[0065] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0066] Please refer to Figure 1 The embodiment of the present application discloses a drying device, including a housing 100, a drum assembly 200 and a drying assembly 300. The drying device can be applied to a drying machine to dry clothes and fabrics.

[0067] 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.

[0068] Please refer to Figure 2The 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.

[0069] Please refer to Figure 3 The shell 100 is provided with a first access opening 110, which is provided on the surface of the shell 100. The first access opening 110 of the shell 100 is communicated with 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 first access opening 110, or take out the dried object from the drying chamber 210 through the first access opening 110. The first access opening 110 of the shell 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 shell 100, and the door seal structure is movably connected to the shell 100, and can be specifically a rotational connection, so that the door seal can block the first access opening 110 of the shell 100, or open the first access opening 110 of the shell 100.

[0070] The drying component 300 of the present application is specifically provided with three openings connected to the air duct inside the drying component 300, and the three openings are all connected to the drying chamber 210 of the barrel component 200. Among them, the three openings include at least one air inlet and air outlet, and 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 hot and humid gas in the drying chamber 210 after contacting with the object to be dried can be input into the drying component 300 through the first air inlet 316, and the hot and humid gas is heated and dried in the drying component 300 to form dry hot gas, and the dry hot gas can be circulated into the drying chamber 210 again to dry the object to be dried. Since the drying component 300 has an opening in addition to the air inlet and the air outlet, the drying airflow can also circulate between the drying component 300 and the drying chamber 210 through the opening, thereby improving the efficiency of the drying airflow circulating between the drying component 300 and the drying chamber 210.

[0071] In the drying assembly 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 structure of the drying device of the present application is compact and highly integrated. The air duct in the drying assembly 300 is connected with 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 into the drying assembly 300 after contacting the object to be dried, so that the heat of the drying airflow can be collected and the heat loss can be reduced. In addition to being connected with the drying chamber 210 through the air inlet and the air outlet, the drying assembly 300 is also connected with the drying chamber 210 through an opening, so that the drying airflow circulates more efficiently between the drying assembly 300 and the drying chamber 210, and the flow rate of the drying airflow circulating between the drying assembly 300 and the drying chamber 210 is larger, and finally the drying device of the present application has a better drying effect on the object to be dried.

[0072] In some embodiments, the three openings of the drying component 300 may be specifically configured to include an air outlet 321, a first air inlet 316, and a second air inlet 317, wherein the dry and hot drying airflow after drying and heating in the drying component 300 may be discharged through the air outlet 321 and input into the drying chamber 210 of the drum component 200, and the humid and hot drying airflow formed after the dry and hot drying airflow contacts the object to be dried may be circulated into the drying component 300 through the first air inlet 316 and the second air inlet 317. By providing the first air inlet 316 and the second air inlet 317 on the drying component 300, the humid and hot drying airflow may be more efficiently circulated back into the drying component 300, thereby reducing the time that the humid and hot drying airflow stays in the drying chamber 210, so that the humid and hot drying airflow may be more efficiently circulated back into the drying component 300, so as to prevent the moisture of the humid and hot drying airflow from being retained in the drying chamber 210 to a certain extent, and at the same time, the wind resistance of the drying airflow in the process of returning to the drying component 300 may be reduced.

[0073] Of course, it should be understood that in other embodiments, the three openings of the drying component 300 of the present application can also be set to include an air inlet and two air outlets 321. This can reduce the wind resistance of the dry and hot drying gas in the drying component 300 flowing in the drying component 300, so that the dry and hot drying gas in the drying component 300 can be more efficiently input into the drying chamber 210 of the drum component 200, and ultimately the purpose of making the drying effect of the drying device of the present application better can be achieved.

[0074] In some embodiments, reference Figure 1 and Figure 2 In order to allow the hot and humid drying gas in the drying chamber 210 of the drum assembly 200 to circulate more efficiently into the drying assembly 300, the first air inlet 316 and the second air inlet 317 may be arranged adjacent to each other. Specifically, the second air inlet 317 may be arranged close to the first air inlet 316, and the corresponding second air inlet 317 may be arranged away from the air outlet 321. It should be understood that in order to allow the drying airflow to fully flow through the drying chamber 210, the connection between the air outlet 321 and the first air inlet 316 and the drying chamber 210 may be arranged on two relatively distant sides of the drying chamber 210, so that the drying gas can pass through the drying chamber 210 completely, so that the drying gas can contact the objects to be dried in the drying chamber 210 more fully. When the first air inlet 316 and the second air inlet 317 are arranged close to each other, the drying air flow in the concentrated area within the drying chamber 210 can flow back to the drying component 300 through the first air inlet 316 and the second air inlet 317 respectively. In this way, whether it is the drying gas entering the drying chamber 210 through the air outlet 321 and being discharged to the outside of the drying chamber 210 through the first air inlet 316, or the drying gas entering the drying chamber 210 through the air outlet 321 and being discharged to the outside of the sub-drying chamber 210 through the second air inlet 317, both can fully flow through the drying chamber 210, so that the drying gas can fully contact with the object to be dried.

[0075] In some embodiments, the air outlet 321 and the first air inlet 316 of the drying component 300 may be disposed on opposite sides of the barrel component 200. It should be understood that in the present application, the air outlet 321 and the first air inlet 316 of the drying component 300 are openings that connect the drying component 300 with the drying chamber 210 of the barrel component 200. The locations of the air outlet 321 and the first air inlet 316 determine the location where the drying airflow enters the drying chamber 210 and the location where the drying airflow is discharged from the drying chamber 210. The air outlet 321 and the first air inlet 316 are disposed on opposite sides of the barrel component 200 so that the air outlet 321 and the first air inlet 316 can be disposed relatively far apart, and the drying airflow can fully pass through and penetrate the drying chamber 210 in the barrel component 200, so that the drying airflow is in full contact with the objects to be dried. The second air inlet 317 can be specifically arranged on the side of the cylinder assembly 200, and the second air inlet 317 is located between the first air inlet 316 and the air outlet 321, so that the first air inlet 316 and the second air inlet 317 can be distributed and arranged at different parts of the cylinder assembly 200, so that the first air inlet 316 and the second air inlet 317 can make full use of the surface area of ​​the cylinder assembly 200, thereby making the openings of the first air inlet 316 and the second air inlet 317 can be set relatively larger, and finally making the efficiency of the drying gas in the drying chamber 210 to reflux to the drying assembly 300 higher.

[0076] In some embodiments, the barrel assembly 200 of the present application may specifically adopt a cylindrical structure, and accordingly, the drying chamber 210 in the barrel assembly 200 may also be in the shape of a cylindrical cavity. The barrel assembly 200 has a first end side and a second end side in its axial direction, and the air outlet 321 of the drying assembly 300 may specifically communicate with the first end side of the barrel assembly 200, and the first air inlet 316 of the drying assembly 300 may specifically communicate with the second end side of the barrel assembly 200, so that the air outlet 321 and the first air inlet 316 are distributed on opposite sides of the barrel assembly 200, and accordingly, the second air inlet 317 of the drying assembly 300 may communicate with the circumferential side wall of the barrel assembly 200, so that the second air inlet 317 is between the air outlet 321 and the first air inlet 316. After being discharged from the air outlet 321 of the drying component 300, the drying air flow can enter the barrel component 200 from the first end side of the barrel component 200, flow in the drying chamber 210 along the axial direction of the barrel component 200, and finally be discharged from the second end side of the barrel component 200, and discharged from the side wall of the barrel component 200 close to the second end side, so that the drying gas can fully pass through the drying chamber 210.

[0077] Of course, in other embodiments, the air outlet 321 and the first air inlet 316 of the drying component 300 of the present application can also be arranged on the opposite side walls of the barrel component 200 in its circumferential direction, so that the air outlet 321 and the first air inlet 316 can be arranged relatively far apart, and accordingly, the second air inlet 317 can be arranged at the end of the barrel component 200.

[0078] In some embodiments, the barrel assembly 200 of the present application may also have a second access opening 230, wherein the second access opening 230 of the barrel assembly 200 is connected to the drying chamber 210, and the second access opening 230 may be specifically arranged at the second end side of the barrel assembly 200, and the second access opening 230 may also be arranged opposite to the first access opening 110, so that the user can access the objects to be dried in the drying chamber 210 of the barrel assembly 200 through the first access opening 110. It should be understood that the first access opening 110 of the housing 100 is specifically an openable and closable structure, and after the first access opening 110 is closed, the drying airflow can be prevented from overflowing through the first access opening 110 of the housing 100, and after the first access opening 110 is opened, the user can access the objects to be dried through the first access opening 110.

[0079] In some embodiments, reference Figure 4 and Figure 5 The barrel assembly 200 of the present application can be specifically configured to include an inner barrel 240 and an outer barrel 250, both of which are cylindrical structural members, wherein the inner barrel 240 is rotatably arranged in the outer barrel 250, and the outer barrel 250 is sleeved in the inner barrel 240, and the drying chamber 210 is arranged 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 250, 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. There is a gap between the outer cylinder 250 and the inner cylinder 240, so that the outer wall of the inner cylinder 240 does not contact the inner wall of the outer cylinder 250 to generate resistance during the rotation of the inner cylinder 240. The gap between the outer cylinder 250 and the inner cylinder 240 can constitute an air transfer chamber 260 in the cylinder assembly 200. The air transfer chamber 260 is connected to the drying chamber 210, and the air outlet 321 and the second air inlet 317 of the drying assembly 300 are both connected to the air transfer chamber 260.

[0080] The dry hot drying gas output by the drying component 300 can enter the air transfer chamber 260 through the air outlet 321, and then be input into the drying chamber 210 from the air transfer chamber 260. Correspondingly, part of the moist hot drying gas in the drying chamber 210 can enter the air transfer chamber 260 and flow back to the drying component 300 through the second air inlet 317, so that the drying gas can circulate.

[0081] In some embodiments, in order to enable the drying chamber 210 in the inner cylinder 240 to communicate with the air transfer chamber 260, the inner cylinder 240 may specifically open a first air port 241 and a second air port 242, and the first air port 241 and the second air port 242 are openings opened on the surface of the inner cylinder 240 and passing through the outer wall of the inner cylinder 240. The dry and hot drying gas input into the air transfer chamber 260 by the drying component 300 can be input into the drying chamber 210 through the first air port 241, and part of the humid and hot drying gas in the drying chamber 210 can be discharged into the air transfer chamber 260 through the second air port 2423, and flow back to the drying component 300 through the second air inlet 317.

[0082] The first air port 241 of the inner cylinder 240 can be arranged adjacent to the air outlet 321, so that the hot and dry drying gas discharged through the air outlet 321 can more easily enter the drying chamber 210 through the first air port 241, and the second air port 242 of the inner cylinder 240 can be arranged adjacent to the second air inlet 317, so that the hot and humid drying gas discharged through the second air port 241 can more easily flow back to the drying component 300 through the second air inlet 317.

[0083] Specifically, since the air outlet 321 of the drying component 300 is arranged adjacent to the first end side of the barrel component 200, the first air outlet 241 of the inner barrel 240 can be arranged at the first end side of the inner barrel 240, so that the first air outlet 241 and the air outlet 321 are arranged adjacent to each other; since the second air inlet 317 of the drying component 300 is connected to the side of the barrel component 200, the second air outlet 242 can be arranged on the side of the inner barrel 240 between the first end side and the second end side, so that the second air outlet 242 and the second air inlet 317 are arranged adjacent to each other.

[0084] In some embodiments, it should be understood that the drying gas input into the air transfer chamber 260 through the second air port of the inner cylinder 240 is in a humid and hot state. In order to dehumidify the humid and hot drying gas more efficiently, the drying device of the present application may also be provided with a water cooling part 800, wherein the water cooling part 800 may be provided in the cylinder assembly 200, and the water cooling part 800 may spray water-cooling liquid, and specifically, the water cooling part 800 may spray water-cooling liquid into the air transfer chamber 260, so that the water-cooling liquid may contact with the humid and hot drying gas, and the moisture in the drying gas may be liquefied into liquid by contact with the water-cooling liquid, and the liquid may fall to the bottom of the outer cylinder 250 under the action of its own gravity. Therefore, when the hot and humid drying gas discharged from the second air outlet is in the air transfer chamber 260, at least part of the moisture in the drying gas can be removed, so that the humidity of this part of the drying gas is reduced. In this way, after this part of the drying gas flows back to the drying component 300 for processing, the drying gas can be relatively drier, so that the humidity of the drying gas finally output by the drying component 300 is lower, thereby achieving a better drying effect on the object to be dried.

[0085] The water cooling part 800 of the present application can be specifically arranged in the air transfer cavity 260, so that the output end of the water cooling part 800 can be located in the air transfer cavity 260, and the relevant pipelines of the water cooling part 800 can pass through the outer tube 250 to be connected with other components. Setting the water cooling part 800 in the air transfer cavity 260 can effectively utilize the space in the air transfer cavity 260, so that the structure of the drying device of the present application is more compact.

[0086] In some embodiments, the drying device of the present application may also be provided with a door seal, which may be provided at the second access port 230 of the cylinder assembly 200, and the door seal may be connected to the cylinder assembly 200. The door seal may also be specifically a circular structure, and the door seal may be connected to the edge of the second access port 230 of the cylinder assembly 200. When the door panel of the shell 100 is opened and closed, the door seal may prevent the mask from directly hitting the cylinder assembly 200, thereby protecting the cylinder assembly 200 through the airway. The door seal may be specifically made of rubber material, and the door seal may have a cavity connected to the drying chamber 210, and the cavity may also be connected to the first air inlet 316.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] In some embodiments, please refer to Figure 6-Figure 11 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. Specifically, 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, 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 first 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 component 200. In this way, the fan 320 can use a centrifugal fan. The centrifugal fan has a better suction effect, so the drying gas in the drying body 310 can be more efficiently input into the drying body 310.

[0091] 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.

[0092] 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.

[0093] In some embodiments, in 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 first 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 .

[0094] In some embodiments, the compressor 312 and the fan 320 in the drying assembly 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 does 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 assembly 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.

[0095] In some embodiments, the air duct box body 311 specifically has a top cover 311a, and a first side wall 311b and a second side wall 311c disposed on both sides of the air duct box body 311 and 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 housing 100, that is, the height direction when the housing 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 assembly 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.

[0096] 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.

[0097] In some embodiments, 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 arc wall 220. The top center of the barrel assembly 200 is at a relatively shortest spacing between the top side inner wall of the housing 100, that is, the spacing between the middle portion of the top side arc wall 220 and the top side inner wall of the housing 100 is the shortest. Correspondingly, the spacing between the two side regions of the top side arc wall 220 and the top side bottom wall of the housing 100 is relatively large. Therefore, the space between the middle portion of the top side arc wall 220 and the top side inner wall of the housing 100 is relatively small, and the space between the two side portions of the top side arc wall 220 and the top side inner wall of the housing 100 is relatively large.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] In the present application, the drum assembly 200 may specifically include an outer drum 250 and an inner drum 240, wherein the outer drum 250 may be connected to the inner wall of the housing 100 so that the outer drum 250 is fixed in the housing 100, the inner drum 240 may be arranged in the outer drum 250, the inner drum 240 may rotate in the outer drum 250, the drying chamber 210 is located in the inner drum 240, as the inner drum 240 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 drum 240 may specifically be mounted in the outer drum 250, a connecting shaft supporting the inner drum 240 may be arranged in the outer drum 250, and a gap may be arranged between the inner drum 240 and the outer drum 250, so that the inner drum 240 can smoothly rotate relative to the outer drum 250. In the present application, there is also a gap between the drying component 300 and the barrel component 200, so that the vibration generated by the drying component 300 will not be directly transmitted to the barrel component 200, thereby reducing the impact of the vibration of the drying component 300 on the operation of the barrel component 200, allowing the inner barrel 240 to rotate smoothly.

[0103] In some embodiments, 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. For the specific installation method of the fan 320, when the fan 320 is not in direct contact with the cylinder assembly 200, there is no restriction.

[0104] In some embodiments, in 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 first flexible tube 400, a second flexible tube 500 and a third flexible tube 700, wherein the two ends of the first flexible tube 400 are respectively connected to the fan 320 and the drying chamber 210 of the barrel assembly 200. 0, the two ends of the second flexible tube 500 are respectively connected to the air duct box body 311 and the drying chamber 210 of the drum assembly 200, the third flexible tube 700 is also connected to the drying assembly 300 and the drum assembly 200, and the two ends of the first flexible tube 400 are respectively connected to the fan 320 and the drying chamber 210, the two ends of the second flexible tube 500 are respectively connected to the first air inlet 316 and the drying chamber 210, and the two ends of the third flexible tube 700 are respectively connected to the second air inlet 317 and the drying chamber 210. The first flexible tube 400 and the second flexible tube 500 are both flexible pipes, so when the vibration generated by the operation of the drying assembly 300 is transmitted to the first flexible tube 400 and the second flexible tube 500, the first flexible tube 400 and the second 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 first flexible tube 400 and the second flexible tube 500 may also be provided with redundant sections, so that the first flexible tube 400 and the second flexible tube 500 may more fully absorb the vibration energy generated during the operation of the drying assembly 300 .

[0105] In some embodiments, 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.

[0106] In some embodiments, it should be understood that the air duct of the present application has a first air inlet 316 and an air outlet 321, and the first 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, and 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 carrying moisture can circulate back to the drying assembly 300 through the first air inlet 316. The first air inlet 316 and the air outlet 321 of the air duct can be distributed at one side of the first access opening 110 adjacent to the housing 100, and correspondingly, the air outlet of the air duct can be arranged at the first access opening 110 away from the housing 100, so that the first 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 first air inlet 316. The drying airflow has a larger flow range in the drying chamber 210, 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.

[0107] Of course, it should be understood that in other embodiments, the first 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 first loading and unloading port 110 of the shell 100, so that the first 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.

[0108] In some embodiments, it 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 first 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 first 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 first air inlet 316, so that the filter assembly 600 can be used multiple times.

[0109] Specifically, the air duct box body 311 of the present application may have an opening at a position adjacent to the first 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 first 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 first air inlet 316.

[0110] 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 first access port 110 of the shell 100 faces away from the wall, so that the user can put the to-be-dried items through the first access port 110, and the outer wall of the shell 100 opposite to the first 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 first air inlet 316 of the air duct can be arranged adjacent to the first access port 110 of the shell 100, and the air outlet 321 of the air duct can be arranged away from the first 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.

[0111] Specifically, refer to Fig.12The 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 120 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.
