Outer ring fire covers for burners, burners and gas hobs

Abstract

The invention discloses an outer ring fire cover for a burner, a burner and a gas stove, and belongs to the technical field of gas stoves. The outer ring fire cover includes the fire cover body, the fire cover body has an air-mixing chamber and a fire hole, the air-mixing chamber is annular and the opening faces downward, and the two ends of the fire hole are respectively located on the wall of the air-mixing chamber and the outer surface of the fire cover body , the fire holes are arranged at intervals along the circumference of the fire cover body; the upper edge of the fire cover body is a cornice structure, and in the radial direction of the fire cover body, the cornice structure protrudes from the fire hole; the upper surface of the fire cover body has a diversion groove, The diversion groove extends along the circumferential direction of the fire cover body. The invention prevents the overflow from flowing to the fire hole by setting the eaves structure and the diversion groove, prevents the fire hole from being blocked, gathers the smoke gas and disturbs the flow direction of the smoke gas, and increases the residence time of the smoke gas. Improves energy efficiency while preventing clogging of the fire holes.

Description

technical field [0001] The invention relates to the technical field of gas stoves, in particular to an outer ring fire cover for a burner, a burner and a gas stove. Background technique [0002] As a common kitchen utensil, the performance of the gas stove affects people's quality of life. Existing gas stoves generally have the situation that the fire hole of the fire cover is blocked, mainly because the soup flows to the fire hole during cooking, and the solid left after the water evaporates blocks the fire hole. The current anti-blocking technology often sacrifices energy efficiency, resulting in low adaptability of gas stoves. When encountering pressure fluctuations, opening and closing cabinet doors or excessive air flow in the environment, the combustion performance will be reduced, the flame will be removed or the flame will be extinguished. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentio...
