet holes 241 can be arranged dispersedly around the center of the axial side end surface of the inner drum 240. It should be understood that since the inner drum 240 can rotate relative to the outer drum 230, the multiple air inlet holes 241 arranged in the inner drum 240 can also rotate with the inner drum 240, and since the axial direction of the air inlet holes 241 of the inner drum 240 has an angle with the axis of the drying chamber 210, the circumferential direction of the air inlet holes 241 will change due to the change in the position of the air inlet holes 241 during the process of the air inlet holes 241 rotating with the inner drum 240. Therefore, in the present application, when the air inlet hole 241 is rotated to be opposite to the air outlet direction of the air duct 410, the axial direction of the air inlet hole 241 is set to be in the same direction as the air outlet direction of the air duct 410, so that the drying gas output by the air duct 410 can still flow in a direction away from the top of the drying chamber 210 after passing through the air inlet hole 241.

[0074] In some embodiments, the barrel assembly 200 of the present application may be provided with a fourth air guide section 251, wherein one end of the fourth air guide section 251 may be connected to one end of the second air guide section 412 away from the third air guide section 413, and the other end of the fourth air guide section 251 may be connected to the air inlet hole 241, and the air outlet direction of the fourth air guide section 251 is also consistent with the air outlet direction of the second air guide section 412, so that the flow direction of the drying gas output through the second air outlet section can be further corrected after passing through the fourth air guide section 251.

[0075] Specifically, the drying device may be provided with a plurality of air guide plates 250, two air guide plates 250 may be provided on the axial end surface of the inner cylinder 240, and located on opposite sides of the air inlet hole 241, so that the air inlet hole 241 is located between the two air guide plates 250, and the gap between the two air guide plates 250 may constitute a fourth air guide section 251, and the extension direction of the two air guide plates 250 may be provided in the same direction as the air outlet direction of the second air guide section 412, so that the air outlet direction of the fourth air guide section 251 between the two air guide plates 250 is the same as the air outlet direction of the second air guide section 412.

[0076] In addition, it should be understood that the air outlet direction of the fourth air guide section 251 formed between the air guide plates 250 of the present application can also change after the inner cylinder 240 rotates. Therefore, when the air outlet direction of the fourth air guide section 251 is opposite to that of the second air guide section 412, the air outlet direction of the fourth air guide section 251 is the same as that of the second air guide section 412.

[0077] In some embodiments, please refer to Figure 8 The drying assembly 300 of the present application specifically includes a drying body 310 and a fan 320. The drying body 310, the fan 320 and the cylinder assembly 200 are connected end to end in sequence, so that the drying body 310, the fan 320 and the cylinder assembly 200 form a circulation system. The drying body 310 can heat the air to form dry hot drying gas, the fan 320 can act on the drying gas to make the drying gas flow to form a drying airflow, the fan 320 can input the drying airflow into the drying chamber 210, and input the gas in the drying chamber 210 into the drying body 310 again, so that the drying airflow can be circulated.

[0078] Specifically, in the present application, the air duct in the drying component 300 is arranged in the drying body 310 and the fan 320. Therefore, the drying component 300 and the fan 320 are independently connected to each other and are components with channels inside. The channel in the drying body 310 is connected with the channel inside the fan 320 to form the air duct of the drying component 300. In this way, when the drying component 300 and the fan 320 fail and need maintenance, the fan 320 and the drying component 300 can be easily disassembled and assembled, making the drying component 300 of the present application easy to maintain.

[0079] Of course, it should be understood that in other embodiments, the air duct of the drying component 300 can also be set to be located inside the drying body 310, and the fan 320 is set in the air duct inside the drying body 310, so that the fan 320 can be set as a rotatable fan blade, thereby making the drying component 300 more integrated and more compact.

[0080] In some embodiments, reference Figure 6 Figure 8 One end of the fan 320 is connected to the drying body 310, and the other end of the fan 320 is connected to the drying chamber 210 through the connecting part 400, and the end is the air outlet 321 of the drying component 300. Correspondingly, the end of the drying body 310 connected to the drying chamber 210 is the air inlet 316. Therefore, the fan 320 can suck out the drying gas in the drying body 310 and then input it into the drying chamber 210 of the cylinder assembly 200. In this way, the fan 320 can adopt a centrifugal fan, which has a better suction effect, so the drying gas in the drying body 310 can be more efficiently input into the drying body 310.

[0081] In some embodiments, reference Figure 3-Figure 5In order to enable the drying body 310 to have the function of heating dry air, the drying body 310 may specifically include an air duct box 311, a compressor 312, an evaporator 314 and a condenser 313. The air duct box 311 is a basic component of the drying body 310, and the air duct box 311 has a cavity structure inside. The air duct specifically includes a first air segment 315 and a second air segment connected to each other. The first air segment 315 is arranged in the air duct box 311, and the second air segment is arranged in the fan 320. The evaporator 314 and the condenser 313 are both arranged in the air duct box 311, and the compressor 312, the evaporator 314 and the condenser 313 are connected end to end in sequence. The pipes of the compressor 312, the evaporator 314 and the condenser 313 contain coolant, and the compressor 312 acts on the coolant to compress the coolant into a high-temperature and high-pressure state. A throttling device is also provided between the compressor 312, the condenser 313 and the evaporator 314. The evaporator 314 and the condenser 313 can be sequentially arranged in the first air section 315 along the direction from the air inlet 316 to the air outlet 321, so that the air passing through the first air section 315 can be heated to form dry hot gas after contacting the condenser 313, and the hot and humid gas after contacting the object to be heated in the drying chamber 210 can contact the evaporator 314 so that the moisture in the hot and humid gas can be cooled and precipitated, thereby reducing the humidity of the hot and humid gas. After the hot and humid gas contacts the condenser 313 again, the temperature of the gas is further increased and the humidity is further reduced. Specifically, the working principle of the system composed of the compressor 312, the evaporator 314 and the condenser 313 is similar to the air heating principle, and this application will not elaborate on this. The fan 320 drives the gas to circulate between the first air section 315 , the second air section and the drying chamber 210 , so that the gas can always circulate between the air duct and the drying chamber 210 .

[0082] In some embodiments, reference Fig. 9The compressor 312 and the fan 320 in the drying component 300 of the present application can be arranged relative to each other. Specifically, the compressor 312 is arranged outside the air duct box 311, so that the compressor 312 does not need to occupy the space in the air duct box 311, and the compressor 312 will not cause additional resistance to the gas flowing in the first air section 315 of the air duct box 311. The compressor 312 and the fan 320 can be distributed on the opposite sides of the air duct box 311, so that the compressor 312 and the fan 320 and the space on the opposite sides of the air duct box 311 are utilized, so that the compressor 312 and the fan 320 are dispersedly arranged, so that the compressor 312 and the fan 320 can be arranged close to the air duct box 311, so that the structure of the drying component 300 is compact. Specifically, the pipeline of the compressor 312 can pass through the air duct box 311 and connect to the condenser 313 and the evaporator 314 in the air duct box 311, so that the length of the pipeline connecting the compressor 312 with the condenser 313 and the evaporator 314 is relatively short, so that the coolant can circulate more efficiently between the compressor 312, the condenser 313 and the evaporator 314. The fan 320 is arranged close to the air duct box 311, so that the length of the pipeline between the fan 320 and the air duct box 311 can be relatively shorter, so that the total length of the air duct can be relatively short, and finally the drying gas can circulate more efficiently in the air duct and the drying chamber 210.

[0083] In some embodiments, reference Fig. 9 The air duct box body 311 specifically includes a top cover 311a, and a first side wall 311b and a second side wall 311c that are arranged on both sides of the air duct box body 311 and are opposite to each other. The first side wall 311b and the second side wall 311c are the outer walls of the air duct box body 311. The direction from the first side wall 311b to the second side wall 311c is the first direction. The direction from the bottom to the top of the shell 100, that is, the height direction when the shell 100 is placed on a horizontal plane is the second direction. The first direction and the second direction intersect, and specifically, the first direction and the second direction are perpendicular. Therefore, the fan 320 and the compressor 312 can be distributed on both sides of the air duct box body 311 in the horizontal direction, so that the height dimension of the drying component 300 is relatively low, and then the overall height dimension of the drying device of the present application is relatively small, which is conducive to the installation of the drying device.

[0084] In addition, in other embodiments, the fan 320 and the compressor 312 can also be distributed on the adjacent side walls of the air duct box body 311, and the adjacent side walls are adjacent side walls distributed on the circumferential side of the air duct box body 311. In this way, the fan 320 and the compressor 312 can also fully utilize the space around the air duct box body 311 when they are installed, so that the fan 320 and the compressor 312 can also achieve the purpose of dispersed setting, and the fan 320 and the compressor 312 can still be set close to the air duct box body 311, so that the structure of the drying component 300 is compact.

[0085] In some embodiments, reference Figure 2 and Figure 6 It should be understood that the barrel assembly 200 in the present application may be a cylindrical structure, so the circumferential outer wall of the barrel assembly 200 is a curved surface. When the barrel assembly 200 is disposed in the housing 100, the circumferential side wall of the barrel assembly 200 facing the top of the housing 100 is the top side curved wall 220. The top center of the barrel assembly 200 is at a relatively shortest distance from the top side inner wall of the housing 100, that is, the distance between the middle part of the top side curved wall 220 and the top side inner wall of the housing 100 is the shortest. Correspondingly, the distance between the two side areas of the top side curved wall 220 and the top side bottom wall of the housing 100 is relatively large. Therefore, the space between the middle part of the top side curved wall 220 and the top side inner wall of the housing 100 is relatively small, and the space between the two side parts of the top side curved wall 220 and the top side inner wall of the housing 100 is relatively large.

[0086] In order to enable the fan 320, the compressor 312 and the air duct box body 311 to fully utilize the space between the shell 100 and the barrel assembly 200, the fan 320, the air duct box body 311 and the compressor 312 are specifically distributed along the circumferential direction of the outer wall of the barrel assembly 200, and the air duct box body 311 can be specifically arranged in the space between the middle part of the top side arc wall 220 of the barrel assembly 200 and the top side inner wall of the shell 100, and the air duct box body 311 can adopt a relatively flat structure, so that the air duct box body 311 can be adapted to the relatively small space between the middle part of the top side arc wall 220 and the top side inner wall. The volume of the fan 320 and the compressor 312 is larger than that of the air duct box body 311, so the fan 320 and the compressor 312 can be respectively arranged in the space between the two side parts of the top side arc wall 220 and the top side inner wall. In this way, the fan 320 and the compressor 312 can utilize the relatively large space between the two side parts of the top side arc wall 220 and the top side inner wall, so that the distance between the fan 320 and the compressor 312 and the top side inner wall is closer to the distance between the air duct box body 311 and the top side inner wall. In this way, the overall height of the drying device of the present application can be controlled to avoid the height of the drying device being too high.

[0087] In some embodiments, in order to further make the structure of the drying device of the present application compact and the internal space can be fully utilized, the fan 320 can be vertically arranged in the housing 100. Specifically, the fan 320 includes a fan housing and a fan blade, the fan housing is a shell structure with a cavity inside, the second wind section is specifically located in the fan housing, the fan housing has an air inlet and an air outlet, the air inlet of the fan housing is connected to the first wind section 315 of the air duct box 311, the air outlet of the fan housing is connected to the drying chamber 210 of the barrel assembly 200, and the fan blade is rotatably arranged in the fan housing, and the rotation of the fan blade can inhale the gas in the first wind section 315 through the air inlet and discharge it through the air outlet. The fan blade can be arranged opposite to the air inlet, so that after the fan blade rotates, the gas in the first wind section 315 can be efficiently inhaled, so that the efficiency of gas passing through the second wind section is higher. Moreover, the axis of the fan blade and the axis of the air inlet are both toward the first side wall 311b of the air duct box 311, so that the fan blade can be vertically arranged in the shell 100, so that the fan 320 as a whole can be a vertically long structure. Therefore, the fan 320 can be arranged in the gap space between the barrel assembly 200 and the inner top wall of the shell 100, and the lateral space occupied by the fan 320 in the shell 100 is relatively small, so that the width dimension of the drying device of the present application is more compact.

[0088] In some embodiments, the fan 320 of the present application may specifically adopt a centrifugal fan, and therefore, the fan housing is a volute structure, the air inlet of the fan housing may be arranged on the axial side of the fan housing, and the air outlet of the fan housing may extend along the circumference of the fan housing, so that the fan 320 may be further compact in structure when vertically arranged in the housing 100, and finally the drying device of the present application may be compact in structure. In addition, the compressor 312 may specifically adopt a horizontal rotor compressor, and the rotor compressor has better compression performance, and the horizontal compressor has the characteristic of a smaller height dimension, so the length direction of the compressor 312 of the present application may be distributed along the axis of the barrel assembly 200, so that the space in the height direction of the housing 100 occupied by the compressor 312 is less.

[0089] In some embodiments, in order to fix the drying assembly 300 of the present application in the housing 100, the drying assembly 300 can be specifically connected to the housing 100, so that the housing 100 can support the drying assembly 300. It should be understood that the compressor 312 and the fan 320 in the drying assembly 300 will generate vibrations during operation. By connecting the drying assembly 300 to the housing 100, the vibrations generated by the drying assembly 300 can be transmitted to the housing 100, and the vibration energy can be absorbed by the housing 100.

[0090] In the present application, the barrel assembly 200 may specifically include an outer barrel and an inner barrel, wherein the outer barrel may be connected to the inner wall of the housing 100 so that the outer barrel is fixed in the housing 100, the inner barrel may be arranged in the outer barrel, the inner barrel may rotate in the outer barrel, and the drying chamber 210 is located in the inner barrel. As the inner barrel rotates, the objects to be dried, such as clothes, in the drying chamber 210 may rotate accordingly, so that the clothes are fully spread out, so that the drying airflow can fully contact the clothes, so that the clothes are fully dried. The inner barrel may be specifically mounted in the outer barrel, a connecting shaft supporting the inner barrel may be arranged in the outer barrel, and a gap may be arranged between the inner barrel and the outer barrel, so that the inner barrel can smoothly rotate relative to the outer barrel. In the present application, there is also a gap between the drying assembly 300 and the barrel assembly 200, so that the vibration generated by the drying assembly 300 will not be directly transmitted to the barrel assembly 200, thereby reducing the influence of the vibration of the drying assembly 300 on the operation of the barrel assembly 200, so that the inner barrel can rotate smoothly.

[0091] In some embodiments, reference Figure 8 The drying assembly 300 of the present application may be specifically configured to include a support base 330, wherein the support base 330 is a basic component of the drying assembly 300, and the support base 330 may provide a mounting base for at least some other components of the drying assembly 300. Specifically, the air duct box 311 and the compressor 312 may be disposed on the support base 330, and the edge end of the support base 330 may be connected to the inner wall of the housing 100, so that the support base 330 may be fixed in the housing 100. The fan 320 may also be disposed on the support base 330, so that the support base 330 may also play a role in supporting the fan 320. Of course, the fan 320 may also be connected to the air duct box 311, so that the air duct box 311 supports the fan 320, and then the fan 320 is fixedly installed. The specific installation method of the fan 320 is not limited when the fan 320 is not in direct contact with the cylinder assembly 200.

[0092] In some embodiments, reference Figure 6In order to make the air duct box 311 and the fan 320 have a gap with the barrel assembly 200 when the second air section in the fan 320 and the first air section 315 in the air duct box 311 are both connected to the drying chamber 210 of the barrel assembly 200, the drying device of the present application further includes a flexible tube 500, wherein the two ends of the flexible tube 500 are respectively connected to the air duct box 311 and the drying chamber 210 of the barrel assembly 200. The connecting part 400 and the flexible tube 500 are both flexible pipes, so when the vibration generated by the operation of the drying assembly 300 is transmitted to the connecting part 400 and the flexible tube 500, the connecting part 400 and the flexible tube 500 can absorb the vibration energy of the drying assembly 300 and block the vibration energy of the drying assembly 300 from continuing to be transmitted. The connecting part 400 and the flexible tube 500 can also be provided with a redundant section, so that the connecting part 400 and the flexible tube 500 can more fully absorb the vibration energy generated during the operation of the drying assembly 300.

[0093] In some embodiments, reference Figure 7 In order to make the support base 330 in the present application stably connected to the housing 100, the support base 330 is specifically provided with a first connection 331 and a second connection 332 connected to the housing 100, so that the support base 330 and the housing 100 have multiple connections, thereby making the connection effect of the support base 330 and the housing 100 stable and reliable. The first connection 331 and the second connection 332 can be specifically distributed on the opposite sides of the support base 330, so that the support base 330 can maintain a relatively stable balance. Specifically, the direction from the first connection 331 to the second connection 332 is a third direction, and the third direction intersects with both the first direction and the second direction. Specifically, the third direction is perpendicular to both the first direction and the second direction, so that the connection between the support base 330 and the housing 100 can be relatively far away from the fan 320 and the compressor 312, so as to reduce the influence of the vibration of the compressor 312 and the fan on the first connection 331 and the second connection 332, and finally make the connection effect of the support base 330 and the housing 100 stable and reliable.

[0094] In some embodiments, reference Figure 7 and Fig. 9It should be understood that the air duct of the present application has an air inlet 316 and an air outlet 321, and the air inlet 316 and the air outlet 321 of the air duct are both connected to the drying chamber 210 of the barrel assembly 200. The drying airflow output by the drying assembly 300 can be input into the drying chamber 210 through the air outlet 321. After the drying airflow contacts the object to be dried, the airflow with moisture can circulate back to the drying assembly 300 through the air inlet 316. The air inlet 316 and the air outlet 321 of the air duct can be distributed at a side of the access opening 110 adjacent to the housing 100, and correspondingly, the air outlet of the air duct can be arranged at a position away from the access opening 110 of the housing 100, so that the air inlet 316 and the air outlet 321 of the air duct can be distributed at relatively far positions on the barrel assembly 200, so that the drying gas discharged through the air outlet 321 and entering the drying chamber 210 can fully flow in the drying chamber 210 and then enter the drying assembly 300 through the air inlet 316. The range of the drying airflow flowing through the drying chamber 210 is larger, and the drying airflow contacts the objects to be dried in the drying chamber 210 more fully, so that the objects to be dried can be dried more efficiently.

[0095] Of course, it should be understood that in other embodiments, the air inlet 316 and the air outlet 321 of the air duct in the present application can also be arranged on both sides of the access port 110 of the shell 100, so that the air inlet 316 and the air outlet 321 can be relatively dispersed, so that the drying airflow can fully pass through the drying chamber 210.

[0096] In some embodiments, reference Figure 5It should be understood that when the drying object of the drying device of the present application is clothes and other objects, the lint of the clothes will be scattered in the drying chamber 210 and circulate into the air duct along with the drying airflow. If the lint accumulates on the evaporator 314, the condenser 313 and the fan 320 and other components, it will affect the working performance of these components, and even cause damage to these components. Therefore, the drying device of the present application is also provided with a filter assembly 600, which can be arranged at the air inlet 316, and the drying airflow can flow back into the air duct box body 311 through the filter assembly 600. The lint and other debris will be blocked by the filter assembly 600 outside the air inlet 316, so that the lint cannot enter the air duct box body 311, thereby preventing the lint from accumulating on the condenser 313, the evaporator 314 and the fan 320. In addition, under the drive of the drying airflow, the fluff and other debris can be close to the filter assembly 600, so that the fluff can be attached to the filter assembly 600, so that the fluff can be concentrated on the filter assembly 600, so as to facilitate the centralized treatment of the fluff. When the amount of fluff accumulated on the filter assembly 600 is too much and affects the drying airflow passing through the filter assembly 600, the filter assembly 600 can be removed from the housing 100 to facilitate cleaning of the fluff and debris accumulated on the filter assembly 600. After the filter assembly 600 is cleaned, the filter assembly 600 can be installed at the air inlet 316, so that the filter assembly 600 can be used multiple times.

[0097] Specifically, the air duct box body 311 of the present application may have an opening at a position adjacent to the air inlet 316, and the shell 100 may have an opening corresponding to the opening of the air duct box body 311, so that the filter component 600 can be installed in the air duct box body 311 at a position adjacent to the air inlet 316 in a plug-in manner through the above-mentioned two openings, thereby achieving the purpose of making the filter component 600 detachably arranged at the air inlet 316.

[0098] In some embodiments, it should be understood that when the drying device is placed in an indoor environment, the drying component 300 can be placed close to the wall. Specifically, the access port 110 of the shell 100 faces away from the wall, so that the user can put the object to be dried through the access port 110, and the outer wall of the shell 100 opposite to the access port 110 can be against the wall. Therefore, in order to allow the user to easily disassemble and assemble the filter component 600, the air duct inlet 316 can be arranged adjacent to the access port 110 of the shell 100, and the air outlet 321 of the air duct can be arranged away from the access port 110 of the shell 100. In this way, the installation position of the filter component 600 is relatively far away from the wall, so that the user can conveniently operate the filter component 600.

[0099] Specifically, the shell 100 has a top side surface, and the top side surface of the shell 100 is located at the top of the shell 100. The disassembly and assembly port of the shell 100 is opened on the top side surface of the shell 100, so that the user can easily observe the installation position of the filter assembly 600 to disassemble and assemble the filter assembly 600.
