Abstract

This invention discloses a method for controlling the constant temperature of a natural gas oven, specifically a natural gas oven for baking. The oven body has an interior for placing food and sealing it for heating. A heating isolation device is located around the inner wall of the oven body, isolating the food from the flame and ensuring stable and even heat conduction. A blocking component rotates inside the heating isolation device, pre-mixing the gas within it to promote more complete combustion. This invention allows for the counter-mixing of oxygen and gas, enabling oxygen to better assist combustion and maintain a constant oven temperature. This, in turn, ensures that food is baked at a constant temperature, guaranteeing optimal taste.

Description

Technical Field

[0001] This invention relates to the field of natural gas oven technology, specifically to a constant temperature control system and method for a natural gas oven used for baking. Background Technology

[0002] Gas-fired barbecue grills are typically made of forged stainless steel. When in operation, they are ignited by electronic pulse, much like the liquefied petroleum gas (LPG) stoves used in homes. LPG and natural gas are generally used as fuel for these grills. After the valve is opened, the electronic pulse ignites the gas and generates heat, which is then transferred to the four independent high-temperature resistant gas heating plates at the top, thus baking the food.

[0003] When existing natural gas ovens are used in the baking field, since baked goods are generally cakes or bread, large temperature fluctuations in the natural gas oven can easily lead to undercooked or burnt food, resulting in a bitter taste. Therefore, it is necessary to control the oven temperature. However, existing natural gas ovens heat food by injecting and burning gas. During combustion, instability in the amount of gas injected or incomplete combustion in the air can affect the combustion temperature, leading to temperature differences within the oven and causing problems with the baked food. To address this, we propose a constant temperature control system and method for natural gas ovens used in baking. Summary of the Invention
