[0040] The leads and water pipes of the dehumidification module 3 are arranged on one side along the X-axis direction, and the leads and water pipes of the dehumidification module are connected to the outside through plug-in terminals. Therefore, when removing, the leads and water pipes of the dehumidification module are unplugged, and the disassembly can be realized, avoiding the problem of the limitation of the leads and water pipes of the dehumidification module 3, and the dehumidification module 3 can be smoothly withdrawn directly from the box body 1 and maintained.

[0041] The fan module 2 extracts the air in the accommodation space 100 through the air outlet 101, making the accommodation space 100 form a negative pressure, so that the air near the air inlet 102 enters the accommodation space 100 through the air inlet 102; after the air enters the accommodation space 100, it first enters the filter module 4 for filtration. After the air filters out dust particles, it then enters the dehumidification module 3 for dehumidification treatment, and then is discharged from the air outlet 101.

[0042] Specifically, the dehumidification module 3 includes a dehumidification module frame 31, an evaporation and condensation assembly 32, a compressor 33, a water pump 34, a float level switch 35, a main control board 36 and a water receiving tray 37;

[0043] The dehumidification module frame 31 is slidably assembled at the dehumidification module installation station; the water receiving tray 37 and the compressor 33 are respectively arranged in the dehumidification module frame 31, and the evaporation and condensation assembly 32 is arranged in the water receiving tray 37; the compressor 33 is communicated with the evaporation and condensation assembly 32; the detection end of the float level switch 35 is arranged in the water receiving tray 37, and the water inlet end of the water pump 34 is arranged in the water receiving tray 37;

[0044] The main control board 36 is arranged on one side of the dehumidification module frame 31 along the X-axis direction; the main control board 36 is electrically connected to the compressor 33, and the float level switch 35 is electrically connected to the water pump 34 through the main control board 36.

[0045] The dehumidification principle of the dehumidification module 3 can refer to the dehumidification device of existing dehumidifiers. The compressor is responsible for generating the power for the refrigerant cycle. The evaporation and condensation component 32 plays a role in completing the heat exchange process of the refrigerant. Water vapor enters the evaporation and condensation component 32, and through the cooling effect of the refrigeration cycle system, the water vapor condenses into liquid water. The liquid water flows into the water receiving tray 37. When the water level threshold of the water receiving tray 37 reaches the set value, the float level switch 35 is triggered, and the water pump is started. The water pump 34 pumps the liquid water out of the water receiving tray 37 to prevent the liquid water from accumulating in the dehumidification module 3. The main control board 36 is used to control the start or stop of the compressor 33; the float level switch 35 is triggered because the water level in the water receiving tray 37 reaches the set value, and it converts it into an electrical signal and transmits it to the main control board 36. The main control board 36 sends a start signal to the water pump 34 to achieve the purpose of controlling the opening or closing of the water pump 34 and enabling the water pump 34 to drain the accumulated water in the water receiving tray 37.

[0046] The dehumidification module frame 31 plays a role in accommodating the evaporation and condensation component 32, the compressor 33, the water pump 34, the float level switch 35, the main control board 36, and the water receiving tray 37. When disassembling, the dehumidification module 3 can be entirely removed by pulling out the dehumidification module frame 31.

[0047] Specifically, the evaporation and condensation component 32 includes a condenser, an evaporator, an electronic expansion valve 321, and a capillary tube. The condenser is connected to the output end of the compressor 33. The evaporator and the condenser are connected by the capillary tube. The electronic expansion valve 321 is connected between the condenser and the evaporator 33. The evaporator is connected to the input end of the compressor 33; the electronic expansion valve 321 is electrically connected to the main control board 36.

[0048] The main structure of the evaporation and condensation component 32 is the evaporator and the condenser, which can refer to existing dehumidifiers. The compressor 33 compresses the refrigerant into a high-temperature and high-pressure gas, which becomes a low-temperature and high-pressure gas after dissipating heat through the condenser, becomes a low-temperature and low-pressure liquid after throttling through the capillary tube, and returns to the compressor after absorbing heat through the evaporator, forming a cycle. The evaporator and the condenser are connected by the capillary tube, and the electronic expansion valve 321 is connected between the evaporator and the condenser. The electronic expansion valve uses the electrical signal generated by the regulated parameter to control the voltage or current applied to the expansion valve, thereby regulating the refrigerant. Moreover, it has a wide adjustment range, fast response, and high precision. Therefore, it can better adjust the refrigeration capacity according to different load environments, thus broadening the use in different places.

[0049] Specifically, the box body 1 includes a box top plate 11, a box bottom plate 12, a first side plate 13, and a second side plate 14;

[0050] The first side plate 13 is disposed at one end of the box body bottom plate 12 along the Y-axis direction, the second side plate 14 is disposed at the other end of the box body bottom plate 12 along the Y-axis direction, the air outlet 101 is disposed on the first side plate 13, and the air inlet 102 is disposed on the second side plate 14; the box body top plate 11 is covered above the first side plate 13 and the second side plate 14; the maintenance door 10 is installed on both sides of the box body top plate 11 along the X-axis direction; the box body bottom plate 12, the box body top plate 11, the first side plate 13, the second side plate 14 and the maintenance door 10 cooperate to form an accommodation space 100;

[0051] The first top guide rail 111, the second top guide rail 112 and the upper filter chute 113 are respectively disposed on the box body top plate 11, and the first bottom guide rail 121, the second bottom guide rail 122 and the lower filter chute 123 are respectively disposed on the box body bottom plate 12.

[0052] The box body 1 is composed of a box body bottom plate 12, a box body top plate 11, a first side plate 13 and a second side plate 14, and the box body bottom plate 12, the box body top plate 11, the first side plate 13, the second side plate 14 and the maintenance door 10 cooperate to form an accommodation space 100 to accommodate the fan module 2, the dehumidification module 3 and the filter module 4. The first bottom guide rail 121 is located below the orthographic projection of the first top guide rail 111, and the second bottom guide rail 122 is located below the orthographic projection of the second top guide rail 112, cooperating to form a dehumidification module installation station, and the dehumidification module frame 31 can be slidably installed at the dehumidification module installation station. The upper filter chute 113 is located below the orthographic projection of the lower filter chute 123, thereby forming a filter module installation station, and the filter module 4 can be slidably installed at the filter module installation station.

[0053] Specifically, the filter module 4 includes a primary filter 41 and a high-efficiency filter 42, and the primary filter 41 is located on the side of the high-efficiency filter 42 close to the air inlet 102.

[0054] By using the primary filter 41 and the high-efficiency filter 42 in combination, the filtering effect can be improved. The primary filter 41 and the high-efficiency filter 42 are commonly used in dehumidifiers and fresh air devices. The primary filter is mainly used to filter dust particles larger than 5μm in the air, effectively blocking large particles from entering the air purification system. The high-efficiency filter mainly removes particles larger than 0.5μm through a microscopic flocculent structure, intercepting the tiny dust contained in the air passing through the filter. The filtering effect of the high-efficiency filter is about 99.97% or more of DOP, that is, it can intercept the vast majority of particles in the air. By performing primary filtration through the primary filter 41 and secondary filtration through the high-efficiency filter 42, larger particles in the air can be removed, reducing the load on the high-efficiency filter 42.

[0055] Specifically, the fan module 2 includes a fan body 21, a first fan fixing plate 22, a second fan fixing plate 23, and a fan air outlet plate 24; the first fan fixing plate 22 and the second fan fixing plate 23 have the same structure and are both angle plates with an "L"-shaped cross section.

[0056] The fan air outlet plate 24 is provided with ventilation holes, the air inlet end of the fan body 21 is sleeved on the outer periphery of the ventilation holes, and on one side of the fan air outlet plate 24 along the X-axis, first extension plates 241 extend inward respectively, and on the other side of the fan air outlet plate 24 along the X-axis, second extension plates 242 extend inward respectively; one side support surface of the first fan fixing plate 22 is detachably connected to one side of the air outlet 101 along the X-axis, and the other side support surface of the first fan fixing plate 22 is detachably connected to the first extension plate 241; one side support surface of the second fan fixing plate 23 is detachably connected to the other side of the air outlet 101 along the X-axis, and the other side support surface of the second fan fixing plate 23 is detachably connected to the second extension plate 242.

[0057] The above structure adopts a symmetrical disassembly and assembly structure. When performing maintenance on one side of the X-axis, only need to open the maintenance door 10 on one side of the X-axis, first remove the bolts fixing the first fan fixing plate 22 to the first side plate 13, and then remove the bolts for fixing the second extension plate 242 and the second fan fixing plate 23, then the fan body 21 can be separated from the box body 1. Similarly, when performing maintenance on the other side of the X-axis, open the maintenance door 10 on the other side of the X-axis, first remove the bolts fixing the second fan fixing plate 23 to the first side plate 13, and then remove the bolts for fixing the first extension plate 241 and the first fan fixing plate 22, then the fan body 21 can be separated from the box body 1.

[0058] With the above structure, only need to open one side maintenance door 10 to disassemble the fan module 2, which improves the disassembly efficiency and reduces the operations required for disassembly.

[0059] Specifically, it further includes a fresh air valve module 5, and the fresh air valve module 5 is arranged at the air inlet 102 for controlling the opening or closing of the air inlet 102.

[0060] With the above structure, the opening or closing of the air inlet 102 can be controlled through the fresh air valve module 5, thereby realizing the air intake of the dehumidifier. When the dehumidifier is closed, the air inlet 102 can be controlled to close, which can prevent air from entering the accommodation space 100 and achieve the purpose of avoiding the air intake of the dehumidifier. When the dehumidifier is opened, the air inlet 102 can be controlled to open, which can enable air to enter the accommodation space 100.
