Description

Washer-dryers are especially suitable for families in the south during the rainy season, families in the north where the air quality is poor and it is not suitable for outdoor drying of clothes, and people who want to wear clothes immediately after washing or pursue more fluffy and comfortable clothes.

[0003] The drying systems of some existing washer-dryers utilize an evaporator to heat and absorb moisture from the humid air in the washer-dryer's inner drum. The resulting high-temperature air then re-enters the drum, evaporating the moisture from the clothing. However, the overall temperature of the evaporator is consistent, and during the evaporation of the humid air, the evaporator's ability to absorb moisture from the humid air decreases, resulting in low moisture absorption efficiency, long drying times, and high power consumption. Others use condensate spraying or a condenser to directly dehumidify the humid airflow. However, the treated airflow still carries a high percentage of moisture, and recycling requires heating, cooling, dehumidification, and then heating the airflow again, resulting in low dehumidification efficiency and high power consumption.

[0068] At present, the airflow that has been dehumidified in the existing technology still carries a high proportion of moisture, and recycling requires heating the airflow - cooling it for dehumidification - and then heating it again, resulting in low dehumidification efficiency and high power consumption.

[0069] To solve the above problems, as shown in Figure 1, an embodiment of the present invention provides a drying module, including: a drying module connected to the drum of the washer-dryer, and a circulation module 3 outputs the wet circulating airflow from the drum to the dehumidification module 1 for dehumidification; a dehumidification module 1, which is respectively connected to the circulation module 3 and the drum, and the dehumidification module 1 is used to adsorb moisture from the wet circulating airflow from the drum so that the dry circulating airflow is output to the drum; a regeneration module 2, which is installed on the shell of the dehumidification module 1, and the regeneration module 2 is connected to the dehumidification module 1 so that the dry regeneration airflow is output to the dehumidification module 1, so as to desorb at least a part of the moisture from the dehumidification module 1 and restore its moisture adsorption capacity; a condensing module 4, which is connected to the regeneration air outlet of the regeneration module 2, and is used to condense the regeneration airflow output by the regeneration module 2 to form a low-temperature dry regeneration airflow; wherein the dehumidification module 1 is respectively connected and fixed to the circulation module 3 and the condensing module 4 to form an integrated module.

[0070] In this embodiment, the drying module is used to dry the wet airflow, which we define as the regeneration airflow; wherein, the circulation module 3 is used as the power for the airflow to circulate between the drum and the dehumidification module 1. The circulation module 3 transports the wet circulating airflow from the drum to the dehumidification module 1 for moisture absorption treatment. The dehumidification module 1 absorbs moisture from the wet circulating airflow from the drum so that the dry circulating airflow is output to the drum. The regeneration module 2 is connected to a portion of the dehumidification module 1 so that the dry regeneration airflow is output to this portion of the dehumidification module 1 to desorb moisture from at least a portion of the dehumidification module 1 and restore its moisture absorption capacity; the condensation module 4 is connected to the regeneration air outlet of the regeneration module 2 and is used to condense the regeneration airflow output by the regeneration module 2 to form a low-temperature dry regeneration airflow; the condensed water formed during the condensation process is discharged. The dehumidification module 1, circulation module 3 and condensation module 4 are independent modules. The dehumidification module is respectively connected and fixed to the circulation module 3 and condensation module 4 to form an integrated module, which is convenient for disassembly and assembly on the rack, and can also be used as a separate device to dry the air.

[0071] In one embodiment of the present invention, as shown in Figures 2 and 10 , the drying module includes overlapping portions 50 disposed around the perimeter of the integrated module for securing the integrated module to the frame. Specifically, at least one overlapping portion 50 is provided on each of the dehumidification module 1 , the circulation module 3 , and the condensing module 4 to ensure uniform force distribution across the integrated module.

[0072] The dehumidification module 1 comprises a dehumidification module upper shell and a dehumidification module lower shell; the regeneration module 2 comprises a regeneration module upper shell and a regeneration module lower shell; the circulation module 3 comprises a circulation module upper shell and a circulation module lower shell; and the condensing module 4 comprises a condensing module upper shell and a condensing module lower shell. The dehumidification module lower shell, the regeneration module lower shell, the circulation module lower shell, and the condensing module lower shell are integrally formed into a drying module lower shell; and the overlapping portion 50 is provided at least on the drying module lower shell. In this technical solution, the integrally formed drying module lower shell has good sealing properties and can provide a certain amount of support for the drying module. Therefore, the entire drying module can be overlapped on the frame by simply providing overlapping portions 50 on the four edges of the drying module lower shell.

[0073] Dehumidification module 1, regeneration module 2, circulation module 3, and condensing module 4 are fixedly connected to the frame. Therefore, the air inlet and outlet ports on the housings of these four modules can be fixed. A flexible connection is required between circulation module 3 and the drum to prevent damage due to the different amplitudes and frequencies of vibration between the drum and the frame.

[0074] In one embodiment of the present invention, the dehumidification module 1 includes an air outlet channel, one end of which is connected to the dehumidification module 1 and the other end of which is connected to the drum through a first corrugated hose.

[0075] In this embodiment, a first corrugated hose connects the dehumidification module 1 to the interior of the drum, preventing damage to the circulating air outlet duct and the dehumidification module 1 due to the drum's rotation. The circulating air outlet duct serves as a channel for the dry airflow, obtained by absorbing moisture from the rotor module, to enter the drum. Optionally, a filter assembly is provided in the drum outlet duct to filter the airflow entering the dehumidification module from the drum.

[0076] In one embodiment of the present invention, the dehumidification module 1 further includes: an air inlet channel, which can be installed on the drum, one end of which is connected to the drum, and the other end of which is connected to the circulation module 3. Furthermore, the dehumidification module further includes: a filter assembly provided in the circulating air inlet channel, for filtering impurities in the circulating air flow. A filter assembly (which can be a filter screen) is provided in the circulating air inlet channel to remove impurities in the circulating air flow, to prevent lint and dust impurities from entering the circulation module 3 and the dehumidification module 1, and to thereby avoid the occurrence of phenomena such as blockage of the above modules or combustion of impurities. Lint and dust impurities come from the drum, therefore, installing the circulating air inlet channel on the drum is conducive to directly filtering the circulating air flow, and to avoid blockage of the circulating air inlet channel and the circulation module 3.

[0077] In one embodiment of the present invention, the regeneration module 2 includes: a regeneration module upper shell 210 having a heating module 21 accommodating cavity;

[0078] The heating module 21 is installed in the heating module accommodating cavity. The heating module 21 is arranged adjacent to the turntable 100 in the dehumidification module, and the heating module 21 accommodating cavity is connected to the dehumidification module 1; the heating module 21 is used to desorb moisture from at least a portion of the turntable 100 by heating; the regeneration fan 22 is installed on the regeneration fan 22 mounting portion and is connected to the condensing module, and is used to transport the low-temperature dry regeneration airflow formed by condensation of the condensing module 4 to the heating module 21; the heating module 21 heats a portion of the dehumidification module 1 to evaporate the moisture adsorbed thereon, and the regeneration fan 22 transports the wind to the heating module 21 to form a high-temperature regeneration airflow, thereby accelerating the recovery of the moisture adsorption capacity of the dehumidification module 1.

[0079] In one embodiment of the present invention, the heating module 21 includes: a heater installed in a first space; a heat conductor 250 for receiving heat transferred from the first space; a temperature detection module for detecting the temperature of the first space; the temperature detection module is installed in a third space, which is a space formed by the heat conductor 250 and is separated from the first space by the heat conductor 250; an air distribution member, which is adjacent to or spaced apart from the turntable in the dehumidification module; the regeneration air flow enters the heating module accommodating chamber and passes through the air distribution member / heater, the heater / air distribution member, and the turntable 100 in sequence. It is understandable that the heat conductor 250 can completely isolate the first space from the third space, so that no gas exchange occurs between them; or an opening can be provided on the heat conductor 250, so that the first space and the third space can partially exchange gas, and the temperature detection module determines the temperature of the first space by detecting the temperature of the heat conductor 250.

[0080] The temperature detection module is used to detect the temperature of the heating area, including the temperature required for the clothing or intermediate medium to be heated and dehumidified. The heating module 21 includes a heater, and a power source is provided to circulate the airflow in the first space after being heated by the heater to remove moisture from the intermediate medium to be dehydrated. The intermediate medium here can be, for example, a turntable 100. The turntable 100 can be made of a material with good hygroscopic properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X type) molecular sieve, so that the moisture adsorbed by the turntable 100 can be dehydrated and dried by the heated airflow. During the rotation of the turntable 100, at least a portion continuously absorbs moisture, and at least another portion continuously dehydrates and dries, so that the turntable 100 is desorbed immediately after absorbing moisture, and this cycle can be repeated for reuse. The airflow in the first space in this embodiment of the present invention can be defined as a regeneration airflow.

[0081] In this embodiment, as shown in Figures 3 and 4, the heating module 21 includes a heater and a temperature detection module. The heater is disposed in the first space, and the temperature detection module is used to detect the temperature of the first space. The temperature detection module is installed in the third space, and a heat conductor 250 covers the temperature detection module. The heat conductor 250 transfers the heat received from the first space to the temperature detection module in the third space, thereby measuring the temperature of the regeneration airflow in the first space. The heat conductor 250 can be made of a metal material that easily conducts heat, such as copper or aluminum. The heat conductor 250 receives heat from the high-temperature regeneration airflow in the second space and transfers it to the temperature detection module in the third space. This can even out the heat transfer, making the temperature detected by the temperature detection module more stable, thereby improving the accuracy of the detection results. This prevents the temperature detection module from directly detecting the regeneration airflow in the first space, which may be turbulent or / and turbulent, causing the detection results to fluctuate frequently.

[0082] Heat conductor 250 is installed in the second space, which is connected to the first space. The second space is separated from the third space by heat conductor 250. The regeneration airflow is heated by the heater in the first space, turning it into high-temperature regeneration airflow. Since the second space is connected to the first space, the high-temperature regeneration airflow diffuses into the second space. Therefore, the temperature in the first space can be determined by measuring the temperature of the second space.

[0083] In one embodiment of the present invention, as shown in Figure 5, the regeneration module upper shell 210 includes a base 214, a top wall 212 and a side wall 213 protruding from the top wall 212. The top wall 212 and the side wall 213 are arranged to form a first space. The base 214 is arranged along the four sides of the side wall 213, and the base 214 extends outward away from the first space; the bottom surface of at least a portion of the base 214 is provided with a groove, and the groove forms a second space.

[0084] Specifically, the heating module 21 is used to heat the regeneration airflow and use the high-temperature regeneration airflow to remove moisture adsorbed on the turntable 100. The top wall 212 and side walls 213 of the regeneration module upper housing 210 enclose a first space, within which the heater is installed. The bottom surface of the base 214 is provided with a groove, within which the heat conducting member 250 is installed, enclosing the temperature detection module.

[0085] In one embodiment of the present invention, as shown in Figure 6 , the regeneration module upper housing 210 has a fan-shaped structure. A heater air inlet 211 is provided on the outer arc side of the regeneration module upper housing 210 , and a heater air outlet is provided on the side opposite the top wall 212 . The heater air inlet 211 , the first space, and the heater air outlet are sequentially connected. The base 214 includes a first side extending radially along the fan shape, with the groove located on the first side. For more accurate detection, a similar groove can be provided on a second side opposite the first side, and a temperature detection module can be positioned therein.

[0086] Specifically, the regeneration airflow enters through the heater inlet 211, is heated by the heater within the first space, and finally flows out through the heater outlet. A groove is located on the first side and communicates with the first space. The heated, high-temperature regeneration airflow diffuses into the groove, where the heat is transferred from the heat conductor 250 to the temperature detection module. This prevents the temperature detection module from being directly blown by the regeneration airflow flowing within the first space, thus reducing fluctuations in the detection results caused by turbulence.

[0087] In one embodiment of the present invention, the heating module 21 further includes a mounting base 218, which is fixedly connected to the first side, and the mounting base 218 is located on the other side of the first side away from the groove; the mounting base 218 is provided with a through mounting hole, forming a roughly hexahedral shape with one side open, the temperature detection module is arranged inside the mounting hole, and the space formed by the heat conductive member 250 covering the open surface of the mounting base 218 is the third space; the mounting hole is adapted to the temperature detection module. Specifically, the temperature detection module is installed in the mounting hole and is covered by the heat conductive member 250, so that the temperature detection module is isolated from the second space to avoid leakage of the regeneration airflow. A fixing member can be provided on the mounting base 218, and the fixing member can be used to fix the cable connected to the temperature detection module.

[0088] Furthermore, the heat conductor 250 contacts the contacts of the temperature detection module. The regeneration airflow circulating in the first space may be turbulent / turbulent, and the temperature of the regeneration airflow is unstable in a local area. Optionally, a ridge structure is provided on the side of the heat conductor 250 facing the second space to increase the contact area with the high-temperature regeneration airflow and extend the conduction path, so that the temperature conducted to the temperature detection module tends to a stable average. The heat conductor 250 can be set as a heat conductive sheet, which is easy to shape to cover the temperature detection module. For example, a protrusion can be provided on the side of the heat conductor 250 facing the second space, and a recess can be provided on the other side corresponding to the heat conductor 250. The temperature detection module can be embedded in the recess, and the contacts of the temperature detection module contact the recess. In this way, the contact area between the heat conductor 250 and the regeneration airflow is increased by the protrusion.

[0089] In one embodiment of the present application, as shown in FIG. 7 , the base 214 is connected to the mounting portion via a thermal buffer 270 .

[0090] In the drying module of the above embodiment, a thermal buffer 270 is provided between the heating module 21 and the upper housing of the dehumidification module. This buffers the heat generated by the heating module 21, preventing the high temperature from being directly transferred to the upper housing of the dehumidification module and damaging it. This delays aging of the upper housing of the dehumidification module and increases the service life of the drying module.

[0091] In this embodiment, the upper shell of the dehumidification module that accommodates the turntable 100 is an integrated and divided upper shell of the dehumidification module. The upper shell of the dehumidification module is provided with a moisture absorption area and a dehumidification area. The moisture absorption area and the dehumidification area are divided into at least two functional areas by at least two radial ribs. The mounting portion of the heating module 21 is provided in the dehumidification area of ​​the upper shell of the dehumidification module to facilitate the modular assembly of the heating module 21. The shape of the heating module 21 is adapted to the shape of the dehumidification area. If the upper shell of the dehumidification module is a circular structure, the dehumidification area is a fan-shaped area; then the heating module 21 is a fan-shaped structure, including a space formed by upper and lower walls and two side walls along the radial direction. A base and a heating element located below the base are provided in the space, and a thermostat mounting portion extends outward from one side wall of the lower wall. The base is provided with air holes. Wind passes through the air inlet of the heating module 21 and blows radially across the base. It then flows downward from the air holes through the heating element and onto the rotor portion of the moisture absorption zone, thereby heating and desorbing moisture from the rotor portion of the moisture absorption zone. The heating element is positioned immediately adjacent to the base to prevent significant resistance to wind passing through the air holes. The heating element is located directly below the air holes and slightly offset in the radial direction. This is because as wind blows inward along the radius and through the air holes, it will have a radial velocity in the direction indicated by the arrow. Therefore, this slight offset allows the wind passing through the air holes to directly face the heating element.

[0092] In some embodiments, the thermal buffer 270 includes: a thermal insulation member 271;

[0093] The heat insulating member 271 is provided on the peripheral side of the base to prevent the high temperature of the heating element from being directly transferred to the upper shell of the dehumidification module.

[0094] In this embodiment, the thermal insulation 271 is positioned around the base, between the heating module 21 and the dehumidification module upper housing. This insulation 271 blocks the heat generated by the heating module 21, preventing the high temperatures generated by the heating module 21 from being directly transferred to the dehumidification module upper housing, thereby preventing damage to the upper housing. This slows down the aging of the dehumidification module upper housing and increases the service life of the drying module.

[0095] In some embodiments, the thermal insulation member 271 is made of a thermal insulation material or a metal material.

[0096] In this embodiment, thermal insulation material is a general term for heat-insulating and cold-insulating materials. Its properties may include: low thermal conductivity; stable material properties with a clear thermal conductivity equation and a wide temperature range; low density; resistance to vibration and mechanical strength; good chemical stability and non-corrosiveness; good water resistance and low hygroscopicity. It should contain few flammable components and be self-extinguishing and non-flammable. To reduce costs, metal materials, such as hardware, may also be used. Hardware not only provides a certain degree of insulation, but also has a long service life and good thermoplasticity.

[0097] In some embodiments, the thermal buffer 270 further includes: a sealing gasket 272;

[0098] The sealing gasket 272 is covered on the outside of the thermal insulation member 271; or the sealing gasket 272 is respectively arranged on both sides of the thermal insulation member 271, that is, the heating module 21, the sealing gasket 272, the thermal insulation member 271, the sealing gasket 272, and the dehumidification module upper shell are arranged in sequence; or the sealing gasket 272 is only arranged between the thermal insulation member 271 and the dehumidification module upper shell.

[0099] In this embodiment, the sealing gasket 272 can be arranged along the thermal insulation member 271. In order to further prevent heat dissipation, the heat can be transferred along a predetermined path, while ensuring efficient use of heat and preventing heat from damaging the upper shell of the dehumidification module and other modules.

[0100] In some embodiments, the sealing gasket 272 is made of foam material, silicone material or soft rubber material.

[0101] In this embodiment, the material of the sealing gasket 272 is selected from relatively soft and elastic materials, which can be changed along with the structural changes of the heat insulating component 271 and can further increase the airtightness of the dehumidification area.

[0102] In some embodiments, a preset gap is left between the location where the sealing gasket 272 is set and the bottom of the mounting portion.

[0103] In this embodiment, a certain preset gap is left to reduce the resistance between the drying module and other modules. For example, a rotating wheel can be set under the drying module. If the sealing gasket 272 is in full contact with the rotating wheel, the rotation resistance of the rotating wheel will increase, which will not only affect the rotation of the rotating wheel, but also reduce the service life of the rotating wheel.

[0104] In some embodiments, the preset gap is 0.2-5 mm.

[0105] In this embodiment, a preferred preset gap range is provided. Within this range, the sealing gasket 272 will not contact adjacent components or modules, while also providing a certain sealing effect and preventing heat dissipation. After repeated research and experiments, the preset gap is controlled at 0.6-0.8mm, which has achieved good results.

[0106] In one embodiment of the present invention, the surface of the heat conducting member 250 has a heat-resistant and anti-corrosion coating to increase the service life of the heat conducting member 250 and prevent the heat conducting member 250 from rusting in a high temperature and humid environment.

[0107] The heating module 21 is installed in the heating module 21 receiving chamber. The heating module 21 is located above the turntable 100, and the heating module 21 receiving chamber is in communication with the turntable 100. The heating module 21 is used to heat the regeneration airflow to desorb moisture adsorbed by the turntable 100. In some embodiments, the turntable 100 components may include the turntable 100 and a drive assembly. The drive assembly may include a motor that drives the turntable 100 to rotate. The turntable 100 can be made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X) molecular sieve. The wet circulating airflow discharged from the drum enters the bottom of the turntable 100 accommodating cavity, and the wet circulating airflow in the dehumidification zone passes through the turntable 100 from bottom to top. The turntable 100 absorbs moisture in the wet circulating airflow, so that the wet circulating airflow can be turned into a dry circulating airflow. The dry circulating airflow enters the drum through the drum air inlet and fully contacts with the clothes, thereby improving the drying efficiency and reducing energy consumption. The regeneration component may include a heater for heating the regeneration airflow. The heated regeneration airflow passes through the heating module 21 accommodating cavity and passes through the turntable 100 from top to bottom to dehydrate and dry the turntable 100 part in the regeneration zone. During the rotation process, the turntable 100 circulates through the dehumidification zone and the regeneration zone, which is a process of continuously adsorbing and desorbing moisture. In this way, the dry circulating airflow can be continuously obtained to enter the drum, fully contact with the clothes, improve the drying efficiency and reduce energy consumption.

[0108] Specifically, the upper shell 210 of the regeneration module may include: a first top wall and a first side wall protruding around the first top wall to form a accommodating cavity for the heating module 21, and a base 214 protruding outward along the first side wall. The base 214 may be provided with a mounting hole, which can be connected and fixed to the upper shell 110 of the turntable 100 through the mounting hole.

[0109] In some embodiments, as shown in Figure 8, in order to make the incoming regeneration airflow heated more evenly and dehydrate and dry the turntable 100 more evenly, the preferred solution is that the heating module 21 includes a stacked air balancing member and a heater, and the heater is located between the air balancing member and the turntable 100; the regeneration airflow enters the accommodating cavity of the heating module 21, and passes through the air balancing member, the heater and the turntable 100 in sequence. The air balancing member can be set upstream or downstream of the heater. Of course, the upstream is the better choice. The air balancing member will guide the airflow flowing into the heater accommodating space so that the regenerated airflow can fully transfer the heat of the heater to the turntable 100. At this time, the heater is closer to the turntable 100, and the air balancing member is spaced relative to the turntable 100; the air balancing member can also be set downstream of the heater. The benefit at this time is that the regenerated airflow first fully contacts the heater, so that the regenerated airflow is heated evenly, and then the hot airflow is guided to the turntable 100 through the guidance of the air balancing member. In this case, the air balancing member is adjacent to the turntable 100, and the heater is spaced apart from the turntable 100. In addition to uniform airflow and guidance, the air balancing member can also protect the heating tube of the heater to a certain extent; the air balancing member can also be omitted, and the regenerated airflow flows directly to the turntable 100 after passing through the heater. At this time, cost can be saved and the complexity of the mechanism can be reduced.

[0110] In some embodiments, the regeneration module upper housing 210 has a fan-shaped structure; the outer arc side of the regeneration module upper housing 210 is provided with a heater air inlet 211. In the embodiments of the present invention, the preferred solution is that the regeneration module upper housing 210 has a fan-shaped structure; the regeneration module upper housing 210 may also have an irregular structure, which is not further limited herein; the regeneration module upper housing 210 is connected to the upper housing 110 of the turntable 100, thereby separating the dehumidification zone and the regeneration zone. That is, the wet circulating airflow in the dehumidification zone and the regeneration airflow in the regeneration zone are largely isolated.

[0111] In some embodiments, a gap is created between the air distribution element and the top wall of the regeneration module upper housing 210 to form a third airflow channel; this third airflow channel communicates with the heater air inlet 211. A gap is created between the bottom surface of the turntable 100 and the inner wall of the regeneration zone of the turntable 100 lower housing 120 to form a fourth airflow channel. The regeneration airflow enters the third airflow channel through the heater air inlet 211. The air distribution element ensures more uniform contact between the regeneration airflow and the heater. This evenly heated regeneration airflow desorbs moisture from the portion of the turntable 100 within the regeneration zone.

[0112] In some embodiments, the air distribution member includes an air distribution plate 230 and side panels protruding from the air distribution plate 230. The air distribution plate 230 and the side panels enclose a heater accommodation area, and the heater is located within the heater accommodation area. The air distribution plate 230 is fan-shaped and has air holes 231 spaced apart at intervals. The arrangement of the air holes allows the regeneration airflow to enter the heater below more evenly.

[0113] In some embodiments, the heater includes multiple heating tubes 240 connected end-to-end. The heating tubes 240 are spaced apart along the radius of the sector. The length of the heating tubes 240 is arranged approximately perpendicular to the radius of the sector. The S-shaped distribution of the heating tubes 240 allows the heating tubes 240 to be distributed longer within the heater housing area, thereby increasing the contact area with the regeneration airflow and improving the efficiency of heat exchange with the regeneration airflow.

[0114] In some embodiments, the air holes are arranged in rows, with the location of each row of air holes roughly corresponding to the location of the heater tube 240. The diameter of the air holes decreases along the radius of the fan-shaped circle from the outer arc to the center. The heater air inlet 211 is located on the outer arc side of the regeneration module upper housing 210. The diameter of the air holes is relatively larger near the heater air inlet 211, and relatively smaller away from the heater air inlet 211.

[0115] In some embodiments, the heating tube 240 is located below the air holes; the axis of the heating tube 240 is offset from the centerline of each row of air holes, with the centerline of each row of air holes being closer to the heater air inlet 211 than the axis of the heating tube 240. The heating tube 240 is located below the air holes, adjacent to the air balancing plate 230, or in other words, directly adjacent to the air balancing plate 230, so as not to create significant resistance to the regeneration airflow passing through the air holes. The heating tube 240 can be secured to the air balancing plate 230 using a pipe clamp, and a certain gap can be provided between the heating tube 240 and the air balancing plate 230 to allow the regeneration airflow to pass through. When the regeneration airflow enters the heater air inlet 211 and blows inward along the radius of the fan, it will have a velocity along the direction of the regeneration airflow. Therefore, setting a slight offset between the centerline of each row of air holes allows the regeneration airflow passing through the air holes to face the heating tube 240 directly, thereby achieving higher heat exchange efficiency between the regeneration airflow and the heating tube 240.

[0116] In some embodiments, the regeneration module upper housing 210 is fan-shaped; heater air inlets 211 are provided on the sidewalls of the regeneration module upper housing 210, arranged radially along the fan shape. The direction in which the regeneration airflow enters the heating module 21 housing cavity is opposite to the rotation direction of the turntable 100. This means that the regeneration airflow flows from the fan-shaped regeneration module in a direction generally perpendicular to the radius of the regeneration module into the heater housing cavity, either along or against the rotation direction of the turntable 100. This allows the airflow to be more evenly heated by the heater.

[0117] In some embodiments, the heater includes a plurality of heating tubes 240 connected end to end, spaced radially along a sector. The length of the heating tubes 240 is parallel to the side wall opposite the heater air inlet 211. Of course, the heating tubes 240 can also be arranged generally along the radial direction of the heating module, in which case the air inlet direction is perpendicular to the radial direction to achieve more uniform airflow and heating.

[0118] The regeneration module provided by the embodiment of the present invention is described in detail below in conjunction with the flow direction of the regeneration airflow.

[0119] Example 1

[0120] The heater air inlet 211 is located on the outer arc side of the regeneration module upper shell 210. The regeneration module upper shell 210 has a fan-shaped structure. The regeneration airflow enters the third airflow channel radially from the heater air inlet 211, enters the heater accommodating area through the air holes on the air equalizing plate 230, and exchanges heat with the heating tube 240. The high-temperature regeneration airflow after heating passes through the turntable 100 to dehydrate and dry the turntable 100 part in the regeneration area. The diameter of the air holes tends to decrease from the outer arc to the center of the circle along the radius of the sector. The heating tubes 240 are distributed in an S shape. The heating tubes 240 are spaced apart along the radius of the sector and the length of the heating tubes 240 is arranged perpendicular to the radius of the sector. Since the air holes on the air balancing plate 230 are arranged corresponding to the heating tubes 240, the diameter of the air holes is relatively larger near the heater air inlet 211, and the diameter of the air holes away from the heater air inlet 211 is relatively smaller, that is, the high-temperature regeneration air flow rate received by the turntable 100 in the regeneration area after heating decreases evenly or unevenly from the outer arc to the center of the circle along the radius of the sector, thereby achieving more uniform heating and drying of the turntable 100.

[0121] Example 2

[0122] The similarities between Example 2 and Example 1 are not repeated here. The difference between Example 2 and Example 1 is that:

[0123] The heater air inlet 211 is located on the sidewall of the regeneration module upper housing 210. The sidewall is arranged radially along a sector, and the regeneration airflow is arranged in the direction opposite to or in the same direction as the rotation direction of the turntable 100. The regeneration airflow enters the third airflow channel from the heater air inlet 211, enters the heater accommodation area through the air holes in the air distribution plate 230, and exchanges heat with the heating tube 240. The heated high-temperature regeneration airflow passes through the turntable 100 from top to bottom, dehydrating and drying the portion of the turntable 100 within the regeneration area. The heating tube 240 is arranged in an S-shaped pattern, with the length of the heating tube 240 being arranged parallel to the sidewall opposite the heater air inlet 211. The heating tube 240 is spaced radially along the sector. Because the air holes in the air distribution plate 230 are arranged corresponding to the heating tube 240, the air holes on the air distribution plate 230 away from the heater air inlet 211 are arranged relatively densely and with a larger diameter. The arrangement of the air holes controls the flow rate of the heated high-temperature regeneration airflow. When the turntable 100 absorbs moisture from the wet circulating airflow through the dehumidification zone and rotates to the regeneration zone, the turntable 100 is first dehydrated and dried with a high-temperature regeneration airflow at a larger flow rate. Then, when rotating through the regeneration zone, the flow rate of the high-temperature regeneration airflow is gradually reduced, thereby achieving more uniform heating and drying of the turntable 100.

[0124] As shown in Figure 12, the condensing module 4 may further include an upper condensing module housing 401 and a lower condensing module housing 402. The upper condensing module housing 401 and the lower condensing module housing 402 are coupled to form a condenser housing chamber, within which the condenser 43 is mounted. The arrows shown in Figure 9 indicate the direction of the regeneration airflow. The regeneration airflow passes from top to bottom through the turntable 100 to the fourth airflow channel, where it becomes moist and hot regeneration airflow, flows into the lower condensing module housing 402, and enters the condenser 43 for heat exchange and cooling.

[0125] In some embodiments, the drying module further includes a first connector 3013, whose ends are respectively connected to the condenser and the regeneration fan 22, so that the regeneration airflow enters the regeneration fan 22 via the condenser 43; and a second connector 3014, whose ends are respectively connected to the regeneration fan 22 and the heater air inlet, so that the regeneration airflow enters the third airflow channel via the regeneration fan 22. Because the condenser 43 and the regeneration fan 22 are very close, a rigid pipe joint as shown in FIG11 can be used, which not only supports the regeneration fan 22 but also makes the overall structure of the drying module compact and takes up little space. Of course, the first connector 3013 can also be a flexible member that can be easily connected to the two rigid structures of the condenser and the regeneration fan 22 air inlet.

[0126] In some embodiments, the first connector 3013 includes a first air inlet and a first air outlet. The first air inlet is adapted to and communicates with the condenser air outlet, and the first air outlet is adapted to and communicates with the air inlet of the regeneration fan 22. The first air inlet is a generally rectangular opening, and the first air outlet is a generally circular opening. The plane where the first air inlet is located is generally perpendicular to the plane where the first air outlet is located to adjust the flow direction of the regeneration airflow. The first air inlet end face of the first connector 3013 is provided with a rectangular connecting flange or a flexible boundary so that it is deformed and inserted into the condenser air outlet, and is connected and fixed to the condensing module upper shell 401 and the condensing module lower shell 402. The shell structure of the first connector 3013 is special-shaped. The air duct within the first connector 3013 gradually transitions from a rectangular cross-section at the first air inlet to a circular cross-section at the first air outlet, ensuring that the first connector 3013 can guide air smoothly.

[0127] In some embodiments, the second connecting member 3014 includes a second air inlet and a second air outlet. The second air inlet is adapted to and communicates with the air outlet of the regeneration blower 22, and the second air outlet is adapted to and communicates with the air inlet of the heater. The second air inlet is a generally rectangular opening, and the second air outlet is an arc-shaped opening. The plane on which the second air inlet and the plane on which the second air outlet are located are generally parallel, and the area of ​​the second air outlet is larger than that of the second air inlet. The air duct within the second connecting member 3014 gradually expands from the second air inlet to the second air outlet, thereby further converting the dynamic pressure energy of the airflow into static pressure energy, improving the dynamic pressure energy conversion capability, enhancing the operating performance of the blower, and minimizing the formation of turbulence.
