The Crown Top Loading Water Dispenser, model WD-194, is a household appliance designed to dispense both hot and cold water. Here are some common features and specifications you might find with this type of water dispenser:

1. Top Loading Design: This means that you load the water bottle from the top of the dispenser, typically by flipping open a lid and placing the bottle upside down onto a prong.

2. Hot and Cold Water Options: These dispensers usually have two faucets or buttons, one for dispensing hot water and the other for cold water. The hot water option is often used for making hot beverages like tea or instant coffee, while the cold water option provides refreshing drinking water.

3. Cooling and Heating Mechanisms: The cold water is cooled using a refrigeration system, while the hot water is heated using a heating element. These mechanisms ensure that the water is maintained at the desired temperature.

4. Safety Features: Hot water faucets on these dispensers typically come with safety locks or guards to prevent accidental dispensing, especially important if there are children around.

5. Storage Cabinet: Some models may also include a storage cabinet at the bottom, providing space to store cups, bottles, or other small items.

6. Energy Efficiency: Many modern water dispensers are designed with energy-saving features to minimize electricity consumption, particularly for heating and cooling functions.

7. Cleaning and Maintenance: Regular cleaning and maintenance are important to keep the dispenser functioning properly and to ensure the water remains safe for consumption. This may involve periodic cleaning of the water reservoir, replacement of filters (if applicable), and general upkeep of the dispenser's exterior.
