Description

Technical Field

[0001] This utility model relates to the technical field of gas stoves, and more specifically, to improvements in direct injection energy-saving burners. Background Art

[0002] In the current market environment, we can see that direct-injection burners on the market have significant limitations in their air supply methods. These direct-injection burners mainly rely on a hollow design at the bottom of the burner to achieve the crucial function of air supply through the area below the cooktop, with the direct-injection nozzle installed below this hollow area. This design structure fundamentally determines that it only has a single, limited air intake path, completely lacking multiple air supply capabilities. When the cooktop is embedded in a cabinet, both direct-injection combustion and inner / outer ring combustion can only obtain oxygen through a single bottom air intake, which can easily lead to oxygen deficiency in the confined space.

[0003] In terms of cleaning, its complex internal structure and hard-to-reach corners make it easy for dirt and debris to accumulate. Furthermore, the lack of a proper cleaning path and convenient disassembly method makes thorough cleaning difficult for users. Over time, this dirt and debris not only affects the normal operation of the burner but also breeds bacteria, producing unpleasant odors and seriously impacting the user environment.

[0004] Furthermore, the burner head is prone to clogging of the direct-injection nozzles during use, which users cannot disassemble to clean themselves. This not only interferes with ongoing cooking activities but may even lead to safety accidents. Moreover, the perforated design at the bottom makes the burner head susceptible to external factors, allowing water and various contaminants to easily enter. Water ingress can cause short circuits or corrosion of internal components; while contaminants further complicate cleaning and produce unpleasant odors.

[0005] From a combustion performance perspective, this type of direct-injection burner lacks multiple air supply capabilities. When the cooktop is embedded in a cabinet, the direct-injection combustion and inner / outer ring combustion rely solely on bottom air intake within the cabinet for oxygen replenishment. This limited space leads to insufficient oxygen and a high risk of oxygen deficiency. Furthermore, the central flame of the direct-injection burner often fails to burn completely. During combustion, the gas cannot mix adequately with sufficient air, resulting in low combustion efficiency. Utility Model Content
