how do ice machines in fridges work

Ice machines in fridges, also known as ice makers, are one of the most commonly used appliances in modern households. Not only do they help us cool our drinks in hot summers, but they have also become almost a necessity for homeowners who love to entertain. Have you ever wondered how they work? If you have, then read on as we take you through how ice machines in fridges work.

1. Introduction to Ice Machines in Fridges

An ice machine is comprised of several components, including a motor, a water valve, a heating element, and a thermostat. The motor drives a gear that rotates the ice tray inside the freezer. Once the tray is positioned in the right place, the water valve sends water to the tray. The cooling element in the freezer, also known as the evaporator, then freezes the water making ice. When the ice is ready, the motor then rotates the tray to release the ice cubes into a storage bin located in the fridge.

2. How Does the Water Get into the Tray?

Before you can have ice, water has to go into the tray. The water valve in the fridge receives a signal from the ice machine control that opens the valve to let water flow into the tray. The valve only opens to allow a specific amount of water to enter the tray. Once that amount is reached, the valve closes, and a sensor checks the water level.

3. Freezing Water in the Ice Tray

Once the tray is filled with water, it is then put into the freezer compartment. The cooling element in the freezer helps to reduce the temperature and freeze the water in the tray. The temperature in the freezer is usually around zero degrees Celsius, which is cold enough to freeze the water.

4. How Long Does It Take for the Water to Freeze?

The cooling element of the freezer cools the water in the tray until it reaches the freezing point. The freezing time varies depending on the size of the ice cubes, the temperature inside the freezer, and other factors like the water's hardness. Generally, it can take anywhere from 90 minutes to two hours to freeze the water completely.

5. Releasing Ice Cubes from the Tray

Once the water in the tray is completely frozen, the ice maker starts to work again. The motor is activated, and it rotates the tray to dislodge the ice cubes from the tray. Because the tray contains raised rows, the ice cubes can easily be removed from the tray and dropped into a storage bin located in the fridge.

6. Conclusion

In conclusion, ice machines in fridges work by taking water from the fridge's water supply, filling the ice tray, and freezing it in the freezer compartment until it is ready. The motor then rotates the tray to release the ice cubes into a storage bin in the fridge that can be used whenever you need them. Understanding how ice machines in fridges work can help you appreciate this essential home appliance and troubleshoot any issues that may arise.
