The principle of automatic ice maker machine

The structure of the automatic ice maker can be roughly divided into three parts: the control box, the intermediate connection box and the ice box. The control box is the core component, and its internal structure consists of a motor, a reduction gear, a shaft and a copper sheet.

When the ice maker is powered on, the motor drives the shaft to rotate through the reduction gear. When the shaft is in different positions, it triggers different copper sheets to connect and disconnect, forming different circuit connections, thereby realizing the actions of each stage in the ice making process.

The intermediate connection box is mainly used to connect the control box and the ice box. A bimetallic thermostat is fixed on its shell. After the ice maker is assembled, the thermostat will be tightly attached to the ice container body to control the ice making time and the heating time of the heater; the ice box is mainly composed of an ice probe rod, an ice separation rod, an ice container and a heater. When the ice cubes in the ice storage box (usually located below the ice maker) in the refrigerator are full, the ice cubes will push the ice probe rod upward, thereby cutting off the operation of the ice maker. At the same time, the ice probe can also be used as a manual forced stop device. The ice separation rod is an ice separation device connected to the shaft. The ice making container is a cast aluminum part, which can make eight large ice cubes at a time. The heater is close to the bottom of the ice making container. When the ice cubes are made, the heater is turned on for heating, and the shaft rotates to a certain position to drive the ice separation rod to push the ice cubes out of the ice making container and fall into the ice storage box below.
