Outer ring burner cap for combustor, combustor and gas stove

Abstract

The invention discloses an outer ring burner cap for a combustor, the combustor and a gas stove, and belongs to the technical field of gas stoves. The outer ring burner cap comprises a burner cap body, wherein the burner cap body is provided with a gas mixing chamber and burner ports, the gas mixing chamber is annular and provided with a downward opening, the two ends of each burner port are located on the wall face of the gas mixing chamber and the outer side face of the burner cap body respectively, and the burner ports are formed in the circumferential direction of the burner cap body at intervals; the upper edge of the burner cap body is of a cornice structure, and the cornice structure protrudes out of the burner ports in the radial direction of the burner cap body; and a flow guide groove is formed in the upper surface of the burner cap body and extends in the circumferential direction of the burner cap body. By arranging the cornice structure and the flow guide groove, overflowing liquid is prevented from flowing to the burner ports, the burner ports are prevented from being blocked, smoke is gathered, the flow direction of the smoke is disturbed, the smoke staying time is prolonged, and therefore the energy efficiency is improved while the burner ports are prevented from being blocked.

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...
