The refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items in a constant low temperature cold state. With the improvement of people's living standards, the amount of ice cubes used in people's lives is increasing. As an important part of the refrigerator, the ice maker has received widespread attention and love. At present, the ice-making methods in the refrigerator include manual ice making and automatic ice making. Among them, the automatic ice maker used for automatic ice making has attracted more and more attention.

After the air filter plate (11) has filtered for a period of time, start the servo motor (14), the output shaft of the servo motor (14) drives the rotating installed disc (15) to rotate, and when the rotating installed disc (15) rotates, the convex rod drives the lifting drive frame (16) to reciprocate and lift, so that the two lifting connecting plug rods (10) drive the air filter plate (11) to reciprocate and lift, and the dust on the surface of the air filter plate (11) is scraped off, and then the sealing door is opened, and the third installed induced draft fan (32) is started. Through the action of the third installed induced draft fan (32), the air is sent into the interior of the air purification box (2), and the dust inside the air purification box (2) is blown out; S2, when air enters the heat exchanger (6), the second induced draft fan (17) is started, and the low-temperature natural gas enters the interior of the heat exchanger (6) through the second connecting installation pipe (18). After heat exchange in the heat exchanger (6), the low-temperature air enters the interior of the fourth connecting installation pipe (20), and then enters the corresponding fifth connecting installation pipe (21), and then enters the plurality of seventh connecting installation pipes (23) through the sixth connecting installation pipe (22), and then enters the corresponding space of the ice making ice box (5) through the plurality of seventh connecting installation pipes (23), so as to cool the water inside the ice making mold (25) and make ice; S3, at the same time, the cold air in the refrigerator body (5) enters the serpentine cooling pipe (28) through the first connecting fixed pipe (27), and the cold air cools the water in the water storage tank (26) through the action of the serpentine cooling pipe (28), and finally the air is discharged through the multiple exhaust pipes (31); S4, after one ice making is completed, the ice making mold (25) is slid out and replaced with a new ice making mold (25), and then the water pump body (29) is started and connected to extract cold water from the water storage tank (26), and the cold water enters the ice making mold (25) through the second connecting fixed pipe (30), and the next ice making is continued.
