Description

Great for gas stoves {GRATE FOR GAS RANGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a grill for a gas stove, and more particularly, to a grill for a gas stove in which an overheat preventing portion for preventing overheating of the container is provided on a pedestal of one of a plurality of pedestals.

Generally, a gas stove is a device for efficiently burning gaseous fuels to obtain a high-temperature flame, and there are various forms ranging from a small-scale domestic gas stove to a large-scale industrial use for a boiler of a thermal power plant. There are two types of preliminary mixing and diffusion.

For example, the gas stove structure of the prior art includes a burner for discharging a flame, the burner being disposed at an upper edge of a mixing tube of a straight tube structure and having a penetrating portion penetrating vertically at the center thereof, And a lower end portion thereof is inserted into the mixing tube through a central penetrating portion of the burner body to form an air flow path and a gas flow path inwardly and outwardly of the lower end portion and the upper end portion thereof is placed on the upper end portion of the burner body, And a burner cap disposed above the burner head, and the like.

The edge of the burner head is provided with a support plate and a plurality of pedestals connected to one end of the support plate and one end thereof extending toward the upper side of the burner.

An overheat sensing unit is provided in the mixing tube so as to extend from the penetrating portion of the burner body to detect overheating of the container.

In the conventional gas stove having such a configuration, the mixed gas supplied through the mixing tube is ejected through the air hole between the burner body and the burner head, so that the flame is generated to perform the cooking.

The overheat sensing unit, which is in close contact with the bottom surface of the container during cooking, senses the overheating of the container so that the gas stove can be operated properly.

However, since the conventional gas stove has a structure in which the overheat sensing part is disposed inside the mixing pipe, it interferes with the flow of the secondary air supplied through the mixing pipe, thereby causing a shortage of the secondary air The amount of carbon monoxide increases and causes lifting.
