Description

Technical Field

[0001] The present invention relates to the technical field of automobile air-conditioning systems, and in particular to a method for automatically removing dust from automobile air-conditioning filter cloth. Background Art

[0002] Conventional automotive air conditioning filter cloths are used to filter dust and impurities from the air. Over time, these filters accumulate dust, impacting air conditioning performance and in-car air quality. One conventional approach involves using sensors to monitor dust accumulation on the filter cloth and, when a preset threshold is reached, initiates a dust removal process.

[0003] The dust removal procedure requires that the filter cloth be removed, or all passengers leave the vehicle, the surface of the filter cloth be blown with high-pressure air flow, and the filter cloth be vibrated with a vibrator to remove the dust.

[0004] The dust that falls off is collected by the dust suction device and stored in the dust box.

[0005] After dust removal is completed, the sensor detects the dust accumulation on the filter cloth again. If the cleaning standard is not met, the dust removal step is repeated.

[0006] The technical solution disclosed in a patent application CN202410690852 is to remove the filter cloth, place it in a centrifuge, and stir the filter cloth during high-speed rotation to throw out the dust.

[0007] It can be seen that the existing technologies all require manual disassembly, cleaning or replacement of filter cloths, which is cumbersome and inefficient. Therefore, it is of great significance to develop an automatic dust removal method. Summary of the Invention

[0008] The present invention is intended to solve the drawbacks of the existing filter cloth dust removal technology, which is either to remove the filter cloth for cleaning, or to use high-pressure air flow to sweep and shake out the dust with a vibrator, which is noisy, cumbersome and inefficient. Instead, a technology is proposed that, at any time, including during driving, when a sensor detects that the filter cloth needs to be cleaned, turns on the filter cloth sliding motor and vacuum pump, slides the filter cloth through the vacuum suction port in turn, and sucks out the dust in reverse.

[0009] The present invention is achieved in that:

[0010] The first step is to construct a structure for automatic dust removal of automobile air-conditioning filter cloth. The structure is as follows: the frame plane of the air-conditioning air-intake frame is an integral plane that surrounds the air-intake window. The filter cloth is long and connected end to end to form a roll. The upper and lower edges of the filter cloth are embedded in the filter cloth slots of the filter cloth clamping strip and then fixed by the filter cloth fixing pins. The inner filter cloth and the filter cloth clamping strip have flat surfaces attached to the frame plane, and the outer filter cloth is attached to the outside of the inner filter cloth, and the two are tightly fitted.

[0011] Prepare continuous pin holes on the filter cloth strips;

[0012] In the second step, an upper large gear and a lower large gear are prepared at one end of the roll of filter cloth to support the filter cloth roll, the upper teeth of the upper large gear are embedded in the pin holes on the upper side of the filter cloth, and the lower teeth of the lower large gear are embedded in the pin holes on the lower side of the filter cloth. The upper large gear and the lower large gear are connected to the main shaft;

[0013] The third step is to prepare a stand, which connects the upper and lower horizontal plates. The upper and lower shaft heads of the main shaft rotate with the upper and lower horizontal plates, so that the main shaft rotates and drives the filter cloth roll to rotate.

[0014] Step 4: Install a motor on the lower horizontal plate, and the small gear of the motor is engaged with the lower teeth;

[0015] Step 6: Fix the upper column on the upper horizontal board and fix the upper column plate on the other end of the upper column;

[0016] The lower column is fixed on the lower horizontal plate, and the other end of the lower column is fixed to the lower column plate; the ends of the upper column plate and the lower column plate are connected to the dust collection sleeve,

[0017] The dust suction sleeve is sleeved on the outside of the main shaft, and an air inlet hole is opened on the dust suction sleeve;

[0018] Step 7: Fix a groove support frame on the stand, which is connected to an air intake groove. The inner cavity of the air intake groove has a lead-out hole, which is connected to an air guide pipe, which is connected to a vacuum pump, and the vacuum pump is also connected to an exhaust pipe.

[0019] An air suction hole is provided on the wall inside the air suction groove;

[0020] The filter cloth is rolled between the suction groove and the dust suction sleeve;

[0021] The eighth step is to install an airflow sensor close to the filter cloth. When the airflow sensor detects that the airflow in the filter cloth is lower than the set value, the controller controls the vacuum pump and the motor to work. Due to the effect of negative pressure, the airflow enters through the air intake space between the dust suction sleeve and the main shaft, and enters the internal space of the suction groove through the air intake hole, the filter cloth, and the suction hole, and is discharged from the outlet hole and finally discharged from the exhaust pipe. When the airflow sensor detects that the filter cloth has been cleaned, the controller controls the vacuum pump and the motor to stop running.

[0022] The filter cloth and the filter cloth clips are both flexible.

[0023] A first pressing roller is arranged on the outside of the filter cloth roll near the upper column, a tensioning roller is inserted into the other end of the filter cloth roll, and a second pressing roller is arranged on the outside of the filter cloth roll near the tensioning roller.

[0024] The width of the connection portion between the upper column plate, the lower column plate and the dust suction sleeve is smaller than the outer diameter of the dust suction sleeve.

[0025] The diameters of the upper and lower large gears are such that when the upper teeth of the upper large gear are embedded in the pin holes above the filter cloth and the lower teeth of the lower large gear are embedded in the pin holes below the filter cloth, the inner surface of the filter cloth roll is just attached to the surface of the dust collection sleeve.

[0026] The air inlet hole on the dust suction sleeve is only provided on one side opposite to the air suction groove.

[0027] The air suction groove is semicircular.

[0028] An adjusting mechanism is provided in the groove supporting frame to adjust the distance between the suction groove and the dust suction sleeve.

[0029] This method is based on a structure in which the filter cloth does not need to be disassembled. By utilizing the inherent flexibility of the filter cloth, the filter cloth is sequentially passed through the suction port of a vacuum pump to reversely suck out the dust and discharge it outside the vehicle. The various components in the structure of the present invention are very compact and small, and do not occupy much space near the original car air conditioner. Moreover, the noise during the automatic dust removal process is very low, which will not affect the overall comfort of the passengers. The present invention greatly extends the service life of the air conditioning filter element and reduces the trouble of frequent replacement of the air conditioning filter element in the car.
