[0132] The air outlet plate 1331 and the air inlet plate 1332 can be spliced together with the first side plate 1321 and the second side plate 1322, and the air outlet plate 1331 and the air inlet plate 1332 can be provided with matching plug-in structures on the first side plate 1321 and the second side plate 1322, for example, one of the two adjacent plates is provided with a plug hole or a slot, and the other is provided with a matching plug structure; or both plates are provided with plug holes, slots and plug structures. For example, two mica sheets can be used as the air outlet plate 1331 and the air inlet plate 1332.

[0133] Of course, the air outlet plate 1331 and the air inlet plate 1332 can also be connected together with the first side plate 1321 and the second side plate 1322 by bonding, riveting, threaded connection and the like, and the present disclosure does not limit this.

[0134] The air outlet plate 1331 and the air inlet plate 1332 can also have a connection relationship between the top plate 1311, the bottom plate 1312, the first side plate 1321 and the second side plate 1322, so as to improve the stability after connection; the connection mode can adopt one of the connection modes discussed above, and the present disclosure does not limit this.

[0135] As shown in FIGS. 7 and 8, the assembly shell 131 further comprises a third side plate 1323 and a fourth side plate 1324, the third side plate 1323 is located on the side of the first side plate 1321 away from the second side plate 1322 and connected with the first side plate 1321, and the fourth side plate 1324 is located on the side of the second side plate 1322 away from the first side plate 1321 and connected with the second side plate 1322. By providing the third side plate 1323 and the fourth side plate 1324, the third side plate 1323 and the fourth side plate 1324 are made of insulating and heat insulating materials, which facilitates the fixation of the heating assembly 130 in the shell of the heating module 100.

[0136] The third side plate 1323 and the fourth side plate 1324 can be spliced together with the top plate 1311, the bottom plate 1312, the first side plate 1321, the second side plate 1322, the air outlet plate 1331 and the air inlet plate 1332 to form an integral assembly shell 131. For example, one of the two adjacent plates is provided with a plug hole or a slot, and the other is provided with a matching plug structure; or both plates are provided with plug holes, slots and plug structures. For example, two mica sheets can be used as the third side plate 1323 and the fourth side plate 1324.

[0137] As shown in FIGS. 16 and 17, the structure of the third side plate 1323 and the fourth side plate 1324 can be the same, that is, by processing and producing one grid plate, the third side plate 1323 and the fourth side plate 1324 can be used at the same time, which reduces the production cost, improves the production effect, and also facilitates the assembly and maintenance of the assembly shell 131.

[0138] As shown in FIG. 7, after the first side plate 1321 is spliced with the third side plate 1323, a mounting hole is formed on the overlapping part of the first side plate 1321 and the third side plate 1323; after the second side plate 1322 is spliced with the fourth side plate 1324, a mounting hole is formed on the overlapping part of the second side plate 1322 and the fourth side plate 1324; the heating assembly 130 is fixed in the air duct of the heating module 100 through the mounting parts on both sides of the assembly shell 131.

[0139] As shown in FIG. 6, FIG. 7 and FIG. 9, the assembly shell 131 further comprises a support 1340, the support 1340 comprises opposite first and second ends, the first end is connected with the first side plate 1321, and the second end is connected with the second side plate 1322; wherein the electric heating element comprises an electric heating wire, and the electric heating wire is wound on the support 1340. The support 1340 made of insulating and heat-insulating material forms a support for the electric heating wire, so that the electric heating wire can be fixed in the accommodation space by winding, so that the heating wire 1350 can provide sufficient heating area and improve the heating effect on the gas sent by the regenerative blower 150.

[0140] As shown in FIG. 9, a plurality of supports 1340 can be arranged in the accommodation space in the third direction Y from the air inlet to the air outlet, and an electric heating wire is wound on each support 1340. By arranging a plurality of supports 1340 in the direction of gas flow, and winding an electric heating wire on each support 1340, the gas can be heated multiple times, and the reliability of the electric heating element is improved.

[0141] Specifically, among at least two adjacent supports 1340, the diameter of the electric heating wire wound on the support 1340 close to the air outlet is greater than the diameter of the electric heating wire wound on the support 1340 close to the air inlet.

[0142] The temperature of the gas close to the air inlet is low, the electric heating wire cools down quickly and is least likely to overheat, so by winding a thinner electric heating wire on the support 1340 close to the air inlet, the resistance can be reduced, the temperature of the heating wire 1350 can be increased, and the heating power can be improved; the temperature of the gas close to the air outlet is relatively high after being heated, the electric heating wire cools down slowly and is easy to overheat, so by winding a thicker electric heating wire on the support 1340 close to the air outlet, the resistance is increased, the heating temperature is reduced, the heat generation efficiency per unit time is reduced, the safety hazard caused by the heating wire 1350 being red is prevented, and the reliability of the heating element is improved.

[0143] As shown in FIG. 9, in the third direction Y from the air inlet to the air outlet, three rows of support members 1340 can be provided, and in the two adjacent rows of support members 1340, the diameter of the electric heating wire wound on the support member 1340 close to the air outlet is greater than the diameter of the electric heating wire wound on the support member 1340 close to the air inlet. Of course, only two rows of support members 1340 can also be provided, or three, four or more rows of support members 1340 can be provided, which is not limited in the present disclosure.

[0144] Specifically, in the third direction Y from the air inlet to the air outlet, the spacing between adjacent support members 1340 increases. The gas temperature close to the air inlet is low, the electric heating wire cools down quickly and is least likely to be red, and the gas close to the air outlet is relatively high in temperature after being heated, and the electric heating wire cools down slowly and is prone to be red; by increasing the spacing between adjacent support members 1340 in the third direction Y, the density of electric heating close to the air outlet is relatively reduced, thereby preventing the heating wire 1350 close to the air outlet from being red to cause safety hazards and improving the reliability of the heating element. Of course, the spacing between adjacent support members 1340 can also be the same, which is not limited in the present disclosure.

[0145] As shown in FIGS. 9 and 10, in the first direction Z, the electric heating wire wound on the support member 1340 includes a bending section located between the support member 1340 and the assembly housing 131; in the third direction Y, the spacing between the part close to the middle region of the support member 1340 in the bending section and the support member 1340 in the first direction Z is greater than the spacing between the part close to the edge region of the support member 1340 and the support member 1340 in the first direction Z.

[0146] By making the spacing between the part close to the middle region of the support member 1340 in the bending section of the heating wire 1350 and the support member 1340 in the first direction Z greater than the spacing between the part close to the edge region of the support member 1340 and the support member 1340 in the first direction Z, i.e., the bending section bends towards the peripheral side of the assembly housing 131 in the accommodation space, the coverage area of the heating wire 1350 in the accommodation space is increased, and therefore the heating uniformity of the gas can be improved.

[0147] As shown in FIGS. 9 and 10, when the heating wire 1350 is wound on the support member 1340, the shape of one turn is a hexagon, so that the heating wire 1350 covers a larger area.

[0148] As shown in FIG. 11, the at least part of the edge of the support 1340 is formed with a tooth structure 1341, and the at least part of the electric heating wire is wound on the tooth structure 1341. When the heating wire 1350 is wound on the support 1340, the edge of the tooth structure 1341 forms a plurality of limiting grooves, and the heating wire 1350 is wound in the limiting grooves, avoiding the displacement or winding gap of the heating wire 1350 after being wound on the support 1340, and improving the winding efficiency and winding effect of the heating wire 1350.

[0149] Wherein, the two sides of the support 1340 are formed with tooth structures 1341, which position the winding of the heating wire 1350, so that the heating wire 1350 is distributed at equal intervals on the support 1340, improving the heating effect of the heating wire 1350, and also improving the reliability of the heating wire 1350, avoiding the safety hazard of red-hot heating wire due to too small local interval.

[0150] As shown in FIG. 9 and FIG. 10, in the first direction Z, a plurality of supports 1340 are arranged in the accommodation space, and the electric heating wire is wound on the plurality of supports 1340. By arranging a plurality of supports 1340 in the first direction Z, the heating wire 1350 can cover a larger area after being wound, and the stability of the heating wire 1350 after being wound can be improved, avoiding the change of the interval between the heating wires 1350.

[0151] Wherein, in the first direction Z, two supports 1340 can be arranged in the accommodation space, and the heating wire 1350 is wound on the two supports 1340, increasing the area that can be covered. Of course, three, four or more supports 1340 can also be arranged in the first direction Z, and the present disclosure does not limit this.

[0152] Specifically, the electric heating element further comprises a temperature controller, the temperature controller is connected with the electric heating wire, and the temperature controller is used for monitoring the heat value generated by the heating wire 1350, and can control the heat generation of the heating wire 1350 according to the heat value, so that the heating wire 1350 heats the gas input by the regenerative blower 150 to a preset temperature and outputs.

[0153] Wherein, the temperature controller can be arranged in the accommodation space of the assembly shell 131, so as to more accurately obtain the heat value generated by the heating wire 1350. Of course, the temperature controller can also be arranged outside the assembly shell 131, and a connecting hole is arranged on the assembly shell 131 to connect the temperature controller with the heating wire 1350.

[0154] The electric heating element includes a plurality of temperature controllers. As shown in FIG. 9, a first temperature controller 1361 is arranged between the support members 1340, so that the first temperature controller 1361 is closer to the center of the heating area formed by the heating wire 1350, and more accurate heat value monitoring information is obtained. As shown in FIG. 10, a second temperature controller 1362 is arranged on the other side in the second direction X, and the second temperature controller 1362 is arranged between the support members 1340, so that the second temperature controller 1362 is closer to the center of the heating area formed by the heating wire 1350, and more accurate heat value monitoring information is obtained.

[0155] Of course, one temperature controller can also be arranged, or three, four or more temperature controllers can also be arranged, and part of the temperature controllers can be arranged in the assembly housing 131, and part of the temperature controllers can be arranged outside the assembly housing 131, which is not limited in the present disclosure.

[0156] In an embodiment, the temperature controller can also be a fuse, a fuse link or a similar fuse, which is used to disconnect the heating when the temperature reaches a preset temperature value, so as to protect the heater.

[0157] As shown in FIGS. 9 and 10, the assembly housing 131 further includes a first connecting plate 1371 and a second connecting plate 1372, which are located at both ends of the support members 1340 in the second direction X; the first connecting plate 1371 and the second connecting plate 1372 connect the plurality of support members 1340 in the third direction Y, so as to improve the stability between the plurality of rows of support members 1340.

[0158] In the third direction Y, the support members 1340 close to the bottom plate 1312 are connected together by the first connecting plate 1371 and the second connecting plate 1372. Of course, the support members 1340 close to the top plate 1311 can also be connected together by the first connecting plate 1371 and the second connecting plate 1372, which is not limited in the present disclosure.

[0159] In an embodiment, as shown in FIGS. 20-25, the module housing of the heating module includes opposite first and second ends 101 and 102, the first end 101 is formed with an air inlet 103, the second end 102 is formed with an air outlet 104, and the air duct connecting the air inlet 103 and the air outlet 104 is formed between the first and second ends 101 and 102. In the first direction Z perpendicular to the third direction Y pointing from the first end 101 to the second end 102, the height of the heating assembly 130 region in the air duct is greater than the height of the region without the heating assembly 130; the third direction Y can be the length direction of the module housing, and the first direction Z can be the height direction of the module housing.

[0160] The heating module 100 provided by the present disclosure, at the position where the heating assembly 130 is arranged, by making the height of the area in the air duct where the heating assembly 130 is arranged greater than the height of the area where the heating assembly 130 is not arranged, when the regenerative fan 150 sends cold air to the position where the heating assembly 130 is located, because the height of the air duct at this position is relatively greater than the height of other areas, the air duct with greater height is conducive to the air flow being collected to the heating assembly 130 for a period of time and then entering the dehumidification module through the air outlet 104, thereby improving the heating effect of the air flow by the heating module 100, and the heating temperature of the heated air flow is suitable for desorbing the moisture on the moisture desorption and discharge element.

[0161] Specifically, the module housing includes an upper housing 110 and a lower housing 120, and the upper housing 110 and the lower housing 120 are buckled to form an air duct with an air inlet 103 and an air outlet 104. A protruding portion 121 protruding towards the side away from the upper housing 110 is formed on a large surface of the lower housing 120, and the heating assembly 130 is located between the protruding portion 121 of the lower housing 120 and the upper housing 110.

[0162] The accommodation space of the heating assembly 130 is formed by the protruding portion 121 of the lower housing 120, so that the heating assembly 130 is installed in the air duct. Because the air flow sinks, the air volume at the upper part of the air duct is less than that at the lower part, and the space at the lower part of the air duct where the heating assembly 130 is arranged is increased, so that more heat generated by the heating assembly 130 is in the lower part with greater air volume, thereby improving the heating effect on the air flow.

[0163] As shown in FIGS. 21 and 22, a protruding structure 111 protruding towards the side away from the lower housing 120 can also be arranged on the upper housing 110, so as to cooperate with the protruding portion 121 on the lower housing 120 to form an enlarged air duct accommodating the heating assembly 130.

[0164] In one embodiment, as shown in FIGS. 26-28, the heating module 100 further includes a heat insulation element 160 arranged in the air duct and located between the heating assembly 130 and the air outlet 104, and the heat insulation element 160 is arranged adjacent to the inner wall of the module housing. The module housing is usually a plastic part, and the high-temperature hot air after being heated by the heating assembly 130 has the risk of melting the plastic part. By arranging the heat insulation element 160 in the air duct, the hot air passes through the heat insulation element 160 to transfer heat to the module housing, which can greatly reduce the temperature rise of the module housing caused by the high-temperature hot air; for example, if the high-temperature hot air directly blows to the module housing, the temperature of the module housing will rise to 200-300° high temperature. By arranging the heat insulation element 160, the temperature of the module housing can be maintained at about 150°, thereby avoiding damage to the module housing caused by high-temperature gas, and reducing the requirement for the heat resistance of the module housing, thereby reducing the manufacturing cost of the module housing.

[0165] The heat insulation piece 160 can be formed of aluminum, sheet metal, or other heat insulation materials, or can be formed of mica sheet, asbestos, or high-temperature-resistant plastic (polyimide PI, polyether ether ketone PEEK, polyamide-imide PAI, polybenzimidazole PBI, polyetherimide PEI, polyphenylene sulfide PPS, nylon 46, polysulfone PSU, polyether sulfone PES, polytetrafluoroethylene PTFE, polyvinylidene fluoride PVDF, etc.), and the present disclosure does not limit this. Any change in insulating and heat-insulating materials is within the protection scope of the present disclosure.

[0166] The heat insulation piece 160 can be attached to the inner wall of the air duct of the module housing, or can be arranged at a small preset distance, so that the high-temperature airflow heated by the heating assembly 130 can flow out through the heat insulation piece 160.

[0167] As shown in FIGS. 26-28, the heat insulation piece 160 is formed with a heat insulation air duct, the inlet of the heat insulation air duct is arranged adjacent to the heating assembly 130, and the outlet of the heat insulation air duct is in communication with the air outlet 104. In the first direction Z, at least part of the heat insulation air duct is tapered in the third direction Y, that is, the cross-sectional height of the heat insulation air duct formed by the heat insulation piece 160 at one end close to the heating assembly 130 is greater than that at the other end away from the heating assembly 130, and the cross-sectional height gradually decreases, so as to prevent the formation of turbulence on the side away from the heating assembly 130 and the aggregation of hot air, which can cause local overheating.

[0168] As shown in FIGS. 26-28, in the first direction Z, the heat insulation piece 160 includes oppositely arranged heat insulation top plate 161 and heat insulation bottom plate 162, and at least part of the heat insulation bottom plate 162 is inclined toward the side close to the heat insulation top plate 161 in the third direction Y, so that at least part of the heat insulation air duct is tapered in the third direction Y. Alternatively, at least part of the heat insulation top plate 161 is inclined toward the side close to the heat insulation bottom plate 162 in the third direction Y, so that at least part of the heat insulation air duct is tapered in the third direction Y. Alternatively, at least part of the heat insulation top plate 161 and the heat insulation bottom plate 162 are inclined toward each other in the third direction Y. The heat insulation top plate 161 and the heat insulation bottom plate 162 facilitate the arrangement of the tapered heat insulation air duct.

[0169] As shown in FIGS. 27 and 28, the heat insulation bottom plate 162 is provided with an inclined portion 1621 on the side close to the heating assembly 130, so that the heat insulation air duct is tapered in the third direction Y. The heat insulation top plate 161 is entirely inclined, so that the airflow can better flow out through the air outlet 104.

[0170] As shown in FIG. 28, the heat insulation bottom plate 162 is in abutment or has a small gap between the side close to the heating assembly 130 and the shell of the heating assembly 130. Due to the arrangement of the inclined portion 1621, when the high-temperature airflow flows through the heating assembly 130 to the space between the heat insulation bottom plate 162 and the heat insulation top plate 161, the high-temperature airflow needs to rise at the position of the inclined portion 1621, and the flow rate of the high-temperature airflow is relatively fast. The abutment of the side of the heat insulation bottom plate 162 close to the heating assembly 130 and the shell of the heating assembly 130 can avoid high-temperature damage to the module shell caused by the airflow with a relatively fast flow rate passing through the gap between the heat insulation bottom plate 162 and the shell of the heating assembly 130.

[0171] In one embodiment, as shown in FIGS. 20-31, the heating module 100 further comprises a wind uniformizing member 140, which is arranged at or close to the air outlet 104 of the air duct. The heated gas flows out through the guide of the wind uniformizing member 140. The wind uniformizing member 140 can make the heated gas flow out more uniformly, so as to improve the dehumidification effect on the moisture absorbing and dehumidifying member.

[0172] The wind uniformizing member 140 comprises a first portion and a second portion. The sum of the areas of the plurality of air outlets per unit area of the first portion is greater than the sum of the areas of the plurality of air outlets per unit area of the second portion.

[0173] As shown in FIGS. 4 and 29, the wind uniformizing member 140 comprises a first wind uniformizing plate 141 arranged in the air duct. The first wind uniformizing plate 141 is provided with a plurality of first air outlets 1410. The large surface of the first wind uniformizing plate 141 intersects the third direction Y. In one embodiment, the first wind uniformizing plate 141 is arranged perpendicular or substantially perpendicular to the third direction Y. It should be understood by those skilled in the art that the wind uniformizing plate is a plate-shaped member, which generally has an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface. The large surface referred to in the present application is the upper surface or the lower surface with the largest area.

[0174] The first wind uniformizing plate 141 is arranged in the air duct to uniformize the airflow in the air duct. Due to the rotation direction S of the impeller of the regenerative blower 150 and the sinking of the airflow, the flow rate and / or unit heat of the heated airflow at different positions of the air duct interface are different, which leads to uneven heating of the moisture absorbing and dehumidifying member and affects the drying effect of the drying module.

[0175] Specifically, in the second direction X intersecting the third direction Y and the first direction Z, the first uniform air plate 141 includes opposite first and second sides; the regenerative fan 150 is a centrifugal fan, the rotating shaft of the centrifugal fan extends along the first direction Z; the impeller of the centrifugal fan rotates in a direction from the first side to the second side at a position close to the first uniform air plate 141, the first part is arranged in the first region close to the first side, and the second part is arranged in the second region close to the second side, that is, the second side of the first uniform air plate 141 is located on the side of the first side toward the rotation direction S, and the area sum of the plurality of first air outlets 1410 per unit area in the first region 1411 close to the first side on the first uniform air plate 141 is greater than the area sum of the plurality of first air outlets 1410 per unit area in the second region 1412 close to the second side. Wherein, the second direction X can be perpendicular to the third direction Y and the first direction Z, and the second direction X can be the width direction of the module shell.

[0176] Wherein, the regenerative fan 150 usually adopts a centrifugal fan, the airflow blown by the centrifugal fan is output along the direction of the impeller thereof, which can cause the air quantity on the two sides of the air duct in the rotation direction S to be different, and the air quantity on the second side of the air duct is greater than that on the first side; when the gas provided by the regenerative fan 150 enters the moisture absorption and removal piece through the heating assembly 130, it can cause the temperature at the second side of the first uniform air plate 141 to be too high, which can easily cause uneven heating of the moisture absorption and removal piece. The present disclosure makes the area sum of the plurality of first air outlets 1410 per unit area in the first region 1411 close to the first side on the first uniform air plate 141 greater than the area sum of the plurality of first air outlets 1410 per unit area in the second region 1412 close to the second side, so that the air resistance of the first side of the first uniform air plate 141 is relatively smaller than that of the second side. Therefore, the air quantity of the first side and the second side can be homogenized, the heating of the moisture absorption and removal piece can be uniform, and the dehumidification effect can be improved.

[0177] Specifically, in the first direction Z, the first uniform air plate 141 includes opposite third and fourth sides, the third side is close to the top of the module shell, that is, close to the upper shell 110; the fourth side is close to the bottom of the module shell, that is, close to the lower shell 120; the first part is arranged in the third region close to the third side, and the second part is arranged in the fourth region close to the fourth side, that is, the area sum of the plurality of first air outlets 1410 per unit area in the third region close to the third side on the first uniform air plate 141 is greater than the area sum of the plurality of first air outlets 1410 per unit area in the fourth region close to the fourth side.

[0178] Due to the influence of factors such as gas sinking, the air volume of the airflow after heating in the air duct close to the lower shell 120 is greater than that close to the upper shell 110, thereby causing uneven heating of the moisture absorbing and discharging piece, affecting the drying effect of the drying module. The present disclosure makes the area sum of the plurality of first air outlets 1410 per unit area in the third region close to the third side of the first air uniformizing plate 141 greater than that in the fourth region close to the fourth side, so that the air resistance of the third side of the first air uniformizing plate 141 is relatively smaller than that of the fourth side, thereby achieving uniformization of the air volume of the third side and the fourth side, making the heating of the moisture absorbing and discharging piece uniform, and improving the dehumidification effect.

[0179] Specifically, as shown in FIG. 30, in the second direction X, the first air uniformizing plate 141 further includes a middle region 1413 between the first side and the second side; the air uniformizing piece 140 further includes a third part, and the area sum of the plurality of air outlets per unit area of the first part and the area sum of the plurality of air outlets per unit area of the second part are both greater than the area sum of the plurality of air outlets per unit area of the third part, that is, the area sum of the plurality of first air outlets 1410 per unit area in the first region 1411 close to the first side and the area sum of the plurality of first air outlets 1410 per unit area in the second region 1412 close to the second side are both greater than the area sum of the plurality of first air outlets 1410 per unit area in the middle region 1413.

[0180] When the regenerative fan 150 adopts a wide-port centrifugal fan (the width of the regenerative fan 150 air outlet 104 and the regenerative fan 150 / air duct width are basically kept consistent), etc., the air volume in the middle of the air duct is the largest, and the air volume on one side of the side is greater than that on the other side. The present disclosure makes the area sum of the plurality of first air outlets 1410 per unit area in the first region 1411 close to the first side and the area sum of the plurality of first air outlets 1410 per unit area in the second region 1412 close to the second side are both greater than the area sum of the plurality of first air outlets 1410 per unit area in the middle region 1413, so that the air resistance of the first side and the second side of the first air uniformizing plate 141 is relatively smaller than that of the middle region 1413, thereby achieving uniformization of the air volume of the first side, the second side and the center region 1425, making the heating of the moisture absorbing and discharging piece uniform, and improving the dehumidification effect.

[0181] The diameter of the first air outlet hole 1410 on the first portion is greater than the diameter of the first air outlet hole 1410 on the second portion, and the diameter of the first air outlet hole 1410 on the second portion is greater than the diameter of the first air outlet hole 1410 on the third portion. The first portion, the second portion, and the third portion are arranged with a plurality of first air outlet holes 1410 in an array. By making the diameter of the first air outlet hole 1410 on the first portion greater than the diameter of the first air outlet hole 1410 on the second portion, and making the diameter of the first air outlet hole 1410 on the second portion greater than the diameter of the first air outlet hole 1410 on the third portion, and under the condition that the distribution density of the first air outlet holes 1410 is the same, the air resistance on the first side is less than the air resistance on the second side, and the air resistance on the second side is less than the air resistance on the third side, thereby improving the air volume on the first side and reducing the air volume near the second side, so that the air volume on the first side is equivalent to the air volume on the second side and the third side, and the uniform air effect is achieved.

[0182] Of course, the diameter of the first air outlet hole 1410 on the first portion can also be equal to the diameter of the first air outlet hole 1410 on the second portion and the third portion. By increasing the distribution density of the first air outlet hole 1410 on the first portion, the air resistance on the first side is less than the air resistance on the second side. By increasing the distribution density of the first air outlet hole 1410 on the second portion, the air resistance on the second side is less than the air resistance on the middle region 1413. Alternatively, the diameter and distribution density of the first air outlet hole 1410 on the first portion, the second portion, and the third portion can also be adjusted at the same time, so that the sum of the areas of the plurality of first air outlet holes 1410 per unit area in the first region 1411 near the first side on the first uniform air plate 141 is greater than the sum of the areas of the plurality of first air outlet holes 1410 per unit area in the second region 1412 near the second side; the sum of the areas of the plurality of first air outlet holes 1410 per unit area in the second region 1412 near the second side is greater than the sum of the areas of the plurality of first air outlet holes 1410 per unit area in the middle region 1413. The present disclosure does not limit this.

[0183] In addition, more regions can be provided on the first uniform air plate 141 to provide first air outlet holes 1410 with different air volumes in different regions to achieve the uniform air effect. The present disclosure does not limit this.

[0184] Specifically, as shown in FIG. 29, the air uniformizing piece 140 includes a second uniform air plate 142 located at the air outlet 104, and the large surface of the second uniform air plate 142 intersects the first direction Z. In an embodiment, the first uniform air plate 141 is perpendicular or substantially perpendicular to the first direction Z. The second uniform air plate 142 is provided with a plurality of second air outlet holes 1420.

[0185] The third portion is further included on the air uniformizing member 140, the sum of the areas of the plurality of second air outlets 1420 per unit area in the first portion is greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the second portion, and the sum of the areas of the plurality of second air outlets 1420 per unit area in the first portion and the second portion is greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the third portion. The second air uniformizing plate 142 includes a central region and an edge region surrounding the central region, the first portion is arranged in the central region, and the second portion and the third portion are arranged in the edge region.

[0186] As shown in FIG. 31, in the third direction Y, the second air uniformizing plate 142 includes opposite first and second edge regions 1421 and 1422 and a central region 1425 between the first and second edge regions 1421 and 1422.

[0187] The third portion is further included on the air uniformizing member 140, the sum of the areas of the plurality of second air outlets 1420 per unit area in the first portion is greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the second portion, and the sum of the areas of the plurality of second air outlets 1420 per unit area in the first portion and the second portion is greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the third portion. The second air uniformizing plate 142 includes a central region and an edge region surrounding the central region, the first portion is arranged in the central region, and the second portion and the third portion are arranged in the edge region.

[0188] When the high-temperature gas provided by the heating module enters the moisture absorbing and removing member, the position of the air outlet 104 of the air duct corresponding to the moisture absorbing and removing member requires a higher temperature in the middle of the moisture absorbing and removing member to better achieve the dehumidification effect. By making the sum of the areas of the plurality of second air outlets 1420 per unit area in the central region 1425 greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the first and second edge regions 1421 and 1422, the central region 1425 has a larger flow of high-temperature gas, which can better heat the middle of the moisture absorbing and removing member and improve the dehumidification effect of the moisture absorbing and removing member.

[0189] Specifically, as shown in FIG. 31, the first edge region 1421 is located on the side of the second edge region 1422 close to the heating assembly 130, the fourth portion is arranged in the first edge region 1421, and the second portion is arranged in the second edge region 1422, that is, the sum of the areas of the plurality of second air outlets 1420 per unit area in the second edge region 1422 is greater than the sum of the areas of the plurality of second air outlets 1420 per unit area in the first edge region 1421.

[0190] The first edge area 1421 is close to the outlet air, and the air resistance of the heating airflow in the first edge area 1421 is smaller than that in the second edge area 1422, resulting in that the air volume at the first edge area 1421 is relatively large. The present disclosure increases the air resistance of the first edge area 1421 and reduces the air resistance of the second edge area 1422 by making the area sum of the plurality of second air outlets 1420 per unit area in the second edge area 1422 greater than the area sum of the plurality of second air outlets 1420 per unit area in the first edge area 1421, thereby being capable of homogenizing the air volume of the first edge area 1421 and the second edge area 1422, making the heating of the moisture absorbing and removing piece uniform, and improving the dehumidification effect.

[0191] Specifically, as shown in FIG. 31, in the second direction X intersecting the third direction Y and the first direction Z, the second air uniformizing plate 142 includes opposite third edge area 1423 and fourth edge area 1424. The air outlet 104 of the heating module 100 is arranged opposite to the moisture absorbing and removing piece of the drying module, the rotation shaft of the moisture absorbing and removing piece extends along the first direction Z, and the same position of the moisture absorbing and removing piece rotates in the direction of the third edge area 1423 towards the fourth edge area 1424 at the position of the second air uniformizing plate 142.

[0192] Among them, the third part is arranged in the third edge area 1423, and the second part is arranged in the fourth edge area 1424. The area sum of the plurality of second air outlets 1420 per unit area in the third part is greater than the area sum of the plurality of second air outlets 1420 per unit area in the second part, that is, the area sum of the plurality of second air outlets 1420 per unit area in the third edge area 1423 is greater than the area sum of the plurality of second air outlets 1420 per unit area in the central area 1425.

[0193] When the moisture absorbing and removing piece rotates, the parts in the rotation direction are sequentially opposite to the position of the air outlet 104 of the heating module 100 to be heated and dehumidified by the high-temperature airflow; the part corresponding to the air outlet 104 first has a relatively low temperature, which gradually increases during rotation, until the temperature increases and dehumidification after rotation away from the position corresponding to the air outlet 104. The heating module 100 provided by the present disclosure makes the area sum of the plurality of second air outlets 1420 per unit area in the third edge area 1423 greater than the area sum of the plurality of second air outlets 1420 per unit area in the central area 1425, and greater than the area sum of the plurality of second air outlets 1420 per unit area in the fourth edge area 1424, so that the upstream air volume is relatively large when the moisture absorbing and removing piece dehumidifies, and the downstream air volume is relatively small, which can rapidly heat the moisture absorbing and removing piece just entering the dehumidification position, and improve the dehumidification effect; at the same time, avoid the downstream temperature being too high to cause the shell piece to be hot.

[0194] The diameter of the second air outlet hole 1420 on the first part is greater than the diameter of the second air outlet hole 1420 on the second part, the diameter of the second air outlet hole 1420 on the third part is greater than the diameter of the second air outlet hole 1420 on the first part, and the diameter of the second air outlet hole 1420 on the second part is less than the diameter of the second air outlet hole 1420 on the fourth part. The first part, the second part, the third part and the fourth part are arrayed with a plurality of second air outlet holes 1420. In the case of a comparable distribution density of the second air outlet holes 1420, the area sum of the second air outlet holes 1420 on the first part is greater than the area sum of the second air outlet holes 1420 on the second part, the area sum of the second air outlet holes 1420 on the third part is greater than the area sum of the second air outlet holes 1420 on the first part, and the area sum of the second air outlet holes 1420 on the second part is less than the area sum of the second air outlet holes 1420 on the fourth part.

[0195] Of course, the diameters of the second air outlet holes 1420 on the first part, the second part, the third part and the fourth part can also be the same. By adjusting the distribution density of the second air outlet holes 1420 on the first part, the second part, the third part and the fourth part, the area sum of the second air outlet holes 1420 on the first part is greater than the area sum of the second air outlet holes 1420 on the second part, the area sum of the second air outlet holes 1420 on the third part is greater than the area sum of the second air outlet holes 1420 on the first part, and the area sum of the second air outlet holes 1420 on the second part is less than the area sum of the second air outlet holes 1420 on the fourth part. Alternatively, the diameter and the distribution density of the second air outlet holes 1420 on the first part, the second part, the third part and the fourth part can also be adjusted at the same time, so that the area sum of the second air outlet holes 1420 on the first part is greater than the area sum of the second air outlet holes 1420 on the second part, the area sum of the second air outlet holes 1420 on the third part is greater than the area sum of the second air outlet holes 1420 on the first part, and the area sum of the second air outlet holes 1420 on the second part is less than the area sum of the second air outlet holes 1420 on the fourth part. The present disclosure does not limit this.

[0196] Specifically, as shown in FIGS. 26-29, the air uniformizing piece 140 further comprises an air guide side plate 143. The air uniformizing piece 140 is arranged on the air outlet 104 of the module shell. Since the air outlet 104 faces the moisture absorbing and removing piece, by arranging the air guide side plate 143 on the air uniformizing piece 140, the high-temperature airflow can enter the moisture absorbing and removing piece through the second air guide plate, thereby improving the dehumidification effect.

[0197] The air guide side plate 143 connects the first air uniformizing plate 141 and the second air uniformizing plate 142, thereby improving the structural strength of the air uniformizing piece 140.

[0198] The uniform air piece 140 can be integrally formed by sheet metal bending, and the first air outlet hole 1410 and the second air outlet hole 1420 are formed on the metal plate by punching, which facilitates the edge forming and drilling of the metal plate.

[0199] The uniform air piece 140 and the heat insulation piece 160 can be made of the same material, for example, both the uniform air piece 140 and the heat insulation piece 160 are made of aluminum alloy. Of course, the uniform air piece 140 and the heat insulation piece 160 can also be made of different materials, for example, the uniform air piece 140 is made of a metal plate, and the heat insulation piece 160 is made of a mica sheet or other heat insulation material.

[0200] The uniform air piece 140 can be a spliced structure, which is formed by splicing a plurality of plate pieces, thereby reducing the difficulty of the manufacturing process and reducing the manufacturing cost. For example, the first uniform air plate 141 and the second uniform air plate 142 can be formed by punching a whole plate respectively, and the air guide side plate 143 is formed by splicing a plurality of side plates.

[0201] The heat insulation piece 160 can be a spliced structure, which is formed by splicing a plurality of plate pieces, thereby reducing the difficulty of the manufacturing process and reducing the manufacturing cost. For example, the heat insulation top plate 161 and the heat insulation bottom plate 162 of the heat insulation piece 160 are formed by splicing a plurality of mica sheets, and the heat insulation top plate 161 can also be formed by splicing a plurality of mica sheets, and the heat insulation bottom plate 162 can also be formed by splicing a plurality of mica sheets.

[0202] Specifically, the heating assembly 130 can include an assembly shell 131 and an electric heating element, the electric heating element includes an electric heating wire and a temperature controller, the electric heating wire is arranged in the assembly shell 131, the assembly shell 131 is formed with a heating air duct, and the airflow input by the regenerative air blower 150 is heated through the heating air duct; the temperature controller is connected with the electric heating wire, and the temperature controller is used for monitoring the heat value generated by the electric heating wire, and can control the heat value of the electric heating wire according to the heat value, so that the electric heating wire heats the gas input by the regenerative air blower 150 to a preset temperature and outputs.

[0203] The temperature controller can be arranged in the accommodation space of the assembly shell 131, so as to more accurately obtain the heat value generated by the electric heating wire. Of course, the temperature controller can also be arranged outside the assembly shell 131, and a connecting hole is arranged on the assembly shell 131 to connect the temperature controller with the electric heating wire.

[0204] As shown in FIGS. 1 and 2, the drying module 10 comprises a dehumidification module 200 and the heating module 100 provided in the above embodiments. As shown in FIG. 34, the dehumidification module 200 comprises a dehumidification shell and a moisture absorption and removal piece 230. The dehumidification shell is provided with a receiving space having an air inlet and an air outlet. At least part of the moisture absorption and removal piece 230 is arranged in the receiving space. The moisture absorption and removal piece 230 is configured to be capable of absorbing moisture in the gas entering the receiving space. At least part of the moisture absorption and removal piece 230 is arranged opposite to the air outlet on the shell of the heating module 100. The heating module 100 is configured to dehydrate the part of the moisture absorption and removal piece 230 located at the air outlet. The moisture absorption and removal piece 230 can be a rotating disc. The edge of the rotating disc can be provided with gear teeth. The gear teeth of the rotating disc are engaged with the gear connected to the output shaft of the motor to drive the rotating disc to rotate.

[0205] Specifically, the air outlet of the dehumidification module 200 is communicated with the air inlet of the clothes treatment drum 20. The air inlet of the dehumidification module 200 is communicated with the air outlet of the clothes treatment drum 20. The moisture in the gas in the clothes treatment drum 20 is continuously absorbed by the dehumidification module 200. The heating module 100 can heat the air flow and / or the moisture absorption and removal piece 230. The heated air flow passes through the moisture absorption and removal piece 230 in the dehumidification module 200 to dehydrate the moisture absorption and removal piece 230, so that the moisture absorption and removal piece 230 has the ability to absorb moisture again. During the rotation of the moisture absorption and removal piece 230, the air flow continuously passes through the dehumidification area of the dehumidification module 200 and the dehydration area of the heating module 100 to realize the cycle process of absorbing and desorbing moisture, thereby achieving the purpose of drying the moisture of the clothes in the clothes treatment drum 20. As shown in FIG. 34, the moisture absorption and removal piece 230 can be a rotating disc with gear teeth on the edge. The rotating disc rotates to pass through the dehumidification area of the dehumidification module 200 and the dehydration area of the heating module 100.

[0206] As shown in FIG. 34, the dehumidification shell comprises a first dehumidification shell 210 and a second dehumidification shell 220. The first dehumidification shell 210 and the second dehumidification shell 220 enclose a receiving space in which at least part of the moisture absorption and removal piece 230 is arranged. The first dehumidification shell 210 and the second dehumidification shell 220 are respectively provided with air vents as the air inlet and the air outlet. The first dehumidification shell 210 is provided with a heating air hole 211.

[0207] The first dehumidification shell 210 is provided with a fan-shaped heating air hole 211. The heating module 100 is installed on the fan-shaped heating air hole 211. The heating module 100 is located above the moisture absorption and removal piece 230. The fan-shaped heating air hole 211 is used to make the heating module 100 and the moisture absorption and removal piece 230 have a larger heating area.

[0208] Specifically, the first dehumidifying shell 210 and the moisture absorption and removal component 230 have a first gas flow channel, and the second dehumidifying shell 220 and the moisture absorption and removal component 230 also have a second gas flow channel. The first gas flow channel and the second gas flow channel form a dehumidifying area of the moisture absorption and removal component 230. The humid gas in the clothes treatment drum 20 can enter the first gas flow channel, absorb moisture by the moisture absorption and removal component 230, and then be discharged through the second gas flow channel. Alternatively, the humid gas in the clothes treatment drum 20 can enter the second gas flow channel, absorb moisture by the moisture absorption and removal component 230, and then be discharged through the first gas flow channel.

[0209] The outlet of the heating module 100 is in communication with the heating air hole 211 on the first dehumidifying shell 210, that is, the third gas flow channel is formed between the heating module 100 and the moisture absorption and removal component 230. The fourth gas flow channel is formed between the second dehumidifying shell 220 and the moisture absorption and removal component 230. The fourth gas flow channel of the second dehumidifying shell 220 is separated from the second gas flow channel by the blocking component, so as to separate the dehumidifying area and the dewatering area. The high-temperature dry gas after heating enters the third gas flow channel to perform moisture desorption on the moisture absorption and removal component 230. The humid gas after passing through the moisture absorption and removal component 230 enters the fourth gas flow channel. During the rotation of the moisture absorption and removal component 230, each part in the circumferential direction continuously passes through the dehumidifying area and the dewatering area, thereby continuously performing the cycle process of moisture absorption and desorption, and finally achieving the drying purpose of the clothes in the clothes treatment drum 20.

[0210] The dehumidifying area and the dewatering area are relatively isolated, so that the first gas flow channel and the dehumidifying gas flow in the second gas flow channel and the third gas flow channel and the dewatering gas flow in the fourth gas flow channel are not communicated with each other, thereby ensuring the dewatering effect of the humid gas.

[0211] In an embodiment, the heating module 100 further comprises a heat blocking component. The heat blocking component is arranged at the outlet 104 of the module shell, located on the side of the outlet 104 close to the heating assembly 130, and is arranged opposite to the edge area of the moisture absorption and removal component 230 between the module shell and the dehumidifying shell.

[0212] As shown in FIGS. 32 and 33, the lower shell and the first dehumidifying shell 210 have a gap 170. When the moisture absorption and removal component 230 is stationary, and the heating assembly 130 is still on in the abnormal state, heat is easily transferred to the first dehumidifying shell 210 on the outer circle of the moisture absorption and removal component 230 through the gap 170, which causes the risk of thermal melting of the first dehumidifying shell 210.

[0213] The present disclosure can prevent heat from being transferred to the first dehumidifying shell 210 at the gap by arranging a heat blocking component in the gap 170, thereby protecting the first dehumidifying shell 210 on the outer side of the moisture absorption and removal component 230 from thermal melting in the abnormal state that the moisture absorption and removal component 230 is stationary and the heating assembly is still on.

[0214] Specifically, the moisture absorption and removal member 230 can be made of a material with good moisture absorption performance to improve the moisture absorption capacity of the moisture absorption and removal member 230 for the humid gas, thereby improving the drying effect on the clothes in the clothes treatment cylinder 20. The material of the moisture absorption and removal member 230 includes lithium chloride, silica gel, zeolite, molecular sieve, etc., and the present disclosure does not make any limitation thereon.

[0215] The moisture absorption and removal member 230 can be provided with a moisture absorption agent for absorbing moisture. The moisture absorption agent can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to zeolite molecular sieve, A / X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), high molecular moisture absorption agent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc. The high molecular moisture absorption agent is also known as a polymer adsorbent, which has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents.

[0216] The moisture absorption and removal member 230 can be made of porous materials such as zeolite, molecular sieve, metal organic framework (MOF) material, covalent organic framework material (COF), nano-carbon, and silicon dioxide. In an embodiment, the moisture absorption and removal member 230 can also be formed by filling granular solids or particles made of at least one of the above-mentioned porous materials.

[0217] The moisture absorption and removal member 230 can be a honeycomb or corrugated moisture absorption and removal member 230 loaded with a moisture absorption agent, which can adsorb and desorb / strip the absorbed water vapor to realize repeated desorption and regeneration.

[0218] The moisture absorption and removal member 230 can include inorganic / organic fiber carriers (such as ceramic, glass fiber, MOF, COF, cordierite, etc.), and the fiber carriers are coated with a moisture absorption agent such as molecular sieve, which is uniformly distributed between the fiber carriers and the surface of the fiber carriers to realize the adsorption of the moisture in the air flow. The molecular sieve can include single crystal molecular sieve or mixed crystal molecular sieve such as A type molecular sieve, X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.

[0219] The present disclosure does not make any limitation on the specific material of the moisture absorption and removal member 230, and any moisture absorption and removal member 230 that can realize the moisture absorption and removal effect belongs to the protection scope of the present disclosure.

[0220] As shown in FIG. 1 and FIG. 2, the drying module 10 is further provided with a circulation module 300, which comprises a blower. The air inlet of the blower is in communication with the air outlet of the clothes treatment cylinder 20, and the air outlet of the blower is in communication with the air inlet of the dehumidification module 200, for sending the dehumidification gas in the clothes treatment cylinder 20 into the dehumidification module 200. After the dehumidification gas is treated by the dehumidification module 200, dry gas is formed, so that the wet circulating gas becomes dry circulating gas. The dry gas enters the clothes treatment cylinder 20 through the air inlet of the clothes treatment cylinder 20 to contact with the clothes, so as to achieve the purpose of circulating dehumidification of the clothes in the clothes treatment cylinder 20.

[0221] As shown in FIG. 1 and FIG. 2, the drying module 10 is further provided with a condensation module 400, which can condense and dehydrate the wet hot gas after the moisture of the wet hot gas is desorbed by the moisture absorption and dehumidification piece 230. The water vapor of the wet hot gas is cooled to form condensate water, which is discharged from the condenser, and the dry and cold dehumidification gas becomes dry and cold dehumidification gas, which enters the regenerative blower 150 of the heating module 100 and forms a closed loop circulation. Of course, the dry and cold dehumidification gas formed after the condenser treatment can also be directly discharged into the atmosphere, which is not limited in the present disclosure. The condensation module 400 can comprise a tubular condenser, which cools the wet hot gas to make the water vapor of the wet hot gas cooled to form condensate water, which is discharged from the condenser. The specific composition of the condensation module is not limited in the present disclosure.

[0222] The gas sent by the heating module 100 through the regenerative blower 150 can be dry and cold gas after the moisture of the wet hot gas is desorbed by the moisture absorption and dehumidification piece 230, that is, the gas is recycled. The humidity of the sent gas is relatively low, which can improve the drying efficiency and reduce the energy consumption. Alternatively, the regenerative blower 150 of the heating module 100 can directly suck gas from the outside.

[0223] Other embodiments of the present disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses or adaptations of the present disclosure that follow, in general, the principles of the present disclosure and include specific designs, features, structures, configurations, methods, procedures, components and equivalents thereof.
