Description

Technical Field

[0001] The present invention belongs to the technical field of dehumidifiers, and specifically relates to a dehumidifier device with a multi-functional dual-filter chamber and alternating operation. Background Art

[0002] In some workplaces that require a dry environment, a multi-functional dehumidifier device is usually installed to dry the internal environment.

[0003] For example, a maintenance-free dehumidifier disclosed in a patent for invention with the authorization announcement number CN118698297A in the technical field of dehumidifiers includes a dehumidifier, which comprises a protective cover, an air duct arranged at the center inside the protective cover, a condensation cover arranged inside the protective cover, a dehumidification tank arranged between the air duct and the condensation cover, an air inlet pipe arranged at the top of the condensation cover, and a heating plate arranged inside the dehumidification tank; the air duct is provided with an air inlet channel penetrating through its side wall; a humidity sensor and a temperature sensor are installed inside the dehumidification tank.

[0004] Combined with the above cases and the actual situation, we found the following problems: Generally, a dehumidifier absorbs and dries moisture by setting a moisture-absorbing material in the internal air channel, such as a solid desiccant or a rotary dehumidifier. After the dehumidifier absorbs moisture, it needs to replace the desiccant and stop the machine to dry the desiccant. This not only wastes time, but also during the shutdown process, it cannot achieve the moisture absorption effect and affects the moisture absorption efficiency; or, like a rotary dehumidifier, it needs to continuously heat the regeneration area by setting a heating device while ventilating to dry the moisture-absorbing material to achieve the effect of non-stop drying. This consumes a large amount of energy, and when heating, the temperature is relatively high, which easily accelerates the aging of internal parts and increases the maintenance frequency. Summary of the Invention

[0005] The purpose of the present invention is to provide a dehumidifier device with a multi-functional dual-filter chamber and alternating operation to solve the above problems of the prior art.

[0006] To achieve the above purpose, the present invention provides a dehumidifier device with a multi-functional dual-filter chamber and alternating operation, which includes a housing. Inside the housing, there is a dehumidification component for alternating moisture absorption operation. The dehumidification component includes an air inlet structure for the flow of internal and external air, a main pipe structure for drying the wet air, a plurality of air outlet pipes regularly arranged on the main pipe structure, two adjustment structures for controlling the opening and closing of the air outlet pipes, and a plurality of butterfly valve structures for controlling the air flow inside the main pipe structure;

[0007] The main pipe structure is composed of two horizontal pipes, one on the top and the other on the bottom, and two vertical moisture absorption pipes arranged on the left and right;

[0008] The air inlet structure includes two air inlet pipes, one above the other, a fan disposed in the upper air inlet pipe, and a fan blade disposed in the lower air inlet pipe. The bottom end of the upper air inlet pipe communicates with the middle part of the upper horizontal pipe, and the top end of the lower air inlet pipe communicates with the middle part of the lower horizontal pipe.

[0009] The butterfly valve structure includes a valve plate and a shaft rod vertically disposed in the middle of the valve plate.

[0010] The adjustment structure includes a vertically disposed movable column, a transmission rod disposed in the movable column, and two piston mechanisms symmetrically disposed above and below on the outer side wall of the movable column.

[0011] In the technical solution of the present invention, the main pipe structure is integrally arranged in a shape of a rectangle with a hollow center, and a silica gel moisture absorption material for drying air and reusable is embedded in the inner wall of the moisture absorption pipe.

[0012] In the technical solution of the present invention, the upper air outlet pipes are disposed on both sides of the upper air inlet pipe, and the lower air outlet pipes are disposed on both sides of the lower air inlet pipe. The upper air outlet pipes and the upper air inlet pipes both pass through the top surface of the housing and communicate with the humid external environment, and the lower air outlet pipes and the lower air inlet pipes both pass through the bottom surface of the housing and communicate with the dry internal environment.

[0013] In the technical solution of the present invention, a linkage shaft is coaxially and fixedly connected below the rotating shaft of the fan. The bottom end of the linkage shaft sequentially passes through the upper horizontal pipe and the lower horizontal pipe and is coaxially fixed with the fan blade. The blade inclination angles of the fan and the fan blade are opposite.

[0014] In the technical solution of the present invention, a grille for blocking external sundries and dust is fixed at the pipe orifice of the air inlet pipe. Brush plates are fixed at both the upper and lower ends of the linkage shaft, and the brush plates are attached to the outer surface of the corresponding grille.

[0015] In the technical solution of the present invention, the butterfly valve structure is disposed at the position between the air inlet pipe and the air outlet pipe. A fixing block for fixing the butterfly valve structure is provided at the position on the outer wall of the air inlet pipe corresponding to the shaft rod.

[0016] In the technical solution of the present invention, the two adjustment structures are disposed inside the rectangle with a hollow center of the main pipe structure. The two adjustment structures are centrosymmetrically arranged. A limiting rod is fixed near the middle on the outer side of the movable column. An outer extension is provided on the outer wall of the moisture absorption pipe corresponding to the limiting rod, and a limiting groove adapted to the outer end of the limiting rod is provided inside the outer extension.

[0017] It should be noted that in the translation of , there is an error in the original text description. It should be "The main pipe structure is integrally arranged in a shape of a rectangle with a hollow center" instead of "The main pipe structure is integrally arranged in a shape of a rectangle with a hollow center, and a silica gel moisture absorption material for drying air and reusable is embedded in the inner wall of the moisture absorption pipe." This is a more reasonable structure description. The above translation is based on the corrected content. If you have any other questions, please feel free to let me know.In the technical solution of the present invention, the top end of the transmission rod passes through the top surface of the movable column and is coaxially rotatably connected to the corresponding shaft rod above. Symmetrically fixed on the side wall of the transmission rod near the bottom end are outwardly extending clamping balls, and a spiral groove adapted to the clamping balls is provided on the inner wall of the movable column.

[0018] In the technical solution of the present invention, the piston mechanism consists of an L-shaped connecting rod and a piston fixed at the end of the vertical section of the connecting rod. The vertical section of the connecting rod passes through the pipe wall of the corresponding horizontal pipe and extends into its interior. The end of the horizontal section of the connecting rod is fixed to the outer wall of the corresponding movable column. The positions of several pistons correspond one by one to the positions of several air outlet pipes.

[0019] In the technical solution of the present invention, a humidity detector for detecting air humidity is fixed at the nozzle of the lower air outlet pipe, and the humidity detector is signal-connected to the driver of the butterfly valve structure on the corresponding side.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, by setting the dehumidification component, during use, when the humidity detector detects that the humidity at the nozzle of the air outlet pipe in the left lower part of the air outlet environment is too high, it will control the butterfly valve structure in the upper left to close and the butterfly valve structure in the lower left to open. The shaft rod of the butterfly valve structure in the upper left drives the transmission rod on the same side to rotate. Through the cooperation of the clamping ball and the spiral groove, the movable column on this side is driven to move downward. At this time, the piston on this side moves downward synchronously, so that the air outlet pipe above this side is opened and the air outlet pipe below is closed. The dry air in the internal environment is inhaled into the moisture absorption pipe on the left from the lower air inlet pipe. The air flow direction on the right is opposite to that on the left, and the humid air in the external environment is inhaled into the moisture absorption pipe on the right, thereby realizing the alternating operation of the moisture absorption pipes, reducing the time wasted in replacing the moisture absorption material or heating and re-drying the moisture absorption material, and improving the moisture absorption efficiency and effect.

[0022] 2. In the present invention, by setting the air inlet structure and the piston mechanism, during moisture absorption, a linkage shaft is coaxially and fixedly connected below the rotating shaft of the fan. The bottom end of the linkage shaft passes through the upper horizontal pipe and the lower horizontal pipe in sequence and is coaxially fixed to the fan blade. The inclination angle of the blades of the fan is opposite to the inclination angle of the blades of the fan blade. Since the device abandons the use of a heating device to heat the dry air in order to reduce energy consumption, by setting the linkage shaft, the fan and the fan blade rotate synchronously. The fan blade always inhales dry air to dry the moisture absorption material that has been completely saturated with water. The drying time matches the time for the moisture absorption material in the other moisture absorption pipe to be completely saturated with water. The drying time is relatively long, effectively reducing the influence of the lack of a heating device, reducing energy consumption, and making the use safer. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0036] Unless otherwise clearly stated, throughout the specification, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0037] Referring to Figures 1 - 9 shown, this embodiment provides a technical solution:

[0038] In the moisture absorber device with multifunctional dual-filter chamber alternating operation of the present invention, it includes a housing 1. Inside the housing 1, there is a dehumidification component 2 for alternating moisture absorption operation. The dehumidification component 2 includes an air inlet structure 21 for the flow of internal and external air, a main pipe structure 22 for drying the wet air, a number of air outlet pipes 23 regularly arranged on the main pipe structure 22, two adjustment structures 24 for controlling the opening and closing of the air outlet pipes 23, and a number of butterfly valve structures 25 for controlling the air flow inside the main pipe structure 22;

[0039] The main pipe structure 22 is composed of two upper and lower horizontal pipes 221 and two left and right vertically arranged moisture absorption pipes 222. The moist air is dried through the filter chambers formed by moisture absorption materials inside the two moisture absorption pipes 222. The design of the two moisture absorption pipes 222 ensures that after the moisture absorption materials in the moisture absorber are fully saturated with water, there is no need to stop the machine to replace the moisture absorption materials or heat and redry the moisture absorption materials, which can not only improve the working efficiency but also reduce the energy consumption;

[0040] The air inlet structure 21 includes two upper and lower air inlet pipes 211, a fan 212 arranged inside the upper air inlet pipe 211, and a fan blade 216 arranged inside the lower air inlet pipe 211. The bottom end of the upper air inlet pipe 211 is communicated with the middle part of the upper horizontal pipe 221, and the top end of the lower air inlet pipe 211 is communicated with the middle part of the lower horizontal pipe 221. When the fan 212 is started, the upper air inlet pipe 211 sucks the relatively moist air in the external environment into the moisture absorption pipe 222 for drying. The fan blade 216 rotates synchronously with the fan 212, and reintroduces the dry air in the internal environment into the other moisture absorption pipe 222 to dry the moisture absorption materials that have been fully saturated with water in this moisture absorption pipe 222. Through this design, not only the moisture absorption materials are dried without stopping the machine, but also the air flow in the internal environment is accelerated;

[0041] The butterfly valve structure 25 includes a valve plate 251 and a shaft rod 252 vertically arranged in the middle of the valve plate 251. The butterfly valve structure 25 is set to control the air flow inside the moisture absorber. It should be noted that the butterfly valve structure 25 used in this device is an electronically controlled one;

[0042] The adjustment structure 24 includes a vertically arranged movable column 241, a transmission rod 242 arranged inside the movable column 241, and two piston mechanisms 243 symmetrically arranged up and down on the outer side wall of the movable column 241. By setting the movable column 241, while the butterfly valve structure 25 changes the air flow, the opening and closing of the air outlet pipe 23 are synchronously controlled to ensure that when the moisture absorption materials are dried, the dry air takes the water vapor out of the device.

[0043] In addition, as Figures 1 - 3As shown, the main pipe structure 22 is integrally arranged in a zigzag shape. A silica gel moisture-absorbing material for drying air is embedded in the inner wall of the moisture-absorbing pipe 222. The silica gel moisture-absorbing material can be reused after absorbing and drying water, and has a long service life, so as to reduce the replacement frequency of the moisture-absorbing material.

[0044] Specifically, the upper air outlet pipe 23 is arranged on both sides of the upper air inlet pipe 211, and the lower air outlet pipe 23 is arranged on both sides of the lower air inlet pipe 211. Both the upper air outlet pipe 23 and the upper air inlet pipe 211 pass through the top surface of the housing 1 to communicate with the humid external environment, and both the lower air outlet pipe 23 and the lower air inlet pipe 211 pass through the bottom surface of the housing 1 to communicate with the dry internal environment. The air outlet pipes 23 are all arranged in an L shape, and the horizontal section of the air outlet pipe 23 faces away from the air inlet pipe 211 side, so as to prevent more humid air directly discharged from the upper air outlet pipe 23 from being directly sucked in when the upper air inlet pipe 211 sucks air, which affects the moisture absorption efficiency, and at the same time prevent the dry air discharged from the lower air outlet pipe 23 from being directly sucked in by the lower air inlet pipe 211, resulting in the inability of the internal environment air to circulate.

[0045] In addition, as Figure 9 shown, a linkage shaft 213 is coaxially and fixedly connected below the rotating shaft of the fan 212. The bottom end of the linkage shaft 213 sequentially passes through the upper horizontal pipe 221 and the lower horizontal pipe 221 and is coaxially fixed with the fan blade 216. The blade inclination angles of the fan 212 and the fan blade 216 are opposite. Since the device abandons using a heating device to heat the dry air in order to reduce energy consumption, by setting the linkage shaft 213, the fan 212 and the fan blade 216 rotate synchronously, and the fan blade 216 always sucks in dry air to dry the moisture-absorbing material that has been completely water-absorbed. The drying time matches the time for the moisture-absorbing material in another moisture-absorbing pipe 222 to be completely water-absorbed. The drying time is longer, effectively reducing the influence of the lack of a heating device.

[0046] Furthermore, a grille net 214 for blocking external sundries and dust is fixed at the pipe orifice of the air inlet pipe 211. Brush plates 215 are fixed at both the upper and lower ends of the linkage shaft 213. The brush plates 215 are attached to the outer surface of the corresponding grille net 214. By setting the brush plates 215, the grille net 214 is cleaned.

[0047] In addition, as Figure 4As shown, the butterfly valve structure 25 is disposed at the position between the air inlet pipe 211 and the air outlet pipe 23. A fixing block 253 for fixing the butterfly valve structure 25 is provided at the position corresponding to the outer wall of the air inlet pipe 211 and the corresponding shaft rod 252. It should be noted that the opening and closing states of the valve plates 251 in the left and right butterfly valve structures 25 are opposite, and the opening and closing states of the valve plates 251 in the same-side butterfly valve structures 25 are also opposite, so as to ensure that only a single moisture absorption tube 222 absorbs moisture during the moisture absorption of the entire moisture absorption device, enabling the two moisture absorption tubes 222 to alternately perform moisture absorption operations, thereby reducing the time wasted in replacing or drying the moisture absorption material and improving the drying efficiency and effect.

[0048] In addition, as Figures 5 - 8 shown, two adjustment structures 24 are disposed inside the main pipe structure 22 in a zigzag shape. The two adjustment structures 24 are symmetrically arranged about the center to ensure that the two adjustment structures 24 are in different states and are adapted to the opening and closing states of the butterfly valve structures 25 on the same side. A limiting rod 244 is fixed at the middle part of the outer side of the movable column 241. A vertical extension 223 is provided at the position corresponding to the limiting rod 244 on the outer wall of the moisture absorption tube 222. A limiting groove 224 adapted to the outer end of the limiting rod 244 is provided inside the extension 223. By providing the limiting rod 244 and the limiting groove 224, the rotation of the movable column 241 can be restricted. At the same time, the limiting rod 244 can prevent the deflection force generated when the transmission rod 242 drives the movable column 241 to move downward from being transmitted to the piston mechanism 243, avoiding deformation of the piston mechanism 243 after long-term use and reducing the sealing performance, so that the entire device cannot work properly.

[0049] Furthermore, the top end of the transmission rod 242 passes through the top surface of the movable column 241 and is coaxially rotatably connected to the corresponding shaft rod 252 above. Symmetrically fixed to the side wall of the transmission rod 242 near the bottom are outwardly extending clamping balls 2422. A spiral groove 2411 adapted to the clamping balls 2422 is provided on the inner wall of the movable column 241. When the moisture absorption material on the left side has been completely saturated with water, the valve plate 251 in the butterfly valve structure 25 on that side will rotate and close, driving the transmission rod 242 to rotate. Through the cooperation of the clamping balls 2422 and the spiral groove 2411, the movable column 241 on that side is driven to move downward, and the valve plate 251 on the other side opens, causing the movable column 241 on the other side to move upward.

[0050] In addition, the piston mechanism 243 includes an L-shaped connecting rod 2431 and a piston 2432 fixed to the end of the vertical section of the connecting rod 2431. The vertical section of the connecting rod 2431 passes through the wall of the corresponding horizontal pipe 221 and extends into its interior. The end of the horizontal section of the connecting rod 2431 is fixed to the outer wall of the corresponding movable column 241. The positions of several pistons 2432 correspond one by one to the positions of several air outlet pipes 23. When the left movable column 241 that has completely absorbed water moves downward, the connecting rod 2431 on that side will drive the piston 2432 on the same side to move downward. At this time, the air outlet pipe 23 above on that side opens and the air outlet pipe 23 below on that side closes. The piston 2432 on the right side moves upward, driving the upper air outlet pipe 23 on the same side to close and the lower air outlet pipe 23 on the same side to open. At this time, the inhaled moist air can only enter from the moisture absorption pipe 222 of the dry moisture absorption material on the left side and be discharged from the lower air outlet pipe 23 on the right side. The rotation of the lower fan blade 216 drives the dry air in the internal environment to enter from the lower air inlet pipe 211 on the left side to dry the moisture absorption material and be discharged to the external environment from the upper air outlet pipe 23 on the left side.

[0051] In addition, it should be noted that a humidity detector for detecting air humidity is fixed at the nozzle of the lower air outlet pipe 23. The humidity detector is signal-connected to the driver of the butterfly valve structure 25 on the corresponding side. The driver of the butterfly valve structure 25 is fixed on the fixed block 253. The humidity of the air outlet environment is detected by the humidity detector to judge whether the moisture absorption material on that side has completely absorbed water. The driver of the butterfly valve structure 25 is controlled by the humidity detector. This is a commonly used technical means in the art and will not be elaborated here.

[0052] The working principle of the moisture absorber device with multi-functional double-filter cavity alternating operation in the present invention is specifically as follows:

[0053] During use, the fan 212 is started. At this time, the butterfly valve structure 25 above on the left side opens and the butterfly valve structure 25 below on the left side closes. The adjustment structure 24 on the left side is located on the upper side. The air outlet pipe 23 above on the left side closes and the air outlet pipe 23 below on the left side opens. At this time, the fan 212 inhales the relatively moist air in the external environment into the moisture absorption pipe 222 on the left side for drying, and the dried air is discharged from the air outlet pipe 23 below on the left side.

[0054] When the humidity detector detects that the humidity at the nozzle of the air outlet pipe 23 under the left side of the air outlet environment is too high, it will control the butterfly valve structure 25 above the left side to close and the butterfly valve structure 25 below the left side to open. At the same time, the shaft rod 252 of the butterfly valve structure 25 above the left side will drive the transmission rod 242 on the same side to rotate, and drive the movable column 241 on that side to move downward through the cooperation of the clamping ball 2422 and the spiral groove 2411. At this time, the piston 2432 on that side will move downward synchronously, so that the air outlet pipe 23 above that side is opened and the air outlet pipe 23 below is closed. The fan blade 216 rotates synchronously with the fan 212. At this time, the dry air in the internal environment is sucked into the moisture absorption pipe 222 on the left side from the air inlet pipe 211 below, and the moisture absorption material that has been completely water-absorbed in the moisture absorption pipe 222 is dried. The air flow direction on the right side is opposite to that on the left side.

[0055] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and obviously, many modifications and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the invention and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present invention, as well as various different selections and modifications. The scope of the present invention is intended to be defined by the specification and its equivalents.
