Daul Mode stove

The Dual-Mode Stove is a versatile cooking appliance designed to operate on both Liquefied Petroleum Gas (LPG) and electric heat coil power sources. It allows users to switch seamlessly between gas and electric modes based on availability, cost-efficiency, or preference. This hybrid system ensures uninterrupted cooking during power outages or gas shortages, making it ideal for households in areas with inconsistent utility supply.

Key Features:

  • Dual power source: LPG and electric heat coil.

  • Manual or automatic mode switching for user convenience.

  • Energy-efficient and safe design with heat-resistant materials.

  • Ideal for rural, semi-urban, and urban settings with unstable power or gas supply.

Working of Dual-Mode Stove

The stove has two independent heating systems—one using LPG (gas burner) and the other using an electric heat coil. The user can switch between these modes depending on fuel availability or preference.

LPG Mode (Gas Burner)

  • Fuel Source: LPG cylinder connected via a regulator and pipe.

  • Ignition: Manual with a match/lighter or electric igniter.

  • Flame Control: Adjustable knob regulates gas flow and flame intensity.

  • Usage: Traditional cooking with direct flame; fast heating.

Electric Mode (Heat Coil)

  • Power Source: AC mains electricity.

  • Heating Element: Nichrome or similar high-resistance coil embedded under a metal plate.

  • Operation: When powered on, current flows through the coil → coil heats up → heat transfers to cookware.

  • Control: Temperature is regulated using a rotary dial or thermostat.

Mode Switching

  • A manual selector switch allows the user to choose either LPG or electric mode.

  • Safety interlock ensures only one mode runs at a time to avoid electrical or gas hazards.

  • Optional LED indicators show which mode is active.

Safety Features of Dual-Mode Stove

1. Flame Failure Safety Device (LPG Mode)
Automatically cuts off gas supply if the flame goes out unexpectedly, such as from wind or a liquid spill.
2. Overheat Protection (Electric Mode)
A thermal sensor disconnects power if the coil or hot plate exceeds a safe temperature threshold.
3. Insulated Body and Heat Shields
The stove uses heat-resistant, non-conductive materials to prevent accidental burns.
4. Safety Interlock for Mode Switching
Allows only one mode (LPG or electric) to run at a time, preventing simultaneous operation.
5. Gas Leak Detection Sensor (Optional but recommended)
Detects gas leaks and either alerts the user or automatically stops the gas flow.
6. Shock Protection (Electric Mode)
Includes grounding, insulation, and a fuse or circuit breaker to protect against electrical shock and power surges.
7. Child Safety Lock (Optional)
Prevents accidental ignition or switching by children.

Conclusion

The dual-mode stove, operating on both LPG and electric heat coil, offers a reliable and flexible solution for modern cooking needs. By allowing users to switch between gas and electric power, it ensures uninterrupted usage during fuel shortages or power cuts. With built-in safety features like flame failure protection, overheat cut-off, and insulated housing, it provides a safe and efficient cooking experience. This innovation is especially valuable in areas with inconsistent energy supply, making it a practical and sustainable addition to households.
