Description

Technical Field

[0001] The invention relates to the technical field of air treatment, and in particular to a dehumidification wheel desorption module and dehumidification equipment. Background Art

[0002] With the improvement of people's quality of life and the progress of industrial development, dehumidification technology has become increasingly important. At present, condensation dehumidification and rotary dehumidification are more widely used. Among them, rotary dehumidifiers are energy-saving and environmentally friendly because they do not use compressors and refrigerants, are adaptable to a variety of environments, and are chosen by more and more dehumidification occasions. The working principle of the dehumidification rotary machine is to divide the rotary wheel into a moisture absorption zone and a regeneration zone. After the moisture in the air is removed in the moisture absorption zone, the dry air is sent into the room, and the rotary wheel that has absorbed moisture moves to the regeneration zone. At this time, the regenerated air sent in from the reverse direction is sent to the heater through the pipeline for heating, and then the hot air is continued to be sent to the rotary wheel through the pipeline to drive out moisture, so that the rotary wheel continues to work, the dehumidification rotary wheel continues to rotate, and the moisture absorption and regeneration action is continuously repeated, thereby providing dry air.

[0003] The demand for miniaturization and flattening of products is getting louder and louder. The overall thickness of the rotary dehumidification module is being compressed to the limit. In addition to the thickness of the rotor itself, the thickness of the desorption pipe and the heating module are the main factors affecting the overall rotary dehumidification module. At present, in order to reduce the overall thickness, the heater is installed on the rotor. This setting will affect the temperature rise of the regenerated air and reduce the desorption efficiency. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that a heater is installed on a rotary wheel in order to reduce the thickness of the product, which affects the temperature rise of the regenerated air and leads to reduced desorption efficiency, thereby providing a dehumidification rotary desorption module and dehumidification equipment.

[0020] Optionally, after the supplementary heating plate rotates into the desorption zone, the supplementary heating plate is arranged in the heat preservation transfer cavity.

[0021] Optionally, it also includes:

[0022] A supplementary air inlet shell, comprising at least one group, wherein the supplementary air inlet shell and the air inlet shell are stacked and arranged along the axial direction of the dehumidification rotor; the supplementary air inlet shell and the air inlet shell are arranged to rotate relative to each other, and the supplementary air inlet shell can be rotated from the desorption area to the adsorption area by driving, and a third air inlet is arranged on the supplementary air inlet shell;

[0025] Optionally, it also includes:

[0026] An air outlet shell is covered on the other side of the desorption zone. The dehumidification wheel and the air outlet shell are relatively rotatable. An air outlet channel is formed between the air outlet shell and the dehumidification wheel. An air outlet is arranged on the air outlet shell.

[0027] Optionally, the heating plate is an electric heating wire coil heating plate or a heating film.

[0028] The present invention also provides a dehumidification device, comprising the dehumidification wheel desorption module described in any one of the above items.

[0029] The technical solution of the present invention has the following advantages:

[0030] 1. The dehumidification wheel desorption module provided by the present invention comprises a dehumidification wheel, an air inlet shell and a heating plate. The dehumidification wheel has an adsorption zone and a desorption zone. The adsorption zone is used to remove moisture from the air. After the wheel rotates to the desorption zone, the moisture in the wheel is removed. The air inlet shell cover is arranged on one side of the desorption zone to form an air inlet channel of the desorption zone. A temperature buffer cavity is formed between the heating plate and the side wall where the first air inlet is located. A heat preservation transfer cavity is formed between the heating plate and the dehumidification wheel. After the air passes through the temperature buffer cavity, the heating plate and the heat preservation transfer cavity in sequence, it enters the dehumidification wheel to remove moisture. The air inlet shell and the heating plate cooperate to form an ultra-thin desorption module.

[0031] The setting of the temperature buffer chamber increases the temperature of the space between the heating plate and the air inlet shell, so that the wind mixes with the higher temperature in the cavity when entering, increases the temperature starting point of the wind passing through the heating plate, reduces the energy difference when the temperature reaches the boiling point, and at the same time increases the movement time of the wind from the air inlet shell to the surface of the dehumidification wheel, providing a time basis for the wind to absorb more heat, so that the working temperature of the heating plate can be reduced without reducing the desorption effect; and with the existence of the temperature buffer chamber, the temperature of the air inlet shell can be greatly reduced, which plays a safe protection effect against overheating and avoids a large amount of energy consumption in the temperature rise of the air inlet shell, resulting in energy waste and safety hazards of the air inlet shell; the setting of the thermal insulation transfer chamber increases the movement time of the wind from the heating plate to the surface of the dehumidification wheel. Like the temperature buffer chamber, it also provides a time basis for the wind to absorb more heat, does not cause heat waste, and further improves the desorption efficiency of the dehumidification wheel.

[0032] 2. In the dehumidification wheel desorption module provided by the present invention, the depth D2 of the heat preservation transfer chamber is greater than or equal to the depth D1 of the temperature buffer chamber. The temperature buffer chamber plays a preheating role for the temperature rise of the air, and the heat preservation transfer chamber further increases the temperature of the air, giving the air sufficient heating residence time, thereby ensuring that the temperature requirement of the air is met when it reaches the dehumidification wheel.

[0033] 3. The dehumidification wheel desorption module provided by the present invention calculates the temperature of the air inlet shell when the heating plate is working according to the working temperature of the heating plate, the depth of the temperature buffer cavity and the desorption wind speed of the dehumidification wheel, and adjusts the parameters to avoid safety hazards caused by excessively high temperature of the air inlet shell. At the same time, the relationship between the thickness of the temperature buffer cavity and the temperature of the air inlet shell also ensures that the temperature rise of the air in the air inlet channel meets the temperature requirement for desorption.

[0034] 4. The dehumidification wheel desorption module provided by the present invention also includes a supplementary heating plate, which is stacked with the heating plate and rotated relative to the heating plate. The supplementary heating plate can be driven to rotate from the adsorption zone to the desorption zone. When the water content of the dehumidification wheel is too high, making it impossible for the dehumidification wheel to desorb all the water in the desorption zone, the supplementary heating plate is transferred to the adsorption zone in advance, and the water in the dehumidification wheel is preheated in advance, so that it can quickly and thoroughly complete desorption under high temperature after entering the desorption zone. Different gears are set according to different water contents to improve the desorption efficiency.

[0035] 5. In the dehumidification wheel desorption module provided by the present invention, after the supplementary heating plate is rotated into the desorption zone, the supplementary heating plate is arranged in the heat preservation transfer cavity. The characteristic that the thickness of the heat preservation transfer cavity itself is greater than that of the temperature buffer cavity can be utilized, so that the overall thickness will not be greatly affected after the supplementary heating plate is added.

[0036] 6. The dehumidification wheel desorption module provided by the present invention also includes a supplementary air inlet shell and a supplementary heating plate. The supplementary heating plate is arranged in the supplementary air inlet shell. The supplementary air inlet shell and the air inlet shell are stacked along the axial direction of the dehumidification wheel. The supplementary air inlet shell and the air inlet shell are relatively rotatable. The supplementary air inlet shell can be driven to rotate from the adsorption zone to the desorption zone. When the moisture content of the dehumidification wheel is too high, so that the dehumidification wheel cannot completely dehumidify in the desorption zone, the supplementary air inlet shell drives the supplementary heating plate to be rotated to the adsorption zone in advance, and the moisture in the dehumidification wheel is preheated in advance, so that it can quickly and thoroughly complete desorption under high temperature after entering the desorption zone. Different gears are set according to different moisture contents to improve the desorption efficiency.

[0037] 7. In the dehumidification wheel desorption module provided by the present invention, the supplementary air inlet shell is arranged in the heat preservation transfer cavity to avoid excessive increase in the thickness of the overall structure. The gap between the side wall where the third air inlet is located and the supplementary heating plate ensures the preheating effect of the supplementary air inlet shell and the supplementary heating plate on the moisture after rotating to the adsorption area.

[0038] 8. The dehumidification wheel desorption module provided by the present invention also includes an air outlet shell, an air outlet channel is formed between the air outlet shell and the dehumidification wheel, and an air outlet is arranged on the air outlet shell. The arrangement of the air outlet shell ensures the overall thickness requirement, making the overall structure compact.

[0039] 9. The dehumidification wheel desorption module provided by the present invention has a heating plate which is an electric heating wire coil heating plate or a heating film, which has good thermal conductivity, and its thickness also provides the possibility for the dehumidification wheel desorption module to be more ultra-thin.

[0040] 10. The dehumidification equipment provided by the present invention includes a dehumidification wheel desorption module, which has an ultra-thin configuration and a high desorption efficiency, making the dehumidification equipment easier to be miniaturized and flattened.

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

[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] First embodiment

[0058] The dehumidification wheel desorption module provided in this embodiment is used to be arranged in a dehumidification device, and can achieve a flat and ultra-thin arrangement and a higher desorption efficiency.

[0059] like Figures 1 to 3As shown, a specific implementation manner of the dehumidification wheel desorption module provided in this embodiment includes a dehumidification wheel 1, an air inlet shell 5 and a heating plate 7, the dehumidification wheel 1 has an adsorption area 2 and a desorption area 3; the air inlet shell 5 is covered on one side of the desorption area 3, an air inlet channel is formed between the air inlet shell 5 and the dehumidification wheel 1, the dehumidification wheel 1 and the air inlet shell 5 are arranged to rotate relative to each other, and a first air inlet 6 is arranged on the air inlet shell 5; the heating plate 7 is arranged in the air inlet channel, a temperature buffer cavity 8 is formed between the side wall where the first air inlet 6 is located and the heating plate 7, a heat preservation transfer cavity 9 is formed between the heating plate 7 and the dehumidification wheel 1, and a second air inlet 10 is arranged on the heating plate 7.

[0060] The adsorption zone 2 is used to remove moisture from the air. After the dehumidification wheel 1 rotates to the desorption zone 3, the moisture in the dehumidification wheel 1 is removed. After the air enters the air inlet channel, it passes through the temperature buffer chamber 8, the heating plate 7 and the heat preservation transfer chamber 9 in sequence and then enters the dehumidification wheel 1 for moisture removal. The cooperation of the air inlet shell 5 and the heating plate 7 forms an ultra-thin desorption module; the setting of the temperature buffer chamber 8 increases the temperature of the space between the heating plate 7 and the air inlet shell 5, so that the wind mixes with the higher temperature in the cavity when entering, increases the temperature starting point of the wind passing through the heating plate 7, reduces the energy difference when the temperature reaches the boiling point, and at the same time increases the movement of the wind from the air inlet shell 5 to the surface of the dehumidification wheel 1. The movement time provides a time basis for the wind to absorb more heat, so that the working temperature of the heating plate 7 can be reduced without reducing the desorption effect; and with the existence of the temperature buffer chamber 8, the temperature of the air inlet shell 5 can be greatly reduced, which plays a safe protection effect against overheating and avoids a large amount of energy consumption in the temperature rise of the air inlet shell 5, resulting in energy waste and safety hazards of the air inlet shell 5; the setting of the heat preservation transfer chamber 9 increases the movement time of the wind from the heating plate 7 to the surface of the dehumidification wheel 1. Like the temperature buffer chamber 8, it also provides a time basis for the wind to absorb more heat, does not cause heat waste, and further improves the desorption efficiency of the dehumidification wheel 1.

[0061] Specifically, the dehumidification wheel 1 can be set on the supporting shaft and continuously rotate around the supporting shaft to realize the adsorption and desorption process. The adsorption zone 2 can occupy three quarters of the area of ​​the dehumidification wheel 1, and the desorption zone 3 can occupy one quarter of the area of ​​the dehumidification wheel. The air inlet shell 5 includes a connected fan-shaped plate and an arc plate. The end of the fan-shaped plate is fixedly connected to the supporting shaft. The arc plate is arranged on the side wall of the dehumidification wheel 1 to form an air inlet channel between the fan-shaped plate and the dehumidification wheel 1; the first air inlet 6 on the air inlet shell 5 can be a circular hole arranged in an array, and the heating plate 7 can be a fan-shaped structure adapted to the structure of the desorption zone 3. The second air inlet 10 thereon can be a circular hole arranged in an array, and corresponds one-to-one with the first air inlet 6 to reduce wind resistance. In addition, the second air inlet 10 can also be set as a strip hole structure.

[0062] like Figure 3As shown, for the desorption module of the dehumidification wheel provided in this embodiment, the depth of the temperature buffer chamber 8 is D1, and the depth of the heat preservation transfer chamber 9 is D2, where D2 ≥ D1. For the heating of air, the temperature buffer chamber 8 plays a role in preheating, while the heat preservation transfer chamber 9 further increases the temperature of the air, providing sufficient heating residence time for the air and ensuring the temperature requirement of the air when it reaches the dehumidification wheel.

[0063] For the desorption module of the dehumidification wheel provided in this embodiment, the temperature of the air inlet housing 5 when the heating sheet 7 is working is calculated according to the working temperature of the heating sheet 7, the depth of the temperature buffer chamber 8, and the desorption air velocity of the dehumidification wheel 1. The calculation formula is as follows:

[0064]

[0065] Wherein, T is the working temperature of the heating sheet 7;

[0066] T1 is the temperature of the air inlet housing 5 when the heating sheet 7 is working;

[0067] D1 is the depth of the temperature buffer chamber 8;

[0068] V is the desorption air velocity of the dehumidification wheel 1;

[0069] C is the correction coefficient.

[0070] According to parameter adjustment, the potential safety hazard caused by too high temperature of the air inlet housing 5 is avoided. At the same time, the relationship between the thickness of the temperature buffer chamber 8 and the temperature of the air inlet housing 5 also ensures that the heating of the air in the air inlet channel meets the temperature requirement for desorption. In different environments, the moisture content in the air and some other substances, such as high salt content by the sea, etc., lead to different energy requirements for air heating. Therefore, the setting of the correction coefficient makes the calculation more accurate.

[0071] Generally, 0.5mm < D1 < 5mm, the heating sheet temperature 95°C < T1 < 195°C, and the desorption air velocity 0.1m / s < V < 3m / s.

[0072] As Figure 8 shown, the desorption module of the dehumidification wheel provided in this embodiment further includes an air outlet housing 15, which is covered on the other side of the desorption area 3. The dehumidification wheel 1 and the air outlet housing 15 are relatively rotatably arranged, and an air outlet channel is formed between the air outlet housing 15 and the dehumidification wheel 1. An air outlet 14 is provided on the air outlet housing 15. The setting of the air outlet housing 15 ensures the overall thickness requirement, making the overall structure compact. The structure of the air outlet housing 15 can be the same as that of the air inlet housing 5, ensuring that the product tends to be flatter.

[0073] The heating plate 7 provided in this embodiment is an electric heating wire coil heating plate or a heating film, which has good thermal conductivity, and its thickness also provides the possibility for the dehumidification wheel desorption module to be more ultra-thin.

[0074] Second embodiment

[0075] like Figures 4 to 5 As shown, the dehumidification wheel desorption module provided in this embodiment includes a dehumidification wheel 1, an air inlet shell 5 and a heating plate 7, the dehumidification wheel 1 has an adsorption area 2 and a desorption area 3; the air inlet shell 5 is covered on one side of the desorption area 3, an air inlet channel is formed between the air inlet shell 5 and the dehumidification wheel 1, the dehumidification wheel 1 and the air inlet shell 5 are relatively rotatably arranged, and a first air inlet 6 is arranged on the air inlet shell 5; the heating plate 7 is arranged in the air inlet channel, a temperature buffer cavity 8 is formed between the side wall where the first air inlet 6 is located and the heating plate 7, a heat preservation transfer cavity 9 is formed between the heating plate 7 and the dehumidification wheel 1, and a second air inlet 10 is arranged on the heating plate 7;

[0076] It also includes a supplementary heating plate 4, which has at least one group. The supplementary heating plate 4 is arranged in the air inlet channel, and the supplementary heating plate 4 and the heating plate 7 are stacked along the axial direction of the dehumidification wheel 1. The supplementary heating plate 4 is provided with a fourth air inlet 13; the supplementary heating plate 4 and the heating plate 7 are arranged to rotate relative to each other, and the supplementary heating plate 4 can be driven to rotate from the desorption zone 3 to the adsorption zone 2.

[0077] When the moisture content of the dehumidification wheel 1 is too high, so that the dehumidification wheel 1 cannot completely dehumidify in the desorption zone 3, the supplementary heating plate 4 is transferred to the adsorption zone 2 in advance, and the moisture in the dehumidification wheel 1 is preheated and heated in advance, so that it can quickly and thoroughly complete the desorption under high temperature after entering the desorption zone 3. Different gears are set according to different moisture contents to improve the desorption efficiency. Among them, the supplementary heating plate 4 can be the same shape as the heating plate 7, and the fourth air inlet 13 on the supplementary heating plate 4 can be arranged opposite to the second air inlet 10 on the heating plate 7 to reduce wind resistance. The supplementary heating plate 4 can be driven by a motor or by an electric rotating disk arranged on the supporting shaft. The outer side of the supplementary heating plate 4 is slidably arranged with the arc plate of the air inlet shell 5, and a sliding groove can be arranged on the arc plate. The outer side of the supplementary heating plate 4 is arranged in the sliding groove, so that the supplementary heating plate 4 is more stable during the rotation process, and the degree of rotation of the supplementary heating plate 4 is set according to the moisture content in the dehumidification wheel 1.

[0078] like Figure 5As shown, in the dehumidification wheel desorption module provided in this embodiment, after the supplementary heating sheet 4 rotates into the desorption zone 3, the supplementary heating sheet 4 is arranged in the heat preservation transfer chamber 9. The characteristic that the thickness of the heat preservation transfer chamber 9 itself is greater than that of the temperature buffer chamber 8 can be utilized, so that the overall thickness will not be greatly affected after the supplementary heating sheet 4 is added. In addition, as an alternative embodiment, the supplementary heating sheet 4 can also be arranged in the temperature buffer chamber 8.

[0079] like Figure 8 As shown, the dehumidification wheel desorption module provided in this embodiment further includes an air outlet housing 15, which is covered on the other side of the desorption zone 3, the dehumidification wheel 1 and the air outlet housing 15 are arranged to rotate relative to each other, an air outlet channel is formed between the air outlet housing 15 and the dehumidification wheel 1, and an air outlet 14 is arranged on the air outlet housing 15. The arrangement of the air outlet housing 15 ensures the overall thickness requirement, making the overall structure compact, and the structure of the air outlet housing 15 can be the same as that of the air inlet housing 5, ensuring that the product is more inclined to a flat arrangement.

[0080] The heating plate 7 provided in this embodiment is an electric heating wire coil heating plate or a heating film, which has good thermal conductivity, and its thickness also provides the possibility for the dehumidification wheel desorption module to be more ultra-thin.

[0081] When the supplementary heating plate 4 rotates, there must be space on the partition between the adsorption zone 2 and the desorption zone 3 for its rotation, which may cause the air on both sides to mix with each other and affect the dehumidification effect. A flexible seal can be set in the space, such as a sealing brush, which will not affect the rotation of the supplementary heating plate 4 and also achieve a sealed separation between the two areas.

[0082] The air inlet shell 5 and the air outlet shell 15 may be made of plastic materials such as heat-resistant PP, heat-resistant PC, and heat-resistant PET.

[0083] Third embodiment

[0084] like Figure 6 to Figure 7 As shown, the dehumidification wheel desorption module provided in this embodiment includes a dehumidification wheel 1, an air inlet shell 5 and a heating plate 7, the dehumidification wheel 1 has an adsorption area 2 and a desorption area 3; the air inlet shell 5 is covered on one side of the desorption area 3, an air inlet channel is formed between the air inlet shell 5 and the dehumidification wheel 1, the dehumidification wheel 1 and the air inlet shell 5 are relatively rotatably arranged, and a first air inlet 6 is arranged on the air inlet shell 5; the heating plate 7 is arranged in the air inlet channel, a temperature buffer cavity 8 is formed between the side wall where the first air inlet 6 is located and the heating plate 7, a heat preservation transfer cavity 9 is formed between the heating plate 7 and the dehumidification wheel 1, and a second air inlet 10 is arranged on the heating plate 7;

[0085] It also includes a supplementary air inlet shell 11 and a supplementary heating plate 4, the supplementary air inlet shell 11 has at least one group, the supplementary air inlet shell 11 and the air inlet shell 5 are stacked along the axial direction of the dehumidification wheel 1; the supplementary air inlet shell 11 and the air inlet shell 5 are relatively rotatable, the supplementary air inlet shell 11 can be driven to rotate from the desorption area 3 to the adsorption area 2, and a third air inlet port 12 is provided on the supplementary air inlet shell 11; the supplementary heating plate 4 is arranged in the supplementary air inlet shell 11, and the rotation of the supplementary air inlet shell 11 drives the supplementary heating plate 4 to rotate, and a fourth air inlet port 13 is provided on the supplementary heating plate 4.

[0086] When the moisture content of the dehumidification wheel 1 is too high, making it impossible for the dehumidification wheel 1 to completely dehumidify in the desorption zone 3, the supplementary air inlet shell 11 drives the supplementary heating plate 4 to rotate to the adsorption zone 2 in advance. The supplementary air inlet shell 11 constructs a heating space to preheat the moisture in the dehumidification wheel 1 in advance, so that it can quickly and thoroughly complete the desorption under high temperature after entering the desorption zone 3. Different gears are set according to different moisture contents to improve the desorption efficiency.

[0087] Specifically, after the supplementary air inlet shell 11 rotates to the desorption zone 3, the first air inlet 6, the second air inlet 10, the third air inlet 12 and the fourth air inlet 13 are all arranged relatively to each other, the structure of the supplementary air inlet shell 11 is the same as that of the air inlet shell 5, and they are arranged to rotate relatively, the supplementary heating plate 4 is fixedly set in the supplementary air inlet shell 11, and rotates with the supplementary air inlet shell 11, and the supplementary air inlet shell 11 can be driven by a motor, and can also be driven by an electric rotating disk set on the supporting shaft.

[0088] like Figure 7 As shown, in the dehumidification wheel desorption module provided in this embodiment, after the supplementary air inlet shell 11 rotates to the desorption zone 3, the supplementary air inlet shell 11 is arranged in the heat preservation transfer cavity 9, and there is a gap between the side wall where the third air inlet 12 is located and the supplementary heating plate 4. To avoid excessive increase in the thickness of the overall structure, the gap between the side wall where the third air inlet 12 is located and the supplementary heating plate 4 ensures the preheating effect of the supplementary air inlet shell 11 and the supplementary heating plate 4 on the moisture after rotating to the adsorption zone 2.

[0089] like Figure 8 As shown, the dehumidification wheel desorption module provided in this embodiment further includes an air outlet housing 15, which is covered on the other side of the desorption zone 3, the dehumidification wheel 1 and the air outlet housing 15 are arranged to rotate relative to each other, an air outlet channel is formed between the air outlet housing 15 and the dehumidification wheel 1, and an air outlet 14 is arranged on the air outlet housing 15. The arrangement of the air outlet housing 15 ensures the overall thickness requirement, making the overall structure compact, and the structure of the air outlet housing 15 can be the same as that of the air inlet housing 5, ensuring that the product is more inclined to a flat arrangement.

[0090] The heating plate 7 provided in this embodiment is an electric heating wire coil heating plate or a heating film, which has good thermal conductivity, and its thickness also provides the possibility for the dehumidification wheel desorption module to be more ultra-thin.

[0091] When the supplementary air inlet shell 11 rotates, there must be space on the partition between the adsorption area 2 and the desorption area 3 for its rotation, which may cause the air on both sides to mix with each other and affect the dehumidification effect. A flexible seal can be set in the space, such as a sealing brush, which will not affect the rotation of the supplementary air inlet shell 11 and also achieve a sealed separation between the two areas.

[0092] Among them, the material of the air inlet shell 5, the supplementary air inlet shell 11 and the air outlet shell 15 can be heat-resistant PP, heat-resistant PC, heat-resistant PET and other plastic materials.

[0093] Fourth embodiment

[0094] This embodiment provides a dehumidification device, including the dehumidification wheel desorption module described in any of the above embodiments. Specifically, the dehumidification device can be a bathroom heater, and the ultra-thin configuration and high desorption efficiency make the dehumidification device easier to be compact and flat.

[0095] When the dehumidification wheel desorption module is installed in the bathroom heater, the installation position of the rotary dehumidification wheel desorption module is usually on the mask, or between the mask and the wind collecting plate. The mask has an air inlet. If the wind directions of the adsorption zone 2 and the desorption zone 3 are opposite, it is necessary to establish an additional exhaust channel between the mask and the rotary dehumidification desorption module. The mask faces the room. Therefore, on the bathroom heater product, the wind directions of the adsorption zone 2 and the desorption zone 3 are set to be the same.

[0096] like Fig. 9 As shown, the working process of the dehumidification wheel desorption module is as follows: in order to reduce the overall size of the dehumidification equipment, the air inlet direction of the adsorption process can be the same as the air inlet direction of the desorption process. After the indoor air with moisture passes through the adsorption zone 2, the moisture in the air is removed by the dehumidification wheel 1, and the dry air is sent into the room; the dehumidification wheel 1 that has absorbed moisture rotates to the desorption zone 3, and the regenerated air is heated and then passes through the dehumidification wheel 1 to remove moisture, and the air with moisture is discharged to the outside. After the moisture is removed, the dehumidification wheel 1 continues to rotate to the adsorption zone 2 for adsorption work.

[0097] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
