[0002] Gas-fired wok stoves are an important type of kitchen equipment, especially suitable for commercial kitchens such as large canteens in schools and factories, as well as restaurants. Designed for stir-frying, braising, steaming, and boiling large pots of food, gas-fired wok stoves are sturdy, durable, provide even heat, and are energy-efficient. Typically with a diameter of 80cm or more, they can meet the needs of large-volume cooking. With their high efficiency, strong heat, ease of operation, and safety, gas-fired wok stoves have become an indispensable piece of equipment in commercial kitchens. They not only improve cooking efficiency but also reduce fuel costs, making them an ideal choice for canteens and restaurants.

[0003] Large wok stoves have poor heat insulation when in use. The inside of the stove is insulated by pasting mud, which reduces its lifespan over time. When the flue gas is discharged, it does not have the function of recycling and purifying it for reuse, resulting in poor suitability for kitchen use. Therefore, there is an urgent need for a heat-conducting large wok stove to overcome the above defects. Utility Model Content
