[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples.

[0039] The dehumidification module 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1-Figure 3 As shown, the dehumidification module 100 according to an embodiment of the present invention includes: a mounting frame 1, a dehumidification component 2, a driving motor 4 and a desorption fan 5. A dehumidification air duct 11 is formed in the mounting frame 1. The dehumidification component 2 includes a rotating part and a desiccant arranged on the rotating part. The rotating part is rotatably arranged in the dehumidification air duct 11. The desiccant can be better carried and driven to rotate by the rotating part. The dehumidification air duct 11 includes an adsorption air duct 111 and a desorption air duct 112 arranged along the circumference of the dehumidification component 2. A heating component 3 is provided in the desorption air duct 12.

[0041] That is to say, the desiccant can be driven to move into the adsorption air duct 111 by the rotating part, and the water vapor in the gas in the adsorption air duct 111 can be adsorbed by the desiccant, so that the humidity of the gas in the adsorption air duct 111 can be reduced, that is, the dehumidification of the gas can be achieved. For example, the air inlet and outlet of the adsorption air duct 111 can both be connected to the indoor space, so that the air can be dehumidified during the continuous circulation between the adsorption air duct 111 and the indoor space; the desiccant can be driven to move into the desorption air duct 112 by the rotating part, wherein the heating element 3 can increase the temperature in the desorption air duct 112, so that the desiccant in the desorption air duct 112 can be heated, so that the moisture adsorbed by the desiccant can be desorbed, that is, the desiccant in the desorption air duct 112 can be dried by the heating element 3 to restore the moisture absorption capacity of the desiccant.

[0042] Therefore, during the operation of the dehumidification module 100, the rotating part can be rotated so that at least part of the dehumidification component 2 is located in the adsorption air duct 111, and the desiccant located in the adsorption air duct 111 adsorbs the water vapor in the adsorption air duct 111 to achieve dehumidification, and the rotating part can be rotated to move the part of the dehumidification component 2 located in the adsorption air duct 111 to the desorption air duct 112 to desorb the moisture in the desiccant, and the desorbed desiccant can re-enter the adsorption air duct 111 to absorb moisture as the rotating part rotates. In other words, at least part of the area on the dehumidification component 2 can be switched between the adsorption channel 111 and the desorption air duct 112 by the rotation of the rotating part, so that the dehumidification component 2 can be cycled in adsorption and desorption to improve the continuous dehumidification capacity of the dehumidification module 100.

[0043] Furthermore, the driving motor 4 is arranged on the mounting frame 1 and is in transmission connection with the rotating part, and the desorption fan 5 is used to drive the gas flow in the desorption air duct 112. That is to say, the driving motor 4 can provide driving force for the rotating part, and the rotating part rotates in the dehumidification air duct 11 under the drive of the driving motor 4, so as to realize the switching of at least a part of the area on the dehumidification element 2 between the adsorption air duct 111 and the desorption air duct 112, and the desorption fan 5 can provide driving force for the gas in the desorption air duct 112, so as to drive the gas flow in the desorption air duct 112, that is, to form an airflow passing through the dehumidification element 2 in the desorption air duct 112, and the heating element 3 can better heat the dehumidification element 2 located in the desorption air duct 11 2, so that the desiccant located in the desorption air duct 112 can desorb the adsorbed moisture into the airflow, that is, through the cooperation of the heating element 3 and the desorption fan 5, the desiccant located in the desorption air duct 112 can be dried to restore the water absorption performance of the desiccant, and the desorbed moisture such as water vapor can be discharged from the desorption channel 112 through the airflow in the desorption air duct 112, which can better avoid the desorbed moisture from remaining in the desorption air duct 112, which is beneficial to improving the desorption effect of the desiccant in the desorption area.

[0044] Furthermore, the desorption fan 5 and the heating element 3 are arranged along the first direction e1, and the first direction e1 is perpendicular to the axial direction of the dehumidifying element 2. Thus, the desorption fan 5 and the heating element 3 can make full use of the installation space of the dehumidification module 100 in the first direction e1, thereby effectively saving the installation space occupied by the desorption fan 5 and the heating element 3 in the axial direction of the dehumidifying element 2, and further reducing the size of the dehumidification module 100 in the axial direction of the dehumidification element 2, which is conducive to reducing the installation space occupied by the dehumidification module 100.

[0045] According to the dehumidification module 100 of the embodiment of the present invention, the dehumidification component 2 is rotatably arranged in the dehumidification air duct 11, and the dehumidification air duct 11 includes an adsorption air duct 111 and a desorption air duct 112 arranged along the circumferential direction. A heating component 3 is provided in the desorption air duct 112. The rotation of the rotating part drives the desiccant to move between the adsorption air duct 111 and the desorption air duct 112, so that the desiccant can be cycled in adsorption and desorption, and the continuous dehumidification capacity is strong. At the same time, the desorption fan 5 and the heating component 3 are arranged along the first direction e1 perpendicular to the axial direction of the dehumidification component 2, so that the axial size of the dehumidification module 100 in the dehumidification component 2 can be better controlled, which is beneficial to reduce the installation space occupied by the dehumidification module 100.

[0046] According to some embodiments of the present invention, the rotating part has at least two parts respectively located in the adsorption air duct 111 and the desorption air duct 112, and the desiccant is at least provided on the part of the rotating part located in the adsorption air duct 111 and the desorption air duct 112. That is to say, the rotating part may have only two parts respectively located in the adsorption air duct 111 and the desorption air duct 112, and the rotating part may also have a part located outside the adsorption air duct 111 and the desorption air duct 112; the desiccant may be provided only on the part of the rotating part located in the adsorption air duct 111 and the desorption air duct 112, and the desiccant may also be provided on the part of the rotating part located outside the adsorption air duct 111 and the desorption air duct 111, or the desiccant may be provided on the entire rotating part, and no specific limitation is made here.

[0047] Among them, the desiccant on the part of the rotating part located in the adsorption air duct 111 can absorb the water vapor in the adsorption channel 111. Therefore, the part of the rotating part located in the adsorption air duct 111 can be formed as the area where the dehumidifier 2 adsorbs water vapor in the air, which is hereinafter referred to as the adsorption area for the convenience of description. When the gas in the adsorption air duct 111 passes through the adsorption area, the desiccant in the adsorption area can better reduce the water vapor content in the gas passing through the adsorption area, that is, the dehumidification treatment of the gas is achieved. For example, the gas in the indoor space can flow directly into the adsorption air duct 111, and after being dehumidified by the adsorption area, it is discharged back to the indoor space, thereby achieving the dehumidification treatment of the indoor space; while the desiccant in the adsorption area absorbs the water vapor in the adsorption air duct 111, the desiccant on the part of the rotating part located in the desorption air duct 112 can be desorbed by the cooperation of the heating element 3 and the desorption air duct 5, that is, the part of the rotating part located in the desorption air duct 112 can be formed as the area where the dehumidifier 2 desorbs moisture, which is hereinafter referred to as the desorption area for the convenience of description. In other words, the part of the dehumidifier 2 located in the adsorption air duct 111 is performing adsorption while the part of the dehumidifier 2 located in the desorption air duct 112 is performing desorption, which can better ensure that adsorption and desorption are performed simultaneously on the dehumidifier 2. At the same time, the desiccant in the adsorption area can enter the desorption air duct 112 for desorption after adsorption, and the desiccant in the desorption area can enter the adsorption air duct 111 for adsorption after desorption, which can better reduce the waiting time for adsorption or desorption and better improve the dehumidification efficiency of the dehumidification module 100.

[0048] Specifically, the desorption zone and the adsorption zone are arranged along the circumference of the dehumidifier 2. After the desiccant in the adsorption zone absorbs water, the rotating part can be rotated so that the part of the rotating part located in the adsorption air duct 111 can be moved to the desorption air duct 112 to desorb the moisture of the desiccant to restore the adsorption capacity of the desiccant. The desiccant after the drying treatment can re-enter the adsorption air duct 111 to absorb moisture as the rotating part rotates.

[0049] According to some embodiments of the present invention, the desiccant is one of molecular sieve, silica gel, polymer or metal-organic framework material. That is, the desiccant can be a molecular sieve, wherein the molecular sieve still has a relatively high water absorption capacity under the conditions of higher temperature, larger air velocity and lower water content, which is conducive to improving the moisture absorption effect of the desiccant; the desiccant can be silica gel, which is not easy to dissolve, has stable quality and is harmless to the human body, which is conducive to ensuring the long-term stability of the desiccant; the desiccant can be a polymer, which has good water absorption performance and strong water retention capacity, which is conducive to improving the moisture absorption effect of the desiccant; the desiccant can also be a metal-organic framework material, which has the advantages of high porosity, low density, large specific surface area, regular pores, adjustable pore size, and topological structure diversity and tailorability, so as to better ensure the adsorption capacity and adsorption effect of the dehumidification component 2, and at the same time, the metal-organic framework material is not easy to dissolve, which can better improve the long-term temperature of the moisture absorption effect of the desiccant, which is conducive to extending the service life of the dehumidification component 2. In addition, the above materials can desorb water at a certain temperature. For example, the desorption temperature range of molecular sieves is approximately between 120°C and 220°C, and the desorption temperature of MOF is approximately between 80°C and 100°C, which makes the desorption of water adsorbed by molecular sieves and MOFs easy to achieve.

[0050] According to some embodiments of the present invention, the desiccant is a metal-organic framework material, which has a porous structure, can better increase the surface area of ​​the desiccant, and is conducive to improving the hygroscopic capacity and hygroscopic effect of the desiccant, and the metal-organic framework material includes a metal base and an organic ligand. Optionally, the metal base includes at least one of Cr, Al, Zr, Co, Ni, Fe, and Ca elements. In other words, the metal base can include any one of Cr, Al, Zr, Co, Ni, Fe, and Ca elements, and the metal base can also include any multiple of Cr, Al, Zr, Co, Ni, Fe, and Ca elements. There is no specific limitation on the metal elements contained in the metal base. Further optionally, the metal matrix includes Al and / or Zr.

[0051] Optionally, the organic ligand is a multidentate small molecule ligand, and the organic ligand contains at least one of a carboxylic acid group, an N element, and an O element. That is, the organic ligand may contain any one of a carboxylic acid group, an N element, and an O element, or may contain any two of a carboxylic acid group, an N element, and an O element, or may contain a carboxylic acid group, an N element, and an O element at the same time, and the specific composition of the organic ligand is not specifically limited here.

[0052] Optionally, the specific surface area of ​​the desiccant is in the range of 150 to 3000 m2 / g, and the particle size of the desiccant is in the range of 3 nm to 30 um. That is, the specific surface area of ​​the desiccant is controlled within the range of 150 m2 / g to 3000 m2 / g, and the particle size of the desiccant is controlled within the range of 3 nm to 30 um. For example, the specific surface area of ​​the desiccant may be 150 m2 / g, or 300 m2 / g, or 600 m2 / g, or 1000 m2 / g, or 1500 m2 / g, or 2200 m2 / g, or 3000 m2 / g, and the particle size of the desiccant may be 3 nm, or 1 um, or 3 um, or 8 um, or 13 um, or 21 um, or 30 um, and the like, and no specific limitation is made here.

[0053] In a specific example, at 298K, the specific surface area of ​​the desiccant made of the metal-organic framework material is greater than 800㎡ / g, and the bulk density of the metal-organic framework material is 300-700Kg / m 3 , the moisture absorption capacity of the desiccant is greater than 35wt%, which significantly improves the moisture absorption performance of the desiccant.

[0054] According to some optional embodiments of the present invention, the desiccant is a molecular sieve, and the desiccant includes at least one of a 3A molecular sieve, a 4A molecular sieve, a 5A molecular sieve, a NaY molecular sieve, and a 13X molecular sieve. That is to say, the desiccant may include one or more of 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, NaY molecular sieves, and 13X molecular sieves. For example, the desiccant may include only 3A molecular sieves, or 4A molecular sieves, or 5A molecular sieves, or NaY molecular sieves, or 13X molecular sieves; the desiccant may include two molecular sieves of 3A molecular sieves and 4A molecular sieves or other combinations thereof; the desiccant may include three molecular sieves of 3A molecular sieves, 4A molecular sieves, and 5A molecular sieves or other combinations thereof; the desiccant may include four molecular sieves of 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, and NaY molecular sieves or other combinations thereof; the desiccant may include five molecular sieves of 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, and 13X molecular sieves, without specific restrictions. Thus, the flexibility of the desiccant composition can be improved.

[0055] According to some embodiments of the present invention, the dehumidifying element 2 further includes a binder, which is used to bind the desiccant to the rotating part. Thus, the firm connection between the desiccant and the rotating part can be well ensured, thereby preventing the desiccant from falling off the rotating part, and ensuring that the desiccant can stably cycle between adsorption and desorption to achieve continuous dehumidification of the air by the dehumidification module 100.

[0056] In some embodiments, the rotating part is formed into a corrugated structure. The corrugated structure requires less material and has high strength, which can reduce the weight and production cost of the rotating part, and at the same time help to improve the structural strength of the rotating part. In addition, the corrugated structure has a plurality of through holes, which form an airflow channel for airflow to pass through, which can effectively reduce the resistance of the rotating part to the airflow in the adsorption air duct 111.

[0057] In some embodiments, the rotating part is a glass fiber part or a ceramic fiber part. Among them, the glass fiber has strong heat resistance, good corrosion resistance and high mechanical strength, and the ceramic fiber is light in weight, high temperature resistant, good in thermal stability, low in thermal conductivity, small in specific heat and resistant to mechanical vibration. In this way, the service life of the rotating part can be well extended, which is conducive to improving the stability of the dehumidification element 2.

[0058] According to some embodiments of the present invention, the heating element 3 is located on the upstream side of the dehumidifier 2. The “located on the upstream side of the dehumidifier 2” here refers to the direction of gas flow in the desorption duct 112. If the airflow in the desorption duct 112 flows from the front side of the dehumidifier 2 through the dehumidifier 2 to the back side, the heating element 3 is arranged on the front side of the dehumidifier 2. In other words, the airflow driven by the desorption fan 5 is heated by the heating element 3 before passing through the dehumidifier 2. Thus, the airflow located on the upstream side of the dehumidifier 2 can be better heated by the heating element 3, thereby forming hot air blowing to the part of the dehumidifier 2 located in the desorption duct 112, so that the moisture in the desiccant located in the desorption duct 112 can be desorbed into the airflow, and the desorbed moisture is taken away from the dehumidifier by the airflow.

[0059] According to some embodiments of the present invention, the desorption fan 5 and the heating element 3 are located on the same side of the dehumidifier 2 in the axial direction. That is to say, the desorption fan 5 and the heating element 3 are both located on the upstream side of the desorption zone, so that the desorption fan 5 and the heating element 3 can make full use of the installation space on one side of the axial direction of the dehumidifier 2 in the first direction e1, thereby effectively saving the installation space occupied by the desorption fan 5 and the heating element 3 in the axial direction of the dehumidifier 2, and further reducing the size of the dehumidifier module 100 in the axial direction of the dehumidifier 2. In addition, the desorption fan 5 is located on the upstream side of the desorption zone, which can effectively improve the driving force of the desorption fan 5 on the gas in the desorption air duct 112 located in the upstream side area of ​​the dehumidifier 2, thereby ensuring the speed of the hot air passing through the desorption zone while reducing the air volume loss of the desorption fan 5, thereby saving energy and protecting the environment.

[0060] According to some embodiments of the present invention, the dehumidification module 100 further includes a fan installation housing 6 disposed on the mounting frame 1, and the fan installation housing 6 is located on one side of the desorption air duct 112 in the first direction e1 and is located on the same side of the dehumidification component 2 in the axial direction as the heating element 3. In other words, the fan installation housing 6 and the heating element 3 are both located on the upstream side of the desorption zone, so that the fan installation housing 6 and the heating element 3 can make full use of the installation space on one side of the axial direction of the dehumidification component 2 in the first direction e1, thereby better saving the installation space occupied by the desorption fan 5 and the heating element 3 in the axial direction of the dehumidification component 2, which is conducive to controlling the axial size of the dehumidification module 100 in the dehumidification component 2.

[0061] Among them, a mounting cavity 61 and an air supply duct 62 are formed in the fan mounting shell 6, and the desorption fan 5 is arranged in the mounting cavity 61, and the two ends of the air supply duct 62 are respectively connected to the mounting cavity 61 and the desorption duct 112. In other words, the extension direction of the air supply duct 62 has a certain angle with the axial direction of the dehumidifier 2, and the mounting cavity 61 is connected to the desorption duct 112 through the air supply duct 62. The connecting position of the air supply duct 62 and the desorption duct 112 is located on the side of the desorption duct 112 facing the desorption fan 5 in the first direction e1, that is, a connected gas flow channel is formed between the mounting cavity 61, the air supply duct 62 and the desorption duct 112, and the heating element 3 can better increase the gas temperature in the area located on the upstream side of the desorption zone in the desorption duct 112, so that the desorption fan 5 can drive the hot air in the desorption duct 112 to blow to the desorption zone through the mounting cavity 61 and the air supply duct 62, thereby drying the desiccant in the desorption zone.

[0062] In a specific example, the desorption fan 5 is located on the upstream side of the heating element 3, and the mounting frame 1 includes an external frame 12, a first air duct shell 13 and a second air duct shell 14, the first air duct shell 13 and the second air duct shell 14 are both arranged on the external frame 12, the first air duct shell 13 and the second air duct shell 14 are respectively arranged on the axial sides of the dehumidification element 2, and the centers of the axial sides of the dehumidification element 2 are rotatably connected to the first air duct shell 13 and the second air duct shell 14, respectively, the first air duct shell 13 and the second air duct shell 14 both form an air cavity opening toward the dehumidification element 2, the first air duct shell 13 and the second air duct shell 14 jointly define the desorption air duct 112, and the heating element 3 is arranged in the first air duct shell 13, the fan mounting shell 6 is arranged on the external frame 12 and is located on the same side of the dehumidification component 2 as the first air duct shell 13, the fan mounting shell 6 is connected to the side wall of the first air duct shell 13, the side wall here refers to the side wall in the peripheral direction of the first air duct shell 13, the air outlet of the air supply duct 62 is opposite to the heating component 3 in the first direction e1, the heating component 3 is a multi-layered heating wire, the gas in the air supply duct 62 is blown into the heating component 3 along the first direction e1, and the air flow is adjusted through the first air duct shell 13 to flow along the axial direction of the dehumidification component 2 toward the desorption zone, so as to dry the desiccant in the desorption zone by hot air. In addition, reinforcing ribs 15 are formed on the mounting frame 1 to connect the external frame 12 and the second air duct shell 14. The reinforcing ribs 15 are located on the side of the dehumidifier 2 away from the first air duct shell 13 and on the downstream side of the adsorption zone. The reinforcing ribs 15 are provided with multiple circumferential and radial extensions along the dehumidifier 2 to enhance the overall structural strength of the mounting cavity 61. In addition, the cooperation between the reinforcing ribs 15 and the second air duct shell 14 can better support the dehumidifier 2 to prevent the dehumidifier 2 from falling off from the dehumidifier duct 11 when it is impacted by the airflow in the adsorption duct 111. Furthermore, an exhaust port 141 is formed on the second air duct shell 14, and the exhaust port 141 is connected to the desorption duct 112 in the second air duct shell 14. The exhaust port 141 is connected to a recovery device such as a condensing device or an outdoor space to discharge the high-humidity gas in the desorption duct 112.

[0063] According to some optional embodiments of the present invention, the installation cavity 61 and the desorption air duct 112 are arranged along the circumference of the dehumidifier 2. That is, the desorption fan 5 and the desorption air duct 112 are arranged along the circumference of the dehumidifier 2, so that the desorption fan 5 and the desorption air duct 112 can fully utilize the installation space of the dehumidifier module 100 in the circumferential direction of the dehumidifier 2, and at the same time can reduce the installation space occupied by the desorption fan 5 and the desorption air duct 112 in the radial direction of the dehumidifier 2, so that the overall structure of the dehumidifier module 100 is compact and the layout is reasonable.

[0064] Furthermore, in the circumferential direction of the dehumidifier 2, the projection of the ray with the center of the dehumidifier 2 as the endpoint and passing through the center of the mounting cavity 61 on the dehumidifier 2 is L1, and the projection of the ray with the center of the dehumidifier 2 as the endpoint and passing through the center of the desorption duct 112 on the dehumidifier 2 is L2, and the central angle between L1 and L2 is not greater than 90°. In other words, the span of the center of the mounting cavity 61 and the center of the desorption duct 112 relative to the center of the dehumidifier 2 in the circumferential direction of the dehumidifier 2 is controlled within 90°, thereby effectively shortening the distance between the desorption motor and the desorption duct 112 in the axial direction of the dehumidifier 2, thereby effectively shortening the air supply distance of the air supply duct 62, which is beneficial to reducing air volume loss.

[0065] According to some optional embodiments of the present invention, the air outlet of the air supply duct 62 is arranged adjacent to the center of the desorption duct 112 in the radial direction of the dehumidifier 2. That is to say, in the radial direction of the dehumidifier 2, the distance between the air outlet of the air supply duct 62 and the side of the desorption duct 112 close to the center of the dehumidifier 2 is roughly the same as the distance between the air outlet of the air supply duct 62 and the side of the desorption duct 112 away from the center of the dehumidifier 2, so that the air supply duct 62 can discharge the gas to the center position of the desorption duct 112 in the radial direction of the dehumidifier 2, and the air flow entering the desorption duct 112 can be evenly diffused to both sides of the desorption duct 112 along the radial direction of the dehumidifier 2, that is, the uniform distribution of the air field in the desorption duct 112 can be better guaranteed, so that the hot air in the desorption duct 112 can evenly pass through the desorption zone to avoid the poor drying effect caused by the small amount of local hot air in the desorption zone, which is beneficial to improve the drying effect of the hot air in the desorption duct 112 on the desorption zone.

[0066] According to some optional embodiments of the present invention, the projection of the installation cavity 61 on the reference surface is located outside the projection of the dehumidifier 2 on the reference surface, and the reference surface is perpendicular to the axial direction of the dehumidifier 2. In other words, the projection of the installation cavity 61 on the reference surface has no overlapping part with the projection of the dehumidifier 2 on the reference surface, wherein it can be understood that the airflow in the adsorption air duct 111 flows roughly along the axial direction of the dehumidifier 2, thereby, it can be better avoided that the desorption fan 5 blocks the gas flow in the adsorption air duct 111, so as to ensure the smooth flow of the gas in the adsorption air duct 111, which is conducive to improving the dehumidification efficiency of the dehumidifier module 100.

[0067] In a specific example, the projection of the installation cavity 61 on the reference surface is located outside the projection of the dehumidifier 2 on the reference surface, the air outlet of the air supply duct 62 is arranged adjacent to the center of the desorption duct 112 in the radial direction of the dehumidifier 2, and the center angle between L1 and L2 is not greater than 90°. In this way, it is possible to better avoid the fan installation shell 6 forming a partial obstruction of the gas flow in the adsorption duct 111 by the installation cavity 61, and better ensure the uniform distribution of the gas field in the desorption duct 112. At the same time, it is possible to better reduce the distance between the installation cavity 61 and the desorption duct 112 in the circumferential direction of the dehumidifier 2, thereby better shortening the distance of the air supply duct 62, and better reducing the obstruction of the fan installation shell 6 to the adsorption duct 111, so as to ensure the smooth flow of gas in the adsorption duct 111, which is beneficial to improving the dehumidification performance of the dehumidification module 100.

[0068] According to some embodiments of the present invention, the heating element 3 is in a surrounding curved shape. That is to say, the heating element 3 surrounds the desorption air duct 112 and extends in a curved shape. As a result, the area covered by the heating element 3 in the desorption air duct 112 can be increased, and the contact area between the heating element 3 and the gas in the desorption air duct 112 can be increased, so that the heating effect of the heating element 3 on the desorption air duct 112 can be improved, and then the desorption effect of the desiccant in the desorption air duct 112 under the heating of the heating element 3 can be improved, which is conducive to improving the dryness of the desorption of the desiccant.

[0069] According to some optional embodiments of the present invention, the desorption fan 5 includes a motor and an impeller, and the impeller is arranged on the output shaft of the motor, so that the motor drives the impeller to rotate and drives the gas in the installation cavity 61 to flow. The motor and the impeller are arranged along the axial direction of the dehumidification component 2. As a result, the desorption fan 5 can make full use of the installation space of the dehumidification module 100 in the axial direction of the dehumidification component 2, and can better avoid the desorption fan 5 extending to the outer peripheral side of the mounting frame 1 to cause interference, and the layout is reasonable.

[0070] According to some optional embodiments of the present invention, a first gear 41 is provided at the output end of the driving motor 4, and a second gear 21 meshing with the first gear 41 is provided on the outer peripheral wall of the dehumidifying component 2. Thus, through the precise meshing transmission of the first gear 41 and the second gear 21, the rotation speed of the dehumidifying component 2 can be precisely controlled by controlling the rotation speed of the driving motor 4. Among them, if the rotation speed of the dehumidifying component 2 is too fast, the part of the dehumidifying component 2 located in the desorption air duct 112 may not be completely desorbed before entering the adsorption air duct 111, affecting the adsorption effect, while if the rotation speed of the dehumidifying component 2 is too slow, the adsorption area may be saturated and unable to continue to adsorb water vapor, which will also affect the gas dehumidification effect in the adsorption air duct 111. Therefore, by precisely controlling the rotation speed of the dehumidifying component 2, it is beneficial to improve the dehumidification effect of the dehumidification module 100.

[0071] According to some optional embodiments of the present invention, the heating element 3 is an electric heating element. That is, the dehumidification module 100 increases the temperature in the desorption air duct 112 by electric heating to achieve heating of the desiccant in the desorption zone. As a result, the trouble of regularly replenishing the refrigerant can be well avoided, and the electric heating element is less affected by environmental factors such as humidity and temperature, and the heating effect is stable, so that the dehumidification module 100 still has a good dehumidification effect in a low temperature and low humidity environment, which is conducive to improving the application range of the dehumidification module 100.

[0072] According to some embodiments of the present invention, the gas flow directions in the adsorption air duct 111 and the desorption air duct 112 are the same. That is, the direction in which the gas in the adsorption air duct 111 passes through the adsorption zone is consistent with the direction in which the gas in the desorption air duct 112 passes through the desorption zone. As a result, it is possible to better avoid mutual interference between the airflow in the adsorption air duct 111 and the airflow in the desorption air duct 112, thereby better avoiding the gas field disorder in the dehumidification air duct 11, so as to ensure the stable adsorption and desorption of the dehumidification component 2, which is conducive to improving the dehumidification efficiency of the dehumidification module 100.

[0073] According to some embodiments of the present invention, a part of the rotating part is located in the adsorption air duct 111, and another part of the rotating part is located in the desorption air duct 112. That is to say, the rotating part has only two parts located in the adsorption air duct 111 and the desorption air duct 112, respectively. The desiccant on the part of the rotating part located in the adsorption air duct 111 can absorb the water vapor in the adsorption channel 111. Therefore, the part of the rotating part located in the adsorption air duct 111 can be formed as a region where the dehumidifying element 2 adsorbs water vapor in the air. For the convenience of description, it is hereinafter referred to as the adsorption zone. When the gas in the adsorption air duct 111 passes through the adsorption zone, the desiccant in the adsorption zone can better reduce the water vapor content in the gas passing through the adsorption zone, that is, the dehumidification treatment of the gas is achieved. For example, the gas in the indoor space can directly flow into the adsorption air duct 111, and be discharged back to the indoor space after being dehumidified by the adsorption area, thereby realizing the dehumidification treatment of the indoor space; while the desiccant in the adsorption area absorbs the water vapor in the adsorption air duct 111, the desiccant on the rotating part located in the desorption air duct 112 can be desorbed through the cooperation of the heating element 3 and the desorption air duct 5, that is, the rotating part located in the desorption air duct 112 can be formed as the area where the dehumidification element 2 desorbs moisture, which is hereinafter referred to as the desorption area for the convenience of description. In other words, the part of the dehumidifier 2 located in the adsorption air duct 111 is performing adsorption while the part of the dehumidifier 2 located in the desorption air duct 112 is performing desorption, which can better ensure that adsorption and desorption are performed simultaneously on the dehumidifier 2. At the same time, the desiccant in the adsorption area can enter the desorption air duct 112 for desorption after adsorption, and the desiccant in the desorption area can enter the adsorption air duct 111 for adsorption after desorption, which can better reduce the waiting time for adsorption or desorption and better improve the dehumidification efficiency of the dehumidification module 100.

[0074] Specifically, the desorption zone and the adsorption zone are arranged along the axial direction of the dehumidifier 2. After the desiccant in the adsorption zone absorbs water, the rotating part can be rotated so that the part of the rotating part located in the adsorption air duct 111 can be moved to the desorption air duct 112 to desorb the moisture of the desiccant to restore the adsorption capacity of the desiccant. The desiccant after the drying treatment can re-enter the adsorption air duct 111 to absorb moisture as the rotating part rotates.

[0075] In a specific example, the mounting frame 1 includes an external frame 12, a first air duct shell 13 and a second air duct shell 14. A dehumidification air duct 11 is formed in the external frame 12. The cross-section of the dehumidification air duct 11 is circular. The rotating part is disc-shaped and coaxially arranged with the dehumidification air duct 11. The desiccant is evenly distributed on the rotating part. The driving motor 4 is arranged on the external frame 12 and is located on the outer peripheral side of the dehumidification air duct 11. The driving motor 4 and the rotating part are connected by a first gear 41 and a second gear 21. A desorption air duct 112 is formed between the first air duct shell 13 and the second air duct shell 14. The cross-section of the desorption air duct 112 is fan-shaped. The inner peripheral wall of the dehumidification air duct 11 and the side walls of the first air duct shell 13 and the second air duct shell 14 jointly define an adsorption air duct 111. The desorption air duct 112 and the adsorption air duct 111 together constitute the dehumidification air duct 11.

[0076] According to some embodiments of the present invention, the projection of the desorption duct 112 on the reference plane is fan-shaped, the reference plane is perpendicular to the axial direction of the dehumidification component 2, and the central angle α of the projection of the desorption duct 112 on the reference plane satisfies: 45°≤α≤120°. That is, the central angle of the portion of the dehumidification component 2 located in the desorption duct 112 is controlled between 45° and 120°, such as the central angle of the portion of the dehumidification component 2 located in the desorption duct 112 can be 45°, or 60°, or 80, or 105, or 120°, etc., and no specific restrictions are made here. It can be understood that the larger the central angle of the portion of the dehumidifier 2 located in the desorption air duct 112, the more the portion of the dehumidifier 2 located in the desorption air duct 112, the larger the desorption area, and the smaller the portion of the dehumidifier 2 located in the adsorption air duct 111, the smaller the adsorption area; conversely, the smaller the central angle of the portion of the dehumidifier 2 located in the desorption air duct 112, the less the portion of the dehumidifier 2 located in the desorption air duct 112, the smaller the desorption area, and the more the portion of the dehumidifier 2 located in the adsorption air duct 111, the larger the adsorption area. The larger the desorption area, the more moisture the dehumidifier 2 can desorb per unit time, and the larger the adsorption area, the more moisture the dehumidifier 2 can adsorb per unit time. Therefore, by controlling the central angle of the portion of the dehumidifier 2 located in the desorption air duct 112 to be between 45° and 120°, it is possible to better avoid the desorption zone being too small, which would affect the amount of water desorbed by the dehumidifier 2 per unit time and cause incomplete desorption. At the same time, it is possible to better avoid the adsorption zone being too small, which would affect the amount of water vapor adsorbed by the dehumidifier 2 per unit time. That is, while ensuring that the desorption zone can completely desorb water, the amount of water vapor adsorbed by the adsorption zone is also ensured, thereby facilitating the realization of the adsorption-desorption dynamic balance of the dehumidifier 2. The adsorption-desorption dynamic balance here means that part of the water adsorbed on the dehumidifier 2 can be completely desorbed after entering the desorption air duct 112, and the part of the dehumidifier 2 located in the desorption air duct 112 can immediately enter the adsorption air duct 111 for continued adsorption after desorption.

[0077] Preferably, the central angle α of the projection of the desorption air duct 112 on the reference surface satisfies: 60≤α≤65°.

[0078] According to some embodiments of the present invention, the rotation speed n of the dehumidifier 2 satisfies: 0.1RPM≤n≤3RPM. That is, the rotation speed of the dehumidifier 2 driven by the driving motor 4 is controlled between 0.1 rpm and 3 rpm, such as the rotation speed of the dehumidifier 2 can be 0.1 rpm, or 0.5 rpm, or 1 rpm, or 2 rpm, or 3 rpm, etc., which are not limited here. In this way, it can be better avoided that the part of the dehumidifier 2 located in the desorption air duct 112 enters the adsorption air duct 111 after not being completely desorbed due to the excessive rotation speed of the dehumidifier 2, and at the same time, it can be better avoided that the desiccant in the adsorption zone cannot continue to adsorb after being saturated due to the excessively slow rotation speed of the dehumidifier 2, that is, while ensuring that the desiccant in the desorption zone can completely desorb moisture, the amount of water vapor adsorbed by the desiccant in the adsorption zone is guaranteed, thereby facilitating the realization of the adsorption-desorption dynamic balance of the dehumidifier 2.

[0079] Preferably, the rotation speed n of the dehumidifying element 2 satisfies: 0.6RPM≤n≤1RPM.

[0080] According to some embodiments of the present invention, the wind speed U of the adsorption air duct 111 satisfies: 0.1≤U≤2m / s. That is, the wind speed in the adsorption air duct 111 is controlled between 0.1 meters per second and 2 meters per second. For example, the wind speed in the adsorption air duct 111 can be 0.1 meters per second, or 0.4 meters per second, or 1 meter per second, or 1.5 meters per second, or 2 meters per second, etc., without specific restrictions here. Among them, the faster the wind speed in the adsorption air duct 111, the more air volume enters the adsorption air duct 111 and passes through the dehumidification component 2 per unit time, and the higher the dehumidification efficiency of the dehumidification module 100. However, when the adsorption capacity of the desiccant in the adsorption zone is constant, when the wind speed in the adsorption air duct 111 has made the desiccant in the adsorption zone in a saturated state, the increase in the wind speed in the adsorption air duct 111 has little effect on the dehumidification efficiency of the dehumidification module 100. In this way, the dehumidification efficiency of the dehumidification module 100 can be better avoided due to the slow wind speed in the adsorption air duct 111. While ensuring the dehumidification efficiency of the dehumidification module 100, the excessive power consumption of the driving motor 4 can be avoided to cause energy waste, which is energy-saving and environmentally friendly.

[0081] Preferably, the wind speed U of the adsorption air duct 111 is 1.25 m / s. That is, the wind speed threshold in the adsorption air duct 111 is 1.25 m / s. Before the wind speed in the adsorption air duct 111 reaches 1.25 m / s, the faster the wind speed, the higher the adsorption amount of water vapor by the dehumidifier 2. After the wind speed in the adsorption air duct 111 reaches 1.25 m / s, the increase in wind speed has little effect on the moisture absorption amount of the dehumidifier 2, thereby avoiding unnecessary power consumption waste of the drive motor 4 and high-speed rotation noise, etc., which is energy-saving and environmentally friendly and helps to improve the comfort of use of the dehumidifier module.

[0082] According to some embodiments of the present invention, the air volume range of the desorption fan 5 is 2-100m3 / h. That is, the air volume range of the desorption fan 5 is controlled within 2m 3 / h to 100m 3 / h, for example, the air volume range of the desorption fan 5 can be 2m 3 / h, or 10m 3 / h, or 20m 3 / h、35m 3 / h, or 65m 3 / h, or 100m 3 / h, no specific restrictions are made here. Thus, it is possible to better avoid the air volume of the desorption air duct 5 being too small, resulting in the gas flow rate in the desorption air duct 112 being too slow to affect the desorption effect of the desiccant, and it is possible to ensure that the air volume of the desorption fan 5 meets the desorption requirements of the desiccant while avoiding the noise and increased energy consumption caused by the excessive air volume of the desorption fan 5.

[0083] In a specific example, when the air environment is 27°C and RH (relative humidity) is 60%, the wind speed in the adsorption duct 111 is 1.25 meters per second, the rotation speed of the dehumidification component 2 is controlled between 0.6 revolutions per minute and 1 revolution per minute, and the central angle of the part of the dehumidification component 2 located in the desorption duct 112 is controlled between 60° and 65°, the dehumidification module 100 has the best dehumidification efficiency and can achieve the adsorption-desorption dynamic balance of the dehumidification component 2.

[0084] A dehumidifier according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0085] The dehumidifier according to the embodiment of the present invention comprises: a dehumidification module 100 and an adsorption fan, wherein the adsorption fan is used to drive the gas flow in the adsorption air duct 111 of the dehumidification module 100. Thus, the gas flow speed in the adsorption air duct 111 can be better accelerated by the adsorption fan, so that the air volume of the gas passing through the adsorption air duct 111 can be increased, and then the air dehumidification efficiency of the dehumidification element can be improved.

[0086] According to the dehumidifier of the embodiment of the present invention, the dehumidification element 2 is rotatably arranged in the dehumidification air duct 11, and the dehumidification air duct 11 includes an adsorption air duct 111 and a desorption air duct 112 arranged along the circumferential direction. A heating element 3 is provided in the desorption air duct 112. The rotation of the rotating part drives the desiccant to move between the adsorption air duct 111 and the desorption air duct 112, so that the desiccant can be cycled in adsorption and desorption, and the continuous dehumidification capacity is strong. At the same time, the desorption fan 5 and the heating element 3 are arranged along the first direction e1 perpendicular to the axial direction of the dehumidification element 2, so that the axial size of the dehumidification module 100 in the dehumidification element 2 can be better controlled, which is beneficial to reduce the installation space occupied by the dehumidification module 100.
