[0033] Example 1

[0034] Reference Figure 1 , 2 , which is the first embodiment of the present invention, and provides an inverter air dehumidification mechanism in a small space, including a cleaning module 100, the cleaning module 100 includes a backflush mechanism 102 and an air pipe assembly 105, the air outlet end of the backflush mechanism 102 is connected to the air pipe assembly 105, and the cleaning module 100 is installed on the wall surface of the inverter room;

[0035] The filter plate installed in the air inlet 201 of the inverter compartment is cleaned by the cleaning module 100 to prevent dust accumulation on the surface of the filter plate from affecting air circulation and heat dissipation.

[0036] The air inlet and outlet assembly 200 includes an air inlet 201 and an air outlet 202 for the inverter compartment. The air inlet and outlet assembly 200 is arranged on the wall surface of the inverter compartment. The cleaning module 100 is arranged on the outer surface of the air inlet 201 for the inverter compartment. A filter plate is arranged in the air inlet 201 for the inverter compartment.

[0038] The refrigeration air conditioner 400 is arranged on or inside two opposite walls at both ends of the variable frequency room. By using the refrigeration air conditioner 400, the room can be prevented from overheating in extremely hot weather in summer.

[0039] Example 2

[0040] Reference Figures 3-4 , which is the second embodiment of the present invention, is based on the previous embodiment and provides an inverter air dehumidification mechanism for a small space.

[0041] The filter assembly 501 includes a filter frame 501a, filter cotton 501e and a middle filter screen 501f. There are two middle filter screens 501f. Both ends of the middle filter screens 501f are arranged on the inner shell of the filter frame 501a. The filter cotton 501e is arranged between the two middle filter screens 501f.

[0042] The filter cotton 501e is limited by two middle filters 501f, and the filter cotton 501e is evenly filled in the two middle filters 501f to ensure stable dehumidification and filtration of the air. The mesh holes on the surface of the middle filter 501f ensure smooth passage of air, so that the amount of air processed by the equipment within a unit time is guaranteed.

[0043] The circulation component 502 includes a transmission motor 502a, a fan impeller 502b and a vertical pipe 502e. The fan impeller 502b is arranged at the output end of the transmission motor 502a. One end of the vertical pipe 502e is connected to the bottom of the filter frame 501a. The fan impeller 502b is driven to rotate by starting the transmission motor 502a. The air is extracted by the rotation of the fan impeller 502b so that it can be quickly circulated and discharged. It is connected to the filter frame 501a through the vertical pipe 502e, so that the air of the two is connected. The number of vertical pipes 502e is not less than eight, so that the air circulation is faster and the dehumidification cycle of the air is convenient.

[0044] The exhaust component 503 includes a second connecting pipe 503a, an annular exhaust pipe 503b and an exhaust blowout pipe 503c. The exhaust blowout pipe 503c is arranged in a circular shape and equidistantly on the surface of the annular exhaust pipe 503b, so that after dehumidification, the air is discharged from multiple points outside the annular exhaust pipe 503b, so that the air circulation effect is better and the indoor air circulation is convenient. One end of the second connecting pipe 503a is connected to the annular exhaust pipe 503b.

[0045] The circulation component 502 also includes a mounting rod 502c and a circulation chamber 502d. One end of the mounting rod 502c is fixedly connected to the transmission motor 502a, and the other end of the mounting rod 502c is fixedly connected to the circulation chamber 502d. The connection and fixation of the mounting rod 502c can ensure the stable rotation of the transmission motor 502a and the stable operation of the equipment.

[0046] One end of the vertical pipe 502e close to the circulation chamber 502d is connected to the circulation chamber 502d, and the surface of the bottom of the circulation chamber 502d is connected to one end of the second connecting pipe 503a. By connecting the circulation chamber 502d with the vertical pipe 502e and the second connecting pipe 503a, the filtering cycle of the dehumidification module 100 is smoother, and the air smoothly enters and exits the filtering component 501, the circulation component 502 and the exhaust component 503, ensuring the efficiency of the equipment when dehumidifying the air.

[0047] The filter assembly 501 also includes an upper filter 501d, which is arranged on the surface of the top of the filter frame 501a and forms an air intake channel. Through the use of the upper filter 501d, it can effectively prevent external debris from falling into the inner cavity of the filter frame 501a during the air circulation and dehumidification process of the equipment, thereby ensuring the clean use of the equipment.

[0048] The filter assembly 501 also includes an opening door 501b and a hinge 501c. The hinge 501c is arranged on the surface of the filter frame 501a. One end of the opening door 501b is movably connected to the hinge 501c. By using the opening door 501b and the hinge 501c, it is more convenient for the user to open the filter frame 501a and replace the filter cotton 501e. After absorbing moisture, the filter cotton 501e can be reused by drying in the sun, which is more energy-saving and environmentally friendly.

[0049] The specific operation process of this embodiment is as follows:

[0050] 1. The fan impeller 502b is driven to rotate by starting the transmission motor 502a, and the rotation of the fan impeller 502b allows air to circulate. The air enters the inner cavity of the annular exhaust pipe 503b along the second connecting pipe 503a, and is finally discharged through the exhaust outlet pipe 503c.

[0051] 2. After the air is discharged, negative pressure appears in the inner cavity of the circulation chamber 502d. The outside air passes through the upper filter 501d and enters the inner cavity of the filter frame 501a. After being filtered by the filter cotton 501e, it enters the inner cavity of the circulation chamber 502d through the vertical pipe 502e, completing the air circulation cycle.

[0052] 3. Through the continuous rotation of the transmission motor 502a, the indoor air is continuously circulated. The filter 501d on the air inlet of the equipment is located at the top, and the exhaust pipe 503c at the air outlet is located at the bottom, so that the air circulation effect is better and the continuous filtering effect is ensured.

The third bevel gear 102e and the back-blowing fan 102a are both arranged on the surface of the movable shaft 102b. Through the rotation of the back-blowing fan 102a, the indoor air is drawn into the inner cavity of the mounting frame 102f along the through-hole at the bottom of the mounting frame 102f, and finally the air is transmitted to the air pipe assembly 105 located in the room to back-blow the filter plate.

[0059] There are two second bevel gears 102d, and the two second bevel gears 102d are respectively arranged at the two ends of the connecting rod 102c, the third bevel gear 102e is meshed with the second bevel gear 102d located in the inner cavity of the mounting frame 102f, and the other second bevel gear 102d is meshed with the first bevel gear 101f. Through the meshing of the second bevel gear 102d and the first bevel gear 101f, a mechanical transmission force is obtained, thereby causing the back-blowing fan 102a to rotate to extract air.

[0060] The absorption mechanism 103 includes a positive blowing fan 103a, a transmission shaft 103b, an output rod 103c, a fourth bevel gear 103d, a fifth bevel gear 103e and a protective shell 103f. The fourth bevel gear 103d and the positive blowing fan 103a are both arranged on the surface of the transmission shaft 103b.

[0061] The air in the protective shell 103f is discharged by the rotation of the positive blowing fan 103a, so that negative pressure is generated in its inner cavity. The air pipe assembly 105 connected thereto extracts air, and the dust is extracted into the inner cavity of the protective shell 103f and discharged, thereby extracting and processing the dust generated by the filter plate during the cleaning process.

[0062] There are two fifth bevel gears 103e, which are respectively arranged at both ends of the output rod 103c. The fourth bevel gear 103d is meshed with the fifth bevel gear 103e located in the inner cavity of the protective shell 103f, and the other fifth bevel gear 103e is meshed with the first bevel gear 101f. Through the meshing of the fifth bevel gear 103e and the first bevel gear 101f, a mechanical transmission force is obtained, thereby causing the forward blowing fan 103a to rotate to extract air.

[0064] One end of the cleaning rod 104e is bent to form an L-shaped strip 104e-1, and a cleaning brush 104e-2 is installed on the surface of the L-shaped strip 104e-1. The L-shaped strip 104e-1 and the cleaning brush 104e-2 are in close contact with the surface of the filter cartridge 104d. Through the opening of the L-shaped strip 104e-1 and the cleaning brush 104e-2, the surface of the filter cartridge 104d can be cleaned better, thereby preventing dust accumulation on the surface of the filter cartridge 104d from affecting its use effect.

By determining the installation directions of the two, the air outlet and air inlet directions of the cleaning module 100 can be guaranteed. The back-blowing fan 102a blows out air for cleaning, and the forward-blowing fan 103a absorbs air for dust collection, making the equipment more convenient and environmentally friendly.
