Description

Technical Field

[0001] The present invention relates to the technical field of disinfection and sterilization, and in particular to a central air-conditioning fan disinfection and sterilization auxiliary device and a use method thereof. Background Art

[0002] Central air conditioning is a centralized air conditioning system consisting of one or more outdoor units and multiple indoor units. Its working principle is to control the indoor air temperature and humidity by circulating the refrigerant between the indoor and outdoor units. When the air conditioner is turned on, the refrigerant will be sucked into the compressor and compressed into a high-temperature and high-pressure gas, and then dissipate heat through the condenser and become a high-pressure liquid. Then, after the high-pressure liquid passes through the expansion valve, the pressure drops sharply and becomes a low-temperature and low-pressure liquid refrigerant. Finally, the liquid refrigerant flows through the evaporator, absorbs the indoor heat and evaporates into a gaseous state, which reduces the indoor temperature. In the daily use and maintenance process, first clean the scale attached to the air conditioner water pipe, then clean the air outlet and return air louver, then remove the filter to vacuum and brush with warm water, and finally rinse the outdoor unit casing with a tap water gun.

[0003] Prior art, such as a central air-conditioning fan disinfection and sterilization auxiliary device with publication number CN 219624184 U, the device can reduce the dust in the air from entering the interior of the air-conditioning unit by setting a dustproof net in the air inlet pipe, and prolong the circulation time of air in the air inlet pipe by setting a plurality of staggered supporting plates, and disinfect and sterilize by an ultraviolet disinfection lamp installed on the top of the supporting plate. At the same time, a sealing unit is set inside the air outlet pipe that passes through the bottom plate of the air-conditioning unit, and by cutting off the power of the electromagnet, the sealing plate will open the sealed chamber under the action of gravity, and the sealing plate is connected to the inner wall of the sealed chamber by an elastic rope. When the air outlet of the air outlet pipe is large, the sealing plate will be blown and the elastic rope will be stretched to expand the opening of the sealed chamber, thereby ensuring that the sealing plate does not interfere with the normal operation of the air outlet pipe. During normal use, when the air-conditioning unit is turned off, the sealing plate will be restored to a half-open state under the action of the elastic rope, and the electromagnet will be powered at this time, so that the electromagnet has magnetic force, and then absorbs the permanent magnet, so as to seal the sealing chamber to prevent air from entering the interior of the air-conditioning unit through the air outlet duct when not in use. The ultraviolet disinfection method is used to disinfect the air input end, and the air output end of the air outlet duct is sealed to achieve the purpose of disinfection and sterilization of the interior of the air-conditioning unit. However, in actual use, the sealing of the sealing chamber can reduce dust, but the dust accumulated inside the air-conditioning unit still needs to be manually disassembled and cleaned one by one. In addition, after the circulating air is disinfected and sterilized by ultraviolet light, it will still bring out dust and disperse it in the indoor environment, causing damage to people's health.

[0040] Furthermore, an ultraviolet lamp 25 is fixedly installed on the top surface of the inner wall of the fan 1. When the central air conditioner is used daily, turning on the ultraviolet lamp 25 has a sterilization effect. When the air conditioner is shut down for disinfection and maintenance, turning on the ultraviolet lamp 25 can accelerate the evaporation of residual detergent, and the ventilation and deodorization effect is better. A through groove is opened at the rear end of the cleaning chamber 6 and is parallel to the crank 17. The through groove facilitates the operator to push the crank 17. A cleaning plate 26 is slidably connected to the bottom surface of the cleaning chamber 6. The cleaning plate 26 uniformly collects dust and impurities, and cleaning is more time-saving and labor-saving.

[0041] Furthermore, a method for using a central air-conditioning fan disinfection and sterilization auxiliary device comprises the following steps:

[0042] Step 1: Start the cylinder 10, the telescopic rod contracts to drive the connecting rod 11 connected to the front end to move upward, drive the rotating shaft to rotate, cooperate with the fixed frame 9 to make the shutter 12 flip downward, and close the air outlet;

[0043] Step 2: Open the end of the ventilation pipe 4 away from the fan 1, find the traction rope that runs through the ventilation pipe 4, thread the threaded block 14 fixedly connected to one end of the traction rope to the pipe brush 15, start the reel 13, shorten the traction rope, and make the pipe brush 15 pass through the ventilation pipe 4, sweeping away the dust inside the ventilation pipe 4 and depositing it on the top surface of the movable plate 16;

[0044] Step 3: Push the crank 17 to drive the movable plate 16 to slide along the sliding groove. The front end of the driving rod 18 is meshed with the rear end of the linkage rod 19 through an irregular gear, and the two sets of movable plates 16 are opened synchronously with the rotating movable rod 20, and the accumulated dust falls vertically into the top surface of the cleaning plate 26 on the bottom surface of the cleaning bin 6;

[0045] Step 4: Start the first hydraulic cylinder 21 and the second hydraulic cylinder. The first hydraulic cylinder 21 drives the cleaning rod 22 to move horizontally to the left and right, and the second hydraulic cylinder drives the cleaning rod 22 to move vertically up and down.

When the louver 12 is flipped upward, the air outlet is opened without affecting the unit driving the fan blades 2 to perform normal exhaust.

[0048] Furthermore, the opening area of ​​the top surface of the cleaning bin 6 is the same as the bottom surface area of ​​the fan 1, the length of the movable plate 16 is greater than the length of the fan 1, and the driving rod 18 and the linkage rod 19 are mirror-symmetrical, so that when the movable plate 16 is synchronously closed, the bottom surface of the fan 1 is in a closed state, and when the movable plate 16 is synchronously opened, the bottom surface of the fan 1 is completely opened, and all dust can fall vertically into the cleaning bin 6.

[0049] Furthermore, the diameter of the threaded block 14 is larger than the diameter of the inner wall of the traction ring, which prevents the traction rope from detaching from the ventilation pipe 4 after contraction. The diameter of the duct brush 15 is the same as the diameter of the inner wall of the ventilation pipe 4, ensuring that when the duct brush 15 moves to one end of the traction ring, it can push all the dust on the inner wall of the ventilation pipe 4 into the fan 1. The length of the bristles of the cleaning brush 23 is the same as the width of the inner wall of the fan 1. The length of the bristles ensures that the moving range of the cleaning brush 23 can cover the entire inner wall of the fan 1, and the dust is cleaned comprehensively without dead ends.

The dust and impurities fall vertically into the cleaning bin 6 for unified collection. The first hydraulic cylinder 21 and the second hydraulic cylinder are closed, and the cleaning rod 22 and the cleaning brush 23 are driven to descend into the cleaning bin 6, and the crank 17 is pushed to drive the two sets of movable plates 16 to close synchronously, and the cylinder 10 is started to drive the shutter 12 of the flip mechanism 3 to flip upward to open the air outlet, and the ultraviolet lamp 25 is started to perform ventilation, disinfection and sterilization.
