Abstract
Description
Technical Field
[0001] This invention relates to the field of ventilation equipment technology, and more particularly to a ventilation device with humidity regulation. Background Technology
[0002] Ventilation equipment, as a key component in maintaining indoor air quality, has become an indispensable infrastructure in modern buildings and industrial facilities. Traditional ventilation equipment primarily focuses on air exchange and circulation, maintaining basic indoor air quality by introducing fresh outdoor air and expelling stale indoor air. However, as people's demands for indoor environmental quality have increased, simple air exchange is far from sufficient to meet comfort and health needs, leading to the development of ventilation equipment with humidity control functions.
[0003] Existing ventilation equipment with humidity control typically incorporates a spray system for humidification and a dehumidifying impeller for dehumidification. The dehumidifying impeller, a core technology in dehumidification applications, is used in various industries such as lithium battery production, semiconductor and electronics manufacturing, pharmaceutical production, and food processing. The impeller is usually composed of a high-temperature resistant ceramic fiber carrier and a highly hygroscopic material. When humid air passes through the impeller, the moisture in the air is absorbed, resulting in dry air.
[0004] Dehumidifier rotors are typically divided into a treatment zone and a regeneration zone. The treatment zone dries humid air, while hot air blown through the regeneration zone restores the rotor's dryness and moisture-absorbing capacity. In existing dehumidifier rotors, the airflow direction remains constant in both the treatment and regeneration zones. However, since the treatment zone is usually several times the size of the regeneration zone, the rotor is constantly situated in the treatment zone, and the continuous flow of air in the same direction causes uneven stress on the rotor's internal structure.
[0005] For example, the patent with authorization announcement number CN220287627U discloses a household rotary dehumidifier. The dehumidifier includes a dehumidification shell, inside which is a dehumidification rotor, a first ventilation duct for dehumidification, and a second ventilation duct for regeneration. The dehumidification rotor is provided with a processing zone and a regeneration zone. The processing zone is located in the first ventilation duct, and the regeneration zone is located in the second ventilation duct. The air outlet side of the processing zone and the air inlet side of the regeneration zone are located on the same side. A main fan is provided in the first ventilation duct, and the main fan is located on the air outlet side of the processing zone. A humidity sensor is provided on the air outlet side of the processing zone. The main fan is a stepless speed-regulating centrifugal fan.
[0006] In this dehumidifier, the main fan is located on the air outlet side of the treatment area. The airflow direction in the first ventilation duct remains constant. The dehumidifying impeller is subjected to unilateral airflow for extended periods, leading to uneven aging of the impeller material. The performance degradation on the windward and leeward sides is inconsistent, resulting in uneven dehumidification capacity and decreased overall efficiency. The side that is constantly exposed to the wind is more prone to particulate matter accumulation, causing severe blockage on the windward side of the impeller. This requires the fan to provide greater power to maintain the same airflow, increasing energy consumption. Summary of the Invention
[0007] This invention provides a ventilation device with humidity regulation to solve the technical problems in the prior art where the dehumidifying impeller in the ventilation device is subjected to one-sided airflow for a long time, which causes the side of the impeller that is constantly exposed to the wind to become clogged, and the internal structure is subjected to uneven stress, uneven aging, and the service life is affected.
[0008] To solve the above problems, the present invention provides a ventilation device with humidity regulation, which adopts the following technical solution:
[0009] A ventilation device with humidity regulation includes a housing. Inside the housing are horizontally arranged impellers, dehumidification ventilation ducts, and regeneration ventilation ducts. The impeller includes a dehumidification zone and a regeneration zone. The dehumidification zone is located within the dehumidification ventilation duct, and the regeneration zone is located within the regeneration ventilation duct. The dehumidification ventilation duct includes:
[0010] Two dehumidification branch pipes are respectively installed on the upper and lower sides of the dehumidification area. The two dehumidification branch pipes cover the upper and lower sides of the dehumidification area and are connected to the dehumidification area. The dehumidification branch pipes are equipped with dehumidification air outlets that are directly opposite the upper and lower sides of the dehumidification area. A sealing plate is provided at the dehumidification air outlets to cover them. The sealing plate is installed on the dehumidification branch pipes with vertical movement.
[0011] A connecting pipe 1 is connected between the inlets of two dehumidification branch pipes. An air inlet 1 is provided on the right side wall of the connecting pipe 1. A switching structure 1 is provided inside the connecting pipe 1. The switching structure 1 includes a partition 1 and a baffle 1. Two baffles 1 are provided on each of the right inner side walls of the connecting pipe 1. The two baffles 1 are respectively located on the upper and lower sides of the air inlet 1. The left side wall of the connecting pipe 1 has an arc-shaped plate segment 1. The middle part of the partition 1 is rotatably mounted on the connecting pipe 1 around a rotating axis extending back and forth. The left end face of the partition 1 is arc-shaped and fits against the inner wall of the arc-shaped plate segment 1. The right end of the partition 1 is located between the two baffles 1. The partition 1 can be driven to rotate, thereby switching between the state in which the right end of the partition 1 abuts against the two baffles 1 respectively.
[0012] The partition is connected to the two sealing plates. When the partition swings to the point where the air inlet is connected to only one of the dehumidification branch pipes, the sealing plate on the other dehumidification branch pipe is moved by the partition, causing the dehumidification outlet to be exposed.
[0013] By adopting the above technical solution, since the airflow direction in the dehumidification zone of the existing rotor is generally different from that in the regeneration zone, but the area of the dehumidification zone is larger than that of the regeneration zone, the rotor is exposed to the wind direction of the dehumidification zone for a longer period of time. By setting a rotatable partition, when the partition rotates to the right end and contacts the two baffles, the air inlet is connected to only one of the dehumidification branch pipes, and the dehumidification outlet on the other side of the dehumidification branch pipe is opened. In this way, the airflow through the dehumidification zone of the rotor can be reversed. By regularly reversing the airflow through the rotor, the rotor can avoid internal deformation and uneven aging caused by long-term exposure to airflow from one side, which can improve the service life of the rotor. In addition, since the humidity is usually higher on the side of the dehumidification zone where the airflow enters, dust blockage is more likely to occur. By regularly switching the airflow direction, the blockage on both sides can be evenly distributed, thereby improving the ventilation effect of the rotor.
[0014] Furthermore, the regenerative ventilation ductwork includes:
[0015] Two regeneration branch pipes are respectively located on the upper and lower sides of the rotor. The two regeneration branch pipes cover the upper and lower sides of the regeneration area and are connected to the regeneration area. The regeneration branch pipes are equipped with regeneration air outlets that are directly opposite the upper and lower sides of the regeneration area. The regeneration air outlets are equipped with sealing plates that can cover them. The sealing plates are movably installed on the regeneration branch pipes.
[0016] Connecting pipe 2 is connected between the inlets of two regeneration branch pipes. Air inlet 2 is provided on the right side wall of connecting pipe 2. Switching structure 2 is provided inside connecting pipe 2 to connect air inlet 2 with different regeneration branch pipes.
[0017] By adopting the above technical solution, by setting a switching structure two in the regeneration ventilation duct, the airflow direction through the regeneration zone can be changed. Since the air flowing through the regeneration zone is hot air, regularly switching the airflow direction in the regeneration zone can make the overall heating of the rotor more uniform, thereby making the aging of both sides of the rotor more uniform and extending the service life of the rotor.
[0018] Furthermore, the switching structure 2 includes a partition 2 and a baffle 2. Two baffles 2 are provided on the right side wall of the connecting pipe 2. The two baffles 2 are respectively located on the upper and lower sides of the air inlet 2. There is an arc-shaped plate segment 2 on the left side wall of the connecting pipe 2. The middle part of the partition 2 is rotatably installed on the connecting pipe 2 around the rotating axis extending back and forth. The left end face of the partition 2 is arc-shaped and the inner wall of the arc-shaped plate segment 2 is in contact with it. The right end of the partition 2 is located between the two baffles 2. The partition 2 can be driven to rotate, thereby switching between the state of the right end abutting against the two baffles 2 respectively.
[0019] The partition plate 2 is connected to the two sealing plates 2 by a transmission. When the partition plate 2 swings to the point where the air inlet 2 is only connected to one of the regeneration branch pipes, the sealing plate 2 on the other regeneration branch pipe is moved along with it, causing the regeneration air outlet to be exposed.
[0020] Furthermore, partition one and partition two are connected by a transmission so that when partition one rotates, it can drive partition two to rotate in the opposite direction at the same speed as partition one.
[0021] By adopting the above technical solution, when the first partition rotates, it drives the second partition to rotate, thereby realizing the simultaneous reversal of the air flowing through the dehumidification zone and the regeneration zone. This saves power costs, simplifies the structure, and ensures that the air flow directions of the dehumidification zone and the regeneration zone are kept opposite, making the air pressure distribution on the rotor more uniform and the stress situation better.
[0022] Furthermore, the rotation axis of partition one and the rotation axis of partition two are arranged horizontally at intervals, and both partition one and partition two are connected with gears that prevent rotation on the same axis, and the two gears mesh with each other.
[0023] Using the above technical solution, the partition one and partition two rotate in opposite directions at the same speed through two meshing gears, resulting in a simple transmission structure.
[0024] Furthermore, a transmission assembly is provided between the baffle and the two sealing plates. The transmission assembly includes a movable push plate that is elastically slidably connected to the baffle. A limiting plate is provided above the movable push plate. An energy storage elastic element is connected to the top of the limiting plate. A trigger rod is provided on the side of the energy storage elastic element. A support plate is connected to the top of the energy storage elastic element. The support plate and the sealing plates are vertically fixed. A locking element that can elastically slide back and forth is provided on the inner wall of the connecting pipe. The locking element has a locking step for limiting the upward movement of the support plate. The locking element also has an unlocking ramp. When the movable push plate moves upward, it drives the trigger rod to move upward. The trigger rod pushes the locking element to move horizontally through the unlocking ramp, causing the locking step to be misaligned with the support plate, thereby releasing the energy storage elastic element. An auxiliary air outlet is provided on the front and rear side walls of the connecting pipe. The auxiliary air outlet and the air inlet are at the same horizontal height. A one-way valve is provided inside the auxiliary air outlet.
[0025] By adopting the above technical solution, and by setting the above transmission component one, during the state switching process of partition one, the two sealing plates one respectively block the two dehumidification air outlets, so that the air entering the dehumidification branch pipe will not be discharged. The dehumidification air outlet will only open when the state switching of partition one is completed, so as to avoid the air being discharged without being dehumidified and thus affecting the dehumidification efficiency.
[0026] Furthermore, the casing is also equipped with a regeneration fan and a heating module. Both the regeneration fan and the heating module are located in the regeneration ventilation duct and are located on the inlet side of the second air inlet. The outlet of the regeneration fan faces the heating module and is used to guide the outside air to the heating module. After being heated by the heating module, the air is sent to the second air inlet.
[0027] Furthermore, a dehumidifying fan is installed in the dehumidifying ventilation duct, and the dehumidifying fan is located on the outlet side of the dehumidifying air outlet.
[0028] Furthermore, the impeller includes a support frame and dehumidifying material. The support frame includes an inner sleeve and an outer sleeve arranged coaxially, as well as multiple connecting plates evenly arranged around the axis of the inner sleeve and the outer sleeve. A piece of dehumidifying material is provided between any two adjacent connecting plates.
[0029] The above technical solution employs a split design for the dehumidifying material, making it easy to replace parts of the dehumidifying material when they are damaged.
[0030] Furthermore, a cleaning mechanism is also provided inside the casing. The cleaning mechanism includes two water-retaining shells and two liquid-push plates. The two water-retaining shells are located on the upper and lower sides of the rotating wheel and can move up and down. The two water-retaining shells can move towards the rotating wheel and fit against the edge of the support frame on the outside of the single dehumidifying material. The two liquid-push plates slide up and down through the two water-retaining shells respectively. A cleaning chamber for containing cleaning liquid is formed between the two liquid-push plates. The two liquid-push plates can move up and down synchronously, driving the cleaning liquid in the cleaning chamber to flow up and down through the dehumidifying material.
[0031] Using the above technical solution, the rotor can be cleaned without disassembling it, making the cleaning operation more convenient. While cleaning is being carried out, the rotors in the dehumidification zone and the uncleaned regeneration zone can continue to work, resulting in higher efficiency.
[0032] The beneficial effects of the humidity-regulating ventilation device provided by this invention are as follows: This invention can periodically reverse the direction of air passing through the rotor, avoiding uneven aging, internal structural deformation, and shortened service life caused by the rotor being subjected to air pressure from one direction for a long time. This invention also allows for cleaning of the dehumidifying material without disassembling the rotor; the dehumidification zone can remain operational during the cleaning process, and the ventilation device does not need to be shut down for cleaning, resulting in higher efficiency.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0045] The following is one embodiment of a ventilation device with humidity regulation provided by the present invention:
[0046] like Figures 1-9 As shown, a ventilation device with humidity regulation includes a housing, a rotor, a dehumidification ventilation duct, and a regeneration ventilation duct.
[0047] like Figure 1 , Figure 2 As shown, the housing is used to fix the unit to an indoor wall where ventilation is required. The housing includes a main housing 1 and a base plate 2. The bottom of the main housing 1 has an opening, and the base plate 2 is sealed at the opening of the main housing 1 and fixedly connected to the main housing 1 by connecting bolts.
[0048] The main housing 1 is also provided with air inlet 101, air inlet 2 102, air outlet 103 and air outlet 2 104. Air inlet 101 and air inlet 2 102 are connected to the outside through pipes passing through the wall, air outlet 103 is connected to the inside, and air outlet 2 104 is connected to the outside through pipes passing through the wall.
[0049] A rotating shaft 14 is also provided inside the main housing 1. The rotating shaft 14 is rotatably mounted on the main housing 1 and is kept in a fixed position relative to the main housing 1 in the axial direction of the rotating shaft 14.
[0050] like Figure 3 As shown, the rotating wheel includes a support frame and a dehumidifying material 6. The support frame includes an outer sleeve 4, an inner sleeve 3, and multiple connecting plates 5 evenly arranged around the axis of the rotating wheel, which are connected between the outer sleeve 4 and the inner sleeve 3. The cross-section of the dehumidifying material 6 is fan-shaped, and a piece of dehumidifying material 6 is provided between each pair of adjacent connecting plates 5. A water inlet 7 is provided on the outer sleeve 4 corresponding to the area where each piece of dehumidifying material 6 is located.
[0051] The inner sleeve 3 is fitted onto the outside of the rotating shaft 14 to prevent rotation, and its position relative to the rotating shaft 14 is fixed in the axial direction of the rotating shaft 14. A drive motor is fixedly installed on the outside of the housing. The drive motor is connected to the rotating shaft 14 for driving the rotating shaft 14 to rotate, thereby driving the rotating wheel to rotate at a speed of one revolution every 40-50 minutes.
[0052] like Figure 4 , Figure 5 As shown, the dehumidification ventilation duct includes a dehumidification branch pipe, a connecting pipe 15, a dehumidification inlet pipe, and a dehumidification outlet pipe. There are two dehumidification branch pipes, which are symmetrically distributed on the upper and lower sides of the rotor.
[0053] The dehumidification branch pipe includes a dehumidification baffle 13 and a dehumidification straight pipe section 9. The dehumidification baffle 13 is a shell structure with a fan-shaped cross-section and an opening on the side facing the rotor. The outer diameter of the dehumidification baffle 13 is the same as the outer diameter of the outer sleeve 4, and the inner diameter of the dehumidification baffle 13 is the same as the inner diameter of the inner sleeve 3. The dehumidification baffle 13 covers a portion of the right side of the rotor, and the area of the rotor covered by the dehumidification baffle 13 is the dehumidification zone.
[0054] A fan-shaped dehumidification air outlet is provided on the horizontal side wall of the dehumidification baffle 13, such as... Figure 7 As shown, a sealing plate 34, which is adapted to the shape of the dehumidification outlet and wider than the dehumidification outlet, is provided on the side of the dehumidification baffle 13 facing away from the rotating wheel. Multiple vertically arranged guide rods 35 are connected to the side of the sealing plate 34 facing the rotating wheel. The guide rods 35 slide up and down through the dehumidification baffle 13. The bottom end of the guide rods 35 is connected to a connecting rod 30 extending to the left and right. The right end of the connecting rod 30 extends to the right end of the inner cavity of the dehumidification straight pipe section 9.
[0055] The inlet of the dehumidification straight pipe section 9 is located at the right end of the dehumidification straight pipe section 9, and is located on the side of the dehumidification straight pipe section 9 facing the rotor.
[0056] like Figure 7 , Figure 8 As shown, the connecting pipe 15 extends vertically and connects the inlets of the two dehumidification straight pipe sections 9. The right side wall of the connecting pipe 15 is provided with an air inlet 1, and the left side wall is provided with an arc-shaped plate section 151.
[0057] A switching structure is provided inside the connecting pipe 15. The switching structure includes a baffle 24 and a partition 20. There are two baffles 24, both connected to the inner side of the right side wall of the connecting pipe 15 and respectively located on the upper and lower sides of the air inlet. The partition 20 is located between the two baffles 24. A shaft segment 18 extending forward and backward is connected to the front and rear sides of the partition 20, respectively. The two shaft segments 18 are coaxial and rotatably pass through the front and rear walls of the connecting pipe 15, respectively.
[0058] The housing is equipped with a drive unit for rotating the partition 20. The drive unit is a motor and is connected to the shaft section 18 located at the rear. The drive unit is used to drive the partition 20 to rotate. The left end of the partition 20 is arc-shaped and fits against the inner wall of the arc-shaped plate section 151.
[0059] like Figure 6 As shown, on the right inner side wall of the connecting pipe 15, three sets of support plates are arranged at intervals on the upper and lower sides of the two baffles 24. Each set of support plates includes two support plates 27 arranged symmetrically in front and behind.
[0060] One end of the dehumidifying air inlet pipe is connected to the air inlet, and the other end is connected to the air inlet 101, which is used to guide outside air to the air inlet.
[0061] The dehumidification outlet duct includes a main dehumidification outlet duct and two branch dehumidification outlet ducts 8. One end of each branch dehumidification outlet duct 8 is connected to the inlet of the main dehumidification outlet duct, and the other end of each branch dehumidification outlet duct 8 is connected to the dehumidification outlet on each of the two dehumidification baffles 13. The outlet of the main dehumidification outlet duct is connected to the aforementioned air outlet 103, which is used to guide the dried air to the air outlet 103 for discharge.
[0062] A dehumidifying fan is installed on the main dehumidifying air outlet pipe. The dehumidifying fan is used to provide power for the air circulation in the dehumidifying pipe. The dehumidifying fan is a centrifugal fan. The main dehumidifying air outlet pipe and the dehumidifying fan are not shown in the figure.
[0063] like Figure 6 , Figure 7 , Figure 8 As shown, a set of transmission components is provided between the partition 20 and the two sealing plates 34, and the two sets of transmission components are arranged symmetrically.
[0064] The transmission assembly 1 includes a guide rod 22, a movable push plate 21, a reset elastic element 23, an energy storage elastic element 36, a trigger rod 26, and a locking element 1. The specific structure of the transmission assembly 1 located at the top will now be described.
[0065] Three guide rods 22 are spaced apart, extending vertically and sliding along the baffle 24. A movable push plate 21 is horizontally arranged and connected to the bottom of the three guide rods 22. The front and rear side walls of the movable push plate 21 are in contact with the front and rear inner side walls of the connecting pipe 15, and the right side wall of the movable push plate 21 is in contact with the right inner side wall of the connecting pipe 15. Three reset elastic elements 23 are provided, all connected between the movable push plate 21 and the baffle 24, and respectively sleeved on the outside of the three guide rods 22. When the reset elastic elements 23 are in the free state, the movable push plate 21 is flush with the top inner wall of the air inlet.
[0066] A horizontally arranged limiting plate 25 is connected to the top of the guide rod 22. The limiting plate 25 is located above the baffle 24. A vertically extending guide rod 37 is connected above the limiting plate 25. An energy-storing elastic element 36 is connected to the top of the limiting plate 25 and sleeved on the outside of the guide rod 37. A support plate 44 is connected to the top of the energy-storing elastic element 36. A vertically extending support tube 31 is connected to the top of the support plate 44. The top of the guide rod 37 passes through the support plate 44 and extends into the support tube 31. The guide rod 37 can slide up and down relative to the support plate 44 and the support tube 31. A mounting plate 29 is connected to the top of the three support tubes 31. The mounting plate 29 is connected to the right end of the connecting rod 30.
[0067] Each limiting plate 25 has two vertically extending trigger rods 26 connected to its top. The two trigger rods 26 are symmetrically arranged on the front and rear sides of the energy storage elastic element 36.
[0068] There are six locking components. Each of the two support plates 27 in each support plate group 1 is connected to a locking component 1. The locking components 1 are elastically slidably connected to the corresponding support plate 27 through the elastic telescopic rods 28 extending forward and backward. The two locking components 1 on each support plate group 1 are symmetrically distributed forward and backward.
[0069] The locking component includes a locking block 32 and an unlocking block 33. The locking block 32 is located above the unlocking block 33. The locking block 32 has a reset ramp 321. The two reset ramps 321 on the two locking blocks 32 are arranged facing each other and moving closer to each other from top to bottom. The bottom of the locking block 32 has a locking plane. The unlocking block 33 is connected to the locking plane. The unlocking block 33 has an unlocking ramp 331. The two unlocking ramps 331 on the two unlocking blocks 33 are arranged facing each other and moving further apart from top to bottom. The locking plane protrudes from the unlocking block 33 towards the other locking block 32, so that a locking step is formed on the locking block 32. The two locking steps are positioned above the support plate 44.
[0070] When the right end of partition 20 swings toward the upper baffle 24, it causes the movable push plate 21 to move upward, compressing the reset elastic element 23, moving the limiting plate 25 upward, compressing the energy storage elastic element 36, and causing the trigger rod 26 to move upward by the limiting plate 25. The trigger rod 26 contacts the unlocking ramp 331, pushing the two locking elements away from each other. When partition 20 rotates to the limit state where the reset elastic element 23 can no longer be compressed, the two locking elements move away from each other until they are horizontally offset from the support plate 44. The energy storage elastic element 36 releases and extends, thereby causing the support pipe 31 to move upward, and then causing the sealing plate 34 to move upward, exposing the dehumidification outlet. At this time, the air inlet is only connected to the lower dehumidification branch pipe, and the air flows upward through the rotor for dehumidification.
[0071] By driving the partition 20 to rotate in the opposite direction, the right end of the partition 20 is lowered to its limit, which can open the dehumidification outlet located below and make the air inlet connected only to the dehumidification branch pipe located above, so that the air flows from top to bottom through the rotor for dehumidification.
[0072] Due to the aforementioned transmission component 1, the energy storage elastic element 36 is only released when the partition 20 swings to its limit state. During the process of the partition 20 swinging and switching states but not yet swinging to its limit state, the air inlet 1 is first connected to one of the dehumidification branch pipes for a period of time before the dehumidification outlet on the other dehumidification branch pipe is opened.
[0073] like Figure 8 As shown, an auxiliary air outlet 152 is provided on the front side wall of the connecting pipe 15. The auxiliary air outlet 152 is located directly to the left of the rotation axis of the partition 20. A pneumatic one-way valve is provided inside the auxiliary air outlet 152. An auxiliary air outlet pipe 1 is connected to the auxiliary air outlet 152. The outlet end of the auxiliary air outlet pipe 1 extends to the outside of the casing and passes through the wall to the outside.
[0074] During the switching process of partition 20, before the dehumidification outlet is opened, the pressure in the dehumidification branch pipe increases, the pneumatic check valve is opened, and the incoming gas can be discharged through the auxiliary outlet pipe to maintain the pressure in the chamber. The dehumidification fan does not need to stop during the switching process.
[0075] The regenerative ventilation duct includes a regenerative branch pipe, a connecting pipe 16, a regenerative air inlet pipe, and a regenerative air outlet pipe. There are two regenerative branch pipes, which are symmetrically distributed on the upper and lower sides of the impeller.
[0076] like Figure 4 , Figure 5 As shown, the regeneration branch pipe includes a regeneration baffle 12 and a regeneration straight pipe section 11. The regeneration baffle 12 is a shell structure with a fan-shaped cross-section and an opening on the side facing the rotor. The outer diameter of the regeneration baffle 12 is the same as the outer diameter of the outer sleeve 4, and the inner diameter of the regeneration baffle 12 is the same as the inner diameter of the inner sleeve 3. The regeneration baffle 12 covers the area on the rotor that is not covered by the dehumidification baffle 13. The area in the rotor covered by the regeneration baffle 12 is the regeneration zone.
[0077] A fan-shaped regeneration air outlet is provided on the horizontal side wall of the regeneration baffle 12. On the side of the regeneration baffle 12 facing away from the rotating wheel, there is a sealing plate II that matches the shape of the regeneration air outlet and is wider than the regeneration air outlet. Multiple vertically arranged guide rods II are connected to the side of the sealing plate II facing the rotating wheel. The guide rods II slide vertically through the regeneration baffle 12. The bottom end of the guide rods II is connected to a connecting rod II extending horizontally. The right end of the connecting rod II extends to the right end of the inner cavity of the regeneration straight pipe section 11. The structure of the sealing plate II can be referenced from the sealing plate I 34, which is not shown in the figure.
[0078] The inlet of the regeneration straight pipe section 11 is located at the right end of the regeneration straight pipe section 11 and is located on the side of the regeneration straight pipe section 11 facing the rotor.
[0079] The second connecting pipe 16 extends vertically and connects the inlets of the two regeneration straight pipe sections 11. The right side wall of the second connecting pipe 16 is provided with an air inlet 2. The structure of the second connecting pipe 16 is the same as that of the first connecting pipe 15, and the first connecting pipe 15 mentioned above can be referred to.
[0080] A switching structure 2 is provided inside the connecting pipe 2 16. The switching structure 2 includes a baffle 2 and a partition 2. A shaft segment 2 19 extending forward and backward is connected to the front and rear sides of the partition 2, respectively. The two shaft segments 2 19 are coaxial and rotatably pass through the front and rear pipe walls of the connecting pipe 2 16, respectively. The structure of the switching structure 2 is the same as that of the switching structure 1, and can be referred to as the switching structure 1 described above, but is not shown in the figure.
[0081] One end of the regenerated air inlet pipe is connected to air inlet 2, and the other end is connected to air inlet 2 102, which is used to guide outside air to air inlet 2.
[0082] The regeneration air outlet duct includes a main regeneration air outlet duct and two branch regeneration air outlet ducts 10. One end of each branch regeneration air outlet duct 10 is connected to the regeneration air outlet on the regeneration baffle 12, and the other end is connected to the inlet of the main regeneration air outlet duct. The outlet of the main regeneration air outlet duct is connected to the aforementioned air outlet 104. The main regeneration air outlet duct is not shown in the figure.
[0083] The regeneration air inlet duct is equipped with a heating module and a regeneration fan. The regeneration fan provides power for airflow within the regeneration duct, drawing outdoor air into the duct and then exhausting it outdoors. The heating module, using an electric heating wire, is located between the second air inlet and the regeneration fan. The outlet of the regeneration fan faces the heating module, driving airflow towards it. After being heated by the heating module, the air enters the second air inlet to dry the regeneration area. The structure of the heating module and the regeneration fan is not shown in the figure.
[0084] A set of transmission components 2 is provided between the aforementioned partition 2 and the two sealing plates 2. The two sets of transmission components 2 are arranged symmetrically. The transmission component 2 includes a guide rod 2, a movable push plate 2, a reset elastic element 2, an energy storage elastic element 2, a trigger rod 2, and a locking element 2. The structure of the transmission component 2 is the same as that of the transmission component 1, and its specific structure will not be described in detail here.
[0085] The connecting pipe 16 is equipped with an auxiliary air outlet 2, which is connected to an auxiliary air outlet pipe 2. The outlet end of the auxiliary air outlet pipe 2 extends to the outside of the casing and passes through the wall to the outside. A pneumatic one-way valve is installed inside the auxiliary air outlet 2. When the upper and lower sealing plates 2 are not opened during the switching of the partition 2, the pressure inside the connecting pipe 16 increases, the pneumatic one-way valve is opened, and the gas that enters can be discharged through the auxiliary air outlet pipe 2.
[0086] like Figure 4 , Figure 5 , Figure 6 As shown, the shaft segment 18 located on the front side and the shaft segment 2 19 located on the rear side are arranged at intervals on the left and right sides and both of them are anti-rotation on the outer side. The two gears 17 mesh with each other so that when the partition 20 is driven to rotate, it can drive the partition 2 to rotate in the opposite direction at the same speed, thereby keeping the airflow direction of the regeneration zone and the dehumidification zone in opposite directions.
[0087] like Figure 9 As shown, the rotating wheel is also equipped with a cleaning mechanism, which includes a water-blocking shell 41 and a liquid-pushing plate 40. There are two water-blocking shells 41, which are symmetrically arranged on the upper and lower sides of the rotating wheel. The shape of the water-blocking shell 41 is consistent with the shape of the part of the support frame wrapped around the outside of the single dehumidifying material 6 in the rotating wheel. A sealing strip is attached to the side wall of the water-blocking shell 41 facing the rotating wheel.
[0088] Three support rods 43 are connected to the side of the water-blocking shell 41 facing away from the rotating wheel, and a conversion plate 42 is connected to the side of the support rods 43 facing away from the water-blocking shell 41.
[0089] Two water-blocking shells 41 are respectively arranged inside the two regeneration baffles 12 and are slidably mounted on the regeneration baffles 12. Two electric push rods are provided inside the housing. The two electric push rods are respectively connected to two conversion plates 42 and are used to drive the two water-blocking shells 41 to move towards each other, so that the water-blocking shells 41 are pressed against the upper and lower surfaces of the support frame in the wheel.
[0090] Two liquid-pushing plates 40 are provided. The two liquid-pushing plates 40 slide up and down through the two water-blocking shells 41 respectively. The circumferential edges of the liquid-pushing plates 40 are covered with sealing strips. The two water-blocking shells 41 and the two liquid-pushing plates 40 form a chamber for containing cleaning liquid.
[0091] A vertically extending movable rod 38 is provided on the outer side of the water-blocking outer shell 41. The movable rod 38 is slidably connected to the regeneration baffle 12. The two ends of the movable rod 38 are respectively connected to two liquid-pushing plates 40 through two L-shaped parts 39. The L-shaped parts 39 include a horizontal rod and a vertical rod. A lifting mechanism is provided inside the housing to drive the movable rod 38 to move up and down reciprocally. The lifting mechanism adopts an electric push rod. When the movable rod 38 moves up and down reciprocally, it can drive the two liquid-pushing plates 40 to move up and down reciprocally inside the water-blocking outer shell 41, causing the cleaning liquid in the cleaning chamber to move up and down reciprocally through the dehumidifying material 6, thereby cleaning the dehumidifying material 6. The dehumidifying material 6 is made of a washable material, such as a polymer-based composite adsorbent.
[0092] A water injection pipe is also connected to the main housing 1. The outlet of the water injection pipe is horizontally slidably mounted on the main housing 1. The main housing 1 is also equipped with a moving drive component, which is an electric push rod. The output end of the moving drive component is connected to the water injection pipe and is used to drive the outlet to insert into the water inlet 7 when the water inlet 7 on the rotating wheel rotates to be coaxial with the outlet. The water inlet 7 and the outlet adopt a self-sealing quick-connect plug design. The water inlet 7 is equipped with a spring-loaded valve core that is normally closed. When the outlet is inserted into the water inlet, it can push open the valve core and open the flow channel. When the outlet is pulled out, the spring pushes the valve core to reset, realizing automatic sealing. The sealing quick-connect plug structure is existing technology, and its structure will not be described in detail here.
[0093] The vertical rod located below is hollow inside and communicates with the space above the liquid pusher plate 40. The bottom of the vertical rod is connected to a drain pipe, which extends through the main housing 1 to the outside of the main housing 1. A valve is provided on the drain pipe. After cleaning, the valve can be opened to allow the liquid to be discharged from the drain pipe. The above-mentioned water injection pipe and drain pipe are not shown in the figure.
[0094] When in use, this invention operates as follows: when indoor humidity is high, the drive motor is controlled to drive the dehumidifying fan to rotate slowly and uniformly. The dehumidifying fan draws outside air into the dehumidifying pipe, and the air is dehumidified in the dehumidifying zone of the dehumidifying fan before being discharged into the room. The regeneration fan draws outside air into the regeneration pipe, and the outside air is heated by the heating module before being blown into the regeneration zone to dry the dehumidifying fan. The high-temperature air passes through the regeneration zone and is discharged to the outside. The dried dehumidifying fan continues to rotate slowly into the dehumidifying zone to dehumidify the air.
[0095] After the equipment has been used for a set period of time, the drive component is driven to swing the partition 20. The right end of the partition 20 swings from top to bottom, and the upper reset elastic element 23 gradually extends. When the right end of the partition 20 swings to the top of the air inlet, the sealing plate 34 returns to the dehumidification baffle 13 to block the upper dehumidification air outlet. At this time, both the upper and lower dehumidification air outlets are blocked. Then, the right end of the partition 20 swings from top to bottom from the top of the air inlet to the bottom of the air inlet. The spaces on the upper and lower sides of the air inlet and the partition 20 are connected, while the upper and lower dehumidification air outlets are closed. The gas entering the connecting pipe 15 is discharged through the auxiliary air outlet 152, so that the air pressure in the dehumidification zone remains stable.
[0096] As partition 20 swings downwards until it contacts and pushes the lower movable push plate 21 downwards, the air inlet is only connected to the upper dehumidification branch pipe, completing the airflow direction switch. The auxiliary air outlet 152 is located below partition 20, and the upper and lower dehumidification air outlets are still blocked. At this time, the air entering the upper dehumidification branch pipe backflushes the rotor, which can flush away some of the dust and impurities stuck in the rotor. The blown-out dust and impurities are discharged through the auxiliary air outlet 152 and discharged outdoors to avoid affecting the indoor environment. When the lower reset elastic element 23 is compressed to its limit, the energy storage elastic element 36 is released, the lower dehumidification air outlet opens, and the air in the dehumidification area begins to pass through the rotor from top to bottom. After being dehumidified by the rotor, it is discharged into the room.
[0097] While partition 1 20 is switching, partition 2 is switched to the opposite position to partition 1 20 under the drive of the meshing gear 17. After the rotor in the regeneration zone is backflushed and dusted by air, the airflow direction is switched to a state of flowing from bottom to top.
[0098] After maintaining the above airflow direction in the dehumidification and regeneration zones for a period of time, the control drive drives the partition 20 to flip again, thereby switching the airflow direction in the dehumidification and regeneration zones once more. This cycle repeats, continuously switching the airflow direction in the dehumidification and regeneration zones, making the force on both sides of the rotor more even, resulting in more even aging and extending the rotor's service life.
[0099] After the aforementioned impeller has been working for a considerable period of time, a large amount of dust may accumulate inside, requiring cleaning. At this time, the equipment switches to cleaning mode. When the impeller rotates to the point where one of the dehumidifying materials 6 is vertically aligned with the water-blocking housing 41, the drive motor stops, causing the two water-blocking housings 41 to move closer together and press against the upper and lower surfaces of the support frame. This causes the water outlet of the water injection pipe to be inserted into the water inlet 7, filling the cleaning chamber with cleaning water. Then, the movable rod 38 is driven to move up and down reciprocally, causing the cleaning water to flow up and down through the dehumidifying material 6 to clean it. The above steps are repeated to clean the remaining dehumidifying materials 6 in sequence. While cleaning one dehumidifying material 6, the remaining dehumidifying materials 6 located in the dehumidification zone can be dehumidified, and the dehumidifying materials 6 in the regeneration zone can be regenerated. The cleaning process hardly affects the normal operation of the impeller.
[0100] The cleaning frequency is once or twice a year. Clean water is used as the cleaning agent. The liquid in the cleaning chamber should not be soaked outside the dehumidifying material 6 for a long time. Therefore, during cleaning, the liquid in the cleaning chamber should be quickly circulated up and down several times before being discharged. The hot air blown into the regeneration zone can dry the cleaned dehumidifying material 6 and the inner wall of the water-blocking outer shell 41 that is wet. The small amount of water that leaks into the regeneration baffle 12 during the water injection process can also be dried by the hot air.
