This document describes a Smeg induction hob, model SIH7933B, designed for household cooking. It emphasizes safety, proper installation, and efficient use.
Function Description
The Smeg induction hob utilizes electromagnetic fields to directly heat the bottom of cookware, ensuring efficient and rapid cooking. The glass ceramic surface itself is heated by the cookware, not directly by the hob. It features three induction cooking zones, each with its own heat setting display and timer indicators.
Key functions include:
- Activation and Deactivation: The hob can be activated or deactivated by touching a dedicated sensor field for one second.
- Heat Setting: Users can set or change the heat setting by touching or sliding a finger along a control bar. The hob offers a range of heat settings from 1 to 14.
- Automatic Switch Off: For safety and energy saving, the hob automatically deactivates if all cooking zones are off, no heat setting is selected after activation, an object is on the control panel for too long, the hob overheats, incorrect cookware is used, or a cooking zone is left active without changes for an extended period. The duration before automatic switch-off varies based on the heat setting.
- Accelerator Function: This function allows a desired heat setting to be reached in a shorter time by operating the zone at its highest setting initially, then reverting to the selected setting.
- Power Function: This provides additional power to induction cooking zones for a limited time, after which the zone automatically reverts to its highest heat setting. This is useful for rapid boiling or searing.
- Count Down Timer: This function allows users to set a specific cooking duration for a zone. Once the time elapses, an acoustic signal sounds, and the cooking zone deactivates.
- Count Up Timer: This function monitors how long a cooking zone has been operating, displaying the elapsed time.
- Minute Minder: This can be used as a standalone timer when the hob is active but cooking zones are not operating.
- Pause Function: This sets all active cooking zones to the lowest heat setting (1) and locks other control panel symbols, allowing temporary interruption of cooking without losing settings.
- Lock / Child Safety Device: The control panel can be locked to prevent accidental changes to heat settings during operation. A separate child safety device prevents accidental activation of the hob altogether.
- OffSound Control: This feature allows users to deactivate or activate the acoustic signals of the hob, except for critical alerts like the Minute Minder or Count Down Timer.
- Power Limitation: The hob has a maximum power level, which can be adjusted to suit household electrical installations. This function manages power distribution across cooking zones, especially when the total electricity loading exceeds 3600 W per phase.
- Eco-Off (Eco Timer): To save energy, the heating element of a cooking zone deactivates before the set count-down timer sounds, with the difference in operation time depending on the heat setting and cooking duration.
- Auto-Vent: This advanced automatic function connects the hob to a compatible hood via infrared signals. The hood's fan speed is automatically adjusted based on the hob's mode setting and the temperature of the hottest cookware. Users can also operate the fan manually from the hob.
Usage Features
The hob is designed for intuitive operation through its sensor fields and displays.
- Cookware Compatibility: Induction zones require suitable cookware made of magnetic materials like cast iron, steel, enamelled steel, or multi-layer bottom stainless steel. Cookware should have a thick, flat, and clean base for optimal performance. The hob automatically adapts to the cookware's bottom dimension.
- Cooking Zone Placement: Cookware should be placed in the center of the selected zone.
- Residual Heat Indicator (Eco-Heat): A 3-step indicator shows the level of residual heat, warning against burns and potentially lowering the heat setting of neighboring zones if a zone becomes too hot.
- Noise During Operation: Various noises (crack, whistle, humming, clicking, hissing/buzzing) are normal during induction cooking and do not indicate a malfunction. These are often related to cookware material, power level, or fan operation.
- Energy Saving Tips: Recommendations include using only necessary water, always using lids, placing cookware on the zone before activation, using smaller cookware on smaller zones, centering cookware, and utilizing residual heat.
Maintenance Features
Regular cleaning and proper care are essential for maintaining the hob's performance and appearance.
- Regular Cleaning: The hob should be cleaned after each use to prevent deterioration of the surface material.
- Cooling Down: Always deactivate the appliance and allow it to cool down before cleaning.
- Cleaning Agents: Use a moist soft cloth and neutral detergents. Avoid abrasive products, abrasive cleaning pads, solvents, or metal objects.
- Special Scraper: A special scraper is recommended for removing melted plastic, sugar, or food with sugar immediately. For limescale rings, water rings, fat stains, or shiny metallic discoloration, wait until the hob is sufficiently cool, then use a moist cloth and non-abrasive detergent. For shiny metallic discoloration, a solution of water with vinegar can be used.
- Electrical Disconnection: Disconnect the appliance from the electrical supply before maintenance.
- Service and Repair: In case of malfunction or damage, contact an Authorized Service Centre and use only original spare parts. Do not attempt to repair the appliance yourself.
- Disposal: Dispose of packaging and the appliance itself according to municipal regulations, ensuring proper recycling and environmental protection.
