[0033] like Figures 1 to 10As shown, the present invention provides a chiller with internal filtering and cleaning function, including an evaporator 1, which is connected to a body 4 through an air suction pressure regulating valve 3. The body 4 includes a compressor and a separator. The compressor in the body 4 is connected to a condenser 2 through a guide pipe 41. The condenser 2 is connected to one end of a drying and filtering device 6 through a guide pipe 5. The other end of the drying and filtering device 6 is connected to the evaporator 1 through a first pipeline.

[0034] The drying and filtering device 6 includes a cleaning transmission structure 61 and a heating sleeve 62. A desiccant is arranged in the heating sleeve 62. A two-way valve 7 is arranged in the first pipeline. The cleaning transmission structure 61 includes a closing structure 611 and a cleaning structure 612. The purpose of the two-way valve 7 is to discharge water vapor through the two-way valve 7 when the molecular sieve and activated alumina in the desiccant are heated to remove moisture.

[0035] The closing structure 611 includes a ball valve 6111, which is connected to one end of the return pipe 8, and the other end of the return pipe 8 is connected to the condenser 2. The ball valve 6111 is transmission-connected to the output end of the driving motor 6112, and the outer ring of the output end of the driving motor 6112 is transmission-connected to the bevel gear transmission group 6113, and the bevel gear transmission group 6113 is transmission-connected to the first rotating plate 6114. The lower end of the first rotating plate 6114 is rotationally connected to the second rotating plate 6115, and a cleaning structure 612 is arranged at the lower end of the second rotating plate 6115. When the cooling effect of the chiller deteriorates, the bevel gear transmission group 6113 is driven by the driving motor 6112 to rotate the first rotating plate 6114, and the first rotating plate 6114 and the second rotating plate 6115 are in a closed state, while the ball valve 6111 is opened, so that the refrigerant is circulated and the cleaning wind wheel 6122 rotates, and the cleaning brush 61221 on the cleaning wind wheel 6122 removes impurities on the filter plate 6121 to avoid blockage.

[0036] The cleaning structure 612 includes a filter plate 6121, which is connected to the upper cover sleeve 6123. The upper cover sleeve 6123 is provided with an air inlet 61231 and an air outlet 61232. The air inlet 61231 is connected to the guide pipe 5. The air outlet 61232 is provided with an intercepting mesh plate 6125. The intercepting mesh plate 6125 can prevent impurities from flowing out and remaining on the collecting cover sleeve 6124 for manual collection and removal. The air outlet 61232 is connected to the return pipe 8 through a ball valve 6111. The top of the upper cover sleeve 6123 is connected to the heating sleeve 62. The middle position of the lower end of the filter plate 6121 is rotatably connected to the cleaning wind wheel 6122. A collecting cover sleeve 6124 is provided at the lower end of the cleaning wind wheel 6122. The collecting cover sleeve 6124 is connected to the upper cover sleeve 6123 by bolts. A cleaning brush 61221 is provided on the top surface and outer ring of the cleaning wind wheel 6122.

[0037] The heating sleeve 62 includes an insulating outer tube 621, a heat-conducting copper tube 624 is arranged inside the insulating outer tube 621, a desiccant is arranged inside the heat-conducting copper tube 624, and a heating tube 622 is arranged between the insulating outer tube 621 and the heat-conducting copper tube 624. The desiccant that absorbs moisture is heated by the heating tube 622 to be dried and reused.

[0038] Pure water 623 is arranged between the insulating outer tube 621 and the heat-conducting copper tube 624. The pure water 623 has excellent thermal conductivity and higher thermal conductivity efficiency than air, thereby helping to provide a more stable and reliable heating environment for the desiccant, making the heating and drying of the desiccant in the heat-conducting copper tube 624 more uniform and efficient.

[0039] The shaft end of the cleaning wind wheel 6122 is connected to the shaft end of the rotating blade 64. The rotating blade 64 is arranged in the heat-conducting copper tube 624. The top of the rotating blade 64 is slidingly connected to the pressing structure 65, and the bottom of the rotating blade 64 is connected to the first blocking mesh plate 63.

[0040] The pressed structure 65 includes a second blocking mesh plate 651, which is slidably connected to the top of the rotating blade 64. The middle position of the top of the second blocking mesh plate 651 is connected to one end of the elastic member 652, and the other end of the elastic member 652 is connected to the top of the rotating blade 64. The pressing of the second blocking mesh plate 651 of the pressed structure 65 can ensure that the solid particles of the desiccant are arranged more closely, thereby improving the filtration efficiency.

[0041] The working principle and use process of the present invention are as follows: the refrigerant enters the evaporator 1 after being directly reduced in pressure and temperature through a throttle valve. The refrigerant in the evaporator 1 evaporates into a gaseous refrigerant after absorbing heat. The gaseous refrigerant enters the compressor in the machine body 4 through an intake pressure regulating valve 3 to ensure that the evaporation pressure is maintained at a set value. The compressor inhales the gaseous refrigerant to increase its temperature and pressure. The high-temperature and high-pressure gaseous refrigerant enters the condenser 2 through an exhaust pipe. In the condenser 2, the high-temperature and high-pressure refrigerant releases heat by heat dissipation, and the gaseous refrigerant is thereby cooled and converted into liquid. The liquid refrigerant passes through the filter plate 6121 and the desiccant in the drying and filtering device 6 to remove impurities and moisture. When the cooling effect of the chiller becomes worse, the bevel gear transmission group 6113 is driven by the driving motor 6112 to drive the first rotating plate 6114 to rotate. The first rotating plate 6114 and the second rotating plate 6115 are in a closed state while the ball valve 6111 is opened, and the refrigerant will drive the cleaning wind wheel 6122 to rotate, and the impurities on the filter plate 6121 are removed by the cleaning brush 61221. At the same time, the heating tube 622 in the insulation outer tube 621 heats the pure water 623 to conduct heat to the heat-conducting copper tube 624. The heat-conducting copper tube 624 heats the molecular sieve and activated alumina in the desiccant to remove moisture. The evaporation of moisture forms steam and is discharged through the two-way valve 7. At the same time, the rotation of the cleaning wind wheel 6122 drives the rotating blades 64 to rotate. The rotating blades 64 drive the molecular sieve and activated alumina to rotate for more comprehensive heating, thereby improving the heating efficiency of the molecular sieve and activated alumina, so that the molecular sieve and activated alumina can be used again, thereby improving the utilization rate and extending the service life of the drying and filtering device 6.
