Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification, in particular to an air inlet processing component and a dehumidifier. Background Art

[0002] Rotary dehumidifier is an important branch of the air-conditioning field and a typical representative of temperature control and dehumidification.

[0003] The traditional rotary dehumidifier adopts a sheet metal structure, and the upper and lower side air ducts of the rotor are not designed reasonably, resulting in a decrease in the effective utilization rate of the actual rotor. Due to the compact internal structure of the dehumidifier, the size of the lower sheet metal air duct is limited, and the air outlet of the processing fan can only pass through a part of it, resulting in a large area of ​​dead corners. No processed air passes through this area, affecting the final dehumidification effect. In addition, there is an optimal headwind speed for rotary dehumidification. When selecting the rotor size, dehumidifier manufacturers will choose according to the optimal headwind speed range. However, due to the poor size of the air duct structure, the actual useful rotor area becomes smaller, and the local headwind speed becomes larger, exceeding the reasonable range, resulting in a poor dehumidification effect.

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0044] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0045] Reference Figure 1 and Figure 2The utility model provides an air inlet treatment member, which is used to be arranged on the air inlet side of the treatment zone and the air outlet side of the regeneration zone of the dehumidification rotor 2, and includes a first cavity 3 and a second cavity 4. It should be noted that the air inlet treatment member is preferably an integrally molded plastic member, and further, the plastic member is preferably a plastic material with high strength and good temperature resistance, which can improve the durability and life of the air inlet treatment member.

[0046] The air inlet processing member is an irregular structure as a whole, and the first cavity 3 is also designed as an irregular structure. A through hole penetrating both sides is arranged in the middle of the air inlet processing member for the support shaft of the dehumidification wheel 2 to pass through. The radial cross-section of the first cavity 3 gradually increases along the flow direction of the gas to be dehumidified. The first cavity 3 is used to be arranged at the air inlet side of the processing area of ​​the dehumidification wheel 2 and for the gas to be dehumidified to flow to the entire processing area of ​​the dehumidification wheel 2; specifically, the structure of the first cavity 3 is not a regular hollow truncated cone structure, but is similar to a hollow truncated cone with a small top surface inclined toward one side of the central axis, and the cavity wall of the first cavity 3 is preferably arranged in a special-shaped variable diameter manner. More specifically, the first cavity 3 formed by the special-shaped variable diameter arrangement can gradually increase the radial cross-section of the first cavity 3, and the cavity wall of the first cavity 3 undergoes a natural transition, without a dead angle area inside, so that the flow field of the gas to be dehumidified entering the cavity can become more uniform, and the entire surface area of ​​the processing area of ​​the dehumidification wheel 2 can be effectively utilized to avoid airflow accumulation and concentration on the surface of part of the processing area, thereby improving the dehumidification efficiency of the dehumidification wheel 2.

[0047] The second cavity 4 is isolated from the first cavity 3 , and the second cavity 4 is used to be arranged at the air outlet side of the regeneration zone of the dehumidification wheel 2 and discharge the regenerated gas.

[0048] As an example:

[0049] The first cavity 3 and the second cavity 4 cooperate with the end face of the dehumidification wheel 2 to form a circular covering surface, and the other end face of the first cavity 3 is configured as a circular interface for external pipes, etc., and the above-mentioned circular covering surface can cover the end face of the dehumidification wheel 2; for example, the treatment zone area of ​​the dehumidification wheel 2 is three quarters of the end face, and the regeneration zone area is one quarter of the end face, thereby constituting a complete end face of the dehumidification wheel 2, and adaptively, the first cavity 3 is configured to be a three quarters circular covering surface corresponding to the treatment zone area, and the second cavity 4 is configured to be a one quarter circular covering surface corresponding to the regeneration zone area.

[0050] It should be noted that a special-shaped variable diameter method is adopted in the first cavity 3 which has a circular interface at one end and a three-quarter area end face at the other end, so that the radial cross-section of the first cavity 3 is gradually increased, so that the flow field of the gas to be dehumidified entering the cavity becomes more uniform, and the entire surface area of ​​the treatment zone of the dehumidification wheel 2 can be effectively utilized, so as to avoid the accumulation of airflow on the surface of part of the treatment zone, thereby improving the dehumidification efficiency of the dehumidification wheel 2.

[0051] Therefore, the air inlet processing component is made of an integrally molded plastic structure with high strength and good temperature resistance, and the cavity wall of the first cavity 3 of the air inlet processing component adopts a special structure of special-shaped variable diameter, so that its radial cross-section gradually increases, so that the flow field discharged through the air duct of the first cavity 3 becomes more uniform, and the air flow is prompted to reach the entire processing area of ​​the dehumidification wheel 2, so that the wheel surface of the entire dehumidification area becomes an effectively utilized area, eliminating the dead corner area of ​​the processing area, and improving the dehumidification efficiency of the dehumidification wheel 2.

[0052] Reference Figures 3 to 8 The utility model also provides a dehumidifier, including: a dehumidification wheel 2 and an air inlet processing component.

[0053] The dehumidification wheel 2 includes a treatment zone and a regeneration zone, and the area ratio of the treatment zone to the regeneration zone can be 3:1, that is, the treatment zone is three-quarters of the fan-shaped area, and the regeneration zone is one-quarter of the fan-shaped area. In other embodiments, the area ratio of the treatment zone to the regeneration zone can also be other ratios, which are not limited here. The air inlet side of the treatment zone and the air outlet side of the regeneration zone are on the same side of the dehumidification wheel 2, and the air outlet side of the treatment zone and the air inlet side of the regeneration zone are on the same side of the dehumidification wheel 2, so that the flow direction of the gas to be dehumidified in the dehumidification wheel 2 is opposite to the flow direction of the regeneration gas.

[0054] The air inlet treatment member is the above-mentioned air inlet treatment member. When the air inlet treatment member is installed on the above-mentioned dehumidification wheel 2, the first cavity 3 can be located at the air inlet side of the treatment zone of the dehumidification wheel 2, and the second cavity 4 can be located at the air outlet side of the regeneration zone of the dehumidification wheel 2.

[0055] In a preferred embodiment, the dehumidifier further comprises: a chassis 1 and an air outlet treatment member. The air inlet treatment member is preferably an integrally formed plastic member, and further, the plastic member is preferably a plastic material with high strength and good temperature resistance, which can improve the durability and life of the air inlet treatment member.

[0056] The dehumidification wheel 2 is installed inside the chassis 1 .

[0057] The processing air outlet component is arranged on the air outlet side of the processing zone and the air inlet side of the regeneration zone of the dehumidification wheel 2, and the processing air outlet component includes a third cavity 5 and a side port 8; specifically, the third cavity 5 is used to be arranged at the air outlet side of the processing zone of the dehumidification wheel 2 and discharge the processed gas; the side port 8 is isolated from the third cavity 5, and the side port 8 is used to be arranged on the air inlet side of the regeneration zone of the dehumidification wheel 2.

[0058] It should be noted that the air outlet processing member is preferably an integrally formed plastic member, which avoids the complexity of a sheet metal structure and makes installation and sealing faster and more convenient.

[0059] As an example:

[0060] One end face of the air outlet processing component can be set to a circular covering surface that can cover the end face of the dehumidification wheel 2. The area of ​​one end of the third cavity 5 is three quarters of the circular covering surface, and the area of ​​the side port 8 is one quarter of the circular covering surface. Therefore, when the air outlet processing component is installed on the end face of the dehumidification wheel 2, the third cavity 5 can cover the air outlet side of the treatment area of ​​the dehumidification wheel 2, and the side port 8 can cover the air inlet side of the regeneration area of ​​the dehumidification wheel 2.

[0061] In a preferred embodiment, the dehumidifier further comprises at least two supporting members 6 detachably disposed inside the chassis 1 , and the dehumidification wheel 2 is rotatably disposed between two adjacent supporting members 6 .

[0062] It should be noted that a circular track or guide rail for the rotation of the dehumidification wheel 2 is arranged between the relative surfaces of two adjacent support members 6. The support member 6 is preferably a plate-like structure, and the inner side of the circular track of the support member 6 with a plate-like structure is a through opening structure, so that the treatment area and regeneration area of ​​the dehumidification wheel 2 can smoothly pass the corresponding regeneration gas or gas to be dehumidified.

[0063] Furthermore, a driving component 7, a transmission belt, a tensioner 9 and a limit switch 10 can be installed on the support member 6. The transmission belt is arranged on the dehumidification wheel 2. The driving component 7 transmits and connects the transmission belt and is used to drive the dehumidification wheel 2 to rotate. The tensioner 9 is used to tension the transmission belt. The limit switch 10 is used to be triggered when the dehumidification wheel 2 rotates to determine whether the dehumidification wheel 2 rotates.

[0064] It should be noted that the driving component 7 is preferably a transmission motor, and a pulley for connecting a transmission belt is installed at the output end of the transmission motor. The transmission belt is wound around the dehumidification wheel 2, the tensioner 9, the pulley and the limit switch 10. The transmission motor can drive the dehumidification wheel 2 to rotate through the transmission belt. When the dehumidification wheel 2 rotates one circle, the limit switch 10 is triggered once. There is a time setting in the program setting of the dehumidifier system. If the limit switch 10 exceeds the time setting range and does not trigger the program, it will be judged that the dehumidification wheel 2 has a rotation failure or does not rotate, so as to realize the monitoring of the working process of the dehumidification wheel 2.

[0065] In a preferred embodiment, it also includes a processing air duct component and a regeneration air duct component.

[0066] The processing air duct assembly includes a processing air inlet 11, a processing fan 12 and a processing air outlet 13. The gas to be dehumidified flows through the processing air inlet 11, the processing fan 12, the first cavity 3 of the processing air inlet member, the processing area of ​​the dehumidification wheel 2, the third cavity 5 of the processing air outlet member and the processing air outlet 13 in sequence; wherein, the air outlet of the processing fan 12 is connected to the first cavity 3, and the processing air outlet 13 is connected to the third cavity 5. A first primary filter 18 can also be installed between the processing air inlet 11 and the processing fan 12. The first primary filter 18 can filter out dust particles larger than 5 microns in the gas to be dehumidified to prevent the processing area of ​​the dehumidification wheel 2 from being blocked.

[0067] It should be noted that the specific process of dehumidifying the dehumidified gas after passing through the processing air duct assembly is as follows: the high-humidity gas enters the first cavity 3 through the processing air inlet 11 under the action of the processing fan 12. During this process, the first primary filter 18 can filter the larger dust particles in the high-humidity gas. The high-humidity gas then enters the third cavity 5 after being dehumidified by the processing area of ​​the dehumidification wheel 2, and is subsequently discharged through the processing air outlet 13 to complete the gas dehumidification. As a preferred mode, the processing air duct assembly in the dehumidifier chassis 1 is an airflow path mode with lower air intake and upper exhaust.

[0068] The regeneration air duct assembly includes a regeneration air inlet 14, a heating element 15, a regeneration fan 16 and a regeneration air outlet 17. The regeneration gas flows sequentially through the regeneration air inlet 14, the heating element 15, the regeneration zone of the dehumidification wheel 2, the second cavity 4 of the treatment air inlet, the regeneration fan 16 and the regeneration air outlet 17. The heating element 15 is connected to the side port 8, the second cavity 4 is connected to the air inlet of the regeneration fan 16, and a second primary filter 19 is installed between the regeneration air inlet 14 and the heating element 15. The second primary filter 19 can filter out dust particles larger than 5 microns in the regeneration inlet gas to prevent the regeneration zone of the dehumidification wheel 2 from being blocked.

[0069] It should be noted that the specific process of the regeneration air intake regenerating the regeneration zone of the dehumidification wheel 2 through the regeneration air duct assembly is as follows: the regeneration air intake enters the side port 8 through the regeneration air inlet 14 under the action of the regeneration fan 16, and the heating element 15 heats the regeneration air intake during this process. The heated regeneration air intake passes through the regeneration zone of the dehumidification wheel 2 and is dehumidified. Subsequently, the regeneration outlet gas with a higher humidity is discharged through the second cavity 4 and the regeneration air outlet 17 under the action of the regeneration fan 16. As a preferred mode, the regeneration air duct assembly in the dehumidifier chassis 1 is an airflow path mode of upper air intake and lower exhaust.

[0070] The dehumidifier installs the air inlet and outlet processing parts on the dehumidification wheel 2. The air inlet and outlet processing parts are both integrally formed plastic parts, avoiding the use of a more complex sheet metal structure, thereby allowing the dehumidifier to form a better internal seal and not be affected by the outer shell seal. An independent air circulation system is formed through the air duct components above and below the dehumidification wheel 2, so that the dehumidifier has better sealing performance and can continue to work when the outer door of the chassis 1 is open, thereby improving the overall practicality of the dehumidifier.

[0071] Furthermore, the heating element 15 is preferably a PTC heater, and the regeneration temperature of the dehumidification wheel 2 is 70-90°C, the regeneration fan 16 is an outer rotor EC (Electrical Commutation) fan (a centrifugal fan using a digital brushless DC outer rotor motor), and the dehumidification wheel 2 of the dehumidifier is a medium-temperature dehumidification wheel with a relatively low regeneration temperature (70-90°C). Compared with the regeneration temperature of the traditional high-temperature regeneration dehumidification wheel being not less than 120°C, the regeneration gas at a lower temperature can achieve the dehumidification regeneration of the regeneration zone of the dehumidification wheel 2. Therefore, a PTC heater is preferably used here. The PTC has an overheating protection function and has no safety hazards. The heat exchange efficiency of the PTC is higher than that of the traditional electric heating tube, and it is more energy-saving. Among them, the regeneration fan 16 can also adopt an outer rotor EC fan accordingly. The EC fan is more energy-saving than the AC (Alternating Current) fan. At the same time, the EC motor has a smaller structural size, which is easy to install, so that the overall weight of the dehumidifier is reduced, and the corresponding logistics costs can be further reduced.

[0072] In other preferred embodiments, the dehumidifier may further include a touch screen 20, a digital tube 21, and an emergency stop switch 22. The touch screen 20, the digital tube 21, and the emergency stop switch 22 may all be connected to the controller of the dehumidifier.

[0073] Specifically, the touch screen 20 is arranged on the cabinet 1 to control the operation of the dehumidifier. The touch screen 20 is preferably arranged on the front part of the cabinet 1 to facilitate the staff to adjust.

[0074] The digital tube 21 is arranged on the chassis 1 on one side of the touch screen 20 to display the temperature and humidity at the processing air inlet 11, the processing air outlet 13, the regeneration air inlet 14 and the regeneration air outlet 17. The digital tube 21 is preferably arranged on the front part of the chassis 1, so that the staff can observe the display status of the digital tube 21.

[0075] The emergency stop switch 22 is arranged on the chassis 1 to control the emergency stop of the dehumidifier. The emergency stop switch 22 is preferably arranged at a relatively low position on the chassis 1, so that the staff can press the emergency stop switch 22 to stop the equipment in an emergency.

[0076] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
