Description

Technical Field

[0001] This utility model relates to a gas oven. Background Technology

[0002] Currently, most gas ovens on the market use traditional thermostatic valves. They cannot automatically shut off the heat by setting a cooking time; they can only ignite the lower or upper burner, resulting in uneven temperature distribution. This leads to inconsistent coloring during baking, with one side becoming golden brown while the other remains uncooked. The minimum temperature control exceeds 130℃, which is insufficient for low-temperature baking requirements, such as fermentation and defrosting. Furthermore, they cannot keep pace with rapid technological advancements. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technology and provide a gas oven that can simultaneously control the operation of the lower and upper combustion components. It is controlled by a combination of a display screen, a pulse controller, and a proportional valve group. The power level is set via a sliding screen, which drives the pulse controller to output a DC voltage value to the proportional valve group. A higher voltage value results in a larger opening of the proportional valve group, more gas output, and a stronger fire; a lower voltage value results in a smaller opening of the proportional valve group, less gas output, and a weaker fire. Furthermore, the sliding screen controller allows setting the cooking time. Once the cooking time countdown reaches zero, the pulse controller stops outputting the proportional valve group control voltage, thus achieving a timed shut-off function. It is convenient to use and has a compact structure.

[0010] The advantages of this invention compared to existing technologies are as follows: it can simultaneously control the operation of the lower and upper combustion components. Control is achieved through a combination of a display screen, pulse controller, and proportional valve group. The power level is set via a sliding screen control, which drives the pulse controller to output a DC voltage value to the proportional valve group.
