Description

Technical Field

[0001] This application belongs to the field of air dehumidification technology, and more specifically, relates to a rotary dehumidifier. Background Technology

[0002] Rotary dehumidifiers are an important branch of the dehumidification field, mainly used in industrial projects with special air requirements. A rotary dehumidifier's rotor has a dehumidification zone and a regeneration zone. A heating device is needed to heat the regeneration zone and dry the moisture. After the rotor rotates, the heating device heats a new regeneration zone, and the cycle continues.

[0003] Heating devices require a fan to blow airflow toward the end with the heating element. When a large air volume is required, the fan speed must be increased. However, excessive fan speed results in significant noise. Existing rotary dehumidifiers struggle to balance air volume and noise levels. Utility Model Content

[0004] The purpose of this application is to provide a rotary dehumidifier that can balance airflow and noise levels.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a rotary dehumidifier is provided, comprising: a rotary wheel and a processing airflow generating device and a regeneration airflow generating device disposed on the same side of the rotary wheel. The processing airflow generating device includes a processing airflow pipe and a processing fan installed in the processing airflow pipe. The regeneration airflow generating device includes a regeneration airflow pipe, and a regeneration fan and a heating box respectively disposed at both ends of the regeneration airflow pipe. The heating box has a built-in heating element. The regeneration airflow pipe and the heating box constitute a regeneration air duct, and the processing airflow pipe is connected to the regeneration air duct.

[0006] In one embodiment, the processing airflow pipe has a through hole on one side, and the heating box has a through hole corresponding to the position of the through hole, and the processing airflow pipe is connected to the regeneration air duct through the through hole.

[0007] In one embodiment, the through hole is an arc-shaped hole.

[0008] In one embodiment, the arc-shaped hole bends away from the center of the processing fan.

[0009] In one embodiment, the inner wall of the processing airflow pipe is provided with a baffle corresponding to the through hole. The baffle and the inner wall of the processing airflow pipe form a receiving cavity with openings on both sides. The opening on one side of the receiving cavity is adapted to the size and shape of the through hole, and the opening on the other side of the receiving cavity forms an inlet for the airflow in the processing airflow pipe to flow into the heating box.

[0010] In one embodiment, the processing airflow pipe includes a volute and a mounting shell. The volute is connected to the front side of the mounting shell, the processing fan is disposed on the volute, and the mounting shell has a through hole in a region corresponding to the volute. The rear side of the mounting shell protrudes to form a rim, a portion of the heating box extends into the mounting shell, and the rim has a notch to avoid the heating box.

[0011] In one embodiment, the heating box has an arc-shaped wall on the side near the center of the processing fan.

[0012] In one embodiment, the radius of curvature of the arc-shaped wall gradually increases from near the center of the processing fan to far away from the center of the processing fan.

[0013] In one embodiment, the bottom wall of the regeneration airflow pipe near the heating box is provided with a flow-guiding slope.

[0014] In one embodiment, the heating box is integrally formed with the regeneration airflow pipe.

[0015] The beneficial effects of the rotary dehumidifier provided in this application are as follows: Compared with the prior art, the rotary dehumidifier of this application connects the treatment airflow pipe and the regeneration air duct. A portion of the airflow in the treatment airflow pipe of the treatment airflow generator flows to the regeneration air duct, and the rotation speed of the regeneration fan can be adjusted and reduced, thereby reducing noise.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] Please refer to the following: Figures 1 to 4The rotary dehumidifier provided in this application embodiment will now be described. The rotary dehumidifier includes a rotor 10, a processing airflow generating device 20, and a regeneration airflow generating device 30. The rotor 10 has a dehumidification zone and a regeneration zone, and is rotatably mounted on a frame 11. The processing airflow generating device 20 and the regeneration airflow generating device 30 are located on the same side of the rotor 10. The processing airflow generating device 20 includes a processing airflow pipe 21 and a processing fan 22 mounted on the processing airflow pipe 21. In this embodiment, one end of the processing airflow pipe 21 has a processing airflow inlet, and the other end has a processing airflow outlet, with the processing airflow outlet facing upwards.

[0029] The regenerative airflow generating device 30 includes a regenerative airflow pipe 31, and a regenerative fan 32 and a heating box 33 respectively disposed at both ends of the regenerative airflow pipe 31. The heating box 33 is disposed corresponding to the regeneration zone and has a built-in heating element 330, which may be, but is not limited to, a PTC heating element. The regenerative airflow pipe 31 has a regenerative airflow inlet on the rear side away from the heating box 33, and the heating box 33 has a regenerative airflow outlet on the rear side. The regenerative airflow pipe 31 and the heating box 33 together form a regenerative air duct. The processing airflow pipe 21 is connected to the regenerative air duct. Thus, driven by the processing fan 22, a portion of the airflow in the processing airflow pipe 21 flows to the regenerative air duct. Even when the rotation speed of the regenerative fan 32 is reduced, it can still meet the airflow requirements, that is, it can meet the airflow requirements while reducing noise, thus balancing airflow and noise.

[0030] The processing airflow duct 21 and the regeneration air duct can be directly connected, or indirectly connected through a pipe or a hollow connector. When using the direct connection method, a through hole can be opened on the heating box 33, or through holes can be opened on both the heating box 33 and the regeneration airflow duct 31. The through holes of the two can be combined into one, or the through holes of the two can be set separately.

[0031] Compared with the prior art, the rotary dehumidifier provided in this application connects the processing airflow pipe 21 and the regeneration air duct. A portion of the airflow in the processing airflow pipe 21 of the processing airflow generator 20 flows to the regeneration air duct, and the rotation speed of the regeneration fan 32 can be adjusted and reduced, thereby reducing noise. In this way, the noise can be significantly reduced while meeting the airflow requirements, thus balancing airflow and noise and improving the user experience of the product.

[0032] See Figures 2 to 4A through hole 201 is provided on the rear side of the processing airflow pipe 21, and a through hole 331 is provided on the heating box 33 corresponding to the position of the through hole 201. That is, the through hole 331 is set directly opposite the through hole 201 of the processing airflow pipe 21. In this way, the processing airflow pipe 21 is connected to the regeneration air duct through the through hole 331, and part of the airflow driven by the processing fan 22 flows into the heating box 33 through the through hole 331, thereby increasing the airflow rate in the regeneration air duct. The shape of the through hole 201 on one side of the processing airflow pipe 21 and the through hole 331 of the heating box 33 can be the same or different. In this embodiment, the shape of the through hole 201 on one side of the processing airflow pipe 21 and the through hole 331 of the heating box 33 are the same, and the through hole 201 and the through hole 331 are also the same size.

[0033] See Figure 1 , Figure 2 and Figure 5 A baffle 212 is provided on the inner wall of the processing airflow pipe 21 corresponding to the through hole 201. The baffle 212 and the inner wall of the processing airflow pipe 21 form a receiving cavity 213 with openings on both sides. The opening on one side of the receiving cavity 213 is adapted to the size and shape of the through hole 201, and the opening on the other side of the receiving cavity 213 forms an inlet for the airflow in the processing airflow pipe 21 to flow into the heating box 33. The baffle 212 provided in the processing airflow pipe 21 can play a certain guiding role for the airflow, that is, it can guide a part of the airflow in the processing airflow pipe 21 to the heating box 33, thereby increasing the air volume in the regeneration air duct. It can be understood that the baffle 212 may not be provided in the processing airflow pipe 21.

[0034] The airflow processing duct 21 includes a volute 210 and a mounting shell 211. The volute 210 is connected to the front side of the mounting shell 211. The processing fan 22 is disposed in the volute 210. A through hole 201 is provided in the area of ​​the mounting shell 211 corresponding to the volute 210. A baffle 212 is disposed inside the volute 210, and the axial length of the baffle 212 is equal to the axial length of the volute 210. A rim 214 protrudes from the rear side of the mounting shell 211. The rim 214 of the mounting shell 211 is connected to the frame 11 of the rotary dehumidifier. A part of the heating box 33 extends into the mounting shell 211, and the other part of the heating box 33 is located outside the mounting shell 211. A notch 215 is provided in the rim 214 to avoid the heating box 33. The processing fan 22 includes a processing motor 220 and a fan 221. The mounting shell 211 has a circular opening corresponding to the position of the fan 221, thereby forming a flow channel for indoor air to be drawn in by the rotational power of the fan 221. The longitudinal cross-sectional area of ​​the mounting housing 211 is larger than that of the volute 210, meaning that the orthographic projection of the volute 210 onto the rotor 10 is entirely within the orthographic projection of the mounting housing 211 onto the rotor 10. The tops of the volute 210 and the mounting housing 211 define an exhaust channel 202 for discharging indoor air drawn in by the fan 221 outside the rotary dehumidifier.

[0035] Please see Figures 2 to 4 The through hole 331 on the heating box 33 is set as an arc-shaped hole, so that the communication area between the heating box 33 and the processing airflow pipe 21 is larger. The arc-shaped hole is bent away from the center of the processing fan 22, so that the air blown from the processing fan 22 can enter the heating box 33 more smoothly, thereby increasing the air volume.

[0036] The heating box 33 has an arc-shaped wall 332 on the side near the center of the processing fan 22. This means the heating box 33 is not a standard rectangular box; its corner near the center of the processing fan 22 is rounded, not a right angle. The arc-shaped wall 332 on the heating box 33 guides the airflow within the heating box 33, reducing air resistance when the airflow hits the inner surface of the heating box 33, thus reducing the amount of backflow and allowing more airflow to exit from the airflow outlet of the heating box 33. At least a portion of the through-hole 331 on the heating box 33 is located on the arc-shaped wall 332, meaning at least a portion of the through-hole 331 extends to the arc-shaped wall 332. In one embodiment, the radius of curvature of the arc-shaped wall 332 on the heating box 33 gradually increases from near the center of the processing fan 22 to away from the center of the processing fan 22.

[0037] The regeneration airflow pipe 31 has a guide ramp 313 at the bottom near the heating box 33. The higher end of the ramp 313 is connected to the side wall of the heating box 33 with an opening. In this way, by setting the ramp 313, the amount of backflow air can be reduced, allowing more airflow to flow smoothly into the heating box 33.

[0038] The heating box 33 has a rectangular cross-section, and one end of the ramp 313 is connected to the two adjacent side walls of the heating box 33. That is, most of the higher part of the ramp 313 is connected to one side wall of the heating box 33, and the remaining part is connected to the other adjacent side wall of the heating box 33. This increases the air intake area and thus increases the air volume.

[0039] The heating box 33 and the regeneration airflow pipe 31 are integrated, which saves manufacturing steps. The one-piece molding method also eliminates the need for docking and installation, and also eliminates the need for a sealing structure at the docking point. Specifically, the regeneration airflow pipe 31 and the heating box 33 can be formed by two connected first housings 311 and second housings 312. A mutually cooperating positioning structure can be provided between the first housing 311 and the second housing 312 to facilitate positioning and assembly.

[0040] Please see Figure 1 , Figure 2 The rotary dehumidifier also includes a heat exchanger 40 located on the other side of the rotary wheel 10. A processing airflow generator 20 provides processing airflow through the rotary wheel 10 to complete dehumidification and discharges the dehumidified airflow outside the rotary dehumidifier. The regeneration airflow inlet is connected to the outlet of the heat exchanger 40, and the regeneration airflow outlet is connected to the inlet of the heat exchanger 40. A drive mechanism 50 for driving the rotary wheel 10 to rotate is also provided on the frame 11. This drive mechanism 50 includes a drive motor and a drive wheel. A gear is fitted around the outer circumference of the rotary wheel 10, and the drive wheel meshes with this gear. The output shaft of the drive motor is connected to the drive wheel. The drive motor drives the drive wheel to rotate, which in turn drives the gear to rotate, thus realizing the rotation of the rotary wheel 10.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
