In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0058] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a drying module is provided, including a shell 1, in which a flow channel 31 and a dehumidification chamber 32 are provided, the flow channel 31 is connected with the air inlet 33 of the dehumidification chamber 32, so that the gas can enter the dehumidification chamber 32 through the flow channel 31, and a groove 121 is provided on the inner wall of the shell 1 at the air inlet 33 of the dehumidification chamber 32, so that the flow cross-sectional area of ​​the air inlet 33 of the dehumidification chamber 32 is larger than the flow cross-sectional area of ​​the flow channel 31.

[0059] By setting a dehumidification chamber 32 in the shell 1, the moisture absorption component can pass through the working position, thereby adsorbing humid gas and achieving a drying effect. By setting a flow channel 31 in the shell 1, a path can be provided for humid gas to enter the dehumidification chamber 32. By setting a groove 121 on the inner wall of the shell 1 at the air inlet 33 of the dehumidification chamber 32, the flow cross-sectional area of ​​the air inlet 33 of the dehumidification chamber 32 can be made larger than the flow cross-sectional area of ​​the flow channel 31. Compared with the existing drying module, the flow cross-sectional area at the air inlet 33 of the dehumidification chamber 32 can be increased without expanding the space occupied by the drying component, thereby increasing the air intake, reducing wind resistance, improving drying performance, shortening drying time, and improving drying efficiency.

[0060] The groove 121 is recessed toward a side away from the air inlet 33 of the dehumidification chamber 32, thereby expanding the flow cross-sectional area.

[0061] The dehumidification chamber 32 may be a chamber where the moisture absorption and dehumidification component 4 is located, and the flow passage 31 may be a passage between the dehumidification chamber 32 and the air inlet 33 of the shell 1 .

[0062] The wall of the dehumidification chamber 32 is connected to the channel wall of the flow channel 31 .

[0063] The flow cross-sectional area of ​​the air inlet 33 of the dehumidification chamber 32 refers to the cross-sectional area of ​​the air inlet 33 for gas to flow through. The flow cross-sectional area of ​​the flow channel 31 refers to the cross-sectional area of ​​the flow channel 31 for gas to flow through.

[0064] The number of the grooves 121 may be one or at least two, and the specific number is not limited in this embodiment.

[0065] At least a portion of the groove 121 is disposed in the dehumidification chamber 32, thereby ensuring that the entrance of the groove 121 and one side of the groove 121 close to the entrance have a larger flow cross-sectional area, thereby ensuring a larger air intake volume and further reducing wind resistance.

[0066] In this embodiment, at least half of the grooves 121 are disposed in the dehumidification chamber 32 .

[0067] The groove 121 may be roughly in the shape of an elongated strip along the flow direction, and at least half of the groove 121 away from the flow channel 31 along the length direction may be arranged in the dehumidification chamber 32 .

[0068] The groove 121 includes a first guide surface 1211 , a bottom surface 1212 , and a second guide surface 1213 which are sequentially arranged along the flow direction. The first guide surface 1211 and the second guide surface 1213 are respectively disposed at an obtuse angle to the bottom surface 1212 .

[0069] By providing the first guide surface 1211 and the second guide surface 1213 and making the first guide surface 1211 and the second guide surface 1213 respectively form an obtuse angle with the bottom surface 1212, a guiding effect can be provided when the gas flows through the groove 121, thereby further reducing the flow resistance and ensuring smooth flow of the gas.

[0070] The first guide surface 1211 , the bottom surface 1212 and the second guide surface 1213 are generally in a flared concave shape in a vertical section along the length direction.

[0071] When the gas flows through the groove 121, the gas first flows through the surface of the first guide surface 1211 on the upstream side of the flow direction, then flows to the surface of the bottom surface 1212, then flows through the bottom surface 1212, and then flows through the surface of the second guide surface 1213 along the flow direction. The above-mentioned gas refers to the entire gas flowing through the groove 121, and not all gas molecules flow along the surface of the first guide surface 1211, the surface of the bottom surface 1212, and the surface of the second guide surface 1213.

[0072] The bottom surface 1212 may be a plane and is arranged parallel to the plane where the gas flows as a whole in the flow channel 31 or the dehumidification chamber 32. For example, the gas flows on a horizontal plane as a whole, and the bottom surface 1212 may be arranged horizontally.

[0073] As a feasible implementation, the first guide surface 1211 and the second guide surface 1213 are planes, which reduces the difficulty of processing and facilitates the molding and manufacturing of the shell 1.

[0074] As another feasible implementation, the first guide surface 1211 and the second guide surface 1213 are arc surfaces, wherein the arc surfaces can be manufactured into a streamlined shape that is more conducive to airflow, which can further reduce wind resistance and ensure a good air intake effect.

[0075] Among them, the curved surface refers to a curved surface in the direction of gas flow, thereby reducing wind resistance.

[0076] Specifically, parameters such as the specific angle and length of the arc surface can be designed according to the actual air intake volume and air flow rate, that is, according to the actual parameters of the circulating fan. Guiding the gas flow through the arc surface is a relatively mature technical means, which will not be elaborated here.

[0077] At least a portion of the first guide surface 1211 is disposed in the flow channel 31, and can divert and guide the gas before the gas flows to the air inlet 33 of the flow channel 31 close to the dehumidification chamber 32, thereby further ensuring the smoothness of the gas flow, reducing wind resistance, and increasing the air intake.

[0078] One end of the first guide surface 1211 away from the bottom surface 1212 passes through the air inlet 33 and extends into the flow channel 31 .

[0079] The shell 1 includes a first shell 11 and a second shell 12 , the first shell 11 and the second shell 12 are snap-fitted, a flow channel 31 and a dehumidification chamber 32 are formed between the first shell 11 and the second shell 12 , and a groove 121 is arranged on the first shell 11 and / or the second shell 12 .

[0080] By configuring the housing 1 to include a first housing 11 and a second housing 12 that can be engaged with each other, installation of components within the housing 1 can be facilitated.

[0081] The first shell 11 may also be referred to as an upper shell 1 , and the second shell 12 may also be referred to as a lower shell 1 .

[0082] Among them, the second shell 12 can be a groove-type structure, and the first shell 11 can be set as a groove-type structure that is compatible with at least a portion of the second shell 12. The opening of the first shell 11 is engaged with the opening of the second shell 12, thereby forming a cavity in the middle, and the flow channel 31 and the dehumidification chamber 32 are part of the cavity.

[0083] Specifically, after the first shell 11 and the second shell 12 are buckled together, a plurality of cavities can be formed in the middle. The flow channel 31 and the dehumidification chamber 32 are two interconnected cavities, and can certainly be regarded as two parts of one cavity.

[0084] Specifically, the edge of the first shell 11 is buckled onto a portion of the edge of the second shell 12 to form an air inlet between the edge of the first shell 11 and the inner bottom wall of the second shell 12 .

[0085] As a feasible implementation, the groove 121 may be provided on the first shell 11 , that is, on the inner wall of the upper shell 1 , and may further be provided on the inner wall of the top surface of the upper shell 1 .

[0086] As another feasible implementation, the groove 121 can be set on the second shell 12, that is, on the inner wall of the lower shell 1, and can further be set on the inner wall of the bottom surface 1212 of the lower shell 1, or on the inner side wall of the lower shell 1.

[0087] As another feasible embodiment, the groove 121 can be set on the inner walls of the first shell 11 and the second shell 12 at the same time, and can further be set on the inner wall of the top surface of the upper shell 1 and the inner wall of the bottom surface 1212 of the lower shell 1 and the inner side wall of the lower shell 1.

[0088] In this embodiment, a first dehumidification chamber 32 is provided on the first shell 11, and a second dehumidification chamber 32 is provided on the second shell 12. The first dehumidification chamber 32 is provided corresponding to the second dehumidification chamber 32 to form the above-mentioned dehumidification chamber 32, and the groove 121 is provided at the entrance of the second dehumidification chamber 32 of the second shell 12. That is, when the shell 1 is provided horizontally, the groove 121 is provided on the inner bottom surface 1212 of the lower shell 1, and is recessed downward to form the groove 121.

[0089] The drying module includes a moisture absorption and dehumidification component 4, which is arranged in the shell 1. An integrally formed partition protrudes from the inner wall of the shell 1 toward the moisture absorption and dehumidification component 4 to separate at least a dehumidification chamber 32 in the shell 1.

[0090] By setting the moisture absorption and dehumidification component 4, the moisture in the gas flowing into the shell 1 can be absorbed, thereby achieving the effect of reducing humidity and drying clothes. By setting a partition on the inner wall of the shell 1 in the direction toward the moisture absorption and dehumidification component 4, the dehumidification chamber 32 can be separated, thereby providing a dehumidification space for the moisture absorption and dehumidification component 4. Compared with the prior art of setting a lower shell brush on the lower shell and making the lower shell brush contact and rub with the molecular sieve in the moisture absorption turntable to separate the dehumidification chamber 32, this embodiment can avoid the setting of the lower shell brush by making the partition and the inner wall of the shell 1 an integrated structure, so that the partition can directly separate the dehumidification chamber 32, and can avoid the problem of dust caused by the contact and friction between the lower shell brush and the molecular sieve in the moisture absorption turntable in the prior art, thereby avoiding the generated powder from returning to the washing chamber with the airflow to contaminate the clothes, and entering other components to cause component failure.

[0091] The partition and the housing 1 are an integrated structure.

[0092] Among them, the moisture absorption and dehumidification component 4 is a device with moisture absorption and dehumidification properties. In one embodiment, a moisture absorption and dehumidification component 4 is provided with a moisture absorbent for absorbing moisture. The moisture absorbent 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.), polymer moisture absorbent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina and other materials with moisture absorption properties. Among them, the polymer moisture absorbent is also called a polymer adsorbent, which has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents. In one embodiment, the moisture absorption and dehumidification component 4 can be made of porous materials such as zeolite, molecular sieve, metal organic framework (Metal Organic Framework, MOF) material, covalent organic framework material (Covalent Organic Frameworks, COFs), nanocarbon, silicon dioxide, etc. In one embodiment, the moisture absorption and dehumidification component 4 can also be formed by filling a granular solid or particle made of at least one porous material. In one embodiment, the moisture absorption and dehumidification component 4 can be a honeycomb or corrugated turntable carrying a desiccant, which can adsorb and desorb / desorb the absorbed water vapor to achieve repeated desorption and regeneration. In one embodiment, the moisture absorption and dehumidification component 4 includes an inorganic / organic fiber carrier (such as ceramics, glass fibers, MOFs, COFs, cordierite, etc.), and the fiber carrier is coated with a desiccant such as a molecular sieve, and the molecular sieve is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of airflow moisture. The molecular sieve may include single crystal molecular sieves or mixed crystal molecular sieves such as type A molecular sieves, X / Y type molecular sieves, ZSM molecular sieves, and Beta molecular sieves.

[0093] As a feasible implementation, the partition is arranged on the first shell 11 and / or the second shell 12 mentioned above, and the partition is in contact with the moisture absorption and dehumidification component 4, thereby achieving a good sealing effect and preventing humid gas from escaping from the dehumidification chamber 32 to other positions of the shell 1.

[0094] The partition may be provided only on the first shell 11, thereby separating the dehumidification chamber 32 on the first shell 11. The partition may be provided only on the second shell 12, thereby separating the dehumidification chamber 32 on the second shell 12. The partition may be provided on both the first shell 11 and the second shell 12, and the partition located on the first shell 11 and the partition located on the second shell 12 are provided correspondingly in the axial direction of the moisture absorption and dehumidification member 4, that is, the chamber separated by the partition on the first shell 11 and the chamber separated by the partition on the first shell 11 form the dehumidification chamber 32 relative to each other.

[0095] It should be noted that the contact between the partition and the moisture absorption and dehumidification component 4 means that the partition and the moisture absorption and dehumidification component 4 are just in contact but no pressure or only very small pressure is generated between them, so as to avoid the generation of powder when the moisture absorption and dehumidification component 4 moves.

[0096] As another feasible implementation, the partition is provided on the first shell 11 and / or the second shell 12, and a gap is provided between the partition and the moisture absorption and dehumidification component 4, so as to separate the dehumidification chamber 32. Moreover, since the flow rate of the humid gas is relatively fast, a relatively small gap can also make most of the humid gas be located in the dehumidification chamber 32. By providing a gap, the friction between the partition and the moisture absorption and dehumidification component 4 to generate powder can be avoided.

[0097] The partition may be provided only on the first shell 11, thereby separating the dehumidification chamber 32 on the first shell 11. The partition may be provided only on the second shell 12, thereby separating the dehumidification chamber 32 on the second shell 12. The partition may be provided on both the first shell 11 and the second shell 12, and the partition located on the first shell 11 and the partition located on the second shell 12 are provided correspondingly in the axial direction of the moisture absorption and dehumidification member 4, that is, the chamber separated by the partition on the first shell 11 and the chamber separated by the partition on the first shell 11 form the dehumidification chamber 32 relative to each other.

[0098] There is a gap of 0-5 mm between the partition and the moisture absorption and dehumidification component 4.

[0099] Specifically, in this embodiment, the gap between the partition and the moisture absorption and dehumidification component 4 may be 0.6-0.9 mm.

[0100] The partition part includes at least two first partition units 114 arranged on the first shell 11 and / or at least two second partition units 122 arranged on the second shell 12, so as to divide the internal space of the shell 1 into at least a dehumidification chamber 32 and a regeneration zone, thereby realizing the dehumidification function and the regeneration function.

[0101] Among them, two first partition units 114 can be set on the first shell 11, and two second partition units 122 can be set on the second shell 12, thereby dividing the internal space of the shell 1 into a dehumidification chamber 32 and a regeneration zone. Of course, three, four, or more first partition units 114 can be set on the first shell 11, and synchronously, three, four, or more second partition units 122 can be set on the second shell 12, thereby dividing the internal space of the shell 1 into more functional zones except the dehumidification chamber 32 and the regeneration zone. The number of the first partition unit 114, the second partition unit 122, and the functional zones can be specifically set according to actual needs, and this embodiment does not limit it.

[0102] It is understood that at least two first partition units 114 on the first shell 11 can also be divided into at least a dehumidification zone and a regeneration zone. At least two second partition units 122 on the second shell 12 can also be divided into at least a dehumidification zone and a regeneration zone.

[0103] The shapes of the first shell 11 and the second shell 12 in this embodiment can be designed according to the actual module structure of the washing machine, as long as they include at least two functional areas, namely the dehumidification chamber 32 and the regeneration zone. The shape of each functional area can also be designed according to actual needs, and can be square, triangular, circular, etc. As long as the dehumidification chamber 32 and the regeneration zone are isolated from each other and have a high degree of airtightness, the fan shape designed in this embodiment can make more effective and reasonable use of space. In addition, the moisture absorption and dehumidification component 4 is arranged between the first shell 11 and the second shell 12 to play the moisture absorption and dehumidification function. The present embodiment does not limit the shape of the moisture absorption and dehumidification component 4. It can be a polygon such as a triangle or a square, or it can be a wheel shape as shown in the figure. The wheel-shaped moisture absorption and dehumidification component 4 design can make the wheel circulate between the dehumidification chamber 32 and the regeneration zone. The part of the wheel that moves to the dehumidification chamber 32 absorbs moisture in the circulating airflow, and then the part of the wheel that absorbs moisture moves to the regeneration zone to desorb moisture, and the part of the wheel after desorption moves to the dehumidification chamber 32 again to absorb moisture, so as to remove moisture from the water vapor in a reciprocating manner, thereby achieving the effect of drying clothes. The setting of the first partition and the second partition makes the regenerated airflow and the wet circulating airflow not communicate with each other, and the regenerated airflow can only enter the condenser and will not dissipate, so that dynamic sealing is achieved during the rotation of the wheel.

[0104] At least two first partition units 114 extend radially along the dehumidification component 4 and are arranged circumferentially to separate a first dehumidification chamber 32 and a regeneration module installation portion on the first shell 11. At least two second partition units 122 extend radially along the dehumidification component 4 and are arranged circumferentially to separate a second dehumidification chamber 32 and a regeneration zone on the second shell 12. The first dehumidification chamber 32 and the second dehumidification chamber 32 are correspondingly arranged in the axial direction of the dehumidification component 4 to form a dehumidification chamber 32. The regeneration module installation portion and the regeneration zone are correspondingly arranged in the axial direction of the dehumidification component 4, which provides space for dehumidification operations and regeneration operations, and also provides a stable installation space for the regeneration module.

[0105] Specifically, in this embodiment, the two first partition units 114 extend radially along the moisture absorption and dehumidification component 4 and are arranged circumferentially to separate the first dehumidification chamber 32 and the regeneration module installation portion on the first shell 11, and the two second partition units 122 extend radially along the moisture absorption and dehumidification component 4 and are arranged circumferentially to separate the second dehumidification chamber 32 and the regeneration zone on the second shell 12.

[0106] The volume of the dehumidification chamber 32 is greater than the volume of the regeneration zone.

[0107] The first partition unit 114 and the second partition unit 122 may be protruding bosses or ribs.

[0108] Specifically, the first partition unit 114 can be a boss and a rib integrally formed with the first shell 11 and protruding toward the second shell 12, and the dehumidification chamber 32 and the regeneration zone are separated by the end faces of the protruding boss and the rib approaching or contacting the moisture absorption and dehumidification component 4.

[0109] Specifically, the second partition unit 122 may be a rib integrally formed with the second shell 12 and protruding toward the first shell 11 , and the dehumidification chamber 32 and the regeneration zone are separated by the end surface of the protruding rib approaching or contacting the moisture absorption and dehumidification component 4 .

[0110] Specifically, the first partition unit 114 is formed on the bottom of the groove 121 structure of the first shell 11 , and the second partition unit 122 is formed on the bottom of the groove 121 structure of the second shell 12 .

[0111] It should be noted that the first partition unit 114 and the second partition unit 122 extend in the radial direction of the moisture absorption and dehumidification component 4 as a whole, but do not necessarily extend in a straight line in the radial direction of the moisture absorption and dehumidification component 4.

[0112] The regeneration module installation portion provides an installation position for the regeneration module so that the regeneration module can desorb moisture on the moisture absorption and dehumidification component 4 in the regeneration zone. The first dehumidification chamber 32 and the second dehumidification chamber 32 are correspondingly arranged in the axial direction of the moisture absorption and dehumidification component 4 to form a complete dehumidification chamber 32, and the moisture absorption and dehumidification component 4 absorbs moisture in the gas in the dehumidification chamber 32.

[0113] The first partition unit 114 includes a partition boss protruding toward the second shell 12, and the second partition unit 122 includes a partition rib protruding toward the first shell 11. The protruding partition boss and the partition rib are arranged in a one-to-one correspondence, which can at least separate the dehumidification chamber 32 and the regeneration zone, and at the same time ensure a high degree of sealing, thereby reducing or blocking the flow of gas between the dehumidification chamber 32 and the regeneration zone.

[0114] The first partition unit 114 is a boss that is integrally formed with the first shell 11 and protrudes toward the second shell 12 .

[0115] Specifically, the boss and the convex ridges are formed on the bottom of the groove 121 structure of the first shell 11.

[0116] Specifically, the length direction of the separation boss may be approximately the radial direction of the moisture absorption and dehumidification component 4 , and the length direction of the separation surface may be approximately the axial direction of the moisture absorption and dehumidification component 4 , that is, extending toward the second shell 12 .

[0117] The partition bosses and the partition ribs are roughly arranged in one-to-one correspondence in the axial direction of the moisture absorption and dehumidification component 4.

[0118] An exhaust port 111 is provided on the first shell 11, and a wall surface of the dehumidification chamber 32 on the dehumidification chamber partition boss facing the dehumidification chamber is a partition surface 1141. A section of the partition surface 1141 close to the exhaust port 111 is inclined toward the exhaust port 111, thereby providing guidance for the exhaust of the dehumidification chamber 32, so that the gas in the dehumidification chamber 32 converges to the exhaust port 111 and then is discharged, thereby reducing the exhaust wind resistance.

[0119] The separation surface is the windward surface of the separation boss, that is, the outer surface in direct contact with the gas.

[0120] The flow cross-sectional area of ​​the exhaust port 111 is smaller than the flow cross-sectional area of ​​the dehumidification chamber 32 , and in the axial direction of the moisture absorption and dehumidification component 4 and in the direction toward the exhaust port 111 , a section of the dividing surface close to the exhaust port 111 gradually tilts toward the exhaust port 111 .

[0121] The section of the dividing surface close to the exhaust port 111 is substantially a curved surface or a flat surface, and the section of the dividing surface close to the exhaust port 111 gradually tilts toward the exhaust port 111 , that is, gradually twists toward the exhaust port 111 , thereby providing guidance for the airflow entering the exhaust port 111 .

[0122] Specifically, taking the first shell 11 being above the moisture absorption and dehumidification component 4 and the second shell 12 as an example, in the direction from bottom to top, a section of the dividing surface close to the exhaust port 111 gradually tilts and twists toward the exhaust port 111, so that the flow cross-sectional area on the air intake side of the exhaust port 111 decreases from bottom to top.

[0123] There are two first partition units 114. The partition surface of the first partition unit 114 close to the dehumidification chamber air inlet 33 is a plane, and the partition surface of the first partition unit 114 close to the dehumidification chamber exhaust port 111 is a curved surface extending along the radial direction of the moisture absorption and dehumidification component 4, and a section close to the exhaust port 111 is bent toward the exhaust port 111.

[0124] By setting the partition surface of the first partition unit 114 close to the dehumidification chamber exhaust port 111 as a curved surface along the radial direction of the moisture absorption and dehumidification component 4, the exhaust of the dehumidification chamber 32 can be further guided, which is beneficial to the exhaust of gas.

[0125] The length direction of the plane formed by the partition surface of the first partition unit 114 close to the dehumidification chamber air inlet 33 is roughly the radial direction of the moisture absorption and dehumidification component 4 , and the width direction is roughly the axial direction of the moisture absorption and dehumidification component 4 .

[0126] Among them, the partition surface of the first partition unit 114 near the dehumidification chamber exhaust port 111 is roughly S-shaped in the radial direction of the moisture absorption and dehumidification component 4. Because the flow cross-sectional area of ​​the exhaust port 111 is smaller than the flow cross-sectional area of ​​the dehumidification chamber 32, the partition surface near the exhaust port 111 gradually bends toward the exhaust port 111. The middle part of the partition surface bends toward the outside of the dehumidification chamber 32 so that the dehumidification chamber 32 has a larger volume, thus forming an S shape, which ensures that the dehumidification chamber 32 has a larger volume while further improving the smoothness of exhaust.

[0127] The partition ribs of the second partition unit 122 are arranged perpendicular to the moisture absorption and dehumidification component 4, which can ensure a good isolation effect while separating the dehumidification chamber 32 and the regeneration zone, reduce the processing difficulty of the second shell 12, and facilitate processing and manufacturing.

[0128] The length direction of the partition rib is roughly the radial direction of the moisture absorption and dehumidification component 4 , and the width direction is the direction perpendicular to the moisture absorption and dehumidification component 4 , that is, the axial direction of the moisture absorption and dehumidification component 4 .

[0129] The cross section of the partition rib is approximately rectangular, that is, the partition rib is a rectangular rib.

[0130] The partition ribs are formed on the bottom of the groove 121 structure of the second housing 12 .

[0131] There are two second partition units 122. The partition ribs of the second partition unit 122 near the dehumidification chamber air inlet 33 extend in a straight line, and the partition ribs of the second partition unit 122 near the dehumidification chamber exhaust port 111 extend in a fold line along the radial direction of the moisture absorption and dehumidification component 4, and the sharp angle of the fold line faces the inside of the dehumidification chamber 32.

[0132] By arranging the partition ribs of the second partition unit 122 near the dehumidification chamber exhaust port 111 to extend in a fold line along the radial direction of the moisture absorption and dehumidification component 4 with the sharp angle of the fold line facing the dehumidification chamber 32, the exhaust of the dehumidification chamber 32 can be further guided to facilitate gas discharge.

[0133] Among them, the partition ribs of the second partition unit 122 near the dehumidification chamber air inlet 33 extend roughly in a straight line along the radial direction of the moisture absorption and dehumidification component 4, and the partition ribs of the second partition unit 122 near the dehumidification chamber exhaust port 111 extend in a broken line along the radial direction of the moisture absorption and dehumidification component 4.

[0134] Among them, the partition ribs of the second partition unit 122 close to the exhaust port 111 of the dehumidification chamber include a first section 1221 and a second section 1222. The first section 1221 and the second section 1222 are arranged along the radial direction of the moisture absorption and dehumidification component 4, and both extend roughly in a straight line along the radial direction of the moisture absorption and dehumidification component 4. The windward surface of the first section 1221 and the windward surface of the second section 1222 are set at an angle greater than 180 degrees. The sharp angle formed by the first section 1221 and the second section 1222 faces the inside of the dehumidification chamber 32, which can provide good guiding effect on the airflow.

[0135] Among them, one end of the first section 1221 close to the second section 1222 extends roughly toward the exhaust port 111. Because the windward surface of the first section 1221 and the windward surface of the second section 1222 are set at an angle greater than 180 degrees, the end of the second section 1222 close to the exhaust port 111 extends more toward the exhaust port 111, thereby forming a function of guiding the gas flow.

[0136] The end face of the partition rib close to the moisture absorption and dehumidification component 4 is flat and parallel to the end face of the moisture absorption and dehumidification component 4, so that the distance between the partition rib and the moisture absorption and dehumidification component 4 is consistent, or the partition rib is better connected with the moisture absorption and dehumidification component 4 at all places, ensuring a good isolation effect and avoiding scratching the moisture absorption and dehumidification component 4 to produce powder.

[0137] In this embodiment, the end surface of the partition rib close to the moisture absorption and dehumidification member 4 and the end surface of the moisture absorption and dehumidification member 4 are both arranged horizontally.

[0138] A first flow guide 115 is arranged in the first shell 11. One end of the first flow guide 115 is arranged at the air inlet 33 of the dehumidification chamber, and the other end is connected to the first partition unit 114. The first flow guide 115 protrudes toward the moisture absorption and dehumidification component 4 to separate the first transition zone 71 in the first shell 11.

[0139] The first flow guide 115 is in contact with the moisture absorption and dehumidification component 4 or a gap is provided between the partition and the moisture absorption and dehumidification component 4 .

[0140] A second flow guide 123 is arranged in the second shell 12. One end of the second flow guide 123 is arranged at the air inlet 33 of the dehumidification chamber, and the other end is connected to the second partition unit 122. The second flow guide 123 protrudes toward the moisture absorption and dehumidification component 4 to separate a second transition zone 72 in the second shell 12.

[0141] The second flow guide 123 is in contact with the moisture absorption and dehumidification component 4 or a gap is provided between the partition and the moisture absorption and dehumidification component 4 .

[0142] The first flow guide 115 and the second flow guide 123 are correspondingly arranged in the axial direction of the moisture absorption and dehumidification component 4, so that the first transition zone 71 and the second transition zone 72 are opposite to each other in the axial direction of the moisture absorption and dehumidification component 4 to form a transition zone.

[0143] The transition zone is located in the dehumidification chamber.

[0144] An exhaust port 111 is provided on the first shell 11, one end of the first guide member 115 is provided at the air inlet 33 of the dehumidification chamber, and the other end extends in a straight line toward the exhaust port 111, and one end of the second guide member 123 is provided at the air inlet 33 of the dehumidification chamber, and the other end extends in a straight line toward the exhaust port 111. The gas entering through the air inlet 33 can be guided so that the gas can enter the dehumidification chamber more quickly and absorb moisture quickly.

[0145] The drying module includes a circulating fan, which is used to drive the gas to flow into the shell 1. The circulating fan includes a fan shell 5. The shell 1 includes the above-mentioned first shell 11 and second shell 12. The first shell 11 and the fan shell 5 are buckled on the second shell 12. The first shell 11 includes a first outer surface 112, and the fan shell 5 includes a second outer surface. A sealing member 61 is sandwiched between the first outer surface 112 and the second outer surface.

[0146] By providing a circulating fan, the gas to be dehumidified can be introduced into the housing 1 for dehumidification. By buckling the first housing 11 and the fan housing 5 on the second housing 12, a flow passage 31 and a dehumidification chamber 32 can be formed, which can provide a channel for gas flow. By providing the first epitaxial surface 112 and the second epitaxial surface, a setting position can be provided for the seal 61, so that the seal 61 is sandwiched between the first epitaxial surface 112 and the second epitaxial surface, thereby ensuring a good sealing effect.

[0147] The fan housing 5 and the second housing 12 are buckled together to form a flow passage 31 , and the first housing 11 and the second housing 12 are buckled together to form a dehumidification chamber 32 .

[0148] The sealing member 61 may be a sealing strip.

[0149] The first epitaxial surface 112 is arranged in parallel with and overlaps the second epitaxial surface, so that the sealing member 61 can be firmly clamped therein to prevent the sealing member 61 from coming out and causing air leakage.

[0150] The first epitaxial surface 112 and the second epitaxial surface are overlapped in the axial direction of the moisture absorption and dehumidification component 4 .

[0151] Specifically, the first epitaxial surface 112 and the second epitaxial surface may be arranged parallel to the moisture absorption and dehumidification component 4 .

[0152] Specifically, the seal 61 is arranged on the outer wall of the first extension surface 112, and the seal 61 is arranged on the inner wall of the second extension surface. After the first shell 11 and the second shell 12 are assembled, the seal 61 can be pressed by the second extension surface of the fan shell 5, making the assembly steps more reasonable and ensuring good assembly efficiency.

[0153] The outer wall of the first epitaxial surface 112 is the wall surface of the first epitaxial surface 112 away from the flow channel 31 .

[0154] The inner wall of the second epitaxial surface is the wall of the second epitaxial surface facing the flow channel 31 .

[0155] A sealing groove 62 is provided on the outer wall of the first epitaxial surface 112 and / or the inner wall of the second epitaxial surface, and a sealing member 61 is provided in the sealing groove 62, which can further improve the sealing effect and prevent the sealing member 61 from falling out, thereby ensuring good sealing. In the existing related technology, a bridge member is provided at the moisture absorption channel of the lower shell 1, which is used to connect and seal the upper shell 1 and the shell 1 of the circulating fan, but the provision of the bridge member is not conducive to the demolding of the lower shell 1, which increases the difficulty of manufacturing. Compared with the prior art, in this embodiment, a sealing groove 62 is provided on the outer wall of the first epitaxial surface 112 and / or the inner wall of the second epitaxial surface, which optimizes the mold structure and facilitates mold molding.

[0156] In some feasible embodiments, the sealing groove 62 can be arranged on the outer wall of the first epitaxial surface 112 or on the inner wall of the second epitaxial surface. In this embodiment, the sealing groove 62 is arranged on the outer wall of the first epitaxial surface 112, which can be more conducive to assembly work.

[0157] In some feasible embodiments, the first part of the sealing groove 62 is opened on the outer wall of the first epitaxial surface 112, and the second part of the sealing groove 62 can be opened on the inner wall of the second epitaxial surface. The first part and the second part are interlocked to form the sealing groove 62. The sealing member 61 is arranged in the sealing groove 62, which can also achieve a good sealing effect.

[0158] The drying module includes a moisture absorption and dehumidification component 4 . An abutment portion is provided on the inner wall of the shell 1 . The abutment portion protrudes toward the moisture absorption and dehumidification component 4 and abuts against the moisture absorption and dehumidification component 4 .

[0159] By providing an abutment portion on the inner wall of the shell 1, and making the abutment portion protrude toward the moisture absorption and dehumidification component 4 and abut against the moisture absorption and dehumidification component 4, the moisture absorption and dehumidification component 4 can be made to slide in contact with the abutment portion with a smaller contact area when the moisture absorption and dehumidification component 4 rotates, thereby avoiding the moisture absorption and dehumidification component 4 from contacting the inner wall of the shell 1 with a large area, thereby reducing the friction force when the moisture absorption and dehumidification component 4 rotates, making the rotation smoother and ensuring the normal progress of the dehumidification operation. At the same time, by providing the abutment portion, the moisture absorption and dehumidification component 4 can rotate more smoothly, so that when the moisture absorption and dehumidification component 4 rotates, the distance between the first partition unit 114 and the second partition unit 122 and the moisture absorption and dehumidification component 4 is more constant, thereby ensuring a good separation effect while further avoiding the first partition unit 114 and the second partition unit 122 from rubbing against the moisture absorption and dehumidification component 4 to produce powder.

[0160] The abutting portion may be connected to the inner wall of the housing 1 , or may be integrally formed with the housing 1 .

[0161] The abutting portion protrudes from the inner wall of the shell 1 toward the moisture absorption and dehumidification component 4 , that is, the abutting portion is closer to the moisture absorption and dehumidification component 4 than the inner wall of the shell 1 .

[0162] The abutment portion abuts against the axial end face of the moisture absorption and dehumidification component 4, so that the abutment portion can continue to abut against the end face of the moisture absorption and dehumidification component 4 when the moisture absorption and dehumidification component 4 rotates, thereby avoiding a large area of ​​contact between the moisture absorption and dehumidification component 4 and the inner wall of the shell 1, and also ensuring that the rotation of the moisture absorption and dehumidification component 4 is more stable.

[0163] The moisture absorption and dehumidification component 4 is roughly a turntable-shaped structure. The moisture absorption and dehumidification component 4 rotates around its own central axis as the rotation center. The end faces of the moisture absorption and dehumidification component 4 are the two end faces of the moisture absorption and dehumidification component 4 in the axial direction.

[0164] The abutting portion is provided on the inner wall of the housing 1 opposite to the end surface of the moisture absorption and dehumidification member 4 .

[0165] Specifically, the moisture absorption and dehumidification member 4 can be arranged horizontally, that is, the upper end surface and the lower end surface of the moisture absorption and dehumidification member 4 are arranged horizontally. The inner wall of the shell 1 above the moisture absorption and dehumidification member 4 is arranged opposite to and parallel to the upper end surface of the moisture absorption and dehumidification member 4. The inner wall of the shell 1 below the moisture absorption and dehumidification member 4 is arranged opposite to and parallel to the lower end surface of the moisture absorption and dehumidification member 4. The abutment portion can be arranged on the inner wall of the shell 1 above or below the moisture absorption and dehumidification member 4, and protrude toward the moisture absorption and dehumidification member 4.

[0166] The moisture absorption and dehumidification component includes an adsorption component and a driving component, and the abutting portion abuts against the driving component; the moisture absorption and dehumidification component 4 includes an adsorption component 41 and a driving component 42, and the abutting portion abuts against the driving component 42. The friction between the abutting portion and the adsorption component 41 to avoid the generation of powder, and the driving component 42 is usually made of metal or plastic and other materials, and the surface is relatively smooth, which further reduces the friction between the abutting portion and the moisture absorption and dehumidification component 4.

[0167] The driving component 42 is sleeved on the outer peripheral side of the adsorption component 41, and the abutting portion and the driving component 42 are arranged opposite to each other in the axial direction of the moisture absorption and dehumidification component 4, so that the abutting portion continuously abuts against the driving component 42 when the moisture absorption and dehumidification component 4 rotates.

[0168] Specifically, the driving component 42 may be a ring gear, which is annular, and the adsorption component 41 is disc-shaped, and the driving component 42 is sleeved on the outer peripheral wall of the adsorption component 41 along the circumference of the adsorption component 41. The abutment portion extends toward the end surface of the driving component 42, and then abuts on the end surface of the driving component 42.

[0169] More specifically, in this embodiment, the moisture absorption and dehumidification component 4 is horizontally arranged, the driving component 42 is sleeved on the outer peripheral wall of the upper half of the adsorption component 41, and the abutting portion is arranged on the inner wall of the shell 1 above the driving component 42 and protrudes downward from the inner wall.

[0170] Among them, the adsorption component 41 can be a zeolite molecular sieve, A / X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc., and the driving component 42 can be coaxially arranged on a toothed disk with the adsorption component 41. The toothed disk is transmission-connected to the power component, so that the power component drives the adsorption component 41 to rotate through the driving component 42, and the abutment portion abuts against the disk surface of the toothed disk.

[0171] Among them, the thickness of the driving component 42 is smaller than the thickness of the adsorption component 41, and the driving component 42 is sleeved on a section of the outer wall of the adsorption component 41 close to the first shell 1, that is, the minimum distance between the driving component 42 and the first shell 1 is smaller than the minimum distance between the driving component 42 and the second shell 12.

[0172] The second shell 12 includes a first step groove and a second step groove, the second step groove is provided on the bottom of the first step groove to form at least part of the dehumidification chamber 32, and the abutment portion is provided on the bottom of the first step groove. By providing the first step groove, the second shell 12 can be adapted to buckle the driving component 42 therein, and by providing the second step groove, at least part of the dehumidification chamber 32 can be formed, providing space for the dehumidification operation. By providing the abutment portion on the bottom of the first step groove, the abutment portion can continuously abut against the end face of the driving component 42 when the moisture absorption and dehumidification component 4 rotates, thereby avoiding large-area contact between the moisture absorption and dehumidification component 4 and the inner wall of the shell 1, and can also provide a supporting effect to ensure that the rotation of the moisture absorption and dehumidification component 4 is more stable.

[0173] The edge of the second shell 12 is connected to the first shell 11 , the inner side of the edge of the second shell 12 is recessed to form a first stepped groove, and the bottom of the first stepped groove is recessed to form a second stepped groove at the bottom of the first stepped groove.

[0174] The first step groove and the second step groove are recessed toward the same side.

[0175] Specifically, in this embodiment, the first shell 11 is located above the second shell 12, and the first stepped groove and the second stepped groove are both recessed upward.

[0176] The abutment portion includes a plurality of abutment units 113, which are arranged along the circumference of the moisture absorption and dehumidification component 4, so that the moisture absorption and dehumidification component 4 can be in contact with the abutment units 113 in the circumferential direction, thereby avoiding large-area friction between the moisture absorption and dehumidification component 4 and the inner wall of the shell 1, and at the same time, it can also provide good support for the moisture absorption and dehumidification component 4, ensuring that the moisture absorption and dehumidification component 4 can rotate stably.

[0177] The plurality of abutment units 113 are arranged in a circular shape on the inner wall of the housing 1 , and the circular shape is coaxially arranged with the moisture absorption and dehumidification component 4 , that is, the abutment portion is coaxially arranged with the moisture absorption and dehumidification component 4 .

[0178] The abutting units 113 have the same height, which ensures that the abutting units 113 can fully contact the moisture absorption and dehumidification components 4, thereby ensuring a good supporting effect.

[0179] The height of the abutting unit 113 refers to the height of the abutting unit 113 in the axial direction of the moisture absorption and dehumidification member 4 .

[0180] The abutting units 113 may be arranged in parallel.

[0181] Abutment unit 113 Abutment unit 113

[0182] All the abutting units 113 are arranged in parallel and have the same height, so that each abutting unit 113 abuts against the moisture absorption and dehumidification component 4 .

[0183] One end of the abutting unit 113 is connected to the bottom of the first stepped groove, and the other end extends linearly toward the moisture absorption and dehumidification component 4 .

[0184] The bottom of the first stepped groove is arranged parallel to the moisture absorption and dehumidification component 4 , and the height direction of the abutting unit 113 is perpendicular to the bottom of the first stepped groove and the moisture absorption and dehumidification component 4 , respectively.

[0185] More specifically, the circular shape of the plurality of abutting units 113 matches the annular shape of the driving component 42 , so that the abutting units 113 can abut against the end surface of the annular shape of the driving component 42 .

[0186] As a feasible implementation, the abutting unit 113 is a protrusion, which can make the abutting unit 113 easier to process and have higher structural strength.

[0187] Among them, the multiple protrusions are arranged in parallel and have the same height, so that each protrusion can be in contact with the moisture absorption and dehumidification component 4, thereby ensuring that the supporting effect of the protrusions at various locations is the same.

[0188] Among them, one end of the protrusion close to the moisture absorption and dehumidification component 4 is a curved surface, which can further reduce the friction between the moisture absorption and dehumidification component 4 and avoid scratching the moisture absorption and dehumidification component 4.

[0189] The protrusion and the first shell 11 can be integrally formed.
