Function Description
The Hitachi multi-door refrigerator-freezer is designed to preserve food freshness and nutrients through advanced cooling technologies. It features several specialized compartments, each with specific functions to optimize food storage.
Refrigerator Compartment (Pg. 40, 44-45):
This compartment maintains a temperature range of approximately 2°C to 6°C, ideal for general refrigerating food. It includes:
- LED lamp: Provides illumination inside the compartment.
- Quick Cooling Corner: Designed for faster cooling of items.
- Height adjustable upper, middle, and lower shelves: Allow users to customize storage space based on food and beverage sizes.
- Fixed shelf: A non-adjustable shelf for stable storage.
- Pockets and Double door pockets: Located on the door for storing bottles and smaller items.
- Egg stand: Specifically designed for egg storage.
- Temperature Sensor: Monitors and helps maintain the desired temperature.
Vacuum Compartment (Pg. 40, 46-47):
Operating at approximately -1°C to 1°C, this compartment is designed for fresh foods like meat, fish, and seafood. Its key features include:
- Photocatalyst & LED light: Utilizes LED light and photocatalyst effects to convert odorous substances and ethylene gas into carbon dioxide, restricting enzyme activity and preserving nutrients and freshness.
- Vacuum Pump: Creates a vacuum state (approx. 0.8 hPa) to restrict oxidation, maintaining freshness and nutrients.
- Antioxidation Fresh Cassette: Releases antioxidant constituents and hot flavor to further preserve food. This cassette does not require periodic replacement.
- Vacuum release valve (in blue): Allows for easy release of the vacuum when opening the compartment.
- Vacuum Case (with an aluminum tray): The main storage unit within the vacuum compartment.
Ice Compartment (Automatic Ice Maker) (Pg. 40, 50-51):
This compartment maintains a temperature of approximately -20°C to -18°C and is dedicated to storing ice cubes made by the automatic ice maker. It includes:
- Water Supply Container: Holds water for ice making (approx. 1.0 L).
- Ice Case: Stores the automatically made ice cubes.
- Ice scoop: Provided for convenient ice retrieval.
- Ice Tray: The component where ice is formed.
Upper/Lower Freezer (Pg. 40, 48-49):
Both upper and lower freezer compartments maintain a temperature of approximately -20°C to -18°C, suitable for frozen food, ice cream, and dried food.
- Upper Freezer case (with an aluminum tray): Can be used as a Quick Freezing Corner for rapid freezing of meat and fish.
- 3-layer freezer case (Lower Freezer): Provides ample storage space with a Slimline slide case, Slide case, and Lower freezer case, allowing for organized storage of various frozen items.
- Tall Storage Compartment: Designed for tall items like 2L PET bottles.
Vegetable Compartment (Pg. 40, 52-53):
This compartment operates at approximately 3°C to 7°C, ideal for storing vegetables, fruits, and drinks. It is divided into:
- Upper space: For unfinished vegetables, small vegetables, and fruits.
- Tall Storage Compartment: For tall vegetables and 2L PET bottles.
- Aero-care Zone: Specifically designed for leaf vegetables (spinach, Japanese Mustard Spinach, etc.) and large vegetables (cabbage, lettuce), utilizing photocatalyst and LED light to maintain freshness and prevent drying.
