Description

Gas stove

Technical Field

The utility model relates to the field of stoves, in particular to a gas stove.

Background

Gas cookers are widely used in families and restaurant today, and a burner of a general gas cooker comprises a burner head, a central fire cover, an outer ring fire cover and the like, and a pot support is arranged on the burner so that a pot can be placed above the burner. The pot support belongs to the auxiliary structure of modern cookware, and the variety of current pot is various, like frying pan, soup pot, steamer etc. when using, according to culinary art mode and food characteristic select with different grade type's pot, also operate according to the different materials of pot.

The pot holders commonly used at present, such as the chinese patent application No. 201480020493.3, which discloses a pot holder for a gas burner, a pot holder device and a gas cooker, have at least three spacers arranged to be placed on a support surface for the pot holder, the spacers having a first end surface and a second end surface arranged opposite to each other, the second end surface being a flat support surface, the first end surface being adapted for a cooking food container having an arched bottom, the second end surface being adapted for a cooking food container having a flat bottom, the pot holder being arranged in a reversible manner to accommodate the different cooking food containers mentioned above. When the bottom of the pan is directly supported on the supporting parts, flame directly overflows from between the supporting parts due to the limitation of the shape of the pan, so that a large amount of heat is lost; in addition, the flame burns the spacer of the gas cooker pot support.

In order to avoid that flames directly burn a spacer frame (a pot support leg) of a gas cooker pot support and cause heat loss and damage to the pot support, a mode that no fire hole is arranged at a position corresponding to the pot support leg of a fire cover is adopted at present is generally adopted, the fire cover needs to be adjusted and the position of the fire cover, which does not fire the fire hole, is always corresponding to the support leg, the fire cover is inconvenient to use, higher requirements are met on the fixation of the fire cover, and in addition, the fire cover, which does not fire the fire hole, needs to be matched with the corresponding pot support, so that the use limitation of the fire cover is large.

Disclosure of Invention

Aiming at the current state of the art, the utility model provides the gas stove which can avoid burning the pot support and further achieve the purpose of energy saving.
