Description

Technical Field

[0001] The present invention mainly relates to the technical field of air conditioner self-cleaning, and in particular to an air conditioner ventilation filtration self-cleaning dust removal and sterilization system. Background Art

[0002] Traditional central air conditioning systems typically use filters to filter the incoming air. During operation, the filters first capture dust and other particles, filtering the incoming air. Most of the captured dust accumulates on the windward side of the filter. As the air conditioner runs longer, the filters become clogged, increasing airflow resistance and leading to increased energy consumption.

[0003] When the filter panel cannot work effectively, it needs to be cleaned or replaced manually in time. From an economic point of view, the labor cost during maintenance and the replacement cost of consumables are very expensive, and the maintenance time is long, which means the air conditioner cannot work for a long time. Summary of the Invention

[0030] An embodiment of the present application provides an air-conditioning ventilation filtration self-cleaning dust removal and sterilization system, including a filter screen 10, a reciprocating cleaning mechanism 20 is provided on the rear side of the filter screen 10, and the reciprocating cleaning mechanism 20 includes four fixed blocks 21 respectively installed at the four corners of the filter screen 10, two first screw rods 23 respectively connected to the fixed blocks 21 on both sides, a lifting plate 24 slidably connected between the two first screw rods 23, a first motor 22 connected to the first screw rod 23, and a cleaning brush 25 installed on the inner side of the lifting plate 24.

[0031] A spray mechanism 30 and a foam mechanism 40 are also installed around the filter screen plate 10. The spray mechanism 30 includes connecting blocks 31 installed on both sides of the top of the lifting plate 24, a second screw rod 32 rotatably connected between the connecting blocks 31, a slider 37 slidably connected to the second screw rod 32, a spray head 38 installed on the inner side of the slider 37, a second motor 34 connected to the second screw rod 32, a water tank 39, and a connecting pipe 310 connected to the water tank 39 and the spray head 38 respectively. A water pump connected to the connecting pipe 310 is provided in the water tank 39. The foam mechanism 40 has the same structure as the spray mechanism 30 and is installed at the bottom of the lifting plate 24. Cleaning liquid is provided in the water tank 39 of the foam mechanism 40.

[0032] The electrical components of this device are all connected to the air conditioner power supply and are electrically connected to a conventional PLC controller.

[0033] Specifically, the system further includes two air pressure detection units, which are respectively installed on both sides of the filter plate 10.

[0034] It should be noted that, in this embodiment, the two air pressure detection units are respectively used to detect the air pressure on both sides of the filter plate 10 .

[0035] Two air pressure thresholds are set in the controller. When the air pressure difference on both sides detected by the two air pressure detection units is greater than the higher air pressure threshold, the cleaning and dust removal system will operate until the air pressure difference on both sides is less than the lower air pressure threshold, at which time the cleaning and dust removal system will stop operating.

[0036] For details, please refer to the attached Figure 2 The reciprocating cleaning mechanism 20 further includes two transmission gears 26 connected to the two first screw rods 23 respectively, and a transmission crawler 27 sleeved outside the two transmission gears 26.

[0037] It should be noted that, in this embodiment, the two first screw rods 23 can be rotated synchronously through the transmission of the two transmission gears 26 and the transmission track 27 , thereby making the lifting of the lifting plate 24 more stable.

[0038] For details, please refer to the attached Figure 1, the cleaning brush 25 contacts the inner side of the filter screen plate 10.

[0039] It should be noted that, in this embodiment, it is ensured that the cleaning brush 25 can clean the brush on the filter screen plate 10 .

[0040] For details, please refer to the attached Figure 5 A driven gear 36 is installed on one side of the second screw rod 32, and a driving gear 35 is installed on the output shaft of the second motor 34. The driving gear 35 and the driven gear 36 are meshed with each other.

[0041] It should be noted that, in this embodiment, the second motor 34 can drive the second screw rod 32 to rotate through the engagement of the driving gear 35 and the driven gear 36 without affecting the displacement of the slider 37 to the two sides of the second screw rod 32 .

[0042] For details, please refer to the attached Figure 5 A stabilizing block 33 is installed on the rear side of the second motor 34 , and the stabilizing block 33 is connected to the lifting plate 24 .

[0043] It should be noted that, in this embodiment, the second motor 34 can be stably connected to the lifting plate 24 through the stabilizing block 33 .

[0044] For details, please refer to the attached Figure 4 A guide rod 314 is installed between the two connecting blocks 31 at the bottom of the second screw rod 32, and the guide rod 314 is slidably connected to the slider 37.

[0045] It should be noted that, in this embodiment, the guide rod 314 can limit the direction of the slider 37 so that the spray head 38 faces the filter plate 10 .

[0046] For details, please refer to the attached Figure 4 A water filling port 312 is provided on the top of the water storage tank 39 , a sealing cover is provided on the water filling port 312 , and a sight glass 311 is provided on the side of the water storage tank 39 .

[0047] It should be noted that, in this embodiment, the water tank 39 needs to be set in the external area of ​​the air conditioner so that water can be added conveniently. The water level of the water tank 39 can be easily known through the sight glass 311, so that water can be easily injected through the water inlet 312.

[0048] For details, please refer to the attached Figure 5 The sprinkler head 38 is connected to an L-shaped fixed pipe 313 , and the connecting pipe 310 is connected to the L-shaped fixed pipe 313 .

[0049] It should be noted that, in this embodiment, the L-shaped fixing pipe 313 can prevent the connecting pipe 310 in the area of ​​the sprinkler head 38 from affecting components such as the second screw rod 32 .

[0050] For details, please refer to the attached Figure 6 The connecting pipe 310 is a telescopic hose, and a rubber connector 315 is installed at the end of the connecting pipe 310. The rubber connector 315 is inserted into the L-shaped fixed pipe 313 to connect the two.

[0051] It should be noted that, in this embodiment, the rubber connector 315 can ensure that there is no water leakage between the connecting pipe 310 and the L-shaped fixed pipe 313. At the same time, the connecting pipe 310 of the telescopic hose can ensure that it will not be broken when the sprinkler head 38 moves left and right.

[0052] The specific operation mode of the present invention is as follows:

[0053] When the air pressure difference on both sides detected by the two air pressure detection units is greater than the higher air pressure threshold, the cleaning and dust removal system operates; through the operation of the first motor 22, the first screw rod 23 rotates, and the transmission of the transmission gear 26 and the transmission track 27 can achieve synchronous rotation of the two first screw rods 23, so that the lifting plate 24 drives the cleaning brush 25 to continuously rise and fall to clean the filter plate 10.

[0054] At the same time, the water pump in the water tank 39 operates to spray the foam liquid and water onto the filter plate 10 through the spray head 38. At the same time, the second motor 34 operates to rotate the second screw rod 32, thereby moving the slider 37 left and right, so that the spray head 38 reciprocates left and right to clean the filter plate 10.

[0055] The water at the bottom can be discharged through a set channel until the air pressure difference on both sides is less than the lower air pressure threshold, and the cleaning and dust removal system stops operating.

[0056] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
