Upper air inlet gas cookware

Abstract

The invention discloses upper air inlet gas cookware, belongs to gas cookware and solves the problems of inadequate combustion, low efficiency and small power caused by poor ejection capacity of the conventional gas cookware. In the upper air inlet gas cookware, a burner base is provided with a central ejector pipe and is connected with two side ejector pipes, an annular groove is formed on the upper surface of the burner base, an air admission hole is formed on one side face of the burner base and legs are arranged at the bottom of the burner base; a circular path is formed on the lower end face of an outer ring fire cover, fire holes are formed on the outer circumference of the outer ring fire cover and a central fire cover is arranged in the center of the outer ring fire cover; and a central gas nozzle and a central gas interface are arranged at the bottom of the gas ejection base and two spray pipes aligned with two side ejector pipe inlets respectively are arranged on the upper surface of the gas ejection base. The upper air inlet gas cookware improves gas inlet capacity, mixes gas uniformly, has adequate combustion and increases power; and foreign matters cannot enter a shell, so that the health of consumers is facilitated. By the upper air inlet gas cookware, the heat absorption efficiency of a pot can reach 55 percent; the emissions of CO and NOx is lower than 400ppm and 300ppm respectively which are far below the national energy-saving environmental protection index.

Description

technical field [0001] The invention belongs to a gas cooker, in particular to an upward air intake gas cooker. Background technique [0002] Modern kitchens require that the installation and use of built-in stoves must ensure that the air required for combustion is obtained from above the panel. The existing upward air intake stoves on the market include burner bases, ejector pipes, outer ring fire covers and center fire covers. The ejector tube is connected to the burner base, but the distance between the ejector tube inlet and the burner base is relatively large. Since the upward air intake requires all the air to enter from the upper part of the panel, the current position of the ejector tube is lower, and the air flows from the upper part of the panel. The distance to the entrance of the injection tube is relatively long, resulting in poor injection capability of the existing injection tube, small amount of air entering the injection tube, insufficient mixing of gas and...
