Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidifier technology, and in particular to a bottom-inlet vertical dehumidifier unit. Background Technology
[0002] A floor-standing dehumidifier is an air dehumidification device designed to stand vertically, primarily used to reduce the relative humidity in indoor environments. Compared to traditional portable or ceiling-mounted dehumidifiers, floor-standing dehumidifiers typically have a larger processing capacity and higher efficiency, making them suitable for larger spaces such as commercial spaces, warehouses, offices, and larger residential spaces.
[0003] Existing vertical dehumidifiers typically use a bottom air intake method to more effectively collect and treat humid air near the ground. However, because the bottom air intake has a single air intake direction and a limited air intake range, it reduces the dehumidification effect and efficiency of the room.
[0004] Therefore, a bottom-inlet vertical dehumidifier unit has now been developed that can expand the air intake range at the bottom of the casing, thereby improving the dehumidification effect and efficiency. Utility Model Content
[0005] To overcome the shortcomings of existing vertical dehumidifiers, such as the single air intake direction and limited air intake range of the bottom air inlet, which reduces the dehumidification effect and efficiency of the room, this utility model provides a bottom-intake vertical dehumidifier unit that can expand the air intake range at the bottom of the casing and improve the dehumidification effect and efficiency.
[0006] The technical solution is: a bottom-inlet vertical dehumidifier unit, including a shell, a fan, a water outlet pipe, a dehumidification filter assembly and an air inlet assembly. The fan is connected to the inner side of the upper left part of the shell, a water collection tank is opened on the inner side of the lower left part of the shell, and the water outlet pipe is connected to the lower left part of the shell. The water outlet pipe is connected to the water collection tank. The shell is equipped with a dehumidification filter assembly that can dehumidify and filter humid air. The shell is also equipped with an air inlet assembly that can increase the air inlet range.
[0007] Furthermore, it also includes casters, with multiple casters rotatably connected to the underside of the outer casing.
[0008] Furthermore, the dehumidification and filtration assembly includes a compressor dehumidifier, a storage bin, a filter screen, a filter, and a baffle plate. The compressor dehumidifier is connected to the inner left side of the housing, the storage bin is snapped into the upper left side of the housing, the storage bin and the compressor dehumidifier are located below the fan, the filter screen is snapped into the lower right side of the housing, the filter is snapped into the lower right side of the housing, the filter is located above the filter screen, and a baffle plate is snapped into the front right side of the housing.
[0009] Furthermore, a handle is provided on the front side of the storage bin.
[0010] Furthermore, a handle is provided on the upper front side of the shield.
[0011] Furthermore, the air intake assembly includes a support plate, louvers, a motor, and a gear ring. The support plate is connected to the lower right side of the housing, and the louvers are rotatably connected to the support plate. The motor is connected to the lower right front side of the support plate, and a gear is provided on the motor output shaft. The gear ring is connected to the louvers, and the gear ring meshes with the gear.
[0012] The beneficial effects are as follows: 1. When the outer shell is exposed to air, the motor is started to make the gear and the gear ring mesh and move, which drives the louvers to rotate on the support plate, so that humid air from different directions enters the outer shell, thereby expanding the air intake range at the bottom of the outer shell and improving the dehumidification effect and efficiency.
[0013] 2. When the storage box, filter screen, and filter need to be cleaned or replaced, this utility model allows for convenient and quick replacement and cleaning of the dehumidification filter components by removing the storage box from the outer shell, pulling the baffle upwards, and then removing the filter screen and filter from the outer shell. This improves equipment maintenance efficiency. Attached Figure Description

Detailed Implementation
[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0021] A bottom-inlet vertical dehumidifier unit, such as Figures 1-5As shown, it includes a housing 1, casters 2, a fan 3, a water outlet pipe 10, a dehumidification filter assembly, and an air inlet assembly. Four casters 2 are rotatably connected to the lower side of the housing 1. The fan 3 is connected to the inner side of the upper left part of the housing 1. A water collection tank 9 is opened on the inner side of the lower left part of the housing 1. The water outlet pipe 10 is connected to the lower left part of the housing 1 and communicates with the water collection tank 9. A dehumidification filter assembly is provided on the housing 1, and an air inlet assembly is also provided on the housing 1.
[0022] like Figures 1-4 As shown, the dehumidification and filtration assembly includes a compressor dehumidifier 4, a storage bin 5, a filter screen 6, a filter 7, and a baffle plate 8. The compressor dehumidifier 4 is connected to the inner left side of the outer casing 1. The storage bin 5 is snapped onto the upper left side of the outer casing 1. A handle is provided on the front side of the storage bin 5 for easy gripping. The storage bin 5 and the compressor dehumidifier 4 are located below the fan 3. The filter screen 6 is snapped onto the lower right side of the outer casing 1. The filter 7 is snapped onto the lower right side of the outer casing 1. The filter 7 is located above the filter screen 6. The baffle plate 8 is snapped onto the front right side of the outer casing 1. A handle is provided on the front upper part of the baffle plate 8 for easy gripping.
[0023] like Figure 1 and Figure 5 As shown, the air intake assembly includes a support plate 11, a louver 12, a motor 13, and a gear ring 14. The support plate 11 is connected to the lower right side of the outer casing 1. The louver 12 is rotatably connected to the support plate 11. The motor 13 is connected to the lower right front side of the support plate 11. A gear is provided on the output shaft of the motor 13. The gear ring 14 is connected to the louver 12 and meshes with the gear.
[0024] When using this invention, firstly, the outer casing 1 is pushed to the dehumidification area using the casters 2. Then, the fan 3 is started, allowing humid air to enter from the bottom of the outer casing 1. The filter 6 intercepts larger impurities in the humid air, and the filter 7 intercepts smaller impurities. Next, the compressor dehumidifier 4 is started to dehumidify the humid air. The desiccant in the storage tank 5 dehumidifies the humid air, and the condensate falls into the water collection tank 9 and is then discharged from the outlet pipe 10. When it is necessary to clean or replace the storage tank 5, the filter 6, and the filter 7, the storage tank 5 is removed from the outer casing 1. Pull the baffle plate 8 upwards, and then remove the filter screen 6 and the filter 7 from the outer casing 1. Clean and replace the storage box 5, the filter screen 6, and the filter 7, thereby enabling convenient and quick replacement and cleaning of the dehumidification filter components and improving equipment maintenance efficiency. When air enters the outer casing 1, the motor 13 can be started, causing the gear to mesh with the gear ring 14, driving the louvers 12 to rotate on the support plate 11, allowing humid air from different directions to enter the outer casing 1, thereby expanding the air intake range at the bottom of the outer casing 1 and improving the dehumidification effect and efficiency.
