[0027] This utility model provides a dehumidification device 100, which is applied in a cabinet and can dry and dehumidify the air inside the cabinet. It also features low power consumption and the ability to prevent dust from falling in.

[0028] Please see Figures 1-4 The dehumidification device 100 includes a housing 10, a fan assembly 20, a damper cover 30, and a dehumidification assembly 40. The housing 10 has an air inlet 11 and an air outlet 12. The housing 10 has a chamber, and both the air inlet 11 and the air outlet 12 are connected to the chamber. The air outlet 12 is located on the upper side of the housing 10. The fan assembly 20 is installed in the chamber. The damper cover 30 is rotatably connected to the housing 10 and covers the outer wall of the housing 10. It is configured to open or close the air outlet 12 in response to the operation of the fan assembly 20. The dehumidification assembly 40 is installed in the chamber and located between the air inlet 11 and the air outlet 12.

[0029] Thus, the air inlet 11 and air outlet 12 on the housing 10 are used for air circulation. Air enters through the air inlet 11 and flows out through the air outlet 12, achieving dehumidification and drying within the cavity of the housing 10. The air outlet 12 is located on the upper side of the housing 10 to facilitate air exchange within the cabinet. The dehumidification component 40 is installed between the air inlet 11 and the air outlet 12, so the air flowing within the cavity will inevitably pass through the dehumidification component 40 and be dehumidified by it. The fan 21 accelerates the airflow, thereby improving dehumidification efficiency. The damper cover 30 is placed over the air outlet 12 of the housing 10. When the fan component 20 is running, it can blow open the damper cover 30, allowing the air outlet 12 to connect with the outside. When the fan component 20 is closed, the damper cover 30 naturally descends due to gravity and covers the air outlet 12, thereby preventing dust from the cabinet from falling into the cavity.

[0030] The air inlets 11 are located on the side wall of the housing 10, and there are multiple air inlets 11 evenly spaced. This ensures uniform airflow and allows the dehumidifier 100 to continue to function normally even if some air inlets 11 become blocked.

[0031] Furthermore, a groove is provided on the outer wall of the housing 10, and an air outlet 12 is provided at the bottom of the groove. The damper cover 30 is connected to the side wall of the groove and can be accommodated in the groove. In this way, the groove facilitates the installation of the damper cover 30, and the damper cover 30 is accommodated in the groove and will not protrude from the upper surface of the housing 10, which is more aesthetically pleasing.

[0032] It should be explained that, in this embodiment, the dehumidifier 100 is installed inside the cabinet, with its upper side referring to the upper side along the direction of gravity and its lower side referring to the lower side along the direction of gravity. The groove sidewall of the aforementioned recess is the side surface in the horizontal direction perpendicular to the direction of gravity.

[0033] In other embodiments, the damper cover 30 may also be installed on the bottom surface of the groove or rotatably connected to the inner wall of the housing 10, and is not limited to being installed on the side wall of the groove as described above.

[0034] Two rotating shafts 31 are protruding on the damper cover 30, and are rotatably connected to the side wall of the groove through the two rotating shafts 31.

[0035] Furthermore, the fan assembly 20 includes a fan 21 and a bracket 22. The bracket 22 is connected to the inner wall of the housing 10, forming an installation space. The fan 21 is located within the installation space and connected to the bracket 22 or the housing 10. Thus, the fan 21 is installed using the bracket 22, which forms a stronger connection structure with the inner wall of the housing 10. The fan 21 is installed within the installation space formed between the bracket 22 and the housing 10, resulting in more stable assembly and preventing damage to the fan 21 during later disassembly and maintenance.

[0036] Specifically, the bracket 22 includes a fixing part 221 and a connecting part 222. The connecting part 222 is connected to the fixing part 221 and to the inner wall of the housing 10. The fixing part 221 is spaced apart from the housing 10, and multiple air vents 2211 are provided on the fixing part 221. Thus, the connecting part 222 is used to connect the bracket 22 to the housing 10. In this embodiment, the connecting part 222 has a connecting hole through which a screw is inserted to connect the connecting part 222 to the housing 10. The fixing part 221 is used to support the fan 21 and cooperates with the inner wall of the housing 10 to form an installation space. In other embodiments, bolts or other connecting structures can also be inserted into the connecting hole.

[0037] Furthermore, there are two connecting parts 222, and the two connecting parts 222 are connected to the two diagonally opposite sides of the fixing part 221, thereby increasing the connection strength between the fixing part 221 and the housing 10.

[0038] It should be explained that the two diagonal sides of the fixing part 221 refer to the two ends of the fixing part 221 that are far apart from each other. In this embodiment, the fixing part 221 is configured as a rectangular structure, so the connecting part 222 is connected to the two diagonal sides of the rectangular fixing part 221 that are far apart from each other.

[0039] A limiting block 223 protrudes from the side of the connecting part 222 near the fan 21, and a slope 2231 is formed on the side of the limiting block 223 away from the fan 21 along the axial direction of the fan 21. Thus, the limiting block 223 can confine the fan 21 within the area between the limiting block 223 and the fixing part 221, preventing the fan 21 from falling off and facilitating assembly. During installation, the fan 21 can be first installed into the bracket 22 (i.e., between the limiting block 223 and the fixing part 221), and then the bracket 22 can be connected to the inner wall of the housing 10. The slope 2231 of the limiting block 223 can guide the fan 21 into place, reducing interference between the limiting block 223 and the fan 21 and facilitating the assembly of the fan 21.

[0040] Preferably, limit blocks 223 are provided on the side of the two connecting parts 222 that are close to each other, so as to form two support points with the fan 21, thereby improving the installation stability of the fan 21.

[0041] The dehumidification assembly 40 includes a semiconductor module 41 and a water collection tray 42. The semiconductor module 41 is capable of cooling, and the water collection tray 42 is located below the semiconductor module. Thus, after the semiconductor module 41 is cooled, its contact with the air causes moisture in the air to condense and concentrate on the surface of the semiconductor module 41, thereby achieving dehumidification. The water collection tray 42 can collect the condensate dripping from the semiconductor module 41, preventing overflow.

[0042] A reminder device is installed at the water collection tray 42 to remind the user to replace it based on the water level in the tray. The reminder device can be a weight sensor, positioned at the bottom of the tray. As the amount of condensate in the tray increases, its weight increases. The weight sensor will issue a water level warning based on whether the weight of the tray reaches a preset value, reminding the user to replace the tray and empty the water. Alternatively, the reminder device can be a water level detector, installed on the side wall of the tray 42 at a preset distance from the bottom. When the water level rises to the detector, it will issue a warning, indicating that the tray has just been replaced.

[0043] The dehumidification assembly 40 also includes a water guide tray 43, which is located between the semiconductor module 41 and the water collection tray 42. The bottom of the water guide tray 43 has a water inlet 431, and the bottom of the water guide tray 43 slopes downwards along the direction close to the water inlet 431. In this way, the water guide tray 43 can guide the water dripping from the semiconductor module 41 into the water collection tray 42, preventing water droplets from splashing and overflowing.

[0044] The dehumidification unit 40 also includes a humidity sensor that detects the humidity in the environment and is electrically connected to the semiconductor module 41. Thus, the humidity sensor can control the operation of the semiconductor module 41 based on the ambient humidity. When the humidity inside the cabinet reaches a preset value, the humidity sensor is triggered and controls the semiconductor module 41 to start operating and dehumidify the air. When the humidity inside the cabinet does not reach the preset value, meaning the air in the environment is sufficiently dry, the semiconductor module 41 does not operate, thereby reducing energy consumption.

[0045] Compared to existing technologies, the dehumidifier 100 provided by this invention condenses moisture in the air by utilizing the cooling effect of the semiconductor module 41 and accelerates airflow using the fan 21 to improve dehumidification efficiency. It also includes a damper cover 30 that automatically opens and closes according to the operation of the fan 21. The damper cover opens in response to airflow when the dehumidifier 100 is working and automatically closes due to gravity when the dehumidifier 100 is not working, thus preventing dust from the cabinet from falling into the cavity of the housing 10.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
