Description

Technical Field

[0001] The utility model relates to the technical field of rotary wheel dehumidifiers, in particular to a rotary wheel dehumidifier with a noise reduction structure. Background Art

[0002] A rotary wheel dehumidifier is a common household appliance used to remove moisture from the air. It works based on the principle of moisture absorption and dehumidification by a rotary wheel. Inside the rotary wheel dehumidifier, there is a rotary wheel coated with a moisture-absorbing material, usually silica gel or other moisture-absorbing materials. When air passes through the rotary wheel, the moisture is adsorbed onto the rotary wheel, and then the moisture is removed from the rotary wheel by heating or other means, thus achieving the dehumidification effect. However, in order to reduce the noise generated by the intake and exhaust, a noise reduction structure is set at the intake end and the exhaust end for noise reduction treatment. The traditional physical noise reduction method is to install sound-absorbing cotton, but after long-term use, the sound-absorbing cotton will also age and break, making it inconvenient to maintain and replace. Summary of the Utility Model

[0006] To solve the above technical problems, the technical solution provided by the utility model is: a rotary wheel dehumidifier with a noise reduction structure, including a rotary wheel dehumidifier body. Both ends of the rotary wheel dehumidifier body are fixedly connected with air ducts. A diversion fan cooperating with the air ducts is arranged in the rotary wheel dehumidifier body. The air ducts are provided with mounting holes arranged in an annular array. Sound-absorbing cotton blocks are slidably inserted into the mounting holes. A support bar is fixedly connected to the bottom surface of the mounting holes. Sound insulation cover cylinders are slidably sleeved on the outer walls of the air ducts. One end of each air duct is slidably sleeved with a mounting retaining ring located on one side of the sound insulation cover cylinder. One end of each air duct is provided with grooves arranged in an annular array. Fixed insertion blocks are slidably inserted into the grooves. Fixed springs cooperating with the fixed insertion blocks are fixedly connected in the grooves. Fixed slots cooperating with the fixed insertion blocks are arranged on the inner walls of the mounting retaining rings.

[0007] As an improvement, the cross-section of the fixed insertion block is a right trapezoid, and the side away from the rotary wheel dehumidifier body is the inclined surface end.

[0008] As an improvement, an inclined landslide cooperating with the fixed insertion block is arranged in the fixed slot.

[0009] As an improvement, fixed retaining rings are fixedly connected to both ends inside the air ducts. Bellows are fixedly connected between the two fixed retaining rings on both sides. The bellows are provided with uniformly arranged through holes.

[0010] As an improvement, an adjusting handle is fixedly connected to the outer wall of the mounting retaining ring.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5As shown in the figure, a rotary dehumidifier with a noise reduction structure includes a rotary dehumidifier body 1. A sound insulation layer 17 is provided inside the rotary dehumidifier body 1. Air ducts 2 are fixedly connected to both ends of the rotary dehumidifier body 1 respectively. A diversion fan matching with the air duct 2 is provided inside the rotary dehumidifier body 1. Installation holes 3 arranged in an annular array are provided on the air ducts 2. Sound-absorbing cotton blocks 4 are slidably inserted into the installation holes 3. A support bar 5 is fixedly connected to the bottom surface of the installation hole 3. Fixed retaining rings 13 are fixedly connected to both ends inside the air duct 2. A corrugated pipe 14 is fixedly connected between the two fixed retaining rings 13 on both sides. Uniformly arranged through holes 15 are provided on the corrugated pipe 14.

[0022] Sound insulation cover cylinders 6 are slidably sleeved on the outer walls of the air ducts 2. Installation retaining rings 7 located on one side of the sound insulation cover cylinders 6 are slidably sleeved on one end of the air ducts 2. An adjusting handle 12 is fixedly connected to the outer wall of the installation retaining ring 7. Grooves 8 arranged in an annular array are provided at one end of the air ducts 2. Fixed insertion blocks 9 are slidably inserted into the grooves 8. Fixed springs 10 matching with the fixed insertion blocks 9 are fixedly connected to the grooves 8. Fixed slots 11 matching with the fixed insertion blocks 9 are provided on the inner walls of the installation retaining rings 7. The cross section of the fixed insertion block 9 is a right trapezoid, and the side away from the rotary dehumidifier body 1 is the inclined end. An inclined landslide 16 matching with the fixed insertion block 9 is provided in the fixed slot 11.

[0023] In specific use, the sound insulation layer 17 can further reduce the noise inside the rotary dehumidifier body 1. When inhaling and exhaling air, the noise generated by inhaling and exhaling air is further eliminated through the corrugated pipe 14, the through holes 15, and the sound-absorbing cotton blocks 4. When the sound-absorbing cotton blocks 4 need to be replaced, rotate the handle 12 to drive the installation retaining ring 7 to rotate, so that the fixed insertion block 9 slides along the inner wall of the fixed slot 11. When the fixed insertion block 9 slides onto the inclined landslide 16, the inclined landslide 16 squeezes the fixed insertion block 9 to slide into the groove 8. At the same time, the fixed insertion block 9 squeezes the fixed spring 10 to generate a compressive deformation. As the inclination of the inclined landslide 16 continuously increases, the installation retaining ring 7 drives the fixed insertion block 9 to continuously slide along the inclined landslide 16 until the fixed insertion block 9 is completely inserted into the groove 8. Then pull out the installation retaining ring 7 outward, and then pull out the sound insulation cover cylinder 6 outward. Then take out the sound-absorbing surface block to be replaced from the installation groove. After the replacement is completed, sleeved the sound insulation cover cylinder 6 on the outer wall of the air duct 2 again, so that the other end of the sound insulation cover cylinder 6 closely adheres to the outer wall of the rotary dehumidifier body 1. Then sleeve the installation retaining ring 7 on one end of the air duct 2, and push the installation retaining ring 7 to slide along the outer wall of the air duct 2, so that the end of the air duct 2 abuts against the inclined surface of the fixed insertion block 9, squeezing the fixed insertion block 9 to be completely inserted into the groove 8, so that one side of the installation retaining ring 7 tightly abuts against one end of the sound insulation cover cylinder 6. Rotate the installation retaining ring 7. When the groove 8 coincides with the fixed slot 11, under the restoring elastic force of the fixed spring 10, push the fixed insertion block 9 into the fixed slot 11 to complete the installation, which is time-saving and labor-saving and easy to operate.
