Burner for gas cooker

Abstract

The invention discloses a burner for a gas cooker. The burner comprises a base, wherein a main fire gas outlet pipe is arranged on the base, and a central fire gas outlet pipe is arranged in the central position of the main fire gas outlet pipe; a main fire injection pipe and a central fire injection pipe are arranged in the bottom of the base; an upper air inlet cavity is connected to the gas inlet ends of the main fire gas outlet pipe and the central fire gas outlet pipe; a main fire gas inlet pipe and a central fire gas inlet pipe are arranged on one side of the upper air inlet cavity; the gas inlet ends of the main fire gas inlet pipe and the central fire gas inlet pipe extend into the upper air inlet cavity and are arranged opposite to the gas inlet ends of the main fire injection pipe and the central fire injection pipe in the cavity, respectively; the gas outlet end of the main fire injection pipe communicates with a fan-shaped arc-shaped channel which communicates with a straight channel, and the straight channel communicates with the main fire gas outlet pipe. By adopting the structure, the burner for the gas cooker disclosed by the invention has the characteristics of high thermal load, great firepower, high thermal efficiency, liability to replace nozzles, convenience in maintenance, safety in use and the like.

Description

technical field [0001] The invention discloses a burner for a gas cooker, which belongs to the technical field of the gas cooker. Background technique [0002] Existing gas cooker burners can be divided into two types of structures, a bottom air intake type and an upper air intake type, from the supplementary manner of the primary air. Traditional gas stove burners generally belong to the bottom air intake structure, that is, the primary air comes from the inner cavity of the cooker, and the bottom of the inner cavity needs to reserve an air intake hole for supplementary primary air. This method is conducive to the supplement of primary air and reduces The temperature of the inner cavity of the cooker, but the cabinet door needs to have enough ventilation holes. When the cabinet door is opened, it will have a certain impact on the combustion conditions of the cooker; especially when tempering occurs for some reason, it is not easy to be found and it will burn out The combus...

Traditional gas stove burners generally belong to the bottom air intake structure, that is, the primary air comes from the inner cavity of the cooker, and the bottom of the inner cavity needs to reserve an air intake hole for supplementary primary air. This method is conducive to the supplement of primary air and reduces The temperature of the inner cavity of the cooker, but the cabinet door needs to have enough ventilation holes. When the cabinet door is opened, it will have a certain impact on the combustion conditions of the cooker; especially when tempering occurs for some reason, it is not easy to be found and it will burn out The combustible parts in the inner cavity of the cooker pose a safety hazard, and the impurities in the gas pipeline and the gas composition can easily cause the nozzle to be blocked or the aperture to become smaller. The panel needs to be opened to clean and replace the nozzle, which is extremely inconvenient and brings trouble to maintenance

The updraft burner is imported from European countries, that is, the primary air comes from the stove top, even if tempering occurs, it will be easy to be found, and it will not cause accidents if it is dealt with in time. The requirements for the size of the firepower are different. The heat load of the upward-inlet burner is often too small, which is difficult to meet the firepower requirements of the Chinese people for gas cookers. This is mainly due to the structure and manufacturing process of the ejector tube of the existing upward-inlet burner. It is often designed as a relatively short straight-through pipe. The ejection capacity of the primary air is much worse than that of the Venturi tube used in the traditional downdraft burner. The primary air coefficient is small and a large amount of secondary air is required. In order to burn normally, the heat intensity of the fire hole is low, so the head diameter of this kind of upward air-intake burner is large, the heat load is relatively small, and the thermal efficiency is low
