The heating technology of water dispensers is achieved through electric heating elements, usually including electric heating tubes or electric heating wires.
Structure of electric heating element:
The electric heating element is the core component for heating in the water dispenser. It usually includes one or more electric heating tubes or electric heating wires. These elements are usually installed inside the hot water storage tank of the water dispenser.
Electric heating tube: An electric heating tube is a component with a conductive material wrapped in an insulating material. When current passes through, the conductive material will heat and generate heat. It has high pressure resistance and good corrosion resistance, so it is often used in water dispensers.
Heating wire: Heating wire is a filament-shaped conductive material. When current passes through, the resistance heats up and generates heat. The diameter and length of the heating wire can be adjusted as needed to meet different heating needs.
Temperature Control System:
In order to ensure that the temperature of the hot water provided is stable within the range required by the user, water dispensers are usually equipped with a temperature control system. The temperature control system can monitor the water temperature and automatically adjust the working time of the electric heating element according to the user's settings.
Temperature sensor: The temperature sensor is usually placed in the hot water storage tank of the water dispenser and can monitor the water temperature in real time. When the water temperature is lower than the set value, the temperature control system starts the electric heating element.
Control circuit: The control circuit is responsible for receiving signals from the temperature sensor and controlling the on and off of the electric heating element according to the set temperature requirements. This ensures a constant temperature supply of hot water.
Heating process:
When the user selects hot water, the control circuit activates the electric heating element. When electric current passes through the electric heating tube or electric heating wire, the heat generated is transferred to the water in the storage tank due to the principle of resistance heating. This process quickly raises the water temperature to within the set temperature range.
Hot water storage tank:
Some water dispensers are designed with hot water storage tanks to store preheated hot water so that users can access it at any time. This design ensures users have immediate access to warm drinking water when needed.
