The circular air duct of the tank body 5 penetrates and is fixedly connected to the right side of the inner wall of the casing 1, and the square air duct of the tank body 5 penetrates and is fixedly connected to the left side of the bottom surface of the chamber of the round shell 2. A water outlet pipe 8 is penetrated and fixedly installed at the bottom of the left side of the tank body 5, and a resistance heater 9 is fixedly installed on the left side of the top surface of the tank body 5. A driving module 10 is fixedly installed in the middle of the top surface of the tank body 5. The driving module 10 includes a heat dissipation shell and a motor. The heat dissipation shell is fixedly installed in the middle of the top surface of the tank body 5, and the motor is fixedly installed on the top of the heat dissipation shell. The motor shaft penetrates and is rotatably installed in the middle of the top surface of the tank body 5. A straight ring 11 is fixed on the bottom of the inner wall of the tank body 5, and the straight ring 11 is fixed on the top A concave ring 12 is installed on the surface for rotation, and a cylinder 13 is fixed on the top surface of the concave ring 12. The middle of the top surface of the cylinder 13 is fixedly connected to the bottom surface of the motor shaft of the driving module 10, and a semiconductor refrigeration plate 14 is fixedly installed on the top of the cylinder 13. The tank body 5 is located on the left side of the casing 1, and the resistance heater 9 is located above the circular air duct of the tank body 5. The resistance heater 9 is fixedly connected to the right side of the inner wall of the casing 1. The cylinder 13 contacts the hot air over a large area during the forward rotation, so that the cylinder 13 contacts the hot air evenly, and the moisture in the hot air will form frost on the surface of the cylinder 13. The condensed hot air quickly dries and enters the square air duct of the tank body 5. The dry air is sucked into the L-shaped air duct 4 to avoid the dehumidification device not evenly cooling the hot air and causing water vapor to enter the cabin.

[0032] A frost scraper assembly is arranged on both sides of the top surface of the straight ring 11, and the frost scraper assembly includes vertical strips 15, which are fixed on both sides of the top surface of the straight ring 11, and a plurality of round rods 16 are penetrated and slidably installed on the side where the vertical strips 15 are close to each other, and a circular plate 17 is fixed on the side where the round rods 16 are far away from each other, and a spring 18 is fixed on the side where the circular plates 17 are close to each other, and the spring 18 is fixedly connected to the vertical strips 15, and a chamfered rod 19 is fixed on the side where the round rods 16 are close to each other, and the chamfered rod 19 is located on the left and right sides of the cylinder 13, and the chamfered rod 19 scrapes off the frost on the cylinder 13, so that the frost containing salt is quickly removed, so as to avoid the frost containing salt from damaging the refrigeration parts during the dehumidification process of the dehumidification device, resulting in poor condensation and water removal effect.

[0033] When in use, the casing 1 supports the round shell 2, and the round shell 2 supports the L-shaped air duct 4. The staff connects the L-shaped air duct 4 to the ventilation duct of the ship and starts the electric fan 3 on the casing 1. The motor shaft of the electric fan 3 starts to rotate forward, and the motor shaft drives the fan to rotate forward. The fan rotates forward in the chamber of the round shell 2, and the fan of the electric fan 3 sucks air into the L-shaped air duct 4, and the L-shaped air duct 4 transports the air to the ventilation duct of the ship. Since the equipment is in the process of condensing the hot air, it is difficult to condense the hot air evenly, which can easily cause the moisture in the hot air to flow into the ventilation duct. At this time, the casing 1 supports the tank body 5, and the tank body 5 supports the water outlet pipe 8. The resistance heater 9 on the tank body 5 is started, and the resistance heater 9 starts to heat up. The resistance heater 9 transfers heat to the circular air duct of the tank body 5. Under the suction action of the electric fan 3, air enters from the circular air duct of the tank body 5, and the circular air duct of the tank body 5 The air is heated rapidly, and at the same time, the driving module 10 on the tank body 5 is started, the motor shaft on the driving module 10 starts to rotate forward, the motor shaft drives the cylinder 13 to rotate forward, the cylinder 13 drives the concave ring 12 to rotate forward, the concave ring 12 rotates forward on the straight ring 11, and during the forward rotation of the cylinder 13, the semiconductor refrigeration plate 14 in the cylinder 13 is started, the semiconductor refrigeration plate 14 starts to cool, and the semiconductor refrigeration plate 14 reduces the temperature of the surface of the cylinder 13, so that the cylinder 13 is in contact with the hot air over a large area during the forward rotation, so that the cylinder 13 is in contact with the hot air evenly, and the moisture in the hot air will form frost on the surface of the cylinder 13, and the condensed hot air is quickly dried and enters the square air duct of the tank body 5, and the dry air is sucked into the L-shaped air duct 4 to prevent the equipment from not evenly cooling the hot air, thereby avoiding the problem of water vapor entering the cabin due to the dehumidification device not evenly cooling the hot air.

[0034] As the ship is sailing on the sea, the salt content in the sea surface air is high. During the dehumidification process, the salt in the air will be attached to the water vapor. When the air is condensed, the salt will be attached to the refrigeration parts together with the water vapor, which may cause poor quality of the refrigeration parts. While the motor shaft on the driving module 10 drives the cylinder 13 to rotate forward, the straight ring 11 supports the vertical strip 15. During the forward rotation of the cylinder 13, the chamfered rod 19 is against the cylinder 13. Under the action of the extrusion force, the chamfered rod 19 drives the round rod 16 to slide The round rod 16 slides in the vertical bar 15. At the same time, the round rod 16 drives the circular plate 17 to move. The spring 18 on the circular plate 17 is stretched. Under the elastic force of the spring 18, the chamfered rod 19 will be tightly pressed against the rotating cylinder 13, so that the chamfered rod 19 scrapes off the frost on the cylinder 13, so that the salt-containing frost is quickly removed to prevent the refrigeration parts of the equipment from being corroded by the salt-containing frost, thereby avoiding the problem that the refrigeration parts are damaged by the salt-containing frost during the dehumidification process of the dehumidifier, resulting in poor condensation and water removal effect.

[0035] See also Figure 1-Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a water guide device 6 is provided in the middle of the bottom surface of the cylinder 13, and the water guide device 6 includes a vertical rod 61, a disk 62, an L-shaped rod 63 and a sweeping plate 64. The vertical rod 61 is fixed in the middle of the bottom surface of the cylinder 13, the disk 62 is fixed on the bottom surface of the vertical rod 61, the L-shaped rod 63 is fixed on the bottom surface of the disk 62, a through groove is provided on the right side of the L-shaped rod 63, and the sweeping plate 64 is embedded in the inner wall of the through groove of the L-shaped rod 63. The vertical rod 61 is located in the middle of the inner part of the straight ring 11, and the sweeping plate 64 is located on the right side of the water outlet pipe 8. When the sweeping plate 64 rotates forward, the sweeping plate 64 stirs the accumulated frost, allowing the frost to melt quickly and be discharged from the water outlet pipe 8, so as to avoid the frost scraped off by the dehumidifier when in use from accumulating together and causing poor drainage effect of the equipment.

[0036] The water guiding device 6 also includes a triangular ring 65, a T-shaped rod 66 and a concave round block 67. The triangular ring 65 is fixed on the top of the outer wall of the vertical rod 61, the T-shaped rod 66 is fixed in the middle of the bottom surface of the triangular ring 65, and the concave round block 67 is fixed on the bottom end of the tank body 5. The inner wall of the concave round block 67 is rotatably connected to the bottom end of the T-shaped rod 66. The triangular ring 65 on the T-shaped rod 66 remains stable during the forward rotation, so that the sweeping plate 64 on the L-shaped rod 63 can stably stir the frost, reduce the shaking of the L-shaped rod 63, and avoid the dehumidification device from shaking violently when draining water, causing damage to the equipment.

[0037] An anti-backflow device 7 is provided on the top of the outer wall of the water-guiding device 6. The anti-backflow device 7 includes a ring frame 71, a semi-cylindrical shell 72, a semi-arc filter 73, a lime column 74 and a round cover 75. The ring frame 71 is fixed on the top of the outer wall of the L-shaped rod 63, the ring frame 71 is located above the triangular ring 65, the semi-cylindrical shell 72 is fixed on the end of the ring frame 71 away from the L-shaped rod 63, the semi-arc filter 73 is fixedly installed on the front of the semi-cylindrical shell 72, the lime column 74 is fixedly installed on the bottom end of the semi-cylindrical shell 72, and the round cover 75 is fixedly installed on the top surface of the semi-cylindrical shell 72. During the forward rotation of the lime column 74, the lime column 74 increases the contact area with the gas, and the lime column 74 absorbs the moisture overflowing from the frost to prevent the condensed water vapor of the dehumidifier from being sucked into the cabin when in use.

[0038] The anti-backflow device 7 also includes a protrusion 76, a semi-arc spring piece 77 and a ring 78. The protrusions 76 are fixed on the left and right sides of the inner wall of the semi-cylindrical shell 72, the semi-arc spring piece 77 is fixed on the side where the two protrusions 76 are close to each other, and the ring 78 is fixed on the end where the two semi-arc spring pieces 77 are close to each other. The ring 78 is located in the middle of the outer wall of the lime column 74. Under the elastic force of the semi-arc spring piece 77, the ring 78 limits the movement of the lime column 74 to avoid damage to the lime column 74 during the dehumidification process of the dehumidification device, resulting in poor water absorption effect.

[0039] Since the frost scraped off by the chamfering rod 19 will accumulate in the tank body 5, the accumulated frost is difficult to melt quickly. While the motor shaft on the driving module 10 drives the cylinder 13 to rotate forward, the cylinder 13 drives the vertical rod 61 to rotate forward, the vertical rod 61 drives the disc 62 to rotate forward, the disc 62 drives the L-shaped rod 63 to rotate forward, and the L-shaped rod 63 drives the sweeping plate 64 to rotate forward, so that during the forward rotation of the sweeping plate 64, the sweeping plate 64 stirs the accumulated frost, allowing the frost to melt quickly and be discharged from the water outlet pipe 8, preventing the frost from accumulating and causing poor drainage effect of the equipment, thereby avoiding the problem of poor drainage effect of the equipment caused by the frost scraped off by the dehumidifier when in use.

[0040] While the disc 62 drives the L-shaped rod 63 to rotate forward, the L-shaped rod 63 drives the triangular ring 65 to rotate forward, and the triangular ring 65 drives the T-shaped rod 66 to rotate forward. The T-shaped rod 66 rotates forward in the concave round block 67. Under the restriction of the concave round block 67, the triangular ring 65 on the T-shaped rod 66 remains stable during the forward rotation, allowing the sweeping plate 64 on the L-shaped rod 63 to stir the frost stably, reducing the shaking of the L-shaped rod 63 and preventing the equipment from shaking violently when stirring the frost to drain water, thereby avoiding the problem of severe shaking of the dehumidification device during drainage and causing damage to the equipment.

[0041] Since the frost scraped off by the chamfering rod 19 stays in the tank body 5 for a period of time, the moisture on the frost can be easily sucked out again under the suction action of the electric fan 3. While the disc 62 drives the L-shaped rod 63 to rotate forward, the L-shaped rod 63 drives the ring frame 71 to rotate forward, the ring frame 71 drives the semi-cylinder shell 72 to rotate forward, the semi-cylinder shell 72 drives the semi-arc filter 73, and at the same time, the semi-cylinder shell 72 drives the lime column 74 to rotate forward, and the semi-cylinder shell 72 drives the round cover 75 to rotate forward. During the forward rotation of the lime column 74, the lime column 74 increases the contact area with the gas, and the lime column 74 absorbs the moisture overflowing from the frost, preventing the frost in the equipment from overflowing and the gas with moisture from entering the ship, thereby avoiding the problem of condensed water vapor being sucked into the cabin when the dehumidifier is in use.

[0042] While the semi-cylindrical shell 72 drives the lime column 74 to rotate forward, the semi-cylindrical shell 72 drives the protrusion 76 to rotate forward, the protrusion 76 drives the semi-arc spring piece 77 to rotate forward, and the semi-arc spring piece 77 drives the ring 78 to rotate forward. During the forward rotation of the ring 78, under the elastic force of the semi-arc spring piece 77, the ring 78 restricts the movement of the lime column 74 to prevent the lime column 74 from moving and being damaged during the rotation, thereby avoiding the problem of poor water absorption effect caused by damage to the lime column 74 during the dehumidification process of the dehumidification device.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
