Description

Technical Field

[0001] The invention relates to the technical field of air conditioning units, and in particular to an air conditioning unit and method with anti-corrosion and anti-sand functions. Background Art

[0002] Air conditioning units are one of the indispensable equipment in modern buildings. With the advancement of science and technology, they have developed into a complex system integrating multiple functions such as refrigeration, heating, ventilation, and air purification. Air conditioning units provide people with a comfortable living and working environment by processing air. They are widely used in various places such as homes, offices, factories, hospitals, etc., and have become an indispensable and important facility in modern life.

[0003] The combined air conditioner disclosed in the patent application with reference publication number CN217817129U sets the air inlets of the cold and hot air groups separately, opens one of the air inlets of the cold and hot air groups as needed, and keeps the air inlet of the other air group unventilated so that there will be no dust. The two groups are used alternately, which reduces the accumulation of dust at the air inlets and facilitates cleaning. A filter is set at the air inlets of the two air groups to filter the air entering from the two air inlets, so that the cold and hot air generated by the combined air conditioner remain clean. Water is supplied through a water pipe, and the filter plate is cleaned using a nozzle.

[0004] Comprehensive analysis of the above reference patents shows the following defects:

[0005] Existing air-conditioning units and methods with anti-corrosion and anti-sand functions usually use anti-sand mechanisms to intercept sand and dust particles in the air before sucking outside air into the casing. However, the anti-sand mechanism cannot perform timely and effective self-cleaning during use. After long-term use, sand and dust particles will accumulate, resulting in a decrease in filtering performance, affecting the air filtering efficiency, and it is difficult to dry the passing air in time. The moisture in the air enters the casing and is easy to corrode the temperature control equipment, affecting the performance of the air-conditioning unit. Therefore, it is necessary to provide an air-conditioning unit and method with anti-corrosion and anti-sand functions to solve the above technical problems. Summary of the invention

[0023] The present invention provides an air conditioning unit and method with anti-corrosion and anti-sand functions. Compared with the prior art, it has the following beneficial effects:

[0024] 1. An air conditioning unit and method with anti-corrosion and anti-sand functions. Through the cooperation between the anti-sand mechanism, the sealing plate and the ventilation duct, before the outside air enters the casing through the air inlet window, the anti-sand mechanism can effectively filter the passing air, intercept the sand and dust particles in the air, and perform timely and effective self-cleaning at the same time, ensuring that the filtration efficiency remains at a high level, avoiding the wear of the temperature control equipment in the casing by the sand and dust, and helping to extend the service life of the air conditioning unit. After that, the moisture in the air is absorbed, and the air is dried before entering the rear part of the inner cavity of the casing to prevent the moisture in the air from corroding the temperature control equipment.

[0025] 2. An air conditioning unit and method with anti-corrosion and anti-sand functions, through the cooperation between the lower storage box, the filter cartridge assembly, the arc plate, the first teeth and the fan blades, as the outside air enters, the air first passes through the coarse filter holes to filter out the large particles in the sand and dust, and then passes through the fine filter holes to filter out the small particles in the sand and dust. The filtered air is discharged through the uppermost molecular sieve. During the process, under the action of the airflow, the fan blades can be driven to rotate, and the second disc and the first teeth rotate accordingly. During the rotation of the first teeth, when it rotates to the upper side and meshes with the upper second teeth, the stainless steel The cylinder rotates to a set angle.

[0026] 3. An air conditioning unit and method with anti-corrosion and anti-sand functions. Through the mutual cooperation between a stainless steel cylinder, a shaft, a spiral scraper and a conical baffle, the stainless steel cylinder rotates relative to the spiral scraper. During the process, the spiral scraper can timely scrape the inner wall of the stainless steel cylinder, effectively preventing the fine filter holes from being blocked. The sand and dust particles scraped off by the spiral scraper automatically fall into the lower storage box, which is convenient for unified cleaning later, thereby realizing automatic cleaning of the coarse filter holes and the fine filter holes and ensuring efficient filtration.

[0027] 4. An air conditioning unit and method with anti-corrosion and anti-sand functions. Through the cooperation between the inner cylinder ring, the gear ring, the partition frame, the molecular sieve, the gear and the shielding cover assembly, when the air with the required temperature is discharged through the air outlet, part of the air will enter the shielding cover through the right end of the curved pipe, and the air entering the shielding cover will eventually blow into the two molecular sieves at the bottom, so as to achieve the purpose of automatically ventilating and drying the two molecular sieves at the bottom, and take away the humid air, so that the three molecular sieves can be recycled. After being dried, the molecular sieve is switched to the uppermost part under the drive of the servo motor, so that the passing air can be dehumidified and dried again.

When the first tooth 548 rotates to the lower side and meshes with the second tooth on the lower side, the stainless steel cylinder 5431 can be driven to rotate at a set angle. During the meshing of the second teeth, the stainless steel cylinder 5431 can be driven to rotate in the opposite direction to the set angle, so as to realize the purpose of the reciprocating rotation of the stainless steel cylinder 5431, wherein the outer wall of the stainless steel cylinder 5431 contacts the inner walls of the corresponding two arc plates 544, and the air always passes through the coarse filter hole 5432 first, and then passes through the fine filter hole 5433. During the process, the arc plate 544, which is closely attached to the right part of the stainless steel cylinder 5431, can timely scrape the outer wall of the stainless steel cylinder 5431, and effectively prevent the coarse filter hole 5432 from being blocked. At the same time, the stainless steel cylinder 5431 rotates relative to the spiral scraper 5437, and the spiral scraper 5437 can timely scrape the inner wall of the stainless steel cylinder 5431, and effectively prevent the fine filter hole 5433 from being blocked, thereby ensuring the normal passage of air, and the sand and dust particles scraped by the spiral scraper 5437 fall into the lower storage box 542 for subsequent cleaning;

[0062] Step 2: The filtered air passes through the uppermost molecular sieve 555. During the process of passing through the uppermost molecular sieve 555, the molecular sieve 555 absorbs moisture in the air. Then, the dried air is discharged backward through the ventilation duct 7 to the rear of the sealing plate 6. Then, under the action of the temperature control device, the air temperature is adjusted to reach the required temperature range, and finally discharged through the air outlet 3 to the designated space. The temperature control device belongs to the prior art known to those skilled in the art, and the temperature control device mainly includes a temperature control system, an electric control system, a ventilation system, a fan and other auxiliary components.

[0063] Step 3. When the air reaching the required temperature is discharged through the air outlet 3, part of the air will enter the shielding cover 561 through the right end of the curved pipe 564. The air entering the shielding cover 561 will eventually be blown into the two molecular sieves 555 at the bottom, thereby automatically ventilating and drying the two molecular sieves 555 at the bottom, and taking away the moisture in the two molecular sieves 555 at the bottom. Finally, the moisture will be discharged to the outside through the exhaust pipe, so that the three molecular sieves 555 can be recycled. After being dried, the molecular sieve 555 will be switched to the uppermost part under the timed drive of the servo motor 57 to continue to dehumidify and dry the passing air.
